1 00:00:04,309 --> 00:00:01,750 are doing get ahead work for the eba 2 00:00:07,349 --> 00:00:04,319 crew there's also no bag for the crew to 3 00:00:09,589 --> 00:00:07,359 cut through when they arrive 4 00:00:12,629 --> 00:00:09,599 we then sep d mate again 5 00:00:14,870 --> 00:00:12,639 orion docks here and now the arms 6 00:00:16,950 --> 00:00:14,880 aid during the ebas 7 00:00:19,109 --> 00:00:16,960 just as the rms did during shuttle days 8 00:00:20,630 --> 00:00:19,119 and ssrms does 9 00:00:22,070 --> 00:00:20,640 uh now 10 00:00:23,990 --> 00:00:22,080 does it 11 00:00:26,150 --> 00:00:24,000 ssrms do they ever stand on the nfs's 12 00:00:28,310 --> 00:00:26,160 rms yeah 13 00:00:30,150 --> 00:00:28,320 so afterward the tug could then 14 00:00:33,030 --> 00:00:30,160 potentially be refueled replenish with 15 00:00:34,950 --> 00:00:33,040 xenon to go either get another one 16 00:00:36,790 --> 00:00:34,960 or to do other things that are 17 00:00:38,630 --> 00:00:36,800 extensible for the human exploration 18 00:00:40,069 --> 00:00:38,640 system 19 00:00:41,510 --> 00:00:40,079 tugs are a good thing to have in your 20 00:00:43,590 --> 00:00:41,520 back pocket if you're 21 00:00:45,430 --> 00:00:43,600 space faring nation 22 00:00:48,869 --> 00:00:45,440 so these are things that we are doing 23 00:00:51,029 --> 00:00:48,879 presently to advance the technology in 24 00:00:52,950 --> 00:00:51,039 some of these key areas we've got 25 00:00:54,869 --> 00:00:52,960 a refueling experiment up on space 26 00:00:57,430 --> 00:00:54,879 station right now that's involving 27 00:00:59,510 --> 00:00:57,440 advanced tools and i have no time but 28 00:01:01,990 --> 00:00:59,520 these the only point here is these are 29 00:01:03,910 --> 00:01:02,000 all photographs of hardware not cad 30 00:01:06,630 --> 00:01:03,920 renderings of what we're going to do but 31 00:01:08,310 --> 00:01:06,640 what we are doing now 32 00:01:10,630 --> 00:01:08,320 and these are those other missions take 33 00:01:14,630 --> 00:01:10,640 a picture quick 34 00:01:14,640 --> 00:01:17,270 thanks ben 35 00:01:21,990 --> 00:01:19,350 all right we keep proving how much how 36 00:01:23,270 --> 00:01:22,000 little time 10 minutes is um 37 00:01:25,350 --> 00:01:23,280 the next 38 00:01:27,990 --> 00:01:25,360 pair of speakers is 39 00:01:29,670 --> 00:01:28,000 michael esperman and manny liens from 40 00:01:31,910 --> 00:01:29,680 boeing company 41 00:01:34,230 --> 00:01:31,920 mike's the director of space science and 42 00:01:36,149 --> 00:01:34,240 advanced space utilization for boeing 43 00:01:38,550 --> 00:01:36,159 manny is the director of autonomous 44 00:01:40,230 --> 00:01:38,560 space capabilities and he will join the 45 00:01:42,230 --> 00:01:40,240 in the presentation they will address 46 00:01:44,469 --> 00:01:42,240 the inherent technical schedule and cost 47 00:01:46,710 --> 00:01:44,479 risks of the the challenging mission and 48 00:01:48,550 --> 00:01:46,720 discuss how designing the uh asteroid 49 00:01:50,310 --> 00:01:48,560 redirect systems to incorporate existing 50 00:01:52,630 --> 00:01:50,320 high heritage spacecraft systems and 51 00:01:54,870 --> 00:01:52,640 subsystems leveraging proven performance 52 00:01:56,389 --> 00:01:54,880 high reliability and associated 53 00:01:57,990 --> 00:01:56,399 investments and experience will reduce 54 00:01:59,749 --> 00:01:58,000 overall mission risk 55 00:02:01,910 --> 00:01:59,759 capitalizing on the extensive industry 56 00:02:04,230 --> 00:02:01,920 production and operations experience 57 00:02:06,149 --> 00:02:04,240 so mike 58 00:02:07,749 --> 00:02:06,159 my name is mike as 59 00:02:08,949 --> 00:02:07,759 jim said this is manny we're from the 60 00:02:10,070 --> 00:02:08,959 boeing company 61 00:02:11,510 --> 00:02:10,080 um we're today we're going to talk a 62 00:02:12,710 --> 00:02:11,520 little bit about 63 00:02:14,229 --> 00:02:12,720 maybe not so much the specific 64 00:02:15,589 --> 00:02:14,239 implementation of this mission but but 65 00:02:17,990 --> 00:02:15,599 ways to manage the risk that are 66 00:02:19,030 --> 00:02:18,000 inherent in just in a in a program of 67 00:02:21,270 --> 00:02:19,040 this uh 68 00:02:23,510 --> 00:02:21,280 magnitude which button is it jim 69 00:02:26,390 --> 00:02:23,520 for chart don't touch the bottom one um 70 00:02:27,990 --> 00:02:26,400 the full yeah okay figured it out so 71 00:02:30,070 --> 00:02:28,000 it's going to be broken into two parts 72 00:02:32,150 --> 00:02:30,080 i'm going to talk about uh similar 73 00:02:33,350 --> 00:02:32,160 concepts to what adam talked about a 74 00:02:35,190 --> 00:02:33,360 little bit what ben talked about how we 75 00:02:37,030 --> 00:02:35,200 maybe can leverage existing capabilities 76 00:02:38,390 --> 00:02:37,040 that are that exist within industry and 77 00:02:40,070 --> 00:02:38,400 that nasa has already invested in to 78 00:02:42,630 --> 00:02:40,080 really help manage and mitigate the 79 00:02:43,830 --> 00:02:42,640 asteroid system emission system risks 80 00:02:45,670 --> 00:02:43,840 and the man is going to talk about 81 00:02:47,750 --> 00:02:45,680 specifically some investments that have 82 00:02:48,869 --> 00:02:47,760 been done both by us and by nasa and 83 00:02:50,470 --> 00:02:48,879 autonomous rendezvous and docking 84 00:02:52,710 --> 00:02:50,480 terrain relative navigation how that can 85 00:02:55,110 --> 00:02:52,720 apply to the mission and also reduce the 86 00:02:57,509 --> 00:02:55,120 overall risk 87 00:02:59,190 --> 00:02:57,519 so as everybody 88 00:03:00,309 --> 00:02:59,200 i'm sure recognizes and has been said 89 00:03:01,910 --> 00:03:00,319 several times today it's a very 90 00:03:04,550 --> 00:03:01,920 ambitious program that nasa is trying to 91 00:03:06,869 --> 00:03:04,560 undertake lots of benefits to to the 92 00:03:08,070 --> 00:03:06,879 nation and to humanity 93 00:03:09,350 --> 00:03:08,080 and really trying to synergize the 94 00:03:10,550 --> 00:03:09,360 various things that are going on inside 95 00:03:12,470 --> 00:03:10,560 of nasa in terms of technology 96 00:03:14,149 --> 00:03:12,480 development mission execution 97 00:03:15,830 --> 00:03:14,159 science etc 98 00:03:17,430 --> 00:03:15,840 but there are a lot of as everybody 99 00:03:20,229 --> 00:03:17,440 realizes a lot of uncertainties on this 100 00:03:21,830 --> 00:03:20,239 particular mission uh which really drive 101 00:03:23,350 --> 00:03:21,840 up the risk it's already 102 00:03:25,350 --> 00:03:23,360 incorporating new technologies which 103 00:03:27,350 --> 00:03:25,360 have some inherent risks uh we're going 104 00:03:28,869 --> 00:03:27,360 further away than you know 105 00:03:30,869 --> 00:03:28,879 than we've done in a long time in terms 106 00:03:33,509 --> 00:03:30,879 of distance from earth 107 00:03:34,869 --> 00:03:33,519 so the asteroid they've talked about 108 00:03:36,869 --> 00:03:34,879 the uncertainty in its mass and that 109 00:03:38,470 --> 00:03:36,879 drive system performance parameters 110 00:03:39,910 --> 00:03:38,480 launch date launch vehicle those are 111 00:03:41,430 --> 00:03:39,920 trades that that 112 00:03:43,750 --> 00:03:41,440 are also uncertain 113 00:03:45,350 --> 00:03:43,760 and then a real risk i think is the very 114 00:03:47,509 --> 00:03:45,360 ambitious schedule that that has been 115 00:03:48,949 --> 00:03:47,519 proposed uh concurrent technology 116 00:03:50,229 --> 00:03:48,959 development at the same time that you're 117 00:03:51,830 --> 00:03:50,239 designing the mission and the mission 118 00:03:53,030 --> 00:03:51,840 systems 119 00:03:54,949 --> 00:03:53,040 you've got to you've got to really be 120 00:03:56,390 --> 00:03:54,959 careful about what you're doing there so 121 00:03:58,949 --> 00:03:56,400 really i think mission success is going 122 00:04:01,270 --> 00:03:58,959 to depend on effective and very 123 00:04:03,429 --> 00:04:01,280 very very strong risk management 124 00:04:06,070 --> 00:04:03,439 so my message here is that i think that 125 00:04:08,710 --> 00:04:06,080 the industry team both industry academia 126 00:04:10,229 --> 00:04:08,720 and nasa that nasa has 127 00:04:11,509 --> 00:04:10,239 to make a broader 128 00:04:12,789 --> 00:04:11,519 community involvement of this mission i 129 00:04:14,390 --> 00:04:12,799 think will really be a go a long way 130 00:04:15,589 --> 00:04:14,400 towards minimizing that risk 131 00:04:17,749 --> 00:04:15,599 there's an extensive amount of 132 00:04:19,430 --> 00:04:17,759 experience in industry 133 00:04:20,870 --> 00:04:19,440 and from our current production programs 134 00:04:22,790 --> 00:04:20,880 on the commercial side as well as the 135 00:04:25,189 --> 00:04:22,800 the existing nasa programs that can be 136 00:04:26,469 --> 00:04:25,199 used to mitigate risks and i've listed 137 00:04:28,629 --> 00:04:26,479 really five key ones there that i'm 138 00:04:30,550 --> 00:04:28,639 going to talk a bit more about as we go 139 00:04:31,830 --> 00:04:30,560 through the presentation first of all 140 00:04:33,350 --> 00:04:31,840 using flight proven systems high 141 00:04:35,270 --> 00:04:33,360 heritage systems will that as your point 142 00:04:37,350 --> 00:04:35,280 of departure to have definitely reduces 143 00:04:38,790 --> 00:04:37,360 the risk on the system 144 00:04:40,070 --> 00:04:38,800 utilizing a 145 00:04:41,510 --> 00:04:40,080 a prime integrator if you will to 146 00:04:43,430 --> 00:04:41,520 integrate the solar electric propulsion 147 00:04:45,350 --> 00:04:43,440 technologies into the mission i i think 148 00:04:47,909 --> 00:04:45,360 is also has a lot of merit 149 00:04:49,430 --> 00:04:47,919 you can leverage the experience that the 150 00:04:51,510 --> 00:04:49,440 industry partners have 151 00:04:53,510 --> 00:04:51,520 to to get that system integrated and 152 00:04:55,430 --> 00:04:53,520 working right a lot of best practices to 153 00:04:57,430 --> 00:04:55,440 bring to bear 154 00:04:59,510 --> 00:04:57,440 launching on sls really increases your 155 00:05:01,350 --> 00:04:59,520 margins increased margin increases your 156 00:05:05,510 --> 00:05:01,360 uh your ability to handle unforeseen 157 00:05:09,270 --> 00:05:07,189 ben mentioned designing the system for 158 00:05:10,390 --> 00:05:09,280 reuse i think that's a really a really 159 00:05:12,150 --> 00:05:10,400 smart move 160 00:05:14,550 --> 00:05:12,160 it maximizes a return on investment no 161 00:05:16,469 --> 00:05:14,560 matter what you do this even trying to 162 00:05:17,749 --> 00:05:16,479 to drive costs down and be affordable 163 00:05:19,830 --> 00:05:17,759 this is going to be a very expensive 164 00:05:21,670 --> 00:05:19,840 investment for the country so reusing 165 00:05:23,029 --> 00:05:21,680 that system only makes sense and there's 166 00:05:24,469 --> 00:05:23,039 some things you can do early on when you 167 00:05:25,830 --> 00:05:24,479 do the design to to enhance that 168 00:05:27,430 --> 00:05:25,840 reusability 169 00:05:29,749 --> 00:05:27,440 and implement implementing an integrated 170 00:05:31,110 --> 00:05:29,759 gnc system uh into the uh 171 00:05:32,790 --> 00:05:31,120 into the autonomous rendezvous and 172 00:05:33,909 --> 00:05:32,800 docking portion make it all resident in 173 00:05:35,110 --> 00:05:33,919 one vehicle 174 00:05:36,469 --> 00:05:35,120 we think there's some real benefits to 175 00:05:39,189 --> 00:05:36,479 that many probably touch on that but in 176 00:05:40,469 --> 00:05:39,199 terms of testing seamless 177 00:05:41,830 --> 00:05:40,479 seams 178 00:05:45,670 --> 00:05:41,840 interface requirements of that type of 179 00:05:46,469 --> 00:05:45,680 thing it seems like a smarter way to go 180 00:05:48,310 --> 00:05:46,479 so 181 00:05:51,350 --> 00:05:48,320 the first topic heritage systems 182 00:05:53,510 --> 00:05:51,360 reducing development execution risk 183 00:05:57,270 --> 00:05:53,520 there's a lot of uh spacecraft knowledge 184 00:05:58,870 --> 00:05:57,280 uh in america in the industry uh we've 185 00:06:01,110 --> 00:05:58,880 we've been uh you know we produce 186 00:06:02,629 --> 00:06:01,120 spacecraft for it well basically entire 187 00:06:05,990 --> 00:06:02,639 industries depend on the spacecraft that 188 00:06:07,189 --> 00:06:06,000 we produce for example xm radio 189 00:06:08,870 --> 00:06:07,199 directv 190 00:06:10,309 --> 00:06:08,880 so the reliability 191 00:06:12,230 --> 00:06:10,319 and mission success requirements on 192 00:06:13,749 --> 00:06:12,240 those types of platforms 193 00:06:15,270 --> 00:06:13,759 are you know they're equally as 194 00:06:17,350 --> 00:06:15,280 important as they are for a mission of 195 00:06:18,710 --> 00:06:17,360 this magnitude as well so you've got a 196 00:06:20,870 --> 00:06:18,720 lot of flight proven design and 197 00:06:22,950 --> 00:06:20,880 qualification experience that a resident 198 00:06:24,309 --> 00:06:22,960 in the industry partners 199 00:06:26,309 --> 00:06:24,319 very established and repeatable 200 00:06:27,990 --> 00:06:26,319 processes and tools and and the 201 00:06:31,430 --> 00:06:28,000 personnel who know how to build these 202 00:06:32,870 --> 00:06:31,440 platforms that's a real key 203 00:06:35,029 --> 00:06:32,880 benefit that that could be brought to 204 00:06:37,189 --> 00:06:35,039 bear here on this on this program 205 00:06:38,309 --> 00:06:37,199 of integrated and well-exercised supply 206 00:06:39,990 --> 00:06:38,319 chain 207 00:06:41,749 --> 00:06:40,000 even though you're going to build just 208 00:06:43,990 --> 00:06:41,759 maybe one vehicle for this particular 209 00:06:45,590 --> 00:06:44,000 mission if you need spare parts you you 210 00:06:47,189 --> 00:06:45,600 have to do some some testing something 211 00:06:48,790 --> 00:06:47,199 that you hadn't foreseen if you can pull 212 00:06:50,550 --> 00:06:48,800 in that supply chain to get those parts 213 00:06:52,629 --> 00:06:50,560 or build up an engineering design unit 214 00:06:54,710 --> 00:06:52,639 and pretty quick time 215 00:06:56,469 --> 00:06:54,720 that's a real benefit as well 216 00:06:58,870 --> 00:06:56,479 once again 15-year lifetime for most of 217 00:07:02,309 --> 00:06:58,880 the commercial geocom platforms that are 218 00:07:03,990 --> 00:07:02,319 built out there if not longer 219 00:07:06,070 --> 00:07:04,000 operational envelopes and limits we know 220 00:07:08,790 --> 00:07:06,080 what the the space vehicle is designed 221 00:07:10,710 --> 00:07:08,800 for and and we've tested that and we see 222 00:07:12,550 --> 00:07:10,720 it happen in real in operational 223 00:07:13,909 --> 00:07:12,560 experience so we know how the vehicle is 224 00:07:15,270 --> 00:07:13,919 going to operate 225 00:07:17,990 --> 00:07:15,280 established launch vehicle and payload 226 00:07:19,670 --> 00:07:18,000 interfaces up to ten thousand kilogram 227 00:07:21,270 --> 00:07:19,680 uh payloads can be accommodated on most 228 00:07:23,029 --> 00:07:21,280 of these platforms i know adam said that 229 00:07:25,029 --> 00:07:23,039 the laurel platform can go a little bit 230 00:07:26,550 --> 00:07:25,039 higher so more mass is going to be you 231 00:07:28,309 --> 00:07:26,560 know that gives you that margin that 232 00:07:30,070 --> 00:07:28,319 you're going to need to be successful 233 00:07:31,670 --> 00:07:30,080 uh and you know you uh as you're 234 00:07:33,589 --> 00:07:31,680 designing the mission uh depending on 235 00:07:35,110 --> 00:07:33,599 the trades that say been alluded to 236 00:07:37,270 --> 00:07:35,120 whether you do a two-piece spacecraft or 237 00:07:39,029 --> 00:07:37,280 a monolithic spacecraft you can you can 238 00:07:41,350 --> 00:07:39,039 draw on the industries either their 239 00:07:43,270 --> 00:07:41,360 system subsystems or the entire platform 240 00:07:46,070 --> 00:07:43,280 for a turnkey solution 241 00:07:47,909 --> 00:07:46,080 it gives flexibility to nasa and really 242 00:07:49,029 --> 00:07:47,919 what that does it allows nasa to focus 243 00:07:51,029 --> 00:07:49,039 on the hard things that need to be 244 00:07:53,029 --> 00:07:51,039 developed the spacecraft's going to be 245 00:07:54,869 --> 00:07:53,039 it'll be a tough engineering challenge 246 00:07:57,110 --> 00:07:54,879 but getting those technologies done and 247 00:07:58,230 --> 00:07:57,120 getting them validated trl 6 and above 248 00:08:00,710 --> 00:07:58,240 in the time frame that we're talking 249 00:08:05,510 --> 00:08:00,720 about that's a big job and that way the 250 00:08:05,520 --> 00:08:10,950 i didn't do that i did not do that 251 00:08:15,430 --> 00:08:12,469 i'm not going to update firefox right 252 00:08:23,510 --> 00:08:16,790 okay 253 00:08:24,950 --> 00:08:23,520 chart 254 00:08:27,749 --> 00:08:24,960 uh integration experience for solar 255 00:08:29,430 --> 00:08:27,759 electric propulsion technologies 256 00:08:33,110 --> 00:08:29,440 there are lots of uh 257 00:08:33,990 --> 00:08:33,120 lots lots of uh use of scp in in today's 258 00:08:36,149 --> 00:08:34,000 uh 259 00:08:37,430 --> 00:08:36,159 geocom and other applications space 260 00:08:38,949 --> 00:08:37,440 mission markets 261 00:08:40,389 --> 00:08:38,959 um a lot you know with the advanced 262 00:08:42,149 --> 00:08:40,399 solar echo propulsion that's been talked 263 00:08:44,310 --> 00:08:42,159 about for this mission is quite a leap 264 00:08:45,910 --> 00:08:44,320 in terms of power both for the thrusters 265 00:08:47,030 --> 00:08:45,920 and for the solar rays but there's a lot 266 00:08:49,190 --> 00:08:47,040 of uh 267 00:08:51,110 --> 00:08:49,200 there's there's over many many years of 268 00:08:53,110 --> 00:08:51,120 operational experience out there 269 00:08:55,190 --> 00:08:53,120 operating these systems 270 00:08:57,829 --> 00:08:55,200 doing you know station keeping a geo or 271 00:08:59,269 --> 00:08:57,839 in the uh in the context of the vehicle 272 00:09:02,389 --> 00:08:59,279 that boeing has recently developed at 273 00:09:04,389 --> 00:09:02,399 702 sp it actually uses the uh 274 00:09:05,990 --> 00:09:04,399 the solar propulsion to actually to 275 00:09:07,350 --> 00:09:06,000 orbit raise now granted it takes a 276 00:09:09,030 --> 00:09:07,360 little bit longer to get on station but 277 00:09:10,949 --> 00:09:09,040 it really reduces your launch costs 278 00:09:12,310 --> 00:09:10,959 which is a real benefit point is there's 279 00:09:14,630 --> 00:09:12,320 a lot of experience on how to integrate 280 00:09:16,310 --> 00:09:14,640 step technology into into systems at an 281 00:09:17,269 --> 00:09:16,320 industry that could be applied here for 282 00:09:18,470 --> 00:09:17,279 nasa 283 00:09:19,829 --> 00:09:18,480 um 284 00:09:21,750 --> 00:09:19,839 lots of lessons learned from our 285 00:09:23,910 --> 00:09:21,760 experience in both production design and 286 00:09:26,150 --> 00:09:23,920 operations once again solid supplier 287 00:09:27,990 --> 00:09:26,160 relationships with with all the key 288 00:09:29,350 --> 00:09:28,000 producers 289 00:09:32,150 --> 00:09:29,360 some firms have indigenous solar 290 00:09:34,470 --> 00:09:32,160 reproduction tests and 291 00:09:36,870 --> 00:09:34,480 build facilities and capabilities that 292 00:09:39,110 --> 00:09:36,880 could be brought in state-of-the-art 293 00:09:40,550 --> 00:09:39,120 test equipment also exists 294 00:09:42,470 --> 00:09:40,560 once again the experience base is you 295 00:09:44,710 --> 00:09:42,480 know for for boeing anyhow it's well 296 00:09:47,030 --> 00:09:44,720 over 90 years of operational experience 297 00:09:48,790 --> 00:09:47,040 with step powered uh vehicles 298 00:09:51,030 --> 00:09:48,800 and there's you know the the ability to 299 00:09:52,870 --> 00:09:51,040 do low thrust trajectory design 300 00:09:55,110 --> 00:09:52,880 mission planning and the navigation 301 00:09:57,509 --> 00:09:55,120 expertise with that is also becoming 302 00:09:58,870 --> 00:09:57,519 more important and that can add to the 303 00:10:02,230 --> 00:09:58,880 mission success 304 00:10:07,829 --> 00:10:04,710 uh sls what a great asset to have for 305 00:10:09,750 --> 00:10:07,839 this mission um nasa is building the sls 306 00:10:12,230 --> 00:10:09,760 now uh they're actually ahead of 307 00:10:15,030 --> 00:10:12,240 schedule in many instances uh vehicles 308 00:10:16,190 --> 00:10:15,040 on on track to you know fly 309 00:10:19,030 --> 00:10:16,200 in the 310 00:10:20,630 --> 00:10:19,040 2017-2018 time frame 311 00:10:22,790 --> 00:10:20,640 that's really a 312 00:10:24,949 --> 00:10:22,800 fortuitous schedule coincidence that if 313 00:10:26,710 --> 00:10:24,959 you can launch on sls basically you get 314 00:10:28,630 --> 00:10:26,720 you get more mass 315 00:10:29,990 --> 00:10:28,640 you get you could possibly you 316 00:10:31,509 --> 00:10:30,000 demonstrate a gravity tractor 317 00:10:33,750 --> 00:10:31,519 demonstration deflection demonstration 318 00:10:36,150 --> 00:10:33,760 if you have a massive enough spacecraft 319 00:10:37,910 --> 00:10:36,160 you can launch on a direct injection 320 00:10:39,590 --> 00:10:37,920 trajectory to lunar gravity assist or 321 00:10:41,750 --> 00:10:39,600 straight to the target depending on what 322 00:10:43,190 --> 00:10:41,760 the target is it eliminates that spiral 323 00:10:44,790 --> 00:10:43,200 out phase and saves you about two years 324 00:10:46,310 --> 00:10:44,800 on the overall mission duration or one 325 00:10:47,990 --> 00:10:46,320 to three years depending on once again 326 00:10:50,470 --> 00:10:48,000 where you're going and how big it is 327 00:10:52,069 --> 00:10:50,480 but the additional sep technology 328 00:10:53,750 --> 00:10:52,079 technology maturation schedule that the 329 00:10:54,630 --> 00:10:53,760 sls provides i think is a real benefit 330 00:10:56,949 --> 00:10:54,640 too 331 00:10:57,670 --> 00:10:56,959 if we push back the notion launch date 332 00:10:59,590 --> 00:10:57,680 two 333 00:11:01,590 --> 00:10:59,600 when sls is flying a block block one 334 00:11:03,430 --> 00:11:01,600 configuration once again that gives 335 00:11:05,670 --> 00:11:03,440 the technology folks a little bit extra 336 00:11:07,750 --> 00:11:05,680 time to get the uh to get the step up to 337 00:11:09,190 --> 00:11:07,760 the right trl and a little bit of extra 338 00:11:14,069 --> 00:11:09,200 schedule margin is always good when 339 00:11:18,630 --> 00:11:16,150 designing for usability also maximizes 340 00:11:19,590 --> 00:11:18,640 the return of investment for nasa 341 00:11:20,870 --> 00:11:19,600 um 342 00:11:22,630 --> 00:11:20,880 after the 343 00:11:24,389 --> 00:11:22,640 asteroid retrieval mission is complete 344 00:11:26,069 --> 00:11:24,399 there's probably still 345 00:11:28,389 --> 00:11:26,079 five to ten years of remaining lifetime 346 00:11:30,230 --> 00:11:28,399 on the vehicle if not more 347 00:11:34,150 --> 00:11:30,240 you've got 50 kilowatts at beginning of 348 00:11:35,670 --> 00:11:34,160 life on station and translunar space now 349 00:11:38,150 --> 00:11:35,680 what a great asset once again to have 350 00:11:39,750 --> 00:11:38,160 for any future exploration architecture 351 00:11:41,590 --> 00:11:39,760 pieces that come out there 352 00:11:42,550 --> 00:11:41,600 that either need a tug or just a power 353 00:11:44,470 --> 00:11:42,560 supply 354 00:11:47,030 --> 00:11:44,480 or a lot of the other capabilities that 355 00:11:48,630 --> 00:11:47,040 the arm will have inherent in its design 356 00:11:50,949 --> 00:11:48,640 you could also refuel it if you designed 357 00:11:52,310 --> 00:11:50,959 that early on that once again sls can 358 00:11:54,550 --> 00:11:52,320 bring up quite a large quantity 359 00:11:57,030 --> 00:11:54,560 propellant to translunar space to refuel 360 00:11:57,990 --> 00:11:57,040 it or if it during the operational mode 361 00:11:59,670 --> 00:11:58,000 it can get back to earth you could 362 00:12:00,949 --> 00:11:59,680 refuel it even closer 363 00:12:02,389 --> 00:12:00,959 but there's a lot of applications that 364 00:12:03,910 --> 00:12:02,399 you could have there so 365 00:12:04,790 --> 00:12:03,920 thinking about it in terms of reuses 366 00:12:06,310 --> 00:12:04,800 should be 367 00:12:10,470 --> 00:12:06,320 one of the guiding principles in terms 368 00:12:13,829 --> 00:12:10,480 of the system engineering early on 369 00:12:16,389 --> 00:12:13,839 and integrated autonomous rendezvous 370 00:12:17,990 --> 00:12:16,399 capabilities into the overall spacecraft 371 00:12:20,310 --> 00:12:18,000 simplifies the design and operations of 372 00:12:22,069 --> 00:12:20,320 the mission the integrated system that 373 00:12:24,150 --> 00:12:22,079 has both air and d and terrain relative 374 00:12:25,750 --> 00:12:24,160 navigation sensors on it we feel is the 375 00:12:28,790 --> 00:12:25,760 lowest risk approach and having those 376 00:12:31,110 --> 00:12:28,800 integrated into the the flight system 377 00:12:32,550 --> 00:12:31,120 it basically decouples the the arnd 378 00:12:34,389 --> 00:12:32,560 stuff 379 00:12:36,829 --> 00:12:34,399 which is very relatively mature from the 380 00:12:39,829 --> 00:12:36,839 new the new technology propulsion 381 00:12:41,269 --> 00:12:39,839 development better integrates the gnc 382 00:12:42,790 --> 00:12:41,279 system performance overall because you 383 00:12:44,470 --> 00:12:42,800 don't have two interfaces you don't have 384 00:12:45,750 --> 00:12:44,480 two computers talking to each other 385 00:12:47,590 --> 00:12:45,760 streamlines the 386 00:12:49,670 --> 00:12:47,600 getting ready to fly simplifies 387 00:12:51,190 --> 00:12:49,680 interfaces and 388 00:12:54,069 --> 00:12:51,200 potentially you could use the sensors to 389 00:12:55,509 --> 00:12:54,079 do both both the the the tracking far 390 00:12:56,710 --> 00:12:55,519 away and in 391 00:12:58,790 --> 00:12:56,720 close 392 00:13:00,069 --> 00:12:58,800 and with that i will turn that over to 393 00:13:01,509 --> 00:13:00,079 manny and let him tell you a little bit 394 00:13:14,870 --> 00:13:01,519 more about 395 00:13:19,110 --> 00:13:16,790 okay so 396 00:13:20,949 --> 00:13:19,120 quickly 397 00:13:23,350 --> 00:13:20,959 we have the experience from the orbital 398 00:13:26,710 --> 00:13:23,360 express program back in 2007 of having 399 00:13:28,470 --> 00:13:26,720 flown optical navigation systems uh 400 00:13:29,750 --> 00:13:28,480 there's a picture of what we flew back 401 00:13:32,230 --> 00:13:29,760 in uh 402 00:13:35,350 --> 00:13:32,240 back back there six six years ago on 403 00:13:36,949 --> 00:13:35,360 board the astro spacecraft completed uh 404 00:13:39,269 --> 00:13:36,959 six autonomous rendezvous and docking 405 00:13:40,710 --> 00:13:39,279 scenarios uh and 406 00:13:43,030 --> 00:13:40,720 one point here which is not that 407 00:13:45,910 --> 00:13:43,040 commonly known although we use the 408 00:13:47,590 --> 00:13:45,920 nasa avgs system for corridor approach 409 00:13:50,790 --> 00:13:47,600 actually all the acquisition and track 410 00:13:52,790 --> 00:13:50,800 was using optical navigation from 411 00:13:53,990 --> 00:13:52,800 hundreds of kilometers on 412 00:13:55,790 --> 00:13:54,000 all the way in 413 00:13:58,150 --> 00:13:55,800 to capture 414 00:13:59,990 --> 00:13:58,160 contemporaneously with the the nasa 415 00:14:01,509 --> 00:14:00,000 system so just wanted to get that out 416 00:14:03,590 --> 00:14:01,519 there to make sure everybody under 417 00:14:04,550 --> 00:14:03,600 understands that so fast forward to 418 00:14:06,710 --> 00:14:04,560 today 419 00:14:08,389 --> 00:14:06,720 we have two different systems that uh 420 00:14:10,470 --> 00:14:08,399 one one in particular that we are 421 00:14:13,269 --> 00:14:10,480 developing for flight that being for 422 00:14:15,030 --> 00:14:13,279 commercial crew we call that vesta 423 00:14:16,710 --> 00:14:15,040 that is allowing us to do completely 424 00:14:19,189 --> 00:14:16,720 autonomous rendezvous 425 00:14:20,150 --> 00:14:19,199 and and docking 426 00:14:22,150 --> 00:14:20,160 we see 427 00:14:25,430 --> 00:14:22,160 really good applicability of a similar 428 00:14:28,870 --> 00:14:25,440 system for uh for uh asteroid and 429 00:14:31,110 --> 00:14:28,880 planetary type type missions as well so 430 00:14:32,470 --> 00:14:31,120 kind of put together sort of a notional 431 00:14:33,910 --> 00:14:32,480 con ops here and i don't have time to 432 00:14:36,550 --> 00:14:33,920 brief this in 433 00:14:39,430 --> 00:14:36,560 in detail but uh probably one of the 434 00:14:41,110 --> 00:14:39,440 important takeaways here is that uh so 435 00:14:42,829 --> 00:14:41,120 first of all a lot of similarity in our 436 00:14:43,829 --> 00:14:42,839 thinking in in 437 00:14:45,750 --> 00:14:43,839 terms and 438 00:14:48,470 --> 00:14:45,760 from what john brophy was saying earlier 439 00:14:50,230 --> 00:14:48,480 in terms of visible sensors and and 440 00:14:51,910 --> 00:14:50,240 ladar type sensors 441 00:14:53,670 --> 00:14:51,920 definitely having something that gives 442 00:14:56,310 --> 00:14:53,680 you long range track 443 00:14:59,350 --> 00:14:56,320 really good precision 444 00:15:01,590 --> 00:14:59,360 vision and feature identification in 445 00:15:04,230 --> 00:15:01,600 in sunlight is is excellent and the 446 00:15:06,389 --> 00:15:04,240 lidar sensor to give you range and and 447 00:15:08,790 --> 00:15:06,399 3d shape very important the thing we'd 448 00:15:10,389 --> 00:15:08,800 like to add into the mix there is long 449 00:15:12,069 --> 00:15:10,399 wave infrared 450 00:15:14,310 --> 00:15:12,079 i think we were among the first if not 451 00:15:16,710 --> 00:15:14,320 the first to fly an lwir sensor on 452 00:15:18,470 --> 00:15:16,720 orbital express and since then uh lots 453 00:15:20,310 --> 00:15:18,480 of folks are using them for autonomous 454 00:15:23,110 --> 00:15:20,320 rendezvous we'd like to throw that in 455 00:15:24,550 --> 00:15:23,120 here as as a suggestion for 456 00:15:26,470 --> 00:15:24,560 uh for 457 00:15:28,870 --> 00:15:26,480 this mission arm as well 458 00:15:30,629 --> 00:15:28,880 the the thing that that brings to you is 459 00:15:33,749 --> 00:15:30,639 is really good solar immunity sun 460 00:15:35,990 --> 00:15:33,759 immunity and uh ability to see in uh 461 00:15:38,230 --> 00:15:36,000 into dark shadows uh so it helps with 462 00:15:39,590 --> 00:15:38,240 shape determination so if you look 463 00:15:41,749 --> 00:15:39,600 through this you know using visible 464 00:15:43,829 --> 00:15:41,759 sensors to acquire at long range and 465 00:15:46,550 --> 00:15:43,839 then coming on stepping on in and then 466 00:15:48,949 --> 00:15:46,560 using these disparate sensors fusing the 467 00:15:50,870 --> 00:15:48,959 data to do the asteroid characterization 468 00:15:53,670 --> 00:15:50,880 tasks and and then to support the 469 00:15:55,030 --> 00:15:53,680 capture the d spin and then also the 470 00:15:56,790 --> 00:15:55,040 capability of 471 00:15:59,189 --> 00:15:56,800 of dual use on these sensors for 472 00:16:01,189 --> 00:15:59,199 inertial nav uh versus uh versus 473 00:16:03,350 --> 00:16:01,199 relative nav 474 00:16:06,069 --> 00:16:03,360 and just a quick one on the on the 475 00:16:07,350 --> 00:16:06,079 benefits uh i think i said some of this 476 00:16:08,310 --> 00:16:07,360 as to why 477 00:16:10,470 --> 00:16:08,320 a long 478 00:16:12,550 --> 00:16:10,480 long range or long wave infrared camera 479 00:16:13,590 --> 00:16:12,560 is uh is good and i think gosh i 480 00:16:16,150 --> 00:16:13,600 finished weight i feel like it's 481 00:16:17,110 --> 00:16:16,160 something else i should have said 482 00:16:18,949 --> 00:16:17,120 all right 483 00:16:20,629 --> 00:16:18,959 we have time for a question but well 484 00:16:22,230 --> 00:16:20,639 thank you and again 485 00:16:24,069 --> 00:16:22,240 we don't have type of questions so we'll 486 00:16:31,110 --> 00:16:24,079 catch them at the end 487 00:16:37,030 --> 00:16:34,230 all right we're cooking right along here 488 00:16:38,790 --> 00:16:37,040 our next speaker is john ringelberg he's 489 00:16:40,230 --> 00:16:38,800 a senior staff engineer at lockheed 490 00:16:41,829 --> 00:16:40,240 martin denver 491 00:16:43,749 --> 00:16:41,839 working in the civil space advanced 492 00:16:45,509 --> 00:16:43,759 programs group he's the principal 493 00:16:47,269 --> 00:16:45,519 investigator for an irat effort 494 00:16:49,670 --> 00:16:47,279 advancing autonomous rendezvous 495 00:16:51,430 --> 00:16:49,680 proximity operations docking and landing 496 00:16:52,870 --> 00:16:51,440 technologies 497 00:16:54,949 --> 00:16:52,880 his presentation will provide an 498 00:16:56,629 --> 00:16:54,959 overview of integrated sensing systems 499 00:16:58,470 --> 00:16:56,639 from previous missions with direct 500 00:17:00,470 --> 00:16:58,480 correlation to arm 501 00:17:02,150 --> 00:17:00,480 particular technologies for asteroid 502 00:17:03,990 --> 00:17:02,160 relative nav and characterization will 503 00:17:05,750 --> 00:17:04,000 be highlighted and a brief summary of 504 00:17:08,390 --> 00:17:05,760 solar electric propulsion heritage and 505 00:17:11,270 --> 00:17:08,400 technology will also be provided 506 00:17:12,309 --> 00:17:11,280 thanks john thanks um continuing on that 507 00:17:14,549 --> 00:17:12,319 theme 508 00:17:16,870 --> 00:17:14,559 kind of the last few presentations of 509 00:17:18,549 --> 00:17:16,880 trying to leverage uh 510 00:17:20,789 --> 00:17:18,559 some of the work that's been done on 511 00:17:21,909 --> 00:17:20,799 either previous programs or on current 512 00:17:26,630 --> 00:17:21,919 programs 513 00:17:28,390 --> 00:17:26,640 is osiris-rex which is 514 00:17:30,830 --> 00:17:28,400 which is a mission 515 00:17:33,350 --> 00:17:30,840 lockheed has a strong role in but uh 516 00:17:34,630 --> 00:17:33,360 goddard leading this 517 00:17:36,070 --> 00:17:34,640 there's a lot of things that are being 518 00:17:38,470 --> 00:17:36,080 done on on 519 00:17:40,390 --> 00:17:38,480 osiris-rex that probably are very 520 00:17:42,230 --> 00:17:40,400 applicable to 521 00:17:44,070 --> 00:17:42,240 what's what's going to happen for what 522 00:17:45,190 --> 00:17:44,080 you need to do for the asteroid redirect 523 00:17:47,110 --> 00:17:45,200 mission 524 00:17:49,270 --> 00:17:47,120 there's particular areas that 525 00:17:51,430 --> 00:17:49,280 that it's a much bigger asteroid that 526 00:17:53,669 --> 00:17:51,440 osiris-rex is going to 527 00:17:55,350 --> 00:17:53,679 they're going to have a lot more time 528 00:17:57,669 --> 00:17:55,360 most likely 529 00:17:59,909 --> 00:17:57,679 station keeping 530 00:18:01,190 --> 00:17:59,919 mapping and characterizing the asteroid 531 00:18:02,870 --> 00:18:01,200 but there's still a lot of the 532 00:18:05,110 --> 00:18:02,880 capabilities particularly that are going 533 00:18:06,549 --> 00:18:05,120 into a size 4x that you can extend and 534 00:18:09,590 --> 00:18:06,559 apply to 535 00:18:11,909 --> 00:18:09,600 the asteroid redirect mission 536 00:18:14,470 --> 00:18:11,919 both both optical and and what was 537 00:18:16,310 --> 00:18:14,480 mentioned earlier lidar lidar usage for 538 00:18:17,590 --> 00:18:16,320 for osiris-rex and mapping there's 539 00:18:19,110 --> 00:18:17,600 there's there's 540 00:18:21,110 --> 00:18:19,120 some areas particularly for the optical 541 00:18:24,390 --> 00:18:21,120 navigation that we're doing some work 542 00:18:26,950 --> 00:18:24,400 that can improve the the resolution for 543 00:18:28,630 --> 00:18:26,960 or the accuracy for your targeting for 544 00:18:30,950 --> 00:18:28,640 what osiris-rex does which is the 545 00:18:32,549 --> 00:18:30,960 approach and sample capture contact and 546 00:18:34,230 --> 00:18:32,559 sample capture 547 00:18:35,430 --> 00:18:34,240 that's extensible whether it's whether 548 00:18:37,669 --> 00:18:35,440 it's the uh 549 00:18:39,430 --> 00:18:37,679 the bag capture or like a more of a 550 00:18:41,110 --> 00:18:39,440 robotic capture a close close-in 551 00:18:43,110 --> 00:18:41,120 approach such as that that ben talked 552 00:18:45,350 --> 00:18:43,120 about 553 00:18:48,950 --> 00:18:45,360 another mission 554 00:18:50,870 --> 00:18:48,960 further in the past but similar 555 00:18:53,029 --> 00:18:50,880 type operations 556 00:18:54,870 --> 00:18:53,039 wanted to mention the xss-11 mission 557 00:18:56,390 --> 00:18:54,880 which most of you probably are familiar 558 00:18:59,270 --> 00:18:56,400 with maybe not everybody but this 559 00:19:02,710 --> 00:18:59,280 mission was a afro mission 560 00:19:05,029 --> 00:19:02,720 very successful didn't do capture or 561 00:19:06,870 --> 00:19:05,039 contact but did a lot of proximity 562 00:19:08,870 --> 00:19:06,880 operations 563 00:19:10,950 --> 00:19:08,880 with with different non-cooperative 564 00:19:14,150 --> 00:19:10,960 targets and that's one of the key things 565 00:19:15,909 --> 00:19:14,160 that i wanted to point out here was 566 00:19:17,830 --> 00:19:15,919 what the asteroid redirect mission is 567 00:19:19,430 --> 00:19:17,840 going to do there's there's a need for 568 00:19:21,750 --> 00:19:19,440 being able to go up something you know 569 00:19:23,110 --> 00:19:21,760 almost nothing about you don't know the 570 00:19:24,630 --> 00:19:23,120 surface features you don't know it's 571 00:19:26,070 --> 00:19:24,640 spin rates you don't know how it's 572 00:19:29,430 --> 00:19:26,080 moving 573 00:19:31,590 --> 00:19:29,440 so missions like this 574 00:19:33,830 --> 00:19:31,600 lessons learned from that and work since 575 00:19:35,909 --> 00:19:33,840 that can be used to apply for going up 576 00:19:37,590 --> 00:19:35,919 to a non-cooperative target 577 00:19:39,510 --> 00:19:37,600 performing proximity operations 578 00:19:41,990 --> 00:19:39,520 characterizing and the other part of it 579 00:19:44,470 --> 00:19:42,000 is is the safe operations and proximity 580 00:19:45,909 --> 00:19:44,480 to to your target making sure your 581 00:19:48,549 --> 00:19:45,919 there was there was a lot of work done 582 00:19:51,350 --> 00:19:48,559 on this that that was 583 00:19:54,230 --> 00:19:51,360 a good bit of autonomous where it had to 584 00:19:56,070 --> 00:19:54,240 plan your maneuvers ahead of time on how 585 00:19:57,909 --> 00:19:56,080 what's your natural motion and force 586 00:20:00,070 --> 00:19:57,919 motion well for the for the asteroid 587 00:20:01,590 --> 00:20:00,080 mission for force motion circumnav 588 00:20:03,029 --> 00:20:01,600 around where on your target how are you 589 00:20:06,549 --> 00:20:03,039 going to do that safely how you plan 590 00:20:08,310 --> 00:20:06,559 ahead and this being so far out 591 00:20:11,110 --> 00:20:08,320 using using things you've done in the 592 00:20:13,029 --> 00:20:11,120 past to be able to build on those and do 593 00:20:15,110 --> 00:20:13,039 your safe operations in close proximity 594 00:20:17,590 --> 00:20:15,120 to a target that's so far away that you 595 00:20:20,950 --> 00:20:17,600 don't have may not have the continuous 596 00:20:22,549 --> 00:20:20,960 communication with 597 00:20:24,070 --> 00:20:22,559 another area that that we've been 598 00:20:26,789 --> 00:20:24,080 working on um 599 00:20:29,029 --> 00:20:26,799 kind of extensive extensible to this 600 00:20:31,190 --> 00:20:29,039 doing different irad and c-rad work 601 00:20:33,270 --> 00:20:31,200 we've we've done um 602 00:20:35,990 --> 00:20:33,280 is is particularly with the optical nav 603 00:20:38,549 --> 00:20:36,000 that was mentioned earlier as as 604 00:20:40,789 --> 00:20:38,559 one of the key features that's needed 605 00:20:43,590 --> 00:20:40,799 for approaching 606 00:20:46,149 --> 00:20:43,600 the asteroid whatever the arm target is 607 00:20:48,310 --> 00:20:46,159 we've done a lot of work in this area 608 00:20:50,070 --> 00:20:48,320 there's also a lot of other areas other 609 00:20:51,350 --> 00:20:50,080 people doing work in this area but we're 610 00:20:53,029 --> 00:20:51,360 kind of advancing this is something 611 00:20:55,830 --> 00:20:53,039 that's probably going to help out 612 00:20:56,870 --> 00:20:55,840 osiris-rex to some extent as far as the 613 00:20:59,190 --> 00:20:56,880 precision 614 00:21:01,430 --> 00:20:59,200 approach capability 615 00:21:03,270 --> 00:21:01,440 but using natural feature tracking to to 616 00:21:05,510 --> 00:21:03,280 map the surface 617 00:21:11,909 --> 00:21:05,520 and to plan out your approach for the 618 00:21:15,590 --> 00:21:13,190 another area 619 00:21:17,510 --> 00:21:15,600 our coherent technologies area 620 00:21:18,710 --> 00:21:17,520 disciplines a lot of work on the the 621 00:21:20,870 --> 00:21:18,720 laser 622 00:21:23,990 --> 00:21:20,880 or lidar type 623 00:21:25,350 --> 00:21:24,000 mapping and characterization uh 624 00:21:27,750 --> 00:21:25,360 two different methods we mentioned in 625 00:21:30,470 --> 00:21:27,760 the nrfi response 626 00:21:32,470 --> 00:21:30,480 that can be combined for particularly 627 00:21:34,710 --> 00:21:32,480 used for characterizing asteroids so you 628 00:21:35,669 --> 00:21:34,720 understand it for for the approach 629 00:21:37,669 --> 00:21:35,679 and and 630 00:21:39,350 --> 00:21:37,679 and capture part of it digital 631 00:21:41,510 --> 00:21:39,360 holographic imaging 632 00:21:43,909 --> 00:21:41,520 gives you some work we've done we've 633 00:21:45,270 --> 00:21:43,919 tested out coherent our coherent group 634 00:21:47,190 --> 00:21:45,280 does a lot of work on the terrestrial 635 00:21:48,549 --> 00:21:47,200 but also applying at the space 636 00:21:50,390 --> 00:21:48,559 applications 637 00:21:52,149 --> 00:21:50,400 um using that that's going to be 638 00:21:54,470 --> 00:21:52,159 important to characterize the asteroid 639 00:21:56,390 --> 00:21:54,480 as as you approach it and to understand 640 00:21:57,270 --> 00:21:56,400 what its motions are before you capture 641 00:22:00,230 --> 00:21:57,280 it 642 00:22:02,630 --> 00:22:00,240 another another area is the polar metric 643 00:22:04,230 --> 00:22:02,640 sensing hardware to say for asteroid 644 00:22:05,669 --> 00:22:04,240 composition mass you're going to need to 645 00:22:07,270 --> 00:22:05,679 understand the surface before you go up 646 00:22:09,190 --> 00:22:07,280 and grab it you're going to want to 647 00:22:11,350 --> 00:22:09,200 understand that anyway depending on what 648 00:22:13,669 --> 00:22:11,360 your which your capture and grab hold of 649 00:22:15,270 --> 00:22:13,679 technique is that whether that's robotic 650 00:22:17,029 --> 00:22:15,280 particularly if it's robotic you're 651 00:22:19,029 --> 00:22:17,039 going to understand that surface to the 652 00:22:23,990 --> 00:22:19,039 greatest extent possible before you try 653 00:22:27,029 --> 00:22:25,590 and then i also wanted to mention here 654 00:22:29,510 --> 00:22:27,039 um some of you familiar with there's a 655 00:22:32,230 --> 00:22:29,520 facility we have in denver called our 656 00:22:34,630 --> 00:22:32,240 space operation simulation center 657 00:22:36,789 --> 00:22:34,640 this is a large facility and that's not 658 00:22:37,669 --> 00:22:36,799 a real asteroid inside the sosc but it's 659 00:22:44,789 --> 00:22:37,679 a 660 00:22:46,870 --> 00:22:44,799 the need to 661 00:22:48,310 --> 00:22:46,880 if it helps the mission you could put an 662 00:22:50,470 --> 00:22:48,320 asteroid mounted 663 00:22:54,230 --> 00:22:50,480 inside there that's a seven meter 664 00:22:55,830 --> 00:22:54,240 correlated to the size of the ssc but 665 00:22:57,750 --> 00:22:55,840 that's going to be a key part i think of 666 00:22:58,870 --> 00:22:57,760 this mission kind of reducing the risk 667 00:23:01,029 --> 00:22:58,880 of some of the 668 00:23:03,510 --> 00:23:01,039 the technologies that make this a 669 00:23:05,909 --> 00:23:03,520 difficult mission how can you 670 00:23:07,909 --> 00:23:05,919 you want to ground test them in the best 671 00:23:11,110 --> 00:23:07,919 environment possible or most realistic 672 00:23:14,149 --> 00:23:11,120 flight like environment is possible so 673 00:23:17,190 --> 00:23:14,159 using facilities like sosc to test out 674 00:23:19,110 --> 00:23:17,200 those technologies for for the robotic 675 00:23:23,510 --> 00:23:19,120 mission to the asteroid approach and 676 00:23:28,390 --> 00:23:25,750 one thing i 677 00:23:29,909 --> 00:23:28,400 in our rfi response we covered the the 678 00:23:32,230 --> 00:23:29,919 sensing systems 679 00:23:34,230 --> 00:23:32,240 primarily and i wanted to focus on that 680 00:23:37,110 --> 00:23:34,240 during the few minutes here 681 00:23:38,630 --> 00:23:37,120 but also we we discussed scp a little 682 00:23:41,269 --> 00:23:38,640 bit at um 683 00:23:43,510 --> 00:23:41,279 um brian dempsey a guy at lockheed 684 00:23:45,669 --> 00:23:43,520 martin did our input for that rfi 685 00:23:47,269 --> 00:23:45,679 response and really we kind of covered 686 00:23:48,870 --> 00:23:47,279 what's already been covered some of the 687 00:23:51,110 --> 00:23:48,880 other presentations here the four key 688 00:23:53,590 --> 00:23:51,120 areas that need to be 689 00:23:55,669 --> 00:23:53,600 addressed to make to enable the scp for 690 00:23:57,350 --> 00:23:55,679 for this mission um thrusters the hall 691 00:23:59,430 --> 00:23:57,360 current thrusters 692 00:24:01,669 --> 00:23:59,440 seems to be the focus for most everyone 693 00:24:04,710 --> 00:24:01,679 here that's provide good 694 00:24:06,390 --> 00:24:04,720 high power to thrust to power ratio 695 00:24:07,909 --> 00:24:06,400 another point out is the power 696 00:24:10,310 --> 00:24:07,919 processing units are a very mature 697 00:24:12,950 --> 00:24:10,320 technology for for hall thrusters 698 00:24:15,269 --> 00:24:12,960 another area solar rays i was mentioned 699 00:24:16,390 --> 00:24:15,279 several times a lot of 700 00:24:18,310 --> 00:24:16,400 heritage 701 00:24:19,510 --> 00:24:18,320 and experience in industry that can 702 00:24:20,710 --> 00:24:19,520 support 703 00:24:22,470 --> 00:24:20,720 um what's 704 00:24:24,950 --> 00:24:22,480 what's what's what's needed to be done 705 00:24:26,390 --> 00:24:24,960 for the for the arm mission a lot of 706 00:24:27,909 --> 00:24:26,400 experience of that whether it's space 707 00:24:29,350 --> 00:24:27,919 station or all the missions you see 708 00:24:31,510 --> 00:24:29,360 listed there 709 00:24:33,830 --> 00:24:31,520 uh and then the same thing with we're 710 00:24:35,909 --> 00:24:33,840 going to xenon tanks 711 00:24:38,310 --> 00:24:35,919 we 712 00:24:39,909 --> 00:24:38,320 discussed a little bit in our response 713 00:24:41,669 --> 00:24:39,919 there is a trade whether you want to do 714 00:24:43,269 --> 00:24:41,679 a single large tank versus multiple 715 00:24:46,470 --> 00:24:43,279 small tanks there's advantages and 716 00:24:48,710 --> 00:24:46,480 disadvantages to each 717 00:24:50,630 --> 00:24:48,720 single large tank be less complex system 718 00:24:52,070 --> 00:24:50,640 but there's the smaller tanks probably 719 00:24:54,310 --> 00:24:52,080 have more applicability to other 720 00:24:55,269 --> 00:24:54,320 missions so there's more extensibility 721 00:24:57,029 --> 00:24:55,279 to 722 00:25:00,470 --> 00:24:57,039 other 723 00:25:04,710 --> 00:25:02,549 um continuing with the scp this is the 724 00:25:06,470 --> 00:25:04,720 last chart actually um 725 00:25:08,070 --> 00:25:06,480 one of the key things also going to be 726 00:25:10,070 --> 00:25:08,080 for the electric propulsion system is 727 00:25:12,789 --> 00:25:10,080 the integration and validation of the 728 00:25:14,870 --> 00:25:12,799 entire system um 729 00:25:16,230 --> 00:25:14,880 mentioned here some there is i think 730 00:25:17,750 --> 00:25:16,240 last presentation mentioned a lot 731 00:25:20,630 --> 00:25:17,760 there's a lot of experience actually 732 00:25:23,029 --> 00:25:20,640 more than you would expect in scp areas 733 00:25:29,590 --> 00:25:26,390 our the aehf mission um was a good 734 00:25:31,110 --> 00:25:29,600 demonstration of how you would use solar 735 00:25:32,630 --> 00:25:31,120 propulsion to raise it raise an orbit of 736 00:25:33,909 --> 00:25:32,640 a vehicle 737 00:25:36,149 --> 00:25:33,919 um 738 00:25:38,070 --> 00:25:36,159 and then some other areas the 739 00:25:41,269 --> 00:25:38,080 we there's been plenty of flight 740 00:25:42,950 --> 00:25:41,279 experience with uh with a 4.5 kilowatt 741 00:25:44,789 --> 00:25:42,960 hall thruster systems getting getting 742 00:25:46,310 --> 00:25:44,799 larger into the kill into the thruster 743 00:25:47,990 --> 00:25:46,320 systems 744 00:25:50,070 --> 00:25:48,000 um and then we've actually worked done 745 00:25:55,990 --> 00:25:50,080 some work developing even bigger 746 00:25:56,000 --> 00:26:00,950 i did i catch us up there that was great 747 00:26:00,960 --> 00:26:06,630 and that's it thanks 748 00:26:15,110 --> 00:26:08,310 all right so we're gonna we're gonna 749 00:26:25,430 --> 00:26:16,630 wake up 750 00:26:29,510 --> 00:26:26,789 all right we've had quite a few 751 00:26:31,830 --> 00:26:29,520 questions coming from virtually 752 00:26:33,830 --> 00:26:31,840 from our listeners i'm trying to see if 753 00:26:35,269 --> 00:26:33,840 there's one from a recent one there was 754 00:26:36,789 --> 00:26:35,279 a lot of discussion about using 755 00:26:38,630 --> 00:26:36,799 electromagnetism 756 00:26:40,070 --> 00:26:38,640 but that's probably a longer discussion 757 00:26:41,669 --> 00:26:40,080 because there's been three or four 758 00:26:42,470 --> 00:26:41,679 things come in about that 759 00:26:44,310 --> 00:26:42,480 um 760 00:26:46,310 --> 00:26:44,320 so here was a question on a recent one 761 00:26:48,950 --> 00:26:46,320 about robotic capture being vulnerable 762 00:26:50,549 --> 00:26:48,960 to surface dust and or shorting the sep 763 00:26:52,950 --> 00:26:50,559 thrusters and that came in after the 764 00:26:59,909 --> 00:26:52,960 goddard presentation you want to address 765 00:27:05,350 --> 00:27:01,830 the question was about dust and the 766 00:27:08,950 --> 00:27:06,789 well hopefully the dust doesn't get all 767 00:27:11,590 --> 00:27:08,960 around to the sep thrusters but back in 768 00:27:13,110 --> 00:27:11,600 constellation days we 769 00:27:14,950 --> 00:27:13,120 uh built a 770 00:27:17,510 --> 00:27:14,960 chamber at goddard 771 00:27:19,909 --> 00:27:17,520 to specifically either rain down dust or 772 00:27:21,830 --> 00:27:19,919 simulated regolith on mechanisms or have 773 00:27:27,190 --> 00:27:21,840 it 774 00:27:29,190 --> 00:27:27,200 only to do 775 00:27:32,549 --> 00:27:29,200 particle redistribution analysis which 776 00:27:34,549 --> 00:27:32,559 we hone for hubble space telescope 777 00:27:36,310 --> 00:27:34,559 eba operations where we were very 778 00:27:38,630 --> 00:27:36,320 contamination sensitive 779 00:27:40,870 --> 00:27:38,640 but specifically for the work that was 780 00:27:43,669 --> 00:27:40,880 going to be done with stuff driving 781 00:27:45,669 --> 00:27:43,679 around and walking around on the moon 782 00:27:47,909 --> 00:27:45,679 we had this chamber available so yes 783 00:27:51,110 --> 00:27:47,919 that is a real issue whoever sent that 784 00:27:52,630 --> 00:27:51,120 in as a very observant questioner 785 00:27:58,950 --> 00:27:52,640 and we've got facilities in place that 786 00:28:02,389 --> 00:28:00,230 good point good point a lot of 787 00:28:05,269 --> 00:28:02,399 operational experience on mars 788 00:28:06,549 --> 00:28:05,279 from our friends uh who are up there now 789 00:28:08,789 --> 00:28:06,559 driving around 790 00:28:09,990 --> 00:28:08,799 yeah good point brian 791 00:28:11,590 --> 00:28:10,000 we'll hold do you have something that's 792 00:28:13,430 --> 00:28:11,600 pressing otherwise i'd like to go to the 793 00:28:16,389 --> 00:28:13,440 next presentation but we'll get back to 794 00:28:19,269 --> 00:28:16,399 a lot of the questions 795 00:28:21,110 --> 00:28:19,279 as we go on our next presenter is 796 00:28:23,909 --> 00:28:21,120 virtual 797 00:28:26,070 --> 00:28:23,919 jonathan roble from honeybee robotics 798 00:28:27,990 --> 00:28:26,080 jonathan works there in the robotic 799 00:28:29,190 --> 00:28:28,000 spacecraft mechanisms corporation in 800 00:28:31,669 --> 00:28:29,200 longmont 801 00:28:33,430 --> 00:28:31,679 colorado honeybee develops technology 802 00:28:35,110 --> 00:28:33,440 and products for next-gen 803 00:28:38,870 --> 00:28:35,120 advanced robotic and spacecraft missions 804 00:28:40,630 --> 00:28:38,880 for nasa dod academia and industry 805 00:28:42,710 --> 00:28:40,640 jonathan will discuss several enabling 806 00:28:44,710 --> 00:28:42,720 component technologies for asteroid 807 00:28:46,470 --> 00:28:44,720 rendezvous proximity operations 808 00:28:47,909 --> 00:28:46,480 characterization and capture as well as 809 00:28:50,389 --> 00:28:47,919 technology 810 00:28:52,389 --> 00:28:50,399 can enable retrieval of a portion of the 811 00:28:55,190 --> 00:28:52,399 asteroids on the surface 812 00:28:57,590 --> 00:28:55,200 jonathan are you out there 813 00:29:00,950 --> 00:28:59,909 you here hear me all right yes 814 00:29:04,070 --> 00:29:00,960 thank you 815 00:29:05,669 --> 00:29:04,080 introduction i appreciate the 816 00:29:07,029 --> 00:29:05,679 opportunity to present the synthesis 817 00:29:08,870 --> 00:29:07,039 workshop 818 00:29:10,950 --> 00:29:08,880 uh like you said i'd like to just cover 819 00:29:12,630 --> 00:29:10,960 some of honeybees technologies that can 820 00:29:14,870 --> 00:29:12,640 contribute to asteroid redirection 821 00:29:16,470 --> 00:29:14,880 systems 822 00:29:18,149 --> 00:29:16,480 for background 823 00:29:20,470 --> 00:29:18,159 just like to say honeybee robotics is 824 00:29:23,269 --> 00:29:20,480 founded in 1983 has been developing 825 00:29:24,549 --> 00:29:23,279 spacecraft mechanisms and systems for 30 826 00:29:26,310 --> 00:29:24,559 years 827 00:29:28,230 --> 00:29:26,320 we consider our participation in nasa 828 00:29:29,990 --> 00:29:28,240 missions a key aspect of our business 829 00:29:33,269 --> 00:29:30,000 and take pride in the performance of our 830 00:29:35,510 --> 00:29:33,279 contributions including the 2003 831 00:29:36,870 --> 00:29:35,520 uh mars exploration rover rock abrasion 832 00:29:39,110 --> 00:29:36,880 tools 833 00:29:41,590 --> 00:29:39,120 the 2011 mars science laboratory 834 00:29:44,310 --> 00:29:41,600 robotics sample manipulation system and 835 00:29:47,669 --> 00:29:44,320 dust removal tool end effector 836 00:29:50,870 --> 00:29:47,679 phoenix mars lander tega dust cover and 837 00:29:53,590 --> 00:29:50,880 icy soil acquisition device 838 00:29:56,389 --> 00:29:53,600 honeybee robotics has 839 00:29:58,070 --> 00:29:56,399 done successfully 300 plus excavation on 840 00:30:03,029 --> 00:29:58,080 mars and 841 00:30:07,350 --> 00:30:04,950 as you can see honeybee robotics has 842 00:30:09,909 --> 00:30:07,360 technology suitable for topics two three 843 00:30:12,230 --> 00:30:09,919 four five and six of nasa's asteroid 844 00:30:13,909 --> 00:30:12,240 initiative but currently i'd like to 845 00:30:16,789 --> 00:30:13,919 talk to topic two 846 00:30:19,750 --> 00:30:16,799 of asteroid redirection systems 847 00:30:22,310 --> 00:30:19,760 and our sensing technologies 848 00:30:24,630 --> 00:30:22,320 for rendezvous prox ops characteristic 849 00:30:25,909 --> 00:30:24,640 characterization and capture 850 00:30:27,430 --> 00:30:25,919 we have some 851 00:30:30,070 --> 00:30:27,440 technologies to think that really help 852 00:30:31,669 --> 00:30:30,080 you see the asteroid 853 00:30:34,789 --> 00:30:31,679 one of them is our laser induced 854 00:30:36,470 --> 00:30:34,799 breakdown spectroscopy that's lids 855 00:30:38,549 --> 00:30:36,480 it's currently implemented 856 00:30:41,029 --> 00:30:38,559 in our terrestrial applications it 857 00:30:42,950 --> 00:30:41,039 allows us to vaporize and ionize surface 858 00:30:44,630 --> 00:30:42,960 material so you create a puff of plasma 859 00:30:46,630 --> 00:30:44,640 at the surface we're then able to 860 00:30:54,230 --> 00:30:46,640 capture the emission spectrum as the 861 00:30:58,230 --> 00:30:56,230 the mission spectra is representative of 862 00:31:01,350 --> 00:30:58,240 the surface material without any 863 00:31:02,630 --> 00:31:01,360 contaminants from physical 864 00:31:04,470 --> 00:31:02,640 interaction 865 00:31:06,549 --> 00:31:04,480 and so we're there by attaining a 866 00:31:11,509 --> 00:31:06,559 surface material composition uh without 867 00:31:15,830 --> 00:31:13,269 as some of the presenters mentioned 868 00:31:18,149 --> 00:31:15,840 before you're coming upon the asteroid 869 00:31:20,789 --> 00:31:18,159 possibly very little information about 870 00:31:21,909 --> 00:31:20,799 its uh composition materials and bulk 871 00:31:23,909 --> 00:31:21,919 structure 872 00:31:25,509 --> 00:31:23,919 and we think this is a 873 00:31:27,909 --> 00:31:25,519 excellent way of 874 00:31:31,350 --> 00:31:27,919 helping reduce that uncertainty before 875 00:31:33,110 --> 00:31:31,360 physical interaction with the asteroid 876 00:31:36,310 --> 00:31:33,120 this is pretty simple 877 00:31:38,710 --> 00:31:36,320 similar to the msl chemcam 878 00:31:40,710 --> 00:31:38,720 and this is a pertinent president for 879 00:31:42,389 --> 00:31:40,720 performing this type of observation 880 00:31:44,549 --> 00:31:42,399 however we prefer 881 00:31:46,149 --> 00:31:44,559 proposing to do it at a standoff 882 00:31:47,830 --> 00:31:46,159 distance so that you don't have to be 883 00:31:49,350 --> 00:31:47,840 quite 884 00:31:52,549 --> 00:31:49,360 as close to the 885 00:31:56,070 --> 00:31:52,559 material of surface material 886 00:31:58,149 --> 00:31:56,080 the other technology is a 3d lidar 887 00:31:59,430 --> 00:31:58,159 it's an improvement to machine vision 888 00:32:01,269 --> 00:31:59,440 that assists with 889 00:32:04,630 --> 00:32:01,279 detail-oriented operations while 890 00:32:06,310 --> 00:32:04,640 maintaining global awareness 891 00:32:08,710 --> 00:32:06,320 it's operating much in the way that the 892 00:32:11,190 --> 00:32:08,720 human eye does so there's a central area 893 00:32:13,590 --> 00:32:11,200 of high resolution for detail work 894 00:32:16,230 --> 00:32:13,600 combined with the low area larger area 895 00:32:17,750 --> 00:32:16,240 of low resolution for context and motion 896 00:32:19,269 --> 00:32:17,760 tracking 897 00:32:20,230 --> 00:32:19,279 this is achieved 898 00:32:23,190 --> 00:32:20,240 by 899 00:32:28,070 --> 00:32:25,830 produce a higher res 900 00:32:31,669 --> 00:32:28,080 laser pattern on an area of interest 901 00:32:33,750 --> 00:32:31,679 while doing a sparse laser pattern on 902 00:32:36,070 --> 00:32:33,760 the global area not 903 00:32:37,509 --> 00:32:36,080 thereby able to detect dynamic changes 904 00:32:39,750 --> 00:32:37,519 in the field of view 905 00:32:42,870 --> 00:32:39,760 and focus that laser scan pattern on an 906 00:32:45,430 --> 00:32:42,880 area of interest while maintaining a 907 00:32:47,269 --> 00:32:45,440 global awareness 908 00:32:49,029 --> 00:32:47,279 it allows us to map and track the 909 00:32:50,870 --> 00:32:49,039 surface of the asteroid and this is 910 00:32:53,909 --> 00:32:50,880 again significantly important for 911 00:32:55,029 --> 00:32:53,919 conducting proximity operations 912 00:32:57,350 --> 00:32:55,039 around 913 00:32:59,509 --> 00:32:57,360 uncharacterized object 914 00:33:01,110 --> 00:32:59,519 something that might might have sizable 915 00:33:03,190 --> 00:33:01,120 relief 916 00:33:05,830 --> 00:33:03,200 especially where you're looking to land 917 00:33:07,269 --> 00:33:05,840 a spacecraft and do anchoring operations 918 00:33:08,830 --> 00:33:07,279 that could be looking for a very 919 00:33:10,710 --> 00:33:08,840 specific 920 00:33:11,509 --> 00:33:10,720 placement 921 00:33:13,509 --> 00:33:11,519 so 922 00:33:16,070 --> 00:33:13,519 both of these technologies allow 923 00:33:18,870 --> 00:33:16,080 spacecraft to characterize its otherwise 924 00:33:21,029 --> 00:33:18,880 unknown target and operate inside of a 925 00:33:23,029 --> 00:33:21,039 feedback loop 926 00:33:25,190 --> 00:33:23,039 and control algorithms 927 00:33:27,590 --> 00:33:25,200 for proximity apps 928 00:33:29,830 --> 00:33:27,600 now in addition to these 929 00:33:30,950 --> 00:33:29,840 technologies if to further characterize 930 00:33:35,190 --> 00:33:30,960 the 931 00:33:37,430 --> 00:33:35,200 asteroid before interaction we have 932 00:33:41,029 --> 00:33:37,440 some past work with impactors which 933 00:33:43,190 --> 00:33:41,039 would in addition to giving you 934 00:33:45,909 --> 00:33:43,200 composition it could give you property 935 00:33:48,389 --> 00:33:45,919 information uh by characterizing the 936 00:33:50,710 --> 00:33:48,399 ejective plume from impact 937 00:33:52,470 --> 00:33:50,720 this is our across 938 00:33:53,909 --> 00:33:52,480 technology 939 00:33:56,789 --> 00:33:53,919 in addition 940 00:33:57,830 --> 00:33:56,799 we can touch it um with a touch and go 941 00:34:00,549 --> 00:33:57,840 sampler 942 00:34:03,190 --> 00:34:00,559 that allows you to use a tethered sample 943 00:34:04,870 --> 00:34:03,200 collection to assay the surface before 944 00:34:08,790 --> 00:34:04,880 committing to it 945 00:34:13,109 --> 00:34:10,310 basically a 946 00:34:15,829 --> 00:34:13,119 propelled drill 947 00:34:18,149 --> 00:34:15,839 furthermore we can harpoon sample it and 948 00:34:19,270 --> 00:34:18,159 these will be talked about in other 949 00:34:20,790 --> 00:34:19,280 discussions 950 00:34:22,950 --> 00:34:20,800 which 951 00:34:24,790 --> 00:34:22,960 can again give you that a priori 952 00:34:27,510 --> 00:34:24,800 knowledge before uh 953 00:34:31,990 --> 00:34:29,750 we can drill with honeybees extensive 954 00:34:33,829 --> 00:34:32,000 history and robotic joint and sample 955 00:34:35,270 --> 00:34:33,839 collection 956 00:34:38,470 --> 00:34:35,280 can 957 00:34:41,510 --> 00:34:38,480 get below just the surface properties 958 00:34:43,829 --> 00:34:41,520 of the asteroid 959 00:34:45,669 --> 00:34:43,839 to understand how it's going to act 960 00:34:47,669 --> 00:34:45,679 when you attempt to apply 961 00:34:49,829 --> 00:34:47,679 redirect forces to it and 962 00:34:51,430 --> 00:34:49,839 touch down on it 963 00:34:53,190 --> 00:34:51,440 once you're down there we can 964 00:34:55,909 --> 00:34:53,200 inhale it as we say 965 00:34:59,190 --> 00:34:55,919 with a pneumatic sampler and excavation 966 00:35:02,950 --> 00:34:59,200 system that allows us to collect 967 00:35:04,710 --> 00:35:02,960 either cutting tailings or loose surface 968 00:35:05,670 --> 00:35:04,720 materials 969 00:35:07,910 --> 00:35:05,680 and 970 00:35:11,750 --> 00:35:07,920 we can snare small objects 971 00:35:15,750 --> 00:35:13,910 and then we can also anchor to it with a 972 00:35:17,510 --> 00:35:15,760 self-opposed multi-mode anchoring 973 00:35:18,630 --> 00:35:17,520 technologies that we have 974 00:35:20,710 --> 00:35:18,640 developed 975 00:35:22,310 --> 00:35:20,720 through past work 976 00:35:25,430 --> 00:35:22,320 that allow you to 977 00:35:26,950 --> 00:35:25,440 touch down and produce a firm base 978 00:35:29,349 --> 00:35:26,960 station with it 979 00:35:31,190 --> 00:35:29,359 lastly we have done work with 980 00:35:32,550 --> 00:35:31,200 full asteroid capture if it's small 981 00:35:34,390 --> 00:35:32,560 enough 982 00:35:36,710 --> 00:35:34,400 and these are just some of the 983 00:35:37,430 --> 00:35:36,720 capabilities that we have 984 00:35:39,030 --> 00:35:37,440 and 985 00:35:42,310 --> 00:35:39,040 others will be talked about more in the 986 00:35:43,589 --> 00:35:42,320 different topics we think that 987 00:35:45,670 --> 00:35:43,599 the 988 00:35:48,150 --> 00:35:45,680 past work that honeybees done has 989 00:35:49,670 --> 00:35:48,160 prepared us to support a asteroid 990 00:35:52,310 --> 00:35:49,680 redirect mission 991 00:35:53,270 --> 00:35:52,320 and uh if you guys have any questions uh 992 00:35:55,030 --> 00:35:53,280 i guess 993 00:35:57,030 --> 00:35:55,040 i'll stick it out afterwards or open 994 00:35:59,190 --> 00:35:57,040 them now if there's time 995 00:36:01,589 --> 00:35:59,200 okay great jonathan um i think we have 996 00:36:02,710 --> 00:36:01,599 time for one or two questions preferably 997 00:36:04,150 --> 00:36:02,720 first of all 998 00:36:12,069 --> 00:36:04,160 focused on something directly for 999 00:36:15,349 --> 00:36:13,109 okay 1000 00:36:17,670 --> 00:36:15,359 jonathan and if if not i encourage you 1001 00:36:19,990 --> 00:36:17,680 guys to contact us at info honeybee 1002 00:36:21,910 --> 00:36:20,000

would appreciate 1006 00:36:35,109 --> 00:36:30,160 if you can stick around for our 1007 00:36:39,589 --> 00:36:37,670 okay our next speaker stephen warwick 1008 00:36:41,030 --> 00:36:39,599 from northrop grumman he's a system 1009 00:36:42,390 --> 00:36:41,040 engineer in the system engineering 1010 00:36:43,829 --> 00:36:42,400 directorate 1011 00:36:45,829 --> 00:36:43,839 he earned his bachelor's degree in 1012 00:36:48,069 --> 00:36:45,839 physics from leicester university in the 1013 00:36:50,550 --> 00:36:48,079 united kingdom and his master's at 1014 00:36:52,310 --> 00:36:50,560 cranfield university steve will talk 1015 00:36:54,150 --> 00:36:52,320 about an integrated sensor system to 1016 00:36:56,790 --> 00:36:54,160 support asteroid characterization 1017 00:36:58,630 --> 00:36:56,800 proximity operations and capture 1018 00:37:00,230 --> 00:36:58,640 thank you very much and it's a pleasure 1019 00:37:02,069 --> 00:37:00,240 to be here this afternoon i'm here on 1020 00:37:03,829 --> 00:37:02,079 behalf of northrop grumman and i'm going 1021 00:37:05,829 --> 00:37:03,839 to be talking about the integrated 1022 00:37:07,910 --> 00:37:05,839 sensor system what we hope to do with 1023 00:37:09,910 --> 00:37:07,920 this was look at a layered approach that 1024 00:37:12,550 --> 00:37:09,920 will give us information as we approach 1025 00:37:13,589 --> 00:37:12,560 the asteroid and one of these buttons 1026 00:37:15,109 --> 00:37:13,599 works 1027 00:37:19,430 --> 00:37:15,119 top one 1028 00:37:21,510 --> 00:37:19,440 there we go 1029 00:37:23,109 --> 00:37:21,520 all right this is part of three talks 1030 00:37:25,829 --> 00:37:23,119 that northrop grumman will be giving 1031 00:37:27,910 --> 00:37:25,839 over the next two days provided people 1032 00:37:30,150 --> 00:37:27,920 in washington have any sense 1033 00:37:31,670 --> 00:37:30,160 um today i'm talking about integrated 1034 00:37:34,390 --> 00:37:31,680 sensing systems tomorrow we're looking 1035 00:37:36,550 --> 00:37:34,400 at the asteroid deflection system that's 1036 00:37:38,790 --> 00:37:36,560 given by jim munger that's pushing the 1037 00:37:40,069 --> 00:37:38,800 larger objects and then also tomorrow 1038 00:37:43,030 --> 00:37:40,079 afternoon we're looking at asteroid 1039 00:37:44,950 --> 00:37:43,040 capture with uh howard ella 1040 00:37:47,190 --> 00:37:44,960 so what we were hoping to do when we 1041 00:37:49,270 --> 00:37:47,200 took a look at this is produce a layered 1042 00:37:52,390 --> 00:37:49,280 sensing approach that is going to buy 1043 00:37:54,390 --> 00:37:52,400 down risk as we fly towards the asteroid 1044 00:37:56,310 --> 00:37:54,400 this is going to be something unusual in 1045 00:37:58,390 --> 00:37:56,320 nasa land because we are not going to 1046 00:38:00,390 --> 00:37:58,400 know what we're really going to do until 1047 00:38:01,589 --> 00:38:00,400 we get close to the object 1048 00:38:03,670 --> 00:38:01,599 we're going to be launching with a 1049 00:38:04,870 --> 00:38:03,680 significant amount of risk in the 1050 00:38:07,109 --> 00:38:04,880 program 1051 00:38:08,870 --> 00:38:07,119 and when we were looking at what sensors 1052 00:38:11,430 --> 00:38:08,880 were useful to us and what would help us 1053 00:38:12,470 --> 00:38:11,440 buy down the risk we had a straw man 1054 00:38:15,270 --> 00:38:12,480 mission 1055 00:38:17,109 --> 00:38:15,280 and we gave a orbit condition code of 1056 00:38:19,270 --> 00:38:17,119 one if you know these things that's 1057 00:38:22,230 --> 00:38:19,280 actually knowing the orbit very well 1058 00:38:24,150 --> 00:38:22,240 uh h mag of 28.5 that's the brightness 1059 00:38:25,990 --> 00:38:24,160 of the object from the ground but what 1060 00:38:28,790 --> 00:38:26,000 we don't know about the object at all is 1061 00:38:30,550 --> 00:38:28,800 the real diameter the mass the spin rate 1062 00:38:32,470 --> 00:38:30,560 whether there's a binary with the object 1063 00:38:35,589 --> 00:38:32,480 or any kind of debris field and what 1064 00:38:37,589 --> 00:38:35,599 this series of sensors is going to do is 1065 00:38:39,430 --> 00:38:37,599 find that information out 1066 00:38:40,870 --> 00:38:39,440 and reduce the risk to the capture 1067 00:38:43,349 --> 00:38:40,880 vehicle 1068 00:38:45,829 --> 00:38:43,359 all right so starting 10 000 kilometers 1069 00:38:47,589 --> 00:38:45,839 or more away from the the asteroid and 1070 00:38:48,950 --> 00:38:47,599 we suggested uh visible and 1071 00:38:51,910 --> 00:38:48,960 near-infrared 1072 00:38:53,589 --> 00:38:51,920 banned telescopes maybe six inch optics 1073 00:38:55,510 --> 00:38:53,599 and they have quite a large field of 1074 00:38:58,069 --> 00:38:55,520 view and would be scanning those to look 1075 00:38:59,589 --> 00:38:58,079 for the asteroid one of the things about 1076 00:39:01,190 --> 00:38:59,599 approaching one of these asteroids is 1077 00:39:04,069 --> 00:39:01,200 even when the orbit condition is 1078 00:39:05,990 --> 00:39:04,079 relatively good we're still not 100 sure 1079 00:39:07,430 --> 00:39:06,000 where they are the the mission is going 1080 00:39:08,870 --> 00:39:07,440 to have to find the asteroid as it 1081 00:39:11,190 --> 00:39:08,880 approaches 1082 00:39:13,510 --> 00:39:11,200 and the goal here is to improve the 1083 00:39:15,430 --> 00:39:13,520 orbit accuracy know our distance to the 1084 00:39:17,910 --> 00:39:15,440 object as well i mean there's some other 1085 00:39:20,710 --> 00:39:17,920 information we may be able to find out 1086 00:39:22,470 --> 00:39:20,720 we may be able to get a spin state from 1087 00:39:24,630 --> 00:39:22,480 a light curve as well using this 1088 00:39:26,790 --> 00:39:24,640 instrument but primarily this is about 1089 00:39:28,550 --> 00:39:26,800 finding the asteroid and there on the 1090 00:39:30,790 --> 00:39:28,560 slide on the right and you can see the 1091 00:39:32,870 --> 00:39:30,800 advantage of infrared over visible it 1092 00:39:35,349 --> 00:39:32,880 gives you a better idea of the size of 1093 00:39:37,910 --> 00:39:35,359 the object you're going to be looking at 1094 00:39:39,430 --> 00:39:37,920 okay we get closer to the object and 1095 00:39:41,349 --> 00:39:39,440 from 100 kilometers or so we're 1096 00:39:42,630 --> 00:39:41,359 suggesting a radar ground penetrating 1097 00:39:43,829 --> 00:39:42,640 radar 1098 00:39:45,430 --> 00:39:43,839 obviously that gives you 1099 00:39:48,470 --> 00:39:45,440 characterization of the shape of the 1100 00:39:50,550 --> 00:39:48,480 object uh it improves your ranging to 1101 00:39:52,870 --> 00:39:50,560 the object now you know even to higher 1102 00:39:54,230 --> 00:39:52,880 accuracy how where the object is 1103 00:39:55,910 --> 00:39:54,240 and you're going to get some information 1104 00:39:57,670 --> 00:39:55,920 about the spin state or the tumbling 1105 00:39:59,430 --> 00:39:57,680 nature of the asteroid and of course 1106 00:40:00,710 --> 00:39:59,440 because it's ground penetrating radar 1107 00:40:02,630 --> 00:40:00,720 that's going to give you your first 1108 00:40:04,790 --> 00:40:02,640 indication of whether you're dealing 1109 00:40:06,550 --> 00:40:04,800 with a monolithic rock or you're dealing 1110 00:40:08,550 --> 00:40:06,560 with one of these rubble piles and 1111 00:40:11,190 --> 00:40:08,560 that's obviously going to be critical 1112 00:40:15,109 --> 00:40:11,200 for the for the safety of the capture 1113 00:40:18,069 --> 00:40:15,119 spacecraft as it approaches the object 1114 00:40:20,069 --> 00:40:18,079 getting closer still 50 kilometers or so 1115 00:40:23,349 --> 00:40:20,079 uh lidar radar 1116 00:40:26,550 --> 00:40:23,359 and be able to generate a 3d model of 1117 00:40:27,910 --> 00:40:26,560 the asteroid as it spans and obviously 1118 00:40:29,190 --> 00:40:27,920 we don't expect these objects to be 1119 00:40:30,790 --> 00:40:29,200 circular they're going to be quite 1120 00:40:33,430 --> 00:40:30,800 irregular this will give us our 1121 00:40:34,790 --> 00:40:33,440 indication of of what nature of 1122 00:40:37,670 --> 00:40:34,800 irregular object we're going to be 1123 00:40:42,230 --> 00:40:40,309 and getting closer still and we quite 1124 00:40:45,430 --> 00:40:42,240 like this one this is a 1125 00:40:48,069 --> 00:40:45,440 cubesat we uh and back in 2010 northrop 1126 00:40:50,150 --> 00:40:48,079 launched a cubesat called mayflower the 1127 00:40:51,990 --> 00:40:50,160 next generation of that plymouth is a 1128 00:40:53,190 --> 00:40:52,000 three axis stabilized three by one 1129 00:40:56,069 --> 00:40:53,200 cubesat 1130 00:40:57,190 --> 00:40:56,079 and it also has some delta v on board 20 1131 00:40:58,790 --> 00:40:57,200 25 1132 00:41:01,670 --> 00:40:58,800 and meters a second 1133 00:41:04,069 --> 00:41:01,680 and it has capacity for a reasonable 1134 00:41:06,069 --> 00:41:04,079 amount of solar array on there as well 1135 00:41:07,190 --> 00:41:06,079 and it has its own instrument suite 1136 00:41:09,750 --> 00:41:07,200 called dark 1137 00:41:10,630 --> 00:41:09,760 that has a camera radar and lidar of its 1138 00:41:12,309 --> 00:41:10,640 own 1139 00:41:14,870 --> 00:41:12,319 and what you get from that is the 1140 00:41:16,630 --> 00:41:14,880 ability for the capture spacecraft to be 1141 00:41:17,750 --> 00:41:16,640 set a reasonable distance away from the 1142 00:41:19,990 --> 00:41:17,760 asteroid 1143 00:41:21,670 --> 00:41:20,000 safe from any debris or any other 1144 00:41:23,510 --> 00:41:21,680 problem that the asteroid 1145 00:41:25,589 --> 00:41:23,520 may threaten them to capture vehicle 1146 00:41:28,069 --> 00:41:25,599 with and get very very close with one of 1147 00:41:30,150 --> 00:41:28,079 these objects and with one of these 1148 00:41:32,710 --> 00:41:30,160 cubesats um 1149 00:41:35,349 --> 00:41:32,720 down to 50 meters or so range 1150 00:41:37,589 --> 00:41:35,359 a real advantage of this is we realize 1151 00:41:39,270 --> 00:41:37,599 that as you approach the asteroid and 1152 00:41:41,510 --> 00:41:39,280 station keep with the asteroid using the 1153 00:41:43,910 --> 00:41:41,520 cubesat and you watch it for a couple of 1154 00:41:45,990 --> 00:41:43,920 days then relative to the the primary 1155 00:41:47,190 --> 00:41:46,000 spacecraft you're going to see very slow 1156 00:41:49,589 --> 00:41:47,200 acceleration and that's the 1157 00:41:51,190 --> 00:41:49,599 gravitational field of the asteroid and 1158 00:41:52,710 --> 00:41:51,200 i'll give you your first indications of 1159 00:41:56,309 --> 00:41:52,720 the true mass of the asteroid that 1160 00:42:00,950 --> 00:41:58,230 and getting closer still and this is 1161 00:42:02,790 --> 00:42:00,960 another q-type concept if the if the 1162 00:42:04,790 --> 00:42:02,800 ball there looks familiar that's because 1163 00:42:08,870 --> 00:42:04,800 we developed it with honeybee 1164 00:42:11,990 --> 00:42:08,880 uh for a discovery program in 2010 and 1165 00:42:14,150 --> 00:42:12,000 also an at ames research center we call 1166 00:42:16,470 --> 00:42:14,160 these impactors really we've also used 1167 00:42:18,309 --> 00:42:16,480 the name thumpers they're intended to 1168 00:42:20,950 --> 00:42:18,319 impact very slowly 1169 00:42:23,990 --> 00:42:20,960 meters a second the accelerometers 1170 00:42:26,630 --> 00:42:24,000 inside the ball give you uh 1171 00:42:28,630 --> 00:42:26,640 more information on the composition of 1172 00:42:30,630 --> 00:42:28,640 the asteroid whether you're hitting dust 1173 00:42:32,710 --> 00:42:30,640 grains or solid rock 1174 00:42:34,470 --> 00:42:32,720 and then there's another version the the 1175 00:42:36,710 --> 00:42:34,480 one you cube sound that's got cameras on 1176 00:42:38,470 --> 00:42:36,720 board and an electrostatic probe to give 1177 00:42:39,910 --> 00:42:38,480 you any idea of any kind of electrical 1178 00:42:42,069 --> 00:42:39,920 field that the 1179 00:42:44,790 --> 00:42:42,079 asteroid may have in any kind of dust 1180 00:42:46,710 --> 00:42:44,800 environment around it both the cubesat 1181 00:42:48,470 --> 00:42:46,720 concepts we've shown here they are 1182 00:42:50,710 --> 00:42:48,480 moderately low trl as it stands at the 1183 00:42:53,910 --> 00:42:50,720 moment but we've shown that you can go 1184 00:42:57,349 --> 00:42:53,920 from concept to launch with a cubesat in 1185 00:42:58,630 --> 00:42:57,359 six months or so so we would expect uh 1186 00:43:01,030 --> 00:42:58,640 if we were going to do something like 1187 00:43:02,950 --> 00:43:01,040 this to actually be flying 1188 00:43:04,790 --> 00:43:02,960 uh the cubesats ahead of time in low 1189 00:43:06,230 --> 00:43:04,800 earth orbit 1190 00:43:08,550 --> 00:43:06,240 and 1191 00:43:10,710 --> 00:43:08,560 the uh 1192 00:43:13,589 --> 00:43:10,720 sorry let me uh 1193 00:43:15,750 --> 00:43:13,599 but in both cases they uh are they're 1194 00:43:17,270 --> 00:43:15,760 not exquisite technology they are they 1195 00:43:20,150 --> 00:43:17,280 are commercial off-the-shelf type 1196 00:43:22,309 --> 00:43:20,160 technology and we achieve redundancy by 1197 00:43:25,190 --> 00:43:22,319 having multiple copies of of all the 1198 00:43:26,550 --> 00:43:25,200 cubesats we've shown here 1199 00:43:29,589 --> 00:43:26,560 so in summary hopefully what we're 1200 00:43:31,190 --> 00:43:29,599 showing here is a series a layered 1201 00:43:33,750 --> 00:43:31,200 approach that's going to buy down the 1202 00:43:35,829 --> 00:43:33,760 risk as we actually fly the mission and 1203 00:43:37,829 --> 00:43:35,839 how we get close to the object how we 1204 00:43:39,349 --> 00:43:37,839 find out what the object really is and 1205 00:43:42,390 --> 00:43:39,359 how we can model 1206 00:43:44,710 --> 00:43:42,400 the composition the shape the tumble and 1207 00:43:47,109 --> 00:43:44,720 spin of the object on the ground in such 1208 00:43:49,270 --> 00:43:47,119 a way that safe capture of the asteroid 1209 00:43:51,349 --> 00:43:49,280 can be achieved 1210 00:44:10,550 --> 00:43:51,359 all right 1211 00:44:13,510 --> 00:44:11,910 can you give us a 1212 00:44:15,030 --> 00:44:13,520 an idea of what a ground penetrating 1213 00:44:17,910 --> 00:44:15,040 radar might cost 1214 00:44:23,670 --> 00:44:17,920 uh i i'm afraid i can't no i don't have 1215 00:44:27,270 --> 00:44:25,510 anybody else 1216 00:44:29,030 --> 00:44:27,280 anything uh coming in 1217 00:44:32,950 --> 00:44:29,040 from 1218 00:44:32,960 --> 00:44:36,630 thank you 1219 00:44:40,710 --> 00:44:39,589 um our next presenter 1220 00:44:45,190 --> 00:44:40,720 is 1221 00:44:46,950 --> 00:44:45,200 rich 1222 00:44:48,870 --> 00:44:46,960 works in business development and civil 1223 00:44:51,349 --> 00:44:48,880 space and technologies at ball aerospace 1224 00:44:53,030 --> 00:44:51,359 he's primarily responsible for the 1225 00:44:55,430 --> 00:44:53,040 pursuit and formulation of instruments 1226 00:44:56,950 --> 00:44:55,440 in spacecraft for science missions he 1227 00:44:59,670 --> 00:44:56,960 received a doctorate in planetary 1228 00:45:01,589 --> 00:44:59,680 sciences from caltech in 1994 1229 00:45:03,430 --> 00:45:01,599 his talk will 1230 00:45:04,470 --> 00:45:03,440 evaluate sensing requirements for arm 1231 00:45:11,349 --> 00:45:04,480 and 1232 00:45:12,870 --> 00:45:11,359 along with several other folks in the 1233 00:45:13,910 --> 00:45:12,880 room i think so 1234 00:45:15,910 --> 00:45:13,920 um 1235 00:45:18,630 --> 00:45:15,920 it's getting better now though at least 1236 00:45:20,230 --> 00:45:18,640 at least in a lot of areas um 1237 00:45:22,710 --> 00:45:20,240 so this this is a 1238 00:45:23,829 --> 00:45:22,720 sound kind of familiar to uh 1239 00:45:25,190 --> 00:45:23,839 you know it's kind of along the same 1240 00:45:26,950 --> 00:45:25,200 theme of several other talks so i'm 1241 00:45:29,270 --> 00:45:26,960 gonna i'm gonna focus uh more on a 1242 00:45:31,750 --> 00:45:29,280 couple of things toward the end but we 1243 00:45:33,589 --> 00:45:31,760 looked at the uh the not nominal arm 1244 00:45:35,270 --> 00:45:33,599 scenario to say what are the kind of 1245 00:45:36,870 --> 00:45:35,280 what's the minimum base set of sensors 1246 00:45:38,230 --> 00:45:36,880 that you might need for this 1247 00:45:39,990 --> 00:45:38,240 um 1248 00:45:41,670 --> 00:45:40,000 just to get to the punch line i see a 1249 00:45:43,270 --> 00:45:41,680 minimum set being a narrow and wide 1250 00:45:45,670 --> 00:45:43,280 field of view visible imagers and an 1251 00:45:47,670 --> 00:45:45,680 imaging lidar sounds like a similar 1252 00:45:49,750 --> 00:45:47,680 conclusion although there's some nuances 1253 00:45:51,030 --> 00:45:49,760 there uh what senses are available want 1254 00:45:53,990 --> 00:45:51,040 to talk to that a little bit are there 1255 00:45:55,670 --> 00:45:54,000 some gaps in uh in the sensing 1256 00:45:57,510 --> 00:45:55,680 technology we heard a lot about there 1257 00:45:58,790 --> 00:45:57,520 are a lot of high trl 1258 00:46:00,870 --> 00:45:58,800 things available right now i think 1259 00:46:03,430 --> 00:46:00,880 that's true in the hardware side i'm i'm 1260 00:46:05,349 --> 00:46:03,440 more concerned about uh in this the 1261 00:46:06,950 --> 00:46:05,359 fully autonomous software for prox ops 1262 00:46:08,390 --> 00:46:06,960 there's a lot of work going on there 1263 00:46:10,790 --> 00:46:08,400 fantastic work in a lot of different 1264 00:46:12,790 --> 00:46:10,800 locations but you got to piece all that 1265 00:46:15,510 --> 00:46:12,800 together and make it make it uh 1266 00:46:17,589 --> 00:46:15,520 robust uh and fully autonomous for for 1267 00:46:19,430 --> 00:46:17,599 flight ops here that that that to me is 1268 00:46:20,950 --> 00:46:19,440 the the a big kicker that we need to 1269 00:46:22,630 --> 00:46:20,960 concentrate on 1270 00:46:25,510 --> 00:46:22,640 um this is also as we've heard 1271 00:46:27,670 --> 00:46:25,520 applicable to a number of um other other 1272 00:46:30,790 --> 00:46:27,680 mission concepts recon missions to small 1273 00:46:33,990 --> 00:46:30,800 bodies arnd orbital remediation 1274 00:46:36,230 --> 00:46:34,000 satellite servicing so 1275 00:46:39,589 --> 00:46:36,240 leave it at that so this is my rendition 1276 00:46:41,750 --> 00:46:39,599 of what the mission looks like 1277 00:46:43,829 --> 00:46:41,760 several different uh 1278 00:46:45,750 --> 00:46:43,839 distances here and what kind of sensors 1279 00:46:49,190 --> 00:46:45,760 you you can see here 1280 00:46:51,430 --> 00:46:49,200 being being needed to be applied for for 1281 00:46:54,390 --> 00:46:51,440 navigation and prox ops 1282 00:46:56,309 --> 00:46:54,400 the narrow field of view imagery far out 1283 00:46:58,150 --> 00:46:56,319 as you get getting closer and closer you 1284 00:47:00,630 --> 00:46:58,160 start bringing in lidar in order to get 1285 00:47:02,710 --> 00:47:00,640 to get bearing information then pose 1286 00:47:04,150 --> 00:47:02,720 information further in uh need to get 1287 00:47:06,150 --> 00:47:04,160 surface features and have the surface 1288 00:47:08,390 --> 00:47:06,160 features blended in to the to the pose 1289 00:47:10,470 --> 00:47:08,400 model as well 1290 00:47:12,630 --> 00:47:10,480 but what's missing out of all these that 1291 00:47:14,950 --> 00:47:12,640 i see is that you you don't really have 1292 00:47:16,710 --> 00:47:14,960 any kind of information solid 1293 00:47:19,109 --> 00:47:16,720 information anyway about mechanical 1294 00:47:21,829 --> 00:47:19,119 properties of the target now i've 1295 00:47:23,510 --> 00:47:21,839 heard a lot of good good talk and i want 1296 00:47:25,990 --> 00:47:23,520 to hear more discussion about 1297 00:47:28,549 --> 00:47:26,000 this airbag technique being 1298 00:47:30,390 --> 00:47:28,559 robust to to any any range of mechanical 1299 00:47:32,390 --> 00:47:30,400 properties that would scare me thinking 1300 00:47:35,270 --> 00:47:32,400 about this is going to be a you know 1301 00:47:37,430 --> 00:47:35,280 tens of minute kind of operation to to 1302 00:47:38,950 --> 00:47:37,440 go in and move in maneuver around 1303 00:47:40,950 --> 00:47:38,960 something like that 1304 00:47:42,950 --> 00:47:40,960 and encapsulate it and then have some 1305 00:47:44,630 --> 00:47:42,960 other diaphragm come around it and then 1306 00:47:48,069 --> 00:47:44,640 release the airbags in the meantime 1307 00:47:49,589 --> 00:47:48,079 nothing has touched the surface at all 1308 00:47:50,470 --> 00:47:49,599 i think there might be a range of 1309 00:47:53,030 --> 00:47:50,480 different 1310 00:47:54,309 --> 00:47:53,040 conops we might think about here 1311 00:47:55,430 --> 00:47:54,319 depending on whether we've got good 1312 00:47:57,589 --> 00:47:55,440 information about the mechanical 1313 00:47:58,870 --> 00:47:57,599 properties or not of this object so i 1314 00:48:00,790 --> 00:47:58,880 would think you would want to be 1315 00:48:03,829 --> 00:48:00,800 informed of that ahead of time not just 1316 00:48:07,270 --> 00:48:04,549 so 1317 00:48:09,430 --> 00:48:07,280 getting back though to flat flash lidar 1318 00:48:10,470 --> 00:48:09,440 um there are a number of different uh 1319 00:48:11,750 --> 00:48:10,480 candidate 1320 00:48:13,349 --> 00:48:11,760 technologies out there that are high 1321 00:48:16,150 --> 00:48:13,359 tier all right now we we have one at 1322 00:48:17,750 --> 00:48:16,160 ball as well uh this uh vns the vision 1323 00:48:18,829 --> 00:48:17,760 navigation center 1324 00:48:22,790 --> 00:48:18,839 flew on 1325 00:48:24,309 --> 00:48:22,800 sts-134 here you can see a visible image 1326 00:48:26,470 --> 00:48:24,319 along with the 1327 00:48:28,870 --> 00:48:26,480 there's a visible camera along with that 1328 00:48:30,390 --> 00:48:28,880 the vns flash lighter intensity image is 1329 00:48:32,549 --> 00:48:30,400 here and the range images here as it's 1330 00:48:35,190 --> 00:48:32,559 approaching the this docking ring on on 1331 00:48:37,030 --> 00:48:35,200 the iss and flash lighter as you may 1332 00:48:39,349 --> 00:48:37,040 know you know illuminates an entire 1333 00:48:41,750 --> 00:48:39,359 field of view all at once all the pixels 1334 00:48:43,910 --> 00:48:41,760 come back with with a range in real time 1335 00:48:45,270 --> 00:48:43,920 this uh this particular device operates 1336 00:48:47,190 --> 00:48:45,280 at 30 hertz 1337 00:48:48,549 --> 00:48:47,200 uh you can enhance this with adaptive 1338 00:48:50,230 --> 00:48:48,559 beam steering 1339 00:48:52,470 --> 00:48:50,240 we've done some of that a ball of this 1340 00:48:55,349 --> 00:48:52,480 this unit didn't have that 1341 00:48:57,829 --> 00:48:55,359 but there are ways to enhance the uh 1342 00:48:58,549 --> 00:48:57,839 the operability of this for 1343 00:49:00,630 --> 00:48:58,559 for 1344 00:49:02,950 --> 00:49:00,640 high dynamic range targets 1345 00:49:04,630 --> 00:49:02,960 and we've also looked at ways to enhance 1346 00:49:09,030 --> 00:49:04,640 the radiometric performance you can make 1347 00:49:11,510 --> 00:49:09,910 by 1348 00:49:13,109 --> 00:49:11,520 some pretty simple tweaks to this this 1349 00:49:14,710 --> 00:49:13,119 was made to look at rector reflectors on 1350 00:49:15,910 --> 00:49:14,720 the iss but 1351 00:49:17,510 --> 00:49:15,920 you can see you're seeing a lot of the 1352 00:49:19,109 --> 00:49:17,520 skin of the 1353 00:49:20,230 --> 00:49:19,119 iss where the erect reflectors aren't 1354 00:49:21,910 --> 00:49:20,240 there's a retro right there that very 1355 00:49:24,069 --> 00:49:21,920 bright object 1356 00:49:25,430 --> 00:49:24,079 but you can you can tweak this by 1357 00:49:26,870 --> 00:49:25,440 removing the 1358 00:49:28,950 --> 00:49:26,880 optical parametric oscillator for 1359 00:49:30,309 --> 00:49:28,960 instance get about five times the 1360 00:49:31,990 --> 00:49:30,319 performance on that there are a number 1361 00:49:33,670 --> 00:49:32,000 of different things you can do to if 1362 00:49:36,630 --> 00:49:33,680 you're willing to compromise eye safety 1363 00:49:39,750 --> 00:49:36,640 you can make this uh you know be able to 1364 00:49:42,150 --> 00:49:39,760 see a lot on the dark target 1365 00:49:44,630 --> 00:49:42,160 um as i mentioned the technology gap i 1366 00:49:46,790 --> 00:49:44,640 see is this the really the need for 1367 00:49:49,510 --> 00:49:46,800 robust real-time fully autonomous 1368 00:49:51,109 --> 00:49:49,520 proximity ops uh you know this this has 1369 00:49:52,390 --> 00:49:51,119 been uh looked at from a number of 1370 00:49:54,950 --> 00:49:52,400 different angles that you know we've 1371 00:49:56,390 --> 00:49:54,960 heard about the sosc uh as i understand 1372 00:49:58,230 --> 00:49:56,400 there's gonna be a morpheus landing test 1373 00:50:00,470 --> 00:49:58,240 that looks at terrain relative nav and 1374 00:50:02,470 --> 00:50:00,480 hazard avoidance in the loop as part of 1375 00:50:04,630 --> 00:50:02,480 that those are all great things they 1376 00:50:07,510 --> 00:50:04,640 move us the right direction 1377 00:50:09,670 --> 00:50:07,520 one example of data here is to fuse 1378 00:50:11,910 --> 00:50:09,680 visible data from the camera 1379 00:50:12,630 --> 00:50:11,920 with the lighter image and be able to to 1380 00:50:15,270 --> 00:50:12,640 get 1381 00:50:17,430 --> 00:50:15,280 uh information real time and you know 1382 00:50:19,990 --> 00:50:17,440 that's that's uh doesn't matter what the 1383 00:50:22,630 --> 00:50:20,000 elimination conditions are 1384 00:50:24,150 --> 00:50:22,640 so that that needs to be 1385 00:50:25,430 --> 00:50:24,160 you need to know exactly what features 1386 00:50:27,510 --> 00:50:25,440 you're seeing on the on the target as 1387 00:50:29,670 --> 00:50:27,520 well so you get the full pose estimation 1388 00:50:31,510 --> 00:50:29,680 in in real time so you you know where 1389 00:50:33,030 --> 00:50:31,520 you are relative to all those features 1390 00:50:36,150 --> 00:50:33,040 on the asteroid as you're doing these 1391 00:50:37,430 --> 00:50:36,160 these proximity operations 1392 00:50:38,950 --> 00:50:37,440 as is 1393 00:50:40,950 --> 00:50:38,960 as i mentioned i don't i don't see this 1394 00:50:41,829 --> 00:50:40,960 as it's being done in pieces right now 1395 00:50:43,349 --> 00:50:41,839 um 1396 00:50:46,150 --> 00:50:43,359 there needs to be a 1397 00:50:47,990 --> 00:50:46,160 uh you know a full end-to-end uh 1398 00:50:49,910 --> 00:50:48,000 simulation that brings all this together 1399 00:50:51,510 --> 00:50:49,920 i think to really make this robust that 1400 00:50:55,270 --> 00:50:51,520 i think that's gonna be a major 1401 00:50:56,069 --> 00:50:55,280 uh hurdle in this in this mission 1402 00:50:57,829 --> 00:50:56,079 um 1403 00:50:59,589 --> 00:50:57,839 as you saw in john brophy's talk as well 1404 00:51:02,150 --> 00:50:59,599 there was a this picture was up in the 1405 00:51:05,030 --> 00:51:02,160 upper right hand corner of a possible 1406 00:51:06,390 --> 00:51:05,040 augmentation to uh to to 1407 00:51:08,549 --> 00:51:06,400 some of the 1408 00:51:10,790 --> 00:51:08,559 sensors that might be on this this was 1409 00:51:12,870 --> 00:51:10,800 uh you know not really a cubesat a 1410 00:51:14,309 --> 00:51:12,880 sphere set uh i guess 1411 00:51:16,390 --> 00:51:14,319 you saw it's on the last one there was a 1412 00:51:18,309 --> 00:51:16,400 sphere as well this is actually pretty 1413 00:51:20,630 --> 00:51:18,319 high trl now we've we've developed this 1414 00:51:22,069 --> 00:51:20,640 we've done testing over the past uh four 1415 00:51:25,510 --> 00:51:22,079 or five years of ball and we have this 1416 00:51:26,470 --> 00:51:25,520 up around tro5 right now as a as a 1417 00:51:28,630 --> 00:51:26,480 as a 1418 00:51:29,589 --> 00:51:28,640 potential payload for small body body 1419 00:51:31,750 --> 00:51:29,599 missions 1420 00:51:33,670 --> 00:51:31,760 and uh this is you know just one 1421 00:51:34,630 --> 00:51:33,680 scenario that that might play out down 1422 00:51:36,710 --> 00:51:34,640 the bottom here where you have a 1423 00:51:39,349 --> 00:51:36,720 spacecraft in close proximity to a small 1424 00:51:40,790 --> 00:51:39,359 body asteroid in this case 1425 00:51:42,470 --> 00:51:40,800 deploying it off the back end letting it 1426 00:51:43,990 --> 00:51:42,480 free fall down you don't have to make 1427 00:51:46,309 --> 00:51:44,000 this very shock tolerant you know in a 1428 00:51:47,990 --> 00:51:46,319 low g situation it's like dropping your 1429 00:51:49,910 --> 00:51:48,000 pencil from you know about a meter off 1430 00:51:52,630 --> 00:51:49,920 the ground here it'll bounce around the 1431 00:51:54,549 --> 00:51:52,640 surface eventually settle down 1432 00:51:56,230 --> 00:51:54,559 in this particular scenario we were 1433 00:51:58,230 --> 00:51:56,240 using this to try to measure the the 1434 00:51:59,910 --> 00:51:58,240 inherent strength of the object not just 1435 00:52:01,990 --> 00:51:59,920 from the coefficient of restitution from 1436 00:52:04,390 --> 00:52:02,000 from hitting the surface it does have 1437 00:52:06,630 --> 00:52:04,400 accelerometers as a package on this but 1438 00:52:08,630 --> 00:52:06,640 but also by having a small explosive 1439 00:52:11,030 --> 00:52:08,640 charge on it 1440 00:52:13,510 --> 00:52:11,040 to to make a cratering experiment the 1441 00:52:14,710 --> 00:52:13,520 size of the crater is is a direct 1442 00:52:16,390 --> 00:52:14,720 function of what the strength of the 1443 00:52:19,750 --> 00:52:16,400 material is you know the deep impact 1444 00:52:22,390 --> 00:52:19,760 experiment showed that as well uh that 1445 00:52:23,910 --> 00:52:22,400 was one of the premises of it anyway um 1446 00:52:26,150 --> 00:52:23,920 so you know what the size of the crater 1447 00:52:27,750 --> 00:52:26,160 here will inform you a lot about the the 1448 00:52:29,510 --> 00:52:27,760 strength of the material 1449 00:52:30,470 --> 00:52:29,520 is it competent rock or is it a rubble 1450 00:52:31,270 --> 00:52:30,480 pile 1451 00:52:32,470 --> 00:52:31,280 um 1452 00:52:34,470 --> 00:52:32,480 you know this 1453 00:52:35,750 --> 00:52:34,480 but note that there are limitations to 1454 00:52:38,150 --> 00:52:35,760 this you're not going to drop this and 1455 00:52:41,349 --> 00:52:38,160 have one of these spheres be captured in 1456 00:52:44,549 --> 00:52:41,359 a system unless the object is of 1457 00:52:45,910 --> 00:52:44,559 uh you know 100 meters or so or larger 1458 00:52:48,470 --> 00:52:45,920 it's just not going to be a large enough 1459 00:52:50,069 --> 00:52:48,480 gravitational well for it to be captured 1460 00:52:52,309 --> 00:52:50,079 so this is more of a scenario for maybe 1461 00:52:54,069 --> 00:52:52,319 the go grab a rock scenario rather than 1462 00:52:55,109 --> 00:52:54,079 going grabbing the entire entire 1463 00:52:57,510 --> 00:52:55,119 asteroid 1464 00:52:59,670 --> 00:52:57,520 also you know for concepts of it'd be 1465 00:53:01,750 --> 00:52:59,680 nice to have a small free flyer 1466 00:53:03,910 --> 00:53:01,760 something includes maybe a contact probe 1467 00:53:05,829 --> 00:53:03,920 like a little hummingbird to have a 1468 00:53:08,390 --> 00:53:05,839 probiscus to go into touch and go 1469 00:53:10,630 --> 00:53:08,400 surface measurements on the surface 1470 00:53:13,190 --> 00:53:10,640 it also provide a very unique vantage 1471 00:53:14,470 --> 00:53:13,200 point for for imaging the capture 1472 00:53:16,309 --> 00:53:14,480 sequence i think 1473 00:53:18,390 --> 00:53:16,319 you know for for public outreach of this 1474 00:53:20,309 --> 00:53:18,400 would be really nice to have a 1475 00:53:22,950 --> 00:53:20,319 secondary spacecraft watching the entire 1476 00:53:24,470 --> 00:53:22,960 process happen 1477 00:53:26,390 --> 00:53:24,480 so in conclusion 1478 00:53:28,870 --> 00:53:26,400 the arm sensing requirements we see 1479 00:53:31,430 --> 00:53:28,880 being needed for for capture 1480 00:53:33,349 --> 00:53:31,440 one range two pose estimation for a 1481 00:53:35,030 --> 00:53:33,359 resolved target and three high 1482 00:53:36,630 --> 00:53:35,040 resolution visible imaging that's 1483 00:53:37,829 --> 00:53:36,640 actually correlated to that pose 1484 00:53:39,750 --> 00:53:37,839 estimation 1485 00:53:42,390 --> 00:53:39,760 uh those measurements need to be made 1486 00:53:43,670 --> 00:53:42,400 autonomously in real time there are 1487 00:53:45,510 --> 00:53:43,680 mature sensors for making these 1488 00:53:48,549 --> 00:53:45,520 measurements but the software 1489 00:53:50,230 --> 00:53:48,559 is where the development needs to be 1490 00:53:52,470 --> 00:53:50,240 separate flight elements to contact or 1491 00:53:54,069 --> 00:53:52,480 perturb the target surface i think can 1492 00:53:55,270 --> 00:53:54,079 reduce mission risk 1493 00:54:01,589 --> 00:53:55,280 thanks 1494 00:54:05,829 --> 00:54:04,230 we have time for a question for rich if 1495 00:54:08,069 --> 00:54:05,839 in the room 1496 00:54:08,950 --> 00:54:08,079 or virtually 1497 00:54:10,950 --> 00:54:08,960 go ahead 1498 00:54:12,390 --> 00:54:10,960 go to a mic though please 1499 00:54:14,630 --> 00:54:12,400 i can say it really loud how much do 1500 00:54:16,470 --> 00:54:14,640 those surface probes the mass estimates 1501 00:54:18,870 --> 00:54:16,480 for those 1502 00:54:20,230 --> 00:54:18,880 questions yeah the the how much what was 1503 00:54:23,270 --> 00:54:20,240 the mass system up for the surface 1504 00:54:25,270 --> 00:54:23,280 probes um it can vary quite a bit but 1505 00:54:27,109 --> 00:54:25,280 the kind of minimum mass that we see as 1506 00:54:30,630 --> 00:54:27,119 being viable is uh you know on the order 1507 00:54:33,510 --> 00:54:30,640 of five six kilos uh the instantiation 1508 00:54:34,950 --> 00:54:33,520 you saw there had a a couple of kilos of 1509 00:54:36,789 --> 00:54:34,960 actual high explosive on them in 1510 00:54:41,109 --> 00:54:36,799 addition to that so they were they were 1511 00:54:41,119 --> 00:54:44,549 any others 1512 00:54:49,510 --> 00:54:47,349 okay thank you that was a suggestion 1513 00:54:52,309 --> 00:54:49,520 what was the suggestion 1514 00:54:55,190 --> 00:54:52,319 the suggestion was to put an array of 1515 00:54:56,870 --> 00:54:55,200 different sensors and devices 1516 00:55:00,789 --> 00:54:56,880 up and relay the coordinates and 1517 00:55:04,390 --> 00:55:03,030 an array of sensors well actually what 1518 00:55:06,150 --> 00:55:04,400 we were thinking about was an array of 1519 00:55:07,670 --> 00:55:06,160 sensors some of them have geophones on 1520 00:55:09,750 --> 00:55:07,680 them some of them have explosive charges 1521 00:55:12,150 --> 00:55:09,760 you can make a crude seismic network 1522 00:55:14,549 --> 00:55:12,160 that way uh it's hard to place these 1523 00:55:16,390 --> 00:55:14,559 with uh with any control 1524 00:55:18,470 --> 00:55:16,400 so you have to be willing to uh 1525 00:55:20,549 --> 00:55:18,480 to have that uncertainty in the in that 1526 00:55:22,950 --> 00:55:20,559 sensor net but that that is a good 1527 00:55:29,270 --> 00:55:25,910 okay thanks rich 1528 00:55:31,990 --> 00:55:29,280 our next speaker is mark haynes from the 1529 00:55:34,309 --> 00:55:32,000 jet propulsion laboratory 1530 00:55:37,190 --> 00:55:34,319 mark received his phd in applied physics 1531 00:55:39,510 --> 00:55:37,200 from the university of michigan in 2012. 1532 00:55:41,430 --> 00:55:39,520 he joined jpl in june of this year and 1533 00:55:43,030 --> 00:55:41,440 his background is radar 1534 00:55:45,670 --> 00:55:43,040 microwave scattering and inverse 1535 00:55:47,109 --> 00:55:45,680 scattering and medical imaging 1536 00:55:49,030 --> 00:55:47,119 in this presentation he'll give an 1537 00:55:51,109 --> 00:55:49,040 overview of possible applications of 1538 00:55:53,190 --> 00:55:51,119 radar as an asteroid characterization 1539 00:55:55,670 --> 00:55:53,200 and avionics tool 1540 00:55:57,109 --> 00:55:55,680 all right uh good afternoon uh thank you 1541 00:55:58,390 --> 00:55:57,119 for having me 1542 00:56:00,390 --> 00:55:58,400 uh 1543 00:56:02,230 --> 00:56:00,400 like you said um i'm gonna be talking 1544 00:56:04,150 --> 00:56:02,240 about a couple ways in which radar could 1545 00:56:05,430 --> 00:56:04,160 aid future asteroid missions it's a 1546 00:56:06,630 --> 00:56:05,440 pretty general talk there's a lot of 1547 00:56:08,230 --> 00:56:06,640 overlap with some of the other things 1548 00:56:11,270 --> 00:56:08,240 but hopefully we'll generate some more 1549 00:56:12,630 --> 00:56:11,280 detailed discussion later 1550 00:56:14,950 --> 00:56:12,640 so the applications i'm going to talk 1551 00:56:17,030 --> 00:56:14,960 about are aimed at addressing the 1552 00:56:18,870 --> 00:56:17,040 following points of the rfi mostly 1553 00:56:21,430 --> 00:56:18,880 characterization and 1554 00:56:23,589 --> 00:56:21,440 some avionics in general when these 1555 00:56:25,910 --> 00:56:23,599 systems are envisioned as integrated 1556 00:56:27,589 --> 00:56:25,920 sensing systems to be used as an 1557 00:56:29,670 --> 00:56:27,599 avionics tool with the possibility of 1558 00:56:31,349 --> 00:56:29,680 secondary science so real quick just 1559 00:56:33,270 --> 00:56:31,359 some features of radar 1560 00:56:35,030 --> 00:56:33,280 uh it's self-illuminating it works in 1561 00:56:37,990 --> 00:56:35,040 the shadow it can see through dust it's 1562 00:56:39,510 --> 00:56:38,000 very fast it works at a near far range 1563 00:56:41,670 --> 00:56:39,520 and the echoes contain sort of three 1564 00:56:43,430 --> 00:56:41,680 pieces of information how far away you 1565 00:56:45,109 --> 00:56:43,440 are relative motion in the form of 1566 00:56:46,710 --> 00:56:45,119 doppler and then also lots of 1567 00:56:47,349 --> 00:56:46,720 information on the physical scattering 1568 00:56:49,190 --> 00:56:47,359 of 1569 00:56:51,030 --> 00:56:49,200 the body 1570 00:56:52,950 --> 00:56:51,040 so just to give it some context where 1571 00:56:53,990 --> 00:56:52,960 radar has been used in the past 1572 00:56:57,670 --> 00:56:54,000 most everyone's familiar with the 1573 00:56:59,510 --> 00:56:57,680 goldstone arecibo asteroid 1574 00:57:01,589 --> 00:56:59,520 in terms of planetary missions cassini 1575 00:57:03,190 --> 00:57:01,599 magellan had radars that shared the 1576 00:57:05,510 --> 00:57:03,200 communications dish 1577 00:57:07,829 --> 00:57:05,520 there have been three sounding missions 1578 00:57:09,430 --> 00:57:07,839 two to mars mro and mars express and 1579 00:57:11,109 --> 00:57:09,440 then the rosetta concert radar heading 1580 00:57:13,349 --> 00:57:11,119 to the comet 1581 00:57:14,870 --> 00:57:13,359 um 1582 00:57:16,470 --> 00:57:14,880 old mars rovers have gotten where they 1583 00:57:18,630 --> 00:57:16,480 needed to go with the help of landing 1584 00:57:21,109 --> 00:57:18,640 radar and the apollo and shuttle use 1585 00:57:22,870 --> 00:57:21,119 rendezvous radars and to this we can add 1586 00:57:24,150 --> 00:57:22,880 all the earth science remote sensing 1587 00:57:26,870 --> 00:57:24,160 systems 1588 00:57:30,150 --> 00:57:26,880 however for all the asteroid missions to 1589 00:57:31,030 --> 00:57:30,160 date there have been no in-situ radars 1590 00:57:33,270 --> 00:57:31,040 so 1591 00:57:35,030 --> 00:57:33,280 those were or these are primarily 1592 00:57:37,349 --> 00:57:35,040 science missions and so some of the 1593 00:57:38,549 --> 00:57:37,359 aspects of arm and 1594 00:57:40,069 --> 00:57:38,559 other parts of the initiative are a 1595 00:57:42,549 --> 00:57:40,079 little more pragmatic and so a few other 1596 00:57:44,390 --> 00:57:42,559 utilities of radar 1597 00:57:47,270 --> 00:57:44,400 can come out and contribute 1598 00:57:49,589 --> 00:57:47,280 so the first is radar sounding with the 1599 00:57:51,190 --> 00:57:49,599 simple purpose of mapping the regolith 1600 00:57:53,109 --> 00:57:51,200 so this is to get the internal structure 1601 00:57:55,829 --> 00:57:53,119 the bulk dielectric properties and so by 1602 00:57:57,750 --> 00:57:55,839 extension the density distribution 1603 00:57:59,589 --> 00:57:57,760 where to anchor redirect thrusters where 1604 00:58:01,430 --> 00:57:59,599 to pick up samples or possibly boulders 1605 00:58:02,870 --> 00:58:01,440 and of course help improve trajectory 1606 00:58:04,950 --> 00:58:02,880 estimations 1607 00:58:08,470 --> 00:58:04,960 so radar is the only active modality 1608 00:58:09,589 --> 00:58:08,480 capable of subsurface imaging 1609 00:58:11,270 --> 00:58:09,599 and there are two ways you can think 1610 00:58:13,030 --> 00:58:11,280 about doing this what i would call 1611 00:58:14,710 --> 00:58:13,040 scanline projection so this is like 1612 00:58:16,470 --> 00:58:14,720 ground penetrating radar 1613 00:58:18,150 --> 00:58:16,480 and the other is direct conversion so in 1614 00:58:19,910 --> 00:58:18,160 the first case 1615 00:58:22,069 --> 00:58:19,920 this is 1616 00:58:23,510 --> 00:58:22,079 relatively fast it gives you a basic 1617 00:58:25,670 --> 00:58:23,520 anatomy of what you're looking at 1618 00:58:27,589 --> 00:58:25,680 boundaries 1619 00:58:29,910 --> 00:58:27,599 edges this is similar to the way the 1620 00:58:31,910 --> 00:58:29,920 marxist and chirad mars polar images 1621 00:58:33,430 --> 00:58:31,920 were processed 1622 00:58:34,950 --> 00:58:33,440 the second is dielectric conversion so 1623 00:58:35,750 --> 00:58:34,960 for this you voxelize the body you're 1624 00:58:37,109 --> 00:58:35,760 interested in you have an 1625 00:58:38,630 --> 00:58:37,119 electromagnetic scattering model an 1626 00:58:40,710 --> 00:58:38,640 iterative dielectric estimation 1627 00:58:42,069 --> 00:58:40,720 technique and you solve the inverse 1628 00:58:44,309 --> 00:58:42,079 problem 1629 00:58:46,549 --> 00:58:44,319 so this is a little closer to the way 1630 00:58:48,549 --> 00:58:46,559 rosetta concert is going to be working 1631 00:58:49,990 --> 00:58:48,559 and the advantage of this is it gives 1632 00:58:51,829 --> 00:58:50,000 you the actual physical properties of 1633 00:58:53,510 --> 00:58:51,839 the body of interest 1634 00:58:55,349 --> 00:58:53,520 um the depth of penetration and the 1635 00:58:56,549 --> 00:58:55,359 resolution trade off with frequency but 1636 00:58:58,309 --> 00:58:56,559 generally you need a pretty low 1637 00:59:00,470 --> 00:58:58,319 frequency radar to do sounding so we're 1638 00:59:03,109 --> 00:59:00,480 talking hundreds of megahertz or even 1639 00:59:07,030 --> 00:59:04,710 okay so the next application is 1640 00:59:07,829 --> 00:59:07,040 tomography and you can think of this as 1641 00:59:11,589 --> 00:59:07,839 an 1642 00:59:12,950 --> 00:59:11,599 astrotomography is pretty well 1643 00:59:14,549 --> 00:59:12,960 understood 1644 00:59:16,390 --> 00:59:14,559 the echoes that come back contain range 1645 00:59:18,390 --> 00:59:16,400 information as well as doppler in terms 1646 00:59:19,829 --> 00:59:18,400 of what party asteroid is spinning 1647 00:59:21,030 --> 00:59:19,839 towards your way 1648 00:59:22,470 --> 00:59:21,040 you come back in a series of delay 1649 00:59:24,630 --> 00:59:22,480 doppler images these go into a shape 1650 00:59:26,470 --> 00:59:24,640 reconstruction algorithm and out pop the 1651 00:59:28,630 --> 00:59:26,480 size the shape the spin spin axis your 1652 00:59:29,910 --> 00:59:28,640 range of target the relative motion so 1653 00:59:31,670 --> 00:59:29,920 anything you can think to do with that 1654 00:59:33,270 --> 00:59:31,680 information you can get it from 1655 00:59:34,630 --> 00:59:33,280 radiotomography 1656 00:59:36,710 --> 00:59:34,640 the frequencies are generally a little 1657 00:59:37,829 --> 00:59:36,720 bit higher this is for resolution and 1658 00:59:39,990 --> 00:59:37,839 you don't want it to penetrate too 1659 00:59:42,309 --> 00:59:40,000 deeply and it only requires course 1660 00:59:44,230 --> 00:59:42,319 antenna pointing because 1661 00:59:45,510 --> 00:59:44,240 all the information is contained 1662 00:59:46,789 --> 00:59:45,520 in the echoes 1663 00:59:49,589 --> 00:59:46,799 so there are a lot of computing 1664 00:59:52,069 --> 00:59:49,599 technologies for tomography um 1665 00:59:53,910 --> 00:59:52,079 some things that are 1666 00:59:56,390 --> 00:59:53,920 unique maybe to radar 1667 00:59:57,910 --> 00:59:56,400 uh the first is 1668 01:00:00,549 --> 00:59:57,920 using the doppler and sort of 1669 01:00:03,030 --> 01:00:00,559 differential mode so to reassess rates 1670 01:00:05,030 --> 01:00:03,040 of change of spin due to deflection or 1671 01:00:07,270 --> 01:00:05,040 what have you 1672 01:00:09,750 --> 01:00:07,280 and the second this one's kind of new 1673 01:00:12,789 --> 01:00:09,760 it's to use delay doppler images as a 1674 01:00:14,630 --> 01:00:12,799 form of gps proxy so if you want to give 1675 01:00:16,630 --> 01:00:14,640 the spacecraft a better idea of where it 1676 01:00:18,230 --> 01:00:16,640 was you turn the radar on the body you 1677 01:00:19,750 --> 01:00:18,240 take a couple echoes and you go to a 1678 01:00:22,150 --> 01:00:19,760 table look up and you say okay now here 1679 01:00:23,430 --> 01:00:22,160 i am relative to the body and the 1680 01:00:25,670 --> 01:00:23,440 advantage is this is a direct 1681 01:00:28,630 --> 01:00:25,680 measurement and um 1682 01:00:30,789 --> 01:00:28,640 relatively fast 1683 01:00:32,309 --> 01:00:30,799 so this is the grab bag slide this has 1684 01:00:34,630 --> 01:00:32,319 some other uh 1685 01:00:37,670 --> 01:00:34,640 some overlap with some other sessions 1686 01:00:40,470 --> 01:00:37,680 so if they're gonna be multiple crafts 1687 01:00:41,990 --> 01:00:40,480 moving around rendezvous radar is 1688 01:00:43,510 --> 01:00:42,000 something to use i think the idea would 1689 01:00:46,390 --> 01:00:43,520 be to try to integrate it maybe with the 1690 01:00:48,309 --> 01:00:46,400 sounding radar to save on hardware 1691 01:00:50,230 --> 01:00:48,319 if you have a radar you can always use 1692 01:00:52,230 --> 01:00:50,240 it for altimetry and landing 1693 01:00:54,230 --> 01:00:52,240 the caveat of course in microgravity 1694 01:00:56,870 --> 01:00:54,240 with low velocities 1695 01:00:57,670 --> 01:00:56,880 is that laser rangefinders do just fine 1696 01:01:00,069 --> 01:00:57,680 um 1697 01:01:02,069 --> 01:01:00,079 but you can always use this as a backup 1698 01:01:03,510 --> 01:01:02,079 uh the next uh these two applications 1699 01:01:07,030 --> 01:01:03,520 are sort of 1700 01:01:08,710 --> 01:01:07,040 deflection rather than redirection 1701 01:01:09,990 --> 01:01:08,720 so you have two spacecraft one orbiting 1702 01:01:12,870 --> 01:01:10,000 the body another one that's going to hit 1703 01:01:14,390 --> 01:01:12,880 it you can use the delay doppler and get 1704 01:01:15,910 --> 01:01:14,400 a better sense of how it's now spinning 1705 01:01:17,349 --> 01:01:15,920 or how it's now moving 1706 01:01:18,789 --> 01:01:17,359 the advantage is it could look through 1707 01:01:20,789 --> 01:01:18,799 the ejecta and it can maybe even track 1708 01:01:23,109 --> 01:01:20,799 the ejecta 1709 01:01:24,950 --> 01:01:23,119 and finally 1710 01:01:25,990 --> 01:01:24,960 so this is this is a little different a 1711 01:01:28,470 --> 01:01:26,000 little new 1712 01:01:31,430 --> 01:01:28,480 uh this is a case of uh a single 1713 01:01:33,109 --> 01:01:31,440 spacecraft based uh redeflection impact 1714 01:01:33,990 --> 01:01:33,119 base reflection 1715 01:01:35,430 --> 01:01:34,000 uh 1716 01:01:36,950 --> 01:01:35,440 so let's say you're three to four days 1717 01:01:38,390 --> 01:01:36,960 out from the body you turn the comm 1718 01:01:40,069 --> 01:01:38,400 antenna on the asteroid 1719 01:01:41,910 --> 01:01:40,079 you do the tomography problem 1720 01:01:45,670 --> 01:01:41,920 give the craft an idea of 1721 01:01:49,670 --> 01:01:45,680 where and when exactly it's going to hit 1722 01:01:53,270 --> 01:01:51,670 okay in terms of system configurations 1723 01:01:55,190 --> 01:01:53,280 uh to do tomography and sounding you 1724 01:01:56,470 --> 01:01:55,200 actually only need one antenna which is 1725 01:01:57,829 --> 01:01:56,480 uh kind of nice 1726 01:02:00,069 --> 01:01:57,839 for sounding though it needs its own 1727 01:02:01,349 --> 01:02:00,079 separate low frequency antenna 1728 01:02:02,789 --> 01:02:01,359 um 1729 01:02:04,470 --> 01:02:02,799 if you double up on the communication 1730 01:02:06,549 --> 01:02:04,480 dish you'll be at the higher frequencies 1731 01:02:09,190 --> 01:02:06,559 probably of the dsn and so you're 1732 01:02:11,270 --> 01:02:09,200 limited to some of those applications 1733 01:02:13,990 --> 01:02:11,280 in terms of power what you need to run 1734 01:02:16,710 --> 01:02:14,000 these systems it just goes with range 1735 01:02:19,349 --> 01:02:16,720 to give you some examples 1736 01:02:21,750 --> 01:02:19,359 earth observing radars typically operate 1737 01:02:24,309 --> 01:02:21,760 in one kilowatt peak power range 1738 01:02:25,670 --> 01:02:24,319 airborne systems 10 watts um and if 1739 01:02:27,910 --> 01:02:25,680 you're really close for whatever reason 1740 01:02:29,349 --> 01:02:27,920 you could use your cell phone 1741 01:02:30,390 --> 01:02:29,359 and so 1742 01:02:32,390 --> 01:02:30,400 uh 1743 01:02:34,309 --> 01:02:32,400 scanline sounding ultimate retargeting 1744 01:02:36,230 --> 01:02:34,319 and some tomography there are candidates 1745 01:02:37,589 --> 01:02:36,240 for onboard processing uh direct 1746 01:02:38,870 --> 01:02:37,599 conversion and more sophisticated 1747 01:02:40,390 --> 01:02:38,880 demography are probably gonna have to be 1748 01:02:42,390 --> 01:02:40,400 sent back 1749 01:02:43,270 --> 01:02:42,400 and um i'll just wrap this up by saying 1750 01:02:44,630 --> 01:02:43,280 that 1751 01:02:45,589 --> 01:02:44,640 you know electromagnetic scattering 1752 01:02:50,630 --> 01:02:45,599 models 1753 01:02:52,230 --> 01:02:50,640 have gotten to the point where we can 1754 01:02:56,470 --> 01:02:52,240 actually simulate these systems end to 1755 01:02:57,990 --> 01:02:56,480 end before turning a screw and so we can 1756 01:02:59,670 --> 01:02:58,000 tweak the frequencies really assess 1757 01:03:03,589 --> 01:02:59,680 whether or not they're going to work at 1758 01:03:07,670 --> 01:03:05,349 so that's it again these applications 1759 01:03:10,870 --> 01:03:07,680 were mostly uh characterization and 1760 01:03:18,390 --> 01:03:10,880 avionics based and 1761 01:03:18,400 --> 01:03:28,069 okay we've got time for questions 1762 01:03:34,870 --> 01:03:31,349 see any online although we are delayed a 1763 01:03:34,880 --> 01:03:38,870 yep i got one 1764 01:03:42,549 --> 01:03:40,710 is there is there any advantage of 1765 01:03:44,950 --> 01:03:42,559 having a lot of power you know you said 1766 01:03:46,630 --> 01:03:44,960 a kilowatt from earth orbiting systems 1767 01:03:48,789 --> 01:03:46,640 but we're gonna have a spacecraft that 1768 01:03:51,349 --> 01:03:48,799 might have a lot of power 1769 01:03:52,549 --> 01:03:51,359 will that provide you any advantages oh 1770 01:03:53,670 --> 01:03:52,559 yeah 1771 01:03:56,390 --> 01:03:53,680 um 1772 01:03:58,789 --> 01:03:56,400 uh snr it will always help 1773 01:04:00,950 --> 01:03:58,799 and then you can just do these um 1774 01:04:03,910 --> 01:04:00,960 you can have much uh higher orbits you 1775 01:04:13,349 --> 01:04:03,920 can do the same work much further away 1776 01:04:16,710 --> 01:04:14,950 all right thank you 1777 01:04:18,390 --> 01:04:16,720 all right let's see 1778 01:04:19,270 --> 01:04:18,400 we got to check um 1779 01:04:22,069 --> 01:04:19,280 we 1780 01:04:26,069 --> 01:04:22,079 had intended the next presenter to be um 1781 01:04:26,079 --> 01:04:32,230 is 1782 01:04:35,190 --> 01:04:33,510 okay great 1783 01:04:38,069 --> 01:04:35,200 thank you 1784 01:04:43,470 --> 01:04:40,870 paul is a project manager for mda 1785 01:04:45,990 --> 01:04:43,480 mda of course is the uh 1786 01:04:47,510 --> 01:04:46,000 macdonald associates is the canadian 1787 01:04:50,309 --> 01:04:47,520 space agency prime contractor for 1788 01:04:52,549 --> 01:04:50,319 robotics on space shuttle and iss 1789 01:04:53,910 --> 01:04:52,559 paul will be discussing how the arm can 1790 01:04:55,349 --> 01:04:53,920 benefit from state-of-the-art 1791 01:04:57,750 --> 01:04:55,359 developments in the area of rendezvous 1792 01:05:00,549 --> 01:04:57,760 and proxima proximity operations and in 1793 01:05:02,870 --> 01:05:00,559 satellite servicing domains well 1794 01:05:05,190 --> 01:05:02,880 okay thank you everybody um so we 1795 01:05:06,630 --> 01:05:05,200 started off uh looking at this problem 1796 01:05:08,950 --> 01:05:06,640 we had a good time by the way looking at 1797 01:05:11,750 --> 01:05:08,960 this problem but we broke it down the 1798 01:05:13,829 --> 01:05:11,760 same way we would break down any 1799 01:05:14,789 --> 01:05:13,839 satellite operation that we've done in 1800 01:05:16,789 --> 01:05:14,799 the past 1801 01:05:19,349 --> 01:05:16,799 so we broke it down into rendezvous 1802 01:05:20,950 --> 01:05:19,359 proximity operations and capture 1803 01:05:23,109 --> 01:05:20,960 today's presentation is on the 1804 01:05:24,470 --> 01:05:23,119 rendezvous and the proximity operations 1805 01:05:27,829 --> 01:05:24,480 and tomorrow i will be giving a 1806 01:05:33,109 --> 01:05:30,950 so just to give a very quick overview 1807 01:05:35,349 --> 01:05:33,119 mda has been focused on these type of 1808 01:05:37,750 --> 01:05:35,359 activities for decades 1809 01:05:40,470 --> 01:05:37,760 so it started back in the 70s with the 1810 01:05:42,309 --> 01:05:40,480 development of canadarm or srms for the 1811 01:05:43,190 --> 01:05:42,319 shuttle program 1812 01:05:44,470 --> 01:05:43,200 and 1813 01:05:45,670 --> 01:05:44,480 includes 1814 01:05:47,510 --> 01:05:45,680 significant 1815 01:05:48,950 --> 01:05:47,520 rendezvous and capture of the hubble 1816 01:05:51,670 --> 01:05:48,960 space telescope 1817 01:05:54,150 --> 01:05:51,680 four times from from the shuttle 1818 01:05:57,910 --> 01:05:54,160 we've also actually captured the shuttle 1819 01:05:59,510 --> 01:05:57,920 from station using canadarm2 as well 1820 01:06:01,430 --> 01:05:59,520 then we've done different developments 1821 01:06:03,430 --> 01:06:01,440 and i'll echo some of the sentiments of 1822 01:06:04,470 --> 01:06:03,440 other folks here but we 1823 01:06:07,990 --> 01:06:04,480 provided 1824 01:06:09,910 --> 01:06:08,000 scanning lidar systems for xss-11 1825 01:06:13,750 --> 01:06:09,920 and the robotic 1826 01:06:15,910 --> 01:06:13,760 autonomous systems for orbital express 1827 01:06:17,910 --> 01:06:15,920 in recent times the canadian space 1828 01:06:20,309 --> 01:06:17,920 agency has invested over 50 million 1829 01:06:22,950 --> 01:06:20,319 dollars in in prototyping for what they 1830 01:06:26,870 --> 01:06:22,960 call the next generation canadarm 1831 01:06:31,270 --> 01:06:26,880 and in all of that it uh it has included 1832 01:06:33,990 --> 01:06:31,280 rendezvous and proximity operations 1833 01:06:35,430 --> 01:06:34,000 so so just to draw the parallels and i 1834 01:06:38,470 --> 01:06:35,440 know that everybody's walked through 1835 01:06:40,470 --> 01:06:38,480 this as well the the typical operational 1836 01:06:42,069 --> 01:06:40,480 steps include long range and short range 1837 01:06:44,470 --> 01:06:42,079 rendezvous 1838 01:06:47,829 --> 01:06:44,480 scanning and mapping rate matching close 1839 01:06:50,230 --> 01:06:47,839 proximity operations etc 1840 01:06:51,910 --> 01:06:50,240 and uh just on the right we're showing 1841 01:06:54,470 --> 01:06:51,920 some of the heritage that we have in 1842 01:06:57,190 --> 01:06:54,480 addressing that 1843 01:06:58,230 --> 01:06:57,200 so for the next section uh on the 1844 01:06:59,589 --> 01:06:58,240 integrated 1845 01:07:02,069 --> 01:06:59,599 sensor suite 1846 01:07:04,230 --> 01:07:02,079 uh focus on on these aspects of the 1847 01:07:06,069 --> 01:07:04,240 conops 1848 01:07:07,670 --> 01:07:06,079 so 1849 01:07:10,630 --> 01:07:07,680 i i believe the gentleman from ball 1850 01:07:12,069 --> 01:07:10,640 aerospace had almost the exact same uh 1851 01:07:13,589 --> 01:07:12,079 instrument suite which i think is good 1852 01:07:15,190 --> 01:07:13,599 we're starting to synthesize we're all 1853 01:07:18,230 --> 01:07:15,200 starting to come together 1854 01:07:20,950 --> 01:07:18,240 what we were proposing was for far field 1855 01:07:22,470 --> 01:07:20,960 long range to have a narrow angle 1856 01:07:24,390 --> 01:07:22,480 camera 1857 01:07:26,470 --> 01:07:24,400 that picks up bearing information and 1858 01:07:28,710 --> 01:07:26,480 then as you get closer you actually 1859 01:07:32,150 --> 01:07:28,720 combine the narrow angle camera with a 1860 01:07:34,549 --> 01:07:32,160 lidar and the laser altimeter that mda 1861 01:07:37,349 --> 01:07:34,559 is developing for osiris-rex would be 1862 01:07:39,510 --> 01:07:37,359 coupled with the narrow angle camera 1863 01:07:41,430 --> 01:07:39,520 which would give you bearing and range 1864 01:07:44,069 --> 01:07:41,440 and then as you get closer you'd have a 1865 01:07:45,510 --> 01:07:44,079 wider angle camera 1866 01:07:47,589 --> 01:07:45,520 that begins to give you detailed 1867 01:07:49,829 --> 01:07:47,599 features of the asteroid and then that 1868 01:07:52,549 --> 01:07:49,839 would be coupled with flashlighter 1869 01:07:53,990 --> 01:07:52,559 and mda has been doing work 1870 01:07:56,309 --> 01:07:54,000 similar to 1871 01:07:57,670 --> 01:07:56,319 slam or simultaneous localization and 1872 01:07:59,029 --> 01:07:57,680 mapping 1873 01:08:01,190 --> 01:07:59,039 we have 1874 01:08:05,109 --> 01:08:01,200 two coupled 1875 01:08:07,270 --> 01:08:05,119 phonak robots in a lab where we 1876 01:08:08,789 --> 01:08:07,280 basically generate models using 1877 01:08:11,430 --> 01:08:08,799 three-dimensional and two-dimensional 1878 01:08:13,510 --> 01:08:11,440 data we generate those models we port 1879 01:08:17,910 --> 01:08:13,520 them back and use the models to do close 1880 01:08:21,510 --> 01:08:19,430 also following down the concept of 1881 01:08:23,829 --> 01:08:21,520 operations to look at close proximity 1882 01:08:26,149 --> 01:08:23,839 capture and autonomy 1883 01:08:28,630 --> 01:08:26,159 mda has done a lot of work not only in 1884 01:08:30,550 --> 01:08:28,640 orbital robotics but also in rover 1885 01:08:32,709 --> 01:08:30,560 systems 1886 01:08:34,070 --> 01:08:32,719 and 1887 01:08:35,910 --> 01:08:34,080 just to give you an idea of the state of 1888 01:08:37,829 --> 01:08:35,920 the arts so on the international space 1889 01:08:39,430 --> 01:08:37,839 station right now there's the dexter 1890 01:08:41,590 --> 01:08:39,440 robot or what we call the special 1891 01:08:43,430 --> 01:08:41,600 purpose dexterous manipulator 1892 01:08:44,229 --> 01:08:43,440 and canadarm2 1893 01:08:46,229 --> 01:08:44,239 and 1894 01:08:48,149 --> 01:08:46,239 those 1895 01:08:50,309 --> 01:08:48,159 robots are currently being operated from 1896 01:08:52,470 --> 01:08:50,319 the ground so to give an idea of where 1897 01:08:53,910 --> 01:08:52,480 it's come to originally they had to have 1898 01:08:57,030 --> 01:08:53,920 the operator in the loop in close 1899 01:08:58,550 --> 01:08:57,040 proximity now the ground crew is at 1900 01:09:01,669 --> 01:08:58,560 johnson space center or the canadian 1901 01:09:03,590 --> 01:09:01,679 space agency the astronauts are asleep 1902 01:09:06,470 --> 01:09:03,600 and they they begin to go and do all 1903 01:09:10,309 --> 01:09:06,480 these dexterous tasks 1904 01:09:13,189 --> 01:09:10,319 at uh goddard also mentioned the rrm 1905 01:09:14,950 --> 01:09:13,199 mission or the robotic refueling mission 1906 01:09:17,189 --> 01:09:14,960 uh that focused on unprepared and 1907 01:09:20,550 --> 01:09:17,199 uncooperative capture 1908 01:09:23,189 --> 01:09:20,560 fill and drain valve refueling and mli 1909 01:09:25,189 --> 01:09:23,199 blanket removal and again all of those 1910 01:09:27,349 --> 01:09:25,199 all of those tasks were done 1911 01:09:28,550 --> 01:09:27,359 with a 15 degree of freedom manipulator 1912 01:09:29,749 --> 01:09:28,560 on the end of 1913 01:09:31,590 --> 01:09:29,759 a 1914 01:09:34,229 --> 01:09:31,600 30 foot long 1915 01:09:36,390 --> 01:09:34,239 canadarm2 operated from the ground all 1916 01:09:38,470 --> 01:09:36,400 happening successfully 1917 01:09:41,269 --> 01:09:38,480 mda has also been looking at low 1918 01:09:43,030 --> 01:09:41,279 bandwidth high latency situations 1919 01:09:44,870 --> 01:09:43,040 and we've had a variety of contracts 1920 01:09:47,189 --> 01:09:44,880 with the canadian space agency looking 1921 01:09:49,590 --> 01:09:47,199 at variable autonomy and variable 1922 01:09:53,030 --> 01:09:49,600 autonomy we consider it a spectrum 1923 01:09:54,709 --> 01:09:53,040 and it ranges from teleoperation to 1924 01:09:57,030 --> 01:09:54,719 rigorous rehearsed 1925 01:09:58,390 --> 01:09:57,040 scripted operations to supervised 1926 01:10:00,630 --> 01:09:58,400 autonomy 1927 01:10:02,709 --> 01:10:00,640 not dissimilar to how the curiosity 1928 01:10:05,350 --> 01:10:02,719 rover landed on mars that there comes a 1929 01:10:07,270 --> 01:10:05,360 point where operator in the loop does no 1930 01:10:09,110 --> 01:10:07,280 longer make sense 1931 01:10:10,870 --> 01:10:09,120 via ground control we've actually 1932 01:10:13,350 --> 01:10:10,880 demonstrated this in conjunction with 1933 01:10:15,030 --> 01:10:13,360 boeing for orbital express 1934 01:10:17,590 --> 01:10:15,040 where the manipulator 1935 01:10:21,910 --> 01:10:17,600 close the loop with cameras as the 1936 01:10:26,790 --> 01:10:23,910 and i don't have a concluding slide just 1937 01:10:32,630 --> 01:10:26,800 for the sake of time 1938 01:10:36,310 --> 01:10:35,350 um we have time for questions 1939 01:10:39,030 --> 01:10:36,320 if 1940 01:10:40,709 --> 01:10:39,040 any in the room or virtually 1941 01:10:43,189 --> 01:10:40,719 there is a question here 1942 01:10:44,870 --> 01:10:43,199 why uh the user sorry 1943 01:10:47,030 --> 01:10:44,880 why the use of both a scanning and a 1944 01:11:06,390 --> 01:10:47,040 flash lighter 1945 01:11:09,830 --> 01:11:08,470 it gives you 1946 01:11:12,149 --> 01:11:09,840 your six degrees of freedom 1947 01:11:14,229 --> 01:11:12,159 instantaneous estimation similar to that 1948 01:11:16,390 --> 01:11:14,239 of a video camera 1949 01:11:17,750 --> 01:11:16,400 and then you you match that model with 1950 01:11:20,630 --> 01:11:17,760 the model that you've 1951 01:11:22,149 --> 01:11:20,640 created using your your laser altimeter 1952 01:11:31,430 --> 01:11:22,159 or your scanning ladder 1953 01:11:34,790 --> 01:11:33,510 i don't think i can answer that 1954 01:11:38,390 --> 01:11:34,800 i don't think i'm able to answer that 1955 01:11:38,400 --> 01:11:43,510 go ahead if you could go to a mic please 1956 01:11:49,110 --> 01:11:45,830 it's a quick one uh no one so far has 1957 01:11:51,669 --> 01:11:49,120 mentioned the use of automotive radars 1958 01:11:55,030 --> 01:11:51,679 in the rendezvous but tyvac were funded 1959 01:11:56,870 --> 01:11:55,040 to do this under the edison call last 1960 01:12:03,750 --> 01:11:56,880 year i believe and it seems like it's a 1961 01:12:07,030 --> 01:12:05,990 automotive radars uh 1962 01:12:12,229 --> 01:12:07,040 i'm 1963 01:12:14,390 --> 01:12:12,239 to that anyone else want to come in yes 1964 01:12:19,430 --> 01:12:14,400 really high frequencies if you could go 1965 01:12:23,750 --> 01:12:21,590 automotive radars uh they tend to work 1966 01:12:25,270 --> 01:12:23,760 it who asks the question 1967 01:12:26,229 --> 01:12:25,280 anyway sorry 1968 01:12:27,910 --> 01:12:26,239 they tend to work at really high 1969 01:12:29,350 --> 01:12:27,920 frequencies and so they're you know 1970 01:12:30,790 --> 01:12:29,360 expensive and 1971 01:12:32,470 --> 01:12:30,800 but um 1972 01:12:34,149 --> 01:12:32,480 but uh the rendezvous is mostly in the 1973 01:12:35,750 --> 01:12:34,159 protocol i think a lot of that so you 1974 01:12:40,310 --> 01:12:35,760 can still use the antennas and still use 1975 01:12:50,149 --> 01:12:42,390 anything else 1976 01:12:56,229 --> 01:12:52,870 david gump is our next speaker 1977 01:12:58,550 --> 01:12:56,239 david is ceo of deep space industries 1978 01:13:00,310 --> 01:12:58,560 dsi is focusing on low-cost scouting 1979 01:13:01,830 --> 01:13:00,320 missions to characterize asteroid 1980 01:13:03,110 --> 01:13:01,840 resources 1981 01:13:05,030 --> 01:13:03,120 and developing and parallel the 1982 01:13:07,270 --> 01:13:05,040 technologies to process asteroid 1983 01:13:09,189 --> 01:13:07,280 material into useful products 1984 01:13:11,590 --> 01:13:09,199 his presentation outlines reasons for 1985 01:13:13,350 --> 01:13:11,600 replacing the textile return of a small 1986 01:13:16,390 --> 01:13:13,360 asteroid with a mission that returns 1987 01:13:17,669 --> 01:13:16,400 multiple samples from a larger target 1988 01:13:20,070 --> 01:13:17,679 the goal is achievement of better 1989 01:13:21,910 --> 01:13:20,080 results for both science and industry 1990 01:13:24,390 --> 01:13:21,920 while reducing several types of mission 1991 01:13:28,709 --> 01:13:26,630 thank you 1992 01:13:31,669 --> 01:13:28,719 the textile approach the baseline that 1993 01:13:33,350 --> 01:13:31,679 nasa has now i think has unacceptable 1994 01:13:35,750 --> 01:13:33,360 risk for 1995 01:13:38,149 --> 01:13:35,760 failure because if all you're going on 1996 01:13:39,590 --> 01:13:38,159 is the magnitude 1997 01:13:44,070 --> 01:13:39,600 the 1998 01:13:45,990 --> 01:13:44,080 for say 200 tons return could encounter 1999 01:13:47,990 --> 01:13:46,000 very easily something at 500 tons or a 2000 01:13:50,390 --> 01:13:48,000 thousand tons 2001 01:13:52,070 --> 01:13:50,400 even if your target has been 2002 01:13:54,390 --> 01:13:52,080 considerate and actually flown by earth 2003 01:13:57,669 --> 01:13:54,400 for a rater observation you still only 2004 01:13:58,790 --> 01:13:57,679 know volume you don't know mass 2005 01:14:00,229 --> 01:13:58,800 the other point i'd like to make during 2006 01:14:02,390 --> 01:14:00,239 the presentation is that scouting 2007 01:14:04,390 --> 01:14:02,400 missions are really essential to bring 2008 01:14:06,550 --> 01:14:04,400 down mass uncertainty as well as other 2009 01:14:08,790 --> 01:14:06,560 uncertainties 2010 01:14:10,790 --> 01:14:08,800 we also believe that 2011 01:14:11,750 --> 01:14:10,800 you ought to be fishing where the fish 2012 01:14:13,830 --> 01:14:11,760 are 2013 01:14:16,470 --> 01:14:13,840 you know the vast majority of asteroids 2014 01:14:19,270 --> 01:14:16,480 are not seven meters in size 2015 01:14:21,270 --> 01:14:19,280 and for repeatability and sustainability 2016 01:14:23,990 --> 01:14:21,280 you ought to have a gathering of 2017 01:14:27,350 --> 01:14:24,000 materials approach which is applicable 2018 01:14:29,189 --> 01:14:27,360 to a vast range of asteroid sizes not 2019 01:14:31,189 --> 01:14:29,199 just the special case 2020 01:14:33,590 --> 01:14:31,199 and besides this just easier and we 2021 01:14:36,070 --> 01:14:33,600 ought to be going easier on this than 2022 01:14:37,669 --> 01:14:36,080 making our life hard to detect 2023 01:14:39,189 --> 01:14:37,679 to get enough photons to actually do 2024 01:14:41,430 --> 01:14:39,199 characterization 2025 01:14:43,030 --> 01:14:41,440 when you're out in the deep dark 2026 01:14:44,630 --> 01:14:43,040 people have already pointed out that 2027 01:14:47,510 --> 01:14:44,640 it's going to be hard to actually 2028 01:14:49,430 --> 01:14:47,520 acquire for closing the target if it's 2029 01:14:50,790 --> 01:14:49,440 an extremely tiny one 2030 01:14:53,189 --> 01:14:50,800 large 2031 01:14:54,630 --> 01:14:53,199 neos are easier to land on because they 2032 01:14:57,350 --> 01:14:54,640 spin slower 2033 01:14:59,830 --> 01:14:57,360 and perhaps most importantly 2034 01:15:02,390 --> 01:14:59,840 congress your customer has said they are 2035 01:15:04,229 --> 01:15:02,400 interested in medium and large asteroids 2036 01:15:07,990 --> 01:15:04,239 things big enough to kill their 2037 01:15:11,189 --> 01:15:09,590 they want them both detected and 2038 01:15:12,390 --> 01:15:11,199 characterized which scouting missions 2039 01:15:13,990 --> 01:15:12,400 can do 2040 01:15:16,310 --> 01:15:14,000 we don't have any photographs of things 2041 01:15:18,790 --> 01:15:16,320 a little smaller than 500 meters 2042 01:15:21,110 --> 01:15:18,800 and so we don't know if they do in fact 2043 01:15:23,510 --> 01:15:21,120 transition from rubble piles down to 2044 01:15:25,669 --> 01:15:23,520 monoliths or whether they stay monoliths 2045 01:15:27,590 --> 01:15:25,679 down stay rubble piles down to smaller 2046 01:15:31,990 --> 01:15:27,600 sizes 2047 01:15:35,830 --> 01:15:32,000 angeles or you know really mess with 2048 01:15:40,550 --> 01:15:38,630 so we think in general terms because of 2049 01:15:43,110 --> 01:15:40,560 all these questions you ought to design 2050 01:15:44,870 --> 01:15:43,120 the program both for the retrieval 2051 01:15:47,270 --> 01:15:44,880 mission and for scouting missions before 2052 01:15:48,229 --> 01:15:47,280 you leap into designing a specific 2053 01:15:49,990 --> 01:15:48,239 mission 2054 01:15:52,709 --> 01:15:50,000 and there ought to be demonstrated a 2055 01:15:55,750 --> 01:15:52,719 method that's generally useful and not 2056 01:15:58,390 --> 01:15:55,760 limited to rare situations of of small 2057 01:15:59,590 --> 01:15:58,400 asteroids coupled with a billion dollar 2058 01:16:01,990 --> 01:15:59,600 sls 2059 01:16:03,270 --> 01:16:02,000 that is not a sustainable approach we 2060 01:16:05,110 --> 01:16:03,280 don't believe 2061 01:16:06,950 --> 01:16:05,120 we think the basic program that we would 2062 01:16:09,430 --> 01:16:06,960 propose would be modeled on cots you've 2063 01:16:12,149 --> 01:16:09,440 now got two successful cuts 2064 01:16:15,590 --> 01:16:12,159 systems in operation as well as the the 2065 01:16:17,350 --> 01:16:15,600 iled that nasa has a in place for the 2066 01:16:19,110 --> 01:16:17,360 google lunar xprize 2067 01:16:21,350 --> 01:16:19,120 competitors 2068 01:16:22,950 --> 01:16:21,360 very simple you do fixed price and below 2069 01:16:24,070 --> 01:16:22,960 cost so there has to be private 2070 01:16:26,229 --> 01:16:24,080 investment 2071 01:16:28,390 --> 01:16:26,239 companies competing companies get paid 2072 01:16:29,430 --> 01:16:28,400 for achieving milestones and not just 2073 01:16:31,350 --> 01:16:29,440 submitting 2074 01:16:34,470 --> 01:16:31,360 monthly invoices 2075 01:16:37,030 --> 01:16:34,480 nasa would specify what it needs for its 2076 01:16:39,350 --> 01:16:37,040 applications and its needs and industry 2077 01:16:41,990 --> 01:16:39,360 would fund the delta for everything else 2078 01:16:43,030 --> 01:16:42,000 in the fullness of time most likely 2079 01:16:44,630 --> 01:16:43,040 on a 2080 01:16:46,229 --> 01:16:44,640 nasa would be 2081 01:16:48,550 --> 01:16:46,239 forced through budget 2082 01:16:51,030 --> 01:16:48,560 requirements to go for a disposable 2083 01:16:53,350 --> 01:16:51,040 spacecraft 2084 01:16:56,070 --> 01:16:53,360 industry to serve commercial needs 2085 01:16:58,630 --> 01:16:56,080 ongoing wants a reusable spacecraft 2086 01:17:01,510 --> 01:16:58,640 industry would pay for the delta between 2087 01:17:03,430 --> 01:17:01,520 what's required to support nasa's needs 2088 01:17:05,030 --> 01:17:03,440 and what's necessary for commercial 2089 01:17:06,950 --> 01:17:05,040 markets 2090 01:17:08,950 --> 01:17:06,960 and the resulting system then is 2091 01:17:11,110 --> 01:17:08,960 sustainable it's in place it's serving 2092 01:17:13,910 --> 01:17:11,120 commercial customers for propellant and 2093 01:17:16,709 --> 01:17:13,920 for materials in orbit if there's a year 2094 01:17:19,110 --> 01:17:16,719 or two pause in nasa funding for for 2095 01:17:23,430 --> 01:17:19,120 asteroid missions nothing comes to a 2096 01:17:28,550 --> 01:17:25,669 another good thing about the gather 2097 01:17:30,709 --> 01:17:28,560 materials approach is that the arv size 2098 01:17:32,870 --> 01:17:30,719 is independent of the asteroid size you 2099 01:17:34,470 --> 01:17:32,880 could do smaller arvs 2100 01:17:35,590 --> 01:17:34,480 in the early days to reduce mission 2101 01:17:37,270 --> 01:17:35,600 costs 2102 01:17:39,189 --> 01:17:37,280 and the collection process can be 2103 01:17:40,870 --> 01:17:39,199 selective 2104 01:17:42,950 --> 01:17:40,880 there are different colored boulders on 2105 01:17:45,110 --> 01:17:42,960 iroquois hitacaba for example you might 2106 01:17:46,870 --> 01:17:45,120 want to go for a specific color you 2107 01:17:49,110 --> 01:17:46,880 might want to go for sand and gravel 2108 01:17:51,430 --> 01:17:49,120 because the processing step that you're 2109 01:17:53,189 --> 01:17:51,440 going to bring it back to put it into 2110 01:17:55,510 --> 01:17:53,199 would like it already crushed you can 2111 01:17:57,590 --> 01:17:55,520 gather the already crushed materials if 2112 01:17:59,910 --> 01:17:57,600 you've developed at the beginning a 2113 01:18:01,669 --> 01:17:59,920 gathering of materials approach as to as 2114 01:18:03,830 --> 01:18:01,679 opposed to a swallowing of an asteroid 2115 01:18:06,149 --> 01:18:03,840 approach 2116 01:18:08,550 --> 01:18:06,159 we believe scouting missions can 2117 01:18:11,350 --> 01:18:08,560 collectively among them deliver 2118 01:18:12,550 --> 01:18:11,360 as much material as orion's 100 kilogram 2119 01:18:14,630 --> 01:18:12,560 return limit 2120 01:18:16,229 --> 01:18:14,640 and to be coming from diverse sources 2121 01:18:18,229 --> 01:18:16,239 better for scientists better for 2122 01:18:20,149 --> 01:18:18,239 resource discovery 2123 01:18:21,830 --> 01:18:20,159 you know you'll get much richer data 2124 01:18:24,790 --> 01:18:21,840 from that kind of approach to supplying 2125 01:18:28,070 --> 01:18:24,800 things for the orion sls flight 2126 01:18:30,630 --> 01:18:28,080 we've done some of the initial math 2127 01:18:32,310 --> 01:18:30,640 on this chart the vertical is kilometers 2128 01:18:34,070 --> 01:18:32,320 per second delta v 2129 01:18:36,229 --> 01:18:34,080 we've found as a rule of thumb the 2130 01:18:39,350 --> 01:18:36,239 outbound delta v and the inbound return 2131 01:18:42,550 --> 01:18:39,360 delta v are roughly the same 2132 01:18:46,630 --> 01:18:42,560 this is starting from uh c3 of zero when 2133 01:18:50,470 --> 01:18:48,229 you could launch a scout mission with 2134 01:18:52,790 --> 01:18:50,480 that first arrow in 2015 2135 01:18:54,390 --> 01:18:52,800 it would get there a year later in 2016 2136 01:18:57,350 --> 01:18:54,400 at the second area you gather some 2137 01:18:59,510 --> 01:18:57,360 material you get back a year later in in 2138 01:19:01,590 --> 01:18:59,520 2017 2139 01:19:03,750 --> 01:19:01,600 and then you have a full year to analyze 2140 01:19:05,830 --> 01:19:03,760 that material before you have to launch 2141 01:19:08,390 --> 01:19:05,840 the retrieval mission with only about 2142 01:19:10,550 --> 01:19:08,400 two kilometers per second required it 2143 01:19:12,470 --> 01:19:10,560 takes a year to to get there and then 2144 01:19:13,990 --> 01:19:12,480 you have quite a bit of time before you 2145 01:19:15,750 --> 01:19:14,000 have to do your return you could 2146 01:19:19,510 --> 01:19:15,760 actually return for less than two 2147 01:19:20,390 --> 01:19:19,520 kilometers per second that's 2001 gp 2148 01:19:22,870 --> 01:19:20,400 two 2149 01:19:26,310 --> 01:19:22,880 this this other one track we've done uh 2150 01:19:29,030 --> 01:19:26,320 2013 bs45 is very convenient you could 2151 01:19:31,910 --> 01:19:29,040 do scout missions at several points 2152 01:19:34,229 --> 01:19:31,920 along this this track and still have 2153 01:19:37,669 --> 01:19:34,239 time in the outer years to do your arn 2154 01:19:41,910 --> 01:19:37,679 mission again at a fairly low 2155 01:19:44,310 --> 01:19:42,790 so 2156 01:19:46,070 --> 01:19:44,320 we think that if you 2157 01:19:48,310 --> 01:19:46,080 design this program so it serves both 2158 01:19:50,470 --> 01:19:48,320 nasa and commercial needs nasa will get 2159 01:19:52,149 --> 01:19:50,480 the propellant and materials in orbit 2160 01:19:54,229 --> 01:19:52,159 that it needs to make getting to mars 2161 01:19:56,630 --> 01:19:54,239 less expensive industry gets what it 2162 01:19:59,189 --> 01:19:56,640 needs for its grandiose plans 2163 01:20:01,270 --> 01:19:59,199 and everyone benefits it's synergistic 2164 01:20:03,750 --> 01:20:01,280 and in the short term what we need to do 2165 01:20:05,830 --> 01:20:03,760 is commission several precursors to do 2166 01:20:07,910 --> 01:20:05,840 rendezvous and sample return missions 2167 01:20:09,350 --> 01:20:07,920 previous speakers have have 2168 01:20:11,669 --> 01:20:09,360 described 2169 01:20:14,390 --> 01:20:11,679 ar arvs 2170 01:20:15,990 --> 01:20:14,400 loaded with instruments just to find out 2171 01:20:18,950 --> 01:20:16,000 what the mass of the target that they're 2172 01:20:20,790 --> 01:20:18,960 already committed to getting would be 2173 01:20:22,390 --> 01:20:20,800 you need that information 2174 01:20:24,550 --> 01:20:22,400 before you launch 2175 01:20:26,070 --> 01:20:24,560 before you've committed to that target 2176 01:20:27,430 --> 01:20:26,080 the other thing we think we need in the 2177 01:20:29,430 --> 01:20:27,440 short term as a 2178 01:20:31,669 --> 01:20:29,440 baa for 2179 01:20:33,750 --> 01:20:31,679 asteroid recovery mission ideas 2180 01:20:35,030 --> 01:20:33,760 on on how to gather mission material 2181 01:20:37,430 --> 01:20:35,040 from any size 2182 01:20:40,390 --> 01:20:37,440 nea and and how to structure it so it 2183 01:20:41,669 --> 01:20:40,400 works on an industry based approach 2184 01:20:44,470 --> 01:20:41,679 and 2185 01:20:47,270 --> 01:20:44,480 finally with arv size unhitched from 2186 01:20:49,350 --> 01:20:47,280 from asteroid size 2187 01:20:50,870 --> 01:20:49,360 we should be optimizing for for the 2188 01:20:53,669 --> 01:20:50,880 least cost 2189 01:20:55,110 --> 01:20:53,679 it's it's very grand to set a really big 2190 01:20:57,350 --> 01:20:55,120 technical goal 2191 01:21:00,550 --> 01:20:57,360 like a you know a gigawatt of onboard 2192 01:21:01,910 --> 01:21:00,560 power for your iron propulsion 2193 01:21:04,070 --> 01:21:01,920 but if that turns out to cost you a 2194 01:21:06,229 --> 01:21:04,080 billion dollars a mission 2195 01:21:08,310 --> 01:21:06,239 you might do it once but you'll never do 2196 01:21:10,070 --> 01:21:08,320 it again 2197 01:21:12,470 --> 01:21:10,080 in the future where all of us will have 2198 01:21:14,310 --> 01:21:12,480 to be much more sensitive to designing 2199 01:21:15,590 --> 01:21:14,320 least cost combinations that can be 2200 01:21:17,110 --> 01:21:15,600 sustained 2201 01:21:18,870 --> 01:21:17,120 versus 2202 01:21:19,910 --> 01:21:18,880 setting a technical goal that's really 2203 01:21:21,910 --> 01:21:19,920 ambitious 2204 01:21:23,510 --> 01:21:21,920 and hoping that in the fullness of time 2205 01:21:24,709 --> 01:21:23,520 that results in a capability that can be 2206 01:21:34,310 --> 01:21:24,719 used again 2207 01:21:39,510 --> 01:21:37,110 okay do we have a question 2208 01:21:42,070 --> 01:21:39,520 is is there a business model for 2209 01:21:43,910 --> 01:21:42,080 paying you by the kilogram 2210 01:21:46,470 --> 01:21:43,920 yes for return of sample 2211 01:21:48,149 --> 01:21:46,480 yes that on a per kilogram basis you 2212 01:21:49,590 --> 01:21:48,159 know will be a lot cheaper than 2213 01:21:51,030 --> 01:21:49,600 osiris-rex 2214 01:21:51,830 --> 01:21:51,040 um 2215 01:21:53,830 --> 01:21:51,840 and 2216 01:21:56,470 --> 01:21:53,840 it's valuable to both parties we'll 2217 01:21:57,910 --> 01:21:56,480 we'll need samples for our own needs we 2218 01:21:59,669 --> 01:21:57,920 we want to supply propellant to 2219 01:22:01,830 --> 01:21:59,679 communication satellites to transfer 2220 01:22:03,669 --> 01:22:01,840 stages you know a lot of the the new 2221 01:22:06,070 --> 01:22:03,679 launch vehicles that rely on on air 2222 01:22:07,350 --> 01:22:06,080 launch they have a ceiling on how much 2223 01:22:11,430 --> 01:22:07,360 they can launch 2224 01:22:12,870 --> 01:22:11,440 just to leo and use a transfer stage 2225 01:22:15,350 --> 01:22:12,880 that's space-based 2226 01:22:16,709 --> 01:22:15,360 refueled from asteroid resources 2227 01:22:18,790 --> 01:22:16,719 they gain a whole other order of 2228 01:22:21,030 --> 01:22:18,800 magnitude capabilities so we think 2229 01:22:27,990 --> 01:22:21,040 there's a lot of commercial demand for 2230 01:22:28,000 --> 01:22:31,270 anything other questions 2231 01:22:31,280 --> 01:22:36,390 thanks 2232 01:22:42,950 --> 01:22:40,950 okay um our last presenter um in the 2233 01:22:45,750 --> 01:22:42,960 formal agenda 2234 01:22:48,470 --> 01:22:45,760 is a combination presentation by bill 2235 01:22:50,310 --> 01:22:48,480 botkey from southwest research and and 2236 01:22:52,390 --> 01:22:50,320 robert jedecki 2237 01:22:53,590 --> 01:22:52,400 from university of hawaii 2238 01:22:55,990 --> 01:22:53,600 um 2239 01:22:58,550 --> 01:22:56,000 dr botkey is director of the center for 2240 01:23:00,790 --> 01:22:58,560 lunar origin and evolution of nasa's 2241 01:23:02,229 --> 01:23:00,800 lunar science institute and director of 2242 01:23:04,310 --> 01:23:02,239 the department of space studies at 2243 01:23:06,709 --> 01:23:04,320 southwest research institute in boulder 2244 01:23:09,430 --> 01:23:06,719 also a flood survivor 2245 01:23:11,189 --> 01:23:09,440 and professor uh robert jedikis of the 2246 01:23:13,750 --> 01:23:11,199 university of hawaii and the asteroid 2247 01:23:15,270 --> 01:23:13,760 terrestrial impact last alert system or 2248 01:23:16,870 --> 01:23:15,280 atlas 2249 01:23:18,790 --> 01:23:16,880 the population of asteroids that are 2250 01:23:21,189 --> 01:23:18,800 temporarily captured in orbit around 2251 01:23:22,629 --> 01:23:21,199 this earth what bill and robert call 2252 01:23:25,189 --> 01:23:22,639 many moons 2253 01:23:27,510 --> 01:23:25,199 are new and highly compelling targets 2254 01:23:29,189 --> 01:23:27,520 for human exploration because of their 2255 01:23:31,270 --> 01:23:29,199 proximity to earth and their low 2256 01:23:32,950 --> 01:23:31,280 geocentric velocities 2257 01:23:34,709 --> 01:23:32,960 they believe this population can help 2258 01:23:36,870 --> 01:23:34,719 nasa address perhaps 2259 01:23:38,950 --> 01:23:36,880 exploration's most problematic issue 2260 01:23:40,950 --> 01:23:38,960 that is identifying a near-earth 2261 01:23:42,629 --> 01:23:40,960 asteroid population that asteroids 2262 01:23:44,310 --> 01:23:42,639 astronauts and their tools can interact 2263 01:23:45,510 --> 01:23:44,320 with within cost and scheduling 2264 01:23:47,270 --> 01:23:45,520 constraints 2265 01:23:50,070 --> 01:23:47,280 and here they'll briefly discuss what 2266 01:23:52,149 --> 01:23:50,080 many moons are what their orbits sizes 2267 01:23:53,750 --> 01:23:52,159 and physical properties may be like what 2268 01:23:55,510 --> 01:23:53,760 can be done to find them and how human 2269 01:23:57,189 --> 01:23:55,520 and robotic spacecraft can potentially 2270 01:23:59,830 --> 01:23:57,199 interact with them and i will say they 2271 01:24:01,669 --> 01:23:59,840 both submitted separate rfi responses 2272 01:24:03,189 --> 01:24:01,679 but the topics were so complementary 2273 01:24:05,510 --> 01:24:03,199 we're having them present to and they 2274 01:24:06,550 --> 01:24:05,520 graciously agreed to present together so 2275 01:24:08,149 --> 01:24:06,560 go ahead 2276 01:24:09,590 --> 01:24:08,159 thank you very much oh well robert and i 2277 01:24:11,189 --> 01:24:09,600 work closely together so this is no 2278 01:24:12,070 --> 01:24:11,199 we're actually very happy to be talking 2279 01:24:13,750 --> 01:24:12,080 together 2280 01:24:15,510 --> 01:24:13,760 so this is very different from the other 2281 01:24:17,510 --> 01:24:15,520 talks i think you've seen this session 2282 01:24:19,189 --> 01:24:17,520 so far we've mostly talked about of the 2283 01:24:20,470 --> 01:24:19,199 arm mission we're going to propose a 2284 01:24:21,910 --> 01:24:20,480 different mission no one asked us they 2285 01:24:23,590 --> 01:24:21,920 should have asked us beforehand but we 2286 01:24:25,189 --> 01:24:23,600 think we have a 2287 01:24:27,830 --> 01:24:25,199 mission concept 2288 01:24:30,070 --> 01:24:27,840 for a human mission which we're calling 2289 01:24:31,510 --> 01:24:30,080 uh admission to a mini moon and what 2290 01:24:32,870 --> 01:24:31,520 we're excited about this is maybe one of 2291 01:24:35,430 --> 01:24:32,880 the most exciting ideas i think i've 2292 01:24:38,310 --> 01:24:35,440 seen in my career in a sense that this 2293 01:24:40,550 --> 01:24:38,320 has the promise to help achieve nasa's 2294 01:24:42,950 --> 01:24:40,560 human spaceflight goals but at lower 2295 01:24:44,390 --> 01:24:42,960 costs and reduce risk than the things 2296 01:24:45,990 --> 01:24:44,400 that are being presented today 2297 01:24:47,350 --> 01:24:46,000 so to give you a feeling for this i have 2298 01:24:48,790 --> 01:24:47,360 to describe many moods that means i have 2299 01:24:50,629 --> 01:24:48,800 to give you something of a background on 2300 01:24:52,709 --> 01:24:50,639 the near earth object population so 2301 01:24:54,470 --> 01:24:52,719 first of all what are minimums 2302 01:24:55,910 --> 01:24:54,480 well let's start with sort of a top view 2303 01:24:58,070 --> 01:24:55,920 of the solar system so what you're 2304 01:24:59,430 --> 01:24:58,080 looking at here in green are is the main 2305 01:25:01,110 --> 01:24:59,440 asteroid belt and then you can see the 2306 01:25:02,470 --> 01:25:01,120 orbits of the terrestrial planets and 2307 01:25:04,629 --> 01:25:02,480 jupiter out here 2308 01:25:06,470 --> 01:25:04,639 now the asteroid belt provides the 2309 01:25:08,070 --> 01:25:06,480 source for our nearest object population 2310 01:25:09,669 --> 01:25:08,080 through different dynamical processes in 2311 01:25:11,510 --> 01:25:09,679 the rest the near-earth objects are the 2312 01:25:13,590 --> 01:25:11,520 objects here in red these are bodies 2313 01:25:14,950 --> 01:25:13,600 across the earth's path or in some cases 2314 01:25:16,629 --> 01:25:14,960 come very close to the earth and they're 2315 01:25:18,709 --> 01:25:16,639 what we're talking about today 2316 01:25:20,550 --> 01:25:18,719 now the armed mission candidates are a 2317 01:25:22,629 --> 01:25:20,560 subset of that population they just 2318 01:25:24,470 --> 01:25:22,639 happen to be the objects they're on very 2319 01:25:26,390 --> 01:25:24,480 low eccentricity very low inclination 2320 01:25:28,229 --> 01:25:26,400 orbits so they're really much smaller 2321 01:25:29,430 --> 01:25:28,239 than this near earth object population 2322 01:25:31,430 --> 01:25:29,440 but what's interesting is while 2323 01:25:33,669 --> 01:25:31,440 everyone's focusing on these guys these 2324 01:25:35,350 --> 01:25:33,679 objects actually do some special things 2325 01:25:36,310 --> 01:25:35,360 if you look at them and you think about 2326 01:25:37,669 --> 01:25:36,320 something we're going to call the 2327 01:25:39,270 --> 01:25:37,679 lagrange points i'm not going to spend a 2328 01:25:41,189 --> 01:25:39,280 lot of time going in the dynamics of 2329 01:25:43,910 --> 01:25:41,199 lagrange points but essentially when you 2330 01:25:45,990 --> 01:25:43,920 have objects on earth like orbits 2331 01:25:47,750 --> 01:25:46,000 they tend to spend a lot of time in 2332 01:25:50,070 --> 01:25:47,760 special regions where the gravitational 2333 01:25:51,510 --> 01:25:50,080 forces of the sun and the earth are very 2334 01:25:52,870 --> 01:25:51,520 comparable to one another and so when 2335 01:25:54,790 --> 01:25:52,880 you combine with the orbital motion it 2336 01:25:57,030 --> 01:25:54,800 actually creates a pathway where things 2337 01:25:58,870 --> 01:25:57,040 can go in from orbiting the sun to 2338 01:26:01,510 --> 01:25:58,880 actually going into orbit around the 2339 01:26:02,709 --> 01:26:01,520 earth itself okay so this pathway is 2340 01:26:05,110 --> 01:26:02,719 very interesting for the following 2341 01:26:07,669 --> 01:26:05,120 reason and that some asteroids actually 2342 01:26:09,189 --> 01:26:07,679 enter into a lagrange point like l1 they 2343 01:26:10,550 --> 01:26:09,199 rattle around the earth moon system for 2344 01:26:13,030 --> 01:26:10,560 a time and then eventually they may 2345 01:26:15,110 --> 01:26:13,040 escape out l2 or so so these are 2346 01:26:16,950 --> 01:26:15,120 temporarily captured asteroids but the 2347 01:26:18,550 --> 01:26:16,960 ones that we make a full orbit around 2348 01:26:20,870 --> 01:26:18,560 the earth we call mini boots okay that's 2349 01:26:22,310 --> 01:26:20,880 our that's our formal name for it okay 2350 01:26:24,070 --> 01:26:22,320 but what's interesting here is that some 2351 01:26:26,149 --> 01:26:24,080 objects are very are only temporarily 2352 01:26:28,149 --> 01:26:26,159 kept over a short time scale but others 2353 01:26:30,470 --> 01:26:28,159 are more are captured over a much longer 2354 01:26:31,990 --> 01:26:30,480 time scale some cases up to years even 2355 01:26:33,910 --> 01:26:32,000 decades depending on how you look at it 2356 01:26:35,750 --> 01:26:33,920 or so so this makes them very 2357 01:26:37,430 --> 01:26:35,760 interesting targets for something we 2358 01:26:38,229 --> 01:26:37,440 might want to visit in the near future 2359 01:26:40,310 --> 01:26:38,239 okay 2360 01:26:41,910 --> 01:26:40,320 so if this just gives you a feeling for 2361 01:26:43,510 --> 01:26:41,920 me also for the people on webex it's the 2362 01:26:45,270 --> 01:26:43,520 feeling for some of the trajectories of 2363 01:26:46,790 --> 01:26:45,280 these objects some are very simple they 2364 01:26:49,430 --> 01:26:46,800 just make one sort of orbit around the 2365 01:26:50,709 --> 01:26:49,440 earth some may make multiple passes and 2366 01:26:52,229 --> 01:26:50,719 then all of a sudden you can get crazy 2367 01:26:53,510 --> 01:26:52,239 trajectories as these things interact 2368 01:26:54,950 --> 01:26:53,520 with the moon and they interact with 2369 01:26:55,910 --> 01:26:54,960 resonances with the earth and the rest 2370 01:26:57,750 --> 01:26:55,920 you know that's where i have a whole 2371 01:27:00,550 --> 01:26:57,760 rogues gallery of things basically the 2372 01:27:01,830 --> 01:27:00,560 entire sphere of out to about four lunar 2373 01:27:03,430 --> 01:27:01,840 distances can be filled with these 2374 01:27:04,790 --> 01:27:03,440 objects 2375 01:27:06,470 --> 01:27:04,800 so the question is how many of these 2376 01:27:08,470 --> 01:27:06,480 guys exist okay that might be some of 2377 01:27:10,149 --> 01:27:08,480 the questions you want to know to answer 2378 01:27:11,830 --> 01:27:10,159 that we had to do some dynamical studies 2379 01:27:13,750 --> 01:27:11,840 this is some work done by mikhail 2380 01:27:15,669 --> 01:27:13,760 granvik and robert jediki just over the 2381 01:27:17,750 --> 01:27:15,679 last sort of recent history what they 2382 01:27:19,669 --> 01:27:17,760 did is they looked at the orbits of 2383 01:27:21,510 --> 01:27:19,679 essentially the arm candidates and this 2384 01:27:23,110 --> 01:27:21,520 is of the plot in some major axis and 2385 01:27:24,950 --> 01:27:23,120 eccentricity and then numerical 2386 01:27:27,430 --> 01:27:24,960 calculations to see how many objects 2387 01:27:28,709 --> 01:27:27,440 would be captured over time and just 2388 01:27:29,830 --> 01:27:28,719 give you the bottom line here's a lot i 2389 01:27:31,590 --> 01:27:29,840 could say in this plot but i don't have 2390 01:27:33,430 --> 01:27:31,600 time it's basically on the order of ten 2391 01:27:35,430 --> 01:27:33,440 the minus four to ten minus fifth of the 2392 01:27:36,790 --> 01:27:35,440 population is captured at any given time 2393 01:27:39,910 --> 01:27:36,800 or for those like think of percentages 2394 01:27:41,189 --> 01:27:39,920 it's about 0.001 so it's not very large 2395 01:27:43,510 --> 01:27:41,199 so what does that mean in terms of the 2396 01:27:44,870 --> 01:27:43,520 entire population well let's go back to 2397 01:27:46,870 --> 01:27:44,880 let's think back to the plot i just 2398 01:27:48,310 --> 01:27:46,880 showed you in white i'm showing a plot 2399 01:27:50,149 --> 01:27:48,320 of diameter and kilometers versus 2400 01:27:51,910 --> 01:27:50,159 cumulative number and right here we have 2401 01:27:54,070 --> 01:27:51,920 what we think the main main belt 2402 01:27:55,430 --> 01:27:54,080 asteroid population is like and yellow 2403 01:27:56,950 --> 01:27:55,440 is our best estimate of the near earth 2404 01:27:58,950 --> 01:27:56,960 object population remember that's just a 2405 01:28:01,590 --> 01:27:58,960 sort of a in a sense it's a dynamically 2406 01:28:03,270 --> 01:28:01,600 escaped subset of the main belt from 2407 01:28:05,030 --> 01:28:03,280 there we have the population of arm 2408 01:28:06,870 --> 01:28:05,040 candidates that's just a subset of the 2409 01:28:08,229 --> 01:28:06,880 near earth object population so if we 2410 01:28:10,310 --> 01:28:08,239 take that best estimate we have for the 2411 01:28:12,310 --> 01:28:10,320 armed population and we multiply it by 2412 01:28:14,070 --> 01:28:12,320 about 10 to the minus fifth or so we end 2413 01:28:15,750 --> 01:28:14,080 up with a population of model minions 2414 01:28:17,430 --> 01:28:15,760 okay so these are objects there's not a 2415 01:28:19,030 --> 01:28:17,440 lot of these guys but they're in steady 2416 01:28:21,189 --> 01:28:19,040 state so at any given time there's 2417 01:28:23,110 --> 01:28:21,199 several meter-sized guys to visit in the 2418 01:28:24,629 --> 01:28:23,120 earth moon system so what does that mean 2419 01:28:25,910 --> 01:28:24,639 what's the bottom line on that so 2420 01:28:27,750 --> 01:28:25,920 essentially what we're talking about is 2421 01:28:30,390 --> 01:28:27,760 a few objects which are maybe on the 2422 01:28:31,990 --> 01:28:30,400 order of a washing machine or so okay we 2423 01:28:33,669 --> 01:28:32,000 maybe have a dozen objects or so which 2424 01:28:35,110 --> 01:28:33,679 are maybe about the size of a beach ball 2425 01:28:37,110 --> 01:28:35,120 and then every once in a while we have a 2426 01:28:39,189 --> 01:28:37,120 larger object okay so they're not very 2427 01:28:41,669 --> 01:28:39,199 big but there's always something to go 2428 01:28:42,709 --> 01:28:41,679 visit okay and ultimately we're pretty 2429 01:28:43,830 --> 01:28:42,719 we're reasonably happy with these 2430 01:28:45,350 --> 01:28:43,840 numbers but we like to do more 2431 01:28:47,110 --> 01:28:45,360 observational work and robert's going to 2432 01:28:49,189 --> 01:28:47,120 talk about that and a better theoretical 2433 01:28:50,629 --> 01:28:49,199 study to understand this but even so 2434 01:28:52,149 --> 01:28:50,639 these objects are very interesting from 2435 01:28:54,229 --> 01:28:52,159 a science perspective 2436 01:28:55,910 --> 01:28:54,239 say okay so how long do they last 2437 01:28:57,990 --> 01:28:55,920 typically our numerical simulations 2438 01:28:59,189 --> 01:28:58,000 suggest they last on the order of about 2439 01:29:01,430 --> 01:28:59,199 three orbits around the earth moon 2440 01:29:02,390 --> 01:29:01,440 system or about 10 months and you can 2441 01:29:03,830 --> 01:29:02,400 see here there's something of a 2442 01:29:05,669 --> 01:29:03,840 long-lived tail where they can last much 2443 01:29:06,950 --> 01:29:05,679 longer or so so that's pretty short to 2444 01:29:08,629 --> 01:29:06,960 think about a human mission to these 2445 01:29:10,149 --> 01:29:08,639 things but keep in mind if you had a 2446 01:29:12,229 --> 01:29:10,159 robotic precursor go out to these 2447 01:29:13,910 --> 01:29:12,239 objects you could very easily stabilize 2448 01:29:15,350 --> 01:29:13,920 them it doesn't take much of a velocity 2449 01:29:17,189 --> 01:29:15,360 kick to actually put them into an orbit 2450 01:29:18,310 --> 01:29:17,199 which will last a hundred years or so so 2451 01:29:19,830 --> 01:29:18,320 in a sense you can think about them 2452 01:29:21,669 --> 01:29:19,840 almost as a mini arm being able to do 2453 01:29:23,510 --> 01:29:21,679 lots of interesting things here 2454 01:29:25,110 --> 01:29:23,520 okay so i want to close my portion of 2455 01:29:26,790 --> 01:29:25,120 talk just by saying why these things are 2456 01:29:28,310 --> 01:29:26,800 scientifically interesting why we might 2457 01:29:29,590 --> 01:29:28,320 want to go see these guys 2458 01:29:31,189 --> 01:29:29,600 so the first of all to understand is 2459 01:29:32,790 --> 01:29:31,199 that these objects are essentially the 2460 01:29:34,550 --> 01:29:32,800 precursors or the meteoroids that are 2461 01:29:36,070 --> 01:29:34,560 delivering meteorites to the earth and 2462 01:29:37,430 --> 01:29:36,080 so you have a sense you get you can get 2463 01:29:38,870 --> 01:29:37,440 samples that are outside the atmosphere 2464 01:29:40,390 --> 01:29:38,880 before any contamination or anything 2465 01:29:41,669 --> 01:29:40,400 else has taken place and they can 2466 01:29:43,350 --> 01:29:41,679 actually tell us about the original 2467 01:29:45,510 --> 01:29:43,360 building blocks which made the planets 2468 01:29:47,189 --> 01:29:45,520 and they also provide information on 2469 01:29:48,629 --> 01:29:47,199 possibly how life got going depending if 2470 01:29:50,470 --> 01:29:48,639 you get organics and volatiles and all 2471 01:29:52,149 --> 01:29:50,480 the rest this is a major nasa goal 2472 01:29:53,910 --> 01:29:52,159 that's demonstrated by the osiris-rex 2473 01:29:55,590 --> 01:29:53,920 mission that's out there there's also 2474 01:29:57,510 --> 01:29:55,600 the fact that these samples can be very 2475 01:29:59,350 --> 01:29:57,520 large and if you like it you can bring 2476 01:30:01,189 --> 01:29:59,360 the entire thing home depending on how 2477 01:30:02,390 --> 01:30:01,199 you want to do it and that's a key goal 2478 01:30:03,830 --> 01:30:02,400 regarding the study of asteroid 2479 01:30:04,709 --> 01:30:03,840 resources and we've already had talks on 2480 01:30:05,830 --> 01:30:04,719 that 2481 01:30:07,030 --> 01:30:05,840 finally there's something else to keep 2482 01:30:09,270 --> 01:30:07,040 in mind while everyone talks about 2483 01:30:11,110 --> 01:30:09,280 asteroids being rubble piles versus uh 2484 01:30:12,950 --> 01:30:11,120 solid objects there's one more issue to 2485 01:30:14,550 --> 01:30:12,960 keep in mind all of the asteroids we're 2486 01:30:16,229 --> 01:30:14,560 dealing with are small enough that 2487 01:30:17,590 --> 01:30:16,239 essentially they in some cases they may 2488 01:30:19,750 --> 01:30:17,600 literally be held together not by 2489 01:30:21,430 --> 01:30:19,760 necessarily gravity by electrostatic 2490 01:30:22,870 --> 01:30:21,440 cohesive forces this is becoming more 2491 01:30:24,390 --> 01:30:22,880 and more recognized in the small body 2492 01:30:26,550 --> 01:30:24,400 community so some of these objects may 2493 01:30:28,629 --> 01:30:26,560 literally be sand castles and if that's 2494 01:30:30,390 --> 01:30:28,639 true we really would be very important 2495 01:30:31,669 --> 01:30:30,400 to understand that nature before we send 2496 01:30:33,510 --> 01:30:31,679 humans out there to interact with them 2497 01:30:35,910 --> 01:30:33,520 in some fashion and so a mission to a 2498 01:30:36,950 --> 01:30:35,920 mini moon can buy down risk by 2499 01:30:38,550 --> 01:30:36,960 understanding these objects their 2500 01:30:40,629 --> 01:30:38,560 natural laboratories to understand these 2501 01:30:41,669 --> 01:30:40,639 really poorly understood processes and 2502 01:30:42,950 --> 01:30:41,679 so with that i'm going to hand it over 2503 01:30:54,390 --> 01:30:42,960 to robert and robert's going to tell you 2504 01:30:57,590 --> 01:30:56,070 thank you bill so i'm sure you're all 2505 01:30:59,189 --> 01:30:57,600 wondering uh just a couple theorists 2506 01:31:01,430 --> 01:30:59,199 standing up here talking about this 2507 01:31:02,870 --> 01:31:01,440 vapor these vapor moons up there going 2508 01:31:04,790 --> 01:31:02,880 around the earth can we actually find 2509 01:31:07,030 --> 01:31:04,800 them are they actually there 2510 01:31:09,110 --> 01:31:07,040 and uh the whole idea started up about 2511 01:31:11,189 --> 01:31:09,120 20 years ago when i was working in at 2512 01:31:12,629 --> 01:31:11,199 kid peak arizona i was working with a 2513 01:31:14,550 --> 01:31:12,639 project called the space watch project 2514 01:31:16,470 --> 01:31:14,560 looking for asteroids and every once in 2515 01:31:17,910 --> 01:31:16,480 a while we'd find a geocentric object 2516 01:31:20,229 --> 01:31:17,920 and it would have this very elliptical 2517 01:31:22,070 --> 01:31:20,239 high inclination high semi-major axis 2518 01:31:23,750 --> 01:31:22,080 orbit around the earth and i would 2519 01:31:24,790 --> 01:31:23,760 report it to the minor planet center and 2520 01:31:25,669 --> 01:31:24,800 they would write back to me saying oh 2521 01:31:27,430 --> 01:31:25,679 rob don't worry about it it's a 2522 01:31:28,870 --> 01:31:27,440 geocentric object i said what if it's a 2523 01:31:30,550 --> 01:31:28,880 natural geocentric object it's a very 2524 01:31:31,990 --> 01:31:30,560 strange orbit they said ah there are no 2525 01:31:33,189 --> 01:31:32,000 natural geocentric objects other than 2526 01:31:34,709 --> 01:31:33,199 the moon 2527 01:31:36,550 --> 01:31:34,719 they said they're all artificial and i 2528 01:31:37,430 --> 01:31:36,560 thought that was very odd so 20 years go 2529 01:31:39,510 --> 01:31:37,440 by 2530 01:31:40,950 --> 01:31:39,520 and a couple years ago i found this 2531 01:31:42,070 --> 01:31:40,960 postdoc who was willing to work with me 2532 01:31:43,270 --> 01:31:42,080 on this project and we did the 2533 01:31:44,950 --> 01:31:43,280 simulations and actually figured out 2534 01:31:46,870 --> 01:31:44,960 that yeah a very small fraction of the 2535 01:31:48,070 --> 01:31:46,880 population can go into orbit around the 2536 01:31:50,390 --> 01:31:48,080 earth 2537 01:31:51,910 --> 01:31:50,400 and they uh they can be captured by the 2538 01:31:53,750 --> 01:31:51,920 earth immune system unfortunately we 2539 01:31:56,149 --> 01:31:53,760 published our paper a few years after 2540 01:31:58,870 --> 01:31:56,159 the discovery of the first mini moon 2541 01:32:00,390 --> 01:31:58,880 2006 rh120 if only we had done this 10 2542 01:32:02,229 --> 01:32:00,400 years earlier we would have predicted 2543 01:32:03,830 --> 01:32:02,239 this object and the great thing about 2544 01:32:05,590 --> 01:32:03,840 this object is it's really a poster 2545 01:32:06,550 --> 01:32:05,600 child for many moons 2546 01:32:12,629 --> 01:32:06,560 it's 2547 01:32:15,189 --> 01:32:12,639 geocentric orbit we're all exactly what 2548 01:32:16,470 --> 01:32:15,199 we predicted on our model the duration 2549 01:32:18,629 --> 01:32:16,480 of time that it spent in orbit around 2550 01:32:20,550 --> 01:32:18,639 the earth was the average of what we 2551 01:32:22,070 --> 01:32:20,560 predicted minimum should spend around 2552 01:32:23,590 --> 01:32:22,080 the earth 2553 01:32:25,510 --> 01:32:23,600 basically everything it did was was 2554 01:32:27,030 --> 01:32:25,520 right even its size at 3 meters which is 2555 01:32:27,750 --> 01:32:27,040 about the you know height of a typical 2556 01:32:30,390 --> 01:32:27,760 uh 2557 01:32:32,470 --> 01:32:30,400 high diving board at a city pool right 2558 01:32:33,750 --> 01:32:32,480 even its size is about the right order 2559 01:32:35,830 --> 01:32:33,760 of magnitude that we expect from our 2560 01:32:37,990 --> 01:32:35,840 modeling one object like this goes into 2561 01:32:39,510 --> 01:32:38,000 orbit around the earth every 10 years 2562 01:32:41,350 --> 01:32:39,520 the surveys have been operating for 10 2563 01:32:43,270 --> 01:32:41,360 or 20 years at different uh levels of 2564 01:32:44,550 --> 01:32:43,280 efficiency so it's about the right order 2565 01:32:46,229 --> 01:32:44,560 magnitude for us to be finding these 2566 01:32:47,270 --> 01:32:46,239 objects so it was the poster child for 2567 01:32:49,110 --> 01:32:47,280 minimum 2568 01:32:51,669 --> 01:32:49,120 it was found at the time because it was 2569 01:32:53,510 --> 01:32:51,679 bright and very slow moving 2570 01:32:55,430 --> 01:32:53,520 and so it was it was relatively easy to 2571 01:32:56,950 --> 01:32:55,440 find by the catalina sky survey but this 2572 01:32:58,229 --> 01:32:56,960 is just we think this is just the tip of 2573 01:32:59,590 --> 01:32:58,239 the whole meaning and iceberg we think 2574 01:33:03,030 --> 01:32:59,600 there are many more out there and we 2575 01:33:07,110 --> 01:33:04,950 we've done a lot of simulations using 2576 01:33:08,470 --> 01:33:07,120 different assets on the ground if you're 2577 01:33:10,550 --> 01:33:08,480 on the ground you want to probably be 2578 01:33:13,030 --> 01:33:10,560 using visible light you would really 2579 01:33:15,030 --> 01:33:13,040 like a survey that's got a wide field 2580 01:33:17,030 --> 01:33:15,040 telescope that can get you extremely 2581 01:33:19,030 --> 01:33:17,040 faint limiting magnitudes that can take 2582 01:33:20,950 --> 01:33:19,040 very short exposures so something like 2583 01:33:22,229 --> 01:33:20,960 the large synoptic survey telescope that 2584 01:33:23,669 --> 01:33:22,239 should be operational about five or ten 2585 01:33:25,510 --> 01:33:23,679 years would be a really premier 2586 01:33:27,430 --> 01:33:25,520 instrument for finding these mini moons 2587 01:33:29,030 --> 01:33:27,440 but that's still you know a decade or so 2588 01:33:30,950 --> 01:33:29,040 in the future right now there is an 2589 01:33:32,629 --> 01:33:30,960 asset available the subaru telescope 2590 01:33:35,110 --> 01:33:32,639 eight meter telescope on the summit of 2591 01:33:37,750 --> 01:33:35,120 mauna kea hawaii and they're just 2592 01:33:38,709 --> 01:33:37,760 installing the hyper super prime cam 2593 01:33:40,790 --> 01:33:38,719 camera 2594 01:33:43,750 --> 01:33:40,800 and uh this is a phenomenal uh 2595 01:33:45,030 --> 01:33:43,760 instrument and we think that if we had 2596 01:33:47,110 --> 01:33:45,040 time on this telescope we would be able 2597 01:33:49,270 --> 01:33:47,120 to find mini moons in a regular way uh 2598 01:33:50,790 --> 01:33:49,280 we think that there's a 40 probability 2599 01:33:52,790 --> 01:33:50,800 of finding a mini moon on any night we 2600 01:33:54,550 --> 01:33:52,800 go observing with that telescope 2601 01:33:56,629 --> 01:33:54,560 which means that there's about a 90 2602 01:33:58,629 --> 01:33:56,639 percent chance of finding a mini moon if 2603 01:34:01,830 --> 01:33:58,639 we had five ninths in the telescope the 2604 01:34:03,750 --> 01:34:01,840 one missing key is that i would require 2605 01:34:04,870 --> 01:34:03,760 a wideband filter to optimize that's 2606 01:34:06,310 --> 01:34:04,880 optimized for the detection these 2607 01:34:08,229 --> 01:34:06,320 minimums right now they use relatively 2608 01:34:10,870 --> 01:34:08,239 narrow band filters for doing astronomy 2609 01:34:12,629 --> 01:34:10,880 and astrophysics and for doing asteroids 2610 01:34:14,149 --> 01:34:12,639 science you want or discovery you want 2611 01:34:16,149 --> 01:34:14,159 it very wide you want to basically learn 2612 01:34:17,590 --> 01:34:16,159 as much light as you possibly can but if 2613 01:34:19,590 --> 01:34:17,600 you really want to find a lot of minions 2614 01:34:21,669 --> 01:34:19,600 uh you know dozens at a time you want to 2615 01:34:23,510 --> 01:34:21,679 go to space so we've done simulations 2616 01:34:24,790 --> 01:34:23,520 from space and we think that if you're 2617 01:34:27,030 --> 01:34:24,800 going to go to space the best place to 2618 01:34:28,870 --> 01:34:27,040 be would be at l1 l1 is a location about 2619 01:34:30,470 --> 01:34:28,880 four lunar distances away from the earth 2620 01:34:32,790 --> 01:34:30,480 it's in the direction of sun so you're 2621 01:34:34,390 --> 01:34:32,800 looking sort of back towards the earth 2622 01:34:35,590 --> 01:34:34,400 and you're going to see the mini means 2623 01:34:38,310 --> 01:34:35,600 sort of distributed around the earth as 2624 01:34:41,030 --> 01:34:38,320 shown in this figure here 2625 01:34:44,070 --> 01:34:41,040 if you put a 1 meter diameter mirror 2626 01:34:45,830 --> 01:34:44,080 with an infrared camera at l1 we think 2627 01:34:48,149 --> 01:34:45,840 that there will be 30 detectable mini 2628 01:34:49,910 --> 01:34:48,159 moons on the sky plane at any time so 2629 01:34:51,510 --> 01:34:49,920 that you'd have dozens of mini moons 2630 01:34:52,550 --> 01:34:51,520 that were available you could you're not 2631 01:34:54,390 --> 01:34:52,560 they're not you know they're going to 2632 01:34:56,149 --> 01:34:54,400 come in and out of visibility so that 2633 01:34:57,510 --> 01:34:56,159 over the course of a month or six months 2634 01:34:59,109 --> 01:34:57,520 or a year you're going to see many many 2635 01:35:01,030 --> 01:34:59,119 dozens of mini moons 2636 01:35:02,790 --> 01:35:01,040 and that's extremely interesting to us 2637 01:35:04,709 --> 01:35:02,800 it's also interesting to us because 1 in 2638 01:35:06,390 --> 01:35:04,719 100 mini moons actually become large 2639 01:35:07,750 --> 01:35:06,400 bolide meteors right so that you can 2640 01:35:09,109 --> 01:35:07,760 find these things before they strike the 2641 01:35:10,629 --> 01:35:09,119 earth 2642 01:35:12,790 --> 01:35:10,639 and then you get the side benefit of if 2643 01:35:15,350 --> 01:35:12,800 you have a spacecraft like this at l1 2644 01:35:17,189 --> 01:35:15,360 looking back at the earth it's really a 2645 01:35:18,870 --> 01:35:17,199 early asteroid impact warning system as 2646 01:35:20,149 --> 01:35:18,880 well just like you've got satellites up 2647 01:35:22,390 --> 01:35:20,159 on orbit around the earth looking for 2648 01:35:24,070 --> 01:35:22,400 hurricanes and tornadoes uh this would 2649 01:35:25,669 --> 01:35:24,080 be an early impact warning system for 2650 01:35:29,910 --> 01:35:25,679 asteroids so not only finding many moons 2651 01:35:32,790 --> 01:35:31,590 so if we find them can you actually 2652 01:35:34,310 --> 01:35:32,800 visit them 2653 01:35:36,229 --> 01:35:34,320 those orbits that we showed look kind of 2654 01:35:37,590 --> 01:35:36,239 like crazy straws right and so i worked 2655 01:35:39,510 --> 01:35:37,600 with a mathematician at the university 2656 01:35:41,189 --> 01:35:39,520 of hawaii who was quite excited about 2657 01:35:42,550 --> 01:35:41,199 doing calculations to see whether or not 2658 01:35:44,870 --> 01:35:42,560 you could actually devise orbits to 2659 01:35:46,950 --> 01:35:44,880 these crazy straw uh objects 2660 01:35:49,270 --> 01:35:46,960 and uh what we found actually 2661 01:35:50,149 --> 01:35:49,280 is that if you or what we first of all 2662 01:35:52,149 --> 01:35:50,159 started 2663 01:35:53,430 --> 01:35:52,159 simulating was it let's we thought well 2664 01:35:54,950 --> 01:35:53,440 these things are only over for 10 months 2665 01:35:56,149 --> 01:35:54,960 you can't possibly get emissions you 2666 01:35:57,669 --> 01:35:56,159 know up and running and send it out in 2667 01:35:59,750 --> 01:35:57,679 10 months so what we thought instead is 2668 01:36:01,030 --> 01:35:59,760 let's put a spacecraft in geosynchronous 2669 01:36:02,790 --> 01:36:01,040 orbit and just let it stay there and 2670 01:36:04,390 --> 01:36:02,800 just store it there in hibernation until 2671 01:36:05,990 --> 01:36:04,400 we find the mini moon once we find the 2672 01:36:07,990 --> 01:36:06,000 minimum so we got the spacecraft here in 2673 01:36:09,830 --> 01:36:08,000 geocentric orbit and once we find a mini 2674 01:36:10,870 --> 01:36:09,840 moon as it's coming into the earth moon 2675 01:36:12,229 --> 01:36:10,880 system 2676 01:36:14,229 --> 01:36:12,239 we sort of triggered the spacecraft and 2677 01:36:15,510 --> 01:36:14,239 we say okay now now we have the orbit 2678 01:36:17,189 --> 01:36:15,520 for this object we've bounced radar off 2679 01:36:19,109 --> 01:36:17,199 it we've got a great orbit we can 2680 01:36:21,109 --> 01:36:19,119 deorbit it from geosync and make it 2681 01:36:22,870 --> 01:36:21,119 rendezvous with the 2682 01:36:25,030 --> 01:36:22,880 asteroid we can match its speed and 2683 01:36:26,870 --> 01:36:25,040 velocity we found out that every single 2684 01:36:28,229 --> 01:36:26,880 one of the 17 000 mini moons that we 2685 01:36:29,510 --> 01:36:28,239 created in our simulations we could 2686 01:36:30,629 --> 01:36:29,520 actually get to with this kind of a 2687 01:36:34,870 --> 01:36:30,639 scenario 2688 01:36:36,229 --> 01:36:34,880 looking at storing the spacecraft at l1 2689 01:36:38,070 --> 01:36:36,239 or l2 to see whether or not there's any 2690 01:36:40,070 --> 01:36:38,080 difference we our preliminary work 2691 01:36:41,669 --> 01:36:40,080 suggests that it's possible to get to 2692 01:36:44,870 --> 01:36:41,679 the mini moons all the mini moons even 2693 01:36:46,310 --> 01:36:44,880 if you're store starting at l1 or l2 2694 01:36:47,910 --> 01:36:46,320 for human machine landing you'd probably 2695 01:36:49,189 --> 01:36:47,920 want a mini moon that was on a longer 2696 01:36:50,550 --> 01:36:49,199 term orbit you wouldn't want something 2697 01:36:51,430 --> 01:36:50,560 that's just there for 10 months you'd 2698 01:36:54,149 --> 01:36:51,440 probably want something that was going 2699 01:36:55,669 --> 01:36:54,159 to be there for years so you could take 2700 01:36:57,109 --> 01:36:55,679 you could you might get lucky you might 2701 01:36:58,950 --> 01:36:57,119 find one of these at these mini moons 2702 01:37:00,870 --> 01:36:58,960 that are in a long-term stable orbit or 2703 01:37:02,310 --> 01:37:00,880 you could do as bill suggested that you 2704 01:37:04,950 --> 01:37:02,320 could launch a precursor mission to go 2705 01:37:07,189 --> 01:37:04,960 and stabilize a minimum orbit to make it 2706 01:37:09,430 --> 01:37:07,199 stable for centuries or so 2707 01:37:12,149 --> 01:37:09,440 uh when at that kind of level you should 2708 01:37:13,510 --> 01:37:12,159 be able to have an orion a a mission 2709 01:37:15,990 --> 01:37:13,520 that you could do get to with orion 2710 01:37:18,390 --> 01:37:16,000 spacecraft um sort of in a two to three 2711 01:37:19,669 --> 01:37:18,400 week time frame so you know these mini 2712 01:37:21,030 --> 01:37:19,679 moons are at the sort of the distance of 2713 01:37:22,790 --> 01:37:21,040 the moon on average right so it's about 2714 01:37:24,229 --> 01:37:22,800 the same amount of time as it takes to 2715 01:37:25,910 --> 01:37:24,239 get to the moon and come back and have a 2716 01:37:27,270 --> 01:37:25,920 mission to the moon so you know we're 2717 01:37:29,510 --> 01:37:27,280 talking about very reasonable time 2718 01:37:30,870 --> 01:37:29,520 frames for manned missions to these mini 2719 01:37:34,310 --> 01:37:30,880 moons 2720 01:37:35,910 --> 01:37:34,320 of advantages they offer a great way to 2721 01:37:37,510 --> 01:37:35,920 test arm technologies i mean i've been 2722 01:37:39,109 --> 01:37:37,520 really impressed by all the great ideas 2723 01:37:40,870 --> 01:37:39,119 you guys have been talking about 2724 01:37:43,910 --> 01:37:40,880 and i think that all of them can be 2725 01:37:45,910 --> 01:37:43,920 applied easy more easily to the minimum 2726 01:37:47,109 --> 01:37:45,920 idea these things are right in our 2727 01:37:48,550 --> 01:37:47,119 backyard they're going around the earth 2728 01:37:50,070 --> 01:37:48,560 they're extremely low delta-v targets 2729 01:37:51,590 --> 01:37:50,080 they're smaller asteroids they're easier 2730 01:37:54,550 --> 01:37:51,600 to capture easier to bring back easier 2731 01:37:58,790 --> 01:37:56,229 and in scientifically it'd be extremely 2732 01:38:00,629 --> 01:37:58,800 interesting to bring back an entire 2733 01:38:02,070 --> 01:38:00,639 intact one-half meter or one meter 2734 01:38:03,830 --> 01:38:02,080 diameter asteroid bring it back to the 2735 01:38:05,270 --> 01:38:03,840 earth and uh the interesting thing is 2736 01:38:07,189 --> 01:38:05,280 the mini moons are detectable with our 2737 01:38:08,950 --> 01:38:07,199 existing assets we just need to apply 2738 01:38:10,790 --> 01:38:08,960 something like subaru telescope to 2739 01:38:12,229 --> 01:38:10,800 finding these objects or we could be a 2740 01:38:14,229 --> 01:38:12,239 little more ambitious develop an 2741 01:38:16,070 --> 01:38:14,239 asteroid impact warning system put it l1 2742 01:38:17,750 --> 01:38:16,080 that will also find the minimums for us 2743 01:38:19,910 --> 01:38:17,760 so at the very least we think many moons 2744 01:38:21,510 --> 01:38:19,920 warn an in-depth study to determine 2745 01:38:24,310 --> 01:38:21,520 whether or not they're useful for the 2746 01:38:31,350 --> 01:38:24,320 spacecraft industry 2747 01:38:36,310 --> 01:38:34,550 any questions for bill and robert 2748 01:38:39,189 --> 01:38:36,320 yeah you said of the 2749 01:38:41,669 --> 01:38:39,199 17 000 in your simulation that all of 2750 01:38:43,669 --> 01:38:41,679 them you could get to them 2751 01:38:48,310 --> 01:38:43,679 when leaving from geo what was your 2752 01:38:52,870 --> 01:38:50,390 it was a couple for a few kilometers per 2753 01:38:55,510 --> 01:38:52,880 second a few columns okay thanks 2754 01:38:56,470 --> 01:38:55,520 so geo is the wrong place to wait 2755 01:38:57,510 --> 01:38:56,480 yeah 2756 01:39:00,390 --> 01:38:57,520 um 2757 01:39:02,870 --> 01:39:00,400 we we know that now 2758 01:39:04,550 --> 01:39:02,880 you you might repeat that 2759 01:39:05,990 --> 01:39:04,560 yeah yeah we know that now we we've 2760 01:39:07,990 --> 01:39:06,000 since learned we're simulating what 2761 01:39:09,910 --> 01:39:08,000 would happen if uh wait from when we're 2762 01:39:11,669 --> 01:39:09,920 waiting at l1 or lt 2763 01:39:15,030 --> 01:39:11,679 and how much delta v does it take to 2764 01:39:17,750 --> 01:39:15,040 stabilize the the asteroid itself 2765 01:39:22,070 --> 01:39:17,760 do you know that answer that um 2766 01:39:26,070 --> 01:39:24,149 okay so the question was how much how 2767 01:39:27,910 --> 01:39:26,080 much delta v does it take to stabilize 2768 01:39:29,430 --> 01:39:27,920 these uh mini moons uh the question is 2769 01:39:30,470 --> 01:39:29,440 we don't know because we haven't had we 2770 01:39:32,390 --> 01:39:30,480 haven't gotten the funding yet to do 2771 01:39:34,629 --> 01:39:32,400 that study if they fund us we'll let you 2772 01:39:36,149 --> 01:39:34,639 know but but typically what you can 2773 01:39:37,590 --> 01:39:36,159 think about though is you think about 2774 01:39:38,790 --> 01:39:37,600 the difference between you know the many 2775 01:39:40,709 --> 01:39:38,800 more orbits we showed and then the 2776 01:39:42,149 --> 01:39:40,719 long-lived tail it doesn't take very 2777 01:39:43,750 --> 01:39:42,159 much velocity to put them onto a 2778 01:39:45,030 --> 01:39:43,760 long-term stable orbit so i would think 2779 01:39:47,109 --> 01:39:45,040 the velocity requirements are going to 2780 01:39:48,950 --> 01:39:47,119 be very very small so you could think 2781 01:39:50,629 --> 01:39:48,960 about even doing this in a 2782 01:39:52,229 --> 01:39:50,639 you know rather than putting some 2783 01:39:53,910 --> 01:39:52,239 mechanism on it you might even be able 2784 01:39:55,109 --> 01:39:53,920 to do this by a gravity tractor in some 2785 01:39:56,470 --> 01:39:55,119 sense in some cases we're talking about 2786 01:39:57,750 --> 01:39:56,480 small enough objects that that's very 2787 01:40:01,990 --> 01:39:57,760 viable to do so there's all sorts of 2788 01:40:05,189 --> 01:40:03,750 how many of these objects have i know 2789 01:40:06,830 --> 01:40:05,199 we're not haven't been looking for them 2790 01:40:10,229 --> 01:40:06,840 very much but how many have been 2791 01:40:13,590 --> 01:40:10,239 cataloged one in just one just just one 2792 01:40:15,189 --> 01:40:13,600 one object and uh and and and that even 2793 01:40:17,030 --> 01:40:15,199 that is very consistent with our models 2794 01:40:18,550 --> 01:40:17,040 with our simulation so we've taken our 2795 01:40:20,070 --> 01:40:18,560 mini moon model run it through 2796 01:40:21,830 --> 01:40:20,080 simulations of existing surveys to 2797 01:40:23,669 --> 01:40:21,840 predict how many would be found and the 2798 01:40:25,510 --> 01:40:23,679 answer is basically the one object that 2799 01:40:27,030 --> 01:40:25,520 was found because in order to find these 2800 01:40:29,189 --> 01:40:27,040 things you need to design a specific 2801 01:40:30,950 --> 01:40:29,199 strategy the asteroid surveys that are 2802 01:40:32,310 --> 01:40:30,960 in operation right now are not really 2803 01:40:34,149 --> 01:40:32,320 looking for these things in fact you 2804 01:40:36,310 --> 01:40:34,159 know we think probably a project like 2805 01:40:38,229 --> 01:40:36,320 pan stars that i used to work on has 2806 01:40:39,590 --> 01:40:38,239 probably detected these things but just 2807 01:40:41,109 --> 01:40:39,600 detecting something is different than 2808 01:40:42,149 --> 01:40:41,119 discovering and realizing it's a mini 2809 01:40:43,750 --> 01:40:42,159 moon because many moons have got 2810 01:40:44,950 --> 01:40:43,760 different sky motions and different 2811 01:40:46,950 --> 01:40:44,960 properties and they're different they're 2812 01:40:51,590 --> 01:40:46,960 more difficult to link than heliocentric 2813 01:40:55,990 --> 01:40:53,270 what about your what about your data 2814 01:40:57,189 --> 01:40:56,000 from 20 years ago 2815 01:40:58,870 --> 01:40:57,199 yeah i thought about going back and 2816 01:41:01,750 --> 01:40:58,880 looking that up 2817 01:41:03,669 --> 01:41:01,760 the thing is that with those objects we 2818 01:41:05,430 --> 01:41:03,679 we only had what would happen typically 2819 01:41:06,950 --> 01:41:05,440 is i would we would track them for a few 2820 01:41:08,310 --> 01:41:06,960 hours on one night 2821 01:41:09,590 --> 01:41:08,320 and then we'd send them into the minor 2822 01:41:11,270 --> 01:41:09,600 planet center they'd say don't worry 2823 01:41:12,550 --> 01:41:11,280 about it and then we'd stop it we 2824 01:41:19,030 --> 01:41:12,560 wouldn't bother looking at for the next 2825 01:41:23,189 --> 01:41:20,470 there was perhaps another aspect to 2826 01:41:25,830 --> 01:41:23,199 consider is that uh uh near earth object 2827 01:41:28,310 --> 01:41:25,840 surveys are strongly discouraged from 2828 01:41:30,709 --> 01:41:28,320 tracking geocentric uh objects for 2829 01:41:33,750 --> 01:41:30,719 reasons that have to do with 2830 01:41:36,870 --> 01:41:33,760 uh space space surveillance issues 2831 01:41:38,470 --> 01:41:36,880 so so uh only recently has become 2832 01:41:39,830 --> 01:41:38,480 people have become aware that maybe they 2833 01:41:42,070 --> 01:41:39,840 should 2834 01:41:44,550 --> 01:41:42,080 consider other possibilities 2835 01:41:47,590 --> 01:41:44,560 there's also another possible detection 2836 01:41:48,709 --> 01:41:47,600 of mini moons at roughly the same time 2837 01:41:50,629 --> 01:41:48,719 that we were finding these things at 2838 01:41:53,510 --> 01:41:50,639 spacewatch 20 years ago the air force 2839 01:41:54,629 --> 01:41:53,520 did a radar survey looking for objects 2840 01:41:56,310 --> 01:41:54,639 and they found 2841 01:41:58,709 --> 01:41:56,320 it's recently been declassified and they 2842 01:42:00,709 --> 01:41:58,719 found three objects that were on 2843 01:42:02,310 --> 01:42:00,719 extremely unusual orbits that they that 2844 01:42:04,950 --> 01:42:02,320 they they did not think were consistent 2845 01:42:06,470 --> 01:42:04,960 with any artificial known uh satellites 2846 01:42:07,750 --> 01:42:06,480 or even debris from any satellites 2847 01:42:09,830 --> 01:42:07,760 because the orbits were so strange 2848 01:42:12,149 --> 01:42:09,840 however those orbits are extremely like 2849 01:42:13,830 --> 01:42:12,159 mini moon orbits and at the time they 2850 01:42:15,270 --> 01:42:13,840 speculated whether or not they could be 2851 01:42:17,030 --> 01:42:15,280 natural objects but nothing was done 2852 01:42:19,189 --> 01:42:17,040 about it 2853 01:42:24,310 --> 01:42:19,199 okay anything else 2854 01:42:30,709 --> 01:42:25,350 all right 2855 01:42:32,310 --> 01:42:30,719 portion of our our program on time it's 2856 01:42:34,870 --> 01:42:32,320 4 15. 2857 01:42:35,830 --> 01:42:34,880 what we have left 2858 01:42:37,910 --> 01:42:35,840 is 2859 01:42:39,750 --> 01:42:37,920 first of all there was one presenter 2860 01:42:42,629 --> 01:42:39,760 joel cersel 2861 01:42:43,990 --> 01:42:42,639 who had a presentation another session 2862 01:42:46,149 --> 01:42:44,000 that he really feels like belongs here 2863 01:42:47,990 --> 01:42:46,159 so i want to give him five minutes or so 2864 01:42:50,070 --> 01:42:48,000 to be able to give a brief 2865 01:42:52,470 --> 01:42:50,080 uh talk of that and romero would like to 2866 01:42:54,550 --> 01:42:52,480 help ask your help for that um we also 2867 01:42:55,830 --> 01:42:54,560 need to go back and and address some of 2868 01:42:58,390 --> 01:42:55,840 the questions and several of the first 2869 01:43:00,149 --> 01:42:58,400 presenters uh didn't have a chance to to 2870 01:43:03,350 --> 01:43:00,159 receive questions and then the third 2871 01:43:05,750 --> 01:43:03,360 thing um between now and 5 30 or is to 2872 01:43:07,990 --> 01:43:05,760 talk through some key top you know 2873 01:43:11,510 --> 01:43:08,000 preparations for wednesday's outbrief 2874 01:43:13,669 --> 01:43:11,520 um and we have um 2875 01:43:16,149 --> 01:43:13,679 we we have a start at that that we'll 2876 01:43:18,470 --> 01:43:16,159 talk from so but i think as long as it's 2877 01:43:20,390 --> 01:43:18,480 been right here i think at the risk of 2878 01:43:22,550 --> 01:43:20,400 losing the audience we'll take a short 2879 01:43:23,750 --> 01:43:22,560 break for um 2880 01:43:26,950 --> 01:43:23,760 10 minutes 2881 01:43:29,590 --> 01:43:26,960 and and try to get back here by 26 after 2882 01:47:11,510 --> 01:43:29,600 so that we start at 4 30. 2883 01:47:11,520 --> 01:47:22,470 figure out 2884 01:47:22,480 --> 01:47:48,390 okay 2885 01:47:48,400 --> 01:48:01,990 i'm done 2886 01:48:02,000 --> 01:48:28,070 lately 2887 01:48:28,080 --> 01:48:51,350 is 2888 01:48:51,360 --> 01:49:09,510 foreign 2889 01:49:09,520 --> 01:49:36,229 and uh 2890 01:49:36,239 --> 01:49:50,870 um 2891 01:49:50,880 --> 01:50:09,270 you check that out 2892 01:50:56,550 --> 01:50:28,629 okay 2893 01:56:50,229 --> 01:50:58,910 so we were talking about 2894 01:56:53,109 --> 01:56:51,750 no that's good 2895 01:56:56,709 --> 01:56:53,119 all right um 2896 01:56:59,270 --> 01:56:56,719 as we said uh we have one uh edition for 2897 01:57:01,350 --> 01:56:59,280 a short discussion by dr joel cercelle 2898 01:57:02,950 --> 01:57:01,360 he's um his his paper is in another 2899 01:57:04,149 --> 01:57:02,960 session but it really fits better here 2900 01:57:05,350 --> 01:57:04,159 so we're going to give him about five 2901 01:57:06,629 --> 01:57:05,360 minutes to talk 2902 01:57:08,070 --> 01:57:06,639 through that then we'll go back through 2903 01:57:10,470 --> 01:57:08,080 some of the questions that we hadn't 2904 01:57:12,629 --> 01:57:10,480 gotten to and then we'll talk through 2905 01:57:14,629 --> 01:57:12,639 what we want to talk about on wednesday 2906 01:57:16,790 --> 01:57:14,639 dr cersel is the president and founder 2907 01:57:18,950 --> 01:57:16,800 of ics associates which specializes in 2908 01:57:20,550 --> 01:57:18,960 helping clients become more innovative 2909 01:57:22,310 --> 01:57:20,560 and effective at systems engineering and 2910 01:57:24,470 --> 01:57:22,320 project management 2911 01:57:25,910 --> 01:57:24,480 joel has over 25 years of experience 2912 01:57:28,070 --> 01:57:25,920 developing advanced technology and 2913 01:57:30,629 --> 01:57:28,080 innovation products he spent 14 years at 2914 01:57:32,550 --> 01:57:30,639 jpl and two years as a senior program 2915 01:57:34,709 --> 01:57:32,560 manager for the air force joel received 2916 01:57:36,470 --> 01:57:34,719 his phd and master's in mechanical 2917 01:57:38,229 --> 01:57:36,480 engineering from caltech with his 2918 01:57:40,310 --> 01:57:38,239 doctoral dissertation in space 2919 01:57:41,589 --> 01:57:40,320 propulsion plasma physics 2920 01:57:46,229 --> 01:57:41,599 joel 2921 01:57:49,510 --> 01:57:47,910 i'll go fast 2922 01:58:00,390 --> 01:57:49,520 because i'm not going to say much i'm 2923 01:58:04,470 --> 01:58:02,390 has been put in place 2924 01:58:07,270 --> 01:58:04,480 one of the co-architects of this concept 2925 01:58:10,550 --> 01:58:07,280 is james french who you may know from 2926 01:58:13,270 --> 01:58:10,560 being the architect of um 2927 01:58:15,350 --> 01:58:13,280 blue origins satellites he was also the 2928 01:58:16,390 --> 01:58:15,360 chief engineer of amrock the company 2929 01:58:18,550 --> 01:58:16,400 that made the 2930 01:58:20,870 --> 01:58:18,560 hybrid rockets that are in use in virgin 2931 01:58:22,870 --> 01:58:20,880 galactic systems 2932 01:58:24,870 --> 01:58:22,880 another person who worked with us is 2933 01:58:27,430 --> 01:58:24,880 greg maranac who was 2934 01:58:28,790 --> 01:58:27,440 one of the co-founders of the xprize 2935 01:58:31,350 --> 01:58:28,800 foundation 2936 01:58:33,270 --> 01:58:31,360 so we're very excited about this it's a 2937 01:58:35,910 --> 01:58:33,280 radically different approach 2938 01:58:37,350 --> 01:58:35,920 for nearest object redirection 2939 01:58:39,589 --> 01:58:37,360 i'm just going to tell you a couple 2940 01:58:41,189 --> 01:58:39,599 simple things about it number one is 2941 01:58:44,149 --> 01:58:41,199 what is the goal of it we call it 2942 01:58:47,669 --> 01:58:45,430 not to be confused with honeybee 2943 01:58:49,910 --> 01:58:47,679 robotics which is spelled differently or 2944 01:58:51,350 --> 01:58:49,920 there's a bumblebee asteroid deflection 2945 01:58:52,870 --> 01:58:51,360 system that they've been working on in 2946 01:58:54,310 --> 01:58:52,880 scotland that's not presented here this 2947 01:58:55,189 --> 01:58:54,320 year this week 2948 01:58:57,350 --> 01:58:55,199 um 2949 01:58:59,589 --> 01:58:57,360 because it it basically goes out and 2950 01:59:01,270 --> 01:58:59,599 gathers things in a way that's analogous 2951 01:59:03,589 --> 01:59:01,280 to bees and that's all i'm going to say 2952 01:59:05,189 --> 01:59:03,599 about the technical approach 2953 01:59:06,950 --> 01:59:05,199 i'm going to say why we're doing it's 2954 01:59:09,270 --> 01:59:06,960 very important to ask the question why 2955 01:59:10,629 --> 01:59:09,280 are we doing this i think arm is a very 2956 01:59:12,790 --> 01:59:10,639 cool mission 2957 01:59:15,109 --> 01:59:12,800 as currently conceived and the why that 2958 01:59:17,430 --> 01:59:15,119 nasa has is to give astronauts something 2959 01:59:19,109 --> 01:59:17,440 to do that's really cool if that's what 2960 01:59:21,430 --> 01:59:19,119 you want to do but we have a different 2961 01:59:23,589 --> 01:59:21,440 goal which and if again it may also give 2962 01:59:24,629 --> 01:59:23,599 astronauts something much more powerful 2963 01:59:25,990 --> 01:59:24,639 to do 2964 01:59:28,550 --> 01:59:26,000 um so i'm going to give you a 2965 01:59:30,149 --> 01:59:28,560 description of the mission l attributes 2966 01:59:32,950 --> 01:59:30,159 this is the why 2967 01:59:34,550 --> 01:59:32,960 this is the how what i'm not going to do 2968 01:59:36,790 --> 01:59:34,560 is i'm not going to give you the what 2969 01:59:39,750 --> 01:59:36,800 how does it work technically 2970 01:59:41,030 --> 01:59:39,760 that has to go for another place 2971 01:59:42,229 --> 01:59:41,040 um 2972 01:59:44,390 --> 01:59:42,239 talk a little bit about what it would 2973 01:59:45,510 --> 01:59:44,400 take to be successful from the larger 2974 01:59:47,109 --> 01:59:45,520 perspective 2975 01:59:48,310 --> 01:59:47,119 and i'm going to tell you how to contact 2976 01:59:49,990 --> 01:59:48,320 me if you want to discuss the 2977 01:59:50,870 --> 01:59:50,000 proprietary systems and approaches 2978 01:59:52,870 --> 01:59:50,880 because 2979 01:59:57,030 --> 01:59:52,880 when we do this it's going to change 2980 01:59:58,709 --> 01:59:57,040 everything about everything in space 2981 02:00:00,470 --> 01:59:58,719 so why 2982 02:00:02,589 --> 02:00:00,480 the goal is simple 2983 02:00:04,790 --> 02:00:02,599 to make humanity a species that uses 2984 02:00:06,950 --> 02:00:04,800 extraterrestrial resources for practical 2985 02:00:08,950 --> 02:00:06,960 purposes but not to do it with pie in 2986 02:00:10,870 --> 02:00:08,960 the sky to do it with a system that 2987 02:00:14,390 --> 02:00:10,880 today every element of the system is at 2988 02:00:16,470 --> 02:00:14,400 trl4 or above 2989 02:00:18,870 --> 02:00:16,480 it's a and to pilot 2990 02:00:20,950 --> 02:00:18,880 that means to really no no kidding do it 2991 02:00:23,270 --> 02:00:20,960 an affordable method 2992 02:00:25,750 --> 02:00:23,280 to use in a practical way hundreds of 2993 02:00:27,350 --> 02:00:25,760 tons of extraterrestrial resources which 2994 02:00:29,430 --> 02:00:27,360 honeybee does 2995 02:00:31,030 --> 02:00:29,440 to radically reduce and once we do that 2996 02:00:34,229 --> 02:00:31,040 it will radically reduce the cost of 2997 02:00:35,669 --> 02:00:34,239 space operations for all kinds of 2998 02:00:39,430 --> 02:00:35,679 further missions 2999 02:00:41,510 --> 02:00:39,440 so for example when honeybee is in place 3000 02:00:44,950 --> 02:00:41,520 we will have demonstrated the ability to 3001 02:00:47,189 --> 02:00:44,960 essentially convert 1000 ton neo 3002 02:00:49,109 --> 02:00:47,199 to a propellant depot that could be used 3003 02:00:51,430 --> 02:00:49,119 to fill the tanks of a manned mars 3004 02:00:54,070 --> 02:00:51,440 mission at the top of the gravity well 3005 02:00:56,149 --> 02:00:54,080 that collapses the cost of human 3006 02:00:57,910 --> 02:00:56,159 exploration of mars 3007 02:00:59,189 --> 02:00:57,920 it allows you it puts it allows you to 3008 02:01:01,350 --> 02:00:59,199 put in place an inexpensive 3009 02:01:04,070 --> 02:01:01,360 transportation system to go anywhere in 3010 02:01:05,430 --> 02:01:04,080 cis lunar space which includes leo to 3011 02:01:07,910 --> 02:01:05,440 geo 3012 02:01:09,510 --> 02:01:07,920 what it therefore a falcon 9 would have 3013 02:01:12,870 --> 02:01:09,520 the ability to launch 3014 02:01:15,510 --> 02:01:12,880 two 5 000 kilogram geos 3015 02:01:17,990 --> 02:01:15,520 and that's the big class and a 2 500 3016 02:01:20,149 --> 02:01:18,000 kilogram geo all on one falcon line 3017 02:01:21,910 --> 02:01:20,159 launch so someone who is in that 3018 02:01:24,149 --> 02:01:21,920 business tell me how much that saves in 3019 02:01:25,910 --> 02:01:24,159 launch cost i don't know the number i'm 3020 02:01:28,950 --> 02:01:25,920 assuming it's somewhere in the 10 to the 3021 02:01:33,750 --> 02:01:31,430 what does honeybee do it captures 3022 02:01:35,109 --> 02:01:33,760 a neo into cis lunar space a lot like 3023 02:01:37,350 --> 02:01:35,119 arm 3024 02:01:40,390 --> 02:01:37,360 but it's radically different 3025 02:01:43,109 --> 02:01:40,400 in the sense that it uses very simple 3026 02:01:44,950 --> 02:01:43,119 common sense systems nothing 3027 02:01:47,109 --> 02:01:44,960 suffic nothing very high tech or 3028 02:01:49,189 --> 02:01:47,119 advanced there's no 3029 02:01:51,589 --> 02:01:49,199 high power electric processing there's 3030 02:01:54,149 --> 02:01:51,599 no 50 kilowatt solar array there's no 3031 02:01:56,149 --> 02:01:54,159 plasma propulsion and john brophy 3032 02:01:57,589 --> 02:01:56,159 remembers when we did n star i mean i 3033 02:01:59,350 --> 02:01:57,599 i'm a big passionate believer in 3034 02:02:02,550 --> 02:01:59,360 electric propulsion i just don't think 3035 02:02:04,229 --> 02:02:02,560 it's the right choice for this mission 3036 02:02:07,430 --> 02:02:04,239 however unlike arm it does require 3037 02:02:10,149 --> 02:02:07,440 careful selection of the target object 3038 02:02:12,229 --> 02:02:10,159 and so i'm a big believer in the talk 3039 02:02:14,310 --> 02:02:12,239 that mr gump gave 3040 02:02:15,270 --> 02:02:14,320 that said you have to do prospecting 3041 02:02:17,189 --> 02:02:15,280 first 3042 02:02:19,669 --> 02:02:17,199 i used to have a manager who had used to 3043 02:02:21,109 --> 02:02:19,679 assign me to do powerpoint presentations 3044 02:02:22,870 --> 02:02:21,119 and we called it the bring me a rock 3045 02:02:24,310 --> 02:02:22,880 powerpoint method he'd say i want a 3046 02:02:25,990 --> 02:02:24,320 powerpoint presentation about something 3047 02:02:27,830 --> 02:02:26,000 i don't know what it is so i'd bring it 3048 02:02:29,270 --> 02:02:27,840 to him and then he'd have me redo it a 3049 02:02:30,870 --> 02:02:29,280 hundred times if we called it bring me a 3050 02:02:32,629 --> 02:02:30,880 rock bring me a rock maybe a way for 3051 02:02:35,189 --> 02:02:32,639 managers to get powerpoint presentations 3052 02:02:38,390 --> 02:02:35,199 done it should not be the way that nasa 3053 02:02:41,189 --> 02:02:38,400 plans a multi-billion dollar mission 3054 02:02:43,750 --> 02:02:41,199 so um at the technical level if you 3055 02:02:46,149 --> 02:02:43,760 compare honeybee to the baseline arm 3056 02:02:47,589 --> 02:02:46,159 mission concept instead of delivering 3057 02:02:49,109 --> 02:02:47,599 and john i read your different papers 3058 02:02:50,709 --> 02:02:49,119 like there's a little spread in the data 3059 02:02:52,870 --> 02:02:50,719 in terms of the cost it's an evolving 3060 02:02:55,430 --> 02:02:52,880 concept that's all good instead of 3061 02:02:56,910 --> 02:02:55,440 delivering in round numbers 15 tons by 3062 02:02:59,750 --> 02:02:56,920 the way ton is 3063 02:03:01,589 --> 02:02:59,760 t-o-n-n-e-s i just i noticed a lot of 3064 02:03:05,030 --> 02:03:01,599 typos on that in people's talks and i'm 3065 02:03:06,470 --> 02:03:05,040 bad at spelling so instead of 15 tons to 3066 02:03:08,629 --> 02:03:06,480 low c3 3067 02:03:10,390 --> 02:03:08,639 you require only about 3000 kilograms to 3068 02:03:14,310 --> 02:03:10,400 a low c3 3069 02:03:15,990 --> 02:03:14,320 um instead of a long trip time out and 3070 02:03:17,910 --> 02:03:16,000 back it's short 3071 02:03:19,830 --> 02:03:17,920 and it's short i won't tell you exactly 3072 02:03:21,510 --> 02:03:19,840 how but it's more like a very impulsive 3073 02:03:22,550 --> 02:03:21,520 trajectory 3074 02:03:25,430 --> 02:03:22,560 um 3075 02:03:27,669 --> 02:03:25,440 probably reduces the cost a lot and then 3076 02:03:29,830 --> 02:03:27,679 very oh interesting it 3077 02:03:31,350 --> 02:03:29,840 switching from mac to windows to stored 3078 02:03:33,350 --> 02:03:31,360 the 3079 02:03:35,350 --> 02:03:33,360 formatting but anyway instead of 3080 02:03:36,310 --> 02:03:35,360 returning a thousand ton object that now 3081 02:03:37,589 --> 02:03:36,320 you got to figure out what you're going 3082 02:03:40,709 --> 02:03:37,599 to do with it 3083 02:03:43,589 --> 02:03:40,719 it returns the object in such a way that 3084 02:03:46,629 --> 02:03:43,599 we have a functioning fully functioning 3085 02:03:48,709 --> 02:03:46,639 orbiting propellant depot 3086 02:03:50,149 --> 02:03:48,719 um how to get it done i totally agree 3087 02:03:52,310 --> 02:03:50,159 with mr gump's 3088 02:03:54,310 --> 02:03:52,320 point on this it's got to be about 3089 02:03:56,310 --> 02:03:54,320 public private partnership 3090 02:03:59,189 --> 02:03:56,320 a combination of venture capitalists 3091 02:04:01,669 --> 02:03:59,199 aerospace companies nasa and jpl i think 3092 02:04:03,270 --> 02:04:01,679 that's the right way to do it it's what 3093 02:04:04,870 --> 02:04:03,280 we need to do is we need to pull 3094 02:04:07,750 --> 02:04:04,880 together as a community to understand 3095 02:04:08,550 --> 02:04:07,760 it's time to stop screwing around 3096 02:04:10,069 --> 02:04:08,560 with 3097 02:04:12,870 --> 02:04:10,079 high paid tourists that we called 3098 02:04:14,709 --> 02:04:12,880 astronauts in space it started time to 3099 02:04:15,750 --> 02:04:14,719 start doing something really important 3100 02:04:17,189 --> 02:04:15,760 in space 3101 02:04:19,109 --> 02:04:17,199 and this is this is the beginning of 3102 02:04:20,950 --> 02:04:19,119 that process 3103 02:04:22,950 --> 02:04:20,960 so what i'm asking you to do is i'm 3104 02:04:25,030 --> 02:04:22,960 asking you to think not like a 20th 3105 02:04:28,229 --> 02:04:25,040 century architect 3106 02:04:30,069 --> 02:04:28,239 enterprise but like a 21st century 3107 02:04:31,750 --> 02:04:30,079 enterprise if you're interested in 3108 02:04:34,229 --> 02:04:31,760 finding out about it we can talk about 3109 02:04:35,990 --> 02:04:34,239 it under nda and that's my contact 3110 02:04:43,669 --> 02:04:36,000 information so 3111 02:04:47,510 --> 02:04:45,510 all right um 3112 02:04:49,189 --> 02:04:47,520 any questions for a quick question for 3113 02:04:53,109 --> 02:04:49,199 joel or 3114 02:04:54,870 --> 02:04:53,119 we'll go on to um 3115 02:04:56,790 --> 02:04:54,880 okay then we'll go on to 3116 02:04:58,470 --> 02:04:56,800 revisiting uh 3117 02:04:59,830 --> 02:04:58,480 romero could you bring up the 3118 02:05:02,950 --> 02:04:59,840 introduction 3119 02:05:02,960 --> 02:05:08,790 my contact information is 3120 02:05:14,149 --> 02:05:11,910 and then if you would go ahead um 3121 02:05:16,629 --> 02:05:14,159 two slides 3122 02:05:18,550 --> 02:05:16,639 just as a reminder for um this will also 3123 02:05:19,430 --> 02:05:18,560 be a good time place for us to start 3124 02:05:23,430 --> 02:05:19,440 when we 3125 02:05:25,910 --> 02:05:23,440 set the question 3126 02:05:28,229 --> 02:05:25,920 so what i'd like to do is is see where 3127 02:05:29,750 --> 02:05:28,239 we get to in the next 15 minutes or so 3128 02:05:32,069 --> 02:05:29,760 or if we don't have enough questions you 3129 02:05:34,069 --> 02:05:32,079 know we'll go into the next phase but 3130 02:05:36,709 --> 02:05:34,079 so does anyone want to bring back one of 3131 02:05:40,310 --> 02:05:36,719 the presenters or or bring up a point we 3132 02:05:42,310 --> 02:05:40,320 do have several um from um the chat and 3133 02:05:43,350 --> 02:05:42,320 we can start with those unless somebody 3134 02:05:45,990 --> 02:05:43,360 has something 3135 02:05:53,750 --> 02:05:46,000 so go ahead heather if you'd go to a mic 3136 02:05:57,669 --> 02:05:55,350 so i'm going to just start at the 3137 02:05:59,750 --> 02:05:57,679 beginning so john brophy there was 3138 02:06:01,270 --> 02:05:59,760 someone who addressed does the material 3139 02:06:03,830 --> 02:06:01,280 of the bag need to be electrically 3140 02:06:09,589 --> 02:06:03,840 conductive to prevent static charge 3141 02:06:09,599 --> 02:06:12,149 yes 3142 02:06:16,149 --> 02:06:14,310 okay well that was quick all right don't 3143 02:06:18,229 --> 02:06:16,159 sit down don't sit down you're not 3144 02:06:19,830 --> 02:06:18,239 you've got a couple here so somebody 3145 02:06:23,350 --> 02:06:19,840 wants to know how you match the spin 3146 02:06:27,350 --> 02:06:25,990 okay so to match the spin rate um 3147 02:06:29,750 --> 02:06:27,360 you just have to 3148 02:06:32,390 --> 02:06:29,760 there's attitude control thrusters on 3149 02:06:33,990 --> 02:06:32,400 the spacecraft and so you just spin up 3150 02:06:35,350 --> 02:06:34,000 use that to spin up the spacecraft to 3151 02:06:38,390 --> 02:06:35,360 the same 3152 02:06:39,669 --> 02:06:38,400 rotation rate as the asteroid 3153 02:06:42,830 --> 02:06:39,679 we're matching the instantaneous 3154 02:06:44,390 --> 02:06:42,840 rotation right you might want to verify 3155 02:06:46,229 --> 02:06:44,400 yeah 3156 02:06:48,470 --> 02:06:46,239 okay so people are adding more details 3157 02:06:50,229 --> 02:06:48,480 so we watch it long enough to 3158 02:06:51,910 --> 02:06:50,239 be able to know exactly it's spin 3159 02:06:54,229 --> 02:06:51,920 characteristic and project that into the 3160 02:06:56,790 --> 02:06:54,239 future and so that you can then 3161 02:06:58,149 --> 02:06:56,800 match the instantaneous spin right at 3162 02:07:00,149 --> 02:06:58,159 the time you're going to go grab the 3163 02:07:01,910 --> 02:07:00,159 ester and that's for high spin rates 3164 02:07:03,510 --> 02:07:01,920 right for lower spin rates we don't even 3165 02:07:07,030 --> 02:07:03,520 have to bother with that you sure that 3166 02:07:10,229 --> 02:07:08,870 you were presenting john so you were the 3167 02:07:13,510 --> 02:07:10,239 lucky one 3168 02:07:15,189 --> 02:07:13,520 okay uh so then there was a like four or 3169 02:07:17,350 --> 02:07:15,199 five or six different comments that came 3170 02:07:19,990 --> 02:07:17,360 in about electromagnetism so i'm going 3171 02:07:21,350 --> 02:07:20,000 to just kind of describe in general what 3172 02:07:23,910 --> 02:07:21,360 they were and then we can have that 3173 02:07:25,990 --> 02:07:23,920 discussion so should electromagnetism be 3174 02:07:27,109 --> 02:07:26,000 used as a backup to the capture bag as a 3175 02:07:30,709 --> 02:07:27,119 secure 3176 02:07:32,550 --> 02:07:30,719 the um asteroid 3177 02:07:34,069 --> 02:07:32,560 magnetic components within a bag could 3178 02:07:35,510 --> 02:07:34,079 help de-spin 3179 02:07:37,589 --> 02:07:35,520 concept 3180 02:07:40,709 --> 02:07:37,599 generate electromagnetic charge for tow 3181 02:07:42,390 --> 02:07:40,719 and capture what about a tractor beam 3182 02:07:44,790 --> 02:07:42,400 um 3183 02:07:46,470 --> 02:07:44,800 i like the tractor building 3184 02:07:48,750 --> 02:07:46,480 so let's see 3185 02:07:50,550 --> 02:07:48,760 i those were sort of the gist of the 3186 02:07:52,790 --> 02:07:50,560 electromagnetism but there were quite a 3187 02:07:53,830 --> 02:07:52,800 few different threads about that so okay 3188 02:07:56,149 --> 02:07:53,840 so the 3189 02:07:58,550 --> 02:07:56,159 i think the the notion is can you use 3190 02:08:00,470 --> 02:07:58,560 some kind of electromagnetic forces on 3191 02:08:02,870 --> 02:08:00,480 the asteroid to help control it or 3192 02:08:05,030 --> 02:08:02,880 de-tumble it and uh 3193 02:08:06,790 --> 02:08:05,040 that requires you to know a lot about 3194 02:08:08,550 --> 02:08:06,800 the asteroid and how conductive it is 3195 02:08:10,390 --> 02:08:08,560 and how 3196 02:08:11,669 --> 02:08:10,400 you know how you can apply those forces 3197 02:08:12,950 --> 02:08:11,679 so 3198 02:08:15,030 --> 02:08:12,960 probably 3199 02:08:17,030 --> 02:08:15,040 wouldn't be the first approach that we 3200 02:08:20,950 --> 02:08:17,040 would attempt to capture an asteroid 3201 02:08:26,149 --> 02:08:24,149 uh there was a question about if you 3202 02:08:27,910 --> 02:08:26,159 were attached to a nickel iron asteroid 3203 02:08:34,550 --> 02:08:27,920 could you chemically produce hydrogen 3204 02:08:39,430 --> 02:08:35,589 no 3205 02:08:41,350 --> 02:08:39,440 but it would be awesome to find a a 3206 02:08:44,390 --> 02:08:41,360 whole nickel iron asteroid but we 3207 02:08:47,750 --> 02:08:44,400 probably wouldn't bring that back 3208 02:08:53,270 --> 02:08:50,390 all right we talked about that one um 3209 02:08:54,550 --> 02:08:53,280 there was sort of a discussion 3210 02:08:55,990 --> 02:08:54,560 and there really wasn't a question that 3211 02:08:58,069 --> 02:08:56,000 came out of it there was a discussion 3212 02:09:00,069 --> 02:08:58,079 that might be worth capturing about the 3213 02:09:01,910 --> 02:09:00,079 trade between designing a vehicle for 3214 02:09:04,629 --> 02:09:01,920 worst case masses when you have large 3215 02:09:06,950 --> 02:09:04,639 uncertainties versus funding precursor 3216 02:09:09,350 --> 02:09:06,960 robotic precursor missions so there was 3217 02:09:11,270 --> 02:09:09,360 a quite a few different threads about 3218 02:09:12,950 --> 02:09:11,280 that and and um 3219 02:09:15,189 --> 02:09:12,960 in discussing with jim he thought we 3220 02:09:17,109 --> 02:09:15,199 ought to just capture that as a yeah 3221 02:09:18,950 --> 02:09:17,119 well that i mean that that is a you know 3222 02:09:20,229 --> 02:09:18,960 that's a serious issue and that is one 3223 02:09:23,430 --> 02:09:20,239 of the key 3224 02:09:25,189 --> 02:09:23,440 uh drivers for the characterization uh 3225 02:09:25,990 --> 02:09:25,199 the observation campaign 3226 02:09:27,510 --> 02:09:26,000 uh 3227 02:09:29,830 --> 02:09:27,520 the characterization part of that 3228 02:09:32,550 --> 02:09:29,840 campaign and so you have to 3229 02:09:35,430 --> 02:09:32,560 do the right characterizations to 3230 02:09:37,910 --> 02:09:35,440 to limit the uncertainty in the size and 3231 02:09:41,109 --> 02:09:37,920 mass and spin state of the object so 3232 02:09:41,990 --> 02:09:41,119 that it's within the capabilities of 3233 02:09:44,629 --> 02:09:42,000 your 3234 02:09:45,669 --> 02:09:44,639 flight system with appropriate margins 3235 02:09:46,629 --> 02:09:45,679 and 3236 02:09:50,470 --> 02:09:46,639 in the 3237 02:09:52,709 --> 02:09:50,480 period over the last uh 3238 02:09:55,910 --> 02:09:52,719 uh seven or eight months it's clear that 3239 02:09:57,109 --> 02:09:55,920 that such an observation campaign is is 3240 02:09:59,030 --> 02:09:57,119 possible 3241 02:10:01,109 --> 02:09:59,040 and and is 3242 02:10:02,870 --> 02:10:01,119 and part of the reason for that is 3243 02:10:04,229 --> 02:10:02,880 uh you know someone had mentioned in one 3244 02:10:06,069 --> 02:10:04,239 of their talks that there weren't a lot 3245 02:10:07,589 --> 02:10:06,079 of these small objects but uh the 3246 02:10:09,510 --> 02:10:07,599 current population models you know 3247 02:10:11,270 --> 02:10:09,520 suggested basically that all the 3248 02:10:14,149 --> 02:10:11,280 near-earth asteroids to first order are 3249 02:10:15,910 --> 02:10:14,159 small and there are just a scattering of 3250 02:10:16,950 --> 02:10:15,920 larger ones and so 3251 02:10:20,149 --> 02:10:16,960 um 3252 02:10:22,950 --> 02:10:20,159 there are lots of objects potentially to 3253 02:10:25,189 --> 02:10:22,960 to discover and um 3254 02:10:26,709 --> 02:10:25,199 and characterize so we can as i 3255 02:10:28,950 --> 02:10:26,719 mentioned earlier there's the likelihood 3256 02:10:30,790 --> 02:10:28,960 that we'd have 15 to 20 3257 02:10:35,189 --> 02:10:30,800 good well characterized objects that we 3258 02:10:40,629 --> 02:10:38,310 there were a few comments about 3259 02:10:41,430 --> 02:10:40,639 having the mission thought out further 3260 02:10:43,189 --> 02:10:41,440 for 3261 02:10:45,910 --> 02:10:43,199 better integration and long-term 3262 02:10:47,430 --> 02:10:45,920 purposes for the asteroid just a couple 3263 02:10:49,830 --> 02:10:47,440 along that thread 3264 02:10:52,069 --> 02:10:49,840 um and i have a couple of my own though 3265 02:10:54,950 --> 02:10:52,079 that was the end of the virtual ones 3266 02:10:57,350 --> 02:10:54,960 okay if that's okay so um 3267 02:10:59,030 --> 02:10:57,360 the the one was for boeing and i was 3268 02:11:01,910 --> 02:10:59,040 wondering what updates you've done to 3269 02:11:11,830 --> 02:11:01,920 your arnd sensor suite since orbital 3270 02:11:14,470 --> 02:11:12,550 uh 3271 02:11:16,870 --> 02:11:14,480 actually we've done we've done quite a 3272 02:11:18,229 --> 02:11:16,880 lot uh as i mentioned we're uh we're 3273 02:11:21,430 --> 02:11:18,239 developing the vesta system for 3274 02:11:23,109 --> 02:11:21,440 commercial crew and so uh we are headed 3275 02:11:25,830 --> 02:11:23,119 for a critical design review on that 3276 02:11:27,350 --> 02:11:25,840 system here in uh in december 3277 02:11:28,870 --> 02:11:27,360 so that's uh 3278 02:11:32,390 --> 02:11:28,880 that could give you a sense of the 3279 02:11:33,510 --> 02:11:32,400 maturity so the uh the sensors uh three 3280 02:11:35,990 --> 02:11:33,520 different sensor types are in 3281 02:11:39,910 --> 02:11:36,000 development uh the ones i talked about 3282 02:11:44,229 --> 02:11:41,510 beyond that we've done quite a lot of 3283 02:11:46,310 --> 02:11:44,239 work on on the software uh which we 3284 02:11:48,709 --> 02:11:46,320 which we call this star that initially 3285 02:11:50,870 --> 02:11:48,719 flew on orbital express and since then 3286 02:11:53,510 --> 02:11:50,880 we've we've been uh maturing that 3287 02:11:54,950 --> 02:11:53,520 software to make it specifically 3288 02:11:57,910 --> 02:11:54,960 applicable to the international space 3289 02:11:59,430 --> 02:11:57,920 station and so a lot of the the track 3290 02:12:00,149 --> 02:11:59,440 modes that uh 3291 02:12:01,830 --> 02:12:00,159 uh 3292 02:12:03,189 --> 02:12:01,840 there have been papers written you can 3293 02:12:06,470 --> 02:12:03,199 look at this but the different track 3294 02:12:08,229 --> 02:12:06,480 modes that we had on orbital express are 3295 02:12:10,390 --> 02:12:08,239 now being updated 3296 02:12:12,870 --> 02:12:10,400 uh including specific feature track 3297 02:12:13,750 --> 02:12:12,880 modes that are applicable to station and 3298 02:12:19,109 --> 02:12:13,760 those 3299 02:12:20,709 --> 02:12:19,119 are also applicable to natural bodies 3300 02:12:22,069 --> 02:12:20,719 the sorts of 3301 02:12:23,589 --> 02:12:22,079 you know you're looking for features 3302 02:12:24,950 --> 02:12:23,599 they don't have to be any particular 3303 02:12:26,870 --> 02:12:24,960 feature 3304 02:12:28,790 --> 02:12:26,880 so there's a lot of flexibility there in 3305 02:12:30,950 --> 02:12:28,800 terms of what what the details of those 3306 02:12:31,910 --> 02:12:30,960 those features are and we're also doing 3307 02:12:33,350 --> 02:12:31,920 uh 3308 02:12:34,390 --> 02:12:33,360 you know integrated testing in the 3309 02:12:36,229 --> 02:12:34,400 laboratory 3310 02:12:39,430 --> 02:12:36,239 and that's going on today 3311 02:12:41,109 --> 02:12:39,440 so a good bit of 3312 02:12:43,830 --> 02:12:41,119 what i what i talked about there's 3313 02:12:45,910 --> 02:12:43,840 actually hardware in the lab today and 3314 02:12:47,990 --> 02:12:45,920 software integrated in the lab today 3315 02:12:49,270 --> 02:12:48,000 that's doing doing testing on an optical 3316 02:12:52,069 --> 02:12:49,280 range 3317 02:12:54,550 --> 02:12:52,079 thank you and are they the same 3318 02:12:57,109 --> 02:12:54,560 exact sensors or you've updated them the 3319 02:12:58,390 --> 02:12:57,119 same class as i they are updated from 3320 02:13:01,270 --> 02:12:58,400 what we flew on 3321 02:13:03,270 --> 02:13:01,280 orbital express yeah 3322 02:13:05,350 --> 02:13:03,280 it's uh you i think that you mentioned 3323 02:13:07,270 --> 02:13:05,360 one of the sensors is a 3d lighter is 3324 02:13:08,870 --> 02:13:07,280 that scanning or flash or 3325 02:13:11,270 --> 02:13:08,880 uh 3326 02:13:16,550 --> 02:13:11,280 yeah so so at this point let me let me 3327 02:13:21,270 --> 02:13:18,709 that i i probably like to not say right 3328 02:13:22,790 --> 02:13:21,280 now but but 3329 02:13:24,790 --> 02:13:22,800 okay 3330 02:13:25,990 --> 02:13:24,800 but you didn't have one in orbital 3331 02:13:27,589 --> 02:13:26,000 express 3332 02:13:29,750 --> 02:13:27,599 we had a we had a lidar on orbital 3333 02:13:32,069 --> 02:13:29,760 express we had a rangefinder that was a 3334 02:13:34,310 --> 02:13:32,079 scalar that delivered a scalar range so 3335 02:13:38,470 --> 02:13:34,320 this is a this is this is a 3d yeah this 3336 02:13:43,830 --> 02:13:40,310 all right my next question was sort of 3337 02:13:46,470 --> 02:13:43,840 general there were several r d sensor 3338 02:13:49,270 --> 02:13:46,480 presentations made for sort of a suite 3339 02:13:51,830 --> 02:13:49,280 of sensors and i noticed some contained 3340 02:13:53,510 --> 02:13:51,840 ir cameras and some contain only visible 3341 02:13:55,990 --> 02:13:53,520 cameras and we've had a lot of 3342 02:13:57,990 --> 02:13:56,000 discussion and debate about that and 3343 02:13:59,830 --> 02:13:58,000 i don't know if it's appropriate to just 3344 02:14:01,910 --> 02:13:59,840 capture it or if if anyone in the room 3345 02:14:03,750 --> 02:14:01,920 wants a comment about who did include an 3346 02:14:06,229 --> 02:14:03,760 ir camera in their suite the benefit of 3347 02:14:08,470 --> 02:14:06,239 that versus just the visible camera and 3348 02:14:11,350 --> 02:14:08,480 there are certain obvious benefits but 3349 02:14:13,030 --> 02:14:11,360 if anyone wants to address that 3350 02:14:14,790 --> 02:14:13,040 so since i'm i'm standing at the 3351 02:14:16,709 --> 02:14:14,800 microphone like i could start by saying 3352 02:14:20,629 --> 02:14:16,719 that we we include a a long wave 3353 02:14:26,950 --> 02:14:23,510 and and i sort of said why but uh the 3354 02:14:28,069 --> 02:14:26,960 ability to uh to track at night or in 3355 02:14:29,750 --> 02:14:28,079 poor lighting 3356 02:14:31,750 --> 02:14:29,760 when the uh 3357 02:14:34,470 --> 02:14:31,760 or at or at low sun angles 3358 02:14:38,310 --> 02:14:34,480 is a is a good reason to uh to have the 3359 02:14:40,870 --> 02:14:39,430 okay 3360 02:14:46,310 --> 02:14:40,880 are there questions 3361 02:14:50,709 --> 02:14:49,510 oh we have one go ahead and then 3362 02:14:53,030 --> 02:14:50,719 for the 3363 02:14:54,870 --> 02:14:53,040 baseline arv vehicle we've seen some 3364 02:14:57,430 --> 02:14:54,880 engineering sketches 3365 02:14:59,270 --> 02:14:57,440 can anyone describe what tonnage it's 3366 02:15:01,430 --> 02:14:59,280 designed to retrieve or what delta v's 3367 02:15:04,790 --> 02:15:01,440 it achieves outbound and inbound there 3368 02:15:10,229 --> 02:15:06,950 okay yeah so for the i feel weird 3369 02:15:13,109 --> 02:15:11,350 i'll do this 3370 02:15:15,430 --> 02:15:13,119 okay so the 3371 02:15:18,149 --> 02:15:15,440 for the baseline vehicle it was designed 3372 02:15:23,109 --> 02:15:20,550 asteroid masses up to about a thousand 3373 02:15:25,510 --> 02:15:23,119 metric tons and i say about because it 3374 02:15:27,910 --> 02:15:25,520 depends a lot on the specifics of the 3375 02:15:30,470 --> 02:15:27,920 asteroid and it's its orbit and the 3376 02:15:31,350 --> 02:15:30,480 characteristics and also on when you can 3377 02:15:37,030 --> 02:15:31,360 launch 3378 02:15:38,709 --> 02:15:37,040 forth but so you know roughly a thousand 3379 02:15:40,629 --> 02:15:38,719 metric tons is 3380 02:15:41,750 --> 02:15:40,639 is the limit 3381 02:15:44,149 --> 02:15:41,760 so 3382 02:15:47,750 --> 02:15:44,159 and it it uses we can store up to as i 3383 02:15:50,470 --> 02:15:47,760 said about 10 tons of xenon and 400 tons 3384 02:15:52,629 --> 02:15:50,480 400 kilograms of hydrazine so those all 3385 02:15:55,430 --> 02:15:52,639 fit into that as well as the aster the 3386 02:15:58,229 --> 02:15:55,440 capture mechanism size they're all uh 3387 02:16:00,149 --> 02:15:58,239 interrelated to some degree 3388 02:16:01,109 --> 02:16:00,159 oh i'm sorry yeah the delta v 3389 02:16:03,270 --> 02:16:01,119 uh 3390 02:16:04,470 --> 02:16:03,280 so the inbound delta v is on the order 3391 02:16:07,270 --> 02:16:04,480 of 3392 02:16:09,430 --> 02:16:07,280 100 to 200 meters per second 3393 02:16:12,629 --> 02:16:09,440 that again depends on the asteroid and 3394 02:16:16,550 --> 02:16:12,639 part of that goes to 3395 02:16:19,510 --> 02:16:16,560 getting the asteroid into the long term 3396 02:16:22,550 --> 02:16:19,520 dro after the lunar gravity assist the 3397 02:16:24,550 --> 02:16:22,560 outbound delta v depends on 3398 02:16:26,390 --> 02:16:24,560 whether you're spiraling out from earth 3399 02:16:29,030 --> 02:16:26,400 orbit or just doing the heliocentric 3400 02:16:31,589 --> 02:16:29,040 phase and so it could be 3401 02:16:33,349 --> 02:16:31,599 on the order of four to six kilometers 3402 02:16:35,990 --> 02:16:33,359 per second 3403 02:16:40,950 --> 02:16:36,000 maybe more depending on how low in earth 3404 02:16:40,960 --> 02:16:44,549 questions 3405 02:16:44,559 --> 02:16:57,110 yeah no go ahead you go ahead first 3406 02:17:01,429 --> 02:17:00,150 my question is to some extent rhetoric 3407 02:17:04,629 --> 02:17:01,439 because it 3408 02:17:06,549 --> 02:17:04,639 it is addressed to the whole community 3409 02:17:07,589 --> 02:17:06,559 and this question is 3410 02:17:11,429 --> 02:17:07,599 why 3411 02:17:13,349 --> 02:17:11,439 the as a target orbit was chosen the 3412 02:17:16,150 --> 02:17:13,359 cis lunar orbit 3413 02:17:17,589 --> 02:17:16,160 because some other alternative options 3414 02:17:19,030 --> 02:17:17,599 do exist 3415 02:17:20,950 --> 02:17:19,040 for example 3416 02:17:21,750 --> 02:17:20,960 we can transfer 3417 02:17:33,429 --> 02:17:21,760 the 3418 02:17:34,950 --> 02:17:33,439 with period for example one year and in 3419 02:17:38,629 --> 02:17:34,960 this case 3420 02:17:42,389 --> 02:17:38,639 checked 3421 02:17:43,830 --> 02:17:42,399 is only several meters per second 3422 02:17:47,190 --> 02:17:43,840 and 3423 02:17:50,230 --> 02:17:47,200 we can reach this asteroid 3424 02:17:51,750 --> 02:17:50,240 in the ideal case two times 3425 02:17:54,230 --> 02:17:51,760 per year 3426 02:17:56,389 --> 02:17:54,240 and the arrival delta v 3427 02:18:00,150 --> 02:17:56,399 will be almost in 3428 02:18:02,150 --> 02:18:00,160 ideally zero and departure also 3429 02:18:06,629 --> 02:18:02,160 almost zero 3430 02:18:10,549 --> 02:18:08,230 all right well i'll take a crack at that 3431 02:18:14,389 --> 02:18:10,559 we look we talked a lot about where to 3432 02:18:16,230 --> 02:18:14,399 deliver the asteroid to 3433 02:18:18,389 --> 02:18:16,240 and uh the selection of the distant 3434 02:18:20,150 --> 02:18:18,399 retrograde orbit around the moon 3435 02:18:22,309 --> 02:18:20,160 appeared to be a good choice because it 3436 02:18:24,950 --> 02:18:22,319 was an orbit that 3437 02:18:27,750 --> 02:18:24,960 both the app the asteroid retrieval 3438 02:18:28,549 --> 02:18:27,760 vehicle with a thousand ton asteroid in 3439 02:18:31,429 --> 02:18:28,559 tow 3440 02:18:32,309 --> 02:18:31,439 could get to for a reasonable delta v 3441 02:18:41,349 --> 02:18:32,319 and 3442 02:18:43,589 --> 02:18:41,359 multiple opportunities 3443 02:18:46,629 --> 02:18:43,599 per year 3444 02:18:48,629 --> 02:18:46,639 oh okay yeah and if you lose control 3445 02:18:50,309 --> 02:18:48,639 after a couple hundred years or whatever 3446 02:18:53,190 --> 02:18:50,319 yeah it won't hit the earth even though 3447 02:18:54,709 --> 02:18:53,200 it's of a size it's not a hazard 3448 02:18:58,230 --> 02:18:54,719 it's kind of a belt and suspenders 3449 02:18:58,240 --> 02:19:04,709 all right another question 3450 02:19:08,389 --> 02:19:06,709 yeah everyone's picking on john here but 3451 02:19:11,190 --> 02:19:08,399 uh um 3452 02:19:12,309 --> 02:19:11,200 my question is also to you uh a question 3453 02:19:14,870 --> 02:19:12,319 i'm sorry 3454 02:19:17,429 --> 02:19:14,880 but i was curious though about uh the 3455 02:19:19,110 --> 02:19:17,439 dependence on the arm mission today in 3456 02:19:21,110 --> 02:19:19,120 terms of the sonatic period of the 3457 02:19:22,709 --> 02:19:21,120 asteroids in this sense and that you 3458 02:19:24,070 --> 02:19:22,719 probably have a launch window to launch 3459 02:19:25,750 --> 02:19:24,080 arm okay so then you have to go after 3460 02:19:27,110 --> 02:19:25,760 this asteroid but if you miss it the 3461 02:19:28,150 --> 02:19:27,120 sonatic periods of these objects are 3462 02:19:30,469 --> 02:19:28,160 such that you're never gonna be able to 3463 02:19:32,150 --> 02:19:30,479 go back to that one again so how how 3464 02:19:35,270 --> 02:19:32,160 many backup targets do you need to make 3465 02:19:36,709 --> 02:19:35,280 sure you can fulfill your mission 3466 02:19:39,110 --> 02:19:36,719 one no 3467 02:19:40,629 --> 02:19:39,120 so yeah that's a really good point and 3468 02:19:43,669 --> 02:19:40,639 that's why what you really want what you 3469 02:19:45,669 --> 02:19:43,679 need for a robust mission is to have 3470 02:19:47,589 --> 02:19:45,679 multiple backup targets in multiple 3471 02:19:49,429 --> 02:19:47,599 years 3472 02:19:51,670 --> 02:19:49,439 uh you know the programmatics are such 3473 02:19:53,510 --> 02:19:51,680 that you're we're not sure you know when 3474 02:19:54,870 --> 02:19:53,520 you could launch or if you run into 3475 02:19:56,790 --> 02:19:54,880 technical difficulties and you have to 3476 02:19:59,510 --> 02:19:56,800 launch six months or a year later 3477 02:20:01,510 --> 02:19:59,520 uh you need to have a robust series of 3478 02:20:02,389 --> 02:20:01,520 targets in multiple years that you can 3479 02:20:04,230 --> 02:20:02,399 go to 3480 02:20:06,309 --> 02:20:04,240 and uh and that's why 3481 02:20:08,630 --> 02:20:06,319 um yeah so you know because of the 3482 02:20:10,150 --> 02:20:08,640 synodic period problem if you miss it 3483 02:20:12,710 --> 02:20:10,160 you've got to go to a different target 3484 02:20:14,950 --> 02:20:12,720 unless uh it depends on you know it's 3485 02:20:16,309 --> 02:20:14,960 not quite that black and white because 3486 02:20:18,469 --> 02:20:16,319 if you change launch vehicles if you 3487 02:20:21,429 --> 02:20:18,479 plan to fly in an atlas 5 for example 3488 02:20:23,190 --> 02:20:21,439 and spiral out from earth orbit 3489 02:20:24,950 --> 02:20:23,200 if you miss that launch and you have an 3490 02:20:27,429 --> 02:20:24,960 opportunity to launch on a falcon heavy 3491 02:20:29,830 --> 02:20:27,439 for example you can then 3492 02:20:31,590 --> 02:20:29,840 make up that year to year and a half 3493 02:20:33,030 --> 02:20:31,600 slip by launching by eliminating the 3494 02:20:34,870 --> 02:20:33,040 spiral out time and going directly so 3495 02:20:36,230 --> 02:20:34,880 you have some flexibility there as well 3496 02:20:38,230 --> 02:20:36,240 you may want to talk about the launch 3497 02:20:40,870 --> 02:20:38,240 window in the same 3498 02:20:42,950 --> 02:20:40,880 sense because scp does change the 3499 02:20:45,590 --> 02:20:42,960 dynamics of that significance oh you may 3500 02:20:47,670 --> 02:20:45,600 want to repeat that okay so 3501 02:20:49,429 --> 02:20:47,680 and and jim's right so the other uh 3502 02:20:51,110 --> 02:20:49,439 part of this is uh with electric 3503 02:20:53,670 --> 02:20:51,120 propulsion you get a 3504 02:20:55,750 --> 02:20:53,680 longer launch period than you normally 3505 02:20:57,590 --> 02:20:55,760 get with um uh 3506 02:20:59,830 --> 02:20:57,600 ballistic interplanetary spacecraft and 3507 02:21:02,389 --> 02:20:59,840 so you have additional flexibility don 3508 02:21:03,750 --> 02:21:02,399 is a good example of that 3509 02:21:05,270 --> 02:21:03,760 i won't bore you with all the details 3510 02:21:06,469 --> 02:21:05,280 but at the very end it was going to 3511 02:21:07,830 --> 02:21:06,479 launch in 3512 02:21:09,270 --> 02:21:07,840 the beginning of july and it wound up 3513 02:21:11,349 --> 02:21:09,280 launching at the end of september but it 3514 02:21:13,030 --> 02:21:11,359 could still do this multiple 3515 02:21:14,070 --> 02:21:13,040 main belt asteroid rendezvous mission 3516 02:21:15,670 --> 02:21:14,080 because of the use of electric 3517 02:21:19,349 --> 02:21:15,680 propulsion so you get that added 3518 02:21:24,950 --> 02:21:20,469 okay 3519 02:21:29,270 --> 02:21:27,510 one last one 3520 02:21:31,750 --> 02:21:29,280 we've been talking a lot about solar 3521 02:21:35,190 --> 02:21:31,760 electric propulsion and one of the 3522 02:21:38,230 --> 02:21:35,200 comments early on early comments was 3523 02:21:40,150 --> 02:21:38,240 launching into a highly elliptical orbit 3524 02:21:42,550 --> 02:21:40,160 we've been looking at small orbital 3525 02:21:43,429 --> 02:21:42,560 debris and it's getting a whole lot 3526 02:21:44,550 --> 02:21:43,439 worse 3527 02:21:47,190 --> 02:21:44,560 and 3528 02:21:49,510 --> 02:21:47,200 one of the things that we looked at was 3529 02:21:52,309 --> 02:21:49,520 that a highly elliptical orbit like 3530 02:21:54,790 --> 02:21:52,319 we're planning for sls a couple of the 3531 02:21:57,349 --> 02:21:54,800 first couple of missions gets you out of 3532 02:21:58,150 --> 02:21:57,359 that problem very quickly 3533 02:22:00,710 --> 02:21:58,160 but 3534 02:22:01,750 --> 02:22:00,720 uh is there i've heard a lot of comments 3535 02:22:02,469 --> 02:22:01,760 about 3536 02:22:05,429 --> 02:22:02,479 the 3537 02:22:07,110 --> 02:22:05,439 van allen belts and trying to avoid 3538 02:22:10,309 --> 02:22:07,120 exposure to that 3539 02:22:12,710 --> 02:22:10,319 has the small orbital debris exposure 3540 02:22:13,910 --> 02:22:12,720 which is getting worse and worse as time 3541 02:22:17,110 --> 02:22:13,920 goes by 3542 02:22:21,110 --> 02:22:17,120 has anybody been figuring that into 3543 02:22:23,670 --> 02:22:21,120 how they do their launch to avoid 3544 02:22:31,190 --> 02:22:23,680 having to slowly spiral out through the 3545 02:22:33,910 --> 02:22:32,790 all right so 3546 02:22:36,389 --> 02:22:33,920 um 3547 02:22:38,389 --> 02:22:36,399 so the the reference mission that we 3548 02:22:40,469 --> 02:22:38,399 spent most of the time on uh launches 3549 02:22:43,190 --> 02:22:40,479 directly to the lunar gravity assist so 3550 02:22:45,510 --> 02:22:43,200 eliminates that problem entirely um 3551 02:22:47,590 --> 02:22:45,520 there is a wide range of intermediate 3552 02:22:49,510 --> 02:22:47,600 orbits that you could launch to 3553 02:22:50,469 --> 02:22:49,520 including gto and other elliptical 3554 02:22:51,590 --> 02:22:50,479 orbits 3555 02:22:53,270 --> 02:22:51,600 but we haven't spent a lot of time 3556 02:22:55,110 --> 02:22:53,280 looking at the orbital debris problem we 3557 02:22:57,429 --> 02:22:55,120 did spend a little time looking at the 3558 02:23:00,230 --> 02:22:57,439 radiation degradation on the solar rays 3559 02:23:02,790 --> 02:23:00,240 and the need to make them bigger 3560 02:23:03,750 --> 02:23:02,800 to accommodate that but certainly if you 3561 02:23:08,870 --> 02:23:03,760 were 3562 02:23:10,469 --> 02:23:08,880 choice to launch on an elv and spiral 3563 02:23:12,550 --> 02:23:10,479 out from some elliptical earth orbit you 3564 02:23:14,469 --> 02:23:12,560 would definitely have to accommodate or 3565 02:23:16,150 --> 02:23:14,479 make accommodations for that orbital 3566 02:23:18,710 --> 02:23:16,160 debris issue or make sure that you 3567 02:23:20,309 --> 02:23:18,720 understood it 3568 02:23:21,750 --> 02:23:20,319 okay thank you 3569 02:23:23,590 --> 02:23:21,760 for one more 3570 02:23:25,830 --> 02:23:23,600 one more 3571 02:23:28,950 --> 02:23:25,840 i think this this one is for lma i think 3572 02:23:31,110 --> 02:23:28,960 lma mentioned some sort of 3573 02:23:32,790 --> 02:23:31,120 a concept about laser measurements that 3574 02:23:34,790 --> 02:23:32,800 i wasn't familiar with is some 3575 02:23:36,150 --> 02:23:34,800 holographic 3576 02:23:37,590 --> 02:23:36,160 something 3577 02:23:38,790 --> 02:23:37,600 can you explain a little bit more what 3578 02:23:41,830 --> 02:23:38,800 that does 3579 02:23:48,309 --> 02:23:46,230 is it a point cloud or is it 3580 02:23:50,469 --> 02:23:48,319 unfortunately 3581 02:23:53,670 --> 02:23:50,479 no 3582 02:23:55,230 --> 02:23:53,680 it sorry but i can put you in touch with 3583 02:23:58,710 --> 02:23:55,240 somebody 3584 02:24:00,469 --> 02:23:58,720 is it something that is a new concept or 3585 02:24:02,389 --> 02:24:00,479 this is something that it's something 3586 02:24:06,150 --> 02:24:02,399 they've been working working on for 3587 02:24:10,230 --> 02:24:08,150 mostly for terrestrial 3588 02:24:12,630 --> 02:24:10,240 but it's also they've been looking at 3589 02:24:17,030 --> 02:24:15,190 okay all right thank you 3590 02:24:19,190 --> 02:24:17,040 um we come to our last item but it's a 3591 02:24:22,070 --> 02:24:19,200 big item for our last 30 minutes in this 3592 02:24:24,870 --> 02:24:22,080 session um and i just want to um remind 3593 02:24:26,550 --> 02:24:24,880 us uh what the purpose of this wednesday 3594 02:24:29,670 --> 02:24:26,560 session briefing what's what's being 3595 02:24:31,590 --> 02:24:29,680 asked of us um and there were five top 3596 02:24:33,349 --> 02:24:31,600 michelle talked it this morning at the 3597 02:24:35,190 --> 02:24:33,359 plenary but there were five main 3598 02:24:36,870 --> 02:24:35,200 categories that we wanted to we were 3599 02:24:38,870 --> 02:24:36,880 asked to present what our session 3600 02:24:40,710 --> 02:24:38,880 purpose was what our rfi selection 3601 02:24:43,030 --> 02:24:40,720 process and agenda we've talked those 3602 02:24:45,270 --> 02:24:43,040 already in here we'll make slight mods 3603 02:24:47,110 --> 02:24:45,280 to the agenda but we're basically he'll 3604 02:24:49,750 --> 02:24:47,120 um and then key topics discussed and 3605 02:24:51,510 --> 02:24:49,760 findings oh and i forgot to get the 3606 02:24:54,790 --> 02:24:51,520 um 3607 02:24:54,800 --> 02:25:07,110 no 3608 02:25:11,190 --> 02:25:09,030 so we have about four charts that we put 3609 02:25:12,950 --> 02:25:11,200 together a few of us just based on 3610 02:25:14,630 --> 02:25:12,960 having read the rfi's 3611 02:25:16,790 --> 02:25:14,640 just for a starting point for the 3612 02:25:18,389 --> 02:25:16,800 audience because otherwise 40 people 3613 02:25:21,429 --> 02:25:18,399 creating four charts probably doesn't 3614 02:25:23,670 --> 02:25:21,439 work so well but um so the first first 3615 02:25:25,510 --> 02:25:23,680 part of that is and and i should ask add 3616 02:25:27,510 --> 02:25:25,520 a little more the first part of it is 3617 02:25:29,270 --> 02:25:27,520 what key topics did we discuss and then 3618 02:25:31,990 --> 02:25:29,280 what findings 3619 02:25:33,349 --> 02:25:32,000 and uh for findings uh what we're asked 3620 02:25:35,030 --> 02:25:33,359 to provide is a summary of the most 3621 02:25:36,870 --> 02:25:35,040 promising ideas including their 3622 02:25:38,469 --> 02:25:36,880 innovativeness and potential for 3623 02:25:39,990 --> 02:25:38,479 improving mission system performance and 3624 02:25:41,830 --> 02:25:40,000 affordability 3625 02:25:43,429 --> 02:25:41,840 any technology development needed to 3626 02:25:46,950 --> 02:25:43,439 mature the ideas to the point where they 3627 02:25:48,630 --> 02:25:46,960 can be incorporated into system designs 3628 02:25:49,910 --> 02:25:48,640 relationships are linkages between the 3629 02:25:51,830 --> 02:25:49,920 ideas that could help with mission 3630 02:25:53,349 --> 02:25:51,840 system concept integration and further 3631 02:25:54,710 --> 02:25:53,359 studies are next steps and i will admit 3632 02:25:56,150 --> 02:25:54,720 that when we put this together we didn't 3633 02:25:57,590 --> 02:25:56,160 have guidance 3634 02:25:59,110 --> 02:25:57,600 so they probably don't match quite 3635 02:26:01,830 --> 02:25:59,120 exactly 3636 02:26:03,590 --> 02:26:01,840 but we'll go through it and as we'll 3637 02:26:05,910 --> 02:26:03,600 just kind of talk through and and open 3638 02:26:08,550 --> 02:26:05,920 it up for comments as we do the first 3639 02:26:10,550 --> 02:26:08,560 thing we thought we did would do is and 3640 02:26:12,630 --> 02:26:10,560 and again uh you know some of this we 3641 02:26:14,469 --> 02:26:12,640 may be off on how we did it because it 3642 02:26:15,990 --> 02:26:14,479 may not have been quite talked 3643 02:26:17,990 --> 02:26:16,000 as we were going through it but the 3644 02:26:20,309 --> 02:26:18,000 first thing we did is kind of divided 3645 02:26:21,910 --> 02:26:20,319 our topics into these six these five 3646 02:26:23,270 --> 02:26:21,920 categories and then on the next two 3647 02:26:25,110 --> 02:26:23,280 charts we'll talk a little bit more 3648 02:26:27,590 --> 02:26:25,120 detail of each of these five 3649 02:26:30,950 --> 02:26:27,600 um but we kind of we kind of heard a lot 3650 02:26:33,030 --> 02:26:30,960 about uh vehicle systems you know use of 3651 02:26:34,870 --> 02:26:33,040 spacecraft buses that kind of stuff 3652 02:26:37,030 --> 02:26:34,880 there's a large category in sensing 3653 02:26:39,190 --> 02:26:37,040 systems and algorithms 3654 02:26:40,710 --> 02:26:39,200 mission enhancements to the base 3655 02:26:42,950 --> 02:26:40,720 reference mission 3656 02:26:44,630 --> 02:26:42,960 extensibility considerations and 3657 02:26:47,030 --> 02:26:44,640 alternate mission scenarios and concept 3658 02:26:48,230 --> 02:26:47,040 of operations 3659 02:26:50,389 --> 02:26:48,240 we'll go through them next but does 3660 02:26:52,469 --> 02:26:50,399 anybody have any comments at this point 3661 02:26:54,389 --> 02:26:52,479 do they sound about right for the types 3662 02:26:55,110 --> 02:26:54,399 of things we heard it's kind of hard as 3663 02:27:00,950 --> 02:26:55,120 as 3664 02:27:03,030 --> 02:27:00,960 so i i realize how hard that is to do so 3665 02:27:05,270 --> 02:27:03,040 i guess i guess i would comment that i 3666 02:27:07,429 --> 02:27:05,280 heard an awful lot about different 3667 02:27:09,270 --> 02:27:07,439 business strategies you know it's sort 3668 02:27:10,710 --> 02:27:09,280 of i don't know if it fits well with 3669 02:27:13,349 --> 02:27:10,720 everything up there but there were 3670 02:27:14,389 --> 02:27:13,359 different ways of of structuring how we 3671 02:27:16,710 --> 02:27:14,399 do this 3672 02:27:17,750 --> 02:27:16,720 not necessarily the specifics of what we 3673 02:27:20,230 --> 02:27:17,760 do 3674 02:27:22,309 --> 02:27:20,240 right that i i i thought that came 3675 02:27:25,110 --> 02:27:22,319 through in several of the 3676 02:27:26,870 --> 02:27:25,120 items today any any other comments 3677 02:27:30,070 --> 02:27:26,880 that was a good comment 3678 02:27:31,670 --> 02:27:30,080 go ahead john 3679 02:27:34,309 --> 02:27:31,680 yeah i have one comment that seems a 3680 02:27:36,230 --> 02:27:34,319 little counter almost uh the innovation 3681 02:27:37,990 --> 02:27:36,240 and everything else um that we mentioned 3682 02:27:39,990 --> 02:27:38,000 which is there was a theme throughout 3683 02:27:41,990 --> 02:27:40,000 all the presentations which is that for 3684 02:27:43,510 --> 02:27:42,000 most of the areas it seems like there's 3685 02:27:45,030 --> 02:27:43,520 a broad base where we can leverage 3686 02:27:46,309 --> 02:27:45,040 existing assets capabilities and 3687 02:27:47,990 --> 02:27:46,319 expertise 3688 02:27:50,230 --> 02:27:48,000 and then we won't need to 3689 02:27:51,990 --> 02:27:50,240 rely on lots of technology development 3690 02:27:53,349 --> 02:27:52,000 throughout the overall mission in the 3691 02:27:54,309 --> 02:27:53,359 areas where there is a lot of innovation 3692 02:28:01,110 --> 02:27:54,319 you know that's where they'll be looking 3693 02:28:05,190 --> 02:28:03,910 i'm thinking both of those really fit 3694 02:28:08,630 --> 02:28:05,200 under 3695 02:28:10,950 --> 02:28:08,640 most promising ideas that 3696 02:28:11,830 --> 02:28:10,960 help to reduce 3697 02:28:14,469 --> 02:28:11,840 um 3698 02:28:17,270 --> 02:28:14,479 improve system performance 3699 02:28:19,429 --> 02:28:17,280 and um contribute to affordability both 3700 02:28:22,150 --> 02:28:19,439 of them could show up under that first 3701 02:28:23,830 --> 02:28:22,160 bullet couldn't they 3702 02:28:25,590 --> 02:28:23,840 and and what first quality are you 3703 02:28:27,830 --> 02:28:25,600 talking about the first bulletin 3704 02:28:30,950 --> 02:28:27,840 findings is this turned on can anyone 3705 02:28:30,960 --> 02:28:33,349 okay 3706 02:28:38,309 --> 02:28:36,309 all right any other comments 3707 02:28:41,910 --> 02:28:38,319 all right let's step through 3708 02:28:47,110 --> 02:28:45,110 on in vehicle systems 3709 02:28:48,309 --> 02:28:47,120 we had discussions on key technology 3710 02:28:50,790 --> 02:28:48,319 readiness 3711 02:28:53,670 --> 02:28:50,800 areas solar arrays thrusters power 3712 02:28:56,710 --> 02:28:53,680 processing units 3713 02:28:58,550 --> 02:28:56,720 adaptations of existing spacecraft buses 3714 02:29:00,309 --> 02:28:58,560 uh the balance i don't think i heard 3715 02:29:02,550 --> 02:29:00,319 this so much as we saw in the papers we 3716 02:29:04,230 --> 02:29:02,560 thought but we can talk about whether we 3717 02:29:05,670 --> 02:29:04,240 felt like we did a balance between 3718 02:29:07,830 --> 02:29:05,680 technology development for improved 3719 02:29:09,830 --> 02:29:07,840 mission versus you oh no this one we 3720 02:29:11,270 --> 02:29:09,840 certainly did use of low risk mature 3721 02:29:13,349 --> 02:29:11,280 technologies that was the kind of the 3722 02:29:15,190 --> 02:29:13,359 comment that that john made what i 3723 02:29:15,990 --> 02:29:15,200 didn't hear necessarily was a talk about 3724 02:29:22,710 --> 02:29:16,000 a 3725 02:29:24,790 --> 02:29:22,720 something in them 3726 02:29:26,309 --> 02:29:24,800 and then off uh have alpha amps um 3727 02:29:28,469 --> 02:29:26,319 certainly the plan we have right now is 3728 02:29:31,030 --> 02:29:28,479 to pick some medium level and off-ramp 3729 02:29:32,469 --> 02:29:31,040 if it need be 3730 02:29:34,950 --> 02:29:32,479 as opposed to trying to unramp it 3731 02:29:36,469 --> 02:29:34,960 especially if our target schedule is 3732 02:29:37,349 --> 02:29:36,479 what it is so 3733 02:29:39,190 --> 02:29:37,359 and then 3734 02:29:41,429 --> 02:29:39,200 key risk and development areas 3735 02:29:43,830 --> 02:29:41,439 uh asteroid characterization rendezvous 3736 02:29:46,230 --> 02:29:43,840 and capture system solar arrays high 3737 02:29:47,270 --> 02:29:46,240 power thrusters power processing units 3738 02:29:48,710 --> 02:29:47,280 although 3739 02:29:50,070 --> 02:29:48,720 really we hear talks about that being 3740 02:29:51,830 --> 02:29:50,080 fairly mature so maybe that shouldn't be 3741 02:29:54,710 --> 02:29:51,840 on this list but we can talk about it 3742 02:29:56,389 --> 02:29:54,720 xenon tanks dust and volatiles 3743 02:29:58,150 --> 02:29:56,399 so i'll stop there and just kind of open 3744 02:30:00,150 --> 02:29:58,160 up the discussions on does this 3745 02:30:05,750 --> 02:30:00,160 adequately capture things and and are 3746 02:30:09,910 --> 02:30:07,590 yeah the one thing i think that probably 3747 02:30:12,150 --> 02:30:09,920 needs to be added to that that i heard 3748 02:30:16,550 --> 02:30:12,160 in a number of the presentations is that 3749 02:30:16,560 --> 02:30:19,910 capability for simulation 3750 02:30:24,790 --> 02:30:22,550 and test of many of these systems on the 3751 02:30:26,150 --> 02:30:24,800 ground and lab 3752 02:30:33,910 --> 02:30:26,160 so i think they didn't need to capture 3753 02:30:38,150 --> 02:30:35,190 we'll see if we have that somewhere 3754 02:30:41,990 --> 02:30:38,160 coming up i don't think we do though 3755 02:30:46,790 --> 02:30:44,630 yeah ppus i think we take off 3756 02:30:48,309 --> 02:30:46,800 there was discussion xenon tanks but 3757 02:30:50,710 --> 02:30:48,319 it's really a go design not really a 3758 02:30:51,830 --> 02:30:50,720 technology or a key risk area does 3759 02:30:54,309 --> 02:30:51,840 anybody 3760 02:30:58,230 --> 02:30:56,309 there's still some out there that think 3761 02:31:00,950 --> 02:30:58,240 that we should leave the power 3762 02:31:03,030 --> 02:31:00,960 processing units i think 3763 02:31:05,110 --> 02:31:03,040 okay what it's worth um 3764 02:31:07,429 --> 02:31:05,120 there was at least 3765 02:31:09,510 --> 02:31:07,439 the european talk talked about something 3766 02:31:11,990 --> 02:31:09,520 other than hall thrusters 3767 02:31:12,790 --> 02:31:12,000 and we've seen that a couple of times 3768 02:31:16,950 --> 02:31:12,800 where 3769 02:31:19,429 --> 02:31:16,960 the discussion was uh can we do you know 3770 02:31:20,550 --> 02:31:19,439 other plasma based 3771 02:31:22,309 --> 02:31:20,560 sep 3772 02:31:25,429 --> 02:31:22,319 i think we're we're going to run into a 3773 02:31:27,349 --> 02:31:25,439 technology timeline difficulty with that 3774 02:31:30,389 --> 02:31:27,359 but it was definitely brought up as a 3775 02:31:31,990 --> 02:31:30,399 discussion point that's true um and 3776 02:31:34,309 --> 02:31:32,000 and it has some very interesting 3777 02:31:36,469 --> 02:31:34,319 features but as you said and as they 3778 02:31:37,510 --> 02:31:36,479 pointed out the trl is still 3779 02:31:38,870 --> 02:31:37,520 something that 3780 02:31:40,630 --> 02:31:38,880 makes it challenging but but it's a good 3781 02:31:41,510 --> 02:31:40,640 thing to bring out 3782 02:31:43,510 --> 02:31:41,520 um 3783 02:31:50,309 --> 02:31:43,520 anything else 3784 02:31:58,469 --> 02:31:52,150 would you go to a mic please 3785 02:32:01,910 --> 02:32:00,309 i think one of the key things in the 3786 02:32:03,830 --> 02:32:01,920 vehicle in the sensing systems is we're 3787 02:32:06,230 --> 02:32:03,840 not exactly sure what we're going to go 3788 02:32:09,190 --> 02:32:06,240 and find even if there are precursor 3789 02:32:11,030 --> 02:32:09,200 missions so i think one of the key 3790 02:32:12,870 --> 02:32:11,040 design requirements is that you know 3791 02:32:15,190 --> 02:32:12,880 either the vehicle system or the sensing 3792 02:32:16,950 --> 02:32:15,200 system needs to be very flexible 3793 02:32:17,670 --> 02:32:16,960 to be able to accommodate a large number 3794 02:32:19,429 --> 02:32:17,680 of 3795 02:32:21,590 --> 02:32:19,439 surfaces or other pieces that we're 3796 02:32:23,510 --> 02:32:21,600 going to encounter there 3797 02:32:24,550 --> 02:32:23,520 i think that was one of the key unknowns 3798 02:32:26,550 --> 02:32:24,560 we saw throughout everyone's 3799 02:32:27,990 --> 02:32:26,560 presentation was 3800 02:32:29,830 --> 02:32:28,000 you know how do i 3801 02:32:36,950 --> 02:32:29,840 know what i'm designing for or do i 3802 02:32:42,230 --> 02:32:39,270 one other thing jim yeah i don't know if 3803 02:32:44,550 --> 02:32:42,240 it fits here under vehicle systems or 3804 02:32:46,469 --> 02:32:44,560 someplace else but you know there was 3805 02:32:48,870 --> 02:32:46,479 there's still a lot of open discussion 3806 02:32:50,710 --> 02:32:48,880 about the type of capture mechanism 3807 02:32:51,990 --> 02:32:50,720 whether you're going to go grab regolith 3808 02:32:53,750 --> 02:32:52,000 or whether you're going to pick off a 3809 02:32:55,750 --> 02:32:53,760 rock or whether you're going to grab the 3810 02:32:58,630 --> 02:32:55,760 whole thing and if you are how does that 3811 02:33:00,389 --> 02:32:58,640 work with the dynamics it's not part of 3812 02:33:02,630 --> 02:33:00,399 the sensing system and algorithms and 3813 02:33:04,230 --> 02:33:02,640 it's not part of 3814 02:33:06,070 --> 02:33:04,240 so it could be under vehicle systems 3815 02:33:08,469 --> 02:33:06,080 unless you want to bucket that i think 3816 02:33:10,309 --> 02:33:08,479 we bucketed it under alternate missions 3817 02:33:13,110 --> 02:33:10,319 okay concept of operation 3818 02:33:14,630 --> 02:33:13,120 but but i think a subset of that is just 3819 02:33:16,230 --> 02:33:14,640 how you're going to actually grab 3820 02:33:18,790 --> 02:33:16,240 whatever it is oh yeah that's true 3821 02:33:20,630 --> 02:33:18,800 that's true and actually with that 3822 02:33:22,710 --> 02:33:20,640 there's also there's a lot of discussion 3823 02:33:24,790 --> 02:33:22,720 about precursors i don't know if it goes 3824 02:33:27,110 --> 02:33:24,800 there or alternative missions but it 3825 02:33:29,270 --> 02:33:27,120 seemed um that was a 3826 02:33:30,870 --> 02:33:29,280 yeah let's let's not lose that thought 3827 02:33:32,870 --> 02:33:30,880 um and see if we get there when we get 3828 02:33:33,590 --> 02:33:32,880 to those i think we do but but i'm not 3829 02:33:34,550 --> 02:33:33,600 sure 3830 02:33:36,790 --> 02:33:34,560 um 3831 02:33:39,349 --> 02:33:36,800 especially on the capture system but for 3832 02:33:41,750 --> 02:33:39,359 all vehicle systems being able to vnv it 3833 02:33:44,150 --> 02:33:41,760 on the ground is incredibly important 3834 02:33:45,590 --> 02:33:44,160 and the capture system the whole 3835 02:33:48,309 --> 02:33:45,600 driving 3836 02:33:50,230 --> 02:33:48,319 you know philosophy underlying the the 3837 02:33:52,469 --> 02:33:50,240 reference capture system is the ability 3838 02:33:54,630 --> 02:33:52,479 to vnv it on the ground that's the 3839 02:33:56,150 --> 02:33:54,640 overriding concern okay 3840 02:33:58,230 --> 02:33:56,160 jim one other input too and i don't know 3841 02:33:59,990 --> 02:33:58,240 if it goes here or if you've got it on 3842 02:34:01,990 --> 02:34:00,000 vehicle systems if the the concept of 3843 02:34:03,030 --> 02:34:02,000 designing for reusability extensibility 3844 02:34:04,950 --> 02:34:03,040 long life 3845 02:34:06,710 --> 02:34:04,960 that i don't know we have a you got a 3846 02:34:08,550 --> 02:34:06,720 sensibility category okay man that's 3847 02:34:10,309 --> 02:34:08,560 working um and make sure when we get to 3848 02:34:11,750 --> 02:34:10,319 that uh if we haven't captured it 3849 02:34:13,429 --> 02:34:11,760 adequately 3850 02:34:15,670 --> 02:34:13,439 okay anything else 3851 02:34:19,429 --> 02:34:15,680 go ahead 3852 02:34:26,070 --> 02:34:22,389 two or three uh different presenters 3853 02:34:27,429 --> 02:34:26,080 talked about using microsats as a 3854 02:34:30,389 --> 02:34:27,439 probe 3855 02:34:33,349 --> 02:34:30,399 is that under sensing or 3856 02:34:35,110 --> 02:34:33,359 is that somewhere else because they 3857 02:34:36,230 --> 02:34:35,120 really referred them as 3858 02:34:39,110 --> 02:34:36,240 sensors 3859 02:34:40,230 --> 02:34:39,120 to know more about the target 3860 02:34:42,070 --> 02:34:40,240 uh 3861 02:34:43,510 --> 02:34:42,080 we had thought that like cubesats and 3862 02:34:47,590 --> 02:34:43,520 stuff we were putting it under mission 3863 02:34:50,150 --> 02:34:48,790 anything else and we'll go on to the 3864 02:34:52,710 --> 02:34:50,160 next category 3865 02:34:54,150 --> 02:34:52,720 sensing systems and algorithms 3866 02:34:55,750 --> 02:34:54,160 there's a wide range of sensor 3867 02:34:57,270 --> 02:34:55,760 technologies discussed for various 3868 02:34:58,790 --> 02:34:57,280 mission requirements 3869 02:35:02,630 --> 02:34:58,800 which includes characterization 3870 02:35:03,910 --> 02:35:02,640 rendezvous proximity operations capture 3871 02:35:06,550 --> 02:35:03,920 you know things to think about the 3872 02:35:08,550 --> 02:35:06,560 target size shape range temple dynamics 3873 02:35:10,469 --> 02:35:08,560 shape modeling 3874 02:35:13,110 --> 02:35:10,479 closed loop control with uncooperative 3875 02:35:14,309 --> 02:35:13,120 target tracking relative nav rate 3876 02:35:15,990 --> 02:35:14,319 matching 3877 02:35:17,990 --> 02:35:16,000 considerations for surface and 3878 02:35:20,710 --> 02:35:18,000 subsurface characterization 3879 02:35:22,710 --> 02:35:20,720 uh crater detection tracking asteroid 3880 02:35:25,750 --> 02:35:22,720 structural strength you know depending 3881 02:35:27,910 --> 02:35:25,760 on your your your mission scenario 3882 02:35:30,070 --> 02:35:27,920 sensor technologies include visible ir 3883 02:35:34,070 --> 02:35:30,080 camera lidar laser altimeter 3884 02:35:36,150 --> 02:35:34,080 spectrometry radar tomography and so on 3885 02:35:38,230 --> 02:35:36,160 we had discussions of integrated systems 3886 02:35:39,910 --> 02:35:38,240 and algorithm development and a lot of 3887 02:35:41,990 --> 02:35:39,920 hardware and software adaptation from 3888 02:35:49,030 --> 02:35:42,000 heritage systems and we listed a bunch 3889 02:35:49,040 --> 02:35:53,429 tell the section that heather 3890 02:35:53,439 --> 02:35:59,110 okay we'll go on 3891 02:36:04,150 --> 02:36:01,670 um then the other topic areas that we 3892 02:36:05,830 --> 02:36:04,160 had and then we need to try to think 3893 02:36:08,230 --> 02:36:05,840 about the different business strategies 3894 02:36:10,870 --> 02:36:08,240 one as well but mission enhancements uh 3895 02:36:13,590 --> 02:36:10,880 what we put under there uh was robotic 3896 02:36:15,670 --> 02:36:13,600 manipulators for enhanced asteroid 3897 02:36:17,910 --> 02:36:15,680 characterization dissimilar capture 3898 02:36:19,190 --> 02:36:17,920 techniques or an enabler for pick up a 3899 02:36:21,270 --> 02:36:19,200 rock scenario 3900 02:36:23,110 --> 02:36:21,280 a cubesat class observation and sensor 3901 02:36:26,070 --> 02:36:23,120 spacecraft 3902 02:36:28,150 --> 02:36:26,080 contact excursion probe surface samplers 3903 02:36:29,990 --> 02:36:28,160 and i'm not sure it really kind of got 3904 02:36:31,590 --> 02:36:30,000 talked about here but taking advantage 3905 02:36:34,389 --> 02:36:31,600 of about the three year transition to 3906 02:36:41,830 --> 02:36:34,399 cis lunar space to do further 3907 02:36:45,830 --> 02:36:43,670 okay that's pretty good 3908 02:36:47,830 --> 02:36:45,840 um 3909 02:36:48,710 --> 02:36:47,840 what's that 3910 02:36:50,389 --> 02:36:48,720 yeah 3911 02:36:52,710 --> 02:36:50,399 when you wear everybody out it's easier 3912 02:36:54,469 --> 02:36:52,720 to get through these sort of things 3913 02:36:56,710 --> 02:36:54,479 thank you for all the presenters 3914 02:36:58,389 --> 02:36:56,720 we really want to make sure that we 3915 02:37:00,790 --> 02:36:58,399 captured the mission enhancements that 3916 02:37:04,469 --> 02:37:00,800 were in the paper right so 3917 02:37:06,710 --> 02:37:04,479 if you don't see what you told us 3918 02:37:09,110 --> 02:37:06,720 but we'll go on um and and as need be 3919 02:37:10,710 --> 02:37:09,120 you know you you can contact me uh us 3920 02:37:12,630 --> 02:37:10,720 over the next day or two 3921 02:37:15,349 --> 02:37:12,640 as well as as we finalize this 3922 02:37:16,950 --> 02:37:15,359 extensibility was our next major topic 3923 02:37:18,870 --> 02:37:16,960 we talked about the similarity and needs 3924 02:37:21,110 --> 02:37:18,880 of satellite servicing missions 3925 02:37:23,110 --> 02:37:21,120 potential for commercial applications 3926 02:37:25,510 --> 02:37:23,120 potential reuse as a cargo tug for 3927 02:37:27,510 --> 02:37:25,520 translunar assets planetary defense 3928 02:37:29,349 --> 02:37:27,520 asteroid deflection demonstration space 3929 02:37:31,110 --> 02:37:29,359 debris removal i'm not sure everything 3930 02:37:33,190 --> 02:37:31,120 actually got talked here today as we as 3931 02:37:34,710 --> 02:37:33,200 much as we saw in some of the papers but 3932 02:37:36,309 --> 02:37:34,720 any comments to this section can you 3933 02:37:37,910 --> 02:37:36,319 list some examples of the potential 3934 02:37:39,990 --> 02:37:37,920 commercial applications so we don't lose 3935 02:37:42,309 --> 02:37:40,000 those thoughts um that's a good idea you 3936 02:37:43,910 --> 02:37:42,319 want to um 3937 02:37:46,790 --> 02:37:43,920 isru 3938 02:37:51,670 --> 02:37:46,800 yeah and then the fuel for satellites 3939 02:37:55,750 --> 02:37:54,230 well the maturation of the scp helps 3940 02:37:58,630 --> 02:37:55,760 geo-converge right 3941 02:38:00,469 --> 02:37:58,640 whether it's ppu quad junction cells 3942 02:38:02,469 --> 02:38:00,479 better deployables 3943 02:38:10,389 --> 02:38:02,479 the list goes on spin off and i don't 3944 02:38:10,399 --> 02:38:13,510 is it worth mentioning 3945 02:38:17,349 --> 02:38:16,309 the robotic planetary 3946 02:38:21,190 --> 02:38:17,359 there is an extensibility they're 3947 02:38:27,270 --> 02:38:23,510 robotic science mission 3948 02:38:30,070 --> 02:38:28,389 okay 3949 02:38:33,510 --> 02:38:30,080 uh i don't i didn't see it here but 3950 02:38:35,910 --> 02:38:33,520 under also under extensibility you know 3951 02:38:36,950 --> 02:38:35,920 if there are assets that are brought 3952 02:38:39,270 --> 02:38:36,960 back 3953 02:38:41,590 --> 02:38:39,280 um you know it's not just 3954 02:38:44,550 --> 02:38:41,600 human crude missions from 3955 02:38:46,389 --> 02:38:44,560 nasa that could go there you know other 3956 02:38:48,389 --> 02:38:46,399 nations could go there 3957 02:38:50,389 --> 02:38:48,399 um you know there are 3958 02:38:52,710 --> 02:38:50,399 you know industry could go there 3959 02:38:54,870 --> 02:38:52,720 in other words there's a 3960 02:38:56,870 --> 02:38:54,880 there's clearly some interest in 3961 02:38:58,710 --> 02:38:56,880 expanding the scope of what you do with 3962 02:39:00,309 --> 02:38:58,720 the results 3963 02:39:03,190 --> 02:39:00,319 okay 3964 02:39:05,190 --> 02:39:03,200 and there's also the trade space of do 3965 02:39:07,590 --> 02:39:05,200 you make this modular 3966 02:39:10,630 --> 02:39:07,600 which affects the extendability 3967 02:39:14,790 --> 02:39:10,640 or do you make it one piece and just 3968 02:39:17,590 --> 02:39:14,800 duplicate that for another mission later 3969 02:39:18,950 --> 02:39:17,600 yes did we well we tried to capture that 3970 02:39:20,469 --> 02:39:18,960 in alternate mission scenarios or 3971 02:39:21,510 --> 02:39:20,479 concept really under concept of 3972 02:39:23,910 --> 02:39:21,520 operations 3973 02:39:25,349 --> 02:39:23,920 the last does that get at your point but 3974 02:39:29,349 --> 02:39:25,359 you didn't really say anything about 3975 02:39:34,550 --> 02:39:31,429 do you think it works okay as a concept 3976 02:39:38,469 --> 02:39:34,560 of operations if we add you know into it 3977 02:39:39,349 --> 02:39:38,479 it touched on testing it it tests 3978 02:39:42,309 --> 02:39:39,359 on 3979 02:39:44,150 --> 02:39:42,319 extendability lots of places okay 3980 02:39:47,670 --> 02:39:44,160 all right 3981 02:39:49,030 --> 02:39:47,680 extending on uh the sap comment earlier 3982 02:39:51,110 --> 02:39:49,040 uh you know 3983 02:39:52,950 --> 02:39:51,120 the sap that we're 3984 02:39:55,110 --> 02:39:52,960 trying to push here does an awful lot 3985 02:39:58,710 --> 02:39:55,120 not just for 3986 02:40:01,670 --> 02:39:58,720 advancing the cause for geocom birds but 3987 02:40:04,710 --> 02:40:01,680 for doing things like deep space 3988 02:40:06,550 --> 02:40:04,720 space orbital debris 3989 02:40:09,110 --> 02:40:06,560 satellite servicing 3990 02:40:10,630 --> 02:40:09,120 uh human exploration you know deep space 3991 02:40:13,750 --> 02:40:10,640 human exploration i mean that was one of 3992 02:40:15,349 --> 02:40:13,760 our initial motivations for sdmd doing 3993 02:40:16,630 --> 02:40:15,359 these technology advancements in the 3994 02:40:18,230 --> 02:40:16,640 first place and 3995 02:40:20,710 --> 02:40:18,240 i think we got to make sure we captured 3996 02:40:21,990 --> 02:40:20,720 that yes some of those i felt i thought 3997 02:40:23,990 --> 02:40:22,000 that we were trying to capture with 3998 02:40:26,309 --> 02:40:24,000 these yeah but you kind of you don't i i 3999 02:40:27,830 --> 02:40:26,319 guess what i would do is put under 4000 02:40:31,190 --> 02:40:27,840 extensibility 4001 02:40:33,110 --> 02:40:31,200 scp specific ah okay spell out sap 4002 02:40:34,870 --> 02:40:33,120 specifically yeah okay and because a lot 4003 02:40:36,870 --> 02:40:34,880 of these are connected to us right but 4004 02:40:40,870 --> 02:40:36,880 you're not making the point yep i got it 4005 02:40:44,389 --> 02:40:42,469 well i guess if we're going to talk 4006 02:40:46,469 --> 02:40:44,399 about about that those sorts of 4007 02:40:49,269 --> 02:40:46,479 specifics right if we develop advanced 4008 02:40:50,870 --> 02:40:49,279 robotics for this those robotics 4009 02:40:52,630 --> 02:40:50,880 with humans involved and work in 4010 02:40:55,510 --> 02:40:52,640 conjunction with dba 4011 02:40:59,349 --> 02:40:55,520 right assembly of large observatories 4012 02:41:02,790 --> 02:40:59,359 um assembly of a mars excursion vehicle 4013 02:41:06,309 --> 02:41:04,550 the expansion of humans into the solar 4014 02:41:09,110 --> 02:41:06,319 system with robotics and humans working 4015 02:41:12,230 --> 02:41:10,309 okay 4016 02:41:13,750 --> 02:41:12,240 all right just because when most people 4017 02:41:15,429 --> 02:41:13,760 see satellite servicing they think 4018 02:41:17,910 --> 02:41:15,439 fixing things that are already existing 4019 02:41:20,230 --> 02:41:17,920 there as opposed to building new things 4020 02:41:21,510 --> 02:41:20,240 that can't be built without it 4021 02:41:24,710 --> 02:41:21,520 okay 4022 02:41:30,230 --> 02:41:26,790 james mentioned that the leftover 4023 02:41:31,830 --> 02:41:30,240 material would have value to industry it 4024 02:41:34,230 --> 02:41:31,840 would have much more value to industry 4025 02:41:35,670 --> 02:41:34,240 if it had some say in which rock was 4026 02:41:37,830 --> 02:41:35,680 brought back 4027 02:41:39,590 --> 02:41:37,840 the any rock will do approach 4028 02:41:43,269 --> 02:41:39,600 doesn't guarantee you really that you'll 4029 02:41:44,790 --> 02:41:43,279 have an industrial useful resource 4030 02:41:47,429 --> 02:41:44,800 left over after the 4031 02:41:49,510 --> 02:41:47,439 orion mission okay 4032 02:41:50,870 --> 02:41:49,520 there was a point made earlier that you 4033 02:41:52,550 --> 02:41:50,880 know big rocks are easier to find than 4034 02:41:53,590 --> 02:41:52,560 small rocks 4035 02:41:55,429 --> 02:41:53,600 and that's of course because of the 4036 02:41:56,790 --> 02:41:55,439 inverse square law but what wasn't 4037 02:41:59,269 --> 02:41:56,800 mentioned is that the slope of the 4038 02:42:01,030 --> 02:41:59,279 population curve is minus 2.6 and 4039 02:42:03,670 --> 02:42:01,040 therefore you actually find much more 4040 02:42:05,110 --> 02:42:03,680 small objects than large objects and 4041 02:42:07,510 --> 02:42:05,120 furthermore because of the fourth power 4042 02:42:09,750 --> 02:42:07,520 radar law they're much much more likely 4043 02:42:12,550 --> 02:42:09,760 to be in the radar you know within range 4044 02:42:14,550 --> 02:42:12,560 of our radar systems are sibo and 4045 02:42:16,469 --> 02:42:14,560 goldstone and so 4046 02:42:18,870 --> 02:42:16,479 if you go out just looking for these 4047 02:42:21,110 --> 02:42:18,880 objects you're they're overwhelmingly 4048 02:42:22,469 --> 02:42:21,120 going to find the smaller objects and 4049 02:42:24,870 --> 02:42:22,479 you're going to be able to characterize 4050 02:42:27,269 --> 02:42:24,880 the smaller objects preferentially to 4051 02:42:28,550 --> 02:42:27,279 the larger objects 4052 02:42:30,469 --> 02:42:28,560 okay 4053 02:42:32,790 --> 02:42:30,479 i'm not sure yet how to capture that in 4054 02:42:34,070 --> 02:42:32,800 this thought process but but we'll make 4055 02:42:36,389 --> 02:42:34,080 a note 4056 02:42:39,190 --> 02:42:36,399 okay that would be very helpful 4057 02:42:40,630 --> 02:42:39,200 all right oh just one i guess we didn't 4058 02:42:43,030 --> 02:42:40,640 it was only talked about briefly but in 4059 02:42:44,469 --> 02:42:43,040 terms of extensibility um you have a lot 4060 02:42:46,230 --> 02:42:44,479 of capability up here but you don't talk 4061 02:42:48,070 --> 02:42:46,240 at all about any science capability you 4062 02:42:49,670 --> 02:42:48,080 could imagine using this uh in some 4063 02:42:51,269 --> 02:42:49,680 fashion to do something really 4064 02:42:53,269 --> 02:42:51,279 interesting in terms of bringing a 4065 02:42:55,910 --> 02:42:53,279 telescope to l1 or l2 or something like 4066 02:42:57,590 --> 02:42:55,920 that you could there's a science 4067 02:42:59,190 --> 02:42:57,600 potential here oh that i think you're 4068 02:43:00,870 --> 02:42:59,200 not capturing with developing this kind 4069 02:43:02,309 --> 02:43:00,880 of technology yeah if you want to if you 4070 02:43:03,750 --> 02:43:02,319 want to move something very big to an 4071 02:43:05,349 --> 02:43:03,760 interesting place you have a possibility 4072 02:43:06,790 --> 02:43:05,359 of doing that oh okay so it comes back 4073 02:43:07,990 --> 02:43:06,800 to the like the accept question 4074 02:43:09,830 --> 02:43:08,000 especially 4075 02:43:12,070 --> 02:43:09,840 and it's not just for these sort of 4076 02:43:13,910 --> 02:43:12,080 things but even as a science potential 4077 02:43:15,190 --> 02:43:13,920 for moving things around 4078 02:43:16,950 --> 02:43:15,200 yeah i mean i i don't know what that 4079 02:43:18,550 --> 02:43:16,960 would be but you know we could be 4080 02:43:20,550 --> 02:43:18,560 ambitious right so 4081 02:43:22,950 --> 02:43:20,560 okay thank you anything else in this 4082 02:43:24,469 --> 02:43:22,960 category oh yeah so i have sort of a 4083 02:43:27,349 --> 02:43:24,479 more general question i'm wondering if 4084 02:43:28,790 --> 02:43:27,359 it's within the scope of this uh uh 4085 02:43:30,469 --> 02:43:28,800 summary to try and place some 4086 02:43:32,309 --> 02:43:30,479 prioritization 4087 02:43:33,990 --> 02:43:32,319 on this long list 4088 02:43:36,550 --> 02:43:34,000 that has consensus of this group or 4089 02:43:38,710 --> 02:43:36,560 whether we're just trying to report on 4090 02:43:40,550 --> 02:43:38,720 everything that was covered i'm not sure 4091 02:43:43,110 --> 02:43:40,560 if that is beyond what we're supposed to 4092 02:43:45,429 --> 02:43:43,120 do my guess is is we probably won't get 4093 02:43:47,349 --> 02:43:45,439 there in the next 15 minutes 4094 02:43:48,710 --> 02:43:47,359 um you know it's a good thought and 4095 02:43:50,230 --> 02:43:48,720 maybe what we can do in terms of the 4096 02:43:51,510 --> 02:43:50,240 findings is one of the things you do is 4097 02:43:53,269 --> 02:43:51,520 you take this list and start going 4098 02:43:55,269 --> 02:43:53,279 through a prioritization activity that 4099 02:43:57,349 --> 02:43:55,279 might be the how we can fit it in as as 4100 02:43:59,110 --> 02:43:57,359 part of our you know next steps that 4101 02:44:01,349 --> 02:43:59,120 kind of stuff is we've got a lot of good 4102 02:44:02,230 --> 02:44:01,359 ideas but but one of the next steps is 4103 02:44:03,670 --> 02:44:02,240 to 4104 02:44:05,750 --> 02:44:03,680 sort out which ones 4105 02:44:07,429 --> 02:44:05,760 hey jim yeah i think the way that we 4106 02:44:08,950 --> 02:44:07,439 should handle that i mean i don't 4107 02:44:11,110 --> 02:44:08,960 disagree with it at all i think we need 4108 02:44:13,030 --> 02:44:11,120 to yeah think about that but i think 4109 02:44:15,429 --> 02:44:13,040 that that should be a discussion that we 4110 02:44:19,190 --> 02:44:15,439 have with the wider group sort of the on 4111 02:44:21,750 --> 02:44:19,200 the on wednesday we're all still here um 4112 02:44:23,670 --> 02:44:21,760 that that we could all say well where's 4113 02:44:25,190 --> 02:44:23,680 what is the next step moving forward i 4114 02:44:26,950 --> 02:44:25,200 mean we're not going to just take all 4115 02:44:28,790 --> 02:44:26,960 this data and then send everybody away 4116 02:44:30,550 --> 02:44:28,800 and say okay we're done right i mean 4117 02:44:33,269 --> 02:44:30,560 nasa is going to definitely interact 4118 02:44:35,990 --> 02:44:33,279 with the participants here going forward 4119 02:44:37,429 --> 02:44:36,000 and but we need to establish you know 4120 02:44:38,630 --> 02:44:37,439 what we should do and how we should do 4121 02:44:40,070 --> 02:44:38,640 it and i think that's something that we 4122 02:44:41,110 --> 02:44:40,080 should bring up as a topic for 4123 02:44:42,630 --> 02:44:41,120 discussion 4124 02:44:44,389 --> 02:44:42,640 uh with the 4125 02:44:45,510 --> 02:44:44,399 the broader audience you know we had 4126 02:44:49,190 --> 02:44:45,520 some other 4127 02:44:51,590 --> 02:44:49,200 uh panels that broke off here uh as you 4128 02:44:54,309 --> 02:44:51,600 know apart from us here today 4129 02:44:56,469 --> 02:44:54,319 uh in the parallel sessions and i'm sure 4130 02:44:57,830 --> 02:44:56,479 they brought up the same point yeah okay 4131 02:45:00,790 --> 02:44:57,840 that's a good point 4132 02:45:02,070 --> 02:45:00,800 we'll figure out how to do that 4133 02:45:04,630 --> 02:45:02,080 so we go on to alternate mission 4134 02:45:06,710 --> 02:45:04,640 scenarios concept of operations we kind 4135 02:45:08,790 --> 02:45:06,720 of had the the 4136 02:45:10,950 --> 02:45:08,800 various you know got introduced very 4137 02:45:12,070 --> 02:45:10,960 quickly on to some of the options that 4138 02:45:13,830 --> 02:45:12,080 were out there 4139 02:45:16,550 --> 02:45:13,840 uh the benefits of obtaining multiple 4140 02:45:19,510 --> 02:45:16,560 samples from the robopile asteroid many 4141 02:45:21,590 --> 02:45:19,520 moons um good discussion on many moons 4142 02:45:23,269 --> 02:45:21,600 and the alternatives there and in terms 4143 02:45:25,670 --> 02:45:23,279 of concept of operation a separate 4144 02:45:28,389 --> 02:45:25,680 transporter and capture vehicles 4145 02:45:30,870 --> 02:45:28,399 and trying to factor in modularity um 4146 02:45:33,510 --> 02:45:30,880 comments on this section so as brought 4147 02:45:37,349 --> 02:45:33,520 up earlier the big one is do we do 4148 02:45:38,870 --> 02:45:37,359 precursors or cursors yes right 4149 02:45:40,790 --> 02:45:38,880 or do you 4150 02:45:42,790 --> 02:45:40,800 you know sort of a modification to that 4151 02:45:45,590 --> 02:45:42,800 is do you do a campaign where you go to 4152 02:45:48,309 --> 02:45:45,600 more than one asteroid you know a small 4153 02:45:49,750 --> 02:45:48,319 one and a big one or some combination 4154 02:45:51,110 --> 02:45:49,760 thereof 4155 02:45:52,469 --> 02:45:51,120 um 4156 02:45:54,710 --> 02:45:52,479 okay 4157 02:45:57,750 --> 02:45:54,720 or do you or do you 4158 02:46:00,870 --> 02:45:57,760 use your combination of assets to do 4159 02:46:02,630 --> 02:46:00,880 grab you know a combination of you know 4160 02:46:04,630 --> 02:46:02,640 regolith and 4161 02:46:06,550 --> 02:46:04,640 there's there's a whole 4162 02:46:07,750 --> 02:46:06,560 different approach 4163 02:46:10,790 --> 02:46:07,760 okay 4164 02:46:12,950 --> 02:46:10,800 i'll expand on that one uh so originally 4165 02:46:14,950 --> 02:46:12,960 when john did the first the kick study 4166 02:46:16,230 --> 02:46:14,960 there was a longer period between launch 4167 02:46:18,150 --> 02:46:16,240 and retrieving they had a little more 4168 02:46:20,389 --> 02:46:18,160 time which opened up more targets and 4169 02:46:22,630 --> 02:46:20,399 things like that uh then when we brought 4170 02:46:25,190 --> 02:46:22,640 it into nasa we focused on you know 4171 02:46:26,550 --> 02:46:25,200 meeting certain milestones uh doing it 4172 02:46:28,389 --> 02:46:26,560 all ourselves without working with 4173 02:46:30,070 --> 02:46:28,399 industry to fund it so you know if you 4174 02:46:31,269 --> 02:46:30,080 have these industry partnerships that 4175 02:46:33,190 --> 02:46:31,279 we're talking about where maybe they 4176 02:46:35,750 --> 02:46:33,200 would fund a precursor 4177 02:46:38,710 --> 02:46:35,760 and maybe our particular 4178 02:46:39,990 --> 02:46:38,720 return date wouldn't be 2023 or 2024 it 4179 02:46:41,510 --> 02:46:40,000 might be a little bit out it might open 4180 02:46:43,269 --> 02:46:41,520 up a greater opportunity to leverage 4181 02:46:45,110 --> 02:46:43,279 what james just said do we have a better 4182 02:46:46,550 --> 02:46:45,120 campaign perspective can we partner with 4183 02:46:47,269 --> 02:46:46,560 industry to make this better for all of 4184 02:46:50,790 --> 02:46:47,279 us 4185 02:46:50,800 --> 02:46:55,349 yes yes 4186 02:46:58,870 --> 02:46:57,349 okay good oh okay just in terms of 4187 02:47:00,950 --> 02:46:58,880 precursors i want to expand this 4188 02:47:02,389 --> 02:47:00,960 discussion a little bit and that um i 4189 02:47:04,070 --> 02:47:02,399 know everyone's talking about the tight 4190 02:47:05,590 --> 02:47:04,080 timing and the rest but really one of 4191 02:47:07,670 --> 02:47:05,600 the most important precursors you could 4192 02:47:09,590 --> 02:47:07,680 do is do a survey that looks for near 4193 02:47:11,110 --> 02:47:09,600 earth objects right so here you can span 4194 02:47:12,309 --> 02:47:11,120 the number of objects we had and then 4195 02:47:13,510 --> 02:47:12,319 you have many more options you don't 4196 02:47:16,230 --> 02:47:13,520 know what options we have right now 4197 02:47:17,990 --> 02:47:16,240 right now we have very very few 4198 02:47:19,510 --> 02:47:18,000 options in terms of mission targets and 4199 02:47:21,030 --> 02:47:19,520 the rest and i think that could limit 4200 02:47:22,710 --> 02:47:21,040 that could be the show stopper right so 4201 02:47:24,230 --> 02:47:22,720 you want to avoid the show stoppers so 4202 02:47:26,630 --> 02:47:24,240 that's something i think nasa strongly 4203 02:47:33,110 --> 02:47:26,640 has to consider is some kind of space 4204 02:47:37,750 --> 02:47:35,269 so listening to the talks i sensed a lot 4205 02:47:40,469 --> 02:47:37,760 of interest in resources 4206 02:47:42,469 --> 02:47:40,479 and isru as a driver 4207 02:47:43,750 --> 02:47:42,479 and perhaps that's a way of answering 4208 02:47:46,389 --> 02:47:43,760 the why 4209 02:47:47,750 --> 02:47:46,399 and so a lot of commercial interest 4210 02:47:49,030 --> 02:47:47,760 on 4211 02:47:51,670 --> 02:47:49,040 what you do 4212 02:47:54,070 --> 02:47:51,680 with the asteroid and what is its 4213 02:47:56,309 --> 02:47:54,080 ultimate purpose and i think isru 4214 02:48:03,190 --> 02:47:56,319 should be captured as a potential driver 4215 02:48:08,870 --> 02:48:06,150 i have one comment under extensibility 4216 02:48:10,309 --> 02:48:08,880 if we for example pick up a rock from a 4217 02:48:11,990 --> 02:48:10,319 larger rock 4218 02:48:13,190 --> 02:48:12,000 is the question of should we leave 4219 02:48:15,670 --> 02:48:13,200 something 4220 02:48:18,630 --> 02:48:15,680 behind on the rock the big rock that we 4221 02:48:20,630 --> 02:48:18,640 took the little rock from 4222 02:48:26,550 --> 02:48:20,640 beacon or 4223 02:48:26,560 --> 02:48:30,309 okay thank you 4224 02:48:33,830 --> 02:48:32,230 anything else 4225 02:48:36,710 --> 02:48:33,840 the the other category that was 4226 02:48:39,429 --> 02:48:36,720 suggested that uh in addition to these 4227 02:48:47,670 --> 02:48:39,439 five was different business strategies 4228 02:48:53,269 --> 02:48:49,830 okay 4229 02:48:58,790 --> 02:48:56,630 um now this one's the harder one 4230 02:49:00,710 --> 02:48:58,800 we did the easy one and and this one we 4231 02:49:03,110 --> 02:49:00,720 we struggled with ourselves too so you 4232 02:49:04,950 --> 02:49:03,120 know even more than than summarizing 4233 02:49:06,870 --> 02:49:04,960 what was in the papers is what what are 4234 02:49:08,950 --> 02:49:06,880 findings relative to this initiative 4235 02:49:10,469 --> 02:49:08,960 planning and honestly like i said this 4236 02:49:13,110 --> 02:49:10,479 area in particular we didn't have quite 4237 02:49:15,349 --> 02:49:13,120 the guidance that we do now so but but 4238 02:49:16,550 --> 02:49:15,359 anyways i'll just talk through it and 4239 02:49:18,070 --> 02:49:16,560 the things that we would think would be 4240 02:49:19,750 --> 02:49:18,080 next steps is i think what this is 4241 02:49:21,990 --> 02:49:19,760 really more ordered around 4242 02:49:23,590 --> 02:49:22,000 um 4243 02:49:25,190 --> 02:49:23,600 establish a concise set of mission 4244 02:49:27,510 --> 02:49:25,200 objectives and figures of merit that 4245 02:49:29,269 --> 02:49:27,520 includes extensibility commercialization 4246 02:49:30,870 --> 02:49:29,279 considerations 4247 02:49:31,830 --> 02:49:30,880 perform an assessment of various mission 4248 02:49:33,990 --> 02:49:31,840 concept 4249 02:49:35,990 --> 02:49:34,000 options against these farms including 4250 02:49:38,790 --> 02:49:36,000 weighing technology approach and mission 4251 02:49:40,469 --> 02:49:38,800 enhancement options in doing so 4252 02:49:42,150 --> 02:49:40,479 focus the risk reduction activities 4253 02:49:44,230 --> 02:49:42,160 consistent with the mission concept 4254 02:49:47,590 --> 02:49:44,240 approach and leveraging the inputs and 4255 02:49:49,110 --> 02:49:47,600 consider a follow on our arm workshop 4256 02:49:50,790 --> 02:49:49,120 for sensor technologies that would 4257 02:49:53,670 --> 02:49:50,800 address the potential for integrated 4258 02:49:55,429 --> 02:49:53,680 sensing system that is able to support 4259 02:49:57,590 --> 02:49:55,439 all mission phases and broader nasa 4260 02:49:58,469 --> 02:49:57,600 exploration needs and and like i say we 4261 02:50:00,230 --> 02:49:58,479 really 4262 02:50:02,070 --> 02:50:00,240 you know this was a much more difficult 4263 02:50:03,510 --> 02:50:02,080 thing for us to do when we were talking 4264 02:50:05,190 --> 02:50:03,520 it but 4265 02:50:06,830 --> 02:50:05,200 this is what we have right now we'll 4266 02:50:09,910 --> 02:50:06,840 open the floor 4267 02:50:12,550 --> 02:50:09,920 thoughts just one comment the top one 4268 02:50:14,070 --> 02:50:12,560 would address the cost versus uh 4269 02:50:16,550 --> 02:50:14,080 objectives issue 4270 02:50:18,230 --> 02:50:16,560 some of the launch vehicle issues uh one 4271 02:50:20,469 --> 02:50:18,240 of the launch options could take the 4272 02:50:22,389 --> 02:50:20,479 entire budget and have nothing to launch 4273 02:50:24,630 --> 02:50:22,399 so that would be very helpful to 4274 02:50:29,110 --> 02:50:24,640 understand how much is actually being 4275 02:50:29,120 --> 02:50:41,590 anything else 4276 02:50:44,070 --> 02:50:42,309 uh 4277 02:50:45,910 --> 02:50:44,080 just looking at this list one thing i 4278 02:50:47,030 --> 02:50:45,920 think which could be done i think which 4279 02:50:47,750 --> 02:50:47,040 i'll put a different way which should be 4280 02:50:50,230 --> 02:50:47,760 done 4281 02:50:51,830 --> 02:50:50,240 is more incorporation of the small body 4282 02:50:53,269 --> 02:50:51,840 science community into all these 4283 02:50:54,630 --> 02:50:53,279 discussions 4284 02:50:56,150 --> 02:50:54,640 for some reason they're not being 4285 02:50:58,630 --> 02:50:56,160 included in any great degree or not 4286 02:51:00,309 --> 02:50:58,640 being invited and yet they have almost 4287 02:51:02,230 --> 02:51:00,319 all the expertise that exists on these 4288 02:51:04,550 --> 02:51:02,240 objects so i think we need to have 4289 02:51:06,469 --> 02:51:04,560 nasa sponsored workshops to discuss 4290 02:51:12,150 --> 02:51:06,479 these things 4291 02:51:16,870 --> 02:51:14,630 well until i heard deep space industries 4292 02:51:18,870 --> 02:51:16,880 talk i would have argued against more is 4293 02:51:20,230 --> 02:51:18,880 better 4294 02:51:22,630 --> 02:51:20,240 but if you guys are going to make fuel 4295 02:51:24,150 --> 02:51:22,640 out of it maybe more is better we are in 4296 02:51:25,110 --> 02:51:24,160 america anyway 4297 02:51:26,630 --> 02:51:25,120 um 4298 02:51:27,670 --> 02:51:26,640 that is our general approach to 4299 02:51:30,150 --> 02:51:27,680 everything 4300 02:51:31,510 --> 02:51:30,160 um but is is enough enough 4301 02:51:33,590 --> 02:51:31,520 i mean if a figure of merit is going to 4302 02:51:35,830 --> 02:51:33,600 be how much mass we bring back that may 4303 02:51:37,510 --> 02:51:35,840 drive a lot of decisions then 4304 02:51:39,590 --> 02:51:37,520 is one ton enough 4305 02:51:41,349 --> 02:51:39,600 if one ton is enough that may mean we 4306 02:51:42,630 --> 02:51:41,359 spend our money elsewhere in the system 4307 02:51:44,469 --> 02:51:42,640 rather than 4308 02:51:47,269 --> 02:51:44,479 you know you know are these guys going 4309 02:51:48,710 --> 02:51:47,279 to build a 15 meter bag or a 10 meter 4310 02:51:51,510 --> 02:51:48,720 bag 4311 02:51:53,830 --> 02:51:51,520 right so 4312 02:51:55,990 --> 02:51:53,840 is more always better if it ends up 4313 02:51:58,070 --> 02:51:56,000 killing the mission because we 4314 02:52:00,550 --> 02:51:58,080 we get ground into the ground on being 4315 02:52:01,990 --> 02:52:00,560 able to get that much then maybe 4316 02:52:05,269 --> 02:52:02,000 maybe we could pick a number that was 4317 02:52:07,590 --> 02:52:05,279 reasonable and that it just isn't uh 4318 02:52:09,190 --> 02:52:07,600 all right that's enough i think the top 4319 02:52:12,309 --> 02:52:09,200 figure of merit should be can you 4320 02:52:15,510 --> 02:52:12,319 sustain this activity 4321 02:52:17,349 --> 02:52:15,520 doing it once is not very interesting 4322 02:52:19,670 --> 02:52:17,359 so that should be the figure of merit is 4323 02:52:21,510 --> 02:52:19,680 it can you continue doing it 4324 02:52:23,670 --> 02:52:21,520 that would argue that the more comes in 4325 02:52:25,269 --> 02:52:23,680 the continuation than the repeatability 4326 02:52:26,790 --> 02:52:25,279 rather in the size of the initial 4327 02:52:28,550 --> 02:52:26,800 mission well then we're talking about 4328 02:52:29,990 --> 02:52:28,560 transferring of the technology to 4329 02:52:32,070 --> 02:52:30,000 private industry who wants to do it 4330 02:52:33,590 --> 02:52:32,080 again and again because 4331 02:52:35,750 --> 02:52:33,600 other than the scientists coming back 4332 02:52:37,750 --> 02:52:35,760 arguing that we need to do it again i 4333 02:52:38,870 --> 02:52:37,760 think this community's only signed up 4334 02:52:40,630 --> 02:52:38,880 for one 4335 02:52:42,630 --> 02:52:40,640 right 4336 02:52:44,950 --> 02:52:42,640 but i don't speak you want to spend that 4337 02:52:46,309 --> 02:52:44,960 much money to do it go ahead 4338 02:52:47,830 --> 02:52:46,319 please do well but it's not just that 4339 02:52:50,309 --> 02:52:47,840 we're spending the money to do lots of 4340 02:52:52,469 --> 02:52:50,319 other things develop the technology 4341 02:52:54,389 --> 02:52:52,479 practice evas do longer distances et 4342 02:52:56,950 --> 02:52:54,399 cetera et cetera so it's not just 4343 02:52:58,790 --> 02:52:56,960 spending all the money for one ton it's 4344 02:52:59,830 --> 02:52:58,800 for all the other things in addition so 4345 02:53:03,429 --> 02:52:59,840 as long as we can transfer the 4346 02:53:04,309 --> 02:53:03,439 technology to you does that satisfy the 4347 02:53:05,910 --> 02:53:04,319 the 4348 02:53:08,870 --> 02:53:05,920 continual stream of getting more and 4349 02:53:13,269 --> 02:53:11,269 what you decide to develop 4350 02:53:14,630 --> 02:53:13,279 if it's only done according to your 4351 02:53:16,870 --> 02:53:14,640 figures of merit 4352 02:53:19,110 --> 02:53:16,880 because you're the only one 4353 02:53:20,550 --> 02:53:19,120 making decisions about the system 4354 02:53:23,269 --> 02:53:20,560 means that the technology that gets 4355 02:53:25,830 --> 02:53:23,279 developed may not be applicable or 4356 02:53:28,389 --> 02:53:25,840 useful to the private sector so 4357 02:53:30,070 --> 02:53:28,399 that's why a cots like approach 4358 02:53:32,070 --> 02:53:30,080 you know where nasa said we want this 4359 02:53:34,070 --> 02:53:32,080 many tons delivered to the space station 4360 02:53:35,670 --> 02:53:34,080 what else you do with the dragon system 4361 02:53:37,429 --> 02:53:35,680 is up to you if you're going to sell it 4362 02:53:38,710 --> 02:53:37,439 back to us that's a different story 4363 02:53:40,469 --> 02:53:38,720 right if you're going to sell back to us 4364 02:53:42,870 --> 02:53:40,479 now we help ourselves by bringing more 4365 02:53:44,950 --> 02:53:42,880 to sis luna's face 4366 02:53:47,110 --> 02:53:44,960 mark did you want to add something well 4367 02:53:49,349 --> 02:53:47,120 i was just going to try to help heather 4368 02:53:51,510 --> 02:53:49,359 turned around and cued me there's more 4369 02:53:53,670 --> 02:53:51,520 than one aspect to extensibility there's 4370 02:53:54,469 --> 02:53:53,680 extensibility of using the asteroid more 4371 02:53:56,710 --> 02:53:54,479 per 4372 02:53:58,309 --> 02:53:56,720 industry things there's extensibility of 4373 02:54:00,230 --> 02:53:58,319 using the technology 4374 02:54:02,230 --> 02:54:00,240 but there's also extensibility that 4375 02:54:04,389 --> 02:54:02,240 steve stitch will talk about in the crew 4376 02:54:06,230 --> 02:54:04,399 session tomorrow of using these 4377 02:54:08,790 --> 02:54:06,240 technologies and systems to accomplish 4378 02:54:10,230 --> 02:54:08,800 missions beyond this lunar missions mars 4379 02:54:11,030 --> 02:54:10,240 missions other things 4380 02:54:13,110 --> 02:54:11,040 so 4381 02:54:14,630 --> 02:54:13,120 the broader nasa team that that is 4382 02:54:16,630 --> 02:54:14,640 working this is looking at it from 4383 02:54:18,950 --> 02:54:16,640 multiple points of view so 4384 02:54:21,510 --> 02:54:18,960 to be fair this session is on the 4385 02:54:24,309 --> 02:54:21,520 redirect correct 4386 02:54:25,990 --> 02:54:24,319 yes so that's that's the form when we 4387 02:54:28,309 --> 02:54:26,000 talk about extensibility we're talking 4388 02:54:30,630 --> 02:54:28,319 about extensibility of those elements 4389 02:54:31,910 --> 02:54:30,640 correct and that's that's james is right 4390 02:54:34,389 --> 02:54:31,920 that's exactly what i was going to say 4391 02:54:36,389 --> 02:54:34,399 is in this session you focus on those 4392 02:54:37,990 --> 02:54:36,399 asteroid pieces but in other sessions 4393 02:54:39,670 --> 02:54:38,000 the broader nasa team is considering 4394 02:54:41,190 --> 02:54:39,680 other aspects although the selection 4395 02:54:42,630 --> 02:54:41,200 material might 4396 02:54:44,309 --> 02:54:42,640 you know might 4397 02:54:46,150 --> 02:54:44,319 hinder or help 4398 02:54:49,269 --> 02:54:46,160 the future missions 4399 02:54:51,750 --> 02:54:49,279 so there is 4400 02:54:54,309 --> 02:54:51,760 as you address your figures of merit you 4401 02:54:55,990 --> 02:54:54,319 want to look at is there a potential 4402 02:54:57,830 --> 02:54:56,000 follow-on use to this does someone pick 4403 02:54:59,590 --> 02:54:57,840 up this technology and make it available 4404 02:55:00,309 --> 02:54:59,600 to us 10 years later when we next need 4405 02:55:06,150 --> 02:55:00,319 it 4406 02:55:08,469 --> 02:55:06,160 we developed a lot of technology that 4407 02:55:10,070 --> 02:55:08,479 doesn't help us follow on so having that 4408 02:55:11,990 --> 02:55:10,080 transition into the commercial sector 4409 02:55:13,429 --> 02:55:12,000 when we're doing that right now in the 4410 02:55:14,790 --> 02:55:13,439 on the science side we've been building 4411 02:55:17,349 --> 02:55:14,800 a lot of technology for the last 10 4412 02:55:18,950 --> 02:55:17,359 years and if we can't get it to the 4413 02:55:20,550 --> 02:55:18,960 commercial industry 4414 02:55:22,150 --> 02:55:20,560 to sustain it we can't sustain it 4415 02:55:24,550 --> 02:55:22,160 anymore so we're abandoning technology 4416 02:55:26,070 --> 02:55:24,560 that we've been building for a while 4417 02:55:27,349 --> 02:55:26,080 because we haven't thought through the 4418 02:55:28,630 --> 02:55:27,359 what's next 4419 02:55:31,429 --> 02:55:28,640 and didn't have a way to hand it off 4420 02:55:32,550 --> 02:55:31,439 there's two points that i guess i was 4421 02:55:34,070 --> 02:55:32,560 going to bring up 4422 02:55:38,150 --> 02:55:34,080 an example 4423 02:55:40,710 --> 02:55:38,160 of why you need to actually have some 4424 02:55:43,110 --> 02:55:40,720 discussion along this line of 4425 02:55:45,990 --> 02:55:43,120 of technology is even within sub 4426 02:55:48,630 --> 02:55:46,000 technologies sap technologies and let's 4427 02:55:50,309 --> 02:55:48,640 say that we all agree that well we're 4428 02:55:52,230 --> 02:55:50,319 probably going to go down the hall 4429 02:55:53,590 --> 02:55:52,240 thruster route just because that's the 4430 02:55:55,190 --> 02:55:53,600 most mature 4431 02:55:56,870 --> 02:55:55,200 and that we could bring online to do 4432 02:55:58,870 --> 02:55:56,880 this kind of mission in this timeframe 4433 02:56:01,190 --> 02:55:58,880 even if you got consensus about that 4434 02:56:03,349 --> 02:56:01,200 which you wouldn't 4435 02:56:04,230 --> 02:56:03,359 the fact of the matter is if 4436 02:56:12,150 --> 02:56:04,240 the 4437 02:56:15,110 --> 02:56:12,160 goes with 12.5 4438 02:56:17,269 --> 02:56:15,120 kilowatt individual thrusters 4439 02:56:19,750 --> 02:56:17,279 the geocom community would say those are 4440 02:56:22,309 --> 02:56:19,760 useless for our needs they don't want 4441 02:56:24,389 --> 02:56:22,319 that larger thruster so 4442 02:56:26,469 --> 02:56:24,399 transferring technology 4443 02:56:28,950 --> 02:56:26,479 is very dependent on 4444 02:56:30,950 --> 02:56:28,960 what the rest of the community wants and 4445 02:56:33,510 --> 02:56:30,960 we need to make we need to make a point 4446 02:56:35,269 --> 02:56:33,520 that that that has to be discussed and 4447 02:56:36,950 --> 02:56:35,279 acknowledged in some way so that's the 4448 02:56:39,030 --> 02:56:36,960 first point that i wanted to make and i 4449 02:56:40,710 --> 02:56:39,040 think we should try to capture it within 4450 02:56:42,950 --> 02:56:40,720 this this type of discussion that you're 4451 02:56:45,349 --> 02:56:42,960 bringing up on findings 4452 02:56:46,150 --> 02:56:45,359 the second goes back to 4453 02:56:48,950 --> 02:56:46,160 uh 4454 02:56:51,190 --> 02:56:48,960 how we're dealing with 4455 02:56:52,830 --> 02:56:51,200 the business case because the entire 4456 02:56:56,070 --> 02:56:52,840 discussion that you just 4457 02:56:58,150 --> 02:56:56,080 heard cots versus well the government 4458 02:57:00,630 --> 02:56:58,160 goes and does this as a one-off and then 4459 02:57:02,870 --> 02:57:00,640 sends you know and then you know 4460 02:57:04,469 --> 02:57:02,880 says okay now we could we could uh you 4461 02:57:06,870 --> 02:57:04,479 know hand off the technologies to be 4462 02:57:08,870 --> 02:57:06,880 sold back to us that's that's 4463 02:57:11,510 --> 02:57:08,880 you know completely different mindset of 4464 02:57:13,110 --> 02:57:11,520 how we should go about this and 4465 02:57:15,030 --> 02:57:13,120 i think that there's going to be very 4466 02:57:16,469 --> 02:57:15,040 big differences in how partnerships 4467 02:57:17,990 --> 02:57:16,479 occur 4468 02:57:33,670 --> 02:57:18,000 given different scenarios on the 4469 02:57:39,030 --> 02:57:37,750 okay um any la it is for 5 30 so we've 4470 02:57:40,070 --> 02:57:39,040
