1 00:00:04,870 --> 00:00:03,270 right our third speaker is eric conway 2 00:00:07,190 --> 00:00:04,880 who's a historian at the jet propulsion 3 00:00:08,790 --> 00:00:07,200 laboratory eric is the author of several 4 00:00:10,709 --> 00:00:08,800 books in the history of space technology 5 00:00:12,230 --> 00:00:10,719 and aeronautical engineering 6 00:00:14,629 --> 00:00:12,240 including the techno-politics of 7 00:00:16,550 --> 00:00:14,639 supersonic transportation atmospheric 8 00:00:19,029 --> 00:00:16,560 science at nasa and a book on blind 9 00:00:21,109 --> 00:00:19,039 landings among other last year eric won 10 00:00:22,550 --> 00:00:21,119 the davis prize from the society for the 11 00:00:24,550 --> 00:00:22,560 history of science 12 00:00:26,150 --> 00:00:24,560 for extraordinary writing for the public 13 00:00:27,349 --> 00:00:26,160 domain but i should also note that his 14 00:00:28,870 --> 00:00:27,359 work in the history of science and 15 00:00:30,230 --> 00:00:28,880 technology and in the history of space 16 00:00:32,069 --> 00:00:30,240 exploration has been both foundational 17 00:00:33,990 --> 00:00:32,079 and extremely influential 18 00:00:35,750 --> 00:00:34,000 so eric is currently working on a 19 00:00:37,830 --> 00:00:35,760 history of mars exploration since the 20 00:00:42,549 --> 00:00:37,840 1970s and he'll be speaking to us today 21 00:00:45,990 --> 00:00:43,990 first i have to thank the previous 22 00:00:48,470 --> 00:00:46,000 speakers today you've made my problem of 23 00:00:49,910 --> 00:00:48,480 getting through this talk on time much 24 00:00:51,910 --> 00:00:49,920 easier because i don't have to cover 25 00:00:53,670 --> 00:00:51,920 some programmatic stuff that's essential 26 00:00:57,029 --> 00:00:53,680 to the story i actually want to tell 27 00:00:59,189 --> 00:00:57,039 which is about really engineering for 28 00:01:01,110 --> 00:00:59,199 mars sample return 29 00:01:03,029 --> 00:01:01,120 now you've also heard this mentioned 30 00:01:05,750 --> 00:01:03,039 many times this is the mars science 31 00:01:07,590 --> 00:01:05,760 laboratory curiosity landing what story 32 00:01:09,990 --> 00:01:07,600 you probably don't know is that this 33 00:01:13,190 --> 00:01:10,000 architecture was the loser of a sample 34 00:01:15,429 --> 00:01:13,200 return study done in 2000 around jpl and 35 00:01:18,230 --> 00:01:15,439 then won again a few years later and 36 00:01:20,070 --> 00:01:18,240 that's the story i want to tell 37 00:01:21,429 --> 00:01:20,080 there are samples of mars on earth most 38 00:01:23,350 --> 00:01:21,439 audiences i give this talk to don't 39 00:01:24,789 --> 00:01:23,360 realize that we have these meteorites 40 00:01:27,270 --> 00:01:24,799 that were collected from antarctica this 41 00:01:28,870 --> 00:01:27,280 is the famous one from 1996 that was 42 00:01:30,789 --> 00:01:28,880 supposed to have been found to have 43 00:01:32,870 --> 00:01:30,799 signatures of life on it the reason i 44 00:01:34,630 --> 00:01:32,880 bring it up is to get across the idea 45 00:01:36,789 --> 00:01:34,640 that what scientists want is not just 46 00:01:39,429 --> 00:01:36,799 any old sample of mars what they want is 47 00:01:40,469 --> 00:01:39,439 to pick them and that's important 48 00:01:41,830 --> 00:01:40,479 because 49 00:01:43,590 --> 00:01:41,840 you heard from rich zurich how 50 00:01:45,590 --> 00:01:43,600 frustrating the viking missions were to 51 00:01:47,270 --> 00:01:45,600 some scientists because they could see 52 00:01:49,590 --> 00:01:47,280 some wonderful rocks that they wanted to 53 00:01:51,990 --> 00:01:49,600 reach out and grab and test and couldn't 54 00:01:54,230 --> 00:01:52,000 they couldn't get to them so when this 55 00:01:56,069 --> 00:01:54,240 strategy for exploration of the inner 56 00:01:58,950 --> 00:01:56,079 planets is published by the complex 57 00:02:01,109 --> 00:01:58,960 committee in 1978 it's 58 00:02:04,149 --> 00:02:01,119 contains a discussion of mars sample 59 00:02:06,069 --> 00:02:04,159 return that favors doing it with some 60 00:02:07,910 --> 00:02:06,079 sort of rover either a short range rover 61 00:02:09,109 --> 00:02:07,920 that could go maybe only a few meters 62 00:02:10,630 --> 00:02:09,119 but what they make clear is what they 63 00:02:13,430 --> 00:02:10,640 really wanted was a long range one that 64 00:02:14,949 --> 00:02:13,440 might cover hundreds of kilometers 65 00:02:16,630 --> 00:02:14,959 now the threads of my story are design 66 00:02:18,229 --> 00:02:16,640 and engineering in support of science 67 00:02:20,470 --> 00:02:18,239 there's a second thread of competition 68 00:02:22,070 --> 00:02:20,480 for funds i'll get to at the end and 69 00:02:23,510 --> 00:02:22,080 ultimately i want to leave you with the 70 00:02:25,750 --> 00:02:23,520 thought that you've already heard today 71 00:02:27,830 --> 00:02:25,760 that nasa has this dual self-image 72 00:02:30,630 --> 00:02:27,840 sometimes i call it schizophrenia as a 73 00:02:32,869 --> 00:02:30,640 scientific agency and also the agency 74 00:02:35,110 --> 00:02:32,879 that's an agent of human expansion into 75 00:02:36,869 --> 00:02:35,120 the solar system 76 00:02:38,949 --> 00:02:36,879 now that complex study led to a set of 77 00:02:41,030 --> 00:02:38,959 studies at jpl that i'm not going to 78 00:02:43,030 --> 00:02:41,040 talk about i had there are actually four 79 00:02:44,550 --> 00:02:43,040 separate sets of sample return studies 80 00:02:46,390 --> 00:02:44,560 major ones anyways that i talk about in 81 00:02:47,589 --> 00:02:46,400 the full length of this paper i can't do 82 00:02:49,830 --> 00:02:47,599 them all in 20 minutes so i'm going to 83 00:02:51,990 --> 00:02:49,840 do two i'm going to skip merrily over 84 00:02:53,509 --> 00:02:52,000 this period of time and get on to the 85 00:02:55,350 --> 00:02:53,519 second act 86 00:02:58,630 --> 00:02:55,360 of the simple return in the faster 87 00:03:00,070 --> 00:02:58,640 better cheaper era during the 1990s 88 00:03:01,910 --> 00:03:00,080 one of the other speakers already 89 00:03:04,710 --> 00:03:01,920 introduced one of my favorite poster 90 00:03:06,309 --> 00:03:04,720 boys the mars observer mission um this 91 00:03:07,910 --> 00:03:06,319 has become legendary in the planetary 92 00:03:09,830 --> 00:03:07,920 science community for being over cost 93 00:03:11,350 --> 00:03:09,840 and then not returning anything uh one 94 00:03:13,509 --> 00:03:11,360 corrective to a previous speaker is that 95 00:03:15,350 --> 00:03:13,519 the primary overrun came from the launch 96 00:03:16,869 --> 00:03:15,360 delay of 26 months not from the 97 00:03:19,030 --> 00:03:16,879 instruments they were the second largest 98 00:03:21,190 --> 00:03:19,040 piece of the overrun either way we got 99 00:03:22,869 --> 00:03:21,200 nothing essentially out of this except 100 00:03:24,550 --> 00:03:22,879 the value of the systems engineering 101 00:03:27,509 --> 00:03:24,560 which contributed to a number of 102 00:03:29,990 --> 00:03:27,519 missions later on um once dan golden and 103 00:03:32,149 --> 00:03:30,000 west huntress have reformulated the idea 104 00:03:35,670 --> 00:03:32,159 of a faster better cheaper and then b 105 00:03:37,350 --> 00:03:35,680 the idea of a mars program 106 00:03:40,149 --> 00:03:37,360 um this is the mars program that came 107 00:03:41,350 --> 00:03:40,159 out of their work in the early 1990s and 108 00:03:43,910 --> 00:03:41,360 i show this 109 00:03:46,630 --> 00:03:43,920 because sample return over here oh this 110 00:03:48,869 --> 00:03:46,640 is very weak unfortunately appears 111 00:03:50,630 --> 00:03:48,879 the idea of the surveyor program it was 112 00:03:52,949 --> 00:03:50,640 called is there would be an orbiter and 113 00:03:55,509 --> 00:03:52,959 land two missions sent every 26 months 114 00:03:57,589 --> 00:03:55,519 every launch period to mars the first 115 00:03:59,350 --> 00:03:57,599 pair would be an orbiter and a lander 116 00:04:03,350 --> 00:03:59,360 the second pair again an orbiter and a 117 00:04:04,710 --> 00:04:03,360 lander going in 2001 and then in 2003 118 00:04:06,949 --> 00:04:04,720 you would get the beginning of the 119 00:04:08,949 --> 00:04:06,959 sample return campaign 120 00:04:10,949 --> 00:04:08,959 this was challenging technologically 121 00:04:13,110 --> 00:04:10,959 because the missions were supposed to be 122 00:04:14,949 --> 00:04:13,120 implemented by contract they were also 123 00:04:17,030 --> 00:04:14,959 supposed to be competed except for 124 00:04:19,430 --> 00:04:17,040 sample return which meant they didn't 125 00:04:21,110 --> 00:04:19,440 lead up to a technologically coherent 126 00:04:23,110 --> 00:04:21,120 mission set in other words they didn't 127 00:04:24,710 --> 00:04:23,120 build towards sample return from the 128 00:04:28,870 --> 00:04:24,720 standpoint of the engineers that had to 129 00:04:31,830 --> 00:04:30,150 there we go 130 00:04:33,189 --> 00:04:31,840 at the same time outside the mars 131 00:04:34,550 --> 00:04:33,199 program this of course is mars 132 00:04:36,390 --> 00:04:34,560 pathfinder which was done under the 133 00:04:37,990 --> 00:04:36,400 discovery program 134 00:04:40,710 --> 00:04:38,000 was set up to 135 00:04:41,990 --> 00:04:40,720 demonstrate low-cost mars landings uh 136 00:04:44,310 --> 00:04:42,000 this is a famous picture of the 137 00:04:46,550 --> 00:04:44,320 sojourner rover starting to deliver the 138 00:04:48,790 --> 00:04:46,560 technical promise of of the ability to 139 00:04:50,790 --> 00:04:48,800 reach out and get samples from distant 140 00:04:52,790 --> 00:04:50,800 areas the mars pathfinder mission of 141 00:04:55,189 --> 00:04:52,800 course was enormously popular with the 142 00:04:57,670 --> 00:04:55,199 general public so it validated the idea 143 00:04:59,909 --> 00:04:57,680 of having a mars program 144 00:05:02,230 --> 00:04:59,919 it also validated the idea faster better 145 00:05:04,790 --> 00:05:02,240 cheaper the lander cost about 150 146 00:05:06,790 --> 00:05:04,800 million dollars the project overall 310 147 00:05:11,590 --> 00:05:06,800 million dollars which is about one tenth 148 00:05:13,029 --> 00:05:11,600 of what the nation spent on viking 149 00:05:15,189 --> 00:05:13,039 it was supposed to be followed by this 150 00:05:17,350 --> 00:05:15,199 mission the mars polar lander 151 00:05:18,550 --> 00:05:17,360 jpl selected as its contract partner 152 00:05:20,230 --> 00:05:18,560 lockheed 153 00:05:23,110 --> 00:05:20,240 the polar lander was to be of their 154 00:05:25,110 --> 00:05:23,120 design this was a pulsed jet lander not 155 00:05:27,430 --> 00:05:25,120 a throttle liquid the way viking had 156 00:05:30,870 --> 00:05:27,440 been done the idea was to land near the 157 00:05:31,909 --> 00:05:30,880 martian north pole take samples and test 158 00:05:34,390 --> 00:05:31,919 of 159 00:05:37,189 --> 00:05:34,400 more polar but not necessarily on ice 160 00:05:39,430 --> 00:05:37,199 samples this mission was implemented the 161 00:05:41,430 --> 00:05:39,440 contract value for this project was 120 162 00:05:44,310 --> 00:05:41,440 million dollars the project budget 163 00:05:45,990 --> 00:05:44,320 overall was a bit over 250 million so 164 00:05:47,510 --> 00:05:46,000 nasa was asking jpl to deliver two 165 00:05:49,990 --> 00:05:47,520 spacecraft for 166 00:05:52,790 --> 00:05:50,000 less than it spent on one in mars 167 00:05:54,390 --> 00:05:52,800 pathfinder 168 00:05:56,309 --> 00:05:54,400 and the sample return architecture was 169 00:05:57,990 --> 00:05:56,319 then based to be based on the lockheed 170 00:05:59,830 --> 00:05:58,000 lander 171 00:06:02,469 --> 00:05:59,840 the sample return architecture was it 172 00:06:04,710 --> 00:06:02,479 was a three-way effort of jpl 173 00:06:07,430 --> 00:06:04,720 lockheed in denver really and the french 174 00:06:10,230 --> 00:06:07,440 space agency canes was to start off in 175 00:06:11,909 --> 00:06:10,240 2003 with either a delta or atlas launch 176 00:06:12,950 --> 00:06:11,919 putting up the lockheed lander with a 177 00:06:14,550 --> 00:06:12,960 small 178 00:06:16,870 --> 00:06:14,560 sojourner derived but larger than 179 00:06:19,189 --> 00:06:16,880 sojourn or more of an athena sized rover 180 00:06:21,270 --> 00:06:19,199 of around 120 kilograms that would go 181 00:06:22,870 --> 00:06:21,280 out and collect samples and then shoot 182 00:06:24,150 --> 00:06:22,880 them off into space you can barely see 183 00:06:27,749 --> 00:06:24,160 it you'll see this better on the next 184 00:06:30,629 --> 00:06:27,759 diagram and into low mars orbit in 2005 185 00:06:32,710 --> 00:06:30,639 an arianny 5 with two more spacecraft 186 00:06:35,590 --> 00:06:32,720 another lander and a french-built 187 00:06:37,670 --> 00:06:35,600 orbiter would be sent to mars as well 188 00:06:40,390 --> 00:06:37,680 collect samples shoot them into orbit 189 00:06:42,950 --> 00:06:40,400 and then the orbiter would collect them 190 00:06:46,550 --> 00:06:42,960 and send them back to earth via an earth 191 00:06:51,350 --> 00:06:48,870 this is the scaled up lockheed sample 192 00:06:52,870 --> 00:06:51,360 return lander i pulled this out of a 193 00:06:54,550 --> 00:06:52,880 presentation by ed euler who is the 194 00:06:55,990 --> 00:06:54,560 lockheed program manager for it 195 00:06:56,950 --> 00:06:56,000 presented at one of the a double a 196 00:06:58,710 --> 00:06:56,960 meetings 197 00:07:00,710 --> 00:06:58,720 back in 2000 198 00:07:02,469 --> 00:07:00,720 excuse me in 99 this is the landing 199 00:07:04,070 --> 00:07:02,479 configuration you can see the mars 200 00:07:07,110 --> 00:07:04,080 ascent vehicle that's to shoot it into 201 00:07:10,230 --> 00:07:07,120 orbit here the rover and the platform is 202 00:07:11,430 --> 00:07:10,240 supposed to come down uh drill envelope 203 00:07:13,270 --> 00:07:11,440 for 204 00:07:14,710 --> 00:07:13,280 in case the rover didn't work or failed 205 00:07:16,150 --> 00:07:14,720 before coming back to the lander it had 206 00:07:19,110 --> 00:07:16,160 the ability to just grab a sample from 207 00:07:22,950 --> 00:07:19,120 where it landed and send that back 208 00:07:25,029 --> 00:07:22,960 as a technical problem this lander was 209 00:07:27,270 --> 00:07:25,039 substantial because it had to be scaled 210 00:07:29,189 --> 00:07:27,280 up considerably the polar lander was 211 00:07:30,870 --> 00:07:29,199 supposed to have a mass of about 290 212 00:07:32,950 --> 00:07:30,880 kilograms this thing had to be a bit 213 00:07:35,270 --> 00:07:32,960 about bit over a thousand 214 00:07:37,270 --> 00:07:35,280 anytime you scale up a piece of hardware 215 00:07:40,150 --> 00:07:37,280 to that degree you have to do a lot of 216 00:07:42,070 --> 00:07:40,160 redesign work and it as this project is 217 00:07:44,710 --> 00:07:42,080 set up at jpl the engineers begin to 218 00:07:46,950 --> 00:07:44,720 realize that they have they have 219 00:07:48,790 --> 00:07:46,960 technical issues with these legs because 220 00:07:51,589 --> 00:07:48,800 they're a bit fragile because the launch 221 00:07:53,749 --> 00:07:51,599 vehicle shrouds would not allow a long 222 00:07:55,510 --> 00:07:53,759 enough leg to give any substantial 223 00:07:56,629 --> 00:07:55,520 ground clearance so then you have the 224 00:07:58,230 --> 00:07:56,639 problem with well they're going to flex 225 00:08:00,230 --> 00:07:58,240 during impact when it hits the surface 226 00:08:01,670 --> 00:08:00,240 how much space can we have for that 227 00:08:03,350 --> 00:08:01,680 they ran into troubles with the load 228 00:08:05,510 --> 00:08:03,360 pass that would carry this down to the 229 00:08:08,150 --> 00:08:05,520 launch vehicle and so on and they began 230 00:08:10,790 --> 00:08:08,160 to question whether this design was 231 00:08:11,990 --> 00:08:10,800 actually sound they also began to 232 00:08:14,070 --> 00:08:12,000 question whether they're really going to 233 00:08:15,909 --> 00:08:14,080 have enough money under the 200 million 234 00:08:18,469 --> 00:08:15,919 a year budget that that this the 235 00:08:20,230 --> 00:08:18,479 surveyor project could give them 236 00:08:22,309 --> 00:08:20,240 but it's not in the end the money that 237 00:08:24,390 --> 00:08:22,319 gets them into deep trouble it's the 238 00:08:26,629 --> 00:08:24,400 loss of the polar lander 239 00:08:28,469 --> 00:08:26,639 when the polar lander is lost it's lost 240 00:08:29,350 --> 00:08:28,479 without any returning any telemetry at 241 00:08:32,310 --> 00:08:29,360 all 242 00:08:34,230 --> 00:08:32,320 so there is a study that of its failure 243 00:08:36,070 --> 00:08:34,240 they came to a set of conclusions that 244 00:08:37,829 --> 00:08:36,080 it was probably a touchdown flag that 245 00:08:39,589 --> 00:08:37,839 was miss set um 246 00:08:41,750 --> 00:08:39,599 jpl that's almost you know i think 247 00:08:43,350 --> 00:08:41,760 universally understood to be unlikely it 248 00:08:45,110 --> 00:08:43,360 failed for other reasons that were found 249 00:08:46,630 --> 00:08:45,120 by a project later on called mars 250 00:08:49,350 --> 00:08:46,640 phoenix when they took the o1 lander 251 00:08:50,710 --> 00:08:49,360 hardware to rework but at the time no 252 00:08:51,990 --> 00:08:50,720 one knew that 253 00:08:55,269 --> 00:08:52,000 all they knew is that the lockheed 254 00:08:57,509 --> 00:08:55,279 lander had failed and i didn't know why 255 00:08:59,509 --> 00:08:57,519 and that ended this sample return effort 256 00:09:02,870 --> 00:08:59,519 because it was based fundamentally on 257 00:09:03,990 --> 00:09:02,880 the success of the polar lander 258 00:09:06,710 --> 00:09:04,000 act three 259 00:09:09,030 --> 00:09:06,720 so i've now said that around jpl the 260 00:09:10,790 --> 00:09:09,040 sample return idea the architecture was 261 00:09:12,949 --> 00:09:10,800 already in trouble and the laboratory 262 00:09:14,550 --> 00:09:12,959 sets up a couple of design teams to 263 00:09:16,790 --> 00:09:14,560 revisit this 264 00:09:19,030 --> 00:09:16,800 as the sample return project itself is 265 00:09:20,710 --> 00:09:19,040 being shut down 266 00:09:22,389 --> 00:09:20,720 it starts out in the leadership of brian 267 00:09:24,230 --> 00:09:22,399 muirhead who had been the pathfinder 268 00:09:27,509 --> 00:09:24,240 project manager and had a number of the 269 00:09:29,269 --> 00:09:27,519 pathfinder veterans on these teams the 270 00:09:31,910 --> 00:09:29,279 idea of the bubble team study initially 271 00:09:33,670 --> 00:09:31,920 was to review each element of the 272 00:09:35,829 --> 00:09:33,680 architecture individually 273 00:09:37,990 --> 00:09:35,839 your head's team reviewed the lander 274 00:09:39,430 --> 00:09:38,000 they then morphed into a different set 275 00:09:41,590 --> 00:09:39,440 of studies but essentially the same 276 00:09:43,829 --> 00:09:41,600 people under another program manager by 277 00:09:45,350 --> 00:09:43,839 the name of jim graf known as a large 278 00:09:46,389 --> 00:09:45,360 lander study 279 00:09:48,310 --> 00:09:46,399 and this is where they begin to 280 00:09:50,550 --> 00:09:48,320 reformulate a different architecture for 281 00:09:52,790 --> 00:09:50,560 sample return this is the way the 282 00:09:54,550 --> 00:09:52,800 engineers like to tell their story this 283 00:09:56,630 --> 00:09:54,560 this is the polar lander the polar 284 00:09:59,590 --> 00:09:56,640 lander has a series of review boards 285 00:10:01,670 --> 00:09:59,600 that try to examine its failure 286 00:10:03,269 --> 00:10:01,680 this idea of robust rover egress here at 287 00:10:04,550 --> 00:10:03,279 the bottom for sample return was never 288 00:10:06,550 --> 00:10:04,560 addressed because they'd begun thinking 289 00:10:08,150 --> 00:10:06,560 about this egress problem and that leads 290 00:10:09,430 --> 00:10:08,160 them into this next phase which will 291 00:10:11,030 --> 00:10:09,440 eventually be called the mars 292 00:10:12,310 --> 00:10:11,040 smartlander 293 00:10:14,150 --> 00:10:12,320 now 294 00:10:15,590 --> 00:10:14,160 in this side this bubblehead team they 295 00:10:17,670 --> 00:10:15,600 come up with a variety of different 296 00:10:19,269 --> 00:10:17,680 potential architectures and this slide 297 00:10:21,190 --> 00:10:19,279 then one of the engineers built and i 298 00:10:23,509 --> 00:10:21,200 grabbed out of the presentation shows 299 00:10:26,150 --> 00:10:23,519 their of the evolution of their thinking 300 00:10:28,389 --> 00:10:26,160 from this tripod lander to what becomes 301 00:10:30,550 --> 00:10:28,399 the baseline or one of the baselines 302 00:10:32,790 --> 00:10:30,560 from this study and that is the idea of 303 00:10:34,710 --> 00:10:32,800 a pallet lander the pallet lander is an 304 00:10:36,790 --> 00:10:34,720 idea from the 1960s the idea is a 305 00:10:38,389 --> 00:10:36,800 crushable substructure five ten minutes 306 00:10:40,150 --> 00:10:38,399 okay thanks janet i'm doing pretty good 307 00:10:42,710 --> 00:10:40,160 then the idea is you have a crushable 308 00:10:44,630 --> 00:10:42,720 substructure that 309 00:10:45,990 --> 00:10:44,640 allows means you don't have a very large 310 00:10:47,509 --> 00:10:46,000 ground clearance once the thing is 311 00:10:49,190 --> 00:10:47,519 sitting on the ground and that's 312 00:10:51,509 --> 00:10:49,200 desirable from the standpoint of getting 313 00:10:53,670 --> 00:10:51,519 a big rover off the deck if you have it 314 00:10:56,069 --> 00:10:53,680 sitting very high standing which you on 315 00:10:57,990 --> 00:10:56,079 a leg lander you want for rock avoidance 316 00:11:00,069 --> 00:10:58,000 as the rover moves across the surface of 317 00:11:01,670 --> 00:11:00,079 the thing the whole spacecraft will try 318 00:11:03,269 --> 00:11:01,680 to tip and if you are unfortunate and 319 00:11:04,870 --> 00:11:03,279 either landed on a slope or on a big 320 00:11:07,190 --> 00:11:04,880 rock you can flip the whole darn thing 321 00:11:09,269 --> 00:11:07,200 over this pallet lander is a little more 322 00:11:10,710 --> 00:11:09,279 immune to this its drawback is that your 323 00:11:12,630 --> 00:11:10,720 the fuel tanks are down here on the 324 00:11:14,870 --> 00:11:12,640 bottom and the structure has to protect 325 00:11:17,269 --> 00:11:14,880 those because the fuel we use hydrazine 326 00:11:19,990 --> 00:11:17,279 is both toxic and corrosive and we don't 327 00:11:20,870 --> 00:11:20,000 want it all over the guts of the lander 328 00:11:21,670 --> 00:11:20,880 so 329 00:11:24,150 --> 00:11:21,680 that's 330 00:11:26,310 --> 00:11:24,160 one idea they come up with 331 00:11:27,590 --> 00:11:26,320 second idea airbag system we've already 332 00:11:29,110 --> 00:11:27,600 seen the use of airbags on mars 333 00:11:30,389 --> 00:11:29,120 pathfinder why not continue with that 334 00:11:31,910 --> 00:11:30,399 success 335 00:11:33,110 --> 00:11:31,920 except in this case because it's a much 336 00:11:35,269 --> 00:11:33,120 larger lander again you're trying to 337 00:11:36,710 --> 00:11:35,279 land a thousand kilograms they needed 338 00:11:38,790 --> 00:11:36,720 more they decided they needed more 339 00:11:41,509 --> 00:11:38,800 controllability and here's the idea is 340 00:11:43,750 --> 00:11:41,519 to use a throttleable liquid 341 00:11:45,910 --> 00:11:43,760 descent stage to 342 00:11:47,750 --> 00:11:45,920 to lower the lander down more gently 343 00:11:49,829 --> 00:11:47,760 than pathfinder had but they still 344 00:11:51,670 --> 00:11:49,839 thought they needed these airbags to 345 00:11:54,389 --> 00:11:51,680 protect it at the final at the as 346 00:11:56,470 --> 00:11:54,399 towards terminal descent um at the end 347 00:11:58,150 --> 00:11:56,480 again you see the the descent stage will 348 00:11:59,430 --> 00:11:58,160 fly away at the end and crash the 349 00:12:00,949 --> 00:11:59,440 advantage of that is you don't have to 350 00:12:02,470 --> 00:12:00,959 protect the fuel tanks because you don't 351 00:12:04,310 --> 00:12:02,480 care what happens the descent stage 352 00:12:05,990 --> 00:12:04,320 after it hits the ground um there are a 353 00:12:08,629 --> 00:12:06,000 number of advantages and disadvantages 354 00:12:11,829 --> 00:12:08,639 the airbags provided writing ability a 355 00:12:13,910 --> 00:12:11,839 disadvantage um that they didn't quite 356 00:12:14,790 --> 00:12:13,920 realize very thoroughly yet 357 00:12:15,590 --> 00:12:14,800 because 358 00:12:17,829 --> 00:12:15,600 well 359 00:12:19,670 --> 00:12:17,839 is how to get heat out of the spacecraft 360 00:12:21,670 --> 00:12:19,680 in cruise these airbags are insulators 361 00:12:23,430 --> 00:12:21,680 the aeroshell will be an insulator and 362 00:12:26,790 --> 00:12:23,440 if this is a particularly big problem if 363 00:12:28,470 --> 00:12:26,800 nasa decides to use an rtg power source 364 00:12:30,389 --> 00:12:28,480 because there's much more heat to be 365 00:12:34,069 --> 00:12:30,399 dissipated through all these layers of 366 00:12:36,069 --> 00:12:34,079 insulation while it's in flight to mars 367 00:12:37,509 --> 00:12:36,079 so advantages descent stage never has to 368 00:12:38,710 --> 00:12:37,519 be shut off the propulsion hardware 369 00:12:41,110 --> 00:12:38,720 doesn't have to be protected better 370 00:12:44,150 --> 00:12:41,120 velocity control disadvantages interface 371 00:12:46,230 --> 00:12:44,160 complexity how do you get the rover off 372 00:12:48,389 --> 00:12:46,240 and self-writing 373 00:12:49,910 --> 00:12:48,399 so someone at this meeting 374 00:12:51,190 --> 00:12:49,920 i've interviewed six people all six 375 00:12:52,550 --> 00:12:51,200 people in the room no one will take 376 00:12:55,430 --> 00:12:52,560 credit for this 377 00:12:56,790 --> 00:12:55,440 or assign blame um and and by the way 378 00:12:58,949 --> 00:12:56,800 while i've presented this as kind of a 379 00:13:00,310 --> 00:12:58,959 jpl story the reality is a very senior 380 00:13:01,990 --> 00:13:00,320 lockheed engineer by the name of steve 381 00:13:03,829 --> 00:13:02,000 jolly was in this as well and i've 382 00:13:05,269 --> 00:13:03,839 interviewed him too someone comes up 383 00:13:08,069 --> 00:13:05,279 with the idea was why we don't just 384 00:13:09,910 --> 00:13:08,079 dispense with the darn airbags 385 00:13:12,150 --> 00:13:09,920 and the reason and they don't and the 386 00:13:14,310 --> 00:13:12,160 reason they decide they can't yet is 387 00:13:17,110 --> 00:13:14,320 they can't answer this problem that's 388 00:13:22,550 --> 00:13:18,870 that's what's known as a controllability 389 00:13:23,750 --> 00:13:22,560 problem they didn't understand 390 00:13:25,430 --> 00:13:23,760 an answer to the question is what 391 00:13:27,670 --> 00:13:25,440 happens if the rover starts to swing in 392 00:13:29,750 --> 00:13:27,680 the wind on its way down to the surface 393 00:13:31,829 --> 00:13:29,760 can any reasonable control system handle 394 00:13:33,670 --> 00:13:31,839 that and the answer actually was yes but 395 00:13:35,030 --> 00:13:33,680 they didn't know it because the people 396 00:13:37,430 --> 00:13:35,040 in the room were mostly mechanical 397 00:13:39,430 --> 00:13:37,440 engineers a systems engineer 398 00:13:40,790 --> 00:13:39,440 and a program manager they weren't 399 00:13:42,230 --> 00:13:40,800 aeronautical engineers and they 400 00:13:43,189 --> 00:13:42,240 certainly weren't guidance and control 401 00:13:46,389 --> 00:13:43,199 people 402 00:13:48,870 --> 00:13:46,399 so they shoved this idea and baselined 403 00:13:51,509 --> 00:13:48,880 the other two to go forward into the 404 00:13:53,350 --> 00:13:51,519 next set of studies in fact the favored 405 00:13:55,430 --> 00:13:53,360 sample that came out of this was the 406 00:13:58,389 --> 00:13:55,440 pallet lander and here you see a later 407 00:14:00,069 --> 00:13:58,399 slide um from the an early phase of what 408 00:14:03,910 --> 00:14:00,079 becomes known as the mars smartlander 409 00:14:07,590 --> 00:14:05,750 planning a new mars program that's going 410 00:14:09,189 --> 00:14:07,600 on at the engineering level while ferris 411 00:14:11,350 --> 00:14:09,199 dairy and scott hubbard and some others 412 00:14:14,310 --> 00:14:11,360 are trying to plan a new program to 413 00:14:16,470 --> 00:14:14,320 replace the now dead surveyor program 414 00:14:18,389 --> 00:14:16,480 at jpl a physicist by the name of mark 415 00:14:20,389 --> 00:14:18,399 adler proposed this mission the mars 416 00:14:21,990 --> 00:14:20,399 mobile pathfinder that slo that actually 417 00:14:23,750 --> 00:14:22,000 very quickly floats to the top was 418 00:14:25,110 --> 00:14:23,760 proposed first in may 419 00:14:27,189 --> 00:14:25,120 and finally approved as the mars 420 00:14:28,470 --> 00:14:27,199 exploration rover mission in august of 421 00:14:29,910 --> 00:14:28,480 2000 422 00:14:31,189 --> 00:14:29,920 i don't know how they managed to do it 423 00:14:33,269 --> 00:14:31,199 but mark spokes forgot to put the 424 00:14:35,750 --> 00:14:33,279 airbags on um 425 00:14:37,509 --> 00:14:35,760 but that goes forward and becomes the 426 00:14:38,949 --> 00:14:37,519 short-range solution of what do we do 427 00:14:42,069 --> 00:14:38,959 next for mars 428 00:14:43,509 --> 00:14:42,079 longer term they create this program 429 00:14:45,430 --> 00:14:43,519 again we have the mars exploration 430 00:14:47,269 --> 00:14:45,440 rovers down here and now we have this 431 00:14:48,949 --> 00:14:47,279 thing called the mars smart landing 432 00:14:50,870 --> 00:14:48,959 smartlander is that pallet lander you 433 00:14:52,550 --> 00:14:50,880 saw before its initial purpose was 434 00:14:54,230 --> 00:14:52,560 simply to demonstrate that you can land 435 00:14:56,550 --> 00:14:54,240 a very large payload this thousand 436 00:14:59,509 --> 00:14:56,560 kilogram thing for sample return on the 437 00:15:01,030 --> 00:14:59,519 surface safely they didn't yet conceive 438 00:15:03,189 --> 00:15:01,040 it because again there's largely 439 00:15:05,189 --> 00:15:03,199 engineers as a high science return 440 00:15:07,990 --> 00:15:05,199 mission and then following the smart 441 00:15:12,629 --> 00:15:08,000 lander proving that 442 00:15:16,069 --> 00:15:14,150 um also on this you see the mars 443 00:15:17,910 --> 00:15:16,079 reconnaissance orbiter that mission has 444 00:15:19,670 --> 00:15:17,920 a engineering purpose i'm sure you've 445 00:15:22,310 --> 00:15:19,680 all heard about its scientific purpose 446 00:15:24,230 --> 00:15:22,320 but it's important to to illuminate one 447 00:15:26,949 --> 00:15:24,240 of the questions about 448 00:15:28,550 --> 00:15:26,959 how to land more safely on mars at jpl 449 00:15:30,470 --> 00:15:28,560 there's been a long-standing conflict 450 00:15:33,430 --> 00:15:30,480 between the advanced technology sections 451 00:15:36,629 --> 00:15:33,440 and the flight sections over how to make 452 00:15:38,870 --> 00:15:36,639 for a a more a safer landing there's an 453 00:15:40,470 --> 00:15:38,880 active hazard avoidance group at the lab 454 00:15:42,230 --> 00:15:40,480 who wants the spacecraft to look down 455 00:15:43,910 --> 00:15:42,240 see what's going on figure out for 456 00:15:46,069 --> 00:15:43,920 itself what to do 457 00:15:47,670 --> 00:15:46,079 and another faction at the lab who 458 00:15:51,030 --> 00:15:47,680 thinks that's a horrible awful idea 459 00:15:53,509 --> 00:15:51,040 because our rules require every possible 460 00:15:54,550 --> 00:15:53,519 decision that the lander can make to be 461 00:15:56,310 --> 00:15:54,560 tested 462 00:15:57,829 --> 00:15:56,320 and as the number of options increase in 463 00:16:00,150 --> 00:15:57,839 the mars surface is complicated as you 464 00:16:01,910 --> 00:16:00,160 heard from richard the option space for 465 00:16:04,069 --> 00:16:01,920 its selection becomes infinite and your 466 00:16:05,430 --> 00:16:04,079 test program becomes enormous 467 00:16:07,749 --> 00:16:05,440 so 468 00:16:10,069 --> 00:16:07,759 the mro that comes out of this has the 469 00:16:12,230 --> 00:16:10,079 engineering purpose 470 00:16:13,990 --> 00:16:12,240 of that's the large camera that's to do 471 00:16:15,829 --> 00:16:14,000 this is to photograph the surface at 472 00:16:17,350 --> 00:16:15,839 such high resolution that they will be 473 00:16:19,829 --> 00:16:17,360 able to find places that simply don't 474 00:16:22,790 --> 00:16:19,839 have any hazards to worry about and thus 475 00:16:24,710 --> 00:16:22,800 this hazard problem is solved 476 00:16:26,550 --> 00:16:24,720 with the smartlander 477 00:16:28,710 --> 00:16:26,560 so i said that the part pallet lander 478 00:16:30,710 --> 00:16:28,720 was the became the baseline for the 479 00:16:32,629 --> 00:16:30,720 smart lander program this is one of the 480 00:16:35,749 --> 00:16:32,639 test models of tom rolini the engineer 481 00:16:37,910 --> 00:16:35,759 assigned to figure out this pallet thing 482 00:16:39,509 --> 00:16:37,920 very quickly though 483 00:16:41,350 --> 00:16:39,519 the smart lander ceases to be a 484 00:16:43,590 --> 00:16:41,360 technology development man 485 00:16:46,230 --> 00:16:43,600 program and becomes a high science 486 00:16:47,749 --> 00:16:46,240 return mission a science 487 00:16:50,230 --> 00:16:47,759 definition team was put had been put 488 00:16:51,749 --> 00:16:50,240 together when they concluded they came 489 00:16:53,670 --> 00:16:51,759 out with an argument for making the 490 00:16:55,990 --> 00:16:53,680 smart lander the capstone scientific 491 00:16:57,749 --> 00:16:56,000 mission for the decade 492 00:17:00,389 --> 00:16:57,759 which meant uh an expansion of the 493 00:17:01,749 --> 00:17:00,399 budget from the project from the 750 494 00:17:03,590 --> 00:17:01,759 million dollar smart lander to the 495 00:17:06,230 --> 00:17:03,600 billion and a half dollar science 496 00:17:08,230 --> 00:17:06,240 laboratory and the name was changed too 497 00:17:10,710 --> 00:17:08,240 at the same time well a little bit after 498 00:17:14,309 --> 00:17:10,720 this goat happens they the engineers 499 00:17:15,590 --> 00:17:14,319 revisit this selection of the pallet 500 00:17:17,029 --> 00:17:15,600 they do it because they learned a lot 501 00:17:18,230 --> 00:17:17,039 during the mars exploration rover 502 00:17:20,390 --> 00:17:18,240 mission one thing they learned is that 503 00:17:22,069 --> 00:17:20,400 this control problem is not a problem 504 00:17:23,829 --> 00:17:22,079 there are solutions for it they could 505 00:17:24,789 --> 00:17:23,839 get them they could essentially buy them 506 00:17:26,230 --> 00:17:24,799 they'd been solved by other 507 00:17:27,829 --> 00:17:26,240 organizations 508 00:17:30,070 --> 00:17:27,839 they discovered this in all the testing 509 00:17:33,029 --> 00:17:30,080 program that they did for murr that they 510 00:17:34,710 --> 00:17:33,039 had not done very much of for 511 00:17:36,710 --> 00:17:34,720 for pathfinder 512 00:17:38,710 --> 00:17:36,720 they also become much more afraid of 513 00:17:40,549 --> 00:17:38,720 this egress problem the picture over 514 00:17:42,789 --> 00:17:40,559 here of one of the 515 00:17:44,470 --> 00:17:42,799 rover prototypes with the lander hung up 516 00:17:46,950 --> 00:17:44,480 on a rock 517 00:17:49,590 --> 00:17:46,960 mortified them because very often they 518 00:17:50,870 --> 00:17:49,600 had these rovers simply flop 519 00:17:53,190 --> 00:17:50,880 which would have been a very expensive 520 00:17:54,789 --> 00:17:53,200 and embarrassing mission failure on the 521 00:17:56,870 --> 00:17:54,799 day of landing 522 00:17:58,549 --> 00:17:56,880 um so this egress challenge rose in 523 00:18:00,390 --> 00:17:58,559 their minds to be a much worse problem 524 00:18:02,710 --> 00:18:00,400 than this controllability problem sort 525 00:18:05,430 --> 00:18:02,720 of design review in 2004 526 00:18:07,510 --> 00:18:05,440 they revisit this up trade space as they 527 00:18:10,150 --> 00:18:07,520 call it and eventually come back to the 528 00:18:11,350 --> 00:18:10,160 conclusion that they had rejected before 529 00:18:14,710 --> 00:18:11,360 that they should just get rid of the 530 00:18:17,029 --> 00:18:14,720 bloody airbags and the lander and land 531 00:18:19,669 --> 00:18:17,039 straight on the wheels 532 00:18:21,430 --> 00:18:19,679 the demise of sample return 533 00:18:24,470 --> 00:18:21,440 i commented earlier today and i'm 534 00:18:27,990 --> 00:18:26,230 nasa has tried repeatedly to develop a 535 00:18:29,750 --> 00:18:28,000 new punch vehicle and it has not 536 00:18:31,669 --> 00:18:29,760 succeeded at it 537 00:18:33,430 --> 00:18:31,679 those are the first those are four 538 00:18:35,990 --> 00:18:33,440 here's the fifth one in the vision for 539 00:18:37,590 --> 00:18:36,000 space exploration 540 00:18:38,870 --> 00:18:37,600 it was called aries you probably all 541 00:18:39,669 --> 00:18:38,880 remember it because it's not that long 542 00:18:41,029 --> 00:18:39,679 ago 543 00:18:43,669 --> 00:18:41,039 it was supposed to 544 00:18:45,029 --> 00:18:43,679 be the basis for sending humans back to 545 00:18:46,390 --> 00:18:45,039 mars 546 00:18:48,470 --> 00:18:46,400 but it was not it was supposed to be 547 00:18:50,710 --> 00:18:48,480 funded by an increase in the nasa budget 548 00:18:52,630 --> 00:18:50,720 of about three billion per year plus the 549 00:18:53,830 --> 00:18:52,640 shutdown federal which goes down at this 550 00:18:55,029 --> 00:18:53,840 point 551 00:18:56,789 --> 00:18:55,039 that three billion a year never 552 00:18:58,789 --> 00:18:56,799 materialized nasa actually got about a 553 00:19:00,710 --> 00:18:58,799 billion and a half and what happened 554 00:19:02,950 --> 00:19:00,720 around headquarters is that they then 555 00:19:05,270 --> 00:19:02,960 went looking around for donations from 556 00:19:07,350 --> 00:19:05,280 the other programs to 557 00:19:09,510 --> 00:19:07,360 finish constellation 558 00:19:12,070 --> 00:19:09,520 the mars program was told in may 2005 559 00:19:13,830 --> 00:19:12,080 that its contribution to constellation 560 00:19:15,990 --> 00:19:13,840 would be about three billion dollars 561 00:19:17,190 --> 00:19:16,000 over the next five years 562 00:19:18,630 --> 00:19:17,200 which 563 00:19:20,310 --> 00:19:18,640 looks like this 564 00:19:25,430 --> 00:19:20,320 this was the budget they were expecting 565 00:19:29,830 --> 00:19:27,830 that actually was cut even worse 566 00:19:31,029 --> 00:19:29,840 so the sample return 567 00:19:33,190 --> 00:19:31,039 went away 568 00:19:34,630 --> 00:19:33,200 as one aviation week reporter a cut of 569 00:19:36,630 --> 00:19:34,640 this magnitude 570 00:19:39,750 --> 00:19:36,640 pushed temple return off the table and 571 00:19:41,110 --> 00:19:39,760 onto the floor 572 00:19:44,310 --> 00:19:41,120 so i probably don't have much time for 573 00:20:02,230 --> 00:19:44,320 conclusions or ruminations but 574 00:20:02,240 --> 00:20:15,590 oh 575 00:20:19,029 --> 00:20:16,710 so 576 00:20:22,149 --> 00:20:19,039 i mentioned the schizophrenia of nasa 577 00:20:24,230 --> 00:20:22,159 that it's both a scientific agency 578 00:20:26,470 --> 00:20:24,240 doing a lots of doing sciences across 579 00:20:28,470 --> 00:20:26,480 many different disciplines and an agency 580 00:20:31,430 --> 00:20:28,480 that seizes its mission the human 581 00:20:33,990 --> 00:20:31,440 colonization of the solar system i think 582 00:20:36,230 --> 00:20:34,000 um and as you've seen just in my talk 583 00:20:37,669 --> 00:20:36,240 but in some of the other talks these two 584 00:20:39,430 --> 00:20:37,679 things sometimes 585 00:20:41,909 --> 00:20:39,440 work together pretty well and other 586 00:20:43,510 --> 00:20:41,919 times they rate each other's budgets 587 00:20:46,230 --> 00:20:43,520 and so there's a constant conflict 588 00:20:48,710 --> 00:20:46,240 around nasa that i often have to explain 589 00:20:51,190 --> 00:20:48,720 to audiences the science directorate in 590 00:20:52,710 --> 00:20:51,200 my view plays sort of a round-robin game 591 00:20:55,029 --> 00:20:52,720 since it never gets as much money for 592 00:20:57,350 --> 00:20:55,039 all its ambitions it feeds some things 593 00:21:00,070 --> 00:20:57,360 well for a while and starves others and 594 00:21:02,630 --> 00:21:00,080 that circle always goes around and so 595 00:21:04,390 --> 00:21:02,640 one of my ruminations is is it ever 596 00:21:06,630 --> 00:21:04,400 going to be possible to do sample return 597 00:21:08,390 --> 00:21:06,640 given how much it's going to cost 598 00:21:10,789 --> 00:21:08,400 because you can't sustain a funding 599 00:21:12,710 --> 00:21:10,799 profile in the science directorate for 600 00:21:14,230 --> 00:21:12,720 more than three or four years and that's 601 00:21:15,750 --> 00:21:14,240 not enough time to get sample return 602 00:21:18,710 --> 00:21:15,760 done on the amount of 603 00:21:21,190 --> 00:21:18,720 of peak budget that's available 604 00:21:22,630 --> 00:21:21,200 so that's one of my questions 605 00:21:24,470 --> 00:21:22,640 and i can't answer it because of course 606 00:21:25,830 --> 00:21:24,480 as a historian i only deal with the past 607 00:21:27,270 --> 00:21:25,840 it's jim green's job to deal with the 608 00:21:29,110 --> 00:21:27,280 future 609 00:21:31,029 --> 00:21:29,120 but i wonder about that 610 00:21:33,430 --> 00:21:31,039 so that's one of my ruminations another 611 00:21:35,029 --> 00:21:33,440 i'm in the reason i picked this subject 612 00:21:36,630 --> 00:21:35,039 and mars exploration overall from an 613 00:21:38,230 --> 00:21:36,640 engineering perspective is i'm 614 00:21:39,909 --> 00:21:38,240 interested in the way engineers take 615 00:21:41,029 --> 00:21:39,919 lessons from one project forward to the 616 00:21:42,870 --> 00:21:41,039 next one 617 00:21:44,390 --> 00:21:42,880 if i had more time i would tell you that 618 00:21:46,070 --> 00:21:44,400 the folks who were on this bubble team 619 00:21:48,230 --> 00:21:46,080 study were almost all pathfinder people 620 00:21:49,750 --> 00:21:48,240 except for steve jolly from lockheed 621 00:21:52,070 --> 00:21:49,760 who was involved with the global 622 00:21:53,510 --> 00:21:52,080 surveyor and uh 623 00:21:54,470 --> 00:21:53,520 sorry polar lander missions to some 624 00:21:56,789 --> 00:21:54,480 degree 625 00:21:59,990 --> 00:21:56,799 um and so their experience the reason 626 00:22:02,710 --> 00:22:00,000 they had one that bubble team 627 00:22:05,350 --> 00:22:02,720 study came from the pathfinder gang's 628 00:22:07,270 --> 00:22:05,360 experience and then after they all get 629 00:22:09,909 --> 00:22:07,280 drafted into the mars exploration rover 630 00:22:11,590 --> 00:22:09,919 mission it gets reinformed by that that 631 00:22:13,270 --> 00:22:11,600 was suggested in here but not made 632 00:22:15,029 --> 00:22:13,280 terribly clear because i'm in enough of 633 00:22:18,549 --> 00:22:15,039 a hurry to get off the stage 634 00:22:20,950 --> 00:22:18,559 oh and i see i guess i have a question 635 00:22:24,310 --> 00:22:20,960 nobody i decided to be 636 00:22:30,710 --> 00:22:26,950 are you going to return sample from some 637 00:22:35,270 --> 00:22:30,720 specific landing site or just to collect 638 00:22:39,270 --> 00:22:38,149 area around the landing site with the 639 00:22:41,830 --> 00:22:39,280 capable 640 00:22:44,230 --> 00:22:41,840 rover equipped with manipulator and 641 00:22:46,630 --> 00:22:44,240 possibly even drilling in order just to 642 00:22:48,310 --> 00:22:46,640 return deep-seated 643 00:22:50,070 --> 00:22:48,320 you know probes 644 00:22:51,830 --> 00:22:50,080 oh i guess the answer is that jim green 645 00:22:54,549 --> 00:22:51,840 has to answer that question what the 646 00:22:56,470 --> 00:22:54,559 scientists clearly want the most is a 647 00:22:58,710 --> 00:22:56,480 long range rover they can go hundreds of 648 00:23:00,630 --> 00:22:58,720 kilometers collect many samples from 649 00:23:02,149 --> 00:23:00,640 many different terrains if they can 650 00:23:03,350 --> 00:23:02,159 figure out how to do it a drill that 651 00:23:04,950 --> 00:23:03,360 will actually pull them up i think 652 00:23:06,710 --> 00:23:04,960 there's a drill on curiosity but i don't 653 00:23:08,549 --> 00:23:06,720 know what its capability is 654 00:23:10,549 --> 00:23:08,559 because i only study the past so that's 655 00:23:12,950 --> 00:23:10,559 clearly what they want what they're 656 00:23:14,950 --> 00:23:12,960 going to get is whatever the science 657 00:23:16,789 --> 00:23:14,960 director can afford 658 00:23:19,110 --> 00:23:16,799 which might be nothing more than the 659 00:23:21,270 --> 00:23:19,120 grab sampling i just don't know again i 660 00:23:23,110 --> 00:23:21,280 deal with the past not the future 661 00:23:24,710 --> 00:23:23,120 but i think that's that's your trade 662 00:23:26,789 --> 00:23:24,720 space there's what the scientists want 663 00:23:28,950 --> 00:23:26,799 so part of my story is ambition and then 664 00:23:31,669 --> 00:23:28,960 there's what we're actually able to get 665 00:23:33,830 --> 00:23:31,679 out of congress to pay for um and that's 666 00:23:36,870 --> 00:23:33,840 the other end of the the 667 00:23:41,029 --> 00:23:38,710 heidi hamill from aura 668 00:23:43,029 --> 00:23:41,039 i can think of an astrophysics example 669 00:23:44,390 --> 00:23:43,039 where it has benefited from its 670 00:23:46,310 --> 00:23:44,400 interaction with human space flight 671 00:23:48,549 --> 00:23:46,320 program and that would be hubble 672 00:23:50,149 --> 00:23:48,559 which we serviced a thousand times 673 00:23:51,029 --> 00:23:50,159 that's an exaggeration but you get the 674 00:23:54,390 --> 00:23:51,039 idea 675 00:23:56,149 --> 00:23:54,400 um but i'm i'm struggling to s five 676 00:23:58,149 --> 00:23:56,159 actually right um 677 00:24:01,430 --> 00:23:58,159 there is one was twice well uh but i'm 678 00:24:04,230 --> 00:24:01,440 struggling to think of ones that 679 00:24:06,710 --> 00:24:04,240 where the planetary science community 680 00:24:09,750 --> 00:24:06,720 benefited from interactions with the 681 00:24:13,269 --> 00:24:09,760 human space flight program can you 682 00:24:15,990 --> 00:24:13,279 can you think of some or some examples 683 00:24:18,470 --> 00:24:16,000 a small degree 684 00:24:20,390 --> 00:24:18,480 mars 01 project 685 00:24:22,549 --> 00:24:20,400 had some instruments 686 00:24:24,070 --> 00:24:22,559 uh that were supposed to contribute to 687 00:24:25,510 --> 00:24:24,080 the human program 688 00:24:26,950 --> 00:24:25,520 the reason i'm not willing to say that's 689 00:24:28,549 --> 00:24:26,960 an unalloyed good is that the human 690 00:24:29,590 --> 00:24:28,559 program ultimately wasn't willing to pay 691 00:24:31,269 --> 00:24:29,600 for them 692 00:24:33,350 --> 00:24:31,279 and 693 00:24:35,190 --> 00:24:33,360 folks at headquarters had to go begging 694 00:24:37,190 --> 00:24:35,200 around congress to get some extra money 695 00:24:39,190 --> 00:24:37,200 in order to actually put them on the 696 00:24:40,310 --> 00:24:39,200 vehicles and then of course the lander 697 00:24:42,710 --> 00:24:40,320 was cancelled 698 00:24:44,549 --> 00:24:42,720 so only the i think it's the marie 699 00:24:47,830 --> 00:24:44,559 instrument on the odyssey orbiter the 700 00:24:49,909 --> 00:24:47,840 2001 orbiter actually flies um and 701 00:24:51,590 --> 00:24:49,919 that's uh that's clearly a contribution 702 00:24:53,590 --> 00:24:51,600 to understanding mars well enough to 703 00:24:54,870 --> 00:24:53,600 send people there um 704 00:24:55,750 --> 00:24:54,880 it but it's 705 00:25:00,789 --> 00:24:55,760 it's 706 00:25:02,630 --> 00:25:00,799 example as hubble is um which you're 707 00:25:04,149 --> 00:25:02,640 right clearly benefited from being 708 00:25:06,149 --> 00:25:04,159 shuttle serviceable because the 709 00:25:08,310 --> 00:25:06,159 planetary stuff because we send it 710 00:25:09,750 --> 00:25:08,320 off and don't get it back um there 711 00:25:11,029 --> 00:25:09,760 hasn't been quite that strength of 712 00:25:12,789 --> 00:25:11,039 interaction 713 00:25:35,830 --> 00:25:12,799 to my knowledge 714 00:25:39,750 --> 00:25:37,909 yeah that's right so he's talking about 715 00:25:41,029 --> 00:25:39,760 the surveyor lander program for which 716 00:25:42,950 --> 00:25:41,039 there hasn't been history written and 717 00:25:43,909 --> 00:25:42,960 i've actually came out here early to dig 718 00:25:45,350 --> 00:25:43,919 through some of 719 00:25:47,350 --> 00:25:45,360 the records from that because that's the 720 00:25:49,029 --> 00:25:47,360 next project i want or program really 721 00:25:53,750 --> 00:25:49,039 that i want to write about it 722 00:25:53,760 --> 00:26:01,190 else 723 00:26:04,230 --> 00:26:02,470 fabulous so we've heard about the 724 00:26:05,430 --> 00:26:04,240 missions the science the engineering and 725 00:26:06,870 --> 00:26:05,440 now let's take a turn towards 726 00:26:09,269 --> 00:26:06,880 headquarters and those people behind the 727 00:26:10,710 --> 00:26:09,279 scenes so harry lambright is professor 728 00:26:12,149 --> 00:26:10,720 of public administration and 729 00:26:13,350 --> 00:26:12,159 international affairs and political 730 00:26:15,669 --> 00:26:13,360 science at the maxwell school of 731 00:26:17,669 --> 00:26:15,679 syracuse university he's authored many 732 00:26:19,750 --> 00:26:17,679 works including a biography of james 733 00:26:21,590 --> 00:26:19,760 webb called powering apollo and his 734 00:26:23,669 --> 00:26:21,600 editor of space policy in the 21st 735 00:26:25,190 --> 00:26:23,679 century harry is also a fellow of the 736 00:26:27,029 --> 00:26:25,200 american association for the advancement 737 00:26:36,470 --> 00:26:27,039 of science and the national academy of 738 00:26:42,070 --> 00:26:39,190 well i wish i had some pretty pictures 739 00:26:44,310 --> 00:26:42,080 of men at least but uh i don't though we 740 00:26:46,390 --> 00:26:44,320 have what four administrators sitting 741 00:26:48,310 --> 00:26:46,400 behind desks and suits i don't think 742 00:26:50,710 --> 00:26:48,320 would go over very well with this 743 00:26:53,029 --> 00:26:50,720 audience 744 00:26:54,710 --> 00:26:53,039 so or so nate if i tried it out on a 745 00:26:58,230 --> 00:26:54,720 female graduate student and she said 746 00:27:00,630 --> 00:26:59,669 well anyway i'm going to talk about 747 00:27:02,789 --> 00:27:00,640 people 748 00:27:04,950 --> 00:27:02,799 uh you you said are individuals 749 00:27:07,830 --> 00:27:04,960 important uh yes of course they are but 750 00:27:08,630 --> 00:27:07,840 the nasa administrator is important 751 00:27:10,950 --> 00:27:08,640 it's 752 00:27:14,149 --> 00:27:10,960 an interesting question i had occasion 753 00:27:17,190 --> 00:27:14,159 to interview a scientist 754 00:27:19,669 --> 00:27:17,200 at jpl named dan mclease who was told me 755 00:27:22,630 --> 00:27:19,679 about experience he had with dan golden 756 00:27:25,269 --> 00:27:22,640 after the meteorite 757 00:27:27,029 --> 00:27:25,279 situation in 1996 758 00:27:29,350 --> 00:27:27,039 dan golden 759 00:27:31,269 --> 00:27:29,360 was very excited about the meteorite 760 00:27:33,909 --> 00:27:31,279 and he wanted to know from the 761 00:27:35,669 --> 00:27:33,919 scientists what is what's the next step 762 00:27:37,430 --> 00:27:35,679 what's the next step what do we do next 763 00:27:38,470 --> 00:27:37,440 and they said well the only way you're 764 00:27:41,190 --> 00:27:38,480 going to find out if you're going to 765 00:27:44,230 --> 00:27:41,200 have life is mars sample return he said 766 00:27:46,870 --> 00:27:44,240 great let's do it now 767 00:27:49,110 --> 00:27:46,880 and he kept pressing them for given 768 00:27:51,510 --> 00:27:49,120 particular years and all of them work 769 00:27:53,190 --> 00:27:51,520 you know sinus said we can't just send 770 00:27:54,310 --> 00:27:53,200 something up there we've got to know 771 00:27:56,789 --> 00:27:54,320 where to go 772 00:27:59,510 --> 00:27:56,799 and they reminded him of viking where 773 00:28:01,190 --> 00:27:59,520 the answer had come out and it had hurt 774 00:28:02,870 --> 00:28:01,200 the program so we've got to be 775 00:28:04,310 --> 00:28:02,880 systematic 776 00:28:06,149 --> 00:28:04,320 incremental 777 00:28:09,269 --> 00:28:06,159 comprehensive et cetera et cetera et 778 00:28:11,510 --> 00:28:09,279 cetera he said fine okay do what's right 779 00:28:15,110 --> 00:28:11,520 by science but remember 780 00:28:18,710 --> 00:28:15,120 the pace will be determined by politics 781 00:28:20,070 --> 00:28:18,720 true now how does it it seems to me the 782 00:28:22,470 --> 00:28:20,080 role of the science the role of the 783 00:28:24,630 --> 00:28:22,480 administrator the nasa administrator is 784 00:28:27,029 --> 00:28:24,640 somehow to 785 00:28:28,950 --> 00:28:27,039 sort of cross those boundaries between 786 00:28:31,830 --> 00:28:28,960 the worlds of science and technology and 787 00:28:34,230 --> 00:28:31,840 nasa and the worlds of politics in the 788 00:28:36,230 --> 00:28:34,240 vernacular of political science 789 00:28:37,590 --> 00:28:36,240 the nasa administrator falls into a 790 00:28:40,070 --> 00:28:37,600 class of people that are called 791 00:28:41,990 --> 00:28:40,080 political executives what that means 792 00:28:44,710 --> 00:28:42,000 essentially is they are executives that 793 00:28:47,590 --> 00:28:44,720 is they run organizations they have 794 00:28:49,430 --> 00:28:47,600 executive jobs they deal with personnel 795 00:28:51,430 --> 00:28:49,440 they deal with budgets they deal with 796 00:28:53,990 --> 00:28:51,440 organizations and reorganizations but 797 00:28:56,389 --> 00:28:54,000 they're politicians that is to say they 798 00:28:58,870 --> 00:28:56,399 are appointed by the president and 799 00:29:01,110 --> 00:28:58,880 confirmed by the senate and are expected 800 00:29:02,470 --> 00:29:01,120 to play advocacy roles on behalf of 801 00:29:04,549 --> 00:29:02,480 their agencies 802 00:29:06,870 --> 00:29:04,559 so they have inside jobs 803 00:29:08,870 --> 00:29:06,880 and they have outside jobs and they have 804 00:29:10,470 --> 00:29:08,880 to do them both 805 00:29:12,389 --> 00:29:10,480 to be effective 806 00:29:14,310 --> 00:29:12,399 as as administrators 807 00:29:17,350 --> 00:29:14,320 and this is this has always been the 808 00:29:18,230 --> 00:29:17,360 case and some are more effective than 809 00:29:19,110 --> 00:29:18,240 others 810 00:29:27,029 --> 00:29:19,120 uh 811 00:29:29,269 --> 00:29:27,039 it takes to be effective in both of 812 00:29:31,750 --> 00:29:29,279 those roles and to combine them in one 813 00:29:34,389 --> 00:29:31,760 man it's rare there aren't really many 814 00:29:37,830 --> 00:29:34,399 people at nasa or other places who have 815 00:29:40,549 --> 00:29:37,840 had the the gifts that go with playing 816 00:29:42,950 --> 00:29:40,559 that kind of total role the closest you 817 00:29:44,310 --> 00:29:42,960 come at nasa was james webb 818 00:29:47,510 --> 00:29:44,320 and uh 819 00:29:48,310 --> 00:29:47,520 there is a fascinating uh story about 820 00:29:50,389 --> 00:29:48,320 webb 821 00:29:52,310 --> 00:29:50,399 and playing that role and it's coming 822 00:29:55,029 --> 00:29:52,320 out with the kennedy tapes 823 00:29:55,830 --> 00:29:55,039 when in the early days of apollo 824 00:29:58,789 --> 00:29:55,840 the 825 00:30:01,350 --> 00:29:58,799 president kennedy uh was dealing with a 826 00:30:03,669 --> 00:30:01,360 dispute a power struggle within nasa 827 00:30:06,870 --> 00:30:03,679 between the head of the human space 828 00:30:09,909 --> 00:30:06,880 space program human space flight program 829 00:30:11,990 --> 00:30:09,919 who wanted all the money for apollo and 830 00:30:13,510 --> 00:30:12,000 webb who wanted some of the money to go 831 00:30:16,070 --> 00:30:13,520 to the science program that he was 832 00:30:18,070 --> 00:30:16,080 beginning to build up and it came to 833 00:30:19,510 --> 00:30:18,080 kennedy at the end of the day to make 834 00:30:21,830 --> 00:30:19,520 the decision 835 00:30:24,310 --> 00:30:21,840 in kennedy and this is something that 836 00:30:26,630 --> 00:30:24,320 bothers a lot of people basically said i 837 00:30:28,549 --> 00:30:26,640 don't really care that much about space 838 00:30:29,750 --> 00:30:28,559 or science i care about beating the 839 00:30:31,029 --> 00:30:29,760 russians 840 00:30:33,269 --> 00:30:31,039 and uh 841 00:30:36,149 --> 00:30:33,279 webb had to make the point that apollo 842 00:30:38,870 --> 00:30:36,159 was a means to an end at the end was 843 00:30:41,590 --> 00:30:38,880 preeminence leadership 844 00:30:43,909 --> 00:30:41,600 and he said sciences is also that way 845 00:30:45,669 --> 00:30:43,919 science is a means to an end the end 846 00:30:48,789 --> 00:30:45,679 being preeminence 847 00:30:50,789 --> 00:30:48,799 not apollo for its so to say and he and 848 00:30:53,029 --> 00:30:50,799 kennedy said well i want you to uh i'm 849 00:30:54,710 --> 00:30:53,039 not sure we're on the same wavelength 850 00:30:56,630 --> 00:30:54,720 you go back and write me a memo and 851 00:30:59,430 --> 00:30:56,640 explain what you're talking about 852 00:31:01,269 --> 00:30:59,440 and he did that and 853 00:31:03,590 --> 00:31:01,279 we have never heard back 854 00:31:05,590 --> 00:31:03,600 uh and as a result the head of the 855 00:31:09,029 --> 00:31:05,600 apollo program was fired 856 00:31:12,470 --> 00:31:10,950 he bridged the gap 857 00:31:14,230 --> 00:31:12,480 he explained to the president why 858 00:31:15,909 --> 00:31:14,240 science was important 859 00:31:17,110 --> 00:31:15,919 and science continues and we're here 860 00:31:18,950 --> 00:31:17,120 today 861 00:31:20,870 --> 00:31:18,960 now 862 00:31:22,389 --> 00:31:20,880 there aren't many people who can do that 863 00:31:24,630 --> 00:31:22,399 i found actually one person in 864 00:31:27,430 --> 00:31:24,640 washington today who seems to have those 865 00:31:29,750 --> 00:31:27,440 skills if you want to see what it takes 866 00:31:32,070 --> 00:31:29,760 take a look at francis collins francis 867 00:31:34,230 --> 00:31:32,080 collins was head of the genome project 868 00:31:36,310 --> 00:31:34,240 and now he's head of nih 869 00:31:39,190 --> 00:31:36,320 and he seems to have those 870 00:31:40,870 --> 00:31:39,200 unusual combination of skills 871 00:31:42,950 --> 00:31:40,880 but they're rare and there aren't many 872 00:31:45,269 --> 00:31:42,960 and have been that many in nasa history 873 00:31:47,430 --> 00:31:45,279 who have had the blending that it takes 874 00:31:49,990 --> 00:31:47,440 to be both a solid and manager and a 875 00:31:52,310 --> 00:31:50,000 solid politician at the same time 876 00:31:54,789 --> 00:31:52,320 because most people don't have them in 877 00:31:56,549 --> 00:31:54,799 any event what i'm the what i'm going to 878 00:31:58,549 --> 00:31:56,559 talk about are 879 00:32:01,590 --> 00:31:58,559 our four guys 880 00:32:02,789 --> 00:32:01,600 as they relate to the mars program now 881 00:32:04,870 --> 00:32:02,799 in connection when you're dealing with 882 00:32:07,509 --> 00:32:04,880 the nasa administrator remember you're 883 00:32:09,750 --> 00:32:07,519 dealing like like with the equivalent of 884 00:32:13,350 --> 00:32:09,760 a ceo of a corporation or the president 885 00:32:15,110 --> 00:32:13,360 of a university they have many programs 886 00:32:17,990 --> 00:32:15,120 mars is just one of them 887 00:32:19,990 --> 00:32:18,000 and all in all all all nasa 888 00:32:21,269 --> 00:32:20,000 administrators have focused mainly on 889 00:32:22,870 --> 00:32:21,279 the human space 890 00:32:23,669 --> 00:32:22,880 program because that's where the money 891 00:32:25,830 --> 00:32:23,679 is 892 00:32:27,430 --> 00:32:25,840 and that's where most of the political 893 00:32:28,870 --> 00:32:27,440 issues are 894 00:32:31,029 --> 00:32:28,880 so mars 895 00:32:33,430 --> 00:32:31,039 so the question is how do how do how do 896 00:32:35,110 --> 00:32:33,440 astronaut ministers deal with mars 897 00:32:37,509 --> 00:32:35,120 well essentially they don't deal with it 898 00:32:38,710 --> 00:32:37,519 very much but they do deal with it once 899 00:32:40,310 --> 00:32:38,720 in a while 900 00:32:41,750 --> 00:32:40,320 and when they deal with it usually it's 901 00:32:43,190 --> 00:32:41,760 because they're dealing with the biggest 902 00:32:46,710 --> 00:32:43,200 decisions 903 00:32:48,870 --> 00:32:46,720 ultimately come up to the desk of the 904 00:32:51,110 --> 00:32:48,880 administrator and these are the biggest 905 00:32:54,070 --> 00:32:51,120 these are decisions like as in a human 906 00:32:57,029 --> 00:32:54,080 life they're the decisions of 907 00:32:59,830 --> 00:32:57,039 a program getting born a program being 908 00:33:02,310 --> 00:32:59,840 significantly reoriented or programmed 909 00:33:04,310 --> 00:33:02,320 to being terminated or being in danger 910 00:33:06,070 --> 00:33:04,320 of being terminated and that's where 911 00:33:08,149 --> 00:33:06,080 that's when nasa administrators get 912 00:33:11,029 --> 00:33:08,159 involved with science and get involved 913 00:33:12,070 --> 00:33:11,039 with with with mars in particular 914 00:33:14,149 --> 00:33:12,080 so 915 00:33:16,230 --> 00:33:14,159 we'll start with dan golden 916 00:33:18,789 --> 00:33:16,240 and golden uh 917 00:33:20,630 --> 00:33:18,799 uh you know was uh probably the most 918 00:33:22,870 --> 00:33:20,640 controversial 919 00:33:25,269 --> 00:33:22,880 nasa administrator in history 920 00:33:26,789 --> 00:33:25,279 uh and 921 00:33:28,710 --> 00:33:26,799 you can get a different view of dan 922 00:33:30,870 --> 00:33:28,720 golden depending on whether you're 923 00:33:33,590 --> 00:33:30,880 looking at dan golden and the shuttle 924 00:33:35,830 --> 00:33:33,600 program or the space station program or 925 00:33:38,070 --> 00:33:35,840 the mars program when it comes to the 926 00:33:39,350 --> 00:33:38,080 mars program i think dan golden looks 927 00:33:40,230 --> 00:33:39,360 pretty good 928 00:33:43,350 --> 00:33:40,240 now 929 00:33:46,070 --> 00:33:43,360 why do i say that well i say that is is 930 00:33:48,549 --> 00:33:46,080 that it is that he it was a passion for 931 00:33:49,509 --> 00:33:48,559 him he was genuinely interested in it we 932 00:33:51,509 --> 00:33:49,519 all know 933 00:33:54,470 --> 00:33:51,519 that when you deal with leaders it's a 934 00:33:56,149 --> 00:33:54,480 mix of personality and and situation we 935 00:33:58,149 --> 00:33:56,159 all know that now the question the 936 00:34:00,149 --> 00:33:58,159 personality of dan golden was was 937 00:34:02,710 --> 00:34:00,159 dynamic intense and 938 00:34:04,310 --> 00:34:02,720 intimidating for anyone who ever met at 939 00:34:08,149 --> 00:34:04,320 my first time ever met him i thought he 940 00:34:10,550 --> 00:34:08,159 was going to explode on me oh 941 00:34:11,909 --> 00:34:10,560 you got you got an hour he told me you 942 00:34:13,190 --> 00:34:11,919 got an hour 943 00:34:15,030 --> 00:34:13,200 boy i 944 00:34:16,149 --> 00:34:15,040 jumped up and i started asking questions 945 00:34:18,230 --> 00:34:16,159 real fast 946 00:34:21,909 --> 00:34:18,240 but that was dan golden and that was my 947 00:34:23,909 --> 00:34:21,919 introduction to him uh and uh next i'll 948 00:34:25,829 --> 00:34:23,919 say i'm so full of anecdotes on there 949 00:34:27,750 --> 00:34:25,839 and gold as i was leaving he grabbed me 950 00:34:30,389 --> 00:34:27,760 by the lapels and you know what's wrong 951 00:34:32,389 --> 00:34:30,399 with nasa nasa young guys don't work 952 00:34:33,990 --> 00:34:32,399 hard enough i was on an airplane at six 953 00:34:36,149 --> 00:34:34,000 in the morning and my guys were all 954 00:34:38,629 --> 00:34:36,159 sleeping well i was working hard 955 00:34:40,550 --> 00:34:38,639 and that was dan goldman anyway any of 956 00:34:42,950 --> 00:34:40,560 you know him you know this is this is 957 00:34:46,310 --> 00:34:42,960 dan gold intense man 958 00:34:48,869 --> 00:34:46,320 terribly intense and and and uh he loved 959 00:34:51,829 --> 00:34:48,879 mars 960 00:34:54,230 --> 00:34:51,839 he spent most of his time on the space 961 00:34:56,389 --> 00:34:54,240 station and the human space program 962 00:34:59,670 --> 00:34:56,399 human space flight program but what he 963 00:35:02,069 --> 00:34:59,680 loved was mars and it was a love affair 964 00:35:03,390 --> 00:35:02,079 he if you recall when he was hired back 965 00:35:05,109 --> 00:35:03,400 in 92 966 00:35:08,630 --> 00:35:05,119 1992 967 00:35:11,109 --> 00:35:08,640 bush one had had this moon mars program 968 00:35:13,030 --> 00:35:11,119 it didn't go anywhere but that's one of 969 00:35:14,950 --> 00:35:13,040 the reasons golden took the job he 970 00:35:17,750 --> 00:35:14,960 thought he wanted was going to run this 971 00:35:19,430 --> 00:35:17,760 moon mars program it was a human program 972 00:35:21,030 --> 00:35:19,440 he found out very quickly it wasn't 973 00:35:22,950 --> 00:35:21,040 going anywhere 974 00:35:25,670 --> 00:35:22,960 but he still wanted to do mars he still 975 00:35:26,950 --> 00:35:25,680 wanted to do mars and so he looked 976 00:35:29,670 --> 00:35:26,960 at mars 977 00:35:32,950 --> 00:35:29,680 as pre he looked it questioned about 978 00:35:35,670 --> 00:35:32,960 human and unmanned he looked at mars at 979 00:35:38,630 --> 00:35:35,680 from the standpoint of precursory to man 980 00:35:40,950 --> 00:35:38,640 space if i can't get a man program 981 00:35:43,109 --> 00:35:40,960 i can do what we did in the moon program 982 00:35:44,710 --> 00:35:43,119 which have a precursory program so 983 00:35:46,470 --> 00:35:44,720 that's how he saw it that's how a lot of 984 00:35:47,990 --> 00:35:46,480 administrators see it incidentally 985 00:35:49,349 --> 00:35:48,000 because they come at it from the human 986 00:35:51,190 --> 00:35:49,359 space program 987 00:35:53,270 --> 00:35:51,200 now 988 00:35:55,750 --> 00:35:53,280 the big decision he made 989 00:35:57,430 --> 00:35:55,760 came after mars observer 990 00:35:58,790 --> 00:35:57,440 he made he made a number of decisions 991 00:36:00,950 --> 00:35:58,800 but i'm going to deal just with what i 992 00:36:02,550 --> 00:36:00,960 think are the biggest ones first 993 00:36:04,710 --> 00:36:02,560 decision he made have to do with was 994 00:36:06,069 --> 00:36:04,720 after mars observer 995 00:36:09,190 --> 00:36:06,079 went down 996 00:36:11,510 --> 00:36:09,200 and and essentially uh 997 00:36:14,870 --> 00:36:11,520 oh he didn't want it to go 998 00:36:16,710 --> 00:36:14,880 he he spent time talking to his science 999 00:36:19,109 --> 00:36:16,720 at his science administrator who was 1000 00:36:22,630 --> 00:36:19,119 wesley huntress i think is sitting here 1001 00:36:24,150 --> 00:36:22,640 and i he talked to carl sagan oh no 10 1002 00:36:28,470 --> 00:36:24,160 minutes i've only gotten to start a 1003 00:36:32,069 --> 00:36:30,710 all right so here we go all right real 1004 00:36:33,829 --> 00:36:32,079 quick 1005 00:36:36,390 --> 00:36:33,839 basically what what happened is 1006 00:36:38,790 --> 00:36:36,400 essentially these decisions are made by 1007 00:36:41,190 --> 00:36:38,800 a hundred people but the guy who's in 1008 00:36:43,190 --> 00:36:41,200 charge at the bar at the top has to sign 1009 00:36:44,550 --> 00:36:43,200 off on them has to make the decision and 1010 00:36:46,790 --> 00:36:44,560 then he has to sell them to the 1011 00:36:49,109 --> 00:36:46,800 political community basically decisions 1012 00:36:51,589 --> 00:36:49,119 may be going we're going programmatic 1013 00:36:53,750 --> 00:36:51,599 not just a one-shot affair mars like 1014 00:36:55,430 --> 00:36:53,760 mars observer but a program with many 1015 00:36:57,990 --> 00:36:55,440 missions that would be integrated and 1016 00:37:00,150 --> 00:36:58,000 coordinated and it was sold as such 1017 00:37:01,670 --> 00:37:00,160 wesley hunter is very important in this 1018 00:37:04,710 --> 00:37:01,680 whole story 1019 00:37:08,310 --> 00:37:04,720 but golden but the deal that was made 1020 00:37:10,630 --> 00:37:08,320 is you omb which they don't like omb 1021 00:37:12,150 --> 00:37:10,640 congress doesn't like these programs 1022 00:37:14,710 --> 00:37:12,160 they'd like to keep them separate they 1023 00:37:16,950 --> 00:37:14,720 have more power that way but if you let 1024 00:37:19,270 --> 00:37:16,960 us have a program it'll be faster better 1025 00:37:21,430 --> 00:37:19,280 cheaper faster better people is the way 1026 00:37:23,589 --> 00:37:21,440 you're selling it it'll cost you less 1027 00:37:25,670 --> 00:37:23,599 over a period of years so it was 1028 00:37:28,150 --> 00:37:25,680 accepted program gets started next 1029 00:37:30,470 --> 00:37:28,160 decision reorientation is in the with 1030 00:37:32,550 --> 00:37:30,480 the moon rock with the mars rock and 1031 00:37:35,270 --> 00:37:32,560 essentially this is the idea of speeding 1032 00:37:37,589 --> 00:37:35,280 up the mars sample return as fast as we 1033 00:37:40,630 --> 00:37:37,599 can faster better cheaper even faster 1034 00:37:41,910 --> 00:37:40,640 better cheaper applied to mars a last 1035 00:37:44,310 --> 00:37:41,920 decision 1036 00:37:47,510 --> 00:37:44,320 problems with faster better cheaper two 1037 00:37:48,950 --> 00:37:47,520 probes go down what are we going to do 1038 00:37:52,230 --> 00:37:48,960 he says to 1039 00:37:53,990 --> 00:37:52,240 his uh nasa is a a i get aaa at that 1040 00:37:57,190 --> 00:37:54,000 point that we got to save the mars 1041 00:37:58,630 --> 00:37:57,200 program he brings in uh mr hubbard from 1042 00:37:59,910 --> 00:37:58,640 california 1043 00:38:01,349 --> 00:37:59,920 and he 1044 00:38:03,510 --> 00:38:01,359 tells give me 1045 00:38:05,030 --> 00:38:03,520 reinvent the program 1046 00:38:07,510 --> 00:38:05,040 give me another program that isn't 1047 00:38:09,589 --> 00:38:07,520 faster better i'll use those words but i 1048 00:38:10,630 --> 00:38:09,599 think it i wanted to be 1049 00:38:11,829 --> 00:38:10,640 more 1050 00:38:14,630 --> 00:38:11,839 realistic 1051 00:38:16,710 --> 00:38:14,640 uh and part and and his last decision 1052 00:38:19,190 --> 00:38:16,720 was essentially spirit and opportunity 1053 00:38:22,230 --> 00:38:19,200 as well i am told by everybody that the 1054 00:38:24,470 --> 00:38:22,240 decision to have two is his decision 1055 00:38:26,310 --> 00:38:24,480 and that goes way against faster better 1056 00:38:29,670 --> 00:38:26,320 cheaper so how are you going to pay for 1057 00:38:32,470 --> 00:38:29,680 it mars is important he taxed other 1058 00:38:34,790 --> 00:38:32,480 divisions of nasa to pay for spirit and 1059 00:38:37,510 --> 00:38:34,800 opportunity and then he goes 1060 00:38:40,470 --> 00:38:37,520 and so you have the next one and he is 1061 00:38:41,829 --> 00:38:40,480 sean o'keefe he i know him well he comes 1062 00:38:44,470 --> 00:38:41,839 from my place 1063 00:38:46,630 --> 00:38:44,480 he is a budget man that's number two in 1064 00:38:48,950 --> 00:38:46,640 the budget he's hired to deal with the 1065 00:38:51,109 --> 00:38:48,960 space station cost overrun 1066 00:38:53,190 --> 00:38:51,119 and then he has to deal with the crisis 1067 00:38:54,950 --> 00:38:53,200 of the columbia going down out of that 1068 00:38:57,270 --> 00:38:54,960 comes the 1069 00:39:01,109 --> 00:38:57,280 moon mars decision of bush ii 1070 00:39:01,910 --> 00:39:01,119 and he as he's and he says 1071 00:39:04,710 --> 00:39:01,920 well 1072 00:39:05,829 --> 00:39:04,720 again mars is a pre is precursory to 1073 00:39:08,550 --> 00:39:05,839 this human 1074 00:39:11,510 --> 00:39:08,560 mission and i am going to enlarge the 1075 00:39:14,069 --> 00:39:11,520 budget of the mars program 1076 00:39:16,790 --> 00:39:14,079 priority uh he comes from omb his view 1077 00:39:18,710 --> 00:39:16,800 of life is you deal it's better to have 1078 00:39:21,190 --> 00:39:18,720 priorities and do something well than do 1079 00:39:23,589 --> 00:39:21,200 a bunch of things not so well and so he 1080 00:39:25,349 --> 00:39:23,599 says i'm going to put money into mars 1081 00:39:27,349 --> 00:39:25,359 but money is going to come from human 1082 00:39:29,270 --> 00:39:27,359 space flight as well as from the science 1083 00:39:31,109 --> 00:39:29,280 division and it's going to grow to the 1084 00:39:31,990 --> 00:39:31,119 billion-dollar class over a period of 1085 00:39:33,589 --> 00:39:32,000 time 1086 00:39:35,109 --> 00:39:33,599 he goes 1087 00:39:37,109 --> 00:39:35,119 o'keefe comes in 1088 00:39:39,670 --> 00:39:37,119 o'keefe deals with the backlash from all 1089 00:39:40,390 --> 00:39:39,680 the other scientists who say why are you 1090 00:39:44,870 --> 00:39:40,400 we 1091 00:39:46,550 --> 00:39:44,880 balance not priority 1092 00:39:48,550 --> 00:39:46,560 so okay so 1093 00:39:50,630 --> 00:39:48,560 i think griffin is so interested in 1094 00:39:52,470 --> 00:39:50,640 constellation he doesn't want to deal 1095 00:39:55,190 --> 00:39:52,480 with uh with the scientific community 1096 00:39:56,790 --> 00:39:55,200 well you can tell about that mr hunters 1097 00:39:58,390 --> 00:39:56,800 but he doesn't want to deal with the 1098 00:40:01,349 --> 00:39:58,400 scientists he wants to deal with 1099 00:40:03,670 --> 00:40:01,359 constellation and he says you science 1100 00:40:05,670 --> 00:40:03,680 administrators you you worry about i'll 1101 00:40:07,589 --> 00:40:05,680 give you money leave me alone i want to 1102 00:40:12,150 --> 00:40:07,599 deal with constellation so basically 1103 00:40:17,109 --> 00:40:14,150 essentially he hires a science 1104 00:40:19,510 --> 00:40:17,119 administrator named stern who's gets him 1105 00:40:20,950 --> 00:40:19,520 in trouble with the scientific community 1106 00:40:23,510 --> 00:40:20,960 and jpl 1107 00:40:26,069 --> 00:40:23,520 alan stern is convinced there's a cabal 1108 00:40:29,190 --> 00:40:26,079 between jpl and the scientific community 1109 00:40:30,710 --> 00:40:29,200 to to to create this monster called mars 1110 00:40:32,710 --> 00:40:30,720 science laboratory which is going to 1111 00:40:34,630 --> 00:40:32,720 cost billions of dollars and he points 1112 00:40:36,390 --> 00:40:34,640 to a national academy of sciences study 1113 00:40:38,390 --> 00:40:36,400 a decadal study that says it's going to 1114 00:40:41,910 --> 00:40:38,400 cost x number of dollars which is far 1115 00:40:44,790 --> 00:40:41,920 fewer so how did it go from a to z 1116 00:40:47,829 --> 00:40:44,800 and obviously you you guys down at jpl 1117 00:40:50,230 --> 00:40:47,839 in the community must be doing something 1118 00:40:52,950 --> 00:40:50,240 wrong and he's going to be tough and 1119 00:40:54,550 --> 00:40:52,960 he's real tough and griffin says i go we 1120 00:40:55,670 --> 00:40:54,560 got to do we got to keep the mars 1121 00:40:57,109 --> 00:40:55,680 science 1122 00:41:00,390 --> 00:40:57,119 laboratory going 1123 00:41:02,870 --> 00:41:00,400 uh get the money to pay for it he he 1124 00:41:04,950 --> 00:41:02,880 looks at spirit and opportunity and he's 1125 00:41:06,550 --> 00:41:04,960 going to cut spirit and opportunity 1126 00:41:08,550 --> 00:41:06,560 he doesn't tell griffin that he's going 1127 00:41:09,990 --> 00:41:08,560 to talk spirit and opportunity there's a 1128 00:41:12,790 --> 00:41:10,000 huge 1129 00:41:14,790 --> 00:41:12,800 backlash from that griffin says 1130 00:41:17,109 --> 00:41:14,800 uh you didn't tell me 1131 00:41:19,750 --> 00:41:17,119 that's too bad bye-bye and that's the 1132 00:41:22,309 --> 00:41:19,760 end of stern and so he brings in another 1133 00:41:23,190 --> 00:41:22,319 brings wiler back weiler is very very 1134 00:41:23,990 --> 00:41:23,200 very 1135 00:41:27,589 --> 00:41:24,000 uh 1136 00:41:30,150 --> 00:41:27,599 canny bureaucratic politician and he put 1137 00:41:32,710 --> 00:41:30,160 and weiler basically is the man behind 1138 00:41:34,950 --> 00:41:32,720 the look looks at the situation 1139 00:41:37,190 --> 00:41:34,960 five minutes looks at the situation and 1140 00:41:39,510 --> 00:41:37,200 says we've got to have a delay 1141 00:41:41,829 --> 00:41:39,520 in this decision now 1142 00:41:44,790 --> 00:41:41,839 mr green said a delay decision is a big 1143 00:41:47,510 --> 00:41:44,800 deal it's a big decision you don't just 1144 00:41:49,349 --> 00:41:47,520 delay a mission two years and relax 1145 00:41:52,630 --> 00:41:49,359 it's a big decision 1146 00:41:55,270 --> 00:41:52,640 stern had gone to griffin to try to get 1147 00:41:56,870 --> 00:41:55,280 a delay in the mars science laboratory 1148 00:41:58,309 --> 00:41:56,880 he was going to delay it and then put a 1149 00:42:00,870 --> 00:41:58,319 cash on it 1150 00:42:03,030 --> 00:42:00,880 to start mars sample return 1151 00:42:04,950 --> 00:42:03,040 via mars science laboratory but he 1152 00:42:06,790 --> 00:42:04,960 needed a delay to do that 1153 00:42:09,589 --> 00:42:06,800 he didn't get his delay from griffin 1154 00:42:12,790 --> 00:42:09,599 weiler gets the delay and if anyone he 1155 00:42:15,109 --> 00:42:12,800 wants a real textbook study of how to do 1156 00:42:17,109 --> 00:42:15,119 things right and how to do things wrong 1157 00:42:19,670 --> 00:42:17,119 in a decision-making process study the 1158 00:42:22,150 --> 00:42:19,680 decision-making process of stern and the 1159 00:42:24,150 --> 00:42:22,160 decision-making process of weiler and 1160 00:42:26,550 --> 00:42:24,160 how they got the boss to give them the 1161 00:42:28,550 --> 00:42:26,560 answer they wanted because wyler got the 1162 00:42:30,630 --> 00:42:28,560 answer he wanted which is the delay the 1163 00:42:33,270 --> 00:42:30,640 decision to delay the decision to delay 1164 00:42:35,910 --> 00:42:33,280 was a very important decision probably 1165 00:42:38,790 --> 00:42:35,920 the most important mars decision 1166 00:42:41,190 --> 00:42:38,800 that griffin that griffin made 1167 00:42:43,430 --> 00:42:41,200 griffin goes 1168 00:42:46,630 --> 00:42:43,440 and so we got another administrator 1169 00:42:48,550 --> 00:42:46,640 and and this is now we have bolden 1170 00:42:50,309 --> 00:42:48,560 now bolden is our present administrator 1171 00:42:51,030 --> 00:42:50,319 and the story is not finished to unfold 1172 00:42:53,990 --> 00:42:51,040 it 1173 00:42:55,990 --> 00:42:54,000 bolden is interesting because 1174 00:42:57,510 --> 00:42:56,000 uh 1175 00:42:58,390 --> 00:42:57,520 essentially he didn't really want the 1176 00:43:00,710 --> 00:42:58,400 job 1177 00:43:02,950 --> 00:43:00,720 uh he said that and he and and they 1178 00:43:06,309 --> 00:43:02,960 didn't want the job because he had had a 1179 00:43:08,390 --> 00:43:06,319 job under golden back in the early 90s 1180 00:43:11,829 --> 00:43:08,400 and had been and found that dealing with 1181 00:43:13,270 --> 00:43:11,839 the politics of the job was dreadful 1182 00:43:14,630 --> 00:43:13,280 couldn't stand it 1183 00:43:16,950 --> 00:43:14,640 and uh 1184 00:43:20,150 --> 00:43:16,960 but he's a good soldier he's a military 1185 00:43:22,790 --> 00:43:20,160 guy and so he said when when obama asked 1186 00:43:25,430 --> 00:43:22,800 him to take the job he couldn't say no 1187 00:43:27,430 --> 00:43:25,440 having taken the job now he has to run 1188 00:43:28,870 --> 00:43:27,440 nasa and he asked for the 1189 00:43:30,870 --> 00:43:28,880 commander-in-chief to give him his 1190 00:43:32,550 --> 00:43:30,880 marching orders but as you know he 1191 00:43:34,870 --> 00:43:32,560 didn't get any marching orders for a 1192 00:43:37,349 --> 00:43:34,880 long while it wasn't until the next year 1193 00:43:39,349 --> 00:43:37,359 2010 that a budget came out and the 1194 00:43:40,790 --> 00:43:39,359 budget said we're going to cancel 1195 00:43:43,910 --> 00:43:40,800 constellation 1196 00:43:45,349 --> 00:43:43,920 now bolden had had very little influence 1197 00:43:47,829 --> 00:43:45,359 in that decision 1198 00:43:50,470 --> 00:43:47,839 and the critical question to be you want 1199 00:43:52,829 --> 00:43:50,480 to ask about a leader is does he have 1200 00:43:55,990 --> 00:43:52,839 influence and does he use it on behalf 1201 00:43:58,630 --> 00:43:56,000 of mars 1202 00:43:59,910 --> 00:43:58,640 that decision that roll out decision was 1203 00:44:02,630 --> 00:43:59,920 dreadful 1204 00:44:04,470 --> 00:44:02,640 uh bolton calls it a disaster it was it 1205 00:44:07,109 --> 00:44:04,480 was a disaster for nasa it was a 1206 00:44:09,510 --> 00:44:07,119 disaster for him personally because he 1207 00:44:11,109 --> 00:44:09,520 hadn't had that much control over it and 1208 00:44:13,109 --> 00:44:11,119 the congress says why should we talk to 1209 00:44:14,870 --> 00:44:13,119 you we should be talking to the omb or 1210 00:44:16,630 --> 00:44:14,880 somebody like that who make really makes 1211 00:44:18,710 --> 00:44:16,640 decisions around here and the 1212 00:44:21,589 --> 00:44:18,720 consequences have hurt his influence 1213 00:44:24,309 --> 00:44:21,599 and so bolden becomes 1214 00:44:26,550 --> 00:44:24,319 caught between this toxic thing that he 1215 00:44:29,109 --> 00:44:26,560 desperately didn't want to be part of 1216 00:44:30,710 --> 00:44:29,119 of washington which is the congress and 1217 00:44:33,190 --> 00:44:30,720 the president fighting 1218 00:44:35,030 --> 00:44:33,200 over a program called constellation 1219 00:44:36,550 --> 00:44:35,040 which has been killed 1220 00:44:38,150 --> 00:44:36,560 uh and then and what are we going to 1221 00:44:40,150 --> 00:44:38,160 replace it with 1222 00:44:41,829 --> 00:44:40,160 and in the end of the day 1223 00:44:44,950 --> 00:44:41,839 finally after months and months and 1224 00:44:47,109 --> 00:44:44,960 months congress makes a decision which 1225 00:44:48,950 --> 00:44:47,119 fortune forces on the president which 1226 00:44:51,589 --> 00:44:48,960 we're going to have a major manned space 1227 00:44:53,510 --> 00:44:51,599 program which the space 1228 00:44:54,710 --> 00:44:53,520 this is called the space 1229 00:44:57,510 --> 00:44:54,720 whatever it is 1230 00:44:59,109 --> 00:44:57,520 it's the rockets big rockets heavy lift 1231 00:45:00,309 --> 00:44:59,119 and we're going to have orion two 1232 00:45:02,390 --> 00:45:00,319 minutes to go 1233 00:45:03,750 --> 00:45:02,400 and uh but they're not going to give you 1234 00:45:04,630 --> 00:45:03,760 more money 1235 00:45:05,910 --> 00:45:04,640 so 1236 00:45:07,430 --> 00:45:05,920 all of a sudden 1237 00:45:09,430 --> 00:45:07,440 you've got a situation of being an 1238 00:45:12,150 --> 00:45:09,440 administrator in which you've got this 1239 00:45:13,349 --> 00:45:12,160 massive new man program 1240 00:45:15,349 --> 00:45:13,359 you've got 1241 00:45:17,030 --> 00:45:15,359 the mars program which you are very 1242 00:45:18,950 --> 00:45:17,040 supportive of and i'll get back to in a 1243 00:45:20,630 --> 00:45:18,960 minute because essentially while all 1244 00:45:23,430 --> 00:45:20,640 this is going on 1245 00:45:25,190 --> 00:45:23,440 this big politics stuff is going on 1246 00:45:27,750 --> 00:45:25,200 what is going on at the 1247 00:45:30,309 --> 00:45:27,760 science level wilder level 1248 00:45:32,790 --> 00:45:30,319 is a negotiation between wyler and his 1249 00:45:34,710 --> 00:45:32,800 counterpart in england to have 1250 00:45:38,069 --> 00:45:34,720 mars sample return 1251 00:45:40,550 --> 00:45:38,079 via this exomars effort with europe so 1252 00:45:42,870 --> 00:45:40,560 this is going on at that level but this 1253 00:45:45,829 --> 00:45:42,880 other stuff is going on at another level 1254 00:45:48,230 --> 00:45:45,839 which is all about manned space and all 1255 00:45:49,270 --> 00:45:48,240 about money and finally they come 1256 00:45:51,510 --> 00:45:49,280 together 1257 00:45:52,710 --> 00:45:51,520 when you're dealing with the budget 1258 00:45:54,870 --> 00:45:52,720 last 1259 00:45:56,230 --> 00:45:54,880 between thanksgiving and christmas of 1260 00:45:57,510 --> 00:45:56,240 last year 1261 00:46:00,069 --> 00:45:57,520 when you're dealing with the final 1262 00:46:03,750 --> 00:46:00,079 budget decisions nasa has people in 1263 00:46:04,710 --> 00:46:03,760 paris negotiating with europe over exo 1264 00:46:06,630 --> 00:46:04,720 mars 1265 00:46:09,030 --> 00:46:06,640 bolden is talking to dordane his 1266 00:46:10,470 --> 00:46:09,040 counterpart over there about 1267 00:46:12,230 --> 00:46:10,480 whether or not we can really go ahead 1268 00:46:14,470 --> 00:46:12,240 with this this is three years of 1269 00:46:16,069 --> 00:46:14,480 negotiation that's been going on at the 1270 00:46:17,990 --> 00:46:16,079 same time he's talking to the budget 1271 00:46:20,870 --> 00:46:18,000 bureau the office of management budget 1272 00:46:23,030 --> 00:46:20,880 and the baffling budget says look look 1273 00:46:25,349 --> 00:46:23,040 you've got no money 1274 00:46:27,430 --> 00:46:25,359 for james webb space telescope it's gone 1275 00:46:29,510 --> 00:46:27,440 up to 8.7 billion dollars where are you 1276 00:46:31,990 --> 00:46:29,520 going to get the money for that he says 1277 00:46:32,950 --> 00:46:32,000 they say to him make a decision 1278 00:46:35,349 --> 00:46:32,960 web 1279 00:46:37,589 --> 00:46:35,359 versus mars what do you want you can't 1280 00:46:39,430 --> 00:46:37,599 have two huge 1281 00:46:41,190 --> 00:46:39,440 flagship programs 1282 00:46:43,349 --> 00:46:41,200 it's not the decision 1283 00:46:45,349 --> 00:46:43,359 and so bolden says 1284 00:46:47,430 --> 00:46:45,359 well truth of the matter is bolden makes 1285 00:46:50,230 --> 00:46:47,440 a decision but it's not his decision 1286 00:46:51,910 --> 00:46:50,240 it's forced on him by the omb and is 1287 00:46:53,750 --> 00:46:51,920 forced on the omb 1288 00:46:56,069 --> 00:46:53,760 by the political people who have already 1289 00:46:57,349 --> 00:46:56,079 decided that james webb will survive one 1290 00:46:58,870 --> 00:46:57,359 way or another 1291 00:46:59,750 --> 00:46:58,880 and we'll take the money from somewhere 1292 00:47:00,630 --> 00:46:59,760 else 1293 00:47:02,069 --> 00:47:00,640 so 1294 00:47:04,230 --> 00:47:02,079 what's the 1295 00:47:07,270 --> 00:47:04,240 what is the moral of the story 1296 00:47:08,870 --> 00:47:07,280 the moral of the story is that all that 1297 00:47:11,510 --> 00:47:08,880 if you're asking the question do nasa 1298 00:47:13,670 --> 00:47:11,520 administrators matter yeah they matter 1299 00:47:15,510 --> 00:47:13,680 do they have influence not all of them 1300 00:47:36,950 --> 00:47:15,520 that and if they have influence they use 1301 00:47:40,069 --> 00:47:38,710 goes from nasa ames excuse me my 1302 00:47:42,150 --> 00:47:40,079 question is whether um a nasa 1303 00:47:43,829 --> 00:47:42,160 administrator will ever be able to 1304 00:47:46,390 --> 00:47:43,839 uh set a rational 1305 00:47:47,910 --> 00:47:46,400 um strategic direction uh for the agency 1306 00:47:49,349 --> 00:47:47,920 um should we be looking at another type 1307 00:47:50,870 --> 00:47:49,359 of organization to do that like a 1308 00:47:52,390 --> 00:47:50,880 committee and i've been thinking about 1309 00:47:54,630 --> 00:47:52,400 that since this morning when duane day 1310 00:47:56,230 --> 00:47:54,640 was talking about the ssb um and how 1311 00:47:58,470 --> 00:47:56,240 that absorbs some of the functions of 1312 00:47:59,990 --> 00:47:58,480 the naca jim green is saying that the 1313 00:48:01,990 --> 00:48:00,000 decadal surveys work very well in 1314 00:48:03,430 --> 00:48:02,000 setting a strategic direction and giving 1315 00:48:05,829 --> 00:48:03,440 everything that an administrator has to 1316 00:48:07,109 --> 00:48:05,839 balance uh should strategic direction be 1317 00:48:08,790 --> 00:48:07,119 coming from a different area that he 1318 00:48:10,069 --> 00:48:08,800 could then implement 1319 00:48:14,710 --> 00:48:10,079 i think the 1320 00:48:18,790 --> 00:48:17,430 the problem any any administrator has 1321 00:48:21,349 --> 00:48:18,800 dealing with his 1322 00:48:23,589 --> 00:48:21,359 the issue of a rational program 1323 00:48:25,430 --> 00:48:23,599 is that any administrator 1324 00:48:26,230 --> 00:48:25,440 isn't around that long 1325 00:48:28,790 --> 00:48:26,240 uh 1326 00:48:30,790 --> 00:48:28,800 note the typical administrators around 1327 00:48:32,950 --> 00:48:30,800 four years maybe five years golden was 1328 00:48:34,390 --> 00:48:32,960 the exception being nine and a half 1329 00:48:35,190 --> 00:48:34,400 that's rare 1330 00:48:35,990 --> 00:48:35,200 uh 1331 00:48:36,710 --> 00:48:36,000 so 1332 00:48:37,510 --> 00:48:36,720 the 1333 00:48:39,990 --> 00:48:37,520 what 1334 00:48:42,630 --> 00:48:40,000 the best you can do 1335 00:48:45,349 --> 00:48:42,640 is is to have the community 1336 00:48:46,790 --> 00:48:45,359 come up with a rational program have the 1337 00:48:50,309 --> 00:48:46,800 program office 1338 00:48:53,430 --> 00:48:50,319 the people who are career civil servants 1339 00:48:55,829 --> 00:48:53,440 buy in to that rational program 1340 00:48:59,829 --> 00:48:55,839 and then you try to you try to make sure 1341 00:49:02,069 --> 00:48:59,839 the administrator is on your side 1342 00:49:03,910 --> 00:49:02,079 and that he's good enough to sell it to 1343 00:49:04,950 --> 00:49:03,920 the political community 1344 00:49:07,190 --> 00:49:04,960 the 1345 00:49:08,870 --> 00:49:07,200 essentially mars exploration is like a 1346 00:49:12,069 --> 00:49:08,880 marathon race 1347 00:49:14,710 --> 00:49:12,079 it's going on over a year decades really 1348 00:49:17,270 --> 00:49:14,720 and so and the administrator comes in 1349 00:49:19,510 --> 00:49:17,280 and vectors into that off and on 1350 00:49:22,230 --> 00:49:19,520 so the more you can have a you won't get 1351 00:49:26,150 --> 00:49:22,240 ever you'll never get rationality 1352 00:49:27,750 --> 00:49:26,160 you get what is called muddling through 1353 00:49:28,950 --> 00:49:27,760 muddling through and that's the best 1354 00:49:30,069 --> 00:49:28,960 you're going to do 1355 00:49:40,230 --> 00:49:30,079 bundling through is the best you're 1356 00:49:40,240 --> 00:49:55,030 take about five minutes 1357 00:49:58,309 --> 00:49:56,630 thanks we've had a variety of fantastic 1358 00:50:03,190 --> 00:49:58,319 perspectives of mars exploration let's 1359 00:50:07,910 --> 00:50:05,190 hi i'm hiding behind the column here 1360 00:50:11,510 --> 00:50:07,920 richard burke i'm jim burke's son 1361 00:50:17,030 --> 00:50:14,630 several speakers have alluded to 1362 00:50:19,270 --> 00:50:17,040 water liquid water being the gold 1363 00:50:21,910 --> 00:50:19,280 standard for habitability 1364 00:50:24,710 --> 00:50:21,920 wondering about organisms in antarctica 1365 00:50:25,510 --> 00:50:24,720 that have no liquid water and if there's 1366 00:50:27,589 --> 00:50:25,520 any 1367 00:50:32,230 --> 00:50:27,599 addition to this discussion 1368 00:50:36,790 --> 00:50:35,510 well uh it's a great question um 1369 00:50:38,470 --> 00:50:36,800 one of the things 1370 00:50:39,990 --> 00:50:38,480 that the 1371 00:50:42,150 --> 00:50:40,000 extremophile 1372 00:50:42,870 --> 00:50:42,160 revolution if we can call it that or the 1373 00:50:48,470 --> 00:50:42,880 the 1374 00:50:51,430 --> 00:50:48,480 of discoveries of of ever 1375 00:50:52,630 --> 00:50:51,440 increasing extreme conditions that 1376 00:50:55,750 --> 00:50:52,640 that uh 1377 00:50:58,790 --> 00:50:55,760 that life can inhabit on earth 1378 00:51:01,750 --> 00:50:58,800 what they all do have in common is 1379 00:51:04,710 --> 00:51:01,760 their utilization of liquid water but 1380 00:51:06,630 --> 00:51:04,720 what's remarkable and you've alluded to 1381 00:51:11,510 --> 00:51:06,640 this uh in in the situation of 1382 00:51:14,950 --> 00:51:12,950 they 1383 00:51:17,030 --> 00:51:14,960 life has the ability to really push that 1384 00:51:20,230 --> 00:51:17,040 boundary so 1385 00:51:21,430 --> 00:51:20,240 so even in situations where 1386 00:51:23,349 --> 00:51:21,440 where it's 1387 00:51:26,309 --> 00:51:23,359 it's only sort of true there's liquid 1388 00:51:28,069 --> 00:51:26,319 water and uh you know the these uh 1389 00:51:30,630 --> 00:51:28,079 crypto endolythic organisms that are 1390 00:51:34,150 --> 00:51:30,640 living inside of frozen rocks in 1391 00:51:36,150 --> 00:51:34,160 antarctica but somehow using um sunlight 1392 00:51:39,349 --> 00:51:36,160 in the top layers of those rocks to 1393 00:51:41,190 --> 00:51:39,359 slightly warm themselves above the um 1394 00:51:43,670 --> 00:51:41,200 the uh 1395 00:51:44,790 --> 00:51:43,680 freezing point or places where they're 1396 00:51:47,990 --> 00:51:44,800 using 1397 00:51:51,589 --> 00:51:48,000 the salinity to push down below what 1398 00:51:53,910 --> 00:51:51,599 would seem to be the uh the 1399 00:51:56,230 --> 00:51:53,920 cold limit but they're using various 1400 00:51:57,910 --> 00:51:56,240 natural antifreezes so i don't think 1401 00:51:59,589 --> 00:51:57,920 it's literally true 1402 00:52:01,829 --> 00:51:59,599 that we've found 1403 00:52:05,270 --> 00:52:01,839 life that does not use liquid water but 1404 00:52:06,230 --> 00:52:05,280 it is remarkable the extent to which um 1405 00:52:07,990 --> 00:52:06,240 you know 1406 00:52:10,549 --> 00:52:08,000 the the literal interpretation of what 1407 00:52:15,349 --> 00:52:10,559 we need what we mean by liquid both on 1408 00:52:17,589 --> 00:52:15,359 the cold and hot and saline and acidic 1409 00:52:19,750 --> 00:52:17,599 boundaries have been pushed by life and 1410 00:52:21,430 --> 00:52:19,760 it really shows us as as i said before 1411 00:52:23,349 --> 00:52:21,440 that life seems to be not just necessary 1412 00:52:25,910 --> 00:52:23,359 but almost the water seems to be not 1413 00:52:28,470 --> 00:52:25,920 just necessary but almost sufficient for 1414 00:52:30,549 --> 00:52:28,480 uh for life so those those examples kind 1415 00:52:32,950 --> 00:52:30,559 of contribute to that sense that at 1416 00:52:35,270 --> 00:52:32,960 least for our kind of life that liquid 1417 00:52:37,589 --> 00:52:35,280 water in you know in in all its 1418 00:52:39,990 --> 00:52:37,599 manifestations even if it's just you 1419 00:52:41,910 --> 00:52:40,000 know the on the grains between minerals 1420 00:52:44,549 --> 00:52:41,920 and otherwise pretty dry and pretty 1421 00:52:46,790 --> 00:52:44,559 frozen rock is really the the key 1422 00:52:48,630 --> 00:52:46,800 criterion thank you 1423 00:52:52,549 --> 00:52:48,640 any further questions oh sorry answers 1424 00:52:56,710 --> 00:52:54,870 i think so this really matters for mars 1425 00:52:59,510 --> 00:52:56,720 because of the temperature environment 1426 00:53:01,109 --> 00:52:59,520 of the planet that just how close and 1427 00:53:03,270 --> 00:53:01,119 where you might be in terms of getting 1428 00:53:05,430 --> 00:53:03,280 liquid and if you get it 1429 00:53:07,990 --> 00:53:05,440 liquid by making it a brine then you 1430 00:53:10,309 --> 00:53:08,000 have other issues with biology the water 1431 00:53:12,150 --> 00:53:10,319 activity is really what counts 1432 00:53:14,390 --> 00:53:12,160 so it's an important point 1433 00:53:16,790 --> 00:53:14,400 i'd like to take just a moment to 1434 00:53:18,950 --> 00:53:16,800 further answer a question that was asked 1435 00:53:20,870 --> 00:53:18,960 about why aren't the meteorites 1436 00:53:23,109 --> 00:53:20,880 the samples of choice 1437 00:53:25,670 --> 00:53:23,119 one reason is is because 1438 00:53:27,109 --> 00:53:25,680 you won't get a sample of a sedimentary 1439 00:53:29,589 --> 00:53:27,119 rock back 1440 00:53:31,589 --> 00:53:29,599 via a meteorite it's just not going to 1441 00:53:33,510 --> 00:53:31,599 happen and yet those are the very kinds 1442 00:53:36,950 --> 00:53:33,520 of materials that could really preserve 1443 00:53:38,309 --> 00:53:36,960 biosignatures of that past line so it's 1444 00:53:40,069 --> 00:53:38,319 not just a matter of we don't know where 1445 00:53:41,910 --> 00:53:40,079 the rocks came from it's also a matter 1446 00:53:43,510 --> 00:53:41,920 if we want the right rock and that's 1447 00:53:45,990 --> 00:53:43,520 what we've really been trying to look 1448 00:53:46,000 --> 00:53:57,990 other questions 1449 00:54:00,950 --> 00:53:58,710 so 1450 00:54:03,190 --> 00:54:00,960 one of the issues that the mars program 1451 00:54:04,710 --> 00:54:03,200 has been dealing with of late is 1452 00:54:06,150 --> 00:54:04,720 competition 1453 00:54:08,069 --> 00:54:06,160 the decadal survey 1454 00:54:10,390 --> 00:54:08,079 obviously recommended the mars sample 1455 00:54:11,349 --> 00:54:10,400 return as the primary flagship mission 1456 00:54:13,190 --> 00:54:11,359 but the 1457 00:54:14,950 --> 00:54:13,200 europa mission was certainly highly 1458 00:54:17,750 --> 00:54:14,960 considered as well and i think there was 1459 00:54:18,790 --> 00:54:17,760 a uranus mission as well um 1460 00:54:21,510 --> 00:54:18,800 what 1461 00:54:23,109 --> 00:54:21,520 do you see as the technical scientific 1462 00:54:26,630 --> 00:54:23,119 or political 1463 00:54:29,109 --> 00:54:26,640 validities of a mars mission 1464 00:54:30,630 --> 00:54:29,119 as as opposed to the other missions why 1465 00:54:36,309 --> 00:54:30,640 do you think that mars should be first 1466 00:54:42,069 --> 00:54:38,710 what you're asking to sit at mars 1467 00:54:47,190 --> 00:54:44,870 i i truly believe that the issue between 1468 00:54:48,710 --> 00:54:47,200 say mars and europa it's not really a 1469 00:54:50,950 --> 00:54:48,720 question about which of those goats the 1470 00:54:52,950 --> 00:54:50,960 decadal survey was pretty clear that you 1471 00:54:54,870 --> 00:54:52,960 know give this a try if you can't work 1472 00:54:57,589 --> 00:54:54,880 this out this is next 1473 00:55:00,710 --> 00:54:57,599 our problem right now is we can't do any 1474 00:55:02,630 --> 00:55:00,720 flagship class activity with the budgets 1475 00:55:06,390 --> 00:55:02,640 that we've got going forward 1476 00:55:08,069 --> 00:55:06,400 so i i think that's the the real issue 1477 00:55:14,789 --> 00:55:08,079 solve that one and then we can get back 1478 00:55:18,870 --> 00:55:16,870 yes thank you um john sarkis from the 1479 00:55:22,069 --> 00:55:18,880 csiro in australia 1480 00:55:26,069 --> 00:55:22,079 um just in regards to sample return 1481 00:55:28,230 --> 00:55:26,079 everyone agrees it's a desirable 1482 00:55:30,150 --> 00:55:28,240 mission and so on however as i said 1483 00:55:32,870 --> 00:55:30,160 there are potentially 1484 00:55:34,710 --> 00:55:32,880 very large risks involved in that 1485 00:55:37,030 --> 00:55:34,720 so for example 1486 00:55:38,309 --> 00:55:37,040 if the sample contains some microbial 1487 00:55:40,470 --> 00:55:38,319 life or 1488 00:55:43,270 --> 00:55:40,480 or so on then returning that to the 1489 00:55:44,710 --> 00:55:43,280 earth could be potentially catastrophic 1490 00:55:46,150 --> 00:55:44,720 because there is there would be no 1491 00:55:49,109 --> 00:55:46,160 immunity to it 1492 00:55:52,069 --> 00:55:49,119 but also if we do send people to 1493 00:55:54,309 --> 00:55:52,079 to um to mars in the future then we'll 1494 00:55:56,069 --> 00:55:54,319 immediately contaminate the place 1495 00:55:59,109 --> 00:55:56,079 um and therefore 1496 00:56:01,030 --> 00:55:59,119 um you know we'll never be quite sure if 1497 00:56:03,750 --> 00:56:01,040 we do discover life subsequent 1498 00:56:05,030 --> 00:56:03,760 subsequently um is it indigenous or was 1499 00:56:06,309 --> 00:56:05,040 it introduced 1500 00:56:08,789 --> 00:56:06,319 um 1501 00:56:10,870 --> 00:56:08,799 and and so i'd like to hear your your 1502 00:56:12,789 --> 00:56:10,880 opinions on that you know about how we 1503 00:56:15,829 --> 00:56:12,799 could get around those two 1504 00:56:17,589 --> 00:56:15,839 two problems um and be confident that if 1505 00:56:19,430 --> 00:56:17,599 there is life we're safe 1506 00:56:21,990 --> 00:56:19,440 from it and also you know that we're 1507 00:56:25,510 --> 00:56:22,000 confident that it is indigenous to mars 1508 00:56:30,630 --> 00:56:28,390 well of course uh nasa has a planetary 1509 00:56:33,270 --> 00:56:30,640 protection program which 1510 00:56:34,470 --> 00:56:33,280 specifically uh is 1511 00:56:35,670 --> 00:56:34,480 exists 1512 00:56:36,630 --> 00:56:35,680 to 1513 00:56:39,349 --> 00:56:36,640 address 1514 00:56:40,789 --> 00:56:39,359 those questions 1515 00:56:42,390 --> 00:56:40,799 we don't know 1516 00:56:43,589 --> 00:56:42,400 complete we don't we don't have a 1517 00:56:45,109 --> 00:56:43,599 completely clear 1518 00:56:47,670 --> 00:56:45,119 answer to how 1519 00:56:53,270 --> 00:56:47,680 serious those those concerns are my own 1520 00:56:58,710 --> 00:56:55,589 likely to be infected by martian 1521 00:57:00,630 --> 00:56:58,720 organisms even if they do exist because 1522 00:57:01,430 --> 00:57:00,640 if you look at earth 1523 00:57:03,349 --> 00:57:01,440 the 1524 00:57:05,910 --> 00:57:03,359 evolution of 1525 00:57:10,309 --> 00:57:05,920 um of parasites and 1526 00:57:12,230 --> 00:57:10,319 of um dangerous microbes and their host 1527 00:57:13,670 --> 00:57:12,240 and target organisms very closely 1528 00:57:16,150 --> 00:57:13,680 coupled together 1529 00:57:18,789 --> 00:57:16,160 um and so it's it's 1530 00:57:21,109 --> 00:57:18,799 i think less likely that we would suffer 1531 00:57:23,190 --> 00:57:21,119 and an infestation by some kind of 1532 00:57:25,270 --> 00:57:23,200 organism that had really had a separate 1533 00:57:28,390 --> 00:57:25,280 evolution but of course we don't know 1534 00:57:30,789 --> 00:57:28,400 that and because of the existential 1535 00:57:32,549 --> 00:57:30,799 risks involved in being wrong the 1536 00:57:35,190 --> 00:57:32,559 responsible thing to do is to have a 1537 00:57:37,589 --> 00:57:35,200 planetary protection program and in my 1538 00:57:39,109 --> 00:57:37,599 view we have an adequate program to 1539 00:57:41,190 --> 00:57:39,119 guard against that but you know it's 1540 00:57:42,630 --> 00:57:41,200 it's it's worth asking and we uh we 1541 00:57:45,190 --> 00:57:42,640 continually um 1542 00:57:46,710 --> 00:57:45,200 we review that that question and we 1543 00:57:56,150 --> 00:57:46,720 ought to keep doing it as we learn more 1544 00:58:00,069 --> 00:57:57,910 i i actually wanted to offer an 1545 00:58:02,789 --> 00:58:00,079 observation which uh sparked by the 1546 00:58:04,789 --> 00:58:02,799 question of mars versus europa 1547 00:58:07,030 --> 00:58:04,799 and and it's it's a it's a personal 1548 00:58:09,829 --> 00:58:07,040 observation over the past few weeks 1549 00:58:12,390 --> 00:58:09,839 i've set in on briefings on two major 1550 00:58:14,710 --> 00:58:12,400 studies that nasa initiated in response 1551 00:58:16,470 --> 00:58:14,720 to the proposed budget cuts orlando 1552 00:58:19,190 --> 00:58:16,480 figueroa led a group called the mars 1553 00:58:21,510 --> 00:58:19,200 program planning group mppg 1554 00:58:24,069 --> 00:58:21,520 and the europa folks their science 1555 00:58:25,750 --> 00:58:24,079 definition team uh under jim green's 1556 00:58:28,230 --> 00:58:25,760 direction went back and did a major 1557 00:58:31,510 --> 00:58:28,240 study and both of those groups bit the 1558 00:58:33,430 --> 00:58:31,520 bullet and they completely rescued the 1559 00:58:35,349 --> 00:58:33,440 missions that had been part of the 1560 00:58:38,230 --> 00:58:35,359 decadal survey 1561 00:58:40,069 --> 00:58:38,240 while and and maintain a substantial 1562 00:58:42,309 --> 00:58:40,079 amount of the science that both of them 1563 00:58:44,470 --> 00:58:42,319 had in the decadal survey which makes 1564 00:58:46,710 --> 00:58:44,480 them still high priority and yet they've 1565 00:58:49,270 --> 00:58:46,720 managed to reduce the cost by a factor 1566 00:58:51,030 --> 00:58:49,280 of two or more and the cost has been 1567 00:58:53,270 --> 00:58:51,040 validated by an independent group of 1568 00:58:55,190 --> 00:58:53,280 people the same group that did the uh 1569 00:58:57,670 --> 00:58:55,200 the validation of the decadal survey 1570 00:59:01,750 --> 00:58:57,680 missions to begin with the irony to me 1571 00:59:03,349 --> 00:59:01,760 is that if the budget were still at 1.5 1572 00:59:04,710 --> 00:59:03,359 it wouldn't be either or we could do 1573 00:59:07,510 --> 00:59:04,720 them both 1574 00:59:09,750 --> 00:59:07,520 we could be standing on the you know on 1575 00:59:11,829 --> 00:59:09,760 the on the threshold of a phenomenal era 1576 00:59:13,750 --> 00:59:11,839 where we can actually explore this 1577 00:59:19,670 --> 00:59:13,760 question of habitability on two fronts 1578 00:59:24,710 --> 00:59:21,829 well we had the benefits over this last 1579 00:59:27,510 --> 00:59:24,720 decade of both a very vigorous outer 1580 00:59:28,789 --> 00:59:27,520 planets program and a very vigorous mars 1581 00:59:30,069 --> 00:59:28,799 program 1582 00:59:33,030 --> 00:59:30,079 and 1583 00:59:34,789 --> 00:59:33,040 to argue scientifically that you know we 1584 00:59:36,069 --> 00:59:34,799 should have just had one it's certainly 1585 00:59:38,230 --> 00:59:36,079 hard to do that given all the 1586 00:59:40,549 --> 00:59:38,240 discoveries in both those areas 1587 00:59:42,710 --> 00:59:40,559 but just to finish the the point about 1588 00:59:44,470 --> 00:59:42,720 sample return if you have a sample 1589 00:59:47,030 --> 00:59:44,480 return is one way of knowing what the 1590 00:59:49,190 --> 00:59:47,040 environment is before the humans step 1591 00:59:50,549 --> 00:59:49,200 down on it and whether or not there are 1592 00:59:52,549 --> 00:59:50,559 certain dangers that they might 1593 00:59:54,309 --> 00:59:52,559 encounter in that environment 1594 00:59:55,750 --> 00:59:54,319 and planetary protection is the thing 1595 00:59:56,789 --> 00:59:55,760 that's going to keep us safe in the 1596 01:00:01,670 --> 00:59:56,799 meantime 1597 01:00:04,870 --> 01:00:03,750 all right thank you very much and let's 1598 01:00:08,870 --> 01:00:04,880 take a minute to thank all of our
