1 00:00:05,990 --> 00:00:03,110 all right so what is next for nasa's 2 00:00:07,829 --> 00:00:06,000 mars insight lander we announced last 3 00:00:10,629 --> 00:00:07,839 week that the lander will head into 4 00:00:13,350 --> 00:00:10,639 retirement in just a couple months as 5 00:00:15,910 --> 00:00:13,360 the solar power winds down but until 6 00:00:17,670 --> 00:00:15,920 then insight is still hunting mars 7 00:00:20,630 --> 00:00:17,680 quakes one of its main goals since 8 00:00:23,590 --> 00:00:20,640 landing on the red planet in 2018 9 00:00:25,750 --> 00:00:23,600 and i'm raquel villanueva here at nasa's 10 00:00:28,070 --> 00:00:25,760 jet propulsion laboratory we are going 11 00:00:30,310 --> 00:00:28,080 to give you a behind-the-scenes look at 12 00:00:33,030 --> 00:00:30,320 a really unique place on lab which is 13 00:00:35,110 --> 00:00:33,040 this mars testing area 14 00:00:37,750 --> 00:00:35,120 and we'll also be answering some of your 15 00:00:39,910 --> 00:00:37,760 questions about the insight lander now 16 00:00:43,190 --> 00:00:39,920 we're coming to you live from the in 17 00:00:46,470 --> 00:00:43,200 situ instrument laboratory it's a space 18 00:00:48,630 --> 00:00:46,480 designed like the surfs of mars so 19 00:00:52,229 --> 00:00:48,640 engineers can conduct tests under 20 00:00:54,950 --> 00:00:52,239 similar conditions and behind us that is 21 00:00:57,110 --> 00:00:54,960 foresight it is insights earth twin used 22 00:00:59,430 --> 00:00:57,120 for testing the model is an exact 23 00:01:01,430 --> 00:00:59,440 duplicate of insight minus a few things 24 00:01:03,910 --> 00:01:01,440 that have been removed like the solar 25 00:01:05,509 --> 00:01:03,920 panels but it gets the name foresight 26 00:01:07,990 --> 00:01:05,519 because engineers practice doing 27 00:01:11,190 --> 00:01:08,000 everything the lander will do on mars 28 00:01:13,350 --> 00:01:11,200 here first and we are joined by two 29 00:01:16,630 --> 00:01:13,360 members of the insight team 30 00:01:18,710 --> 00:01:16,640 testbed lead renee mishra and project 31 00:01:20,469 --> 00:01:18,720 scientist mark panning they'll be 32 00:01:22,310 --> 00:01:20,479 answering some of your questions about 33 00:01:24,870 --> 00:01:22,320 insight what they've learned since it 34 00:01:26,710 --> 00:01:24,880 landed on mars in 2018 and what the 35 00:01:28,710 --> 00:01:26,720 future of the mission looks like now 36 00:01:31,030 --> 00:01:28,720 that we know the power will likely run 37 00:01:32,870 --> 00:01:31,040 out in the next couple months 38 00:01:35,109 --> 00:01:32,880 we want people to get familiar with the 39 00:01:37,749 --> 00:01:35,119 insight lander so could you give people 40 00:01:39,590 --> 00:01:37,759 a quick recap of the mission sure and 41 00:01:41,670 --> 00:01:39,600 it's um fortunately it's much easier to 42 00:01:45,670 --> 00:01:41,680 fix things on earth than on mars 43 00:01:47,749 --> 00:01:45,680 um so uh basically as i was starting to 44 00:01:49,350 --> 00:01:47,759 say earlier insight's really the first 45 00:01:51,109 --> 00:01:49,360 mission that's been designed to look 46 00:01:52,389 --> 00:01:51,119 inside of mars uh we've had lots of 47 00:01:54,149 --> 00:01:52,399 missions that have looked at the surface 48 00:01:55,670 --> 00:01:54,159 in the atmosphere but insight's really 49 00:01:57,350 --> 00:01:55,680 designed to see what's happening in the 50 00:01:59,670 --> 00:01:57,360 deep interior all the way down to its 51 00:02:01,590 --> 00:01:59,680 core and the main tool we use for that 52 00:02:04,469 --> 00:02:01,600 is looking at mars quakes which are 53 00:02:08,070 --> 00:02:04,479 recorded with a seismometer if you look 54 00:02:09,749 --> 00:02:08,080 to the right this is a model of the the 55 00:02:11,589 --> 00:02:09,759 seismometer and we'll we'll talk more 56 00:02:13,910 --> 00:02:11,599 about that in a bit uh but that's 57 00:02:14,949 --> 00:02:13,920 actually what's used to measure mars 58 00:02:17,350 --> 00:02:14,959 quakes 59 00:02:18,710 --> 00:02:17,360 and we've measured over 1300 of them 60 00:02:20,949 --> 00:02:18,720 through the mission and we've used those 61 00:02:22,710 --> 00:02:20,959 to look at the interior we also have a a 62 00:02:25,510 --> 00:02:22,720 couple other key instruments that are 63 00:02:27,910 --> 00:02:25,520 using other ways of looking inside 64 00:02:30,470 --> 00:02:27,920 by attempting to measure heat flow or by 65 00:02:32,630 --> 00:02:30,480 using radio science to measure really 66 00:02:34,309 --> 00:02:32,640 small wobbles of the planet 67 00:02:36,309 --> 00:02:34,319 great thank you mark and if you're just 68 00:02:38,390 --> 00:02:36,319 tuning in again we are answering some 69 00:02:40,229 --> 00:02:38,400 questions about the mars insight lander 70 00:02:42,309 --> 00:02:40,239 if you have a question use the ask nasa 71 00:02:44,390 --> 00:02:42,319 hashtag or drop in the comments below 72 00:02:47,190 --> 00:02:44,400 and we'll be getting to them in a bit 73 00:02:49,750 --> 00:02:47,200 but now to kind of describe the in situ 74 00:02:52,390 --> 00:02:49,760 instrument laboratory i'd like to have 75 00:02:53,910 --> 00:02:52,400 prenay come over here and do 76 00:02:55,509 --> 00:02:53,920 we'll explain that little dance you have 77 00:02:58,470 --> 00:02:55,519 to do with the instruments before but 78 00:03:00,390 --> 00:02:58,480 can you explain why this type of room is 79 00:03:02,630 --> 00:03:00,400 important for mars missions absolutely 80 00:03:04,309 --> 00:03:02,640 so the activities we complete on mars 81 00:03:06,309 --> 00:03:04,319 with both our landers and our rovers are 82 00:03:08,710 --> 00:03:06,319 very complex and we want to give them 83 00:03:10,710 --> 00:03:08,720 the best chance of success so in a 84 00:03:13,110 --> 00:03:10,720 facility like this with a test bed like 85 00:03:14,470 --> 00:03:13,120 this we actually test all the complex 86 00:03:16,550 --> 00:03:14,480 activities that we're going to perform 87 00:03:18,630 --> 00:03:16,560 on mars in here first we'll write a 88 00:03:20,470 --> 00:03:18,640 sequence we'll test it out here in this 89 00:03:22,149 --> 00:03:20,480 facility we'll see what went right what 90 00:03:23,910 --> 00:03:22,159 went wrong make some tweaks and 91 00:03:25,110 --> 00:03:23,920 eventually when it goes right in here 92 00:03:27,110 --> 00:03:25,120 we'll send it to mars so that it 93 00:03:28,710 --> 00:03:27,120 executes successfully there and i had a 94 00:03:31,110 --> 00:03:28,720 question about kind of everything we're 95 00:03:34,309 --> 00:03:31,120 stepping on this gravel like why does 96 00:03:36,710 --> 00:03:34,319 this have to be here for the uh 97 00:03:38,070 --> 00:03:36,720 sure so what this actually is if you 98 00:03:39,750 --> 00:03:38,080 take a look most people might think 99 00:03:42,149 --> 00:03:39,760 they're just some rocks you find outside 100 00:03:43,990 --> 00:03:42,159 but this is actually crushed unprocessed 101 00:03:46,789 --> 00:03:44,000 garnet and when you think of garnet you 102 00:03:48,309 --> 00:03:46,799 think of jewelry but this is the version 103 00:03:49,990 --> 00:03:48,319 before it turns into that so if you 104 00:03:51,589 --> 00:03:50,000 actually pick some pieces out and hold 105 00:03:53,589 --> 00:03:51,599 them into the light you can see little 106 00:03:55,990 --> 00:03:53,599 glints of red for the jewelry that they 107 00:03:57,990 --> 00:03:56,000 could one day become in here we use them 108 00:04:00,550 --> 00:03:58,000 as our practice deployment surface for 109 00:04:01,830 --> 00:04:00,560 insights so we have tiny rock polisher 110 00:04:04,949 --> 00:04:01,840 that's right that's right just a little 111 00:04:08,070 --> 00:04:04,959 bit of jewelry here and then uh also why 112 00:04:11,030 --> 00:04:08,080 are you both clipped into the foresight 113 00:04:12,949 --> 00:04:11,040 right now so foresight and most test 114 00:04:14,949 --> 00:04:12,959 beds have very sensitive electronics 115 00:04:17,749 --> 00:04:14,959 both to temperature and things like 116 00:04:19,830 --> 00:04:17,759 electrostatic discharge and so to ensure 117 00:04:22,069 --> 00:04:19,840 that myself or mark or anyone who's 118 00:04:24,310 --> 00:04:22,079 close to these electronics doesn't cause 119 00:04:25,830 --> 00:04:24,320 any accidental electrostatic discharge 120 00:04:28,469 --> 00:04:25,840 we use these things called grounding 121 00:04:30,150 --> 00:04:28,479 straps connect to a ground wire here to 122 00:04:32,550 --> 00:04:30,160 ensure that there's no chance that we 123 00:04:34,870 --> 00:04:32,560 can danger these electronics same for 124 00:04:36,390 --> 00:04:34,880 the ac that was mentioned earlier 125 00:04:37,830 --> 00:04:36,400 these electronics are sensitive to 126 00:04:39,909 --> 00:04:37,840 temperature we don't want it to get too 127 00:04:41,909 --> 00:04:39,919 hot in here otherwise that might damage 128 00:04:43,590 --> 00:04:41,919 it so we have this very loud ac going to 129 00:04:45,590 --> 00:04:43,600 ensure that it stays cool in this room 130 00:04:48,230 --> 00:04:45,600 all right so if you see them do a little 131 00:04:49,830 --> 00:04:48,240 dance that's why they're keeping the uh 132 00:04:51,990 --> 00:04:49,840 the foresight safe and speaking of 133 00:04:54,550 --> 00:04:52,000 foresight can you kind of go through 134 00:04:56,710 --> 00:04:54,560 some of the parts that we see here sure 135 00:04:58,710 --> 00:04:56,720 so if we start from a far view what we 136 00:05:00,710 --> 00:04:58,720 have here is foresight's deck it's the 137 00:05:02,150 --> 00:05:00,720 same size as insights deck and as you 138 00:05:03,749 --> 00:05:02,160 mentioned before we just don't have 139 00:05:04,469 --> 00:05:03,759 solar panels on it 140 00:05:08,870 --> 00:05:04,479 the 141 00:05:11,909 --> 00:05:08,880 see in photos is our 142 00:05:14,790 --> 00:05:11,919 instrument deployment arm the idea 143 00:05:16,469 --> 00:05:14,800 so this arm is what was used to deploy 144 00:05:19,350 --> 00:05:16,479 all our deployables onto the surface of 145 00:05:20,790 --> 00:05:19,360 mars there are two cameras on insight 146 00:05:23,350 --> 00:05:20,800 and so we have two cameras here on 147 00:05:25,189 --> 00:05:23,360 foresight the first one is the idc 148 00:05:27,909 --> 00:05:25,199 the instrument deployment camera and 149 00:05:29,430 --> 00:05:27,919 that's that red box attached to the arm 150 00:05:31,189 --> 00:05:29,440 and then we have a second camera we'll 151 00:05:33,430 --> 00:05:31,199 have to swing around a little bit but we 152 00:05:35,590 --> 00:05:33,440 have a second camera there's a red box 153 00:05:37,749 --> 00:05:35,600 to my right that is our instrument 154 00:05:38,390 --> 00:05:37,759 context camera or icc so when you see 155 00:05:40,310 --> 00:05:38,400 the 156 00:05:42,629 --> 00:05:40,320 fixed landscape images come back from 157 00:05:44,629 --> 00:05:42,639 insight that's from the icc and anytime 158 00:05:46,390 --> 00:05:44,639 you see images of the deck or close-ups 159 00:05:49,029 --> 00:05:46,400 of the instruments that's coming from 160 00:05:51,270 --> 00:05:49,039 our idc speaking of instruments mark had 161 00:05:54,150 --> 00:05:51,280 already mentioned the seismometer to my 162 00:05:55,909 --> 00:05:54,160 right which is this orange hexagon here 163 00:05:57,749 --> 00:05:55,919 in our photos what you typically see is 164 00:06:00,629 --> 00:05:57,759 this white dome called the wind and 165 00:06:02,390 --> 00:06:00,639 thermal shield abbreviated to wts this 166 00:06:04,469 --> 00:06:02,400 is placed on top of the seismometer to 167 00:06:06,870 --> 00:06:04,479 ensure we don't have any noise or less 168 00:06:09,029 --> 00:06:06,880 noise in our data taken from the 169 00:06:11,990 --> 00:06:09,039 seismometer and here 170 00:06:14,710 --> 00:06:12,000 we have a model of the hp3 which is our 171 00:06:16,230 --> 00:06:14,720 the mole the penetrator uh and so these 172 00:06:18,469 --> 00:06:16,240 are the three items that we practice 173 00:06:19,430 --> 00:06:18,479 deploying in this testbed and what has 174 00:06:21,350 --> 00:06:19,440 kind of been some of the most 175 00:06:23,909 --> 00:06:21,360 significant and important tests you've 176 00:06:26,150 --> 00:06:23,919 done since insight landed the most 177 00:06:28,309 --> 00:06:26,160 important test we did was practicing 178 00:06:29,909 --> 00:06:28,319 these deployments before we landed we 179 00:06:31,830 --> 00:06:29,919 weren't sure what the terrain would look 180 00:06:34,070 --> 00:06:31,840 like we could have a tilt 181 00:06:36,550 --> 00:06:34,080 we could have rocks in our workspace so 182 00:06:38,390 --> 00:06:36,560 in this room we would add rocks to our 183 00:06:40,710 --> 00:06:38,400 field we would set up boards with 184 00:06:42,550 --> 00:06:40,720 different tilts up to 15 degrees and 185 00:06:43,990 --> 00:06:42,560 these items would be up here on the deck 186 00:06:45,909 --> 00:06:44,000 and we would use the robotic arm and 187 00:06:47,350 --> 00:06:45,919 practice lifting them and putting them 188 00:06:49,270 --> 00:06:47,360 onto the surface we wanted to make sure 189 00:06:50,790 --> 00:06:49,280 we had good accuracy and good precision 190 00:06:52,309 --> 00:06:50,800 so when the scientists told us where 191 00:06:53,670 --> 00:06:52,319 they wanted these on the surface we 192 00:06:55,430 --> 00:06:53,680 could get them there all right and 193 00:06:57,589 --> 00:06:55,440 speaking of scientists 194 00:07:00,070 --> 00:06:57,599 mark i have some questions for you 195 00:07:02,710 --> 00:07:00,080 what have scientists learned from 196 00:07:04,390 --> 00:07:02,720 insight yeah so um 197 00:07:06,309 --> 00:07:04,400 as i said our our main mission goals 198 00:07:08,390 --> 00:07:06,319 were to look at the interior mars in 199 00:07:10,950 --> 00:07:08,400 particular we wanted to know more about 200 00:07:12,550 --> 00:07:10,960 its crust which is the rocky layer on 201 00:07:14,230 --> 00:07:12,560 the outside it's mantle which is the 202 00:07:16,550 --> 00:07:14,240 rocky layer below it and its core which 203 00:07:18,710 --> 00:07:16,560 is the metallic layer in the middle and 204 00:07:20,309 --> 00:07:18,720 uh by looking at all of those mars 205 00:07:22,790 --> 00:07:20,319 quakes we've talked about so there's 206 00:07:23,589 --> 00:07:22,800 over 1300 of them recorded we can look 207 00:07:29,589 --> 00:07:23,599 at 208 00:07:30,950 --> 00:07:29,599 insight go through the inside of mars 209 00:07:32,790 --> 00:07:30,960 and use that to figure out what's 210 00:07:35,990 --> 00:07:32,800 happening on the inside of mars so we 211 00:07:38,150 --> 00:07:36,000 can now tell how thick the crust is um 212 00:07:40,150 --> 00:07:38,160 it's not as thick as some models 213 00:07:42,070 --> 00:07:40,160 suggested before but it's uh 214 00:07:44,629 --> 00:07:42,080 it makes a lot of sense we can now tell 215 00:07:46,070 --> 00:07:44,639 how big the core is it's actually ended 216 00:07:47,670 --> 00:07:46,080 up being on the big end of our 217 00:07:49,670 --> 00:07:47,680 expectations which is actually going to 218 00:07:51,189 --> 00:07:49,680 be very interesting moving forward and 219 00:07:53,909 --> 00:07:51,199 trying to understand the science of how 220 00:07:55,749 --> 00:07:53,919 mars formed and evolved if it's big it's 221 00:07:57,990 --> 00:07:55,759 also less dense and that tells you stuff 222 00:07:59,029 --> 00:07:58,000 about the kinds of stuff inside the 223 00:08:00,869 --> 00:07:59,039 court 224 00:08:03,189 --> 00:08:00,879 we're also really interested in how 225 00:08:04,629 --> 00:08:03,199 active mars is all those mars quakes we 226 00:08:06,070 --> 00:08:04,639 recorded we need to know why they're 227 00:08:07,510 --> 00:08:06,080 happening and where they're happening 228 00:08:09,189 --> 00:08:07,520 and some of the most interesting stuff 229 00:08:12,070 --> 00:08:09,199 is that many of those quakes happen in 230 00:08:14,309 --> 00:08:12,080 an area we call cerberus fosse which 231 00:08:15,749 --> 00:08:14,319 geologically speaking is very young in 232 00:08:17,589 --> 00:08:15,759 terms of volcanoes now when i say 233 00:08:19,589 --> 00:08:17,599 geologically young it's 234 00:08:23,510 --> 00:08:19,599 less than 10 million years old 235 00:08:25,110 --> 00:08:23,520 but we we know has steep sides on its 236 00:08:26,790 --> 00:08:25,120 features that have rock falls that go 237 00:08:28,790 --> 00:08:26,800 down them and we suspected going into 238 00:08:30,869 --> 00:08:28,800 the mission that we would see marsquakes 239 00:08:33,350 --> 00:08:30,879 there and it turns out we did see mars 240 00:08:35,350 --> 00:08:33,360 quakes there um and also many marsquakes 241 00:08:36,870 --> 00:08:35,360 uh all around the the planet so there's 242 00:08:38,230 --> 00:08:36,880 there's been a lot of uh really 243 00:08:40,389 --> 00:08:38,240 interesting science to come out and a 244 00:08:42,389 --> 00:08:40,399 lot of science to come yeah speaking of 245 00:08:45,190 --> 00:08:42,399 science to come will you be able to use 246 00:08:47,350 --> 00:08:45,200 the data that you have received and 247 00:08:50,630 --> 00:08:47,360 continue to receive in the future 248 00:08:53,430 --> 00:08:50,640 absolutely so um i i like to reference 249 00:08:55,030 --> 00:08:53,440 back to the apollo missions so they 250 00:08:56,790 --> 00:08:55,040 landed seismometers on the moon that 251 00:08:59,590 --> 00:08:56,800 operated after the astronauts left and 252 00:09:01,910 --> 00:08:59,600 they kept operating until 1977 253 00:09:04,230 --> 00:09:01,920 um but then they got turned off in 1977 254 00:09:06,710 --> 00:09:04,240 but people are still making studies on 255 00:09:07,430 --> 00:09:06,720 those quakes today 256 00:09:08,949 --> 00:09:07,440 and 257 00:09:10,389 --> 00:09:08,959 there's every reason to think people are 258 00:09:11,750 --> 00:09:10,399 still going to be studying mars quakes 259 00:09:13,990 --> 00:09:11,760 from insight 260 00:09:16,790 --> 00:09:14,000 for decades to come in fact all the data 261 00:09:19,110 --> 00:09:16,800 is publicly available um 262 00:09:20,790 --> 00:09:19,120 with a slight delay but most of the most 263 00:09:22,070 --> 00:09:20,800 of the data for the mission you can just 264 00:09:23,750 --> 00:09:22,080 download from the sites that 265 00:09:25,590 --> 00:09:23,760 seismologists work from whether you're 266 00:09:27,350 --> 00:09:25,600 on the science team or not 267 00:09:29,430 --> 00:09:27,360 lots of science years ahead and i do 268 00:09:32,310 --> 00:09:29,440 like the aspect that the public can also 269 00:09:33,990 --> 00:09:32,320 access it as well and we are getting 270 00:09:36,389 --> 00:09:34,000 some viewer questions in so if you're 271 00:09:37,829 --> 00:09:36,399 just tuning in we are asking some 272 00:09:39,910 --> 00:09:37,839 questions about insight and won't be 273 00:09:42,310 --> 00:09:39,920 answering your questions use the hashtag 274 00:09:46,070 --> 00:09:42,320 asknasa or drop them in the comments 275 00:09:48,630 --> 00:09:46,080 below and first off for mark we have 276 00:09:49,990 --> 00:09:48,640 roshana who asks will there be a future 277 00:09:54,070 --> 00:09:50,000 mission that will follow up in the 278 00:09:57,030 --> 00:09:54,080 discoveries made by the insight lander 279 00:10:00,310 --> 00:09:57,040 the short answer is i don't know 280 00:10:02,710 --> 00:10:00,320 those decisions are are made by nasa 281 00:10:04,150 --> 00:10:02,720 and so i have ideas for some great 282 00:10:05,750 --> 00:10:04,160 things we could do it would be great to 283 00:10:07,829 --> 00:10:05,760 have a mission someday that went to 284 00:10:10,389 --> 00:10:07,839 servers fosa and looked at mars quakes 285 00:10:11,590 --> 00:10:10,399 um and there are uh i have certainly 286 00:10:12,710 --> 00:10:11,600 going to be 287 00:10:14,790 --> 00:10:12,720 um 288 00:10:16,230 --> 00:10:14,800 people that are proposing missions to go 289 00:10:18,550 --> 00:10:16,240 back to mars but 290 00:10:19,750 --> 00:10:18,560 uh we can't predict exactly what's going 291 00:10:22,389 --> 00:10:19,760 to happen 292 00:10:24,069 --> 00:10:22,399 and i have another question coming in 293 00:10:25,590 --> 00:10:24,079 from cynical led 294 00:10:27,990 --> 00:10:25,600 they i think this is going to be for 295 00:10:30,470 --> 00:10:28,000 prenate what happens if the solar arrays 296 00:10:33,030 --> 00:10:30,480 are cleaned off by wind will you bring 297 00:10:34,949 --> 00:10:33,040 the mission out of retirement 298 00:10:36,150 --> 00:10:34,959 so i can't speak to the last part of the 299 00:10:38,389 --> 00:10:36,160 question about bringing it out of 300 00:10:40,389 --> 00:10:38,399 retirement that's a very broad question 301 00:10:43,030 --> 00:10:40,399 if we could be able to do that but 302 00:10:44,870 --> 00:10:43,040 if there was a cleaning event on the 303 00:10:47,590 --> 00:10:44,880 solar panels we would expect to have 304 00:10:49,110 --> 00:10:47,600 more power in our batteries and insight 305 00:10:51,030 --> 00:10:49,120 would be able to operate for a longer 306 00:10:52,550 --> 00:10:51,040 amount of time when that happens and if 307 00:10:53,430 --> 00:10:52,560 that happens unfortunately it's not up 308 00:10:55,590 --> 00:10:53,440 to us 309 00:10:57,910 --> 00:10:55,600 okay i would i would like to follow up 310 00:10:59,910 --> 00:10:57,920 on that real quick so one thing we do 311 00:11:02,870 --> 00:10:59,920 know about how the spacecraft is 312 00:11:04,870 --> 00:11:02,880 designed is that 313 00:11:06,389 --> 00:11:04,880 at some point it won't deliver enough 314 00:11:07,829 --> 00:11:06,399 energy to keep the batteries charged up 315 00:11:10,550 --> 00:11:07,839 and we'll stop communicating with it we 316 00:11:11,670 --> 00:11:10,560 expect that to happen sometime this year 317 00:11:14,389 --> 00:11:11,680 but 318 00:11:17,590 --> 00:11:14,399 if in the future the solar panels were 319 00:11:19,509 --> 00:11:17,600 were cleaned off it's the spacecraft 320 00:11:20,710 --> 00:11:19,519 design that it would then start charging 321 00:11:22,550 --> 00:11:20,720 up the batteries 322 00:11:25,350 --> 00:11:22,560 and it would 323 00:11:27,430 --> 00:11:25,360 start to try to communicate with earth 324 00:11:29,670 --> 00:11:27,440 and there's a chance that we could hear 325 00:11:32,150 --> 00:11:29,680 it again and bring it back it's 326 00:11:35,509 --> 00:11:32,160 possible it's designed to be able to do 327 00:11:38,069 --> 00:11:35,519 that but once again that's depends on 328 00:11:39,110 --> 00:11:38,079 what mars does and so we can't predict 329 00:11:40,710 --> 00:11:39,120 what's going to happen but the 330 00:11:43,350 --> 00:11:40,720 spacecraft is designed to be able to 331 00:11:46,710 --> 00:11:43,360 recover from its battery being drained 332 00:11:49,350 --> 00:11:46,720 that's a nice hopeful answer so uh we 333 00:11:52,550 --> 00:11:49,360 have some people commenting on what they 334 00:11:54,310 --> 00:11:52,560 see behind us and how foresight is kind 335 00:11:57,269 --> 00:11:54,320 of on these blocks 336 00:11:59,030 --> 00:11:57,279 could you kind of explain why that is 337 00:12:01,509 --> 00:11:59,040 sure so 338 00:12:03,030 --> 00:12:01,519 as most people know insight is a lander 339 00:12:05,190 --> 00:12:03,040 so it does not have any wheels and it 340 00:12:07,269 --> 00:12:05,200 doesn't move so one of the things we 341 00:12:09,829 --> 00:12:07,279 like to test in this room using 342 00:12:12,150 --> 00:12:09,839 foresight is besides the deployments is 343 00:12:13,990 --> 00:12:12,160 when the hp3 mole anomaly occurred we 344 00:12:16,310 --> 00:12:14,000 wanted to ensure that we could test 345 00:12:18,389 --> 00:12:16,320 every possible solution in the space 346 00:12:21,350 --> 00:12:18,399 what we actually did was we had brought 347 00:12:23,190 --> 00:12:21,360 in the flight spare for our mole brought 348 00:12:25,990 --> 00:12:23,200 it to this room here connected it to 349 00:12:27,190 --> 00:12:26,000 foresight and we set up a box in this 350 00:12:28,230 --> 00:12:27,200 space 351 00:12:30,550 --> 00:12:28,240 to give 352 00:12:32,550 --> 00:12:30,560 time and depth for the mole to actually 353 00:12:34,949 --> 00:12:32,560 penetrate if we needed to during our 354 00:12:36,550 --> 00:12:34,959 testing so we needed space downward for 355 00:12:38,310 --> 00:12:36,560 the mole to penetrate so we actually had 356 00:12:40,550 --> 00:12:38,320 to raise the lander up using these 357 00:12:41,990 --> 00:12:40,560 cinder blocks to ensure that the height 358 00:12:44,310 --> 00:12:42,000 between the deck 359 00:12:46,629 --> 00:12:44,320 the robotic arm and the mole in our 360 00:12:48,470 --> 00:12:46,639 testing area was the same as on mars to 361 00:12:50,470 --> 00:12:48,480 ensure that we were actually testing in 362 00:12:51,990 --> 00:12:50,480 a flight-like way 363 00:12:54,550 --> 00:12:52,000 it's fun to see like all these little 364 00:12:56,470 --> 00:12:54,560 parts and how they have one specific use 365 00:12:58,069 --> 00:12:56,480 in here that's right this is our play 366 00:12:58,949 --> 00:12:58,079 sandbox this is the best part about this 367 00:13:00,550 --> 00:12:58,959 job 368 00:13:02,069 --> 00:13:00,560 and we have some more questions coming 369 00:13:03,750 --> 00:13:02,079 in about the signs again if you'd like 370 00:13:05,670 --> 00:13:03,760 to ask a question about insight use the 371 00:13:06,389 --> 00:13:05,680 ask nasa 372 00:13:08,310 --> 00:13:06,399 or 373 00:13:10,470 --> 00:13:08,320 drop them in the comments below and they 374 00:13:11,509 --> 00:13:10,480 are patiently doing their dances they 375 00:13:13,269 --> 00:13:11,519 try to 376 00:13:16,069 --> 00:13:13,279 make sure that they are connected to the 377 00:13:18,069 --> 00:13:16,079 spacecraft uh dan shields asks will 378 00:13:21,190 --> 00:13:18,079 there be seismic instruments in the 379 00:13:23,350 --> 00:13:21,200 upcoming venus missions upcoming venus 380 00:13:25,269 --> 00:13:23,360 mission so at this point the the venus 381 00:13:27,509 --> 00:13:25,279 missions that have been selected none of 382 00:13:29,509 --> 00:13:27,519 them are going to the surface 383 00:13:32,069 --> 00:13:29,519 so there wouldn't be any seismic 384 00:13:35,509 --> 00:13:32,079 instruments on those um there have been 385 00:13:38,310 --> 00:13:35,519 proposals for uh possible ways of doing 386 00:13:39,910 --> 00:13:38,320 seismology on venus from orbit 387 00:13:42,310 --> 00:13:39,920 but it would be very different than what 388 00:13:43,990 --> 00:13:42,320 we're doing on insight um so if there is 389 00:13:45,030 --> 00:13:44,000 possibility in the future but in the 390 00:13:47,110 --> 00:13:45,040 currently 391 00:13:49,430 --> 00:13:47,120 selected missions uh there's no plan for 392 00:13:51,750 --> 00:13:49,440 seismology and you know someone was just 393 00:13:53,110 --> 00:13:51,760 asking again what what is this what are 394 00:13:55,110 --> 00:13:53,120 these little bracelets that you're 395 00:13:56,550 --> 00:13:55,120 wearing sure so 396 00:13:59,030 --> 00:13:56,560 uh we have a lot of sensitive 397 00:14:00,230 --> 00:13:59,040 electronics in our test bed area and 398 00:14:01,350 --> 00:14:00,240 they are sensitive to things like 399 00:14:03,670 --> 00:14:01,360 temperature and the other thing is 400 00:14:05,590 --> 00:14:03,680 electrostatic discharge esd so if you 401 00:14:07,350 --> 00:14:05,600 ever touch a doorknob a metal doorknob 402 00:14:08,629 --> 00:14:07,360 and get a little static shock that's 403 00:14:09,910 --> 00:14:08,639 what we're trying to prevent here we 404 00:14:11,590 --> 00:14:09,920 don't want any of those shocks to go 405 00:14:14,310 --> 00:14:11,600 into our electronics and cause any 406 00:14:16,470 --> 00:14:14,320 damage what these wrist straps do is 407 00:14:18,870 --> 00:14:16,480 they ground ourselves 408 00:14:20,629 --> 00:14:18,880 through the spacecraft to our facility 409 00:14:22,470 --> 00:14:20,639 ground so they make sure that if we have 410 00:14:24,150 --> 00:14:22,480 any charge it passes through safely and 411 00:14:26,150 --> 00:14:24,160 doesn't actually affect our electronics 412 00:14:27,670 --> 00:14:26,160 and we can't cause any damage we wear 413 00:14:29,430 --> 00:14:27,680 these when we are close to the 414 00:14:31,990 --> 00:14:29,440 electronics if you're a certain distance 415 00:14:33,670 --> 00:14:32,000 away then you don't need to wear one 416 00:14:36,069 --> 00:14:33,680 great and then we have a couple science 417 00:14:38,470 --> 00:14:36,079 questions coming in now derek ward asked 418 00:14:40,069 --> 00:14:38,480 what is the core made of and does the 419 00:14:43,110 --> 00:14:40,079 core have a 420 00:14:44,550 --> 00:14:43,120 solid core or is it all liquid 421 00:14:45,990 --> 00:14:44,560 that's a really good question and the 422 00:14:48,790 --> 00:14:46,000 short answer is we don't know all of 423 00:14:53,430 --> 00:14:48,800 those answers yet but what i will say 424 00:14:54,949 --> 00:14:53,440 is that the core is metallic its main 425 00:14:56,470 --> 00:14:54,959 main constituents are like the earth 426 00:14:58,230 --> 00:14:56,480 iron and nickel 427 00:15:00,389 --> 00:14:58,240 but its density is low enough that it 428 00:15:01,910 --> 00:15:00,399 has other things in it we don't know 429 00:15:04,069 --> 00:15:01,920 exactly what all of the other things are 430 00:15:05,829 --> 00:15:04,079 a lot of it is probably sulfur 431 00:15:07,750 --> 00:15:05,839 but there are other things carbon 432 00:15:09,110 --> 00:15:07,760 hydrogen other lighter elements that 433 00:15:10,790 --> 00:15:09,120 could be in there to make it be less 434 00:15:12,629 --> 00:15:10,800 dense and we're still trying to work out 435 00:15:15,509 --> 00:15:12,639 what all of those could be in terms of 436 00:15:17,430 --> 00:15:15,519 whether it's liquid or solid we can say 437 00:15:20,230 --> 00:15:17,440 with a high level of certainty that at 438 00:15:22,310 --> 00:15:20,240 the top of the core it's liquid uh we 439 00:15:24,310 --> 00:15:22,320 know that for sure um 440 00:15:26,870 --> 00:15:24,320 because the seismic energy we see 441 00:15:28,870 --> 00:15:26,880 reflects very strongly and also the 442 00:15:30,550 --> 00:15:28,880 radio science tells us that the motions 443 00:15:31,990 --> 00:15:30,560 of the planet are consistent with a 444 00:15:34,150 --> 00:15:32,000 liquid core 445 00:15:36,629 --> 00:15:34,160 at the the where the core 446 00:15:39,189 --> 00:15:36,639 and the rocky mantle come together 447 00:15:41,430 --> 00:15:39,199 we can't say for certain whether it has 448 00:15:42,949 --> 00:15:41,440 a solid inner core like the earth does 449 00:15:45,189 --> 00:15:42,959 we don't have any evidence to say one 450 00:15:46,470 --> 00:15:45,199 way or the other but i will say 451 00:15:48,230 --> 00:15:46,480 under the pressure and temperature 452 00:15:50,069 --> 00:15:48,240 conditions of mars 453 00:15:51,749 --> 00:15:50,079 it's likely that it's all liquid but we 454 00:15:53,749 --> 00:15:51,759 don't know that for sure 455 00:15:56,230 --> 00:15:53,759 more answers to come and then war hero 456 00:15:58,790 --> 00:15:56,240 asks how long was the mission designed 457 00:16:01,269 --> 00:15:58,800 to last and did the mission meet 458 00:16:03,829 --> 00:16:01,279 everyone's expectations when it comes to 459 00:16:05,990 --> 00:16:03,839 the science that came from it absolutely 460 00:16:07,509 --> 00:16:06,000 so our prime mission was schedule was 461 00:16:10,069 --> 00:16:07,519 scheduled to last 462 00:16:13,350 --> 00:16:10,079 about one mars year two earth years 463 00:16:15,189 --> 00:16:13,360 approximately um and we uh designed the 464 00:16:16,470 --> 00:16:15,199 solar panels such that we wouldn't be 465 00:16:18,710 --> 00:16:16,480 sure to have enough energy to get 466 00:16:19,990 --> 00:16:18,720 through that and we did we had plenty of 467 00:16:22,150 --> 00:16:20,000 energy to get through the prime mission 468 00:16:23,910 --> 00:16:22,160 in fact we got another extended mission 469 00:16:25,269 --> 00:16:23,920 that we're in right now that extended it 470 00:16:27,350 --> 00:16:25,279 another two years 471 00:16:30,150 --> 00:16:27,360 um uh we recorded 472 00:16:32,150 --> 00:16:30,160 a whole lot of events we've answered all 473 00:16:34,069 --> 00:16:32,160 of our science goals uh and so we 474 00:16:35,910 --> 00:16:34,079 actually got to looking at the interior 475 00:16:37,749 --> 00:16:35,920 of mars and we're actually extremely 476 00:16:39,269 --> 00:16:37,759 happy with the amount of science we've 477 00:16:41,829 --> 00:16:39,279 been able to achieve and there's still 478 00:16:43,430 --> 00:16:41,839 more happening uh i 479 00:16:45,829 --> 00:16:43,440 didn't mention it but we actually had 480 00:16:48,790 --> 00:16:45,839 the biggest event of the mission just 481 00:16:51,910 --> 00:16:48,800 about a month and a half ago um and uh 482 00:16:53,670 --> 00:16:51,920 and there are so many studies that are 483 00:16:55,110 --> 00:16:53,680 underway looking at all of the new data 484 00:16:56,949 --> 00:16:55,120 we can get with such a big event and 485 00:16:59,509 --> 00:16:56,959 when i say big event it was magnitude 486 00:17:01,509 --> 00:16:59,519 4.7 which on earth isn't that big but on 487 00:17:02,550 --> 00:17:01,519 mars was far bigger than anything else 488 00:17:03,829 --> 00:17:02,560 we'd seen 489 00:17:05,510 --> 00:17:03,839 and i just want you to know that you 490 00:17:08,710 --> 00:17:05,520 have a fan watching right now your 491 00:17:14,789 --> 00:17:11,990 so you're doing great here and uh 492 00:17:18,549 --> 00:17:14,799 i'd also like to know uh 493 00:17:22,069 --> 00:17:18,559 why has the seismometer gone on longer 494 00:17:23,909 --> 00:17:22,079 than previously planned um 495 00:17:27,029 --> 00:17:23,919 more phrasing i think is they want to 496 00:17:28,710 --> 00:17:27,039 know is could using this seismometer 497 00:17:31,510 --> 00:17:28,720 cause it to accidentally shut down 498 00:17:33,510 --> 00:17:31,520 unexpectedly by continuing to use it so 499 00:17:36,390 --> 00:17:33,520 um i will say 500 00:17:39,430 --> 00:17:36,400 we had a time period this is very 501 00:17:41,190 --> 00:17:39,440 interesting stuff happened uh back 502 00:17:44,390 --> 00:17:41,200 about uh 503 00:17:46,070 --> 00:17:44,400 late last summer in 2021 we were 504 00:17:48,070 --> 00:17:46,080 entering the time of the mars season 505 00:17:50,230 --> 00:17:48,080 called aphelion when it's farthest from 506 00:17:51,830 --> 00:17:50,240 the sun and at that point 507 00:17:53,669 --> 00:17:51,840 we're farthest from the sun so we got 508 00:17:55,990 --> 00:17:53,679 the lowest amount of solar energy and we 509 00:17:57,430 --> 00:17:56,000 were at our coldest temperatures and we 510 00:17:58,789 --> 00:17:57,440 were very concerned that we weren't 511 00:18:00,470 --> 00:17:58,799 going to be able to continue operating 512 00:18:03,029 --> 00:18:00,480 instruments through that time 513 00:18:05,510 --> 00:18:03,039 the engineers including here in the test 514 00:18:07,750 --> 00:18:05,520 bed and mult multiple places came up 515 00:18:09,350 --> 00:18:07,760 with lots of great plans uh to try to 516 00:18:12,710 --> 00:18:09,360 get a little more energy out and they 517 00:18:15,590 --> 00:18:12,720 dumped actual rocks on top of the deck 518 00:18:16,710 --> 00:18:15,600 that then blew across the solar panels 519 00:18:17,990 --> 00:18:16,720 and cleaned them off a little bit and 520 00:18:19,270 --> 00:18:18,000 kept us going for longer than we 521 00:18:21,029 --> 00:18:19,280 expected 522 00:18:23,029 --> 00:18:21,039 and that's 523 00:18:24,789 --> 00:18:23,039 an amazing thing and i have all sorts of 524 00:18:26,950 --> 00:18:24,799 compliments for the engineers for for 525 00:18:29,830 --> 00:18:26,960 for making that work 526 00:18:31,510 --> 00:18:29,840 but right now we are not no longer 527 00:18:33,990 --> 00:18:31,520 running the seismometer continuously 528 00:18:36,789 --> 00:18:34,000 we're running it about half of the time 529 00:18:39,350 --> 00:18:36,799 um we are carefully monitoring energy so 530 00:18:42,390 --> 00:18:39,360 it's not at this point going to make the 531 00:18:44,470 --> 00:18:42,400 the spacecraft stop operating 532 00:18:46,870 --> 00:18:44,480 but at some point we're going to get to 533 00:18:49,669 --> 00:18:46,880 a point where we may not be able 534 00:18:51,510 --> 00:18:49,679 to keep doing that but the engineers are 535 00:18:54,150 --> 00:18:51,520 keeping close eye on all of that 536 00:18:56,150 --> 00:18:54,160 yeah yeah thanks to prenatal there's a 537 00:18:58,390 --> 00:18:56,160 large operations team that that mark was 538 00:18:59,750 --> 00:18:58,400 mentioning that every day models energy 539 00:19:01,510 --> 00:18:59,760 looks at the data that's coming back 540 00:19:03,350 --> 00:19:01,520 plans how to use the instruments so that 541 00:19:06,150 --> 00:19:03,360 we have enough power so there's a huge 542 00:19:08,710 --> 00:19:06,160 team behind all the success for insight 543 00:19:10,470 --> 00:19:08,720 absolutely and we were getting some 544 00:19:12,789 --> 00:19:10,480 questions kind of just about the room in 545 00:19:15,270 --> 00:19:12,799 general so this has been used like 546 00:19:16,789 --> 00:19:15,280 historically not just for insight there 547 00:19:19,029 --> 00:19:16,799 have been many other missions and kind 548 00:19:20,630 --> 00:19:19,039 of what you see behind there is from a 549 00:19:22,310 --> 00:19:20,640 previous rover mission and there's all 550 00:19:24,789 --> 00:19:22,320 these uh different parts here could you 551 00:19:26,950 --> 00:19:24,799 kind of get into that too sure so one of 552 00:19:28,710 --> 00:19:26,960 the first missions tested here are the 553 00:19:30,390 --> 00:19:28,720 spirit and opportunity rovers so 554 00:19:32,710 --> 00:19:30,400 actually at that time there was a whole 555 00:19:34,630 --> 00:19:32,720 different surface in here 556 00:19:37,430 --> 00:19:34,640 but this building was built to test 557 00:19:39,510 --> 00:19:37,440 those two rovers after they had left 558 00:19:41,270 --> 00:19:39,520 curiosity for some aspects were tested 559 00:19:43,990 --> 00:19:41,280 in here their test bed was here just 560 00:19:45,669 --> 00:19:44,000 recently perseverance landed on mars and 561 00:19:48,390 --> 00:19:45,679 so they're tested they're our neighbor 562 00:19:50,390 --> 00:19:48,400 so we play together in the sandbox area 563 00:19:52,870 --> 00:19:50,400 going forward new missions will use this 564 00:19:55,110 --> 00:19:52,880 building so this was created as a test 565 00:19:57,190 --> 00:19:55,120 environment and as a universal test 566 00:19:58,630 --> 00:19:57,200 environment so we can reshape it every 567 00:20:00,070 --> 00:19:58,640 time we have a new mission that needs 568 00:20:01,990 --> 00:20:00,080 space one of the things you were 569 00:20:04,789 --> 00:20:02,000 mentioning behind me the black and white 570 00:20:06,549 --> 00:20:04,799 dots are a cal target so for some of our 571 00:20:07,909 --> 00:20:06,559 rover missions that were in here they 572 00:20:09,990 --> 00:20:07,919 were testing some of their cameras and 573 00:20:12,310 --> 00:20:10,000 doing some calibration they used that 574 00:20:14,549 --> 00:20:12,320 target to test out their cameras and 575 00:20:16,470 --> 00:20:14,559 you've also mentioned too these other 576 00:20:17,909 --> 00:20:16,480 cameras around here what are the four 577 00:20:20,470 --> 00:20:17,919 cameras 578 00:20:22,470 --> 00:20:20,480 all around us are they for insight yeah 579 00:20:24,390 --> 00:20:22,480 so we have these four and they look 580 00:20:26,470 --> 00:20:24,400 little black and silver cameras going 581 00:20:28,870 --> 00:20:26,480 all around the insight test bed those 582 00:20:30,549 --> 00:20:28,880 are called vicon motion capture cameras 583 00:20:32,390 --> 00:20:30,559 so they're commonly used in hollywood 584 00:20:34,549 --> 00:20:32,400 and video game design 585 00:20:36,470 --> 00:20:34,559 and they do precision motion tracking 586 00:20:38,630 --> 00:20:36,480 what we use them for is after we 587 00:20:41,750 --> 00:20:38,640 practice each deployment we actually put 588 00:20:44,630 --> 00:20:41,760 a tracking dot from these cameras on the 589 00:20:46,630 --> 00:20:44,640 sites or the hp3 or the wts to see where 590 00:20:48,390 --> 00:20:46,640 we placed it and did we hit our target 591 00:20:50,549 --> 00:20:48,400 we wanted to practice our accuracy and 592 00:20:52,070 --> 00:20:50,559 precision and so using those cameras we 593 00:20:53,830 --> 00:20:52,080 were able to tell how close we got to 594 00:20:54,789 --> 00:20:53,840 our target spot and make tweaks as 595 00:20:56,070 --> 00:20:54,799 needed 596 00:20:58,070 --> 00:20:56,080 great and 597 00:21:00,789 --> 00:20:58,080 if anyone's watching they 598 00:21:02,470 --> 00:21:00,799 have a great insight on the inside 599 00:21:04,950 --> 00:21:02,480 lander and so you have any questions 600 00:21:07,270 --> 00:21:04,960 you'd like to ask use the ask nasa 601 00:21:09,990 --> 00:21:07,280 or leave your comments in the comment 602 00:21:13,510 --> 00:21:10,000 box below and questions as well so we 603 00:21:16,710 --> 00:21:13,520 have a couple other questions coming in 604 00:21:18,310 --> 00:21:16,720 uh let's see here 605 00:21:20,470 --> 00:21:18,320 um 606 00:21:23,029 --> 00:21:20,480 what oh we have some personal questions 607 00:21:25,029 --> 00:21:23,039 coming in what inspired both of you in 608 00:21:26,710 --> 00:21:25,039 your careers and what led you 609 00:21:29,590 --> 00:21:26,720 to nasa 610 00:21:32,390 --> 00:21:29,600 and sure so a couple things for me but 611 00:21:33,909 --> 00:21:32,400 one my cousin is an astrophysicist uh 612 00:21:36,149 --> 00:21:33,919 and so when i was young he would talk 613 00:21:38,149 --> 00:21:36,159 about the stars talk about space show me 614 00:21:39,669 --> 00:21:38,159 things through a telescope and when i 615 00:21:41,110 --> 00:21:39,679 would see those things he would study 616 00:21:42,470 --> 00:21:41,120 them behind the telescope and my first 617 00:21:44,470 --> 00:21:42,480 thought was why don't we go there and 618 00:21:46,870 --> 00:21:44,480 look at it and then that really sparked 619 00:21:48,789 --> 00:21:46,880 my interest in space exploration and 620 00:21:51,590 --> 00:21:48,799 since then i just wanted to be part of 621 00:21:53,270 --> 00:21:51,600 an organization which nasa is that helps 622 00:21:56,070 --> 00:21:53,280 go out into space and create new 623 00:21:58,310 --> 00:21:56,080 discoveries what about you mark yeah 624 00:22:01,669 --> 00:21:58,320 i'd say uh i got involved in this 625 00:22:03,350 --> 00:22:01,679 through a series of happy accidents um i 626 00:22:05,909 --> 00:22:03,360 don't think at any point in my life i 627 00:22:08,310 --> 00:22:05,919 planned on working for nasa it was never 628 00:22:10,630 --> 00:22:08,320 uh never the plan i 629 00:22:12,549 --> 00:22:10,640 ended up in college becoming a geology 630 00:22:14,630 --> 00:22:12,559 major because there was a class that let 631 00:22:17,430 --> 00:22:14,640 me go hiking in montana 632 00:22:19,510 --> 00:22:17,440 uh and and then i took more classes i 633 00:22:21,830 --> 00:22:19,520 was good at math so i started studying 634 00:22:23,029 --> 00:22:21,840 seismology which is geology plus math 635 00:22:23,909 --> 00:22:23,039 more or less 636 00:22:28,149 --> 00:22:23,919 um 637 00:22:29,510 --> 00:22:28,159 but i for uh grad school i focused on 638 00:22:30,950 --> 00:22:29,520 the earth 639 00:22:33,270 --> 00:22:30,960 but uh 640 00:22:37,350 --> 00:22:33,280 in order to stay in berkeley where i did 641 00:22:38,789 --> 00:22:37,360 my studies i got a project that involved 642 00:22:40,950 --> 00:22:38,799 thinking about what seismology would 643 00:22:43,590 --> 00:22:40,960 look like on europa which is a moon of 644 00:22:45,750 --> 00:22:43,600 jupiter um it was just somebody had a 645 00:22:47,909 --> 00:22:45,760 project i was like that sounds like fun 646 00:22:50,390 --> 00:22:47,919 and uh since then i've just been 647 00:22:53,750 --> 00:22:50,400 following opportunities like that um and 648 00:22:55,750 --> 00:22:53,760 some where along the line um uh the the 649 00:22:57,590 --> 00:22:55,760 lead of the mission uh principal 650 00:22:59,590 --> 00:22:57,600 investigator bruce banner uh talked to 651 00:23:01,430 --> 00:22:59,600 me and said we're thinking about doing 652 00:23:04,390 --> 00:23:01,440 seismology on mars would you like to be 653 00:23:07,590 --> 00:23:04,400 involved and i said yes with a big smile 654 00:23:10,310 --> 00:23:07,600 on my face and um now 655 00:23:12,149 --> 00:23:10,320 14 15 years later i'm still working on 656 00:23:14,149 --> 00:23:12,159 that project 657 00:23:15,590 --> 00:23:14,159 that's great and we have some questions 658 00:23:17,430 --> 00:23:15,600 coming in for you mark which we'll get 659 00:23:19,990 --> 00:23:17,440 to in a second but a lot of people are 660 00:23:23,990 --> 00:23:20,000 curious about the panels the solar 661 00:23:26,070 --> 00:23:24,000 panels can they be cleaned off on mars 662 00:23:28,710 --> 00:23:26,080 so insight itself does not have the 663 00:23:30,230 --> 00:23:28,720 capability of cleaning its solar panels 664 00:23:32,230 --> 00:23:30,240 if they do get cleaned it would be 665 00:23:34,230 --> 00:23:32,240 hopefully through one of the wind 666 00:23:36,230 --> 00:23:34,240 cleaning events that marx mentioned one 667 00:23:37,909 --> 00:23:36,240 of the questions that does get asked is 668 00:23:39,909 --> 00:23:37,919 why don't we have a way to clean our 669 00:23:42,310 --> 00:23:39,919 solar panels so 670 00:23:44,230 --> 00:23:42,320 the goal of insight is to collect the 671 00:23:45,510 --> 00:23:44,240 science data and meet answer the science 672 00:23:47,830 --> 00:23:45,520 questions that mark's discussed which 673 00:23:49,909 --> 00:23:47,840 we've done extremely well 674 00:23:51,990 --> 00:23:49,919 anytime you want to add more engineering 675 00:23:54,390 --> 00:23:52,000 complexities such as a way to clean 676 00:23:56,390 --> 00:23:54,400 solar panels we've incurred now we'll 677 00:23:57,990 --> 00:23:56,400 have new actuators new mechanisms we'll 678 00:23:59,590 --> 00:23:58,000 have to have a way to test it we'll have 679 00:24:00,950 --> 00:23:59,600 to have a way to make sure that it works 680 00:24:03,909 --> 00:24:00,960 we have to have a way to ensure that 681 00:24:05,909 --> 00:24:03,919 those items can't actually harm any of 682 00:24:08,070 --> 00:24:05,919 our science collection so our first 683 00:24:10,070 --> 00:24:08,080 priority is to ensure that anything we 684 00:24:11,430 --> 00:24:10,080 do we'll answer the science questions 685 00:24:13,190 --> 00:24:11,440 and make sure we bring our science data 686 00:24:14,630 --> 00:24:13,200 back and as mark mentioned the solar 687 00:24:16,070 --> 00:24:14,640 panels were sized so that they could 688 00:24:17,510 --> 00:24:16,080 meet the prime mission without requiring 689 00:24:19,269 --> 00:24:17,520 any cleaning 690 00:24:21,110 --> 00:24:19,279 and we're going to head back to the 691 00:24:23,350 --> 00:24:21,120 science questions we'll do our little 692 00:24:26,390 --> 00:24:23,360 dance with 693 00:24:30,470 --> 00:24:28,070 at this point 694 00:24:32,710 --> 00:24:30,480 it's fun to see so a few science 695 00:24:39,190 --> 00:24:32,720 questions coming in here has the lander 696 00:24:43,510 --> 00:24:41,110 on the scale of what people would think 697 00:24:45,510 --> 00:24:43,520 about as moving the answer is no 698 00:24:47,750 --> 00:24:45,520 it's been very stable 699 00:24:49,430 --> 00:24:47,760 people hear about big wind storms on 700 00:24:51,830 --> 00:24:49,440 mars and they do have very high 701 00:24:54,149 --> 00:24:51,840 velocities but the atmosphere is very 702 00:24:57,350 --> 00:24:54,159 very thin on mars 703 00:24:59,990 --> 00:24:57,360 it's about half a percent as dense as 704 00:25:01,669 --> 00:25:00,000 our atmosphere and so even when you have 705 00:25:03,750 --> 00:25:01,679 very strong winds it actually doesn't 706 00:25:06,390 --> 00:25:03,760 have that much force if you've seen the 707 00:25:07,990 --> 00:25:06,400 martian the beginning scene 708 00:25:10,230 --> 00:25:08,000 wouldn't happen on mars you wouldn't 709 00:25:12,630 --> 00:25:10,240 have enough energy to knock antennas 710 00:25:14,390 --> 00:25:12,640 over and do all of those things so 711 00:25:17,990 --> 00:25:14,400 hasn't moved 712 00:25:19,190 --> 00:25:18,000 on a large scale but um it does move on 713 00:25:21,430 --> 00:25:19,200 the very small scales that the 714 00:25:23,909 --> 00:25:21,440 seismometer can measure um as a matter 715 00:25:25,990 --> 00:25:23,919 of fact before we put ourselves down on 716 00:25:27,269 --> 00:25:26,000 the surface we were able to turn on one 717 00:25:29,590 --> 00:25:27,279 of the seismometers while it was still 718 00:25:31,830 --> 00:25:29,600 on the deck and we measured how much the 719 00:25:34,230 --> 00:25:31,840 lander moved in the wind and it actually 720 00:25:36,149 --> 00:25:34,240 moved in a measurable way back and forth 721 00:25:38,950 --> 00:25:36,159 very similar to how the viking landers 722 00:25:40,549 --> 00:25:38,960 moved which had seismometers on them but 723 00:25:42,070 --> 00:25:40,559 never got deployed down to the surface 724 00:25:44,710 --> 00:25:42,080 so they never saw mars quakes they just 725 00:25:46,230 --> 00:25:44,720 saw how the lander moved so 726 00:25:47,750 --> 00:25:46,240 that's all about how sensitive the 727 00:25:49,830 --> 00:25:47,760 seismometer is it can measure motions 728 00:25:52,870 --> 00:25:49,840 that are about the size of a hydrogen 729 00:25:55,909 --> 00:25:52,880 atom so very small motions can be seen 730 00:25:58,149 --> 00:25:55,919 but not to the point that you'd actually 731 00:26:00,149 --> 00:25:58,159 physically see the lander moving 732 00:26:02,549 --> 00:26:00,159 yeah that's quite the visual though to 733 00:26:04,549 --> 00:26:02,559 picture an atom moving and the next 734 00:26:06,789 --> 00:26:04,559 question is about temperature how hot 735 00:26:09,430 --> 00:26:06,799 are the temperatures during the day on 736 00:26:12,310 --> 00:26:09,440 mars and how cold does it get at night 737 00:26:14,310 --> 00:26:12,320 i i'm so um 738 00:26:17,190 --> 00:26:14,320 i don't want to answer that incorrectly 739 00:26:20,549 --> 00:26:17,200 okay so i it does get very cold i will 740 00:26:23,190 --> 00:26:20,559 say that we uh on in the warm 741 00:26:25,190 --> 00:26:23,200 electronics box on the inside of of 742 00:26:26,789 --> 00:26:25,200 insight which is inside there where you 743 00:26:27,990 --> 00:26:26,799 can't see it 744 00:26:29,669 --> 00:26:28,000 it's 745 00:26:31,830 --> 00:26:29,679 over time we've let it get colder than 746 00:26:34,390 --> 00:26:31,840 we initially designed for but now it 747 00:26:38,630 --> 00:26:34,400 gets down to temperatures of 748 00:26:40,549 --> 00:26:38,640 minus 35 celsius minus 38 celsius 749 00:26:42,390 --> 00:26:40,559 the surface gets much colder than that 750 00:26:43,909 --> 00:26:42,400 but i don't know the exact number so i 751 00:26:46,149 --> 00:26:43,919 don't want to say an incorrect number 752 00:26:48,870 --> 00:26:46,159 but it does get it does get quite chilly 753 00:26:50,789 --> 00:26:48,880 and during the day um it still is 754 00:26:53,430 --> 00:26:50,799 generally below zero degrees celsius so 755 00:26:55,990 --> 00:26:53,440 even on the balmiest summer days 756 00:26:58,549 --> 00:26:56,000 it's still very cold on mars no problem 757 00:27:01,190 --> 00:26:58,559 we can get you an answer in celsius and 758 00:27:04,549 --> 00:27:01,200 degrees at a later time but thanks that 759 00:27:07,909 --> 00:27:04,559 was a great question and then a question 760 00:27:08,710 --> 00:27:07,919 for both of you from sin city jim he 761 00:27:10,950 --> 00:27:08,720 says 762 00:27:14,149 --> 00:27:10,960 i know they're just machines but i get 763 00:27:15,590 --> 00:27:14,159 kind of sad when they come to an end 764 00:27:18,149 --> 00:27:15,600 it's almost like the death of a good 765 00:27:19,909 --> 00:27:18,159 friend do either of you feel that way 766 00:27:21,669 --> 00:27:19,919 when you think of a mission coming to an 767 00:27:23,909 --> 00:27:21,679 end i don't know who'd like to go first 768 00:27:25,909 --> 00:27:23,919 uh i absolutely feel that way insight 769 00:27:28,310 --> 00:27:25,919 was the first flight project i got to 770 00:27:32,230 --> 00:27:28,320 work on when i joined jpl i've been on 771 00:27:34,470 --> 00:27:32,240 it now for five and a half years uh 772 00:27:35,990 --> 00:27:34,480 i feel like insight's my friend uh i 773 00:27:38,070 --> 00:27:36,000 feel like every time insight makes a 774 00:27:39,750 --> 00:27:38,080 discovery or something amazing happens 775 00:27:41,750 --> 00:27:39,760 with insight i get excited the whole 776 00:27:44,070 --> 00:27:41,760 team gets excited uh whenever the 777 00:27:45,750 --> 00:27:44,080 mission does end i will be extremely sad 778 00:27:47,269 --> 00:27:45,760 but feel very fortunate and lucky to 779 00:27:48,549 --> 00:27:47,279 have worked on it 780 00:27:50,630 --> 00:27:48,559 yeah 781 00:27:52,230 --> 00:27:50,640 as i said in an answer to an earlier 782 00:27:55,750 --> 00:27:52,240 question i think i've been working on 783 00:27:58,149 --> 00:27:55,760 insight at for around 15 years now 784 00:27:59,750 --> 00:27:58,159 so this is a big part of my life 785 00:28:01,830 --> 00:27:59,760 it's been 786 00:28:03,990 --> 00:28:01,840 obviously something i'll always think 787 00:28:06,230 --> 00:28:04,000 about we had an earlier video where i 788 00:28:09,029 --> 00:28:06,240 showed my arm i don't know if i could do 789 00:28:12,789 --> 00:28:09,039 that here but there you go there's the 790 00:28:14,549 --> 00:28:12,799 the insight logo um so uh i will say 791 00:28:15,990 --> 00:28:14,559 that insights left a permanent mark on 792 00:28:16,710 --> 00:28:16,000 me 793 00:28:18,710 --> 00:28:16,720 and 794 00:28:20,710 --> 00:28:18,720 obviously when it ends it will be very 795 00:28:22,630 --> 00:28:20,720 sad but 796 00:28:24,630 --> 00:28:22,640 all things 797 00:28:25,990 --> 00:28:24,640 must pass as george harrison would say i 798 00:28:27,750 --> 00:28:26,000 guess 799 00:28:33,750 --> 00:28:27,760 i think a nice way to conclude it is 800 00:28:37,430 --> 00:28:35,909 that is a tough question to answer 801 00:28:39,590 --> 00:28:37,440 there's been a lot of 802 00:28:41,110 --> 00:28:39,600 good memories i think for me i spent 803 00:28:43,029 --> 00:28:41,120 most of my time working on insight in 804 00:28:45,750 --> 00:28:43,039 this room and as i mentioned we 805 00:28:47,990 --> 00:28:45,760 practiced all our deployments in here so 806 00:28:50,789 --> 00:28:48,000 i think really every time we got the 807 00:28:52,230 --> 00:28:50,799 seismometer to touch down we got the wts 808 00:28:54,230 --> 00:28:52,240 the wind and thermoshield on top of the 809 00:28:56,630 --> 00:28:54,240 seismometer we got the hp3 down each 810 00:28:58,389 --> 00:28:56,640 time those three events happened i felt 811 00:29:00,789 --> 00:28:58,399 elated it was just amazing that the 812 00:29:03,350 --> 00:29:00,799 things we tested in here so precisely we 813 00:29:04,310 --> 00:29:03,360 were able to do on mars successfully 814 00:29:06,310 --> 00:29:04,320 yeah i 815 00:29:09,430 --> 00:29:06,320 there's a million and so i i have a 816 00:29:12,950 --> 00:29:09,440 heart i i'll say probably the most 817 00:29:15,909 --> 00:29:12,960 overall intense experience so i 818 00:29:18,070 --> 00:29:15,919 started at jpl in 2017 just the year 819 00:29:20,230 --> 00:29:18,080 before we actually landed and then once 820 00:29:22,310 --> 00:29:20,240 we actually landed we 821 00:29:24,389 --> 00:29:22,320 for the next two and a half months while 822 00:29:25,510 --> 00:29:24,399 we were doing the deployment process it 823 00:29:28,070 --> 00:29:25,520 was 824 00:29:29,590 --> 00:29:28,080 all the time in sight we had meetings 825 00:29:31,269 --> 00:29:29,600 constantly and we were just talking 826 00:29:33,510 --> 00:29:31,279 through everything and it was just a 827 00:29:35,350 --> 00:29:33,520 very intense experience um in fact for 828 00:29:36,789 --> 00:29:35,360 the first week we were on mars time and 829 00:29:37,669 --> 00:29:36,799 i had to come in in the middle of the 830 00:29:38,470 --> 00:29:37,679 night 831 00:29:41,430 --> 00:29:38,480 and 832 00:29:43,669 --> 00:29:41,440 that was yeah that's that was like 833 00:29:45,510 --> 00:29:43,679 nothing else i guess 834 00:29:47,990 --> 00:29:45,520 what is mars time for people who might 835 00:29:49,669 --> 00:29:48,000 not know what that is um so basically 836 00:29:51,669 --> 00:29:49,679 the mars day 837 00:29:54,549 --> 00:29:51,679 is a little bit longer than the earth 838 00:29:55,990 --> 00:29:54,559 day um and 839 00:29:58,630 --> 00:29:56,000 when you're working and you're trying to 840 00:30:00,789 --> 00:29:58,640 do things on a quick pace you want to 841 00:30:03,669 --> 00:30:00,799 line up your work schedule to when we 842 00:30:04,470 --> 00:30:03,679 can communicate with the lander um and 843 00:30:06,789 --> 00:30:04,480 so 844 00:30:10,070 --> 00:30:06,799 that timing depends on time of day on 845 00:30:12,549 --> 00:30:10,080 mars not time of day on earth and so for 846 00:30:15,269 --> 00:30:12,559 the first week or so we 847 00:30:17,269 --> 00:30:15,279 timed our working shifts to be matching 848 00:30:19,029 --> 00:30:17,279 up with the uplink and downlink times on 849 00:30:21,029 --> 00:30:19,039 mars and that was shift a little bit 850 00:30:22,710 --> 00:30:21,039 each day about 40 minutes 851 00:30:24,470 --> 00:30:22,720 and it happened to be at that time of 852 00:30:26,549 --> 00:30:24,480 year it was kind of in the middle of the 853 00:30:27,669 --> 00:30:26,559 night so i got to see jpl in the middle 854 00:30:29,190 --> 00:30:27,679 of the night and there are crazy 855 00:30:30,310 --> 00:30:29,200 raccoons on lap in the middle of the 856 00:30:31,750 --> 00:30:30,320 night 857 00:30:33,909 --> 00:30:31,760 i don't think people know about all the 858 00:30:35,269 --> 00:30:33,919 critters that kind of move around here 859 00:30:36,870 --> 00:30:35,279 is there anything 860 00:30:37,909 --> 00:30:36,880 you'd like to say to your fellow team 861 00:30:39,830 --> 00:30:37,919 members 862 00:30:41,590 --> 00:30:39,840 as well um 863 00:30:43,110 --> 00:30:41,600 i just you know i really want to 864 00:30:46,549 --> 00:30:43,120 emphasize that 865 00:30:48,389 --> 00:30:46,559 this is a huge team effort um 866 00:30:50,470 --> 00:30:48,399 there are hundreds of people that have 867 00:30:52,310 --> 00:30:50,480 been involved in this and i cannot list 868 00:30:53,909 --> 00:30:52,320 them all we have 869 00:30:55,669 --> 00:30:53,919 hundreds of people on the science team 870 00:30:57,430 --> 00:30:55,679 that i'm dealing with directly we have 871 00:30:59,669 --> 00:30:57,440 hundreds of people on the operations 872 00:31:01,590 --> 00:30:59,679 team we have all of the people working 873 00:31:03,269 --> 00:31:01,600 here at the test bed and 874 00:31:05,350 --> 00:31:03,279 all of them were essential to make this 875 00:31:07,110 --> 00:31:05,360 happen there's no way we could do this 876 00:31:07,909 --> 00:31:07,120 without everybody working together and 877 00:31:10,710 --> 00:31:07,919 so 878 00:31:12,710 --> 00:31:10,720 everything that happens is 879 00:31:15,029 --> 00:31:12,720 just such a team effort and you know 880 00:31:17,350 --> 00:31:15,039 it's it's hard to imagine how much it 881 00:31:19,190 --> 00:31:17,360 depends on all of these different people 882 00:31:21,350 --> 00:31:19,200 yeah i want to just echo mark's comments 883 00:31:24,149 --> 00:31:21,360 there's a massive team of engineers 884 00:31:26,230 --> 00:31:24,159 scientists and others who made insight 885 00:31:27,509 --> 00:31:26,240 successful and i think the greatest joy 886 00:31:29,750 --> 00:31:27,519 we all have is we all got to work 887 00:31:32,470 --> 00:31:29,760 together on this this amazing mission 888 00:31:34,549 --> 00:31:32,480 and got to do something novel uh with 889 00:31:36,789 --> 00:31:34,559 the work we did yeah and it was nice to 890 00:31:38,789 --> 00:31:36,799 see you mentioned before 891 00:31:40,710 --> 00:31:38,799 visions come to life with the 892 00:31:42,549 --> 00:31:40,720 instruments that you put out together 893 00:31:44,070 --> 00:31:42,559 well that is all the time we have today 894 00:31:46,230 --> 00:31:44,080 thank you for your questions and thanks
