--> 00:00:38,559 and welcome to ask an astrobiologist a 5 00:00:42,950 --> 00:00:40,800 show that celebrates the science and 6 00:00:44,549 --> 00:00:42,960 celebrates the scientists involved in 7 00:00:45,510 --> 00:00:44,559 our quest to understand the nature of 8 00:00:47,910 --> 00:00:45,520 life 9 00:00:49,750 --> 00:00:47,920 i'm your host dr graham wow and we're 10 00:00:52,150 --> 00:00:49,760 brought to you by the nasa astrobiology 11 00:00:53,750 --> 00:00:52,160 program and saginet.org 12 00:00:56,069 --> 00:00:53,760 as always we want to give a huge shout 13 00:00:57,990 --> 00:00:56,079 out to those out there who share about 14 00:01:00,069 --> 00:00:58,000 our show and interact with our guests 15 00:01:01,670 --> 00:01:00,079 and talk about astrobiology with us on 16 00:01:02,790 --> 00:01:01,680 twitter and all the other places you can 17 00:01:04,549 --> 00:01:02,800 find us 18 00:01:07,030 --> 00:01:04,559 this month we want to highlight garrett 19 00:01:09,190 --> 00:01:07,040 champion for sharing on twitter about 20 00:01:10,789 --> 00:01:09,200 today's episode though later on in the 21 00:01:12,710 --> 00:01:10,799 show we'll also talk about many of you 22 00:01:14,550 --> 00:01:12,720 who've been sharing and talking about 23 00:01:16,789 --> 00:01:14,560 technology and instruments in 24 00:01:19,190 --> 00:01:16,799 astrobiology and that's exactly what 25 00:01:20,950 --> 00:01:19,200 today's episode is is going to focus on 26 00:01:23,749 --> 00:01:20,960 we have two researchers from nasa 27 00:01:25,590 --> 00:01:23,759 joining us who've both been involved in 28 00:01:27,990 --> 00:01:25,600 the technology and the science of 29 00:01:30,469 --> 00:01:28,000 astrobiology and how we look for life 30 00:01:32,710 --> 00:01:30,479 out there just this past week the nasa 31 00:01:34,630 --> 00:01:32,720 astrobiology program 32 00:01:38,149 --> 00:01:34,640 and the enfold or network for life 33 00:01:40,950 --> 00:01:38,159 detection rcn together put on a workshop 34 00:01:43,830 --> 00:01:40,960 called the future of the search for life 35 00:01:46,389 --> 00:01:43,840 or fossil bringing together researchers 36 00:01:48,230 --> 00:01:46,399 and technologists involved in the 37 00:01:50,710 --> 00:01:48,240 synergies and the intersections of how 38 00:01:53,030 --> 00:01:50,720 we develop instruments and technology 39 00:01:55,270 --> 00:01:53,040 for conducting life detection science 40 00:01:57,670 --> 00:01:55,280 and both of today's guests were involved 41 00:01:59,830 --> 00:01:57,680 in the committee organizing this exact 42 00:02:01,590 --> 00:01:59,840 meeting so without further ado i'd like 43 00:02:03,510 --> 00:02:01,600 to bring both of them on i'll introduce 44 00:02:05,670 --> 00:02:03,520 both first and then we can say hello 45 00:02:08,150 --> 00:02:05,680 uh dr stephanie getty is the acting 46 00:02:10,070 --> 00:02:08,160 director of the solar system exploration 47 00:02:12,309 --> 00:02:10,080 division and a planetary research 48 00:02:14,630 --> 00:02:12,319 scientist at nasa's goddard space flight 49 00:02:17,670 --> 00:02:14,640 center her research interests are in the 50 00:02:19,350 --> 00:02:17,680 area of in-situ planetary exploration 51 00:02:21,830 --> 00:02:19,360 particularly in the pursuit of 52 00:02:23,350 --> 00:02:21,840 understanding the origin and evolution 53 00:02:25,750 --> 00:02:23,360 of past and present habitable 54 00:02:27,030 --> 00:02:25,760 environments in our solar system she is 55 00:02:28,790 --> 00:02:27,040 currently the deputy principal 56 00:02:30,470 --> 00:02:28,800 investigator as well of the da vinci 57 00:02:32,070 --> 00:02:30,480 mission to venus 58 00:02:34,229 --> 00:02:32,080 and then we also have joining us dr 59 00:02:36,309 --> 00:02:34,239 richard quinn he's a research scientist 60 00:02:38,309 --> 00:02:36,319 at nasa's ames research center he's been 61 00:02:40,070 --> 00:02:38,319 involved in a variety of projects 62 00:02:42,070 --> 00:02:40,080 involving instrument and technology 63 00:02:44,309 --> 00:02:42,080 development for earth and space 64 00:02:46,949 --> 00:02:44,319 exploration including research in the 65 00:02:49,910 --> 00:02:46,959 atacama desert on instrumentation for 66 00:02:51,830 --> 00:02:49,920 mars exploration and technologies for 67 00:02:53,670 --> 00:02:51,840 exploring the icy worlds of our solar 68 00:02:55,589 --> 00:02:53,680 system he's also a member of the 69 00:02:58,229 --> 00:02:55,599 steering committee for the rcn called 70 00:02:59,830 --> 00:02:58,239 the network for ocean worlds or now uh 71 00:03:00,949 --> 00:02:59,840 so doctors getty and quinn thank you 72 00:03:03,190 --> 00:03:00,959 both for joining us for ask an 73 00:03:05,509 --> 00:03:03,200 astrobiologist 74 00:03:07,030 --> 00:03:05,519 uh you're welcome glad to be here 75 00:03:09,190 --> 00:03:07,040 glad to be here graham thanks for the 76 00:03:11,430 --> 00:03:09,200 invitation yeah this is super exciting 77 00:03:13,509 --> 00:03:11,440 to have you on uh i wanted to talk about 78 00:03:15,509 --> 00:03:13,519 the builder show for some time now but 79 00:03:17,670 --> 00:03:15,519 our main impetus was to talk primarily 80 00:03:19,030 --> 00:03:17,680 to start off with this workshop that 81 00:03:21,030 --> 00:03:19,040 we've convened 82 00:03:23,030 --> 00:03:21,040 after biology 83 00:03:24,789 --> 00:03:23,040 and so i'm wondering um 84 00:03:27,670 --> 00:03:24,799 stephanie you don't mind what were the 85 00:03:29,350 --> 00:03:27,680 motivations for the fossil workshop uh 86 00:03:31,190 --> 00:03:29,360 and what was really the need to have 87 00:03:34,229 --> 00:03:31,200 this workshop 88 00:03:35,910 --> 00:03:34,239 well that is um an appreciated question 89 00:03:37,990 --> 00:03:35,920 and i hope that richard gets a chance to 90 00:03:39,830 --> 00:03:38,000 respond to because he's been so central 91 00:03:40,949 --> 00:03:39,840 to the organization of this workshop but 92 00:03:42,390 --> 00:03:40,959 of course 93 00:03:44,869 --> 00:03:42,400 you know life detection is one of those 94 00:03:46,550 --> 00:03:44,879 profound um 95 00:03:48,550 --> 00:03:46,560 opportunities that we have now that 96 00:03:50,710 --> 00:03:48,560 we're learning more about habitable 97 00:03:53,030 --> 00:03:50,720 environments throughout our solar system 98 00:03:55,589 --> 00:03:53,040 and beyond right but this workshop 99 00:03:57,509 --> 00:03:55,599 really focuses on the concept of being 100 00:04:00,789 --> 00:03:57,519 able to go and visit a habitable 101 00:04:04,630 --> 00:04:00,799 environment and how would we confidently 102 00:04:06,470 --> 00:04:04,640 um detect life uh uh you know answers we 103 00:04:09,350 --> 00:04:06,480 have questions about 104 00:04:11,509 --> 00:04:09,360 uh the development of life in some of 105 00:04:14,550 --> 00:04:11,519 these 106 00:04:18,150 --> 00:04:14,560 solar system so we don't 107 00:04:19,749 --> 00:04:18,160 uh fully know how uh how to to do that 108 00:04:21,990 --> 00:04:19,759 in a comprehensive way and for all 109 00:04:24,070 --> 00:04:22,000 environments and so we're holding this 110 00:04:25,909 --> 00:04:24,080 workshop to really engage 111 00:04:27,749 --> 00:04:25,919 um the communities that are gonna be 112 00:04:29,670 --> 00:04:27,759 thankful to answering this question from 113 00:04:32,870 --> 00:04:29,680 the science community 114 00:04:35,430 --> 00:04:32,880 really broadly engaging 115 00:04:36,390 --> 00:04:35,440 not only seasoned planetary scientists 116 00:04:39,430 --> 00:04:36,400 but also 117 00:04:41,430 --> 00:04:39,440 new minds uh in the pursuit of this this 118 00:04:43,350 --> 00:04:41,440 question but also we also need 119 00:04:45,350 --> 00:04:43,360 technologists and we need engineers to 120 00:04:47,909 --> 00:04:45,360 realize those goals so this workshop is 121 00:04:50,390 --> 00:04:47,919 really um you know has the objective of 122 00:04:53,189 --> 00:04:50,400 bringing together those communities and 123 00:04:55,670 --> 00:04:53,199 uh and taking a systematic um a 124 00:04:58,550 --> 00:04:55,680 combination of systematic and kind of 125 00:05:00,870 --> 00:04:58,560 creative approaches uh to uh to coming 126 00:05:02,870 --> 00:05:00,880 up with new ideas and then following 127 00:05:05,350 --> 00:05:02,880 those ideas through to thinking through 128 00:05:06,629 --> 00:05:05,360 you know what would really face um those 129 00:05:08,710 --> 00:05:06,639 uh those 130 00:05:10,870 --> 00:05:08,720 measurements and the technologies would 131 00:05:12,390 --> 00:05:10,880 be that would be required to be a 132 00:05:14,070 --> 00:05:12,400 reality 133 00:05:15,189 --> 00:05:14,080 fantastic yeah i'm glad to mention these 134 00:05:17,189 --> 00:05:15,199 different communities that are coming 135 00:05:18,950 --> 00:05:17,199 together for this workshop as well you 136 00:05:20,550 --> 00:05:18,960 know a lot of us think about things like 137 00:05:22,390 --> 00:05:20,560 you know engineers tell scientists we 138 00:05:24,070 --> 00:05:22,400 can only land in certain places on mars 139 00:05:25,189 --> 00:05:24,080 but then scientists want to do certain 140 00:05:27,029 --> 00:05:25,199 science and so we have to ask the 141 00:05:29,110 --> 00:05:27,039 engineers what can we do 142 00:05:31,430 --> 00:05:29,120 and so richard for you 143 00:05:33,110 --> 00:05:31,440 what do we actually need to do to 144 00:05:35,189 --> 00:05:33,120 integrate more of this knowledge from 145 00:05:37,189 --> 00:05:35,199 science and engineering 146 00:05:38,629 --> 00:05:37,199 and will this workshop get us there or 147 00:05:40,629 --> 00:05:38,639 what is kind of the long-term product 148 00:05:43,029 --> 00:05:40,639 then from this meeting 149 00:05:45,990 --> 00:05:43,039 well i think that this workshop is is a 150 00:05:47,430 --> 00:05:46,000 start and there are other um you know uh 151 00:05:49,909 --> 00:05:47,440 people working to bring these 152 00:05:53,029 --> 00:05:49,919 communities together and and you know 153 00:05:54,710 --> 00:05:53,039 early on when people were being invited 154 00:05:56,230 --> 00:05:54,720 and started participating they 155 00:05:58,390 --> 00:05:56,240 immediately recognized that there's a 156 00:06:00,950 --> 00:05:58,400 real need to get engineers into the 157 00:06:01,909 --> 00:06:00,960 conversation early i think a lot of 158 00:06:03,510 --> 00:06:01,919 times 159 00:06:05,510 --> 00:06:03,520 you know the scientists they have their 160 00:06:06,870 --> 00:06:05,520 ideas their hypothesis and they pursue 161 00:06:08,790 --> 00:06:06,880 it down a path 162 00:06:10,629 --> 00:06:08,800 and it's uh quite a while before they 163 00:06:12,150 --> 00:06:10,639 actually come back to the reality of how 164 00:06:13,749 --> 00:06:12,160 do you actually implement this and 165 00:06:15,430 --> 00:06:13,759 getting that conversation going with 166 00:06:17,189 --> 00:06:15,440 engineers 167 00:06:18,710 --> 00:06:17,199 so i think that this workshop is a 168 00:06:20,950 --> 00:06:18,720 really good forum for that for bringing 169 00:06:21,909 --> 00:06:20,960 those two groups together 170 00:06:23,189 --> 00:06:21,919 wonderful 171 00:06:25,590 --> 00:06:23,199 so 172 00:06:27,510 --> 00:06:25,600 a little bit with both of you to talk a 173 00:06:30,469 --> 00:06:27,520 little bit about the pathways of 174 00:06:32,070 --> 00:06:30,479 instrument development um so stephanie 175 00:06:34,150 --> 00:06:32,080 what instruments have you personally 176 00:06:35,510 --> 00:06:34,160 been involved with for one thing but 177 00:06:36,710 --> 00:06:35,520 then also what is it like to be a 178 00:06:38,309 --> 00:06:36,720 scientist working with these 179 00:06:40,309 --> 00:06:38,319 technologies that we send to other 180 00:06:41,670 --> 00:06:40,319 worlds and then we have you know years 181 00:06:43,189 --> 00:06:41,680 of data collection bringing that 182 00:06:44,629 --> 00:06:43,199 information back to us 183 00:06:46,390 --> 00:06:44,639 studying it 184 00:06:48,790 --> 00:06:46,400 there are so many questions in that 185 00:06:50,710 --> 00:06:48,800 question graham but i will try to answer 186 00:06:52,870 --> 00:06:50,720 them 187 00:06:54,629 --> 00:06:52,880 so i'll run through the list i guess 188 00:06:57,029 --> 00:06:54,639 i've i've watched um 189 00:07:00,230 --> 00:06:57,039 several instruments get built during my 190 00:07:01,189 --> 00:07:00,240 career at nasa they've primarily been in 191 00:07:02,550 --> 00:07:01,199 situ 192 00:07:04,629 --> 00:07:02,560 analytical 193 00:07:06,150 --> 00:07:04,639 instruments 194 00:07:07,350 --> 00:07:06,160 typically with mass spectrometry 195 00:07:10,150 --> 00:07:07,360 involved 196 00:07:12,790 --> 00:07:10,160 i watched uh the sample analysis at mars 197 00:07:14,550 --> 00:07:12,800 instrument suite get built and delivered 198 00:07:17,110 --> 00:07:14,560 to myers science laboratory and now it's 199 00:07:20,070 --> 00:07:17,120 nearing 10 years of incredible 200 00:07:23,189 --> 00:07:20,080 operations at gale crater on mars um 201 00:07:25,510 --> 00:07:23,199 watched the neutral gas and ion mass 202 00:07:27,029 --> 00:07:25,520 spectrometer engines get developed from 203 00:07:29,430 --> 00:07:27,039 the maven mission which is still 204 00:07:31,189 --> 00:07:29,440 orbiting around mars making discoveries 205 00:07:33,189 --> 00:07:31,199 there um 206 00:07:35,909 --> 00:07:33,199 ionic neutral mass spectrometer for 207 00:07:38,390 --> 00:07:35,919 laddie uh which was an orbiter around 208 00:07:41,749 --> 00:07:38,400 the moon um and then you know i was 209 00:07:43,749 --> 00:07:41,759 really uh in the room for a lot of um 210 00:07:47,350 --> 00:07:43,759 the development of the mars organic 211 00:07:50,950 --> 00:07:47,360 molecule analyzer moma mass spectrometer 212 00:07:53,510 --> 00:07:50,960 which was delivered to the mars rover 213 00:07:56,790 --> 00:07:53,520 and now i have the real privilege to 214 00:07:58,070 --> 00:07:56,800 work in the same groups that are 215 00:08:00,550 --> 00:07:58,080 and with the same groups that are 216 00:08:03,749 --> 00:08:00,560 developing drams the dragonfly mass 217 00:08:06,070 --> 00:08:03,759 spectrometer for uh titan titan moon uh 218 00:08:08,469 --> 00:08:06,080 mission dragonfly um 219 00:08:10,869 --> 00:08:08,479 and you mentioned a deputy pi one of the 220 00:08:12,710 --> 00:08:10,879 two wpi's for davinci 221 00:08:14,950 --> 00:08:12,720 admission to venus and we'll be flying 222 00:08:17,589 --> 00:08:14,960 the venus mass spectrometer on that 223 00:08:21,189 --> 00:08:17,599 probe through the atmosphere uh to the 224 00:08:22,230 --> 00:08:21,199 near surface of venus um so uh so that's 225 00:08:25,270 --> 00:08:22,240 that's 226 00:08:28,309 --> 00:08:25,280 my most direct connection to 227 00:08:30,550 --> 00:08:28,319 in-situ instrumentation for space flight 228 00:08:33,190 --> 00:08:30,560 and then you kind of asked um you know 229 00:08:35,350 --> 00:08:33,200 what does it take to you know to really 230 00:08:37,589 --> 00:08:35,360 develop these things i think of it as 231 00:08:39,110 --> 00:08:37,599 like kind of a series of questions i 232 00:08:42,230 --> 00:08:39,120 promise i will not describe all the 233 00:08:44,070 --> 00:08:42,240 technology readiness levels um right now 234 00:08:46,150 --> 00:08:44,080 which there are nine of them um they're 235 00:08:47,190 --> 00:08:46,160 called trls um but i'm not going to talk 236 00:08:48,630 --> 00:08:47,200 about them 237 00:08:49,990 --> 00:08:48,640 but you can think about a series of 238 00:08:52,150 --> 00:08:50,000 questions like 239 00:08:54,150 --> 00:08:52,160 you know you have a science question 240 00:08:56,070 --> 00:08:54,160 what measurement or piece of measurement 241 00:08:58,230 --> 00:08:56,080 do you want to make to answer that 242 00:09:00,230 --> 00:08:58,240 science question how do you do that with 243 00:09:02,230 --> 00:09:00,240 a particular instrument or a particular 244 00:09:05,190 --> 00:09:02,240 technique does that 245 00:09:07,430 --> 00:09:05,200 technique work in the lab does that 246 00:09:08,790 --> 00:09:07,440 thing measure the other thing you're 247 00:09:11,110 --> 00:09:08,800 trying to measure with sufficient 248 00:09:13,509 --> 00:09:11,120 performance you know can the thing fit 249 00:09:15,509 --> 00:09:13,519 on a spacecraft and if not you have to 250 00:09:16,710 --> 00:09:15,519 probably build a you know a version of 251 00:09:18,870 --> 00:09:16,720 it that does 252 00:09:21,670 --> 00:09:18,880 um to fit within volume and mass and 253 00:09:23,430 --> 00:09:21,680 power requirements of the mission then 254 00:09:24,949 --> 00:09:23,440 you ask does the thing still work after 255 00:09:27,350 --> 00:09:24,959 you make it small enough to fit on a 256 00:09:29,269 --> 00:09:27,360 spacecraft and then you have to test it 257 00:09:30,550 --> 00:09:29,279 under the environments that it will 258 00:09:32,630 --> 00:09:30,560 experience so not only in the 259 00:09:34,870 --> 00:09:32,640 environment of the eventual you know 260 00:09:36,870 --> 00:09:34,880 mission 261 00:09:39,670 --> 00:09:36,880 for operate science operations but also 262 00:09:41,829 --> 00:09:39,680 will it survive launch and will it's if 263 00:09:44,230 --> 00:09:41,839 it has to land does it survive the 264 00:09:46,550 --> 00:09:44,240 landing conditions so you really put i 265 00:09:49,670 --> 00:09:46,560 mean it's a it's a process it takes 266 00:09:51,910 --> 00:09:49,680 years as you might imagine um but uh but 267 00:09:55,030 --> 00:09:51,920 it's but it's logical and it you know in 268 00:09:56,870 --> 00:09:55,040 a series of steps you you just ask these 269 00:09:58,790 --> 00:09:56,880 harder and harder questions of the of 270 00:10:00,790 --> 00:09:58,800 the thing you want to build 271 00:10:01,829 --> 00:10:00,800 that's so awesome i do have to say i'm a 272 00:10:02,790 --> 00:10:01,839 little jealous with all these 273 00:10:04,870 --> 00:10:02,800 instruments you mentioned that you've 274 00:10:06,630 --> 00:10:04,880 had involvement with um 275 00:10:08,310 --> 00:10:06,640 you know being involved around 276 00:10:09,990 --> 00:10:08,320 instruments going to the moon and mars 277 00:10:11,110 --> 00:10:10,000 and venus and all these different places 278 00:10:14,150 --> 00:10:11,120 i mean that's fantastic and then 279 00:10:15,509 --> 00:10:14,160 dragonfly coming up um that's so cool uh 280 00:10:16,710 --> 00:10:15,519 and i love you know that you share with 281 00:10:18,550 --> 00:10:16,720 our audience decided there are some 282 00:10:20,310 --> 00:10:18,560 trade-offs that come into instrument 283 00:10:21,670 --> 00:10:20,320 development and how we actually can 284 00:10:23,670 --> 00:10:21,680 answer the questions that we're sending 285 00:10:25,269 --> 00:10:23,680 these instruments out to do 286 00:10:26,630 --> 00:10:25,279 uh and so richard i'd like to come to 287 00:10:28,630 --> 00:10:26,640 you you mentioned when we were first 288 00:10:30,310 --> 00:10:28,640 prepping for this episode to us 289 00:10:32,470 --> 00:10:30,320 that that instrument development is a 290 00:10:34,389 --> 00:10:32,480 process of try and try again 291 00:10:36,550 --> 00:10:34,399 and i wonder if you can can kind of you 292 00:10:38,230 --> 00:10:36,560 know go deeper on that expound on that 293 00:10:39,910 --> 00:10:38,240 idea a little bit uh with what 294 00:10:41,829 --> 00:10:39,920 instruments you've been involved in and 295 00:10:42,949 --> 00:10:41,839 and how is it a process of try and try 296 00:10:46,310 --> 00:10:42,959 again 297 00:10:47,750 --> 00:10:46,320 uh sure um well um i i can guess i can 298 00:10:50,310 --> 00:10:47,760 start at the beginning which was quite a 299 00:10:52,949 --> 00:10:50,320 while ago um but when i first started in 300 00:10:54,949 --> 00:10:52,959 in this business or in astrobiology i 301 00:10:58,230 --> 00:10:54,959 was dispatched down to 302 00:10:59,030 --> 00:10:58,240 jpl's micro devices lab and i worked on 303 00:11:01,509 --> 00:10:59,040 the 304 00:11:04,069 --> 00:11:01,519 uh mars occident instrument 305 00:11:07,030 --> 00:11:04,079 which was launched on a russian mission 306 00:11:09,110 --> 00:11:07,040 uh unfortunately it it failed uh before 307 00:11:10,949 --> 00:11:09,120 reaching um yeah 308 00:11:12,550 --> 00:11:10,959 there was common back then 309 00:11:14,470 --> 00:11:12,560 um 310 00:11:16,150 --> 00:11:14,480 but but that really started trajectory 311 00:11:18,389 --> 00:11:16,160 for technology development and different 312 00:11:19,509 --> 00:11:18,399 ways to interrogate environments i would 313 00:11:22,550 --> 00:11:19,519 say that it 314 00:11:23,750 --> 00:11:22,560 it it took two paths um the first path 315 00:11:25,750 --> 00:11:23,760 is 316 00:11:27,110 --> 00:11:25,760 the mars oxygen instrument then morphed 317 00:11:32,310 --> 00:11:27,120 into 318 00:11:35,350 --> 00:11:32,320 the mars oxidant instrument and that was 319 00:11:39,030 --> 00:11:35,360 pursued and pushed towards um 320 00:11:40,870 --> 00:11:39,040 implementation on exomars 321 00:11:42,790 --> 00:11:40,880 which was 322 00:11:44,790 --> 00:11:42,800 initially on the payload but then got 323 00:11:48,949 --> 00:11:44,800 de-scoped 324 00:11:51,350 --> 00:11:48,959 but simultaneously in another direction 325 00:11:53,990 --> 00:11:51,360 the mars oxidant experiment was looking 326 00:11:56,069 --> 00:11:54,000 at solid regulated material parallel to 327 00:11:57,430 --> 00:11:56,079 interrogate the service chemistry of 328 00:11:59,750 --> 00:11:57,440 mars 329 00:12:02,150 --> 00:11:59,760 went on a path of developing 330 00:12:03,829 --> 00:12:02,160 the mecca white chemistry experiment 331 00:12:05,269 --> 00:12:03,839 which was eventually launched on the 332 00:12:07,750 --> 00:12:05,279 phoenix mission 333 00:12:10,389 --> 00:12:07,760 um in the interim i was involved in 334 00:12:12,629 --> 00:12:10,399 another a number of 335 00:12:14,470 --> 00:12:12,639 different technologies that 336 00:12:17,030 --> 00:12:14,480 were developed for instance the first 337 00:12:19,509 --> 00:12:17,040 prototype of tega 338 00:12:21,910 --> 00:12:19,519 which was uh the thermal involved gas 339 00:12:24,550 --> 00:12:21,920 analysis which defensively was also 340 00:12:27,990 --> 00:12:24,560 included on the phoenix mission and the 341 00:12:31,350 --> 00:12:28,000 mars oxygen experiment after getting 342 00:12:33,590 --> 00:12:31,360 de-scoped from exomars it was sort of 343 00:12:35,350 --> 00:12:33,600 retooled and finally that technology was 344 00:12:38,230 --> 00:12:35,360 implemented on the first 345 00:12:40,629 --> 00:12:38,240 astrobiology nano satellite mission i'm 346 00:12:43,829 --> 00:12:40,639 looking at how do 347 00:12:45,990 --> 00:12:43,839 biological materials have organics 348 00:12:48,389 --> 00:12:46,000 how are they changed in space 349 00:12:51,030 --> 00:12:48,399 environment and how might we apply that 350 00:12:53,910 --> 00:12:51,040 science to um to what's happening on 351 00:12:56,550 --> 00:12:53,920 other planetary surfaces 352 00:12:58,710 --> 00:12:56,560 yeah very cool 353 00:13:00,389 --> 00:12:58,720 evolution of progress 354 00:13:02,069 --> 00:13:00,399 they might not work sometimes or we 355 00:13:03,430 --> 00:13:02,079 might lose them on launch but we can 356 00:13:05,670 --> 00:13:03,440 still continue you know the research 357 00:13:07,509 --> 00:13:05,680 forward which i appreciate a lot that 358 00:13:09,990 --> 00:13:07,519 reminds me a lot of the the loss of 359 00:13:11,590 --> 00:13:10,000 phobos grunt many years ago uh and the 360 00:13:13,750 --> 00:13:11,600 life disc that many of us had support 361 00:13:15,430 --> 00:13:13,760 from the planetary society going out to 362 00:13:17,670 --> 00:13:15,440 phobos and back i hope to see something 363 00:13:18,629 --> 00:13:17,680 similar in the near future um but you 364 00:13:19,750 --> 00:13:18,639 said to me something in the very 365 00:13:21,590 --> 00:13:19,760 beginning there richard i'd like to come 366 00:13:23,829 --> 00:13:21,600 back to you mentioned environmental 367 00:13:25,350 --> 00:13:23,839 context and i know in talking to you 368 00:13:26,790 --> 00:13:25,360 previously that you've done field work 369 00:13:28,230 --> 00:13:26,800 before you've gone to the atacama and 370 00:13:30,710 --> 00:13:28,240 some other places 371 00:13:32,629 --> 00:13:30,720 i wonder if you could connect to us 372 00:13:34,790 --> 00:13:32,639 some of the challenges one of doing 373 00:13:36,710 --> 00:13:34,800 field work and also how how we make 374 00:13:39,590 --> 00:13:36,720 connections from the field to some of 375 00:13:41,189 --> 00:13:39,600 the missions you've been involved in 376 00:13:43,269 --> 00:13:41,199 um well that's a really interesting 377 00:13:44,870 --> 00:13:43,279 question in terms of the atacama desert 378 00:13:47,670 --> 00:13:44,880 um i think uh 379 00:13:50,230 --> 00:13:47,680 about almost 20 years ago i was down 380 00:13:52,069 --> 00:13:50,240 there with uh raphael navarro gonzalez 381 00:13:54,069 --> 00:13:52,079 and a number of other researchers and 382 00:13:56,470 --> 00:13:54,079 and really um 383 00:13:59,189 --> 00:13:56,480 published the first paper in science you 384 00:14:00,470 --> 00:13:59,199 know that accommodates a mars analog and 385 00:14:03,110 --> 00:14:00,480 sort of set 386 00:14:05,269 --> 00:14:03,120 forth this whole you know trajectory of 387 00:14:08,550 --> 00:14:05,279 research that was done done down in that 388 00:14:11,430 --> 00:14:08,560 field um and and i think that the 389 00:14:13,350 --> 00:14:11,440 the the challenges of doing field work 390 00:14:15,430 --> 00:14:13,360 and how do you apply it to 391 00:14:17,829 --> 00:14:15,440 your science and technology are little 392 00:14:19,829 --> 00:14:17,839 they're two different things uh i think 393 00:14:21,430 --> 00:14:19,839 the technology implementation is a 394 00:14:23,509 --> 00:14:21,440 little more straightforward you go down 395 00:14:25,590 --> 00:14:23,519 the attic 396 00:14:28,949 --> 00:14:25,600 water dirt is very 397 00:14:31,189 --> 00:14:28,959 mars like you know physically it's very 398 00:14:33,670 --> 00:14:31,199 similar to mars 399 00:14:35,670 --> 00:14:33,680 minus atmosphere and things like that 400 00:14:38,150 --> 00:14:35,680 that allows you to do technology 401 00:14:40,949 --> 00:14:38,160 demonstration more challenging is the 402 00:14:43,030 --> 00:14:40,959 science um and in particular say for the 403 00:14:46,230 --> 00:14:43,040 atacama desert the atacama desert is 404 00:14:48,470 --> 00:14:46,240 vast and most of it is not mars-like in 405 00:14:51,269 --> 00:14:48,480 fact you always have to be considering 406 00:14:54,470 --> 00:14:51,279 from the science side um even you know 407 00:14:57,030 --> 00:14:54,480 where it seemingly seems to be like 408 00:14:59,509 --> 00:14:57,040 another planet really how is it and how 409 00:15:01,189 --> 00:14:59,519 is it you know not um and now i think 410 00:15:03,829 --> 00:15:01,199 that's really the challenge i think that 411 00:15:06,470 --> 00:15:03,839 it can uh it can be a little deceptive 412 00:15:08,949 --> 00:15:06,480 you think you're actually you get 413 00:15:11,590 --> 00:15:08,959 mars analog field work but in fact when 414 00:15:13,189 --> 00:15:11,600 you dig down the science or really 415 00:15:15,670 --> 00:15:13,199 fundamental differences that need to be 416 00:15:17,670 --> 00:15:15,680 understood otherwise uh you know when 417 00:15:20,629 --> 00:15:17,680 you do get to your destination you might 418 00:15:24,069 --> 00:15:20,639 be subject to to misinterpretations or 419 00:15:27,350 --> 00:15:24,079 uh you know not complete understanding 420 00:15:33,189 --> 00:15:30,310 biology graphic histories uh for our 421 00:15:35,350 --> 00:15:33,199 artistic works um where we explore some 422 00:15:38,230 --> 00:15:35,360 of the history of astrobiology uh at 423 00:15:40,069 --> 00:15:38,240 nasa uh peter doran is quoted as saying 424 00:15:41,990 --> 00:15:40,079 that analog environments have 425 00:15:43,670 --> 00:15:42,000 life-threatening characteristics that's 426 00:15:44,949 --> 00:15:43,680 what they share with other worlds i 427 00:15:45,990 --> 00:15:44,959 always like to also remind people that 428 00:15:47,990 --> 00:15:46,000 they have life-supporting 429 00:15:50,550 --> 00:15:48,000 characteristics too which is what makes 430 00:15:52,870 --> 00:15:50,560 them kind of habitable systems uh and so 431 00:15:55,509 --> 00:15:52,880 stephanie i wonder for you 432 00:15:57,430 --> 00:15:55,519 um and your role at goddard uh what does 433 00:15:59,030 --> 00:15:57,440 your team do to bring knowledge from 434 00:16:01,749 --> 00:15:59,040 field science into what we're actually 435 00:16:03,430 --> 00:16:01,759 using then to look uh for for life or 436 00:16:04,310 --> 00:16:03,440 for understanding geology in other 437 00:16:06,949 --> 00:16:04,320 worlds 438 00:16:09,590 --> 00:16:06,959 yeah oh i love this question um because 439 00:16:12,150 --> 00:16:09,600 it you know it really ties together 440 00:16:14,949 --> 00:16:12,160 field work is you know is one element of 441 00:16:17,430 --> 00:16:14,959 how you really prepare to go 442 00:16:19,829 --> 00:16:17,440 uh to another destination and your 443 00:16:22,069 --> 00:16:19,839 investigations there we have our um our 444 00:16:24,790 --> 00:16:22,079 gift team goddard instrument field team 445 00:16:27,110 --> 00:16:24,800 with members from ames as well 446 00:16:29,110 --> 00:16:27,120 who go out into a variety of 447 00:16:31,910 --> 00:16:29,120 environments that planetary analog 448 00:16:34,790 --> 00:16:31,920 environments um you know beyond atacama 449 00:16:36,790 --> 00:16:34,800 which is you know a canonical one and a 450 00:16:40,629 --> 00:16:36,800 really great one um but also you know 451 00:16:42,870 --> 00:16:40,639 other other areas to look at uh lunar um 452 00:16:44,710 --> 00:16:42,880 analog environments other mars analog 453 00:16:47,030 --> 00:16:44,720 environments and even you know some 454 00:16:48,550 --> 00:16:47,040 aspects it's really hard to emulate an 455 00:16:51,430 --> 00:16:48,560 ocean world 456 00:16:53,189 --> 00:16:51,440 um perfectly on earth 457 00:16:55,269 --> 00:16:53,199 but there are some regions of earth that 458 00:16:57,910 --> 00:16:55,279 are really hostile 459 00:17:00,389 --> 00:16:57,920 and um and really energy starved and are 460 00:17:02,790 --> 00:17:00,399 good analog environments as well and 461 00:17:04,390 --> 00:17:02,800 kind of represent the interface between 462 00:17:07,510 --> 00:17:04,400 you know maybe ice 463 00:17:10,309 --> 00:17:07,520 water energy sources um you know 464 00:17:11,829 --> 00:17:10,319 substrates in terms of rocks and 465 00:17:13,669 --> 00:17:11,839 mineralogy 466 00:17:15,909 --> 00:17:13,679 and and understanding uh that 467 00:17:18,789 --> 00:17:15,919 environment as a system 468 00:17:20,549 --> 00:17:18,799 really makes field work critical 469 00:17:24,069 --> 00:17:20,559 in putting together the pieces and 470 00:17:26,630 --> 00:17:24,079 practicing what that data interpretation 471 00:17:28,470 --> 00:17:26,640 would be like with even less information 472 00:17:30,230 --> 00:17:28,480 and less of an ability to go and service 473 00:17:32,150 --> 00:17:30,240 your instrument which you have a little 474 00:17:33,990 --> 00:17:32,160 bit ability when you're in the field 475 00:17:36,710 --> 00:17:34,000 right so um 476 00:17:37,830 --> 00:17:36,720 so uh the the teams that go out into the 477 00:17:40,310 --> 00:17:37,840 field 478 00:17:43,029 --> 00:17:40,320 the ones that goddard particularly who 479 00:17:44,789 --> 00:17:43,039 collaborate a lot with outside um 480 00:17:46,470 --> 00:17:44,799 teams as well 481 00:17:49,190 --> 00:17:46,480 they have the opportunity to bring back 482 00:17:51,430 --> 00:17:49,200 relevant samples to our laboratories at 483 00:17:54,390 --> 00:17:51,440 goddard as well we have 484 00:17:56,630 --> 00:17:54,400 chemistry and noble gas laboratories 485 00:17:58,870 --> 00:17:56,640 lots of analytical capabilities that 486 00:18:01,190 --> 00:17:58,880 goddard and with our partners 487 00:18:03,029 --> 00:18:01,200 to really help tease out all of the 488 00:18:04,549 --> 00:18:03,039 different aspects of what uh what a 489 00:18:06,630 --> 00:18:04,559 sample is made out of what the 490 00:18:08,630 --> 00:18:06,640 environment is telling you look at 491 00:18:11,430 --> 00:18:08,640 atmospheric phases you can look at rock 492 00:18:13,430 --> 00:18:11,440 phases you can look at the biology um 493 00:18:15,590 --> 00:18:13,440 and so so that's one benefit of field 494 00:18:18,950 --> 00:18:15,600 work is the sample collection 495 00:18:20,710 --> 00:18:18,960 aspect um you also have your testing uh 496 00:18:23,190 --> 00:18:20,720 in remote environments um that you're 497 00:18:25,830 --> 00:18:23,200 able to do to really put your instrument 498 00:18:27,350 --> 00:18:25,840 uh you know um through some tough 499 00:18:29,990 --> 00:18:27,360 challenges 500 00:18:32,390 --> 00:18:30,000 on the way uh to maturing it um to be 501 00:18:34,470 --> 00:18:32,400 ready for space flight um and then 502 00:18:36,870 --> 00:18:34,480 there's like the operational side there 503 00:18:38,950 --> 00:18:36,880 are advantages um to being out into the 504 00:18:42,150 --> 00:18:38,960 field and testing you know operational 505 00:18:44,630 --> 00:18:42,160 sequences that really respond to the the 506 00:18:47,510 --> 00:18:44,640 um constraints that you have in 507 00:18:49,669 --> 00:18:47,520 planetary exploration on how much you 508 00:18:52,390 --> 00:18:49,679 can do in a particular message mission 509 00:18:56,070 --> 00:18:52,400 how quickly you can do each thing and 510 00:18:59,029 --> 00:18:56,080 how investigations build upon each other 511 00:19:00,789 --> 00:18:59,039 with analysis in between where you can 512 00:19:02,470 --> 00:19:00,799 to really get to the end goal of 513 00:19:03,750 --> 00:19:02,480 answering your your big science 514 00:19:05,830 --> 00:19:03,760 questions 515 00:19:08,150 --> 00:19:05,840 i want to mention one more thing our 516 00:19:10,310 --> 00:19:08,160 gift team has 517 00:19:11,990 --> 00:19:10,320 taken the opportunity to bring students 518 00:19:13,830 --> 00:19:12,000 into the field students not only in 519 00:19:16,470 --> 00:19:13,840 traditional fields but also in 520 00:19:19,590 --> 00:19:16,480 journalism programs and other programs 521 00:19:21,990 --> 00:19:19,600 um to engage uh you know 522 00:19:23,590 --> 00:19:22,000 really all of the diverse disciplines 523 00:19:26,150 --> 00:19:23,600 that you really need to 524 00:19:28,549 --> 00:19:26,160 not only accomplish the science but 525 00:19:31,590 --> 00:19:28,559 communicate that science to a wider 526 00:19:33,029 --> 00:19:31,600 audience it's a really exciting uh it's 527 00:19:35,430 --> 00:19:33,039 a really exciting group to have at 528 00:19:36,390 --> 00:19:35,440 goddard and i'm privileged to work with 529 00:19:38,230 --> 00:19:36,400 them 530 00:19:39,990 --> 00:19:38,240 oh that's so cool now so glad you 531 00:19:41,669 --> 00:19:40,000 mentioned that a lot of our viewers are 532 00:19:43,350 --> 00:19:41,679 high school students undergraduate 533 00:19:45,190 --> 00:19:43,360 students graduate students who are very 534 00:19:47,190 --> 00:19:45,200 interested in how they can become 535 00:19:48,870 --> 00:19:47,200 involved in things like field work and 536 00:19:50,710 --> 00:19:48,880 instrument development and working at 537 00:19:52,549 --> 00:19:50,720 nasa and so it's great to have those 538 00:19:53,590 --> 00:19:52,559 connections for them to hear about 539 00:19:54,950 --> 00:19:53,600 and i do want to come back to something 540 00:19:56,870 --> 00:19:54,960 you mentioned about bringing samples 541 00:19:58,470 --> 00:19:56,880 back when you're in the field and 542 00:20:00,630 --> 00:19:58,480 bringing them back to goddard and other 543 00:20:01,990 --> 00:20:00,640 nasa centers for instance but but one 544 00:20:03,270 --> 00:20:02,000 thing you mentioned there too was this 545 00:20:04,870 --> 00:20:03,280 idea you know we're trying to understand 546 00:20:06,710 --> 00:20:04,880 the characteristics of the environment 547 00:20:08,950 --> 00:20:06,720 and relate that to these other places i 548 00:20:10,149 --> 00:20:08,960 get that question a lot in public talks 549 00:20:11,669 --> 00:20:10,159 when i'm speaking especially with the 550 00:20:13,830 --> 00:20:11,679 filter and then you know how is this 551 00:20:15,830 --> 00:20:13,840 like mars how is this like europa how is 552 00:20:17,830 --> 00:20:15,840 this like venus and they also asked like 553 00:20:20,310 --> 00:20:17,840 big questions and so we wanted to ask a 554 00:20:23,430 --> 00:20:20,320 big question of our twitter audience who 555 00:20:26,149 --> 00:20:23,440 follow along at nasa astrobio on twitter 556 00:20:28,230 --> 00:20:26,159 and we asked them the question of if we 557 00:20:30,070 --> 00:20:28,240 had an unlimited budget which is always 558 00:20:31,909 --> 00:20:30,080 kind of a grand weight hand waving thing 559 00:20:34,870 --> 00:20:31,919 but if we had an unlimited budget with 560 00:20:36,950 --> 00:20:34,880 nasa what scientific instrument would 561 00:20:39,750 --> 00:20:36,960 you develop to search for life beyond 562 00:20:42,230 --> 00:20:39,760 earth and we had so many really 563 00:20:44,310 --> 00:20:42,240 intriguing answers uh dr shawn 564 00:20:46,789 --> 00:20:44,320 damogoldman came on 565 00:20:48,310 --> 00:20:46,799 and mentioned the lavoir telescope which 566 00:20:50,390 --> 00:20:48,320 we have this idea to build a very cool 567 00:20:52,470 --> 00:20:50,400 large telescope that can look in uv 568 00:20:54,070 --> 00:20:52,480 infrared visible light and and do some 569 00:20:55,830 --> 00:20:54,080 really cool things uh several other 570 00:20:58,230 --> 00:20:55,840 people mentioned large telescopes like 571 00:21:00,310 --> 00:20:58,240 arecibo or building large telescopes in 572 00:21:02,230 --> 00:21:00,320 space we had people mention drilling 573 00:21:04,630 --> 00:21:02,240 through the ice on europa and different 574 00:21:06,549 --> 00:21:04,640 kinds of drills dr pauly lane 575 00:21:08,950 --> 00:21:06,559 from finland mentioned using a terahertz 576 00:21:11,830 --> 00:21:08,960 detector to explore biosignatures and 577 00:21:13,430 --> 00:21:11,840 watery plumes from enceladus dr option 578 00:21:15,029 --> 00:21:13,440 khan mentioned 579 00:21:16,950 --> 00:21:15,039 building a high-end instrument for 580 00:21:18,710 --> 00:21:16,960 looking at chirality and even for 581 00:21:20,789 --> 00:21:18,720 concentrating biomolecules or 582 00:21:22,870 --> 00:21:20,799 biosignatures which i thought was pretty 583 00:21:25,510 --> 00:21:22,880 cool we had several answers like things 584 00:21:28,149 --> 00:21:25,520 like warp drive um you know some higher 585 00:21:29,750 --> 00:21:28,159 end stuff that's kind of out there um 586 00:21:30,789 --> 00:21:29,760 maybe the funniest ones though we had 587 00:21:33,990 --> 00:21:30,799 one person mentioned that they would 588 00:21:35,909 --> 00:21:34,000 build a hal 9000 um which that'd be 589 00:21:38,390 --> 00:21:35,919 interesting like in 2001 a space odyssey 590 00:21:41,190 --> 00:21:38,400 let's just not lie to it um and then 591 00:21:42,710 --> 00:21:41,200 someone else chris colosse uh shared 592 00:21:44,549 --> 00:21:42,720 with us a picture from pirates of the 593 00:21:45,990 --> 00:21:44,559 caribbean at world's end where the two 594 00:21:48,390 --> 00:21:46,000 captains are battling over who has the 595 00:21:49,590 --> 00:21:48,400 longest telescope um which i thought was 596 00:21:50,789 --> 00:21:49,600 kind of interesting for some of what 597 00:21:53,990 --> 00:21:50,799 we've done in the past in building 598 00:21:56,230 --> 00:21:54,000 really big telescopes um so for both of 599 00:21:59,270 --> 00:21:56,240 you just a fun question if you had an 600 00:22:01,510 --> 00:21:59,280 unlimited budget um what instrument 601 00:22:02,549 --> 00:22:01,520 would you want to build and send out 602 00:22:04,220 --> 00:22:02,559 there 603 00:22:08,870 --> 00:22:04,230 stephanie how about you 604 00:22:13,990 --> 00:22:11,750 so much of my life is like responding to 605 00:22:17,990 --> 00:22:14,000 the constraints that are put on me this 606 00:22:21,750 --> 00:22:19,350 whatever you think you could imagine 607 00:22:22,549 --> 00:22:21,760 would be awesome 608 00:22:30,470 --> 00:22:22,559 i 609 00:22:34,789 --> 00:22:31,990 because they really complement each 610 00:22:38,549 --> 00:22:34,799 other you know look at mineralogy 611 00:22:41,669 --> 00:22:38,559 petrology you know the organic chemistry 612 00:22:43,750 --> 00:22:41,679 from various angles prebiotic chemistry 613 00:22:46,630 --> 00:22:43,760 what can be biological you know what can 614 00:22:49,510 --> 00:22:46,640 you tell um from the refractory uh 615 00:22:51,590 --> 00:22:49,520 components of the organic composition um 616 00:22:53,350 --> 00:22:51,600 what about the atmospheric chemistry 617 00:22:54,470 --> 00:22:53,360 what about the noble gases what can they 618 00:22:56,390 --> 00:22:54,480 tell you about the evolution of a 619 00:22:59,110 --> 00:22:56,400 particular planetary body where it came 620 00:23:00,630 --> 00:22:59,120 from what's happened to it um all that 621 00:23:03,029 --> 00:23:00,640 ultimately 622 00:23:05,590 --> 00:23:03,039 our goal right is to 623 00:23:08,549 --> 00:23:05,600 is to build upon mission 624 00:23:10,870 --> 00:23:08,559 ask question upon question to answer as 625 00:23:12,390 --> 00:23:10,880 many of these questions as possible so 626 00:23:15,270 --> 00:23:12,400 that we know as much as possible and 627 00:23:17,110 --> 00:23:15,280 we're as confident as possible about the 628 00:23:18,789 --> 00:23:17,120 conclusions and interpretations that 629 00:23:22,070 --> 00:23:18,799 we're drawing from the data sets that we 630 00:23:24,390 --> 00:23:22,080 have which are just by nature limited um 631 00:23:25,510 --> 00:23:24,400 uh when uh when you when you work 632 00:23:27,909 --> 00:23:25,520 in situ 633 00:23:29,590 --> 00:23:27,919 the finite volume power 634 00:23:31,350 --> 00:23:29,600 absolutely and there's so many cool 635 00:23:33,110 --> 00:23:31,360 concepts and things being developed out 636 00:23:35,590 --> 00:23:33,120 there i would toss in the uranus and 637 00:23:37,590 --> 00:23:35,600 neptune missions as well just for fun um 638 00:23:39,350 --> 00:23:37,600 richard how about you unlimited budget 639 00:23:41,510 --> 00:23:39,360 what would you build 640 00:23:43,110 --> 00:23:41,520 um well if i had an unlimited budget i 641 00:23:44,870 --> 00:23:43,120 might approach it a little differently 642 00:23:47,029 --> 00:23:44,880 you know i i think the ideas that we 643 00:23:48,950 --> 00:23:47,039 just heard coming in from the community 644 00:23:51,669 --> 00:23:48,960 are fantastic and that's really the 645 00:23:54,310 --> 00:23:51,679 purpose of the workshop to get new ideas 646 00:23:56,149 --> 00:23:54,320 and there are different combinations of 647 00:23:59,110 --> 00:23:56,159 instruments approaches that you could 648 00:24:01,669 --> 00:23:59,120 use for you know searching for life and 649 00:24:04,070 --> 00:24:01,679 they might vary depending on your target 650 00:24:06,470 --> 00:24:04,080 if i had an unlimited budget though i 651 00:24:08,470 --> 00:24:06,480 honestly would probably take a core set 652 00:24:10,310 --> 00:24:08,480 of instruments and really we've been 653 00:24:12,950 --> 00:24:10,320 thinking about this for a long time so 654 00:24:16,070 --> 00:24:12,960 we have some really solid approaches 655 00:24:17,510 --> 00:24:16,080 and rather than spend a lot of money on 656 00:24:20,070 --> 00:24:17,520 you know developing an instrument i 657 00:24:22,950 --> 00:24:20,080 would spend that money to make many many 658 00:24:25,350 --> 00:24:22,960 many copies of that same instrument and 659 00:24:27,110 --> 00:24:25,360 send it to many many many places so i 660 00:24:28,470 --> 00:24:27,120 think that the need in terms of budget 661 00:24:30,310 --> 00:24:28,480 is actually 662 00:24:33,029 --> 00:24:30,320 more missions 663 00:24:36,230 --> 00:24:33,039 rather than necessarily bigger budget 664 00:24:38,390 --> 00:24:36,240 for instruments um you know the the more 665 00:24:40,470 --> 00:24:38,400 we can look the frequency that we can 666 00:24:42,149 --> 00:24:40,480 look increases the probability of 667 00:24:44,549 --> 00:24:42,159 success so that's how i would spend the 668 00:24:46,470 --> 00:24:44,559 money instead of a mission every couple 669 00:24:47,350 --> 00:24:46,480 of years i would have a mission every 670 00:24:50,230 --> 00:24:47,360 month 671 00:24:51,590 --> 00:24:50,240 oh interesting i love that one 672 00:24:52,950 --> 00:24:51,600 budget right so we can just you know we 673 00:24:56,149 --> 00:24:52,960 can do a mission every month and that's 674 00:24:57,350 --> 00:24:56,159 fantastic i love it um so i i do have a 675 00:24:58,630 --> 00:24:57,360 few more minutes in my own questioning 676 00:25:00,549 --> 00:24:58,640 here with you i want to remind our 677 00:25:02,870 --> 00:25:00,559 audience watching on youtube that you 678 00:25:03,990 --> 00:25:02,880 can ask questions in the chat right now 679 00:25:05,990 --> 00:25:04,000 and they will come through to my 680 00:25:07,430 --> 00:25:06,000 teleprompter for me to ask of doctors 681 00:25:09,110 --> 00:25:07,440 getty and quinn 682 00:25:10,950 --> 00:25:09,120 i see some questions coming in already 683 00:25:12,710 --> 00:25:10,960 so please keep those coming 684 00:25:14,310 --> 00:25:12,720 i want to come back now stephanie you 685 00:25:16,470 --> 00:25:14,320 mentioned this idea of bringing samples 686 00:25:18,390 --> 00:25:16,480 back from the field to maybe our you 687 00:25:20,310 --> 00:25:18,400 know our higher precision higher end 688 00:25:22,230 --> 00:25:20,320 instrumentation that we have in the 689 00:25:24,470 --> 00:25:22,240 laboratory at nasa centers and other 690 00:25:26,789 --> 00:25:24,480 institutions um but you know when it 691 00:25:28,630 --> 00:25:26,799 comes to returning samples from space 692 00:25:30,549 --> 00:25:28,640 that's a much different process it's far 693 00:25:32,470 --> 00:25:30,559 more expensive there's infrastructure 694 00:25:34,310 --> 00:25:32,480 that has to be built around getting 695 00:25:36,149 --> 00:25:34,320 missions out there to collect samples 696 00:25:37,669 --> 00:25:36,159 and bring them back and in the case of 697 00:25:39,029 --> 00:25:37,679 mars for instance there's a large 698 00:25:40,950 --> 00:25:39,039 infrastructure that we still have to 699 00:25:43,190 --> 00:25:40,960 develop to to get samples back from 700 00:25:44,310 --> 00:25:43,200 perseverance right now i'm wondering if 701 00:25:46,630 --> 00:25:44,320 you could talk a bit about the 702 00:25:48,470 --> 00:25:46,640 trade-offs of you know developing these 703 00:25:49,909 --> 00:25:48,480 infrastructures for sample return 704 00:25:52,149 --> 00:25:49,919 compared to developing better 705 00:25:53,029 --> 00:25:52,159 infrastructure for instrumentation in 706 00:25:56,230 --> 00:25:53,039 space 707 00:25:58,630 --> 00:25:56,240 yeah i mean the answer is both please um 708 00:26:00,950 --> 00:25:58,640 obviously we can do so much 709 00:26:03,029 --> 00:26:00,960 with laboratory instruments that just 710 00:26:05,430 --> 00:26:03,039 can't be done 711 00:26:07,029 --> 00:26:05,440 but at the same time when you're 712 00:26:09,750 --> 00:26:07,039 exploring 713 00:26:11,190 --> 00:26:09,760 scientifically a new environment um you 714 00:26:13,269 --> 00:26:11,200 know i think 715 00:26:15,350 --> 00:26:13,279 the best approach is really an interplay 716 00:26:17,110 --> 00:26:15,360 between in-situ emissions and sample 717 00:26:18,870 --> 00:26:17,120 return missions where is possible i mean 718 00:26:20,789 --> 00:26:18,880 there are some sample return missions 719 00:26:22,630 --> 00:26:20,799 that are kind of beyond uh near-term 720 00:26:25,190 --> 00:26:22,640 capabilities obviously just for 721 00:26:27,669 --> 00:26:25,200 proximity reasons um 722 00:26:29,510 --> 00:26:27,679 but even for return missions i mean 723 00:26:31,029 --> 00:26:29,520 without the in-situ 724 00:26:32,549 --> 00:26:31,039 science it can be really hard to 725 00:26:34,310 --> 00:26:32,559 convince yourself that you're going to 726 00:26:35,830 --> 00:26:34,320 the right location i mean 727 00:26:37,350 --> 00:26:35,840 that you're picking up the best sample 728 00:26:38,950 --> 00:26:37,360 for return to earth and as you know 729 00:26:41,350 --> 00:26:38,960 there's a lot as you mentioned graham 730 00:26:43,669 --> 00:26:41,360 there's a lot riding on that return 731 00:26:45,110 --> 00:26:43,679 right so you want to know enough 732 00:26:46,470 --> 00:26:45,120 about the environment to be able to 733 00:26:48,470 --> 00:26:46,480 interpret the results like we were 734 00:26:50,470 --> 00:26:48,480 talking about before and that can't be 735 00:26:53,110 --> 00:26:50,480 done without thinking about the science 736 00:26:55,269 --> 00:26:53,120 of the system and so that really 737 00:26:57,669 --> 00:26:55,279 requires sustained questioning of like 738 00:27:00,470 --> 00:26:57,679 what what that system is and how it came 739 00:27:03,190 --> 00:27:00,480 to be and how it's different from other 740 00:27:05,029 --> 00:27:03,200 places we've seen before and 741 00:27:07,669 --> 00:27:05,039 you know richard you mentioned too all 742 00:27:10,549 --> 00:27:07,679 planetary environments are not one thing 743 00:27:12,310 --> 00:27:10,559 about mars and how varied the surface 744 00:27:15,110 --> 00:27:12,320 geology is and we we haven't even 745 00:27:17,110 --> 00:27:15,120 started to explore the subsurface right 746 00:27:19,190 --> 00:27:17,120 and we think about an ocean world like 747 00:27:22,310 --> 00:27:19,200 enceladus um there are several 748 00:27:24,710 --> 00:27:22,320 environmental targets there um the plume 749 00:27:26,710 --> 00:27:24,720 at the southern pole the icy surface 750 00:27:29,430 --> 00:27:26,720 that expresses signatures of the ocean 751 00:27:32,149 --> 00:27:29,440 potentially directly visiting the ocean 752 00:27:33,830 --> 00:27:32,159 um you know in the future so no single 753 00:27:36,149 --> 00:27:33,840 mission can visit all of those 754 00:27:37,430 --> 00:27:36,159 environments in situ but we we have to 755 00:27:38,710 --> 00:27:37,440 like be 756 00:27:40,350 --> 00:27:38,720 um 757 00:27:44,870 --> 00:27:40,360 we have to be 758 00:27:47,430 --> 00:27:44,880 our curiosity has to 759 00:27:48,950 --> 00:27:47,440 be somewhat happy with building upon 760 00:27:50,950 --> 00:27:48,960 those questions that 761 00:27:53,269 --> 00:27:50,960 get answered you know in a sequential 762 00:27:55,029 --> 00:27:53,279 way um with missions building upon 763 00:27:56,710 --> 00:27:55,039 previous missions and then you know 764 00:27:58,310 --> 00:27:56,720 getting inspired by the next set of 765 00:28:00,950 --> 00:27:58,320 questions um 766 00:28:02,870 --> 00:28:00,960 so i i think that there's definitely 767 00:28:05,590 --> 00:28:02,880 a good role and 768 00:28:07,269 --> 00:28:05,600 importance to um to both in situ and 769 00:28:08,950 --> 00:28:07,279 sample return 770 00:28:10,549 --> 00:28:08,960 i love that so much and i love that you 771 00:28:12,230 --> 00:28:10,559 have missions building upon admissions 772 00:28:13,990 --> 00:28:12,240 and kind of you know expanding what we 773 00:28:15,029 --> 00:28:14,000 know and and you know what you said 774 00:28:17,029 --> 00:28:15,039 there are two kind of minds this 775 00:28:18,710 --> 00:28:17,039 importance of context in in the 776 00:28:20,630 --> 00:28:18,720 environment and understanding where 777 00:28:21,990 --> 00:28:20,640 these examples come from all three of us 778 00:28:24,549 --> 00:28:22,000 are part of the center for life 779 00:28:26,710 --> 00:28:24,559 detection uh headquartered at nasa ames 780 00:28:28,870 --> 00:28:26,720 which is one of the three main pieces of 781 00:28:30,549 --> 00:28:28,880 the network for life detection or enfold 782 00:28:31,830 --> 00:28:30,559 um you know and with the center for life 783 00:28:32,950 --> 00:28:31,840 detection right now we're building 784 00:28:34,870 --> 00:28:32,960 something called the life detection 785 00:28:36,310 --> 00:28:34,880 knowledge base which will allow 786 00:28:39,110 --> 00:28:36,320 scientists in the community to come 787 00:28:41,110 --> 00:28:39,120 together and to explore not just you 788 00:28:43,350 --> 00:28:41,120 know the the biogenicity of certain 789 00:28:44,789 --> 00:28:43,360 features but also their context which is 790 00:28:46,389 --> 00:28:44,799 really important 791 00:28:47,830 --> 00:28:46,399 and richard for for you you're not only 792 00:28:49,430 --> 00:28:47,840 a part of the center for life detection 793 00:28:50,230 --> 00:28:49,440 but also on the steering committee for 794 00:28:51,830 --> 00:28:50,240 now 795 00:28:55,190 --> 00:28:51,840 um i wonder if you could talk a bit 796 00:28:57,430 --> 00:28:55,200 about um the maybe the the challenges of 797 00:28:59,110 --> 00:28:57,440 taking instruments to icy worlds and 798 00:29:00,870 --> 00:28:59,120 using them in those places and in the 799 00:29:02,149 --> 00:29:00,880 context of those environments which are 800 00:29:04,070 --> 00:29:02,159 very different from the environments we 801 00:29:06,230 --> 00:29:04,080 have here on earth 802 00:29:07,909 --> 00:29:06,240 sure absolutely but if one i would like 803 00:29:10,470 --> 00:29:07,919 to just add a little bit to the question 804 00:29:13,990 --> 00:29:10,480 that you that you posed to stephanie 805 00:29:15,750 --> 00:29:14,000 because as a you know uh 806 00:29:18,149 --> 00:29:15,760 somebody who's 807 00:29:20,950 --> 00:29:18,159 his career has been in situ exploration 808 00:29:24,070 --> 00:29:20,960 now initially sample return i thought 809 00:29:25,269 --> 00:29:24,080 well it's expensive it's unnecessary 810 00:29:27,110 --> 00:29:25,279 but my 811 00:29:28,789 --> 00:29:27,120 thought has shifted over years because i 812 00:29:30,230 --> 00:29:28,799 think what we've learned from mars 813 00:29:33,750 --> 00:29:30,240 exploration 814 00:29:38,630 --> 00:29:36,870 an expression of the presence of life is 815 00:29:41,909 --> 00:29:38,640 going to be subtle 816 00:29:44,549 --> 00:29:41,919 um and so that makes it important to 817 00:29:47,110 --> 00:29:44,559 bring samples back because as much as we 818 00:29:48,470 --> 00:29:47,120 learn uh with in-situ instruments and 819 00:29:50,870 --> 00:29:48,480 even if we 820 00:29:53,029 --> 00:29:50,880 uh you know when we hit on a signal and 821 00:29:53,990 --> 00:29:53,039 we think okay we've done it we've found 822 00:29:55,269 --> 00:29:54,000 it 823 00:29:57,110 --> 00:29:55,279 still those 824 00:29:59,029 --> 00:29:57,120 it has to be confirmed and i think that 825 00:30:01,909 --> 00:29:59,039 confirmation really does need to be done 826 00:30:04,549 --> 00:30:01,919 in the laboratory um so i am like 827 00:30:07,510 --> 00:30:04,559 stephanie said i think both are hand in 828 00:30:09,750 --> 00:30:07,520 hand um now the question about ocean 829 00:30:12,470 --> 00:30:09,760 worlds and and in recent years i have 830 00:30:14,710 --> 00:30:12,480 pivoted um you know to to looking 831 00:30:15,750 --> 00:30:14,720 farther out to those types of missions 832 00:30:16,950 --> 00:30:15,760 and 833 00:30:19,269 --> 00:30:16,960 um 834 00:30:21,269 --> 00:30:19,279 again going into you know environmental 835 00:30:23,110 --> 00:30:21,279 context of course the 836 00:30:25,510 --> 00:30:23,120 the environments are 837 00:30:27,909 --> 00:30:25,520 radically different compared to how we 838 00:30:29,909 --> 00:30:27,919 would explore for say for mars 839 00:30:32,389 --> 00:30:29,919 exploration particularly 840 00:30:34,470 --> 00:30:32,399 um a destination like the european 841 00:30:36,070 --> 00:30:34,480 surface which was a 842 00:30:37,590 --> 00:30:36,080 focus of a potential mission in the 843 00:30:39,590 --> 00:30:37,600 future where you have this incredible 844 00:30:41,430 --> 00:30:39,600 radiation 845 00:30:43,510 --> 00:30:41,440 environment that really 846 00:30:45,029 --> 00:30:43,520 alters and distorts 847 00:30:48,070 --> 00:30:45,039 um you know 848 00:30:50,789 --> 00:30:48,080 any feature or any artifact that you may 849 00:30:51,909 --> 00:30:50,799 expect to see relative to the presence 850 00:30:54,310 --> 00:30:51,919 of life 851 00:30:55,669 --> 00:30:54,320 and you know going back i think we see 852 00:30:59,029 --> 00:30:55,679 on mars 853 00:31:01,909 --> 00:30:59,039 um the the tremendous um challenges that 854 00:31:03,909 --> 00:31:01,919 the radiation environment imposes on the 855 00:31:05,669 --> 00:31:03,919 search for life or even just doing the 856 00:31:08,149 --> 00:31:05,679 science there from the whole 857 00:31:09,590 --> 00:31:08,159 uh elevated oxidation chemistry the 858 00:31:11,190 --> 00:31:09,600 chlorate the 859 00:31:13,269 --> 00:31:11,200 um the 860 00:31:15,990 --> 00:31:13,279 search for organic signatures that have 861 00:31:18,630 --> 00:31:16,000 been altered both 862 00:31:21,669 --> 00:31:18,640 in the environment and also in the 863 00:31:23,430 --> 00:31:21,679 sample processing during um 864 00:31:26,470 --> 00:31:23,440 during exploration 865 00:31:28,470 --> 00:31:26,480 those challenges are just compounded 866 00:31:29,909 --> 00:31:28,480 when we move out to ocean worlds 867 00:31:33,669 --> 00:31:29,919 particularly 868 00:31:34,710 --> 00:31:33,679 moving out to a place like europa 869 00:31:37,110 --> 00:31:34,720 very cool 870 00:31:41,110 --> 00:31:39,430 with cassini very lucky to have the iron 871 00:31:42,870 --> 00:31:41,120 and neutral mass spectrometer on because 872 00:31:44,789 --> 00:31:42,880 you could actually fly through these 873 00:31:46,470 --> 00:31:44,799 plumes of water and there might be 874 00:31:47,830 --> 00:31:46,480 something from europa it's not of the 875 00:31:49,830 --> 00:31:47,840 question there's actually some data that 876 00:31:51,269 --> 00:31:49,840 has suggested there could be european 877 00:31:52,870 --> 00:31:51,279 plumes as well 878 00:31:54,230 --> 00:31:52,880 um and so one instrument for instance 879 00:31:56,230 --> 00:31:54,240 being developed for europa clipper 880 00:31:58,230 --> 00:31:56,240 called suda uh could could not just 881 00:32:00,630 --> 00:31:58,240 explore the dust and materials around 882 00:32:02,549 --> 00:32:00,640 europa but also potentially explore for 883 00:32:04,230 --> 00:32:02,559 plumes there and so there's a bit of 884 00:32:06,070 --> 00:32:04,240 serendipity too that comes into this 885 00:32:08,149 --> 00:32:06,080 right with discovering plumes from an 886 00:32:09,830 --> 00:32:08,159 ocean world that we didn't expect and 887 00:32:11,509 --> 00:32:09,840 who knows if we go to uranus or neptune 888 00:32:13,350 --> 00:32:11,519 what other weird things are happening on 889 00:32:14,870 --> 00:32:13,360 moons in our solar system that we have 890 00:32:16,950 --> 00:32:14,880 no idea about 891 00:32:18,230 --> 00:32:16,960 so i wonder for both of you 892 00:32:19,750 --> 00:32:18,240 before i open it up to the audience 893 00:32:21,830 --> 00:32:19,760 questions here if we could just briefly 894 00:32:24,230 --> 00:32:21,840 talk about the future of instrument 895 00:32:25,669 --> 00:32:24,240 development and data analysis 896 00:32:28,070 --> 00:32:25,679 what are the key things you think we 897 00:32:30,070 --> 00:32:28,080 should be prepared for or maybe be open 898 00:32:32,230 --> 00:32:30,080 to in the very near future 899 00:32:32,950 --> 00:32:32,240 um and stephanie i think i'll start with 900 00:32:37,990 --> 00:32:32,960 you 901 00:32:38,789 --> 00:32:38,000 are key things we should be prepared for 902 00:32:40,230 --> 00:32:38,799 yeah 903 00:32:43,029 --> 00:32:40,240 um i 904 00:32:44,070 --> 00:32:43,039 you know i think go 905 00:32:47,750 --> 00:32:44,080 moving 906 00:32:48,470 --> 00:32:47,760 forward in um in in situ analysis i 907 00:32:51,430 --> 00:32:48,480 think 908 00:32:52,389 --> 00:32:51,440 what you touched on there graham with um 909 00:32:55,110 --> 00:32:52,399 being 910 00:32:58,470 --> 00:32:55,120 prepared for what the what the uh what 911 00:33:01,269 --> 00:32:58,480 the environment has to present to you uh 912 00:33:01,990 --> 00:33:01,279 and being able to um you know to adapt 913 00:33:03,350 --> 00:33:02,000 to 914 00:33:04,710 --> 00:33:03,360 uh 915 00:33:06,470 --> 00:33:04,720 really what this 916 00:33:08,789 --> 00:33:06,480 what the sampling 917 00:33:10,630 --> 00:33:08,799 uh needs to look like to get the right 918 00:33:13,750 --> 00:33:10,640 sample into 919 00:33:16,149 --> 00:33:13,760 into your instrumentation uh is is a 920 00:33:18,310 --> 00:33:16,159 really important factor 921 00:33:20,789 --> 00:33:18,320 i think that for you know as we become 922 00:33:24,789 --> 00:33:20,799 more sophisticated in the way that we 923 00:33:27,430 --> 00:33:24,799 explore certain environments um we we 924 00:33:28,789 --> 00:33:27,440 have the opportunity to you know build 925 00:33:30,789 --> 00:33:28,799 from um 926 00:33:33,350 --> 00:33:30,799 you know kind of you know an approach 927 00:33:35,190 --> 00:33:33,360 where you learn what you can from a 928 00:33:37,269 --> 00:33:35,200 particular fraction that's accessible 929 00:33:39,430 --> 00:33:37,279 with what with the instrumentation that 930 00:33:42,549 --> 00:33:39,440 you have to trying to get the most ease 931 00:33:44,230 --> 00:33:42,559 out the most information out of um out 932 00:33:45,909 --> 00:33:44,240 of the samples that are accessible so 933 00:33:47,269 --> 00:33:45,919 that means you know paying really close 934 00:33:51,190 --> 00:33:47,279 attention to 935 00:33:52,789 --> 00:33:51,200 how cleanly you're sampling um how 936 00:33:54,870 --> 00:33:52,799 how carefully you're treating that 937 00:33:57,509 --> 00:33:54,880 sample as you're moving it between 938 00:34:00,710 --> 00:33:57,519 different elements of um of a payload 939 00:34:03,190 --> 00:34:00,720 for example making taking great care not 940 00:34:05,029 --> 00:34:03,200 to alter that sample and and confusing 941 00:34:06,789 --> 00:34:05,039 yourself what you're seeing at the end 942 00:34:09,510 --> 00:34:06,799 of the day and then just really making 943 00:34:12,950 --> 00:34:09,520 the most of all that sample has to offer 944 00:34:14,069 --> 00:34:12,960 to you um i think um 945 00:34:16,790 --> 00:34:14,079 you know i think 946 00:34:20,310 --> 00:34:16,800 there's there's a there's an evolution 947 00:34:23,589 --> 00:34:20,320 in instrumentation um and uh and i'm 948 00:34:25,750 --> 00:34:23,599 really excited to see the energy um that 949 00:34:27,589 --> 00:34:25,760 uh that we're hearing in this workshop 950 00:34:30,230 --> 00:34:27,599 and from the community and really 951 00:34:32,470 --> 00:34:30,240 treating the hard problems about how to 952 00:34:34,470 --> 00:34:32,480 get um the right sample and the right 953 00:34:35,990 --> 00:34:34,480 fidelity of sample into our 954 00:34:37,510 --> 00:34:36,000 instrumentation 955 00:34:41,669 --> 00:34:37,520 yeah it's always the scientists right 956 00:34:43,750 --> 00:34:41,679 samples um it reminds me an avatar 957 00:34:44,950 --> 00:34:43,760 did we get samples you know we need to 958 00:34:46,069 --> 00:34:44,960 know the samples we also need to know 959 00:34:47,750 --> 00:34:46,079 where they come from and how they've 960 00:34:48,710 --> 00:34:47,760 been treated and i really appreciate 961 00:34:50,149 --> 00:34:48,720 that 962 00:34:51,990 --> 00:34:50,159 um richard how about you what do you 963 00:34:53,030 --> 00:34:52,000 think is the future for for instrument 964 00:34:55,510 --> 00:34:53,040 development 965 00:34:57,030 --> 00:34:55,520 well i i agree 100 with what stephanie 966 00:34:58,630 --> 00:34:57,040 just said i think you know a lot of 967 00:35:00,069 --> 00:34:58,640 times when we talk about instruments 968 00:35:01,349 --> 00:35:00,079 you'll hear people say well my 969 00:35:04,150 --> 00:35:01,359 instrument has 970 00:35:06,230 --> 00:35:04,160 a sensitivity of parts per trillion 971 00:35:07,910 --> 00:35:06,240 or you know it can do this 972 00:35:09,270 --> 00:35:07,920 that and really what you're talking 973 00:35:10,390 --> 00:35:09,280 about there is i'm talking about the 974 00:35:12,390 --> 00:35:10,400 detector 975 00:35:14,150 --> 00:35:12,400 they're you know so they're summing up 976 00:35:16,310 --> 00:35:14,160 their instrument in terms of the 977 00:35:20,069 --> 00:35:16,320 detector but stephanie just pointed out 978 00:35:22,870 --> 00:35:20,079 really the challenges is sample access 979 00:35:24,150 --> 00:35:22,880 sample handling and sample processing 980 00:35:26,390 --> 00:35:24,160 because if you have an instrument 981 00:35:28,470 --> 00:35:26,400 particularly you know an in-situ 982 00:35:31,190 --> 00:35:28,480 instrument that needs to ingest or it 983 00:35:32,470 --> 00:35:31,200 needs to take a sample uh to get a 984 00:35:34,710 --> 00:35:32,480 result 985 00:35:37,430 --> 00:35:34,720 the form of that sample is really what 986 00:35:39,270 --> 00:35:37,440 drives your ability to make a proper 987 00:35:42,230 --> 00:35:39,280 analysis and proper interpretation of 988 00:35:46,230 --> 00:35:42,240 the data so i agree 100 the real 989 00:35:49,430 --> 00:35:46,240 challenges is to future exploration is 990 00:35:51,109 --> 00:35:49,440 is the sample um acquisition sample 991 00:35:53,349 --> 00:35:51,119 processing 992 00:35:55,030 --> 00:35:53,359 very cool uh i i 993 00:35:57,030 --> 00:35:55,040 i view so much right now and i have so 994 00:35:58,870 --> 00:35:57,040 many more questions of my own but i also 995 00:36:00,790 --> 00:35:58,880 have to be a good host and respect our 996 00:36:03,109 --> 00:36:00,800 audience and allow them to ask some 997 00:36:05,430 --> 00:36:03,119 questions too and when one actually came 998 00:36:06,950 --> 00:36:05,440 to us through an email at info 999 00:36:08,950 --> 00:36:06,960 secondnet.org 1000 00:36:11,910 --> 00:36:08,960 was from a person who i know named bob 1001 00:36:14,069 --> 00:36:11,920 bruner he's an 83 year old man who works 1002 00:36:15,430 --> 00:36:14,079 as a volunteer at our local museum 1003 00:36:17,910 --> 00:36:15,440 here in denver the denver museum of 1004 00:36:20,150 --> 00:36:17,920 nature and science he's been developing 1005 00:36:21,829 --> 00:36:20,160 this idea for some time of sharing with 1006 00:36:24,310 --> 00:36:21,839 children and families the kinds of 1007 00:36:25,829 --> 00:36:24,320 minerals we look for on mars but he 1008 00:36:28,630 --> 00:36:25,839 wanted to know since it's not his area 1009 00:36:31,510 --> 00:36:28,640 of expertise um about spectrometers that 1010 00:36:34,710 --> 00:36:31,520 we use in orbit and i wonder if you 1011 00:36:36,310 --> 00:36:34,720 could speak maybe to remote sensing uh 1012 00:36:38,310 --> 00:36:36,320 from orbit or you know even from 1013 00:36:42,230 --> 00:36:38,320 telescopes from far away compared to 1014 00:36:45,109 --> 00:36:43,430 and that could be for either of you 1015 00:36:47,430 --> 00:36:45,119 honestly 1016 00:36:49,670 --> 00:36:47,440 well i mean 1017 00:36:51,670 --> 00:36:49,680 i'll take a step here i mean that's a 1018 00:36:53,910 --> 00:36:51,680 tough question because i am really an 1019 00:36:57,430 --> 00:36:53,920 institute you know where i want a sample 1020 00:37:00,870 --> 00:36:57,440 i want the instrument to touch it 1021 00:37:01,750 --> 00:37:00,880 um interrogate it um i i think that that 1022 00:37:03,910 --> 00:37:01,760 you know 1023 00:37:05,270 --> 00:37:03,920 remote sensing is gonna in terms of 1024 00:37:07,030 --> 00:37:05,280 light detection 1025 00:37:08,630 --> 00:37:07,040 you know eventually will be particularly 1026 00:37:09,430 --> 00:37:08,640 relevant for 1027 00:37:11,510 --> 00:37:09,440 um 1028 00:37:14,069 --> 00:37:11,520 for exoplanets and looking at 1029 00:37:15,589 --> 00:37:14,079 atmospheres and trying to understand um 1030 00:37:17,670 --> 00:37:15,599 you know are these 1031 00:37:19,910 --> 00:37:17,680 is do they have atmospheres that are 1032 00:37:21,589 --> 00:37:19,920 indicative processes that might suggest 1033 00:37:25,109 --> 00:37:21,599 the presence of life 1034 00:37:27,270 --> 00:37:26,069 you know 1035 00:37:29,270 --> 00:37:27,280 remotely 1036 00:37:31,270 --> 00:37:29,280 in terms of mars just our ability to 1037 00:37:34,069 --> 00:37:31,280 understand the whole planet and really 1038 00:37:37,670 --> 00:37:34,079 when we landed there in 1976 we saw this 1039 00:37:40,390 --> 00:37:37,680 landscape of of just you know 1040 00:37:41,990 --> 00:37:40,400 red dust everywhere and for a long time 1041 00:37:43,829 --> 00:37:42,000 people thought well that's the planet 1042 00:37:46,310 --> 00:37:43,839 but really it was the remote sensing 1043 00:37:48,630 --> 00:37:46,320 that really before we even got back to 1044 00:37:50,390 --> 00:37:48,640 the planet again you know 20 more than 1045 00:37:52,310 --> 00:37:50,400 20 years later 1046 00:37:54,069 --> 00:37:52,320 really really gave us an in-depth 1047 00:37:56,630 --> 00:37:54,079 understanding of the habitability the 1048 00:37:59,190 --> 00:37:56,640 potential for life so understanding 1049 00:38:00,950 --> 00:37:59,200 those mineral assemblages the geology is 1050 00:38:02,630 --> 00:38:00,960 really critical and that's all achieved 1051 00:38:03,990 --> 00:38:02,640 through remote sensing 1052 00:38:06,310 --> 00:38:04,000 not all of them 1053 00:38:07,589 --> 00:38:06,320 and i'll just add to that richard you 1054 00:38:10,390 --> 00:38:07,599 know what you're 1055 00:38:12,790 --> 00:38:10,400 you're you're referring to also just the 1056 00:38:15,190 --> 00:38:12,800 the connection i think between what you 1057 00:38:17,990 --> 00:38:15,200 can learn remote sensing on a planetary 1058 00:38:20,150 --> 00:38:18,000 global scale particularly if you're if 1059 00:38:23,270 --> 00:38:20,160 you have an orbiter which is like the 1060 00:38:27,270 --> 00:38:23,280 dream of many geologists is to have 1061 00:38:29,670 --> 00:38:27,280 global mapping um of of an entire planet 1062 00:38:31,829 --> 00:38:29,680 at sufficient resolution so that you can 1063 00:38:33,510 --> 00:38:31,839 you know just decipher some of the 1064 00:38:36,390 --> 00:38:33,520 signatures on the surface and trace it 1065 00:38:38,870 --> 00:38:36,400 back to geological processes that that 1066 00:38:42,150 --> 00:38:38,880 we might already know and then that 1067 00:38:45,109 --> 00:38:42,160 gives you such amazing context for 1068 00:38:48,470 --> 00:38:45,119 in-situ exploration because oftentimes 1069 00:38:50,950 --> 00:38:48,480 you're picking one place or one region 1070 00:38:54,150 --> 00:38:50,960 of the surface of the surface of a 1071 00:38:56,390 --> 00:38:54,160 planet and um you know 1072 00:38:59,270 --> 00:38:56,400 there is surface mobility but but often 1073 00:39:01,990 --> 00:38:59,280 you nee when you want to understand how 1074 00:39:04,630 --> 00:39:02,000 this um this particular region or 1075 00:39:07,430 --> 00:39:04,640 landing site um you know relates to the 1076 00:39:08,950 --> 00:39:07,440 planetary and uh processes at large you 1077 00:39:11,589 --> 00:39:08,960 need that global understanding so 1078 00:39:14,390 --> 00:39:11,599 there's absolutely um you know 1079 00:39:16,470 --> 00:39:14,400 importance in remote sensing uh 1080 00:39:18,150 --> 00:39:16,480 not only for global mapping but just 1081 00:39:21,030 --> 00:39:18,160 global you know more 1082 00:39:21,910 --> 00:39:21,040 larger context you don't throw away any 1083 00:39:25,430 --> 00:39:21,920 of your 1084 00:39:27,990 --> 00:39:25,440 coming off the surface at you so you can 1085 00:39:31,109 --> 00:39:28,000 tell different things about the surface 1086 00:39:35,109 --> 00:39:31,119 um whether it's you know uh mineralogy 1087 00:39:38,150 --> 00:39:35,119 or um or uh um you know for water or 1088 00:39:42,790 --> 00:39:38,160 potentially hydrated minerals 1089 00:39:45,109 --> 00:39:42,800 all these things can be uh 1090 00:39:47,430 --> 00:39:45,119 who are experts out there um but but you 1091 00:39:49,750 --> 00:39:47,440 can learn quite a lot um within the 1092 00:39:52,150 --> 00:39:49,760 resolution limitations of course um but 1093 00:39:53,430 --> 00:39:52,160 by remote sensing um 1094 00:39:54,230 --> 00:39:53,440 we're we're 1095 00:39:56,150 --> 00:39:54,240 uh 1096 00:39:58,630 --> 00:39:56,160 not to talk too much about da vinci but 1097 00:40:01,430 --> 00:39:58,640 we're um you know we have two elements 1098 00:40:04,150 --> 00:40:01,440 to our mission one we'll do a couple of 1099 00:40:06,870 --> 00:40:04,160 flybys of the planet 1100 00:40:10,150 --> 00:40:06,880 um and uh with some remote sensing 1101 00:40:11,910 --> 00:40:10,160 capabilities um and look at the clouds 1102 00:40:13,910 --> 00:40:11,920 look at cloud dynamics look at cloud 1103 00:40:15,349 --> 00:40:13,920 chemistry uh look at the night side of 1104 00:40:16,870 --> 00:40:15,359 the planet see if we can peer through 1105 00:40:19,030 --> 00:40:16,880 the clouds in certain wavelengths and 1106 00:40:20,950 --> 00:40:19,040 tell something about the um the rock 1107 00:40:23,349 --> 00:40:20,960 types on the surface and then connect 1108 00:40:24,870 --> 00:40:23,359 that to our descent imagery as our probe 1109 00:40:27,750 --> 00:40:24,880 goes through the clouds i mean the 1110 00:40:30,390 --> 00:40:27,760 clouds are hard on venus and uh and so 1111 00:40:32,710 --> 00:40:30,400 um remote sensing certainly has uh 1112 00:40:33,910 --> 00:40:32,720 provides context um you know but it's 1113 00:40:36,309 --> 00:40:33,920 it's uh 1114 00:40:38,630 --> 00:40:36,319 it's a it's a compliment to uh to 1115 00:40:39,990 --> 00:40:38,640 in-situ investigation 1116 00:40:41,589 --> 00:40:40,000 i love that 1117 00:40:43,589 --> 00:40:41,599 scale of different ways of looking but 1118 00:40:46,069 --> 00:40:43,599 also the complementation you know the 1119 00:40:47,430 --> 00:40:46,079 nature of these orbiters and landers and 1120 00:40:49,430 --> 00:40:47,440 things like that i know with europa 1121 00:40:50,550 --> 00:40:49,440 clipper for instance at first you know 1122 00:40:52,710 --> 00:40:50,560 some of us thought we would get like 1123 00:40:54,790 --> 00:40:52,720 little micro landers or little things 1124 00:40:56,550 --> 00:40:54,800 that would drop off the spacecraft that 1125 00:40:58,309 --> 00:40:56,560 didn't happen in the end unfortunately i 1126 00:40:59,670 --> 00:40:58,319 really wish it had but maybe in the 1127 00:41:01,270 --> 00:40:59,680 future we'll see more of these 1128 00:41:03,510 --> 00:41:01,280 complementary missions that have the 1129 00:41:05,589 --> 00:41:03,520 orbiter lander maybe even rover all as 1130 00:41:06,870 --> 00:41:05,599 you know one package together 1131 00:41:09,030 --> 00:41:06,880 we do have one question that came in 1132 00:41:10,390 --> 00:41:09,040 from a new eraser 1133 00:41:12,150 --> 00:41:10,400 i apologize and nuke that's not the 1134 00:41:13,910 --> 00:41:12,160 correct pronunciation 1135 00:41:15,190 --> 00:41:13,920 a nuke has asked 1136 00:41:17,190 --> 00:41:15,200 what would you say is the main 1137 00:41:19,829 --> 00:41:17,200 limitation for scientific instruments on 1138 00:41:21,829 --> 00:41:19,839 mars rovers is it power availability 1139 00:41:24,069 --> 00:41:21,839 size the weight robustness of 1140 00:41:25,430 --> 00:41:24,079 instruments for space missions um and i 1141 00:41:26,710 --> 00:41:25,440 guess stephanie i'll start with you what 1142 00:41:29,109 --> 00:41:26,720 do you think are the main limitations 1143 00:41:33,109 --> 00:41:29,119 for for our scientific instruments 1144 00:41:34,470 --> 00:41:33,119 um yeah mars well so mars in particular 1145 00:41:36,309 --> 00:41:34,480 is hard 1146 00:41:38,710 --> 00:41:36,319 um from the perspective that there's 1147 00:41:39,829 --> 00:41:38,720 enough atmosphere to try to kill you on 1148 00:41:42,630 --> 00:41:39,839 the way down 1149 00:41:43,910 --> 00:41:42,640 but not enough um to really make it easy 1150 00:41:45,190 --> 00:41:43,920 on you like venus is easy because 1151 00:41:47,349 --> 00:41:45,200 there's a huge amount of atmosphere you 1152 00:41:50,150 --> 00:41:47,359 need a tiny parachute for only part of 1153 00:41:52,390 --> 00:41:50,160 your descent right but um but for mars 1154 00:41:54,470 --> 00:41:52,400 the the the atmosphere is in this zone 1155 00:41:56,470 --> 00:41:54,480 where you need huge parachutes and you 1156 00:41:59,510 --> 00:41:56,480 also need like you know oftentimes some 1157 00:42:02,230 --> 00:41:59,520 other uh mechanism to help you land um 1158 00:42:03,750 --> 00:42:02,240 safely and so what that translates to is 1159 00:42:07,670 --> 00:42:03,760 of course limitations on how much you 1160 00:42:12,069 --> 00:42:07,680 can land um in terms of mass and uh 1161 00:42:14,710 --> 00:42:12,079 um and capability and so i it um i mean 1162 00:42:17,270 --> 00:42:14,720 obviously to fit inside a rocket fairing 1163 00:42:18,390 --> 00:42:17,280 you you have some limitations to your 1164 00:42:22,950 --> 00:42:18,400 volume 1165 00:42:24,230 --> 00:42:22,960 between how many different capabilities 1166 00:42:25,829 --> 00:42:24,240 you can send and how big those 1167 00:42:29,270 --> 00:42:25,839 capabilities are 1168 00:42:31,030 --> 00:42:29,280 um and so so you so you somehow just 1169 00:42:32,950 --> 00:42:31,040 find this optimum 1170 00:42:34,390 --> 00:42:32,960 for the particular opportunity that you 1171 00:42:36,710 --> 00:42:34,400 have that 1172 00:42:40,630 --> 00:42:36,720 you know that fits within your fairing 1173 00:42:43,109 --> 00:42:40,640 that can be landed with uh safely onto 1174 00:42:46,470 --> 00:42:43,119 the surface of the planet if that's your 1175 00:42:49,910 --> 00:42:46,480 mission goal um and uh and it has enough 1176 00:42:52,630 --> 00:42:49,920 breadth to be able to um you know to put 1177 00:42:54,069 --> 00:42:52,640 your core discoveries into context um in 1178 00:42:55,829 --> 00:42:54,079 that environment 1179 00:42:57,910 --> 00:42:55,839 i don't know if that helps it's very 1180 00:42:59,030 --> 00:42:57,920 very helpful uh next we have a second 1181 00:43:01,589 --> 00:42:59,040 question from a nuke that i think i'm 1182 00:43:03,430 --> 00:43:01,599 going to answer first so a nuke says i 1183 00:43:05,589 --> 00:43:03,440 use raman spectroscopy in my research 1184 00:43:06,710 --> 00:43:05,599 i'm a big fan what are the limitations 1185 00:43:08,470 --> 00:43:06,720 that stop us from putting a very 1186 00:43:11,030 --> 00:43:08,480 sensitive raman spectroscope on mars and 1187 00:43:13,190 --> 00:43:11,040 looking for organics um a nuke we have a 1188 00:43:15,349 --> 00:43:13,200 raman spectroscope on mars and it can 1189 00:43:17,190 --> 00:43:15,359 look for organics um own perseverance 1190 00:43:18,950 --> 00:43:17,200 the sherlock instrument uh i also use 1191 00:43:21,589 --> 00:43:18,960 ramon spectroscopy in my graduate 1192 00:43:23,910 --> 00:43:21,599 research uh and and super excited for 1193 00:43:26,150 --> 00:43:23,920 perseverance and for sherlock 1194 00:43:27,670 --> 00:43:26,160 and so richard maybe for you um what are 1195 00:43:29,589 --> 00:43:27,680 the limitations we've had in getting 1196 00:43:31,349 --> 00:43:29,599 some of these more these newer kind of 1197 00:43:34,630 --> 00:43:31,359 uh instrumental approaches onto some of 1198 00:43:35,990 --> 00:43:34,640 our rovers and our spacecraft 1199 00:43:39,030 --> 00:43:36,000 well i think 1200 00:43:41,670 --> 00:43:39,040 you know you take something like 1201 00:43:43,750 --> 00:43:41,680 we are bringing new technologies and new 1202 00:43:45,990 --> 00:43:43,760 approaches on these rovers 1203 00:43:48,630 --> 00:43:46,000 um so i don't think it's it's an issue 1204 00:43:50,870 --> 00:43:48,640 of the technologies but i agree with 1205 00:43:52,870 --> 00:43:50,880 with stephanie every mission has 1206 00:43:56,870 --> 00:43:52,880 multiple objectives 1207 00:43:59,349 --> 00:43:56,880 you have to have multiple instruments 1208 00:44:02,309 --> 00:43:59,359 multiple instruments types that need to 1209 00:44:04,710 --> 00:44:02,319 share resources and so particularly on a 1210 00:44:07,190 --> 00:44:04,720 rover you have all sorts of resource 1211 00:44:09,349 --> 00:44:07,200 limitations so i think that that that 1212 00:44:12,069 --> 00:44:09,359 um you know 1213 00:44:14,790 --> 00:44:12,079 each each time we go the rose rovers get 1214 00:44:18,390 --> 00:44:14,800 bigger and more capable um but still i 1215 00:44:20,390 --> 00:44:18,400 think that that's a a primary limitation 1216 00:44:21,430 --> 00:44:20,400 we try to do a number of different 1217 00:44:23,190 --> 00:44:21,440 things 1218 00:44:26,790 --> 00:44:23,200 and we need a number of different tools 1219 00:44:30,069 --> 00:44:26,800 to do that um and so that that you know 1220 00:44:33,190 --> 00:44:30,079 spreads resources around 1221 00:44:37,910 --> 00:44:33,200 very good um questions john rose told 1222 00:44:42,230 --> 00:44:39,430 i imagine john's thinking of maybe 1223 00:44:44,470 --> 00:44:42,240 metabolisms that rely on producing and 1224 00:44:47,349 --> 00:44:44,480 probably more more likely consuming 1225 00:44:48,390 --> 00:44:47,359 methane so methanotrophs perhaps um so 1226 00:44:50,390 --> 00:44:48,400 john wants to know what kinds of 1227 00:44:52,390 --> 00:44:50,400 scientific instruments you think 1228 00:44:54,790 --> 00:44:52,400 we would need to detect to detect these 1229 00:45:02,230 --> 00:44:54,800 life forms that could be in a place like 1230 00:45:05,109 --> 00:45:03,190 that's a 1231 00:45:06,950 --> 00:45:05,119 well we're not going to solve this here 1232 00:45:09,109 --> 00:45:06,960 but um 1233 00:45:11,109 --> 00:45:09,119 uh but i think it's a it's a valid 1234 00:45:12,630 --> 00:45:11,119 question i mean i think that we're um 1235 00:45:13,829 --> 00:45:12,640 and i'm going to hand it over to richard 1236 00:45:15,910 --> 00:45:13,839 in a second there are two things i want 1237 00:45:17,510 --> 00:45:15,920 to say first thing is that we're still 1238 00:45:19,670 --> 00:45:17,520 in the um 1239 00:45:21,750 --> 00:45:19,680 uh um 1240 00:45:23,589 --> 00:45:21,760 at the level of understanding at titan 1241 00:45:25,190 --> 00:45:23,599 that we're still asking basic questions 1242 00:45:27,750 --> 00:45:25,200 about what the 1243 00:45:29,430 --> 00:45:27,760 you know the resources are for any life 1244 00:45:30,790 --> 00:45:29,440 form there we know that it's cold there 1245 00:45:33,109 --> 00:45:30,800 we know that there's liquid there that's 1246 00:45:36,470 --> 00:45:33,119 great we know there's ice water ice 1247 00:45:38,069 --> 00:45:36,480 there that's also cool 1248 00:45:40,630 --> 00:45:38,079 and we know that there's a really rich 1249 00:45:43,109 --> 00:45:40,640 atmosphere that is a laboratory for 1250 00:45:45,910 --> 00:45:43,119 organic chemistry which is really cool 1251 00:45:48,390 --> 00:45:45,920 and definitely prebiotically 1252 00:45:51,109 --> 00:45:48,400 important if not biologically active 1253 00:45:52,390 --> 00:45:51,119 right now um but with with dragonfly and 1254 00:45:53,990 --> 00:45:52,400 i'm not on the dragonfly mission so 1255 00:45:54,790 --> 00:45:54,000 forgive me if i get anything wrong um 1256 00:45:56,710 --> 00:45:54,800 but 1257 00:45:58,870 --> 00:45:56,720 with dragonfly we're going to ask those 1258 00:46:01,510 --> 00:45:58,880 really foundational questions about what 1259 00:46:02,230 --> 00:46:01,520 the current chemistry is what the cycles 1260 00:46:03,829 --> 00:46:02,240 are 1261 00:46:06,470 --> 00:46:03,839 how the surface expresses those 1262 00:46:08,069 --> 00:46:06,480 different cycles what variability there 1263 00:46:10,710 --> 00:46:08,079 is across the surface for those who 1264 00:46:12,950 --> 00:46:10,720 don't know dragonfly is a quadcopter 1265 00:46:14,550 --> 00:46:12,960 with aerial mobility that will land 1266 00:46:17,190 --> 00:46:14,560 repeatedly 1267 00:46:19,990 --> 00:46:17,200 in in different regions of 1268 00:46:23,030 --> 00:46:20,000 saturn's moon titan and and take 1269 00:46:25,670 --> 00:46:23,040 analyses take in samples and analyze 1270 00:46:27,510 --> 00:46:25,680 those samples and look at variability in 1271 00:46:29,510 --> 00:46:27,520 the chemistry of the surface environment 1272 00:46:31,349 --> 00:46:29,520 and atmosphere near surface atmosphere 1273 00:46:32,630 --> 00:46:31,359 of titan um 1274 00:46:34,950 --> 00:46:32,640 through the course of that mission so 1275 00:46:37,190 --> 00:46:34,960 that's really exciting because it's like 1276 00:46:38,470 --> 00:46:37,200 um we're on the verge of understanding 1277 00:46:41,109 --> 00:46:38,480 an incredible 1278 00:46:43,190 --> 00:46:41,119 amount about titan where we can then 1279 00:46:44,230 --> 00:46:43,200 kind of engage 1280 00:46:45,750 --> 00:46:44,240 our best 1281 00:46:48,150 --> 00:46:45,760 thinkers on 1282 00:46:50,790 --> 00:46:48,160 the fundamentals of biology 1283 00:46:53,670 --> 00:46:50,800 and um and start to ask questions about 1284 00:46:55,910 --> 00:46:53,680 what a metabolism would look like right 1285 00:46:58,309 --> 00:46:55,920 but i think and and let me say that 1286 00:47:02,069 --> 00:46:58,319 dragonfly that instrument suite the 1287 00:47:04,870 --> 00:47:02,079 payload suite is um is capable of making 1288 00:47:06,790 --> 00:47:04,880 really broad analytical measurements 1289 00:47:08,390 --> 00:47:06,800 that can be interpreted and debated 1290 00:47:11,270 --> 00:47:08,400 probably right 1291 00:47:13,990 --> 00:47:11,280 about what they mean um so that that 1292 00:47:16,790 --> 00:47:14,000 mission is a good example of where you 1293 00:47:18,470 --> 00:47:16,800 can incorporate instrumentation you can 1294 00:47:21,109 --> 00:47:18,480 you know include instrumentation in your 1295 00:47:23,829 --> 00:47:21,119 payload that's capable of really broad 1296 00:47:26,870 --> 00:47:23,839 scientific inquiry and prepared to 1297 00:47:30,069 --> 00:47:26,880 discover new things and that is the one 1298 00:47:31,829 --> 00:47:30,079 of the really really exciting things 1299 00:47:33,910 --> 00:47:31,839 very cool and you know drones are so hot 1300 00:47:36,549 --> 00:47:33,920 right now um but dragonfly is going 1301 00:47:38,710 --> 00:47:36,559 someplace super cold uh the surface 1302 00:47:41,589 --> 00:47:38,720 titan is very cold perhaps too cold for 1303 00:47:42,950 --> 00:47:41,599 for metabolisms at the surface and so so 1304 00:47:45,510 --> 00:47:42,960 richard um if you can answer the 1305 00:47:46,790 --> 00:47:45,520 question as well but also i'd ask uh 1306 00:47:49,829 --> 00:47:46,800 what would we have to take to get into 1307 00:47:52,230 --> 00:47:49,839 the subsurface of titan as well 1308 00:47:54,710 --> 00:47:52,240 um well the first part of the question 1309 00:47:56,870 --> 00:47:54,720 i'll i again i agree with stephanie 1310 00:47:59,510 --> 00:47:56,880 completely you know we can look back to 1311 00:48:01,190 --> 00:47:59,520 viking and the first mission to viking 1312 00:48:03,990 --> 00:48:01,200 they were it's going to be light 1313 00:48:05,589 --> 00:48:04,000 detection and three of their four 1314 00:48:06,790 --> 00:48:05,599 primary instruments were all about 1315 00:48:08,470 --> 00:48:06,800 trying to 1316 00:48:10,390 --> 00:48:08,480 dig up a little bit of soil and trying 1317 00:48:12,549 --> 00:48:10,400 to grow microbes in it 1318 00:48:14,309 --> 00:48:12,559 um and so what did we miss in that 1319 00:48:16,549 --> 00:48:14,319 mission well we missed the opportunity 1320 00:48:19,349 --> 00:48:16,559 to get some of the real fundamental 1321 00:48:21,270 --> 00:48:19,359 understanding of the environment that we 1322 00:48:23,349 --> 00:48:21,280 then did with follow-on missions we 1323 00:48:25,030 --> 00:48:23,359 really changed our strategy as stephanie 1324 00:48:27,910 --> 00:48:25,040 has already mentioned you know 1325 00:48:31,829 --> 00:48:27,920 step-by-step building on your knowledge 1326 00:48:34,549 --> 00:48:31,839 titan is a incredibly alien um 1327 00:48:37,829 --> 00:48:34,559 environment that we really don't know 1328 00:48:39,910 --> 00:48:37,839 much about at all and so the strategy 1329 00:48:42,950 --> 00:48:39,920 that's being used as stephanie pointed 1330 00:48:45,349 --> 00:48:42,960 out is to really start out funding 1331 00:48:48,230 --> 00:48:45,359 increasing our fundamental understanding 1332 00:48:51,030 --> 00:48:48,240 of that environment and from there we 1333 00:48:53,030 --> 00:48:51,040 can start developing hypotheses about 1334 00:49:00,829 --> 00:48:53,040 the potential for life and how that 1335 00:49:04,390 --> 00:49:01,990 um it's something new and dear to my 1336 00:49:06,870 --> 00:49:04,400 heart but um i'll let you choose if you 1337 00:49:09,190 --> 00:49:06,880 want to answer this uh william creamer 1338 00:49:11,510 --> 00:49:09,200 on youtube has asked um where we have 1339 00:49:13,190 --> 00:49:11,520 experiments that can grab samples um you 1340 00:49:16,470 --> 00:49:13,200 know in situ so we're grabbing up some 1341 00:49:18,309 --> 00:49:16,480 regolith that might contain e.t life 1342 00:49:21,349 --> 00:49:18,319 um is there a consideration of the 1343 00:49:24,230 --> 00:49:21,359 bioethical consequences of potentially 1344 00:49:26,390 --> 00:49:24,240 harming any life in the sample 1345 00:49:28,470 --> 00:49:26,400 and so i'll start um since i'm currently 1346 00:49:31,430 --> 00:49:28,480 working on a collaboration with the 1347 00:49:33,349 --> 00:49:31,440 artist lucia monge she and i are going 1348 00:49:35,430 --> 00:49:33,359 to be growing ornamental plants in in 1349 00:49:37,670 --> 00:49:35,440 martian regal and marshall conditions 1350 00:49:40,710 --> 00:49:37,680 specifically on martian time with the 1351 00:49:42,950 --> 00:49:40,720 extra 40 minutes of day length 1352 00:49:44,630 --> 00:49:42,960 however we're also thinking about not 1353 00:49:46,790 --> 00:49:44,640 just the the impacts to the plants but 1354 00:49:48,710 --> 00:49:46,800 also the impacts to the humans as well 1355 00:49:51,430 --> 00:49:48,720 as the ethics uh the ethical 1356 00:49:53,430 --> 00:49:51,440 consequences of putting other organisms 1357 00:49:55,430 --> 00:49:53,440 into these conditions and so this is 1358 00:49:57,190 --> 00:49:55,440 kind of important for my own work in 1359 00:49:59,750 --> 00:49:57,200 considering you know how do we treat 1360 00:50:01,829 --> 00:49:59,760 other life out there um so i wonder for 1361 00:50:03,829 --> 00:50:01,839 either of you in your own conversations 1362 00:50:05,990 --> 00:50:03,839 um perhaps in the workshop have anything 1363 00:50:09,349 --> 00:50:06,000 around this kind of theme of bioethics 1364 00:50:13,349 --> 00:50:10,549 well 1365 00:50:14,710 --> 00:50:13,359 so i i would say that that that part of 1366 00:50:15,589 --> 00:50:14,720 that is 1367 00:50:18,549 --> 00:50:15,599 you know 1368 00:50:20,309 --> 00:50:18,559 falls within a broader discussion that 1369 00:50:22,790 --> 00:50:20,319 we have all the time about forward 1370 00:50:24,309 --> 00:50:22,800 contamination of another planet 1371 00:50:29,510 --> 00:50:24,319 and that has 1372 00:50:34,069 --> 00:50:31,510 so i would say that the community 1373 00:50:35,990 --> 00:50:34,079 or or you know planetary sciences it is 1374 00:50:37,190 --> 00:50:36,000 something that is thought about and is 1375 00:50:40,790 --> 00:50:37,200 considered 1376 00:50:43,349 --> 00:50:40,800 um and and our approaches to exploration 1377 00:50:44,950 --> 00:50:43,359 are you know also take that into account 1378 00:50:47,910 --> 00:50:44,960 in terms of planetary protection 1379 00:50:50,309 --> 00:50:47,920 requirements or you know ability to you 1380 00:50:53,109 --> 00:50:50,319 know contaminate the planet and also to 1381 00:50:55,109 --> 00:50:53,119 contaminate our own science 1382 00:50:56,549 --> 00:50:55,119 oh it's a very true 1383 00:50:57,910 --> 00:50:56,559 actually we have another question from 1384 00:51:00,309 --> 00:50:57,920 the nuke again he's asking some really 1385 00:51:03,109 --> 00:51:00,319 good ones here uh a nuke uh wants to 1386 00:51:06,230 --> 00:51:03,119 know with the possible contamination 1387 00:51:09,109 --> 00:51:06,240 of mars from human habitation um how 1388 00:51:12,470 --> 00:51:09,119 might that affect our search for current 1389 00:51:15,750 --> 00:51:12,480 or or past life on mars 1390 00:51:18,870 --> 00:51:17,190 because i 1391 00:51:20,630 --> 00:51:18,880 talked about this quite a bit 1392 00:51:22,870 --> 00:51:20,640 and and you know 1393 00:51:24,309 --> 00:51:22,880 so there's two parts of or there's you 1394 00:51:27,190 --> 00:51:24,319 know it's sort of a continuum right 1395 00:51:29,190 --> 00:51:27,200 they'll be the first discovery of life 1396 00:51:30,790 --> 00:51:29,200 um that'll happen sometime hopefully in 1397 00:51:32,790 --> 00:51:30,800 the very near future 1398 00:51:34,710 --> 00:51:32,800 um but we could compare that to say the 1399 00:51:37,349 --> 00:51:34,720 search for exoplanets 1400 00:51:39,349 --> 00:51:37,359 after the first exoplanet was discovered 1401 00:51:41,030 --> 00:51:39,359 that field exploded 1402 00:51:42,870 --> 00:51:41,040 trying to understand 1403 00:51:44,710 --> 00:51:42,880 where they are how many they are what's 1404 00:51:46,390 --> 00:51:44,720 their nature i think with human 1405 00:51:51,109 --> 00:51:46,400 exploration the same thing is going to 1406 00:51:53,589 --> 00:51:51,119 happen um there will be it will increase 1407 00:51:55,990 --> 00:51:53,599 um the effort to search for life by 1408 00:51:58,470 --> 00:51:56,000 orders of magnitude so it's not it's not 1409 00:52:01,589 --> 00:51:58,480 a negative it's actually a positive and 1410 00:52:03,589 --> 00:52:01,599 i would put it in comparison also to the 1411 00:52:04,390 --> 00:52:03,599 research that people do here on earth 1412 00:52:06,870 --> 00:52:04,400 right 1413 00:52:09,109 --> 00:52:06,880 we're constantly out in the field trying 1414 00:52:09,990 --> 00:52:09,119 to understand the origin of life on 1415 00:52:12,630 --> 00:52:10,000 earth 1416 00:52:14,470 --> 00:52:12,640 and the presence of humans well 1417 00:52:16,309 --> 00:52:14,480 no matter how much we pollute we're 1418 00:52:18,069 --> 00:52:16,319 still searching that answer and and 1419 00:52:18,870 --> 00:52:18,079 we're still successful i don't think 1420 00:52:22,069 --> 00:52:18,880 that 1421 00:52:24,470 --> 00:52:22,079 um you know the the the signs of life um 1422 00:52:26,470 --> 00:52:24,480 are vast and diverse and i don't think 1423 00:52:29,349 --> 00:52:26,480 we're going to be confusing 1424 00:52:31,190 --> 00:52:29,359 um say ancient fossil records on mars 1425 00:52:34,309 --> 00:52:31,200 with contemporary contamination that 1426 00:52:37,030 --> 00:52:34,319 come from humans so i see that you know 1427 00:52:39,270 --> 00:52:37,040 the the human exploration part of mars 1428 00:52:40,549 --> 00:52:39,280 really just expands our ability to 1429 00:52:42,630 --> 00:52:40,559 understand 1430 00:52:44,870 --> 00:52:42,640 uh the potential for life on mars and 1431 00:52:46,630 --> 00:52:44,880 its potential distribution so i look 1432 00:52:49,270 --> 00:52:46,640 really forward to it 1433 00:52:51,670 --> 00:52:49,280 and i'll just add a few programs 1434 00:52:54,390 --> 00:52:51,680 um a couple of things 1435 00:52:56,630 --> 00:52:54,400 really excellent answer um but you know 1436 00:52:58,870 --> 00:52:56,640 we're tackling we're tackling similar 1437 00:53:01,349 --> 00:52:58,880 questions already 1438 00:53:03,109 --> 00:53:01,359 um in terms of how do we distinguish 1439 00:53:05,750 --> 00:53:03,119 between what we've brought 1440 00:53:07,750 --> 00:53:05,760 and um and what's you know 1441 00:53:10,470 --> 00:53:07,760 indigenous to the sample or to the 1442 00:53:12,230 --> 00:53:10,480 environment and so um you know 1443 00:53:14,950 --> 00:53:12,240 so far we've tackled that most 1444 00:53:17,670 --> 00:53:14,960 explicitly for chemical signatures right 1445 00:53:20,069 --> 00:53:17,680 um so we um we 1446 00:53:22,950 --> 00:53:20,079 typically missions exercise very 1447 00:53:25,910 --> 00:53:22,960 rigorous contamination control 1448 00:53:28,870 --> 00:53:25,920 plans to um to document what you're 1449 00:53:32,069 --> 00:53:28,880 sending and to understand how 1450 00:53:34,549 --> 00:53:32,079 those signatures might be expressed by 1451 00:53:37,829 --> 00:53:34,559 um in situ you know analyses once you 1452 00:53:40,069 --> 00:53:37,839 get to a place the the other analogy is 1453 00:53:43,589 --> 00:53:40,079 you know looking at uh 1454 00:53:46,950 --> 00:53:43,599 analyzing meteorites for prebiotic 1455 00:53:49,510 --> 00:53:46,960 compounds like nucleobase amino acid 1456 00:53:51,430 --> 00:53:49,520 oxalic acids i mean routinely routinely 1457 00:53:54,470 --> 00:53:51,440 it takes a lot of effort but we've come 1458 00:53:55,990 --> 00:53:54,480 up with a protocol for for establishing 1459 00:53:58,549 --> 00:53:56,000 which of those amino acids are most 1460 00:54:01,589 --> 00:53:58,559 likely to have originated beyond earth 1461 00:54:04,069 --> 00:54:01,599 in prebiotic chemical pathways on on 1462 00:54:05,829 --> 00:54:04,079 these you know primitive bodies and 1463 00:54:07,910 --> 00:54:05,839 which are contamination from earth and 1464 00:54:10,790 --> 00:54:07,920 that comes from like you know just the 1465 00:54:13,270 --> 00:54:10,800 prevalence of those amino acids in life 1466 00:54:15,670 --> 00:54:13,280 on earth versus you know what we're um 1467 00:54:18,230 --> 00:54:15,680 what are very convincingly outside of 1468 00:54:20,150 --> 00:54:18,240 the typical regime of life that you 1469 00:54:22,150 --> 00:54:20,160 would see 1470 00:54:25,190 --> 00:54:22,160 terrestrially so i think that we have a 1471 00:54:26,790 --> 00:54:25,200 lot of great thinking to build upon 1472 00:54:28,870 --> 00:54:26,800 to try to tackle some of these 1473 00:54:30,150 --> 00:54:28,880 challenges i mean 1474 00:54:32,470 --> 00:54:30,160 you know i think 1475 00:54:34,630 --> 00:54:32,480 preparation is good and folding in some 1476 00:54:36,789 --> 00:54:34,640 of these concerns into 1477 00:54:39,270 --> 00:54:36,799 plans not only for robotic but for 1478 00:54:41,829 --> 00:54:39,280 future human missions is important and i 1479 00:54:43,829 --> 00:54:41,839 know that thinking is going on um but 1480 00:54:46,150 --> 00:54:43,839 also you know we have good strategies 1481 00:54:48,309 --> 00:54:46,160 for um for being able to differentiate 1482 00:54:50,630 --> 00:54:48,319 between the origin of signals 1483 00:54:51,829 --> 00:54:50,640 that's fantastic um so many important 1484 00:54:53,990 --> 00:54:51,839 things there and i'm going to switch the 1485 00:54:55,589 --> 00:54:54,000 gears a little bit more here again so we 1486 00:54:57,829 --> 00:54:55,599 we switch to like philosophy and 1487 00:54:59,990 --> 00:54:57,839 bioethics um our next question is more 1488 00:55:02,309 --> 00:55:00,000 in the norm of space law and comes from 1489 00:55:04,870 --> 00:55:02,319 adam robinson on youtube 1490 00:55:07,430 --> 00:55:04,880 and so we'll see how much you wish to 1491 00:55:08,950 --> 00:55:07,440 answer this question um adam kind of 1492 00:55:11,510 --> 00:55:08,960 wants to know 1493 00:55:14,630 --> 00:55:11,520 should we create laws or policy 1494 00:55:16,470 --> 00:55:14,640 um to control where private companies um 1495 00:55:17,910 --> 00:55:16,480 and i would actually add any government 1496 00:55:20,309 --> 00:55:17,920 agency as well 1497 00:55:22,549 --> 00:55:20,319 from going to certain areas perhaps on 1498 00:55:24,309 --> 00:55:22,559 mars or another world that we've deemed 1499 00:55:26,630 --> 00:55:24,319 potentially habitable or that could be a 1500 00:55:28,150 --> 00:55:26,640 good place to find signs of past or 1501 00:55:30,390 --> 00:55:28,160 present life 1502 00:55:32,470 --> 00:55:30,400 this kind of reminds me of the concept 1503 00:55:34,789 --> 00:55:32,480 of planetary parks for instance should 1504 00:55:36,870 --> 00:55:34,799 we have preserved areas of some of these 1505 00:55:38,870 --> 00:55:36,880 worlds where for instance we don't send 1506 00:55:40,230 --> 00:55:38,880 a rover because it might just be that 1507 00:55:42,950 --> 00:55:40,240 nice and pristine and we don't want to 1508 00:55:44,950 --> 00:55:42,960 ruin anything um stephanie what do you 1509 00:55:47,670 --> 00:55:44,960 think about that well i'm a big fan of 1510 00:55:49,510 --> 00:55:47,680 national parks on earth so 1511 00:55:51,910 --> 00:55:49,520 yes no 1512 00:55:54,309 --> 00:55:51,920 i don't know that um i it's obviously 1513 00:55:57,750 --> 00:55:54,319 outside of my field but um but i think 1514 00:56:02,390 --> 00:55:57,760 uh you know that there are good examples 1515 00:56:03,510 --> 00:56:02,400 of where um people from different uh um 1516 00:56:07,030 --> 00:56:03,520 you know 1517 00:56:09,829 --> 00:56:07,040 countries have come together and come to 1518 00:56:13,430 --> 00:56:09,839 agreements about how to um 1519 00:56:15,829 --> 00:56:13,440 uh you know rules of exploration and and 1520 00:56:18,549 --> 00:56:15,839 uh and some common um 1521 00:56:20,470 --> 00:56:18,559 values that we have in 1522 00:56:23,270 --> 00:56:20,480 exploring um 1523 00:56:25,750 --> 00:56:23,280 space and um and i think you know the 1524 00:56:28,390 --> 00:56:25,760 future is that there are 1525 00:56:31,670 --> 00:56:28,400 there's a proliferation of 1526 00:56:34,549 --> 00:56:31,680 entities that are capable of pushing 1527 00:56:36,789 --> 00:56:34,559 um exploration even further and so we 1528 00:56:37,670 --> 00:56:36,799 should i think we should acknowledge it 1529 00:56:39,030 --> 00:56:37,680 and 1530 00:56:41,589 --> 00:56:39,040 bring together 1531 00:56:44,150 --> 00:56:41,599 uh um you know all interested parties 1532 00:56:46,549 --> 00:56:44,160 into those discussions but i'm sorry i'm 1533 00:56:48,470 --> 00:56:46,559 like really out on a limb 1534 00:56:49,750 --> 00:56:48,480 i love that answer 1535 00:56:51,829 --> 00:56:49,760 and i guess so we actually are coming 1536 00:56:53,430 --> 00:56:51,839 down to the top of the hour and i'm 1537 00:56:54,710 --> 00:56:53,440 going to be a little selfish here and 1538 00:56:55,829 --> 00:56:54,720 ask you one more question and i think 1539 00:56:58,230 --> 00:56:55,839 it's kind of fun 1540 00:56:59,750 --> 00:56:58,240 um so for myself i was inspired at five 1541 00:57:02,390 --> 00:56:59,760 years old to become a scientist by 1542 00:57:03,990 --> 00:57:02,400 watching an an 80s movie that had some 1543 00:57:06,069 --> 00:57:04,000 rock and roll in it and talked about 1544 00:57:07,670 --> 00:57:06,079 mathematics and you know with my life i 1545 00:57:09,990 --> 00:57:07,680 was inspired by things like star trek 1546 00:57:11,670 --> 00:57:10,000 and star wars um i wonder for both of 1547 00:57:14,549 --> 00:57:11,680 you is there anything in like science 1548 00:57:16,470 --> 00:57:14,559 fiction or literature film comic books 1549 00:57:18,789 --> 00:57:16,480 or novels things that you know that 1550 00:57:21,670 --> 00:57:18,799 others have created maybe even art that 1551 00:57:23,990 --> 00:57:21,680 has inspired you to pursue these careers 1552 00:57:25,750 --> 00:57:24,000 that you've both taken on in your lives 1553 00:57:27,190 --> 00:57:25,760 and richard i'll start with you is there 1554 00:57:29,190 --> 00:57:27,200 anything that's really inspired you to 1555 00:57:31,430 --> 00:57:29,200 pursue this life 1556 00:57:33,190 --> 00:57:31,440 well i i started my career in science 1557 00:57:35,109 --> 00:57:33,200 education working at the national 1558 00:57:36,870 --> 00:57:35,119 science foundation and i never actually 1559 00:57:39,670 --> 00:57:36,880 thought i'd become a planetary science 1560 00:57:41,910 --> 00:57:39,680 or or an astrobiologist 1561 00:57:43,829 --> 00:57:41,920 and i can also say that i'm not a big 1562 00:57:47,430 --> 00:57:43,839 fan of science fiction 1563 00:57:48,870 --> 00:57:47,440 um but but what i do love is the process 1564 00:57:50,870 --> 00:57:48,880 of discovery 1565 00:57:53,190 --> 00:57:50,880 and if i were gonna read a book it 1566 00:57:54,950 --> 00:57:53,200 actually might be um you know it would 1567 00:57:56,950 --> 00:57:54,960 be a biography 1568 00:57:59,109 --> 00:57:56,960 or it might be a historic something 1569 00:58:01,670 --> 00:57:59,119 about history because the difference 1570 00:58:03,430 --> 00:58:01,680 between science fiction and 1571 00:58:06,150 --> 00:58:03,440 us is we're real 1572 00:58:07,670 --> 00:58:06,160 and what we're doing is very very real 1573 00:58:09,750 --> 00:58:07,680 and and and 1574 00:58:11,589 --> 00:58:09,760 pursuing that and really understanding 1575 00:58:13,910 --> 00:58:11,599 the real challenges 1576 00:58:15,589 --> 00:58:13,920 um i think is really what what makes 1577 00:58:17,990 --> 00:58:15,599 this job great 1578 00:58:19,990 --> 00:58:18,000 that's fantastic how about you 1579 00:58:23,270 --> 00:58:20,000 what's inspired you and your career i'll 1580 00:58:25,910 --> 00:58:23,280 be really quick um so cosmos the 1581 00:58:27,510 --> 00:58:25,920 original cosmo series earl sagan was on 1582 00:58:30,069 --> 00:58:27,520 all the time when i was a kid so 1583 00:58:32,870 --> 00:58:30,079 obviously that played a huge role um i 1584 00:58:35,109 --> 00:58:32,880 also remember being like a tween-ish 1585 00:58:37,349 --> 00:58:35,119 and um and really pushing myself i 1586 00:58:39,109 --> 00:58:37,359 picked up a brief history of time by 1587 00:58:41,349 --> 00:58:39,119 stephen hawking from the bookstore and i 1588 00:58:42,950 --> 00:58:41,359 really pushed myself to um to read it 1589 00:58:45,510 --> 00:58:42,960 even though i wasn't convinced i could 1590 00:58:47,349 --> 00:58:45,520 right um but but that was a huge source 1591 00:58:49,910 --> 00:58:47,359 of information of inspiration not only 1592 00:58:51,990 --> 00:58:49,920 to like inspire my love of you know the 1593 00:58:53,990 --> 00:58:52,000 universe exploring the universe but also 1594 00:58:56,150 --> 00:58:54,000 to build my own confidence that these 1595 00:58:58,309 --> 00:58:56,160 are concepts that are not beyond me and 1596 00:58:59,430 --> 00:58:58,319 you know i could pursue hard science in 1597 00:59:01,750 --> 00:58:59,440 my studies 1598 00:59:04,230 --> 00:59:01,760 well that's wonderful um i'm so happy 1599 00:59:06,309 --> 00:59:04,240 you've joined us for this show today i'm 1600 00:59:08,150 --> 00:59:06,319 so glad you were both inspired to pursue 1601 00:59:10,470 --> 00:59:08,160 these careers and become astrobiologists 1602 00:59:13,430 --> 00:59:10,480 and planetary scientists and help us to 1603 00:59:14,630 --> 00:59:13,440 continue exploring and being curious uh 1604 00:59:16,789 --> 00:59:14,640 the future of the search for life 1605 00:59:18,870 --> 00:59:16,799 workshop is continuing in two more weeks 1606 00:59:20,230 --> 00:59:18,880 from now there's still more to tackle 1607 00:59:22,069 --> 00:59:20,240 and more work for these communities 1608 00:59:24,069 --> 00:59:22,079 you're bringing together uh for our 1609 00:59:25,510 --> 00:59:24,079 audience watching right now at home even 1610 00:59:27,829 --> 00:59:25,520 if you can't take part in the in the 1611 00:59:29,510 --> 00:59:27,839
