Suffredini good afternoon it's great 19 00:00:54,599 --> 00:00:52,010 to be here on the first launch of the 20 00:00:57,240 --> 00:00:54,609 year to the International Space Station 21 00:01:01,660 --> 00:00:57,250 spacex 5 of course is carrying 22 00:01:04,990 --> 00:01:01,670 much-needed cargo to the to the orbiting 23 00:01:07,600 --> 00:01:05,000 outpost the SpaceX folks have worked 24 00:01:10,630 --> 00:01:07,610 really closely with us this time of all 25 00:01:13,240 --> 00:01:10,640 the cargo on board we have about a 1.8 26 00:01:14,560 --> 00:01:13,250 metric tons of pressurized cargo I think 27 00:01:18,490 --> 00:01:14,570 that's the most we've crammed into a 28 00:01:20,950 --> 00:01:18,500 dragon to date and that's been with the 29 00:01:24,069 --> 00:01:20,960 help of the SpaceX folks have used quite 30 00:01:25,740 --> 00:01:24,079 a bit of ingenuity to help us put items 31 00:01:29,139 --> 00:01:25,750 and all the little cracks and crevices 32 00:01:31,149 --> 00:01:29,149 as we kind of lean on the Dragon vehicle 33 00:01:33,460 --> 00:01:31,159 to supply ISS here for the next little 34 00:01:37,359 --> 00:01:33,470 while until the orbital folks are flying 35 00:01:38,800 --> 00:01:37,369 again this year of course is no 36 00:01:40,210 --> 00:01:38,810 different than any other year that I've 37 00:01:43,719 --> 00:01:40,220 been in this program there's always 38 00:01:45,310 --> 00:01:43,729 major changes happening on board and of 39 00:01:48,219 --> 00:01:45,320 course now we have a full breadth of 40 00:01:49,959 --> 00:01:48,229 research going on as well I know Julie 41 00:01:51,880 --> 00:01:49,969 and folks chatted with you about the 42 00:01:55,149 --> 00:01:51,890 research specifically so well I won't 43 00:01:57,730 --> 00:01:55,159 dwell on that but the program is got a 44 00:02:00,310 --> 00:01:57,740 couple of major changes happening this 45 00:02:02,709 --> 00:02:00,320 year the first one is we're configuring 46 00:02:04,990 --> 00:02:02,719 the vehicle to have docking again for 47 00:02:06,340 --> 00:02:05,000 the first time on ISS and shuttle 48 00:02:08,590 --> 00:02:06,350 retired 49 00:02:11,290 --> 00:02:08,600 we call it the International docking 50 00:02:13,870 --> 00:02:11,300 adapter we intend to have two onboard 51 00:02:16,330 --> 00:02:13,880 the station a one in the forward 52 00:02:18,340 --> 00:02:16,340 where the where shovels used to dock and 53 00:02:22,060 --> 00:02:18,350 then another one on the zenith port if 54 00:02:25,030 --> 00:02:22,070 no to that work includes the two docking 55 00:02:28,840 --> 00:02:25,040 ports rearranging the vehicle to move 56 00:02:31,390 --> 00:02:28,850 the pressurized multi-purpose module 57 00:02:33,190 --> 00:02:31,400 that is sitting on node one nadir we're 58 00:02:35,890 --> 00:02:33,200 gonna move that to node three forward 59 00:02:38,410 --> 00:02:35,900 we're gonna move PMA three off the end 60 00:02:40,030 --> 00:02:38,420 of node 3 and put it on no to zenith so 61 00:02:42,820 --> 00:02:40,040 the other docking adapter can be put 62 00:02:46,720 --> 00:02:42,830 there and then birthings will occur at 63 00:02:49,000 --> 00:02:46,730 node 2 nadir and node 1 nadir in 64 00:02:52,810 --> 00:02:49,010 addition to the docking systems we also 65 00:02:55,270 --> 00:02:52,820 have to install the targets necessary to 66 00:02:57,130 --> 00:02:55,280 allow the in the closing proximity 67 00:02:58,840 --> 00:02:57,140 operations to occur and the 68 00:03:00,460 --> 00:02:58,850 communication system so we're gonna have 69 00:03:02,620 --> 00:03:00,470 a different communication systems on 70 00:03:05,080 --> 00:03:02,630 board in order to allow command and 71 00:03:07,360 --> 00:03:05,090 control between the ISS and the 72 00:03:10,030 --> 00:03:07,370 approaching vehicles so this is quite a 73 00:03:12,100 --> 00:03:10,040 bit of work our plan has always been to 74 00:03:14,680 --> 00:03:12,110 have a docking capability in place and 75 00:03:17,680 --> 00:03:14,690 operational by the end of 2015 and we're 76 00:03:21,040 --> 00:03:17,690 still on track to do that the first real 77 00:03:22,510 --> 00:03:21,050 steps you'll see us take and and Dragon 78 00:03:26,650 --> 00:03:22,520 is bringing up some of this hardware is 79 00:03:29,140 --> 00:03:26,660 to these three EVs that'll occur once 80 00:03:31,090 --> 00:03:29,150 dragon arrives and get settled in we 81 00:03:33,850 --> 00:03:31,100 have three days they're going to start 82 00:03:36,400 --> 00:03:33,860 the reconfiguration work once the EVs 83 00:03:38,050 --> 00:03:36,410 are complete then at some point in the 84 00:03:40,060 --> 00:03:38,060 future we'll be ready to move the PMM 85 00:03:41,920 --> 00:03:40,070 whenever the ops team is is ready to 86 00:03:45,340 --> 00:03:41,930 make that that move and that'll be the 87 00:03:47,560 --> 00:03:45,350 most obvious change until spacex 7 88 00:03:49,150 --> 00:03:47,570 arrives with the first of the docking 89 00:03:52,510 --> 00:03:49,160 adapters that will be installed and that 90 00:03:57,010 --> 00:03:52,520 one will be on on node 2 forward so all 91 00:03:58,630 --> 00:03:57,020 that work is is on track and we'll have 92 00:04:00,400 --> 00:03:58,640 it all complete as I said by the end of 93 00:04:01,210 --> 00:04:00,410 this calendar year that's the that's the 94 00:04:03,400 --> 00:04:01,220 plan right now 95 00:04:05,280 --> 00:04:03,410 in addition that of course we have the 96 00:04:08,620 --> 00:04:05,290 very exciting one-year mission coming up 97 00:04:10,720 --> 00:04:08,630 and it's that crew launches to the 98 00:04:13,810 --> 00:04:10,730 International Space Station Scott and 99 00:04:15,520 --> 00:04:13,820 McHale will launch this March at the end 100 00:04:18,070 --> 00:04:15,530 of this March and begin their one-year 101 00:04:22,000 --> 00:04:18,080 increment onboard ISS and of course that 102 00:04:24,040 --> 00:04:22,010 is a big step towards human exploration 103 00:04:26,680 --> 00:04:24,050 beyond low Earth orbit we always talk 104 00:04:27,680 --> 00:04:26,690 about ISS being the first step this is a 105 00:04:30,140 --> 00:04:27,690 pretty big 106 00:04:31,880 --> 00:04:30,150 part of that first step is to to do this 107 00:04:33,950 --> 00:04:31,890 one-year mission and and study the 108 00:04:36,800 --> 00:04:33,960 effects it has this is the first of 109 00:04:38,960 --> 00:04:36,810 several we hope to do over over the next 110 00:04:41,990 --> 00:04:38,970 several years and so we're looking 111 00:04:44,330 --> 00:04:42,000 forward to that as well and so with that 112 00:04:47,300 --> 00:04:44,340 I'll pass on the Hans who will talk to 113 00:04:50,150 --> 00:04:47,310 you about the SpaceX readiness yeah 114 00:04:51,500 --> 00:04:50,160 thank you very much and happy new year 115 00:04:53,930 --> 00:04:51,510 and really happy to be here for the 116 00:04:57,590 --> 00:04:53,940 first mission in 2015 117 00:05:01,180 --> 00:04:57,600 5:09 flight 14 and for Dragon it's 118 00:05:04,640 --> 00:05:01,190 actually the seventh flight CRS five 119 00:05:07,250 --> 00:05:04,650 it's gonna be a I want to point out I do 120 00:05:10,550 --> 00:05:07,260 expect attention on the on the first 121 00:05:12,050 --> 00:05:10,560 stage manoeuvres and landing but I do 122 00:05:14,270 --> 00:05:12,060 want to point out that the main mission 123 00:05:15,560 --> 00:05:14,280 is absolutely to get the cargo to the 124 00:05:18,320 --> 00:05:15,570 station and to make sure that the 125 00:05:22,910 --> 00:05:18,330 station supply is steady and unstable 126 00:05:25,880 --> 00:05:22,920 and unreliable and that SpaceX basically 127 00:05:27,710 --> 00:05:25,890 does everything they can to to keep this 128 00:05:29,960 --> 00:05:27,720 up and make sure that you get all the 129 00:05:33,380 --> 00:05:29,970 cargo you need whether it's experiments 130 00:05:36,020 --> 00:05:33,390 or supplies as always there's a mix of 131 00:05:37,700 --> 00:05:36,030 that on Dragon there's also going to be 132 00:05:39,860 --> 00:05:37,710 external payloads I think there's one 133 00:05:40,430 --> 00:05:39,870 external payload this time I'm flying in 134 00:05:46,130 --> 00:05:40,440 the trunk 135 00:05:49,460 --> 00:05:46,140 it's going to be extracted as part of 136 00:05:50,900 --> 00:05:49,470 the other mission I can talk about a 137 00:05:55,310 --> 00:05:50,910 little bit about the the main mission 138 00:05:57,140 --> 00:05:55,320 here um it's a essentially very similar 139 00:06:02,380 --> 00:05:57,150 to the last year's full mission that we 140 00:06:05,120 --> 00:06:02,390 had and I think it was a Templar and 141 00:06:07,010 --> 00:06:05,130 basically first stage burned for you 142 00:06:08,840 --> 00:06:07,020 what you see here and you and you sit on 143 00:06:10,790 --> 00:06:08,850 the lower side it's going to be very 144 00:06:12,860 --> 00:06:10,800 similar it's going to be at close to 145 00:06:15,050 --> 00:06:12,870 three-minute burn then stage separation 146 00:06:17,420 --> 00:06:15,060 he both through the second stage ignited 147 00:06:19,010 --> 00:06:17,430 the weather is favorable and you will 148 00:06:22,610 --> 00:06:19,020 see the second stage continued for 149 00:06:25,280 --> 00:06:22,620 another seven minutes before we get into 150 00:06:28,430 --> 00:06:25,290 orbit in orbit will take us 30 seconds 151 00:06:31,970 --> 00:06:28,440 priming and maneuvering until we deploy 152 00:06:34,159 --> 00:06:31,980 dragon there's nothing different from 153 00:06:36,590 --> 00:06:34,169 the last mission as far as you can tell 154 00:06:38,640 --> 00:06:36,600 from the outside it's going to be some 155 00:06:41,580 --> 00:06:38,650 differences after that and 156 00:06:43,860 --> 00:06:41,590 I get to that in a second before that I 157 00:06:46,170 --> 00:06:43,870 continue with dragon dragon continues 158 00:06:49,680 --> 00:06:46,180 for about two days it's actually 44 159 00:06:52,379 --> 00:06:49,690 hours on orbit maneuvering and phasing 160 00:06:56,450 --> 00:06:52,389 and height adjustments until it will be 161 00:07:00,090 --> 00:06:56,460 grappled by the station arm once it is 162 00:07:02,999 --> 00:07:00,100 birthed to the station it will stay 163 00:07:07,080 --> 00:07:03,009 there for currently scheduled 30 days 164 00:07:09,360 --> 00:07:07,090 about I think February 7 is the current 165 00:07:14,730 --> 00:07:09,370 release date deploy date from the 166 00:07:17,730 --> 00:07:14,740 station and then come back and get water 167 00:07:20,310 --> 00:07:17,740 in the Pacific a couple hundred miles to 168 00:07:24,360 --> 00:07:20,320 the west of Long Beach we will wait 169 00:07:25,890 --> 00:07:24,370 there at the boat and catch dragon 170 00:07:28,830 --> 00:07:25,900 basically and put it on the boat and 171 00:07:31,650 --> 00:07:28,840 bring it back to the harbor for further 172 00:07:36,270 --> 00:07:31,660 payload downtown payload in that case 173 00:07:40,050 --> 00:07:36,280 processing and that will then the be the 174 00:07:42,150 --> 00:07:40,060 end of the mission so when the first in 175 00:07:43,529 --> 00:07:42,160 the second stage separate the first 176 00:07:46,230 --> 00:07:43,539 stage will continue and they will 177 00:07:50,550 --> 00:07:46,240 continue on a secondary non mission 178 00:07:54,149 --> 00:07:50,560 critical I guess experiment to some 179 00:07:56,040 --> 00:07:54,159 extent it will turn around it will 180 00:08:00,719 --> 00:07:56,050 perform a what's called a boost back 181 00:08:05,120 --> 00:08:00,729 burn that boots back burn brings the 182 00:08:10,050 --> 00:08:05,130 stage closer closer back in it will then 183 00:08:11,969 --> 00:08:10,060 continue to just coast and as it gets 184 00:08:13,469 --> 00:08:11,979 into closer to the atmosphere it will 185 00:08:16,050 --> 00:08:13,479 perform an entry per and the entry burn 186 00:08:18,659 --> 00:08:16,060 will slow the stage down and that 187 00:08:21,839 --> 00:08:18,669 reduces the loads on the stage so it's 188 00:08:23,730 --> 00:08:21,849 uh it's supposed to - putting the stage 189 00:08:25,500 --> 00:08:23,740 then through the atmosphere and that 190 00:08:27,649 --> 00:08:25,510 will be followed by a landing burn and 191 00:08:32,490 --> 00:08:27,659 the landing burn is targeted to a 192 00:08:35,640 --> 00:08:32,500 autonomous spaceport thrown ship that is 193 00:08:37,529 --> 00:08:35,650 the official word for it so the drone 194 00:08:38,850 --> 00:08:37,539 ship sits there right now and it's 195 00:08:43,140 --> 00:08:38,860 basically waiting for the mission to 196 00:08:46,890 --> 00:08:43,150 happen that I'm pretty sure this will be 197 00:08:48,690 --> 00:08:46,900 will be very exciting it's as I said 198 00:08:52,320 --> 00:08:48,700 it's an experiment 199 00:08:53,820 --> 00:08:52,330 there's a so certain likelihood that 200 00:08:55,680 --> 00:08:53,830 this will not work out right that 201 00:08:58,320 --> 00:08:55,690 something will go wrong it's the first 202 00:09:01,590 --> 00:08:58,330 time we try this nobody as I ever tried 203 00:09:04,020 --> 00:09:01,600 that to our knowledge and and so 204 00:09:09,750 --> 00:09:04,030 currently Ilan put a probability of 50% 205 00:09:11,820 --> 00:09:09,760 on this on this part really as an 206 00:09:14,010 --> 00:09:11,830 experimental part basically of the 207 00:09:16,560 --> 00:09:14,020 emission again it's not part of the 208 00:09:18,960 --> 00:09:16,570 mission you will focus no entire company 209 00:09:21,300 --> 00:09:18,970 you've worked very hard to make the ICS 210 00:09:22,020 --> 00:09:21,310 part and the ascent part and the cargo 211 00:09:24,810 --> 00:09:22,030 part 212 00:09:26,010 --> 00:09:24,820 happen I just wanted to bring it up on 213 00:09:29,310 --> 00:09:26,020 the side because I guess you're probably 214 00:09:33,240 --> 00:09:29,320 interested in that too I guess what's 215 00:09:36,540 --> 00:09:33,250 all I had major all right good afternoon 216 00:09:38,940 --> 00:09:36,550 well after a warm weekend of the Space 217 00:09:41,550 --> 00:09:38,950 Coast we are seeing that increased 218 00:09:43,680 --> 00:09:41,560 cloudiness and wind shift around from 219 00:09:45,420 --> 00:09:43,690 the south to the north associated with a 220 00:09:47,340 --> 00:09:45,430 cold front that has since moved into our 221 00:09:49,050 --> 00:09:47,350 area and slowed down and over the 222 00:09:53,580 --> 00:09:49,060 Central Coast over the Central Florida 223 00:09:58,410 --> 00:09:53,590 area I should say as we get into excuse 224 00:10:00,330 --> 00:09:58,420 me fortunately that front will not stall 225 00:10:02,280 --> 00:10:00,340 out I like the last one did and will 226 00:10:04,740 --> 00:10:02,290 continue to slowly push to the south and 227 00:10:06,390 --> 00:10:04,750 what that means is the cloudiness will 228 00:10:08,430 --> 00:10:06,400 decrease the clouds will start to thin 229 00:10:09,990 --> 00:10:08,440 out and that has allowed us to decrease 230 00:10:11,970 --> 00:10:10,000 our probability of violations from 40% 231 00:10:15,060 --> 00:10:11,980 that we had over the past couple days to 232 00:10:17,370 --> 00:10:15,070 30% as we do have now we can go to the 233 00:10:19,170 --> 00:10:17,380 visible satellite shot please you can 234 00:10:22,290 --> 00:10:19,180 see those clouds a little as the Sun 235 00:10:23,670 --> 00:10:22,300 slowly starts to go down you can see you 236 00:10:25,350 --> 00:10:23,680 can still see the clouds there associate 237 00:10:26,550 --> 00:10:25,360 with the front again slowly start and 238 00:10:28,530 --> 00:10:26,560 move to the southeast and we really 239 00:10:29,910 --> 00:10:28,540 won't see a good push of clouds move out 240 00:10:32,190 --> 00:10:29,920 until Wednesday on Thursday that's when 241 00:10:35,220 --> 00:10:32,200 we'll really see those that front make 242 00:10:37,530 --> 00:10:35,230 its way to the southeast so for tomorrow 243 00:10:39,180 --> 00:10:37,540 morning we are looking at scattered 244 00:10:40,710 --> 00:10:39,190 clouds in the lower levels and mid 245 00:10:43,190 --> 00:10:40,720 levels and then the upper levels will be 246 00:10:45,000 --> 00:10:43,200 mostly cloudy skies at about 24,000 feet 247 00:10:47,190 --> 00:10:45,010 you can see right there the forecast 248 00:10:49,440 --> 00:10:47,200 2,000 feet scattered scattered in the 249 00:10:51,990 --> 00:10:49,450 mid levels and broken about 24,000 feet 250 00:10:53,730 --> 00:10:52,000 and the mid-levels is really will where 251 00:10:55,710 --> 00:10:53,740 we will be focused is associated with a 252 00:10:57,030 --> 00:10:55,720 thick cloud rule we'll be looking at 253 00:10:59,160 --> 00:10:57,040 clouds anywhere between 0 degrees and 254 00:11:00,860 --> 00:10:59,170 minus 20 degrees Celsius and in this 255 00:11:02,750 --> 00:11:00,870 case that's about 15 to 20 256 00:11:05,329 --> 00:11:02,760 feet so in that areas we'll be looking 257 00:11:06,620 --> 00:11:05,339 for clouds over the launchpad and seeing 258 00:11:09,620 --> 00:11:06,630 of the cloud any part of that cloud deck 259 00:11:12,790 --> 00:11:09,630 is that's greater than 45 or 4500 feet 260 00:11:14,960 --> 00:11:12,800 thick is between 15 and 20,000 feet 261 00:11:16,820 --> 00:11:14,970 visibility no issues winds will be on 262 00:11:18,650 --> 00:11:16,830 the north-northeast at 5 to 10 miles an 263 00:11:20,930 --> 00:11:18,660 hour and no issues with weather and 264 00:11:22,850 --> 00:11:20,940 temperature about 64 degrees again a 30% 265 00:11:25,220 --> 00:11:22,860 chance of violation associated with the 266 00:11:26,870 --> 00:11:25,230 cloud rule if we go to the Friday 267 00:11:28,100 --> 00:11:26,880 morning if we have to slip into slip 268 00:11:29,510 --> 00:11:28,110 into Friday morning I really know what 269 00:11:30,829 --> 00:11:29,520 he's with clouds our concern really 270 00:11:33,440 --> 00:11:30,839 becomes more of an issue with the flight 271 00:11:34,880 --> 00:11:33,450 through precip when we see the onshore 272 00:11:37,220 --> 00:11:34,890 flow and this isn't really a direct 273 00:11:38,930 --> 00:11:37,230 onshore flow we're seeing more of a with 274 00:11:41,930 --> 00:11:38,940 the north-northeast conditions as more 275 00:11:43,070 --> 00:11:41,940 of indirect onshore flow we do increase 276 00:11:44,540 --> 00:11:43,080 our chances of rain showers in the 277 00:11:46,100 --> 00:11:44,550 morning particularly a morning 278 00:11:47,990 --> 00:11:46,110 especially we have two or three days of 279 00:11:49,730 --> 00:11:48,000 onshore flow so that's what we're gonna 280 00:11:51,700 --> 00:11:49,740 be really focused on is the occasional 281 00:11:53,420 --> 00:11:51,710 shower coming across a launch pad and 282 00:11:55,610 --> 00:11:53,430 the concern with a flight through 283 00:11:57,050 --> 00:11:55,620 precipitation so again when's be held in 284 00:11:58,790 --> 00:11:57,060 north northeast 5 to 10 miles an hour 285 00:12:00,740 --> 00:11:58,800 and temperatures will be a little cooler 286 00:12:02,060 --> 00:12:00,750 as that front does finally get make its 287 00:12:03,829 --> 00:12:02,070 way down to the south temperatures will 288 00:12:05,240 --> 00:12:03,839 be about 10 degrees cooler then we will 289 00:12:07,630 --> 00:12:05,250 see tomorrow morning down to about the 290 00:12:10,610 --> 00:12:07,640 mid 50s and only a 20% chance of 291 00:12:11,840 --> 00:12:10,620 Violation anytime we have an 292 00:12:13,490 --> 00:12:11,850 instantaneous window it does make it a 293 00:12:15,230 --> 00:12:13,500 little more dicey because we can't 294 00:12:18,350 --> 00:12:15,240 provide a clear time and things like 295 00:12:20,570 --> 00:12:18,360 that so but otherwise like I said 296 00:12:23,210 --> 00:12:20,580 chances are low for violation looking at 297 00:12:24,980 --> 00:12:23,220 30% for tomorrow morning and 20% for 298 00:12:26,810 --> 00:12:24,990 Friday morning so looking forward to it 299 00:12:29,530 --> 00:12:26,820 and great lunch thank you okay thank you 300 00:12:32,449 --> 00:12:29,540 alright we'll take questions now we have 301 00:12:35,180 --> 00:12:32,459 news media and social media members from 302 00:12:37,160 --> 00:12:35,190 the NASA social here as well as a couple 303 00:12:39,650 --> 00:12:37,170 of reporters on our phone bridge and we 304 00:12:42,350 --> 00:12:39,660 also have opened up for online questions 305 00:12:44,570 --> 00:12:42,360 if you're online you're watching Jason 306 00:12:47,060 --> 00:12:44,580 Townsend from NASA headquarters social 307 00:12:50,660 --> 00:12:47,070 media is here and you can send questions 308 00:12:52,699 --> 00:12:50,670 to the hashtag ask NASA and we will get 309 00:12:55,040 --> 00:12:52,709 to those but we'll start off here for 310 00:12:57,380 --> 00:12:55,050 folks please wait for the microphone 311 00:12:59,019 --> 00:12:57,390 state your name and affiliation and to 312 00:13:04,510 --> 00:12:59,029 whom you're addressing your question and 313 00:13:09,130 --> 00:13:07,000 hello Marcia Dunn Associated Press for 314 00:13:11,230 --> 00:13:09,140 mr. clinics men I'd like to hear a 315 00:13:13,450 --> 00:13:11,240 little bit more about the experiment at 316 00:13:16,660 --> 00:13:13,460 the end of the flight how close will the 317 00:13:19,000 --> 00:13:16,670 closest SpaceX employees be to the drone 318 00:13:23,740 --> 00:13:19,010 when all this is happening how will you 319 00:13:25,750 --> 00:13:23,750 record it also how many by what by what 320 00:13:28,630 --> 00:13:25,760 time do you expect touchdown to occur 321 00:13:30,550 --> 00:13:28,640 and is this all pre-programmed or will 322 00:13:32,590 --> 00:13:30,560 there be flight controllers being able 323 00:13:35,170 --> 00:13:32,600 to divert it if there's a problem of 324 00:13:37,449 --> 00:13:35,180 some sort so the the first stage is 325 00:13:39,810 --> 00:13:37,459 subject to arrange control in terms of 326 00:13:42,340 --> 00:13:39,820 flight safety so that that much is clear 327 00:13:45,790 --> 00:13:42,350 it has its own safety package basically 328 00:13:47,199 --> 00:13:45,800 on board but there's there's no the 329 00:13:49,810 --> 00:13:47,209 autonomous part on the spaceship 330 00:13:51,940 --> 00:13:49,820 indicates there's just nobody nearby on 331 00:13:54,400 --> 00:13:51,950 the on the boat or you know within a 332 00:13:56,590 --> 00:13:54,410 certain safe distance I want to say 10 333 00:13:58,630 --> 00:13:56,600 miles roughly something like that but 334 00:14:01,560 --> 00:13:58,640 I'm not sure about the number it's a 335 00:14:05,730 --> 00:14:01,570 safe distance that basically we the I 336 00:14:08,110 --> 00:14:05,740 believe the Range Safety Office tells us 337 00:14:10,870 --> 00:14:08,120 that some analysis attached to it that 338 00:14:13,150 --> 00:14:10,880 this is a safe distance so no employee 339 00:14:16,570 --> 00:14:13,160 or anybody else is nearby the landing 340 00:14:23,680 --> 00:14:16,580 site or the toy the space port drone 341 00:14:25,990 --> 00:14:23,690 ship so so that that's what what keeps 342 00:14:28,810 --> 00:14:26,000 that safe and I think you asked how we 343 00:14:32,199 --> 00:14:28,820 record this we have cameras on the 344 00:14:34,329 --> 00:14:32,209 vehicle we have telemetry on the vehicle 345 00:14:37,030 --> 00:14:34,339 of course there's going to be a 346 00:14:40,329 --> 00:14:37,040 telemetry boat nearby recording a 347 00:14:42,190 --> 00:14:40,339 telemetry we will not I believe we may 348 00:14:44,410 --> 00:14:42,200 have real-time but we will likely not 349 00:14:47,170 --> 00:14:44,420 have real-time information and I want to 350 00:14:48,519 --> 00:14:47,180 point this out from from the Cape the 351 00:14:51,430 --> 00:14:48,529 landing site is basically over the 352 00:14:53,650 --> 00:14:51,440 horizon and we have no direct connection 353 00:14:55,510 --> 00:14:53,660 we lose we lose the direct connection 354 00:14:59,890 --> 00:14:55,520 with the vehicle on point in time but we 355 00:15:04,360 --> 00:14:59,900 do record the data locally you know near 356 00:15:09,069 --> 00:15:04,370 the near the dropship so that we can 357 00:15:13,410 --> 00:15:09,079 really create whatever happened then how 358 00:15:16,900 --> 00:15:13,420 many minutes oh the time yes so I'm the 359 00:15:18,789 --> 00:15:16,910 the nominal shutdown of the 360 00:15:21,729 --> 00:15:18,799 the first-stage booster is nine minutes 361 00:15:23,650 --> 00:15:21,739 after liftoff it's actually just a 362 00:15:27,279 --> 00:15:23,660 little bit ahead of the Dragon deploy 363 00:15:28,719 --> 00:15:27,289 and we will we will in the webcast we 364 00:15:34,889 --> 00:15:28,729 will focus on the dragon and the main 365 00:15:36,969 --> 00:15:34,899 mission with CBS with two questions 366 00:15:38,979 --> 00:15:36,979 Hans what kind of sea states can you 367 00:15:40,299 --> 00:15:38,989 hand in maybe the weather gentleman can 368 00:15:42,519 --> 00:15:40,309 give us some sense of what the waves are 369 00:15:44,199 --> 00:15:42,529 wherever your drone ship is and I have a 370 00:15:45,729 --> 00:15:44,209 question for Mike after that yeah III 371 00:15:49,989 --> 00:15:45,739 don't know the sea state numbers but I 372 00:15:53,349 --> 00:15:49,999 heard the bass are currently four to ten 373 00:15:56,529 --> 00:15:53,359 feet and for the backup day I heard 374 00:15:58,659 --> 00:15:56,539 numbers up to 14 feet this is neither 375 00:16:01,869 --> 00:15:58,669 runs a problem for the autonomous space 376 00:16:07,059 --> 00:16:01,879 bar on ship its it's pretty heavy it's a 377 00:16:09,939 --> 00:16:07,069 it's a fairly heavy piece of metal so um 378 00:16:12,189 --> 00:16:09,949 and it has it has position correction 379 00:16:16,090 --> 00:16:12,199 for so it doesn't drift away it's 380 00:16:20,139 --> 00:16:16,100 actually very tight position control for 381 00:16:22,960 --> 00:16:20,149 my given given the the incident with the 382 00:16:24,609 --> 00:16:22,970 orbital spacecraft and you don't have 383 00:16:26,289 --> 00:16:24,619 them available for the rest of the year 384 00:16:28,539 --> 00:16:26,299 or at least until the netwo centaur 385 00:16:30,879 --> 00:16:28,549 flies at some point can you give us some 386 00:16:32,739 --> 00:16:30,889 sense of what how your your planning and 387 00:16:34,359 --> 00:16:32,749 strategy is for these resupply flights 388 00:16:35,769 --> 00:16:34,369 in the instance that you had a problem 389 00:16:37,689 --> 00:16:35,779 with SpaceX I mean I don't know if that 390 00:16:39,909 --> 00:16:37,699 makes any sense to you but obviously 391 00:16:41,649 --> 00:16:39,919 your single string now with supply ships 392 00:16:43,359 --> 00:16:41,659 I'm just wondering now that plays into 393 00:16:44,919 --> 00:16:43,369 your planning strategy for these 394 00:16:47,199 --> 00:16:44,929 downstream flights and how important it 395 00:16:50,469 --> 00:16:47,209 is for SpaceX to keep us steady cadence 396 00:16:52,569 --> 00:16:50,479 here so that's answering a couple ways 397 00:16:55,210 --> 00:16:52,579 long-term eventually we need to get the 398 00:16:57,369 --> 00:16:55,220 up mass back that we lost on the orbital 399 00:17:01,689 --> 00:16:57,379 flight but that doesn't have to occur 400 00:17:03,909 --> 00:17:01,699 this year we have made one change in our 401 00:17:07,269 --> 00:17:03,919 plan we we were trying to hold about a 402 00:17:09,220 --> 00:17:07,279 six-month protection on orbit so I had 403 00:17:11,409 --> 00:17:09,230 six months from one supply should flight 404 00:17:12,699 --> 00:17:11,419 to another we're probably going to 405 00:17:14,559 --> 00:17:12,709 dwindle that it's probably gonna doodle 406 00:17:17,199 --> 00:17:14,569 down to close to about four months in 407 00:17:18,519 --> 00:17:17,209 order to fly the research hard we want 408 00:17:20,949 --> 00:17:18,529 to do and all the other things that we 409 00:17:22,419 --> 00:17:20,959 want to set up and so we're flirting 410 00:17:24,639 --> 00:17:22,429 we're floating somewhere around that 411 00:17:27,100 --> 00:17:24,649 depending on the the consumable between 412 00:17:28,860 --> 00:17:27,110 four and six months so if something 413 00:17:30,870 --> 00:17:28,870 happened to SpaceX we'd have to 414 00:17:33,690 --> 00:17:30,880 you know figure out where we were and 415 00:17:35,690 --> 00:17:33,700 how quickly they could return to flight 416 00:17:38,970 --> 00:17:35,700 and then we would we would react 417 00:17:40,770 --> 00:17:38,980 accordingly but you know without your 418 00:17:44,370 --> 00:17:40,780 supply ships you can't go on 419 00:17:46,680 --> 00:17:44,380 indefinitely on orbit could you keep six 420 00:17:48,990 --> 00:17:46,690 people on board if you lost uh if SpaceX 421 00:17:50,850 --> 00:17:49,000 went down for any period of time depends 422 00:17:53,700 --> 00:17:50,860 on the period of time so we will attempt 423 00:17:55,830 --> 00:17:53,710 to keep the crew the crew has enough 424 00:17:57,299 --> 00:17:55,840 supplies including research to continue 425 00:17:59,610 --> 00:17:57,309 to work for somewhere between four and 426 00:18:01,290 --> 00:17:59,620 six months depending on what we did so 427 00:18:04,230 --> 00:18:01,300 the decision we'd have to make is how 428 00:18:07,590 --> 00:18:04,240 how quickly can can SpaceX 429 00:18:09,210 --> 00:18:07,600 get back up and then what can we do with 430 00:18:10,650 --> 00:18:09,220 our Russian colleagues with coordinating 431 00:18:13,020 --> 00:18:10,660 support they might supply which we'll 432 00:18:14,910 --> 00:18:13,030 talk to them about and then we'd have to 433 00:18:16,830 --> 00:18:14,920 look together about okay what's the 434 00:18:19,020 --> 00:18:16,840 right steps to take do we go ahead and 435 00:18:21,299 --> 00:18:19,030 let everybody go home until we're ready 436 00:18:25,020 --> 00:18:21,309 to resupply again or do we step down to 437 00:18:26,760 --> 00:18:25,030 three crew and and I suspect that's what 438 00:18:29,850 --> 00:18:26,770 we would do if we had to is we'd step 439 00:18:33,060 --> 00:18:29,860 down the three crew first but you know 440 00:18:35,610 --> 00:18:33,070 that the way we manage station is not to 441 00:18:37,410 --> 00:18:35,620 have to make those decisions immediately 442 00:18:38,640 --> 00:18:37,420 so we have quite a bit of resources on 443 00:18:40,290 --> 00:18:38,650 board we have quite a bit of time to 444 00:18:41,310 --> 00:18:40,300 work to the problem there's any number 445 00:18:43,110 --> 00:18:41,320 of problems that can be covered 446 00:18:45,660 --> 00:18:43,120 recovered from pretty quickly in flow 447 00:18:47,100 --> 00:18:45,670 and get right back to flight and then 448 00:18:48,810 --> 00:18:47,110 we'd spend a lot of time with SpaceX 449 00:18:51,120 --> 00:18:48,820 about priorities and things like that so 450 00:18:57,380 --> 00:18:51,130 there's you could work a number of 451 00:19:00,660 --> 00:18:57,390 scenarios and we have been madu next and 452 00:19:02,940 --> 00:19:00,670 and some of them you can stay on orbit 453 00:19:04,680 --> 00:19:02,950 for a while and others you may not be 454 00:19:06,330 --> 00:19:04,690 able to but in all cases we have plenty 455 00:19:07,560 --> 00:19:06,340 of time to decide what to do next figure 456 00:19:09,900 --> 00:19:07,570 out what we're really dealing with and 457 00:19:10,610 --> 00:19:09,910 then figure out how we want to react to 458 00:19:17,520 --> 00:19:10,620 it 459 00:19:18,960 --> 00:19:17,530 questions for Holmes um the first is can 460 00:19:20,970 --> 00:19:18,970 you just tell us what happened with the 461 00:19:24,240 --> 00:19:20,980 hot fire test last month that didn't 462 00:19:28,590 --> 00:19:24,250 work and also um considering that you 463 00:19:32,520 --> 00:19:28,600 SpaceX has already done two soft lands 464 00:19:35,250 --> 00:19:32,530 on water what is the challenge this time 465 00:19:37,410 --> 00:19:35,260 why why aren't you guys kind of 466 00:19:37,830 --> 00:19:37,420 expressing more confidence that this 467 00:19:41,430 --> 00:19:37,840 will work 468 00:19:42,890 --> 00:19:41,440 thanks yeah so the static fire the 469 00:19:45,750 --> 00:19:42,900 static fire was attached 470 00:19:48,300 --> 00:19:45,760 it we expected to be a little bit longer 471 00:19:49,970 --> 00:19:48,310 usually and that there are balls on the 472 00:19:53,940 --> 00:19:49,980 vehicle we clipped one of them 473 00:19:57,840 --> 00:19:53,950 it's we looked at the data and we were 474 00:20:01,260 --> 00:19:57,850 on the fence we decided just be cautious 475 00:20:03,690 --> 00:20:01,270 and repeat the static fire so that's 476 00:20:05,670 --> 00:20:03,700 what happened then I want to say on the 477 00:20:08,670 --> 00:20:05,680 19th a couple days later and by that 478 00:20:11,190 --> 00:20:08,680 time we pretty much boxed ourselves 479 00:20:16,170 --> 00:20:11,200 against Christmas and holiday season and 480 00:20:18,350 --> 00:20:16,180 so we decided to - I guess stand down 481 00:20:22,320 --> 00:20:18,360 and move everything into the next year 482 00:20:26,700 --> 00:20:22,330 personally I mean I came here a couple 483 00:20:29,430 --> 00:20:26,710 days ago the team is rested super you 484 00:20:31,470 --> 00:20:29,440 know sharp and and fresh to go and and I 485 00:20:35,280 --> 00:20:31,480 really think this was was a good move 486 00:20:36,810 --> 00:20:35,290 - to repeat the static fire and and give 487 00:20:40,440 --> 00:20:36,820 everybody a break before we continue 488 00:20:44,990 --> 00:20:40,450 with a rather busy on schedule for this 489 00:20:48,570 --> 00:20:45,000 year so I feel it was the right decision 490 00:20:51,720 --> 00:20:48,580 the second question was the how what's 491 00:20:53,550 --> 00:20:51,730 the difference yeah so in the past we 492 00:20:56,400 --> 00:20:53,560 lend we pretend that the ocean is a 493 00:20:58,140 --> 00:20:56,410 landing pad basically and landed soft on 494 00:21:00,930 --> 00:20:58,150 the end you write those landings were 495 00:21:03,750 --> 00:21:00,940 actually very successful they worked 496 00:21:08,330 --> 00:21:03,760 really nice there's obviously the ocean 497 00:21:11,820 --> 00:21:08,340 is not a platform and so so it didn't so 498 00:21:13,980 --> 00:21:11,830 we the fundamental difference is the 499 00:21:16,080 --> 00:21:13,990 limited size I think of the autonomous 500 00:21:20,490 --> 00:21:16,090 space but your own ship it's a it's very 501 00:21:24,390 --> 00:21:20,500 difficult to to to hit a platform of 502 00:21:26,370 --> 00:21:24,400 that size basically and when you look at 503 00:21:29,100 --> 00:21:26,380 it on the ground I think it's it's 504 00:21:30,990 --> 00:21:29,110 probably a very very big platform of big 505 00:21:37,080 --> 00:21:31,000 spaceport but if you look at it from I 506 00:21:39,870 --> 00:21:37,090 think almost 150 or so miles up in in in 507 00:21:42,930 --> 00:21:39,880 in sub orbit then it looks like a very 508 00:21:46,320 --> 00:21:42,940 very small place to land on so I think 509 00:21:50,150 --> 00:21:46,330 they'll tell the position accuracy of 510 00:21:54,060 --> 00:21:50,160 that is just them the primary challenge 511 00:21:56,520 --> 00:21:54,070 in general there's not a lot of room to 512 00:21:58,410 --> 00:21:56,530 maneuver everything has to be really 513 00:22:00,420 --> 00:21:58,420 fine and that's why I really really 514 00:22:02,280 --> 00:22:00,430 cautious I want to also point out I mean 515 00:22:05,040 --> 00:22:02,290 the focus clearly is on the main mission 516 00:22:09,330 --> 00:22:05,050 here cs5 cargo to the station 517 00:22:12,290 --> 00:22:09,340 and and so that's why we're very 518 00:22:19,590 --> 00:22:12,300 cautious and in terms of stage one 519 00:22:21,330 --> 00:22:19,600 landing success Jim Siegel I'm with the 520 00:22:24,510 --> 00:22:21,340 celebration news I have two questions 521 00:22:26,820 --> 00:22:24,520 one first for Mike Mikey and your 522 00:22:28,770 --> 00:22:26,830 opening comment you made a comment about 523 00:22:32,220 --> 00:22:28,780 the fact that the SpaceX will be 524 00:22:36,660 --> 00:22:32,230 delivering much-needed cargo and I was 525 00:22:39,240 --> 00:22:36,670 curious about what in particular is is 526 00:22:41,910 --> 00:22:39,250 needed at this point up at the space 527 00:22:44,520 --> 00:22:41,920 station is that food is that water is 528 00:22:47,610 --> 00:22:44,530 that other kinds of things that the 529 00:22:48,210 --> 00:22:47,620 equipment what would be most needed at 530 00:22:51,710 --> 00:22:48,220 this point 531 00:22:54,480 --> 00:22:51,720 well memory supply assumed that we had 532 00:22:57,240 --> 00:22:54,490 another vehicle with about two and a 533 00:22:59,190 --> 00:22:57,250 half metric tons and so as I said 534 00:23:02,880 --> 00:22:59,200 earlier we were building up to about a 535 00:23:04,950 --> 00:23:02,890 six month supply and and so now we've 536 00:23:06,960 --> 00:23:04,960 consumed some more food before we 537 00:23:09,330 --> 00:23:06,970 started adding so we're starting to 538 00:23:10,950 --> 00:23:09,340 erode into the four month that we don't 539 00:23:12,870 --> 00:23:10,960 want to erode into so that was part of 540 00:23:15,480 --> 00:23:12,880 it is to keep the consumables at a 541 00:23:17,580 --> 00:23:15,490 healthy level to give us wiggle room if 542 00:23:19,950 --> 00:23:17,590 should we need it the other is some 543 00:23:22,260 --> 00:23:19,960 spare parts oh we lost a few spare parts 544 00:23:24,870 --> 00:23:22,270 some of which we can't replace quickly 545 00:23:26,970 --> 00:23:24,880 and so we're we're finishing them up 546 00:23:28,890 --> 00:23:26,980 apply them on future flights and some of 547 00:23:31,830 --> 00:23:28,900 which we were able to get ready and get 548 00:23:32,760 --> 00:23:31,840 get on this flight and particularly we 549 00:23:34,080 --> 00:23:32,770 want to make sure we had all the 550 00:23:36,300 --> 00:23:34,090 hardware we needed on board for these 551 00:23:39,030 --> 00:23:36,310 EVs coming up as we start the first 552 00:23:43,260 --> 00:23:39,040 steps in reconfiguring the vehicle for 553 00:23:44,610 --> 00:23:43,270 for docking and Hans regarding the 554 00:23:48,060 --> 00:23:44,620 experiment that you were telling us 555 00:23:50,850 --> 00:23:48,070 about I presume that the idea here is to 556 00:23:54,180 --> 00:23:50,860 try to figure out how to be able to 557 00:23:58,290 --> 00:23:54,190 reuse the rocket since in the stage one 558 00:24:00,150 --> 00:23:58,300 and so on and this is an experiment I 559 00:24:03,000 --> 00:24:00,160 understand that so we're not going to we 560 00:24:04,950 --> 00:24:03,010 don't think that this is going to be 561 00:24:09,600 --> 00:24:04,960 very important aspect of this mission 562 00:24:10,050 --> 00:24:09,610 but on the other hand how important is 563 00:24:18,690 --> 00:24:10,060 the 564 00:24:21,450 --> 00:24:18,700 SpaceX's long-term strategy and trying 565 00:24:23,420 --> 00:24:21,460 to keep costs down yeah I think it's at 566 00:24:26,010 --> 00:24:23,430 the keyboard the keyboard is long-term 567 00:24:27,660 --> 00:24:26,020 obviously if you if you were to fly and 568 00:24:29,460 --> 00:24:27,670 throw the airplane away after every 569 00:24:33,120 --> 00:24:29,470 every trip you take it's going to be 570 00:24:36,270 --> 00:24:33,130 expensive and so if you carry this over 571 00:24:39,420 --> 00:24:36,280 to Rockets if you're able to reuse parts 572 00:24:42,960 --> 00:24:39,430 of the rocket first stage really and the 573 00:24:45,630 --> 00:24:42,970 key is actually reusability that is easy 574 00:24:48,060 --> 00:24:45,640 it does not involve taking the rocket 575 00:24:49,590 --> 00:24:48,070 apart and and replacing a lot of parts 576 00:24:51,210 --> 00:24:49,600 here and there and putting new engines 577 00:24:53,310 --> 00:24:51,220 on by that time you lost already 578 00:24:55,380 --> 00:24:53,320 basically but I think if you have 579 00:24:57,750 --> 00:24:55,390 reusability that you know even just 580 00:25:00,960 --> 00:24:57,760 limited for a number of flights that is 581 00:25:04,350 --> 00:25:00,970 in the airplane you know type category 582 00:25:06,870 --> 00:25:04,360 you inspect it that that is the long 583 00:25:11,520 --> 00:25:06,880 term vision I think that that largely 584 00:25:13,350 --> 00:25:11,530 alone drives into SpaceX and and and 585 00:25:17,160 --> 00:25:13,360 honestly you know if you if you if you 586 00:25:20,160 --> 00:25:17,170 do imagine that you can fly the stage 50 587 00:25:21,960 --> 00:25:20,170 times there will be that we costs 588 00:25:24,390 --> 00:25:21,970 associated with with recovering the 589 00:25:26,850 --> 00:25:24,400 stage but that's that is really the way 590 00:25:30,780 --> 00:25:26,860 to go and all that you get get cost on 591 00:25:32,700 --> 00:25:30,790 on launches down and yes we try 592 00:25:35,160 --> 00:25:32,710 something different in the past there's 593 00:25:39,510 --> 00:25:35,170 been different methods to to achieve 594 00:25:41,340 --> 00:25:39,520 reusability or landing so I feel like 595 00:25:44,310 --> 00:25:41,350 this is just another and another route 596 00:25:46,770 --> 00:25:44,320 that might actually it looked very it 597 00:25:51,390 --> 00:25:46,780 looks very promising actually I'm I'm 598 00:25:53,160 --> 00:25:51,400 gonna be super excited if this works but 599 00:25:55,860 --> 00:25:53,170 at the same time you know I I don't know 600 00:25:58,620 --> 00:25:55,870 distract from from you know the main 601 00:26:01,470 --> 00:25:58,630 mission I understand it's very important 602 00:26:04,020 --> 00:26:01,480 to get get cs5 into orbit actually much 603 00:26:06,260 --> 00:26:04,030 more important right now and we work on 604 00:26:10,980 --> 00:26:06,270 this long term goal you know 605 00:26:12,840 --> 00:26:10,990 continuously take a question over here 606 00:26:15,540 --> 00:26:12,850 then we're going to take questions from 607 00:26:17,850 --> 00:26:15,550 alan Boyle and James Dean before we 608 00:26:20,040 --> 00:26:17,860 check in with Jason Townsend who's been 609 00:26:21,720 --> 00:26:20,050 monitoring the hashtag ask NASA and 610 00:26:22,760 --> 00:26:21,730 after that we'll go to the phone bridge 611 00:26:24,620 --> 00:26:22,770 and then come back here 612 00:26:26,810 --> 00:26:24,630 questions hi there I'm Ian Bragg with 613 00:26:28,130 --> 00:26:26,820 NASA social questions for Hans curious 614 00:26:30,080 --> 00:26:28,140 what the control burns landing on the 615 00:26:31,670 --> 00:26:30,090 autonomous spaceport drone ship are 616 00:26:34,250 --> 00:26:31,680 using a significant amount of additional 617 00:26:35,570 --> 00:26:34,260 fuel and if so odds it's adding a lot 618 00:26:37,190 --> 00:26:35,580 more weight to the rocket and how is 619 00:26:40,070 --> 00:26:37,200 that different from previous launches 620 00:26:42,650 --> 00:26:40,080 you've done it's actually it's actually 621 00:26:45,140 --> 00:26:42,660 not that different from the other the 622 00:26:47,150 --> 00:26:45,150 simulated landings on the on the surface 623 00:26:49,910 --> 00:26:47,160 so it's very close it does use 624 00:26:52,210 --> 00:26:49,920 additional fuel on the overall sense you 625 00:26:55,010 --> 00:26:52,220 got to keep some fuel in the first stage 626 00:26:57,380 --> 00:26:55,020 for that maneuver but it's actually not 627 00:26:59,060 --> 00:26:57,390 that much and the there are some 628 00:27:01,880 --> 00:26:59,070 benefits you have the shake is largely 629 00:27:05,150 --> 00:27:01,890 empty so it's light after the the main 630 00:27:06,830 --> 00:27:05,160 burn after the ascent burn and we 631 00:27:10,820 --> 00:27:06,840 actually when we land we only have one 632 00:27:12,890 --> 00:27:10,830 engine on so so it's it's somewhat 633 00:27:15,440 --> 00:27:12,900 favorable in that case that the stage is 634 00:27:17,180 --> 00:27:15,450 actually it's a big structure there's no 635 00:27:19,400 --> 00:27:17,190 question it's a it's a pretty big 636 00:27:25,460 --> 00:27:19,410 structure but overall it is actually 637 00:27:27,620 --> 00:27:25,470 very light Ellen hi Hans I just wanted 638 00:27:31,310 --> 00:27:27,630 to kind of fill in some of the gaps that 639 00:27:34,280 --> 00:27:31,320 I had is there an abort sequences there 640 00:27:35,720 --> 00:27:34,290 in scenario where you would say let's do 641 00:27:37,670 --> 00:27:35,730 something different from the rocket or 642 00:27:39,230 --> 00:27:37,680 maybe let's tweak the rocket instead of 643 00:27:42,250 --> 00:27:39,240 trying to pull off the experiment and 644 00:27:44,540 --> 00:27:42,260 then is there going to be a real-time 645 00:27:47,210 --> 00:27:44,550 determination of how successful it was 646 00:27:49,010 --> 00:27:47,220 or do you need to wait for the videotape 647 00:27:51,250 --> 00:27:49,020 I don't understand the first part of 648 00:27:54,980 --> 00:27:51,260 your question and you this first part is 649 00:27:58,250 --> 00:27:54,990 you have the the first stage separation 650 00:28:00,110 --> 00:27:58,260 and then is there any scenario where you 651 00:28:02,810 --> 00:28:00,120 say we're not going to do the boost back 652 00:28:08,720 --> 00:28:02,820 it's automatic it's it's on sequence 653 00:28:11,360 --> 00:28:08,730 basically the the rocket goes its way so 654 00:28:13,850 --> 00:28:11,370 to speak it there there are decision 655 00:28:16,070 --> 00:28:13,860 points but the the rocket will nominally 656 00:28:18,800 --> 00:28:16,080 go through a timeline and perform the 657 00:28:24,020 --> 00:28:18,810 burns and maneuvers that that pointed to 658 00:28:26,060 --> 00:28:24,030 the autonomous space motor ownership so 659 00:28:31,220 --> 00:28:26,070 there's no decision there unless of 660 00:28:35,200 --> 00:28:31,230 Nvidia that's and the second the second 661 00:28:37,420 --> 00:28:35,210 question is well you know in real time 662 00:28:39,910 --> 00:28:37,430 worked I don't want to promise that 663 00:28:42,370 --> 00:28:39,920 frankly and the reason I want is because 664 00:28:46,240 --> 00:28:42,380 it depends on on Internet connectivity 665 00:28:49,210 --> 00:28:46,250 to satellite and and links that we don't 666 00:28:53,020 --> 00:28:49,220 always control and we've seen them work 667 00:28:55,060 --> 00:28:53,030 mostly but sometimes not so and we 668 00:28:57,610 --> 00:28:55,070 should we should know I have some 669 00:29:01,260 --> 00:28:57,620 indication but I really don't don't want 670 00:29:04,330 --> 00:29:01,270 to promise that the if you just rely on 671 00:29:08,800 --> 00:29:04,340 arranged assets here basically receiving 672 00:29:10,990 --> 00:29:08,810 antennas no you can see it from here it 673 00:29:12,160 --> 00:29:11,000 does work what happens to that stage how 674 00:29:18,670 --> 00:29:12,170 is it brought it's gonna be a huge 675 00:29:20,920 --> 00:29:18,680 celebration the stage will be brought 676 00:29:23,380 --> 00:29:20,930 back to port and and thoroughly 677 00:29:26,500 --> 00:29:23,390 inspected obviously that that a lot of 678 00:29:29,320 --> 00:29:26,510 lot of our future decisions depend on 679 00:29:31,930 --> 00:29:29,330 how well that stage comes back if 680 00:29:34,240 --> 00:29:31,940 there's any damage and how we could 681 00:29:38,620 --> 00:29:34,250 improve thermal protection and stuff 682 00:29:41,110 --> 00:29:38,630 like that yeah it will stay it will stay 683 00:29:46,810 --> 00:29:41,120 on the and the autonomous space pod tone 684 00:29:49,270 --> 00:29:46,820 ship James James Dean flora today Hans 685 00:29:51,280 --> 00:29:49,280 apologies but continuing on this theme 686 00:29:54,220 --> 00:29:51,290 with just some some additional 687 00:29:56,100 --> 00:29:54,230 clarifications disregarding the the 688 00:29:58,270 --> 00:29:56,110 differences in this one verse previous 689 00:30:00,670 --> 00:29:58,280 attempts or soft landings you know you 690 00:30:02,740 --> 00:30:00,680 have added some made some changes to the 691 00:30:05,800 --> 00:30:02,750 the booster with the fins right I just 692 00:30:07,270 --> 00:30:05,810 wondered you know how much of a 693 00:30:10,900 --> 00:30:07,280 difference do you expect that to be I 694 00:30:15,820 --> 00:30:10,910 mean 5050 odds actually sounded pretty 695 00:30:18,250 --> 00:30:15,830 good to me for this first time you 696 00:30:21,340 --> 00:30:18,260 referenced the may I'll just start there 697 00:30:22,930 --> 00:30:21,350 if I can yeah so you're right we added 698 00:30:24,340 --> 00:30:22,940 we added good fins to the vehicle 699 00:30:28,900 --> 00:30:24,350 they're visible on the outside and they 700 00:30:32,050 --> 00:30:28,910 fold out I guess like five minutes 701 00:30:35,770 --> 00:30:32,060 roughly into flight the the grid fins 702 00:30:39,700 --> 00:30:35,780 give us more range on the on the down 703 00:30:41,710 --> 00:30:39,710 part of the the trajectory and and they 704 00:30:44,050 --> 00:30:41,720 allow us to keep the vehicle stable so 705 00:30:47,190 --> 00:30:44,060 they save poor parent which we obviously 706 00:30:49,770 --> 00:30:47,200 need for the landing itself so 707 00:30:52,320 --> 00:30:49,780 so that is obviously one part of the 708 00:30:54,780 --> 00:30:52,330 uncertainty that we have we've done if 709 00:30:57,390 --> 00:30:54,790 done analysis we can test but ultimately 710 00:30:59,760 --> 00:30:57,400 you need to fly test to verify how 711 00:31:02,220 --> 00:30:59,770 effective are those fins how well do 712 00:31:04,380 --> 00:31:02,230 their work do they maintain stability in 713 00:31:07,110 --> 00:31:04,390 terms of roll pitch and yaw on the 714 00:31:10,890 --> 00:31:07,120 vehicle and all these things it is an 715 00:31:14,760 --> 00:31:10,900 experiment to some extent 50 percent and 716 00:31:16,350 --> 00:31:14,770 now it's so suddenly for for the type of 717 00:31:20,010 --> 00:31:16,360 experiment I would agree with you it's 718 00:31:23,570 --> 00:31:20,020 actually not too bad but then obviously 719 00:31:32,280 --> 00:31:23,580 the main mission is so so much more and 720 00:31:34,950 --> 00:31:32,290 I ability competed pales against that so 721 00:31:37,980 --> 00:31:34,960 you reference the stability of the 722 00:31:40,080 --> 00:31:37,990 autonomous drone ship and the lightness 723 00:31:42,150 --> 00:31:40,090 of the booster actually I meant 724 00:31:44,640 --> 00:31:42,160 stability on the on the on the first 725 00:31:47,910 --> 00:31:44,650 stage itself I'm sorry I'm sorry mostly 726 00:31:51,750 --> 00:31:47,920 mostly in terms of roll pitch and yaw on 727 00:31:53,280 --> 00:31:51,760 the on the on the stage one itself it's 728 00:31:55,110 --> 00:31:53,290 only this is only for the way back 729 00:31:56,790 --> 00:31:55,120 basically it's not for the way for the 730 00:31:59,730 --> 00:31:56,800 way up for the ascent part nothing 731 00:32:02,790 --> 00:31:59,740 changed this will look like the last 732 00:32:05,100 --> 00:32:02,800 launch the the ship itself just in 733 00:32:06,510 --> 00:32:05,110 reference to waves and so forth you 734 00:32:08,010 --> 00:32:06,520 mentioned it's pretty stable 735 00:32:10,320 --> 00:32:08,020 yeah the stage is pretty light if you 736 00:32:12,000 --> 00:32:10,330 stick the landing yes I mean will the 737 00:32:14,580 --> 00:32:12,010 booster literally just stand there or 738 00:32:18,600 --> 00:32:14,590 could it be blown over by a gust of wind 739 00:32:20,190 --> 00:32:18,610 or also curious if if you had a hard 740 00:32:28,320 --> 00:32:20,200 landing rather than a soft landing would 741 00:32:33,410 --> 00:32:28,330 that be bad for ya it's which would it 742 00:32:39,720 --> 00:32:37,140 yeah Lenny has to be perfect in order to 743 00:32:43,500 --> 00:32:39,730 actually just stand there and and be 744 00:32:46,650 --> 00:32:43,510 safe on the ship the shape is pretty big 745 00:32:49,020 --> 00:32:46,660 so I don't expect waves unless they're 746 00:32:52,020 --> 00:32:49,030 really large to have any impact on the 747 00:32:55,170 --> 00:32:52,030 vehicle we our analysis indicates the 748 00:32:56,850 --> 00:32:55,180 the first stage will stand securely it 749 00:32:59,670 --> 00:32:56,860 will then go actually when it lands it 750 00:33:03,240 --> 00:32:59,680 goes to a saving sequence the 751 00:33:05,700 --> 00:33:03,250 the boat nearby that will get closer 752 00:33:07,770 --> 00:33:05,710 than has control of the stage so they 753 00:33:11,130 --> 00:33:07,780 can bent the stage they can verify the 754 00:33:14,310 --> 00:33:11,140 stage is safe to go everything has been 755 00:33:16,230 --> 00:33:14,320 saved and so we have a operational 756 00:33:18,480 --> 00:33:16,240 concept of operations basically how to 757 00:33:20,880 --> 00:33:18,490 secure the stage then on the boat and 758 00:33:23,270 --> 00:33:20,890 and tie it down and make sure that on 759 00:33:27,540 --> 00:33:23,280 the trip back to port nothing happens 760 00:33:30,120 --> 00:33:27,550 and lastly I know a lot depends on 761 00:33:32,850 --> 00:33:30,130 exactly what happens but based on 762 00:33:35,340 --> 00:33:32,860 whatever plan you have nominally or sort 763 00:33:37,799 --> 00:33:35,350 of optimistically how many times you 764 00:33:40,260 --> 00:33:37,809 expect to you know if you're able to 765 00:33:42,570 --> 00:33:40,270 pull off the landing mm-hmm whenever 766 00:33:43,980 --> 00:33:42,580 that is how often do you expect to try 767 00:33:48,419 --> 00:33:43,990 to do that before you might be ready to 768 00:33:50,040 --> 00:33:48,429 move to a landing on land you know this 769 00:33:52,130 --> 00:33:50,050 actually depends partly on the manifest 770 00:33:55,320 --> 00:33:52,140 there might be situations where the 771 00:33:57,060 --> 00:33:55,330 where the drone ship landing is more 772 00:33:58,860 --> 00:33:57,070 favorable in terms of propellant and 773 00:34:00,720 --> 00:33:58,870 there might be other situations where it 774 00:34:05,040 --> 00:34:00,730 might be favorable or possible to get 775 00:34:08,610 --> 00:34:05,050 back to land so it really depends on the 776 00:34:13,350 --> 00:34:08,620 other mission itself if I recall 777 00:34:16,500 --> 00:34:13,360 correctly that drone ship will be active 778 00:34:18,720 --> 00:34:16,510 for the next couple launches then range 779 00:34:20,399 --> 00:34:18,730 safety have you committed to trying a 780 00:34:23,820 --> 00:34:20,409 certain number of times to before the 781 00:34:25,740 --> 00:34:23,830 nodes come back to land no no I mean 782 00:34:29,250 --> 00:34:25,750 it's it's it's certainly safer um the 783 00:34:31,350 --> 00:34:29,260 way we do it right now and range safety 784 00:34:33,780 --> 00:34:31,360 is pretty happy about that too 785 00:34:37,530 --> 00:34:33,790 so it's a good it's a good it's a good 786 00:34:39,690 --> 00:34:37,540 test before you get back to land okay 787 00:34:42,510 --> 00:34:39,700 Jason Townsend has been monitoring 788 00:34:44,550 --> 00:34:42,520 social media questions for people who 789 00:34:46,889 --> 00:34:44,560 are watching online and using the 790 00:34:48,869 --> 00:34:46,899 hashtag ask NASA Jason do you have any 791 00:34:50,520 --> 00:34:48,879 any questions for us indeed there's 792 00:34:52,290 --> 00:34:50,530 actually several here this first one 793 00:34:54,930 --> 00:34:52,300 comes from Twitter user Anthony who's 794 00:34:56,520 --> 00:34:54,940 asking this is for Hans here if the 795 00:34:59,120 --> 00:34:56,530 first-stage landing is successful how 796 00:35:01,590 --> 00:34:59,130 long will it be before we see video and 797 00:35:05,520 --> 00:35:01,600 dovetailing with that philip asks when 798 00:35:08,010 --> 00:35:05,530 will will we know the result live so the 799 00:35:12,030 --> 00:35:08,020 second question results live probably 800 00:35:18,030 --> 00:35:15,180 if we know the control then I'm pretty 801 00:35:20,610 --> 00:35:18,040 sure it's gonna be out pretty soon yeah 802 00:35:25,920 --> 00:35:20,620 but we might be you might not know it 803 00:35:28,770 --> 00:35:25,930 immediately and in terms of video I want 804 00:35:30,810 --> 00:35:28,780 to say if it goes well by the end of the 805 00:35:32,310 --> 00:35:30,820 day maybe something like that it takes 806 00:35:34,470 --> 00:35:32,320 it takes a cut it takes a while to 807 00:35:36,990 --> 00:35:34,480 transmit the video back and and that's 808 00:35:41,970 --> 00:35:37,000 another thing where the link has to work 809 00:35:45,570 --> 00:35:41,980 so it might be a couple hours they there 810 00:35:51,240 --> 00:35:45,580 too we work as hard as we can to get 811 00:35:53,160 --> 00:35:51,250 this done but uh wonderful next question 812 00:35:55,530 --> 00:35:53,170 here is for is from a Twitter user 813 00:35:57,510 --> 00:35:55,540 Douglas who asks what a single engine 814 00:35:59,520 --> 00:35:57,520 failure prevent the first stage recovery 815 00:36:03,810 --> 00:35:59,530 even if you could push dravite dragon 816 00:36:05,430 --> 00:36:03,820 onto orbit it depends so um 817 00:36:06,930 --> 00:36:05,440 it depends on the engine that fails if 818 00:36:11,490 --> 00:36:06,940 it happens to be the engine we need for 819 00:36:14,070 --> 00:36:11,500 landing I believe that I did want to 820 00:36:15,900 --> 00:36:14,080 point out that actually has they would 821 00:36:17,940 --> 00:36:15,910 probably have no bearing at all for 822 00:36:21,600 --> 00:36:17,950 photo Ragan if he if he loses the 823 00:36:24,480 --> 00:36:21,610 landing engine we need for the for the 824 00:36:27,600 --> 00:36:24,490 for the stage landing sequence we need 825 00:36:32,700 --> 00:36:27,610 three three specific engines currently 826 00:36:33,960 --> 00:36:32,710 if one of those engines would fail at 827 00:36:35,880 --> 00:36:33,970 the center engine would fail that would 828 00:36:38,010 --> 00:36:35,890 certainly be a problem but I'm not sure 829 00:36:42,090 --> 00:36:38,020 about the other two that might you might 830 00:36:45,779 --> 00:36:42,100 be able to pull this off anyways the 831 00:36:49,900 --> 00:36:48,279 this next question comes from a Twitter 832 00:36:52,089 --> 00:36:49,910 user Anthony who asked at what altitude 833 00:36:58,059 --> 00:36:52,099 and speed do you expect the grid fins to 834 00:36:59,499 --> 00:36:58,069 deploy they deploy og I know the time I 835 00:37:01,359 --> 00:36:59,509 looked at the time but I really didn't 836 00:37:04,150 --> 00:37:01,369 check the altitude it's it's way out in 837 00:37:09,279 --> 00:37:04,160 the outside the atmosphere so it's 838 00:37:12,339 --> 00:37:09,289 before we enter wonderful next question 839 00:37:13,900 --> 00:37:12,349 comes from John on Twitter who asks did 840 00:37:15,579 --> 00:37:13,910 the drone ship move to the landing zone 841 00:37:17,259 --> 00:37:15,589 on its own 842 00:37:18,489 --> 00:37:17,269 was there a crew on board the drone ship 843 00:37:22,480 --> 00:37:18,499 while it was moving to the landing zone 844 00:37:24,640 --> 00:37:22,490 I think so well actually I don't know 845 00:37:25,839 --> 00:37:24,650 that should be correct I mean um I I 846 00:37:28,749 --> 00:37:25,849 don't know the details how we got the 847 00:37:32,230 --> 00:37:28,759 drone ship there I know there's another 848 00:37:33,970 --> 00:37:32,240 boat with crew and the drone ship I'm 849 00:37:36,549 --> 00:37:33,980 not sure if there's any quarters on it 850 00:37:39,099 --> 00:37:36,559 or not I don't think so 851 00:37:41,739 --> 00:37:39,109 wonderful and this last question here is 852 00:37:43,569 --> 00:37:41,749 from Brent who asks how do the people at 853 00:37:51,279 --> 00:37:43,579 NASA feel about SpaceX trying to land 854 00:37:53,470 --> 00:37:51,289 the first stage I can't go to me okay 855 00:38:01,749 --> 00:37:53,480 the people at NASA are really interested 856 00:38:04,420 --> 00:38:01,759 in that I I don't know I mean it's 857 00:38:05,979 --> 00:38:04,430 I guess NASA wants to make sure that it 858 00:38:08,049 --> 00:38:05,989 doesn't get attention away from the main 859 00:38:11,680 --> 00:38:08,059 mission I want to say that that's just 860 00:38:14,140 --> 00:38:11,690 and honestly I see that I have the same 861 00:38:17,609 --> 00:38:14,150 same interest I want to make sure that 862 00:38:20,019 --> 00:38:17,619 the Cirrus 5 mission works perfectly and 863 00:38:22,150 --> 00:38:20,029 there's no impact to the mission at all 864 00:38:24,970 --> 00:38:22,160 that's the main thing so Han said it 865 00:38:26,920 --> 00:38:24,980 very well we're extremely interested in 866 00:38:30,370 --> 00:38:26,930 the success of this flight in terms of 867 00:38:33,339 --> 00:38:30,380 getting cargo to ISS but as an agency 868 00:38:35,769 --> 00:38:33,349 we're also extremely proud of our 869 00:38:38,019 --> 00:38:35,779 affiliation with with SpaceX and very 870 00:38:40,329 --> 00:38:38,029 excited about the steps they take to 871 00:38:43,299 --> 00:38:40,339 further Space Flight in general and 872 00:38:45,729 --> 00:38:43,309 reduce the cost of spaceflight so this 873 00:38:49,089 --> 00:38:45,739 exciting time from our perspective as 874 00:38:50,890 --> 00:38:49,099 well okay we're going to go to the phone 875 00:38:53,739 --> 00:38:50,900 bridge now where we have two callers on 876 00:38:55,029 --> 00:38:53,749 hold first let's go to Jason Davis from 877 00:38:58,310 --> 00:38:55,039 the Planetary Society 878 00:39:00,500 --> 00:38:58,320 are you there Jason yeah thank you 879 00:39:03,290 --> 00:39:00,510 this is for Hans again all about the 880 00:39:07,070 --> 00:39:03,300 Bart I wanted to know if you have a 881 00:39:09,290 --> 00:39:07,080 precise landing coordinates for his 882 00:39:12,020 --> 00:39:09,300 barge it looked like it was about 200 883 00:39:14,930 --> 00:39:12,030 miles east of Jacksonville possibly and 884 00:39:16,340 --> 00:39:14,940 then secondly I wanted to see if you'd 885 00:39:19,730 --> 00:39:16,350 be willing to say how much the 886 00:39:21,320 --> 00:39:19,740 autonomous drone cost thank you okay on 887 00:39:26,120 --> 00:39:21,330 the first one the first my question oh 888 00:39:27,010 --> 00:39:26,130 my comment is stay away I really mean 889 00:39:30,200 --> 00:39:27,020 that 890 00:39:32,030 --> 00:39:30,210 and on the second one I don't know the 891 00:39:33,500 --> 00:39:32,040 cost frankly it's actually I want to 892 00:39:36,170 --> 00:39:33,510 point out it's not a barrace barge has 893 00:39:42,680 --> 00:39:36,180 no no propulsion this this vehicle has 894 00:39:44,510 --> 00:39:42,690 trusters and so it's a drone ship okay 895 00:39:46,750 --> 00:39:44,520 still on the phone bridge Michael 896 00:39:50,030 --> 00:39:46,760 Balfour from Popular Mechanics 897 00:39:52,400 --> 00:39:50,040 hi there it's good to be here thank you 898 00:39:55,310 --> 00:39:52,410 for answering these questions about the 899 00:39:56,840 --> 00:39:55,320 drone ship can you give us a rough you 900 00:39:59,030 --> 00:39:56,850 know just how far out it's going to be 901 00:40:01,040 --> 00:39:59,040 from the Florida coast it's not the 902 00:40:02,540 --> 00:40:01,050 actual coordinates and also I wanted to 903 00:40:04,609 --> 00:40:02,550 just verify that you said it was about 904 00:40:06,290 --> 00:40:04,619 nine minutes after launch that it's 905 00:40:08,000 --> 00:40:06,300 supposed to land the first stage will 906 00:40:10,849 --> 00:40:08,010 land on the barge is that I mean on the 907 00:40:13,130 --> 00:40:10,859 drum ship is that right yes that's 908 00:40:14,870 --> 00:40:13,140 correct it's it's the noumenal time line 909 00:40:17,599 --> 00:40:14,880 shuts the engine down right around nine 910 00:40:19,580 --> 00:40:17,609 nine minutes and again that's just just 911 00:40:23,510 --> 00:40:19,590 a little tad before the second stage 912 00:40:26,470 --> 00:40:23,520 shuts down and I on purpose did not look 913 00:40:29,900 --> 00:40:26,480 exactly at the location I know it's a 914 00:40:33,880 --> 00:40:29,910 it's a couple hundred miles out in the 915 00:40:36,320 --> 00:40:33,890 in the ocean to be safe basically but I 916 00:40:40,460 --> 00:40:36,330 don't know the exact the exact location 917 00:40:43,849 --> 00:40:40,470 unfortunately okay back here for 918 00:40:44,810 --> 00:40:43,859 questions Phil I feel heating foxnews 919 00:40:47,450 --> 00:40:44,820 Hans 920 00:40:49,190 --> 00:40:47,460 I'd like to return back to the landing 921 00:40:54,080 --> 00:40:49,200 on the autonomous drone ship if you 922 00:40:56,420 --> 00:40:54,090 don't mind first of all is it sitting in 923 00:40:59,450 --> 00:40:56,430 the spot right now where you're hoping 924 00:41:01,760 --> 00:40:59,460 the rocket lands or is it actually going 925 00:41:05,540 --> 00:41:01,770 to adjust at all tomorrow it picks a 926 00:41:09,590 --> 00:41:05,550 spot and and it holds the spot it holds 927 00:41:11,990 --> 00:41:09,600 it very tightly Elon Musk who said the 928 00:41:14,180 --> 00:41:12,000 whole idea of not trashing the rocket 929 00:41:16,880 --> 00:41:14,190 into the ocean yeah but doing this 930 00:41:20,359 --> 00:41:16,890 reusability like is that you know akin 931 00:41:22,630 --> 00:41:20,369 to not buying a brand-new 747 and 932 00:41:24,890 --> 00:41:22,640 throwing it away after one flight so 933 00:41:28,670 --> 00:41:24,900 ticket into the future where this has 934 00:41:30,560 --> 00:41:28,680 proven successfully what we will be 935 00:41:33,440 --> 00:41:30,570 looking at is the future of space 936 00:41:36,310 --> 00:41:33,450 exploration with rockets that it could 937 00:41:39,740 --> 00:41:36,320 possibly land on the launch pad day of 938 00:41:41,420 --> 00:41:39,750 riri stack and take off again sort of 939 00:41:42,140 --> 00:41:41,430 like a commercial aircraft I mean what 940 00:41:43,790 --> 00:41:42,150 what could it be 941 00:41:46,310 --> 00:41:43,800 that's they think that is the the vision 942 00:41:48,770 --> 00:41:46,320 ultimately to make this more like an 943 00:41:50,900 --> 00:41:48,780 aircraft operation where the stage comes 944 00:41:55,250 --> 00:41:50,910 back gets 945 00:41:56,780 --> 00:41:55,260 minimal service fundamentally if you 946 00:42:00,650 --> 00:41:56,790 look at the aircraft industry which is 947 00:42:02,120 --> 00:42:00,660 extremely a well-oiled machine by now 948 00:42:04,190 --> 00:42:02,130 just simply because they have so many 949 00:42:06,880 --> 00:42:04,200 operations and if you can get the number 950 00:42:09,349 --> 00:42:06,890 of operations up in the space industry 951 00:42:12,230 --> 00:42:09,359 that that basically is our our our 952 00:42:14,720 --> 00:42:12,240 vision our goal to have as many launches 953 00:42:16,280 --> 00:42:14,730 as possible to make sure that we fully 954 00:42:19,910 --> 00:42:16,290 understand what happens on the way up 955 00:42:22,609 --> 00:42:19,920 and down and address whatever needs to 956 00:42:26,120 --> 00:42:22,619 be addressed but not more and basically 957 00:42:27,109 --> 00:42:26,130 drive the cost cost down over long long 958 00:42:30,410 --> 00:42:27,119 range I mean this would have an impact 959 00:42:34,160 --> 00:42:30,420 on the entire industry if you you know 960 00:42:35,510 --> 00:42:34,170 for a moment assume this would be what 961 00:42:37,430 --> 00:42:35,520 you said like one launch per day or 962 00:42:41,240 --> 00:42:37,440 something like that or even more you 963 00:42:43,430 --> 00:42:41,250 will fly spacecraft that could there 964 00:42:46,070 --> 00:42:43,440 wouldn't be that expensive anymore you 965 00:42:50,480 --> 00:42:46,080 would take more risks and you might have 966 00:42:52,880 --> 00:42:50,490 a week of supply on the station so I 967 00:42:54,890 --> 00:42:52,890 think I think if this would work out it 968 00:42:56,030 --> 00:42:54,900 would have a tremendous impact on the on 969 00:42:58,310 --> 00:42:56,040 the industry that I haven't really 970 00:43:01,310 --> 00:42:58,320 thought through personally I'm pretty 971 00:43:04,560 --> 00:43:01,320 sure Elon did so 972 00:43:06,480 --> 00:43:04,570 yeah go ahead Stuart money interspace 973 00:43:09,420 --> 00:43:06,490 net and my question on the same subject 974 00:43:11,790 --> 00:43:09,430 is for Hans two questions actually one 975 00:43:14,100 --> 00:43:11,800 on the return effort will the center 976 00:43:16,730 --> 00:43:14,110 engine be burning continuously or are 977 00:43:20,460 --> 00:43:16,740 there three separate ignition events 978 00:43:21,930 --> 00:43:20,470 it's three separate ignition events okay 979 00:43:25,320 --> 00:43:21,940 so if you can't the assent to it 980 00:43:26,580 --> 00:43:25,330 actually then for I and in the event you 981 00:43:30,300 --> 00:43:26,590 are successful will you be coming back 982 00:43:31,980 --> 00:43:30,310 to Jacksonville or right down Main 983 00:43:39,450 --> 00:43:31,990 Street here into the turning base I 984 00:43:41,010 --> 00:43:39,460 think it's excellent thank you okay hold 985 00:43:45,920 --> 00:43:41,020 off for a second I'll let Jimmy get 986 00:43:52,560 --> 00:43:49,830 Irene Klotz with Reuters for Mike is 987 00:43:54,480 --> 00:43:52,570 there anything specifically that had to 988 00:43:57,360 --> 00:43:54,490 be added on to a dragon after the 989 00:43:59,400 --> 00:43:57,370 problem with the Antares as you 990 00:44:02,130 --> 00:43:59,410 mentioned some spacewalk equipment I 991 00:44:05,250 --> 00:44:02,140 think and for Hans um on another off 992 00:44:07,710 --> 00:44:05,260 topic since you're being very open today 993 00:44:12,180 --> 00:44:07,720 can you give us an update on Falcon 994 00:44:14,790 --> 00:44:12,190 Heavy flight this year and just the 995 00:44:18,210 --> 00:44:14,800 overall SpaceX manifests for the year 996 00:44:21,000 --> 00:44:18,220 Thanks so to answer your question we 997 00:44:24,240 --> 00:44:21,010 made some changes for the life of me 998 00:44:26,580 --> 00:44:24,250 that was before Christmas holiday but I 999 00:44:28,680 --> 00:44:26,590 can get that for you but we did have to 1000 00:44:30,690 --> 00:44:28,690 rearrange the manifest our SpaceX 1001 00:44:33,360 --> 00:44:30,700 friends were very accommodating there 1002 00:44:36,630 --> 00:44:33,370 were some items we we put off there were 1003 00:44:39,690 --> 00:44:36,640 some we took off a what we call a Norris 1004 00:44:41,280 --> 00:44:39,700 tank nitrogen oxygen resupply tank we 1005 00:44:43,680 --> 00:44:41,290 figured out from a logistic standpoint 1006 00:44:46,650 --> 00:44:43,690 we didn't need that tank it was gonna 1007 00:44:48,510 --> 00:44:46,660 fly with oxygen on board and that freed 1008 00:44:50,220 --> 00:44:48,520 up room to bring some other supplies but 1009 00:44:51,540 --> 00:44:50,230 specifically we would put on I forgotten 1010 00:45:03,360 --> 00:44:51,550 now but I can get that for you and 1011 00:45:06,200 --> 00:45:03,370 supply it through these guys okay so the 1012 00:45:09,270 --> 00:45:06,210 manufactures busy on the bright side 1013 00:45:12,300 --> 00:45:09,280 unlike this this will now include more 1014 00:45:13,230 --> 00:45:12,310 launch sites so Vandenberg will be 1015 00:45:17,340 --> 00:45:13,240 they'll be more 1016 00:45:21,090 --> 00:45:17,350 if you will see the the next mission is 1017 00:45:24,590 --> 00:45:21,100 a mission called discover and it's 1018 00:45:29,220 --> 00:45:24,600 actually currently at the end of January 1019 00:45:31,980 --> 00:45:29,230 there will be dragon missions dragon 1020 00:45:32,640 --> 00:45:31,990 crew dragon missions rather like the the 1021 00:45:35,760 --> 00:45:32,650 pad abort 1022 00:45:39,630 --> 00:45:35,770 for example heavy I don't know 1023 00:45:41,190 --> 00:45:39,640 where we are currently and how how 1024 00:45:43,650 --> 00:45:41,200 everything is coming together but I know 1025 00:45:46,020 --> 00:45:43,660 that the significant part of the company 1026 00:45:48,990 --> 00:45:46,030 is working on Falcon Heavy and trying to 1027 00:45:50,730 --> 00:45:49,000 get it out for the first flight but I 1028 00:45:57,090 --> 00:45:50,740 really don't have an update on the on 1029 00:45:58,920 --> 00:45:57,100 the actual launch date associated press 1030 00:46:00,960 --> 00:45:58,930 with two questions quick one for Hans 1031 00:46:03,210 --> 00:46:00,970 what will be the peak altitude of the 1032 00:46:04,590 --> 00:46:03,220 first stage I think you mentioned 150 1033 00:46:05,910 --> 00:46:04,600 miles but I wasn't sure if that's as 1034 00:46:10,680 --> 00:46:05,920 high as it will go and then I had a 1035 00:46:12,500 --> 00:46:10,690 question for Mike I don't that's the 1036 00:46:16,920 --> 00:46:12,510 that's actually usually the altitude 1037 00:46:18,960 --> 00:46:16,930 roughly but and I don't think the burns 1038 00:46:20,550 --> 00:46:18,970 reduce the altitude that much so it's 1039 00:46:22,800 --> 00:46:20,560 probably a little bit lower than what I 1040 00:46:24,410 --> 00:46:22,810 quoted here I had to look up the numbers 1041 00:46:27,540 --> 00:46:24,420 can I can get back to you on that 1042 00:46:30,480 --> 00:46:27,550 thank you and for Mike you mentioned 1043 00:46:32,430 --> 00:46:30,490 that you plan to fly ultimately more 1044 00:46:33,270 --> 00:46:32,440 when your missions and would you 1045 00:46:36,270 --> 00:46:33,280 envision those being 1046 00:46:38,970 --> 00:46:36,280 back-to-back-to-back how many more over 1047 00:46:42,630 --> 00:46:38,980 hum you know how many do you envision 1048 00:46:43,830 --> 00:46:42,640 and do you have a stampede of astronauts 1049 00:46:49,320 --> 00:46:43,840 who are willing to go up there for a 1050 00:46:50,610 --> 00:46:49,330 solid year oh that's a that's a loaded 1051 00:46:53,370 --> 00:46:50,620 question so I'll stay away from the 1052 00:46:57,300 --> 00:46:53,380 Stampede astronauts but the the answer 1053 00:47:00,180 --> 00:46:57,310 question is from a u.s. Life Sciences 1054 00:47:01,650 --> 00:47:00,190 perspective they have come to us and 1055 00:47:05,730 --> 00:47:01,660 said they thought it would be beneficial 1056 00:47:07,290 --> 00:47:05,740 to have 12 one-year subjects we have 1057 00:47:11,730 --> 00:47:07,300 been talking to our partners about when 1058 00:47:13,440 --> 00:47:11,740 the next one could occur but we haven't 1059 00:47:15,620 --> 00:47:13,450 agreed on that yet so by definition 1060 00:47:18,630 --> 00:47:15,630 because of where we are in the cycle of 1061 00:47:21,630 --> 00:47:18,640 selecting crews certainly the next 1062 00:47:24,810 --> 00:47:21,640 flight after Scott and Mikkel return 1063 00:47:26,850 --> 00:47:24,820 home won't be one of those it may very 1064 00:47:28,380 --> 00:47:26,860 well wait all the way until we get 1065 00:47:29,760 --> 00:47:28,390 the Commercial Crew vehicle where we 1066 00:47:31,830 --> 00:47:29,770 have more seats that we could dedicate 1067 00:47:34,260 --> 00:47:31,840 to it but we're trying to decide that 1068 00:47:37,770 --> 00:47:34,270 that very question now but as a 1069 00:47:42,060 --> 00:47:37,780 community even outside the US the life 1070 00:47:44,480 --> 00:47:42,070 scientists folks across the partnership 1071 00:47:46,620 --> 00:47:44,490 agree that more subjects would be good 1072 00:47:48,450 --> 00:47:46,630 they they're trying to get enough 1073 00:47:50,430 --> 00:47:48,460 subjects to know whether or not there is 1074 00:47:52,740 --> 00:47:50,440 whether or not we've reached equilibrium 1075 00:47:54,690 --> 00:47:52,750 at six months or whether there's enough 1076 00:47:59,520 --> 00:47:54,700 changes that tells you you need to do 1077 00:48:03,660 --> 00:47:59,530 more to know if you can go further than 1078 00:48:06,900 --> 00:48:03,670 then then one year on orbit so the the 1079 00:48:08,730 --> 00:48:06,910 whole point of the subjects even though 1080 00:48:11,400 --> 00:48:08,740 statistically speaking twelve isn't a 1081 00:48:14,100 --> 00:48:11,410 huge number it's enough to see if the 1082 00:48:16,290 --> 00:48:14,110 curve is going to change and if you can 1083 00:48:17,400 --> 00:48:16,300 figure out the curves gonna gonna change 1084 00:48:19,850 --> 00:48:17,410 or whether or not you've kind of 1085 00:48:21,960 --> 00:48:19,860 stabilized then you'll feel good about 1086 00:48:25,590 --> 00:48:21,970 decisions you make in the future for how 1087 00:48:29,760 --> 00:48:25,600 many months you can fly based on the 1088 00:48:31,620 --> 00:48:29,770 evidence from station don't just a very 1089 00:48:33,360 --> 00:48:31,630 quick question for Hans how long does 1090 00:48:35,430 --> 00:48:33,370 safing last before the crew can get on 1091 00:48:36,870 --> 00:48:35,440 board the the drone ship and I was 1092 00:48:39,240 --> 00:48:36,880 wondering you know I assume the LOX just 1093 00:48:40,830 --> 00:48:39,250 boils off in vents I wasn't sure about 1094 00:48:42,090 --> 00:48:40,840 the RP one is that whatever residual 1095 00:48:43,710 --> 00:48:42,100 amounts there is it just stay in the 1096 00:48:46,800 --> 00:48:43,720 tank just stays in the tank yeah it's 1097 00:48:50,370 --> 00:48:46,810 like like any other airplane basically 1098 00:48:54,360 --> 00:48:50,380 and that um it set the order of maybe 1099 00:48:57,460 --> 00:48:54,370 one or two hours let's take a question 1100 00:49:02,569 --> 00:49:00,079 my name is Brittany Kraft I'm with the 1101 00:49:05,569 --> 00:49:02,579 NASA social attendees and I was curious 1102 00:49:07,880 --> 00:49:05,579 if SpaceX will be considered at Wallops 1103 00:49:11,180 --> 00:49:07,890 Island after everything gets back up and 1104 00:49:17,779 --> 00:49:11,190 running you mean as a launch site 1105 00:49:19,670 --> 00:49:17,789 yes so we did originally trade launch 1106 00:49:22,880 --> 00:49:19,680 sites and we made the decision at the 1107 00:49:26,599 --> 00:49:22,890 time that we go to the Cape and to 1108 00:49:31,730 --> 00:49:26,609 Vandenberg and have a private launch 1109 00:49:35,390 --> 00:49:31,740 site in Texas so no we're not looking at 1110 00:49:36,890 --> 00:49:35,400 at Wallops at this point in time but 1111 00:49:38,960 --> 00:49:36,900 some go to the phone bridge for a 1112 00:49:43,700 --> 00:49:38,970 follow-up question from Michael Balfour 1113 00:49:45,170 --> 00:49:43,710 from Popular Mechanics Michael I think 1114 00:49:47,420 --> 00:49:45,180 I'm good my questions being answered 1115 00:49:49,700 --> 00:49:47,430 thank you okay you bet how about 1116 00:49:53,210 --> 00:49:49,710 checking back in with Jason Townsend on 1117 00:49:56,900 --> 00:49:53,220 where we are with questions coming in on 1118 00:49:58,730 --> 00:49:56,910 the hashtag ask NASA sure this question 1119 00:50:00,109 --> 00:49:58,740 comes from Twitter user BOE who asked I 1120 00:50:02,690 --> 00:50:00,119 would like to know if there are plans to 1121 00:50:06,829 --> 00:50:02,700 expand the ISS and or remove or replace 1122 00:50:10,190 --> 00:50:06,839 sections let's see our Russian 1123 00:50:13,880 --> 00:50:10,200 colleagues are considering an addition 1124 00:50:15,410 --> 00:50:13,890 of two or three modules that has not 1125 00:50:18,650 --> 00:50:15,420 been finalized but they have been 1126 00:50:21,950 --> 00:50:18,660 talking about adding a power module and 1127 00:50:23,690 --> 00:50:21,960 a laboratory module the Ameland in fact 1128 00:50:28,279 --> 00:50:23,700 was supposed to supply I was supposed to 1129 00:50:32,359 --> 00:50:28,289 fly this year 2015 but it's now pushed 1130 00:50:34,729 --> 00:50:32,369 into late 2017 or maybe later there are 1131 00:50:38,539 --> 00:50:34,739 other opportunities perhaps for four 1132 00:50:42,319 --> 00:50:38,549 modules to come to ISS the big loaf team 1133 00:50:44,029 --> 00:50:42,329 is building a small demonstration module 1134 00:50:46,339 --> 00:50:44,039 inflatable module that will fly to ISS 1135 00:50:50,420 --> 00:50:46,349 it's not meant to stay permanently on 1136 00:50:52,700 --> 00:50:50,430 board but it it is supposed to arrive as 1137 00:50:55,479 --> 00:50:52,710 well on SpaceX eight actually and spend 1138 00:50:59,539 --> 00:50:55,489 some time on the aft port of a node 3 1139 00:51:01,940 --> 00:50:59,549 and and there could be other expiration 1140 00:51:04,549 --> 00:51:01,950 type modules that might need to come to 1141 00:51:07,789 --> 00:51:04,559 ISS for a short period of time for 1142 00:51:09,950 --> 00:51:07,799 demonstration and checkout so the size 1143 00:51:10,250 --> 00:51:09,960 the station is set for the job that has 1144 00:51:12,230 --> 00:51:10,260 to 1145 00:51:15,980 --> 00:51:12,240 but it's possible that modules could 1146 00:51:18,770 --> 00:51:15,990 come based on supporting other other 1147 00:51:20,000 --> 00:51:18,780 research and technology efforts and of 1148 00:51:21,830 --> 00:51:20,010 course as I mentioned our Russian 1149 00:51:25,940 --> 00:51:21,840 colleagues are looking at some potential 1150 00:51:27,470 --> 00:51:25,950 additions as well okay wonderful this 1151 00:51:29,750 --> 00:51:27,480 other question here comes from Twitter 1152 00:51:35,320 --> 00:51:29,760 user Ricky who asks so what exactly are 1153 00:51:43,640 --> 00:51:35,330 you taking up there food fuel fuel no 1154 00:51:48,100 --> 00:51:43,650 food clothing supplies research and an 1155 00:51:50,930 --> 00:51:48,110 exterior experiment for measuring 1156 00:51:53,090 --> 00:51:50,940 aerosols in the atmosphere which is 1157 00:51:56,630 --> 00:51:53,100 actually helps on the study of global 1158 00:52:02,800 --> 00:51:56,640 warming so we continue that's kind of 1159 00:52:06,620 --> 00:52:02,810 the standard fare it's usually about 30% 1160 00:52:15,910 --> 00:52:06,630 cruise supplies and food 30% research 1161 00:52:19,130 --> 00:52:15,920 and the other 30% is spare parts James 1162 00:52:20,480 --> 00:52:19,140 thanks again James Dean flora today Mike 1163 00:52:23,750 --> 00:52:20,490 I was wondering if you could touch on a 1164 00:52:24,650 --> 00:52:23,760 plan to fly Cygnus on Atlas 5 and just 1165 00:52:25,970 --> 00:52:24,660 that being like a different 1166 00:52:27,620 --> 00:52:25,980 configuration that hasn't been 1167 00:52:31,400 --> 00:52:27,630 demonstrated like these other vehicles 1168 00:52:33,770 --> 00:52:31,410 were what were there any issues with 1169 00:52:36,500 --> 00:52:33,780 that or is it just like that you know 1170 00:52:39,320 --> 00:52:36,510 sort of proven rocket flying any other 1171 00:52:41,360 --> 00:52:39,330 payload and and also for either you or 1172 00:52:43,520 --> 00:52:41,370 Hans just wondering you know if SpaceX 1173 00:52:46,940 --> 00:52:43,530 found itself in the exact same position 1174 00:52:50,690 --> 00:52:46,950 would you also look to Atlas 5 to fly a 1175 00:52:52,040 --> 00:52:50,700 dragon so you'd have to get the details 1176 00:52:54,320 --> 00:52:52,050 from orbital but they have some 1177 00:52:56,870 --> 00:52:54,330 experience with the Atlas design and 1178 00:52:59,480 --> 00:52:56,880 flying their bus which is the Cygnus is 1179 00:53:03,620 --> 00:52:59,490 based on a bus that they use throughout 1180 00:53:07,850 --> 00:53:03,630 their satellite fleet and and so that 1181 00:53:10,370 --> 00:53:07,860 gives them great confidence that they 1182 00:53:12,890 --> 00:53:10,380 can fly this spacecraft onboard the 1183 00:53:13,970 --> 00:53:12,900 Atlas of course you have to adapt to it 1184 00:53:15,530 --> 00:53:13,980 and you have to do quite a bit of loads 1185 00:53:17,930 --> 00:53:15,540 analysis to convince yourself you're 1186 00:53:20,060 --> 00:53:17,940 okay so we will look at all that to make 1187 00:53:22,550 --> 00:53:20,070 sure that the environment won't damage 1188 00:53:24,590 --> 00:53:22,560 our hardware all the normal things we do 1189 00:53:27,320 --> 00:53:24,600 to clear a Cygnus 1190 00:53:30,140 --> 00:53:27,330 to approach ISS it's the same spacecraft 1191 00:53:31,640 --> 00:53:30,150 so that normal work will be done and 1192 00:53:34,550 --> 00:53:31,650 that's not different than what we've 1193 00:53:37,400 --> 00:53:34,560 done before the only other thing we'd 1194 00:53:39,890 --> 00:53:37,410 have to look at is the vehicle and how 1195 00:53:41,300 --> 00:53:39,900 the interfaces to the vehicle and 1196 00:53:43,100 --> 00:53:41,310 understand that performance of course 1197 00:53:45,770 --> 00:53:43,110 it's an atlas and there's quite a bit of 1198 00:53:49,760 --> 00:53:45,780 data on the Atlas vehicle itself so in 1199 00:53:50,870 --> 00:53:49,770 that respect it won't be a huge amount 1200 00:53:52,420 --> 00:53:50,880 of work probably the biggest thing that 1201 00:53:54,860 --> 00:53:52,430 has to happen is they have to do all the 1202 00:53:57,140 --> 00:53:54,870 environmental analysis to confirm that 1203 00:53:58,850 --> 00:53:57,150 Cygnus will be okay and to help us know 1204 00:54:00,790 --> 00:53:58,860 that the cargo inside will be fine 1205 00:54:02,720 --> 00:54:00,800 that's probably the biggest Delta for us 1206 00:54:06,680 --> 00:54:02,730 okay we're gonna try to see if we can 1207 00:54:09,260 --> 00:54:06,690 squeeze three more questions in I'm 1208 00:54:10,760 --> 00:54:09,270 Justin Beaupre with NASA social actually 1209 00:54:13,040 --> 00:54:10,770 I have a question regarding the weather 1210 00:54:15,500 --> 00:54:13,050 for the autonomous space board drone 1211 00:54:17,720 --> 00:54:15,510 ship I don't know if you're working 1212 00:54:19,370 --> 00:54:17,730 directly with them but what kind of 1213 00:54:22,010 --> 00:54:19,380 weather might we be seeing as well as 1214 00:54:24,350 --> 00:54:22,020 maybe what type of weather should we be 1215 00:54:24,980 --> 00:54:24,360 worried about maybe that's more towards 1216 00:54:27,020 --> 00:54:24,990 you Hans 1217 00:54:29,210 --> 00:54:27,030 for the restrictions that they might 1218 00:54:36,470 --> 00:54:29,220 have when coming because we're not 1219 00:54:39,500 --> 00:54:36,480 entirely sure what to expect wave height 1220 00:54:40,670 --> 00:54:39,510 forecast looking at wave heights for 1221 00:54:42,890 --> 00:54:40,680 tomorrow morning to be about five to 1222 00:54:44,720 --> 00:54:42,900 seven feet and then behind that front 1223 00:54:47,570 --> 00:54:44,730 and then they'll pick up if we happen to 1224 00:54:49,250 --> 00:54:47,580 slip into Friday then waves will pick up 1225 00:54:50,900 --> 00:54:49,260 on Thursday will be a max of about 1226 00:54:52,880 --> 00:54:50,910 twelve to sixteen feet and then they'll 1227 00:54:56,030 --> 00:54:52,890 back down for a Friday morning to about 1228 00:54:58,280 --> 00:54:56,040 six to eight feet so Hans explained what 1229 00:55:00,530 --> 00:54:58,290 the thresholds are for that so assistant 1230 00:55:03,220 --> 00:55:00,540 you know the the drone ship is pretty 1231 00:55:06,410 --> 00:55:03,230 big and doesn't those those wave heights 1232 00:55:09,230 --> 00:55:06,420 don't have any significant impact on the 1233 00:55:10,580 --> 00:55:09,240 landing and in terms of clouds I don't 1234 00:55:13,250 --> 00:55:10,590 think we have the same imitations that 1235 00:55:14,660 --> 00:55:13,260 we have on the way on the ascent I don't 1236 00:55:17,150 --> 00:55:14,670 think there's a stick cloud rule on the 1237 00:55:23,740 --> 00:55:17,160 way coming down so there's a lot less 1238 00:55:26,630 --> 00:55:23,750 limitations honestly in terms of landing 1239 00:55:28,970 --> 00:55:26,640 okay here on the front row my name is 1240 00:55:31,370 --> 00:55:28,980 Adam Byerly with NASA social and NASA 1241 00:55:32,960 --> 00:55:31,380 pics org I was wondering if you could 1242 00:55:35,330 --> 00:55:32,970 tell us a little bit more about the 1243 00:55:37,310 --> 00:55:35,340 actual process of capturing the dragon 1244 00:55:38,270 --> 00:55:37,320 spaceship to the International Space 1245 00:55:41,120 --> 00:55:38,280 Station 1246 00:55:43,760 --> 00:55:41,130 how long that takes the actual procedure 1247 00:55:49,280 --> 00:55:43,770 and how it may different differ from 1248 00:55:55,250 --> 00:55:49,290 other missions like this mean to you 1249 00:55:58,160 --> 00:55:55,260 okay well I guess it's an arbor I think 1250 00:55:59,870 --> 00:55:58,170 the Army's radio approach in the sense 1251 00:56:03,830 --> 00:55:59,880 that dragon basically creeps up on 1252 00:56:07,010 --> 00:56:03,840 another station over a period of I think 1253 00:56:10,850 --> 00:56:07,020 it's like maybe six seven hours there's 1254 00:56:12,230 --> 00:56:10,860 certain whole ports in there I want to 1255 00:56:16,130 --> 00:56:12,240 say something at the order of you know 1256 00:56:18,170 --> 00:56:16,140 several kilometers out once you enter 1257 00:56:19,520 --> 00:56:18,180 the the key parts here there's going to 1258 00:56:22,100 --> 00:56:19,530 be more whole points at two and a half 1259 00:56:23,810 --> 00:56:22,110 and so on so forth every whole point you 1260 00:56:26,570 --> 00:56:23,820 verify that you're good to go you have 1261 00:56:27,950 --> 00:56:26,580 all your redundancy still working you 1262 00:56:31,100 --> 00:56:27,960 got enough per pound and so on and so 1263 00:56:34,160 --> 00:56:31,110 forth it's very very elaborate and 1264 00:56:36,350 --> 00:56:34,170 cautious approach I would say the arbor 1265 00:56:39,950 --> 00:56:36,360 has also certain advantages that if you 1266 00:56:42,320 --> 00:56:39,960 lose total control at one time you did 1267 00:56:46,340 --> 00:56:42,330 not eat not endangering the the ISS at 1268 00:56:48,290 --> 00:56:46,350 all it's a very safe approach it's it's 1269 00:56:50,090 --> 00:56:48,300 not not like tailgating basically yeah 1270 00:56:53,750 --> 00:56:50,100 you would you drop off if you lose 1271 00:56:55,220 --> 00:56:53,760 control so um as you work your way up on 1272 00:56:58,000 --> 00:56:55,230 the arbor which takes a couple hours you 1273 00:57:00,470 --> 00:56:58,010 then stop at 10 meters basically and 1274 00:57:04,670 --> 00:57:00,480 once we got the go for capture which is 1275 00:57:07,220 --> 00:57:04,680 always a traumatic moment I forgot 1276 00:57:09,050 --> 00:57:07,230 actually the time it's for its roughly 1277 00:57:11,210 --> 00:57:09,060 44 hours after launch so it's going in 1278 00:57:14,650 --> 00:57:11,220 the middle of the night instead of early 1279 00:57:17,690 --> 00:57:14,660 morning but once we get that command 1280 00:57:18,410 --> 00:57:17,700 dragon basically decides not to do 1281 00:57:20,660 --> 00:57:18,420 anything anymore 1282 00:57:22,780 --> 00:57:20,670 it isolates itself it shuts down 1283 00:57:26,230 --> 00:57:22,790 propellant so that there is no 1284 00:57:30,410 --> 00:57:26,240 Northwester firing when the station arm 1285 00:57:33,050 --> 00:57:30,420 grapples it and so he flies they're 1286 00:57:35,990 --> 00:57:33,060 gonna apply to a box right about 10 1287 00:57:37,910 --> 00:57:36,000 meters away from station and and as long 1288 00:57:40,700 --> 00:57:37,920 as they're in the in the box right then 1289 00:57:44,240 --> 00:57:40,710 then as Han says that at some point they 1290 00:57:46,730 --> 00:57:44,250 go to free drift the crew lose the the 1291 00:57:50,390 --> 00:57:46,740 latching end effector into grabs the 1292 00:57:52,280 --> 00:57:50,400 a vehicle and then and then rigid Isis 1293 00:57:54,890 --> 00:57:52,290 then at that point actually the ground 1294 00:57:56,570 --> 00:57:54,900 commands the arm the crew goes off and 1295 00:57:58,580 --> 00:57:56,580 does other things to grab the ground 1296 00:58:00,920 --> 00:57:58,590 commands the arm to put the dragon over 1297 00:58:02,600 --> 00:58:00,930 to the common berthing mechanism at that 1298 00:58:04,990 --> 00:58:02,610 point the crew comes back they operate 1299 00:58:16,060 --> 00:58:05,000 the CBM in conjunction with the ground 1300 00:58:19,040 --> 00:58:16,070 and attached to the station 0g News 1301 00:58:25,730 --> 00:58:19,050 which is basically about the range 1302 00:58:27,800 --> 00:58:25,740 around the autonomous spaceport drone in 1303 00:58:30,170 --> 00:58:27,810 respect of anything coming into it which 1304 00:58:32,870 --> 00:58:30,180 is like a ship that shouldn't be there 1305 00:58:35,080 --> 00:58:32,880 kind of thing what's the issue in 1306 00:58:38,090 --> 00:58:35,090 respect of all that just abort the 1307 00:58:41,870 --> 00:58:38,100 attempt and in respect of Mike I was 1308 00:58:43,640 --> 00:58:41,880 just wondering about any items within 1309 00:58:45,109 --> 00:58:43,650 the Dragon which is related to the 1310 00:58:46,960 --> 00:58:45,119 one-year mission that's coming up 1311 00:58:55,000 --> 00:58:46,970 whether you're starting to stage 1312 00:58:58,280 --> 00:58:56,300 okay 1313 00:59:02,800 --> 00:58:58,290 so any ship going in between or getting 1314 00:59:09,190 --> 00:59:05,570 it's obviously it's a safety safety 1315 00:59:12,440 --> 00:59:09,200 issue as this human life over over over 1316 00:59:16,250 --> 00:59:12,450 something else so you would chase it 1317 00:59:19,760 --> 00:59:16,260 away and yes dragon has some of supplies 1318 00:59:21,410 --> 00:59:19,770 for the one-year mission I think some of 1319 00:59:23,420 --> 00:59:21,420 its already up there and then some of it 1320 00:59:24,890 --> 00:59:23,430 comes up on on the dragon some of it 1321 00:59:28,099 --> 00:59:24,900 actually comes up on the vehicle if they 1322 00:59:30,200 --> 00:59:28,109 fly on as well so some so so a portion 1323 00:59:32,930 --> 00:59:30,210 of their their supplies go up on space 1324 00:59:37,410 --> 00:59:34,980 okay I'm sorry that we didn't get to 1325 00:59:39,870 --> 00:59:37,420 everyone's question but we have to wrap 1326 00:59:42,030 --> 00:59:39,880 it up and get ready for launch tomorrow 1327 00:59:44,970 --> 00:59:42,040 morning the exact liftoff time that we 1328 00:59:46,950 --> 00:59:44,980 have now is 6:20 and 29 seconds a.m. 1329 00:59:48,780 --> 00:59:46,960 Eastern Standard Time our NASA 1330 00:59:51,150 --> 00:59:48,790 television coverage will begin at 5:00 1331 00:59:53,010 --> 00:59:51,160 a.m. and between now and then you can
