1 00:00:04,999 --> 00:00:03,500 how does it feel it feels great hi my 2 00:00:06,619 --> 00:00:05,009 name is Heather bottom and I'm helping 3 00:00:08,330 --> 00:00:06,629 prepare the spacecraft that will fly our 4 00:00:11,419 --> 00:00:08,340 next Mars rover to the Martian surface 5 00:00:13,549 --> 00:00:11,429 so here we have the rover test facility 6 00:00:17,599 --> 00:00:13,559 for the Mars 2020 project so the goal of 7 00:00:19,939 --> 00:00:17,609 Mars 2020 is to collect samples of the 8 00:00:22,340 --> 00:00:19,949 surface of Mars and perform lots of 9 00:00:23,990 --> 00:00:22,350 other exciting experiments there's seven 10 00:00:25,790 --> 00:00:24,000 different instruments on the rover some 11 00:00:28,189 --> 00:00:25,800 of the work that's being done here right 12 00:00:30,109 --> 00:00:28,199 now is integrating the arm and the mast 13 00:00:31,999 --> 00:00:30,119 my role is mostly on the systems 14 00:00:33,830 --> 00:00:32,009 engineering of the launch and cruise 15 00:00:35,990 --> 00:00:33,840 phases of the mission is essentially 16 00:00:37,400 --> 00:00:36,000 getting it to Mars as a systems engineer 17 00:00:38,869 --> 00:00:37,410 you kind of have to put those different 18 00:00:41,090 --> 00:00:38,879 pieces together and make sure that those 19 00:00:43,100 --> 00:00:41,100 pieces all are gonna work you get to 20 00:00:44,569 --> 00:00:43,110 kind of see the bigger picture before 21 00:00:45,650 --> 00:00:44,579 the rover actually flies you have to 22 00:00:47,630 --> 00:00:45,660 make sure that everything works properly 23 00:00:50,119 --> 00:00:47,640 with the flight software and the 24 00:00:52,040 --> 00:00:50,129 hardware so I have a little unique story 25 00:00:54,020 --> 00:00:52,050 I actually ended up becoming a 26 00:00:55,670 --> 00:00:54,030 professional dancer in New York and I 27 00:00:57,380 --> 00:00:55,680 really like lived that out so its 28 00:00:59,060 --> 00:00:57,390 fullest and where all the makeup the 29 00:01:00,650 --> 00:00:59,070 rhinestones and things but for some 30 00:01:02,510 --> 00:01:00,660 reason I I always knew I was going to 31 00:01:05,030 --> 00:01:02,520 come back to this kind of curiosity that 32 00:01:06,740 --> 00:01:05,040 I've always had with space there's some 33 00:01:09,440 --> 00:01:06,750 of that creativity here too 34 00:01:11,179 --> 00:01:09,450 sometimes I feel like we're kind of like 35 00:01:12,859 --> 00:01:11,189 the stagehands in this big production 36 00:01:14,270 --> 00:01:12,869 for the rover it's bringing together a 37 00:01:15,620 --> 00:01:14,280 bunch of people it's making sure that 38 00:01:17,240 --> 00:01:15,630 the hardware works and it's kind of 39 00:01:19,370 --> 00:01:17,250 similar to a performance or like on 40 00:01:24,670 --> 00:01:19,380 launch day it'll be the opening night 41 00:01:30,230 --> 00:01:28,160 hi I'm Kevin Weaver with NASA's Jet 42 00:01:33,440 --> 00:01:30,240 Propulsion Laboratory in Southern 43 00:01:35,990 --> 00:01:33,450 California JPL is where the Mars 2020 44 00:01:39,050 --> 00:01:36,000 mission and perseverance Rover are 45 00:01:42,290 --> 00:01:39,060 managed getting to Mars is a test of 46 00:01:45,290 --> 00:01:42,300 perseverance in itself there are so many 47 00:01:47,420 --> 00:01:45,300 incredible stories from the thousands of 48 00:01:49,850 --> 00:01:47,430 people who are part of the mission today 49 00:01:51,020 --> 00:01:49,860 we're with one of the many faces behind 50 00:01:54,200 --> 00:01:51,030 the spacecraft 51 00:01:57,080 --> 00:01:54,210 Heather bottom is a systems engineer for 52 00:01:58,969 --> 00:01:57,090 the Mars 2020 mission which means she is 53 00:02:00,230 --> 00:01:58,979 making sure all the pieces work together 54 00:02:02,240 --> 00:02:00,240 on the spacecraft 55 00:02:03,980 --> 00:02:02,250 Heather's journey to testing Rockets 56 00:02:06,320 --> 00:02:03,990 actually started with a career in the 57 00:02:08,540 --> 00:02:06,330 arts including dancing for the Rockettes 58 00:02:11,480 --> 00:02:08,550 she joins us from her home today to 59 00:02:13,370 --> 00:02:11,490 answer questions and if you have any 60 00:02:14,930 --> 00:02:13,380 questions you'd like to ask you can 61 00:02:18,290 --> 00:02:14,940 leave them right here in the YouTube 62 00:02:21,380 --> 00:02:18,300 chat or post them to social media using 63 00:02:23,330 --> 00:02:21,390 the hashtag ask NASA now if you're on 64 00:02:25,250 --> 00:02:23,340 youtube and can't see the questions or 65 00:02:27,199 --> 00:02:25,260 the chat room yet just refresh your 66 00:02:30,940 --> 00:02:27,209 browser and it should all be there and 67 00:02:33,800 --> 00:02:30,950 Heather thanks for talking to us today 68 00:02:34,660 --> 00:02:33,810 Thanks thanks for having me yeah this'll 69 00:02:37,910 --> 00:02:34,670 be great 70 00:02:40,310 --> 00:02:37,920 I'm great so to start off as a systems 71 00:02:42,770 --> 00:02:40,320 engineer your focus is on the bigger 72 00:02:46,570 --> 00:02:42,780 picture can you describe what you're 73 00:02:52,130 --> 00:02:49,580 absolutely so I'm one of the launch 74 00:02:55,280 --> 00:02:52,140 systems engineers so we're preparing the 75 00:02:58,250 --> 00:02:55,290 vehicle for launch day on hopefully on 76 00:03:00,020 --> 00:02:58,260 July 17th which means preparing all of 77 00:03:01,400 --> 00:03:00,030 the different files and sequences that 78 00:03:04,370 --> 00:03:01,410 you need to have onboard for the 79 00:03:06,170 --> 00:03:04,380 spacecraft in my it means preparing the 80 00:03:08,680 --> 00:03:06,180 procedures that you're going to need for 81 00:03:11,060 --> 00:03:08,690 launch day as well as after launch day 82 00:03:13,280 --> 00:03:11,070 so there's a plenty of things that are 83 00:03:13,940 --> 00:03:13,290 going on in preparation for launch but 84 00:03:16,030 --> 00:03:13,950 in parallel 85 00:03:18,920 --> 00:03:16,040 we're also orchestrating a number of 86 00:03:21,320 --> 00:03:18,930 system level tests scenario tests day in 87 00:03:23,390 --> 00:03:21,330 the life sort of scenarios where we 88 00:03:25,400 --> 00:03:23,400 bring all three different stages of the 89 00:03:27,860 --> 00:03:25,410 vehicle together so we have the crew 90 00:03:29,570 --> 00:03:27,870 stage that's going to get us to Mars the 91 00:03:31,150 --> 00:03:29,580 defense stage that helps us get to the 92 00:03:34,000 --> 00:03:31,160 surface of Mars I'm 93 00:03:35,590 --> 00:03:34,010 the rover which obviously is performing 94 00:03:37,930 --> 00:03:35,600 all the science that we wanted to on the 95 00:03:40,360 --> 00:03:37,940 surface so by integrating all three of 96 00:03:42,100 --> 00:03:40,370 those stages together we perform the 97 00:03:44,050 --> 00:03:42,110 scenario tests where we simulate the 98 00:03:46,780 --> 00:03:44,060 actual flight hardware with the flight 99 00:03:48,400 --> 00:03:46,790 software launching traveling through 100 00:03:50,830 --> 00:03:48,410 space and then landing on Mars and 101 00:03:52,300 --> 00:03:50,840 performing some surface operation so for 102 00:03:55,090 --> 00:03:52,310 the last few years we've been really 103 00:03:57,430 --> 00:03:55,100 focused on the series of tests and 104 00:03:58,990 --> 00:03:57,440 really the unit under test there has 105 00:04:00,910 --> 00:03:59,000 been the flight hardware and a flight 106 00:04:04,060 --> 00:04:00,920 software and most recently we've started 107 00:04:06,040 --> 00:04:04,070 bringing in now the operators so people 108 00:04:09,130 --> 00:04:06,050 like myself and the flight team the 109 00:04:11,860 --> 00:04:09,140 operating team who then come in and 110 00:04:15,220 --> 00:04:11,870 we're now tested and so we go through a 111 00:04:20,140 --> 00:04:15,230 series of tests for launch I'm in regard 112 00:04:22,780 --> 00:04:20,150 to oh we seem to have lost a connection 113 00:04:25,300 --> 00:04:22,790 a little bit so I will kind of ask it 114 00:04:26,770 --> 00:04:25,310 again and see if you can hear me what 115 00:04:31,690 --> 00:04:26,780 was that last part that you said again 116 00:04:33,700 --> 00:04:31,700 oh um what we so yeah so we're going 117 00:04:39,610 --> 00:04:33,710 through a series of scenario tests did 118 00:04:41,920 --> 00:04:39,620 you get that part maybe um yeah so the 119 00:04:44,170 --> 00:04:41,930 scenario places that we perform simulate 120 00:04:46,060 --> 00:04:44,180 the vehicle launching traveling through 121 00:04:49,600 --> 00:04:46,070 space and then landing on the surface of 122 00:04:51,850 --> 00:04:49,610 Mars and then obviously performing some 123 00:04:54,010 --> 00:04:51,860 surface activities as well so once we go 124 00:04:56,620 --> 00:04:54,020 through those series of tests now we've 125 00:04:58,480 --> 00:04:56,630 added in the operators themselves like 126 00:05:00,670 --> 00:04:58,490 myself and the rest of the flight team 127 00:05:02,740 --> 00:05:00,680 the operating team and so we're working 128 00:05:05,170 --> 00:05:02,750 now on a series of tests where it 129 00:05:06,970 --> 00:05:05,180 includes the operators as well and we'll 130 00:05:12,090 --> 00:05:06,980 continue doing these tests as we get 131 00:05:15,340 --> 00:05:12,100 towards the launch window okay great and 132 00:05:19,180 --> 00:05:15,350 what I was gonna ask oh do you even keep 133 00:05:23,530 --> 00:05:19,190 the test going after launch oh yes 134 00:05:25,180 --> 00:05:23,540 absolutely um so the launch team really 135 00:05:27,610 --> 00:05:25,190 obviously our cutoff date is gonna be 136 00:05:30,070 --> 00:05:27,620 launch but we have six months until we 137 00:05:32,290 --> 00:05:30,080 get to Mars so there's a whole series of 138 00:05:34,600 --> 00:05:32,300 entry descent and landing testing that 139 00:05:36,520 --> 00:05:34,610 happens over those six months also 140 00:05:38,590 --> 00:05:36,530 including the operators making sure that 141 00:05:40,810 --> 00:05:38,600 the operators are all ready to support 142 00:05:43,480 --> 00:05:40,820 and then of course there is the surface 143 00:05:44,620 --> 00:05:43,490 series of tests that are still being 144 00:05:46,630 --> 00:05:44,630 performed during those 145 00:05:48,640 --> 00:05:46,640 six months and so part of the planning 146 00:05:50,410 --> 00:05:48,650 process is identifying what do we 147 00:05:51,880 --> 00:05:50,420 absolutely have to do before we launch 148 00:05:54,580 --> 00:05:51,890 what's the bare minimum and then what 149 00:05:56,110 --> 00:05:54,590 can we push off for those six months to 150 00:06:01,390 --> 00:05:56,120 buy us a little bit of time for some of 151 00:06:04,090 --> 00:06:01,400 those preparations great and then we 152 00:06:06,640 --> 00:06:04,100 kind of got into the name perseverance 153 00:06:08,350 --> 00:06:06,650 and all the testing that really lives up 154 00:06:13,110 --> 00:06:08,360 to its name what are your personal 155 00:06:15,400 --> 00:06:13,120 thought a name oh gosh um well 156 00:06:19,030 --> 00:06:15,410 perseverance is so much more than a name 157 00:06:22,360 --> 00:06:19,040 I guess for the launch team we've really 158 00:06:22,870 --> 00:06:22,370 felt this this drive toward the launch 159 00:06:25,510 --> 00:06:22,880 window 160 00:06:28,570 --> 00:06:25,520 July 17th is when it opens and might 161 00:06:30,220 --> 00:06:28,580 last until about the end of August and 162 00:06:31,570 --> 00:06:30,230 if you don't make it in that launch 163 00:06:33,400 --> 00:06:31,580 window if you don't launch within that 164 00:06:36,130 --> 00:06:33,410 time we'll have to wait another two 165 00:06:38,530 --> 00:06:36,140 years before Earth and Mars alignment 166 00:06:40,900 --> 00:06:38,540 will be appropriate for us to actually 167 00:06:43,000 --> 00:06:40,910 get to Mars so I think our team is 168 00:06:46,360 --> 00:06:43,010 definitely persevering toward that that 169 00:06:49,780 --> 00:06:46,370 deadline and certainly I feel the 170 00:06:51,820 --> 00:06:49,790 pressure there but then you know 171 00:06:55,120 --> 00:06:51,830 perseverance is held in so many other 172 00:06:59,170 --> 00:06:55,130 ways for our team and any other teams as 173 00:07:01,480 --> 00:06:59,180 well that's great and another thing I 174 00:07:04,270 --> 00:07:01,490 really wanted to ask you about is your 175 00:07:07,060 --> 00:07:04,280 career being a mix of art and science 176 00:07:11,230 --> 00:07:07,070 can you talk about your journey and how 177 00:07:12,040 --> 00:07:11,240 you got to be here at JPL yeah 178 00:07:14,530 --> 00:07:12,050 absolutely 179 00:07:17,170 --> 00:07:14,540 um so ever since I was little I always 180 00:07:18,640 --> 00:07:17,180 enjoyed dancing and performing so I've 181 00:07:20,920 --> 00:07:18,650 always kind of kept that with me as 182 00:07:22,990 --> 00:07:20,930 times gone on but when I was younger I 183 00:07:26,530 --> 00:07:23,000 found a real love for astronomy 184 00:07:29,920 --> 00:07:26,540 so I major in college undergrad in 185 00:07:31,540 --> 00:07:29,930 astronomy and then after college there 186 00:07:33,550 --> 00:07:31,550 actually excuse me through college I 187 00:07:35,530 --> 00:07:33,560 took an internship with the NASA Ames 188 00:07:37,630 --> 00:07:35,540 Research Center it was called the NASA 189 00:07:40,450 --> 00:07:37,640 Academy at the time not sure if it's 190 00:07:42,879 --> 00:07:40,460 still called that and through the NASA 191 00:07:44,320 --> 00:07:42,889 it really opened up my eyes not just to 192 00:07:47,529 --> 00:07:44,330 astronomy but to this whole space 193 00:07:48,939 --> 00:07:47,539 industry not just NASA but that also the 194 00:07:51,249 --> 00:07:48,949 commercial space industry that's 195 00:07:53,860 --> 00:07:51,259 happening right now but SpaceX sons of 196 00:07:55,749 --> 00:07:53,870 origin so do that internship it showed 197 00:07:57,820 --> 00:07:55,759 me there was so much more and so I told 198 00:07:59,559 --> 00:07:57,830 myself at the time I knew no matter how 199 00:08:02,140 --> 00:07:59,569 much dance I pursued I would always come 200 00:08:06,700 --> 00:08:02,150 back to space and I think I think I say 201 00:08:09,100 --> 00:08:06,710 that in the video too but yeah so you 202 00:08:12,700 --> 00:08:09,110 know so I went and pursued dance um I 203 00:08:14,529 --> 00:08:12,710 was when I was indeed or really hard so 204 00:08:17,170 --> 00:08:14,539 I did the Rockettes and I did a show 205 00:08:18,700 --> 00:08:17,180 called A Chorus Line at the time and I 206 00:08:21,610 --> 00:08:18,710 hit a point where I said okay it's time 207 00:08:24,820 --> 00:08:21,620 to go back so I had learned about 208 00:08:27,460 --> 00:08:24,830 engineering so I went back to school I 209 00:08:31,629 --> 00:08:27,470 Caltech in Pasadena for aerospace 210 00:08:34,750 --> 00:08:31,639 engineering and I started to learn that 211 00:08:37,570 --> 00:08:34,760 I really loved this big picture idea and 212 00:08:39,909 --> 00:08:37,580 I took a job in systems engineering at 213 00:08:41,740 --> 00:08:39,919 SpaceX and so when I was at SpaceX I 214 00:08:43,300 --> 00:08:41,750 learned about systems engineering and 215 00:08:46,060 --> 00:08:43,310 how important that is to the spacecraft 216 00:08:47,500 --> 00:08:46,070 into the whole mission it felt like it 217 00:08:49,199 --> 00:08:47,510 really hit home for me that was 218 00:08:52,510 --> 00:08:49,209 something that I could really relate to 219 00:08:54,940 --> 00:08:52,520 and so then do friends and resume 220 00:08:57,220 --> 00:08:54,950 passing around things I ended up by JPL 221 00:09:01,720 --> 00:08:57,230 eventually but those are kind of the 222 00:09:03,550 --> 00:09:01,730 journey of how I got there and for 223 00:09:06,160 --> 00:09:03,560 anyone watching who really has a passion 224 00:09:08,050 --> 00:09:06,170 for science and art like you do what 225 00:09:09,699 --> 00:09:08,060 advice would you give them when they're 226 00:09:13,900 --> 00:09:09,709 kind of trying to decide their career 227 00:09:17,470 --> 00:09:13,910 path and how to balance both oh gosh um 228 00:09:21,550 --> 00:09:17,480 so I guess to never like give up on 229 00:09:23,620 --> 00:09:21,560 either I think what I found is I had to 230 00:09:26,440 --> 00:09:23,630 maintain and find a balance as I've 231 00:09:28,420 --> 00:09:26,450 gotten older so every time I find that 232 00:09:31,240 --> 00:09:28,430 I've gone without dance or singing for a 233 00:09:34,269 --> 00:09:31,250 while I kind of get sad and I need to 234 00:09:35,560 --> 00:09:34,279 find a dance class to take or I'll sing 235 00:09:37,690 --> 00:09:35,570 at home with my husband there's 236 00:09:40,480 --> 00:09:37,700 something like that and equally when I 237 00:09:43,360 --> 00:09:40,490 had pursued dance so hard for so long I 238 00:09:45,040 --> 00:09:43,370 really found that I missed research and 239 00:09:48,100 --> 00:09:45,050 I missed learning about space and my 240 00:09:48,650 --> 00:09:48,110 passion for space and so as I've gotten 241 00:09:50,119 --> 00:09:48,660 older 242 00:09:51,590 --> 00:09:50,129 you can't let one of the other really 243 00:09:54,559 --> 00:09:51,600 take over and so you really have to 244 00:09:58,400 --> 00:09:54,569 maintain that balance so just never give 245 00:10:00,319 --> 00:09:58,410 up on that and I guess there's something 246 00:10:03,680 --> 00:10:00,329 else I was gonna say along his lines but 247 00:10:05,360 --> 00:10:03,690 what we'll get back to anyway all right 248 00:10:07,040 --> 00:10:05,370 because those were all my questions and 249 00:10:09,079 --> 00:10:07,050 if you get back to and remember just let 250 00:10:12,139 --> 00:10:09,089 me know I'm gonna get now to the ask 251 00:10:12,949 --> 00:10:12,149 NASA questions and see what people have 252 00:10:15,490 --> 00:10:12,959 to say so 253 00:10:18,350 --> 00:10:15,500 Martian Manisha on Twitter asks how is 254 00:10:23,329 --> 00:10:18,360 engineering for Mars different from 255 00:10:25,819 --> 00:10:23,339 engineering for Earth oh gosh um so this 256 00:10:28,220 --> 00:10:25,829 is a fun question I recently had some 257 00:10:30,829 --> 00:10:28,230 discussions raised some astronomers so 258 00:10:32,720 --> 00:10:30,839 astronomers have tells gotiya better on 259 00:10:34,579 --> 00:10:32,730 the ground and you can access them at 260 00:10:35,929 --> 00:10:34,589 any time and as I was talking to these 261 00:10:37,819 --> 00:10:35,939 astronomers that are saying yeah you 262 00:10:39,170 --> 00:10:37,829 know if we run into issues you just go 263 00:10:41,150 --> 00:10:39,180 up to the telescope any fix the 264 00:10:42,920 --> 00:10:41,160 telescope I'm thinking to myself it 265 00:10:45,559 --> 00:10:42,930 actually took me some time to realize oh 266 00:10:47,179 --> 00:10:45,569 you can just go touch the hardware and 267 00:10:49,280 --> 00:10:47,189 fix it like if you have a problem you 268 00:10:51,170 --> 00:10:49,290 know that's part of your your project 269 00:10:52,850 --> 00:10:51,180 that's just how it works like when you 270 00:10:54,379 --> 00:10:52,860 can send things up to space you you 271 00:10:56,329 --> 00:10:54,389 don't get to touch it anymore once it's 272 00:10:59,210 --> 00:10:56,339 up there so if you have to consider all 273 00:11:00,980 --> 00:10:59,220 the different anomalies and hardware 274 00:11:02,660 --> 00:11:00,990 issues that you could run into before 275 00:11:04,009 --> 00:11:02,670 you send those things up into space and 276 00:11:06,290 --> 00:11:04,019 that's part of this whole test campaign 277 00:11:08,300 --> 00:11:06,300 that we go through and so there's I 278 00:11:10,639 --> 00:11:08,310 think that distinct difference in your 279 00:11:12,679 --> 00:11:10,649 prepping and your planning and your 280 00:11:14,809 --> 00:11:12,689 preparation to make sure that you 281 00:11:16,309 --> 00:11:14,819 include consideration of the fact you 282 00:11:19,309 --> 00:11:16,319 won't be able to touch it anymore 283 00:11:21,259 --> 00:11:19,319 once it gets up there so that means you 284 00:11:24,160 --> 00:11:21,269 almost have to think of every single 285 00:11:28,309 --> 00:11:24,170 thing that could go wrong correct 286 00:11:30,470 --> 00:11:28,319 yeah they I guess the term I've heard 287 00:11:33,559 --> 00:11:30,480 passed around is unknown unknowns so 288 00:11:34,999 --> 00:11:33,569 there's always this small bit that you 289 00:11:37,519 --> 00:11:35,009 keep in the back of your mind with gosh 290 00:11:38,840 --> 00:11:37,529 there are certainly many unknown 291 00:11:42,290 --> 00:11:38,850 unknowns that we haven't thought about 292 00:11:44,059 --> 00:11:42,300 but yes as part of our team for every 293 00:11:45,769 --> 00:11:44,069 agents we're trying to figure out any 294 00:11:47,780 --> 00:11:45,779 different thing we can come up with and 295 00:11:50,420 --> 00:11:47,790 that's part of some of the testing that 296 00:11:53,530 --> 00:11:50,430 we're doing and if certainly if 297 00:11:56,360 --> 00:11:53,540 something does go wrong up in space and 298 00:11:58,759 --> 00:11:56,370 the vehicle doesn't autonomously react 299 00:11:59,660 --> 00:11:58,769 to it then you do have glad operators 300 00:12:02,600 --> 00:11:59,670 come in 301 00:12:04,400 --> 00:12:02,610 command the vehicle and try to get it 302 00:12:07,090 --> 00:12:04,410 back in the state that you at least a 303 00:12:10,040 --> 00:12:07,100 healthy state to get you to Mars 304 00:12:12,320 --> 00:12:10,050 recently in one of our anomalous 305 00:12:15,890 --> 00:12:12,330 operations test that just completed it 306 00:12:18,050 --> 00:12:15,900 was a pretty intense 48 hours we weren't 307 00:12:20,450 --> 00:12:18,060 able to even command the vehicle and so 308 00:12:22,160 --> 00:12:20,460 we had to think through the situation of 309 00:12:25,540 --> 00:12:22,170 what you would do and how you would fix 310 00:12:28,010 --> 00:12:25,550 it and so we went through a series of 311 00:12:29,990 --> 00:12:28,020 differents recoveries that we could do 312 00:12:33,680 --> 00:12:30,000 in order to commander me we eventually 313 00:12:36,650 --> 00:12:33,690 got through it someone and I actually 314 00:12:39,710 --> 00:12:36,660 have another one from Florentin sitters 315 00:12:41,630 --> 00:12:39,720 on YouTube who asks kind of how does the 316 00:12:44,450 --> 00:12:41,640 team decide between the scientific 317 00:12:46,250 --> 00:12:44,460 benefits of certain features compared to 318 00:12:50,630 --> 00:12:46,260 the challenges these pose from an 319 00:12:52,880 --> 00:12:50,640 engineering standpoint that's a really 320 00:13:06,200 --> 00:12:52,890 great question I'm sorry I have a 321 00:13:08,630 --> 00:13:06,210 chicken here some part yeah so it's 322 00:13:10,910 --> 00:13:08,640 definitely a trade so with systems 323 00:13:12,350 --> 00:13:10,920 engineering one of those interesting 324 00:13:14,350 --> 00:13:12,360 parts I don't think people know about 325 00:13:16,910 --> 00:13:14,360 when they sign up for the job level but 326 00:13:20,060 --> 00:13:16,920 you're not just an engineer but you kind 327 00:13:22,370 --> 00:13:20,070 of become a bit of a negotiator so you 328 00:13:24,260 --> 00:13:22,380 have to really understand both sides of 329 00:13:27,530 --> 00:13:24,270 the argument and being able to consider 330 00:13:30,350 --> 00:13:27,540 the risks for both of the trades so that 331 00:13:32,870 --> 00:13:30,360 you can come up with not the 100% 332 00:13:35,480 --> 00:13:32,880 solution but maybe the best solution you 333 00:13:38,510 --> 00:13:35,490 can come up with at the time so I think 334 00:13:40,670 --> 00:13:38,520 a lot of engineers didn't think in like 335 00:13:42,440 --> 00:13:40,680 a black and white space but as a systems 336 00:13:45,320 --> 00:13:42,450 engineer I feel like I'm constantly in a 337 00:13:47,330 --> 00:13:45,330 gray space when trying to understand how 338 00:13:49,820 --> 00:13:47,340 great this is how black need to be a 339 00:13:52,280 --> 00:13:49,830 white we need to be and then you know 340 00:13:54,470 --> 00:13:52,290 talking in depth to these experts to 341 00:13:56,330 --> 00:13:54,480 really know to really know what they 342 00:13:58,220 --> 00:13:56,340 know what to understand what I don't 343 00:14:00,680 --> 00:13:58,230 know because obviously there's plenty I 344 00:14:02,000 --> 00:14:00,690 don't know and and to be able to get to 345 00:14:05,780 --> 00:14:02,010 a place where you can come up with the 346 00:14:08,530 --> 00:14:05,790 best solution for the mission and then I 347 00:14:10,090 --> 00:14:08,540 have another question from Ahmad Homer 348 00:14:12,550 --> 00:14:10,100 I don't know if you know this but how 349 00:14:17,980 --> 00:14:12,560 long do we expect perseverance to last 350 00:14:20,710 --> 00:14:17,990 on Mars oh gosh I don't want to get it 351 00:14:23,340 --> 00:14:20,720 wrong I think it's about one Martian 352 00:14:26,400 --> 00:14:23,350 year which is equivalent to about a year 353 00:14:29,710 --> 00:14:26,410 unlike a handful of months here on earth 354 00:14:31,120 --> 00:14:29,720 something like that but I'm not always 355 00:14:35,350 --> 00:14:31,130 there this team so I don't know the 356 00:14:37,120 --> 00:14:35,360 details about the way so am i you can 357 00:14:39,520 --> 00:14:37,130 also ask that question to ask NASA 358 00:14:43,180 --> 00:14:39,530 persevere or we can get back to you with 359 00:14:45,010 --> 00:14:43,190 an answer on that and he also wants to 360 00:14:50,890 --> 00:14:45,020 know is there any artificial 361 00:14:54,220 --> 00:14:50,900 intelligence on perseverance well so 362 00:14:55,750 --> 00:14:54,230 anyway I think you defined in many 363 00:14:57,790 --> 00:14:55,760 different ways I think one of the 364 00:15:01,120 --> 00:14:57,800 coolest things about this Rover is that 365 00:15:05,380 --> 00:15:01,130 it has an ability to navigate with a 366 00:15:07,720 --> 00:15:05,390 better time escape abilities than the 367 00:15:10,000 --> 00:15:07,730 previous Rovers and curiosity so it's 368 00:15:12,310 --> 00:15:10,010 able to identify different rocks and 369 00:15:15,280 --> 00:15:12,320 move around those rocks that sort of 370 00:15:18,130 --> 00:15:15,290 thing I think that's like the biggest 371 00:15:21,670 --> 00:15:18,140 improvement to AI that we have on the 372 00:15:23,500 --> 00:15:21,680 beautiful for 2020 compared to curiosity 373 00:15:25,450 --> 00:15:23,510 but there's certainly a lot of things 374 00:15:28,630 --> 00:15:25,460 that we've developed a high-rise for all 375 00:15:31,960 --> 00:15:28,640 the Rovers but I would say it depends on 376 00:15:34,960 --> 00:15:31,970 your definition I think a little bit and 377 00:15:37,240 --> 00:15:34,970 another thing that would be new on here 378 00:15:39,460 --> 00:15:37,250 Fletcher on YouTube asks how do you 379 00:15:41,410 --> 00:15:39,470 select the cameras and their angles for 380 00:15:46,420 --> 00:15:41,420 the rover and is a difference for 381 00:15:47,350 --> 00:15:46,430 science versus engineering cameras yeah 382 00:15:49,300 --> 00:15:47,360 absolutely 383 00:15:51,900 --> 00:15:49,310 there are different engineering cameras 384 00:15:53,400 --> 00:15:51,910 I'm dedicated strictly to engineering 385 00:15:55,810 --> 00:15:53,410 hazards 386 00:15:59,680 --> 00:15:55,820 they're called bajas cams on the rover 387 00:16:02,050 --> 00:15:59,690 and then the yet the math comes as well 388 00:16:03,520 --> 00:16:02,060 I will obligation camera and then each 389 00:16:04,660 --> 00:16:03,530 of the instruments not each of the 390 00:16:07,390 --> 00:16:04,670 instruments but many of the instruments 391 00:16:09,730 --> 00:16:07,400 have cameras themselves that are higher 392 00:16:12,160 --> 00:16:09,740 resolution and those sorts of things but 393 00:16:14,080 --> 00:16:12,170 you need to consider the different 394 00:16:18,280 --> 00:16:14,090 resources that those cameras are taking 395 00:16:22,840 --> 00:16:18,290 up onboard so power data 396 00:16:24,550 --> 00:16:22,850 the thermal anything like that just to 397 00:16:26,530 --> 00:16:24,560 consider how much fam that those things 398 00:16:29,050 --> 00:16:26,540 are taking up and so again it becomes a 399 00:16:30,639 --> 00:16:29,060 trade between while which science 400 00:16:31,960 --> 00:16:30,649 objectives are more important to make 401 00:16:34,480 --> 00:16:31,970 sure that we're not in a hazardous 402 00:16:36,040 --> 00:16:34,490 situation with the roller but the 403 00:16:38,860 --> 00:16:36,050 different in terms of the different 404 00:16:41,139 --> 00:16:38,870 angles there are designs so that there 405 00:16:44,129 --> 00:16:41,149 for science specifically or for 406 00:16:48,220 --> 00:16:44,139 engineering purposes specifically and 407 00:16:51,160 --> 00:16:48,230 then give you my toe asks how do you 408 00:16:54,160 --> 00:16:51,170 protect the circuit boards from flips 409 00:16:58,780 --> 00:16:54,170 due to radiation from bit flips due to 410 00:17:02,829 --> 00:16:58,790 radiation I probably not the expert on 411 00:17:05,919 --> 00:17:02,839 on radiation protection but I do know 412 00:17:09,939 --> 00:17:05,929 it's on board so again we'll defer that 413 00:17:11,530 --> 00:17:09,949 to the asknasa hashtag and go to @nasa 414 00:17:14,470 --> 00:17:11,540 persevere and we'll try to get you an 415 00:17:16,960 --> 00:17:14,480 answer on that so Florian on YouTube 416 00:17:23,079 --> 00:17:16,970 asks how does perseverance Rovers team 417 00:17:27,069 --> 00:17:23,089 balance decisions ah so it's a really 418 00:17:31,000 --> 00:17:27,079 good question so a lot of the team comes 419 00:17:34,030 --> 00:17:31,010 from the curiosity Mars rover team and 420 00:17:36,730 --> 00:17:34,040 so what we found is that there's a 421 00:17:39,370 --> 00:17:36,740 balance constantly between how things 422 00:17:41,850 --> 00:17:39,380 were done on curiosity and how we wanna 423 00:17:44,919 --> 00:17:41,860 make things better for Mars 2020 um 424 00:17:47,640 --> 00:17:44,929 without adding additional risk so I 425 00:17:50,140 --> 00:17:47,650 think there's a really fine line between 426 00:17:52,600 --> 00:17:50,150 making things new and fancy for the sake 427 00:17:55,690 --> 00:17:52,610 of making them too fancy and using this 428 00:17:58,390 --> 00:17:55,700 heritage because you know that it's a 429 00:18:01,030 --> 00:17:58,400 heritage design what works and of course 430 00:18:05,820 --> 00:18:01,040 even with that there's a risk that maybe 431 00:18:08,140 --> 00:18:05,830 the design that worked was some sort of 432 00:18:11,440 --> 00:18:08,150 negative negative or positive positive 433 00:18:13,539 --> 00:18:11,450 where you know two things went between 434 00:18:15,880 --> 00:18:13,549 themselves and it ended up with the 435 00:18:18,010 --> 00:18:15,890 positive design so we have to constantly 436 00:18:20,980 --> 00:18:18,020 keep digging into the design to 437 00:18:23,649 --> 00:18:20,990 understand how to proceed forward I 438 00:18:27,399 --> 00:18:23,659 don't know if that totally answered your 439 00:18:30,310 --> 00:18:27,409 question but I think in general because 440 00:18:31,460 --> 00:18:30,320 we have the team from curiosity it's 441 00:18:34,190 --> 00:18:31,470 helped us to 442 00:18:36,860 --> 00:18:34,200 really mesh well now as a tune for 2020 443 00:18:39,730 --> 00:18:36,870 to have those kind of experts on board 444 00:18:42,710 --> 00:18:39,740 but then I'll also have this new wave of 445 00:18:46,370 --> 00:18:42,720 new team members coming in and out of 446 00:18:49,970 --> 00:18:46,380 their perspective - its you and then 447 00:18:52,430 --> 00:18:49,980 crews m7 also asks how does a system 448 00:18:55,549 --> 00:18:52,440 engineer work with different aspects 449 00:18:58,640 --> 00:18:55,559 like EDL and if you could define EDL or 450 00:19:01,789 --> 00:18:58,650 electronics and do you have to be SME in 451 00:19:07,850 --> 00:19:01,799 several areas to be able to take on a 452 00:19:11,230 --> 00:19:07,860 systems role yeah so I'm personally I 453 00:19:13,640 --> 00:19:11,240 jumped from thermal systems engineering 454 00:19:15,409 --> 00:19:13,650 inter thermal engineering I guess we 455 00:19:17,149 --> 00:19:15,419 would call it internet systems 456 00:19:19,419 --> 00:19:17,159 engineering so I came with a strong 457 00:19:21,950 --> 00:19:19,429 background in thermal and thermal 458 00:19:24,560 --> 00:19:21,960 specifically is an area that spans all 459 00:19:28,279 --> 00:19:24,570 the different Hardware pieces so I found 460 00:19:31,310 --> 00:19:28,289 that that adjust that was fine for you 461 00:19:33,919 --> 00:19:31,320 don't have to have been an expert in 462 00:19:36,080 --> 00:19:33,929 every single field in order to become a 463 00:19:37,850 --> 00:19:36,090 good systems engineer in order to become 464 00:19:39,860 --> 00:19:37,860 a good systems engineer you have to know 465 00:19:42,500 --> 00:19:39,870 that you don't know everything and have 466 00:19:45,190 --> 00:19:42,510 a willingness to learn I guess if that 467 00:19:47,270 --> 00:19:45,200 makes sense I think having experience 468 00:19:49,730 --> 00:19:47,280 digging in deep to these different 469 00:19:52,789 --> 00:19:49,740 subsystems makes you an even better 470 00:19:55,130 --> 00:19:52,799 systems engineer and and certainly I 471 00:19:56,600 --> 00:19:55,140 think usually when they hire systems 472 00:19:59,570 --> 00:19:56,610 engineers they do look for people that 473 00:20:01,820 --> 00:19:59,580 do come from some specific background so 474 00:20:04,340 --> 00:20:01,830 hopefully that helps answer the second 475 00:20:06,799 --> 00:20:04,350 part the question there was a first part 476 00:20:09,200 --> 00:20:06,809 of the question I missed yeah how does 477 00:20:15,409 --> 00:20:09,210 the systems engineer work with different 478 00:20:17,060 --> 00:20:15,419 aspects like EDL or electronics um gosh 479 00:20:22,159 --> 00:20:17,070 how do you work with those different 480 00:20:24,620 --> 00:20:22,169 aspects well so et al is an entry 481 00:20:28,039 --> 00:20:24,630 descent and landing phase of the mission 482 00:20:30,200 --> 00:20:28,049 and so evl is a systems engineering 483 00:20:34,610 --> 00:20:30,210 problem in and of itself and that 484 00:20:37,010 --> 00:20:34,620 includes electronics and so I think in 485 00:20:39,080 --> 00:20:37,020 order to put together things like ETL 486 00:20:41,149 --> 00:20:39,090 with electronics with the telecom system 487 00:20:41,880 --> 00:20:41,159 all of those sorts of things the best 488 00:20:44,460 --> 00:20:41,890 met best 489 00:20:46,680 --> 00:20:44,470 methods have really been to just dig 490 00:20:48,720 --> 00:20:46,690 into them and learn as much as you can 491 00:20:51,180 --> 00:20:48,730 and I don't know sounds kind of like a 492 00:20:55,860 --> 00:20:51,190 vague answer but it's really the only 493 00:20:57,450 --> 00:20:55,870 way that I've found to be most 494 00:20:59,880 --> 00:20:57,460 successful in some of the trades are 495 00:21:01,620 --> 00:20:59,890 just learning as much as you can and 496 00:21:05,070 --> 00:21:01,630 knowing that you don't know everything 497 00:21:07,800 --> 00:21:05,080 and with that you learn to talk to 498 00:21:10,380 --> 00:21:07,810 people talk to all sorts of different 499 00:21:12,030 --> 00:21:10,390 kinds of people I think at JPL there's 500 00:21:14,730 --> 00:21:12,040 lots of different personalities and so 501 00:21:15,690 --> 00:21:14,740 you get a slate you know in any industry 502 00:21:17,730 --> 00:21:15,700 there's lots of different personalities 503 00:21:19,260 --> 00:21:17,740 so you get a flavor of how to tell those 504 00:21:22,260 --> 00:21:19,270 interactions with people and really 505 00:21:24,660 --> 00:21:22,270 learn from them learn to trust and not 506 00:21:27,150 --> 00:21:24,670 trust what people are telling you trust 507 00:21:30,420 --> 00:21:27,160 but verify I guess is the way to say it 508 00:21:32,400 --> 00:21:30,430 so yeah again I'm not sure every totally 509 00:21:35,240 --> 00:21:32,410 answered that but if we gave a little 510 00:21:37,950 --> 00:21:35,250 guidance based on my own experience I 511 00:21:39,660 --> 00:21:37,960 think that this is a perfect setup for 512 00:21:42,690 --> 00:21:39,670 this question that it's kind of a 513 00:21:44,340 --> 00:21:42,700 follow-up Elizabeth on YouTube asks what 514 00:21:49,020 --> 00:21:44,350 are some of the traits that are most 515 00:21:54,180 --> 00:21:49,030 important for a systems engineer oh yes 516 00:21:55,920 --> 00:21:54,190 very good meeting yeah I think so 517 00:21:58,200 --> 00:21:55,930 systems engineers right the willingness 518 00:22:00,510 --> 00:21:58,210 to learn I think is a big one the 519 00:22:01,620 --> 00:22:00,520 ability to see this gray space I think 520 00:22:05,010 --> 00:22:01,630 I've talked about that before 521 00:22:06,480 --> 00:22:05,020 but um to know that the answer might not 522 00:22:09,450 --> 00:22:06,490 be black or white and you might not have 523 00:22:11,010 --> 00:22:09,460 a hundred percent or zero percentage to 524 00:22:15,540 --> 00:22:11,020 work through those sorts of situations 525 00:22:17,130 --> 00:22:15,550 um I guess I don't know I'd like to 526 00:22:19,440 --> 00:22:17,140 think that you kind of have to be a 527 00:22:22,410 --> 00:22:19,450 little bit social because I find myself 528 00:22:24,570 --> 00:22:22,420 talking to people a lot and learning 529 00:22:27,270 --> 00:22:24,580 from them but then also trading 530 00:22:30,690 --> 00:22:27,280 information with them so like if I'm 531 00:22:31,830 --> 00:22:30,700 talking to a Power Systems Engineer and 532 00:22:34,260 --> 00:22:31,840 I'm hearing them say things about 533 00:22:36,030 --> 00:22:34,270 thermal and I might be aware of the 534 00:22:38,730 --> 00:22:36,040 thermal system problems are having I can 535 00:22:40,140 --> 00:22:38,740 help guide the power systems engineer so 536 00:22:42,120 --> 00:22:40,150 that we can all be informed of the 537 00:22:44,550 --> 00:22:42,130 problem I think a lot of it is also 538 00:22:46,380 --> 00:22:44,560 guiding the team to have a common 539 00:22:49,530 --> 00:22:46,390 knowledge of the system instead of just 540 00:22:51,510 --> 00:22:49,540 having team members in a specific rabbit 541 00:22:54,600 --> 00:22:51,520 hole and trying to understand their 542 00:22:55,650 --> 00:22:54,610 problems that way um I think of like 543 00:23:01,350 --> 00:22:55,660 specific 544 00:23:07,590 --> 00:23:01,360 things really well organized I mean do 545 00:23:10,620 --> 00:23:07,600 you have to be good at math yes I think 546 00:23:13,740 --> 00:23:10,630 you have to be willing to learn and to 547 00:23:16,500 --> 00:23:13,750 be very precise I think that's the most 548 00:23:18,600 --> 00:23:16,510 important thing do you think your 549 00:23:21,510 --> 00:23:18,610 creative side also played a role in this 550 00:23:25,500 --> 00:23:21,520 too what you used to do versus what you 551 00:23:28,440 --> 00:23:25,510 do now does it parallels than that yeah 552 00:23:30,420 --> 00:23:28,450 I think um I guess I'm given it was a 553 00:23:34,020 --> 00:23:30,430 little bit of thought in the last few 554 00:23:36,000 --> 00:23:34,030 years when we were orchestrating these 555 00:23:37,620 --> 00:23:36,010 tests and bringing these big teams of 556 00:23:40,080 --> 00:23:37,630 people together with the system level 557 00:23:42,360 --> 00:23:40,090 testing I found myself kind of acting 558 00:23:43,710 --> 00:23:42,370 like a stage manager you know bringing 559 00:23:46,530 --> 00:23:43,720 all these different people into the 560 00:23:49,020 --> 00:23:46,540 picture I think someone else had 561 00:23:51,420 --> 00:23:49,030 mentioned systems engineers are kind of 562 00:23:53,160 --> 00:23:51,430 like the producers so you have to if you 563 00:23:54,360 --> 00:23:53,170 see a problem and one thing is going in 564 00:23:56,430 --> 00:23:54,370 this direction you have to kind of 565 00:23:58,380 --> 00:23:56,440 offset that with this thing so it's a 566 00:24:00,290 --> 00:23:58,390 constant trade and keeping the system 567 00:24:02,730 --> 00:24:00,300 balanced and everything like that so 568 00:24:04,590 --> 00:24:02,740 that's been kind of fun I guess 569 00:24:06,540 --> 00:24:04,600 systems engineering is also really 570 00:24:09,000 --> 00:24:06,550 interesting because you you transition 571 00:24:11,070 --> 00:24:09,010 with the mission so you know you start 572 00:24:12,840 --> 00:24:11,080 out in the design phase so you have to 573 00:24:14,790 --> 00:24:12,850 have a specific set of skills for design 574 00:24:17,610 --> 00:24:14,800 when you get into the more of the 575 00:24:20,100 --> 00:24:17,620 testing verification validation of the 576 00:24:21,870 --> 00:24:20,110 mission I you know you have a different 577 00:24:24,180 --> 00:24:21,880 set of skills where you have to think 578 00:24:25,920 --> 00:24:24,190 about things analytically and then when 579 00:24:28,430 --> 00:24:25,930 you go to the operations phase that's 580 00:24:31,260 --> 00:24:28,440 where you're kind of in a hot seat and 581 00:24:32,790 --> 00:24:31,270 for me I've always thought that you know 582 00:24:35,040 --> 00:24:32,800 you kind of feel like a performer when 583 00:24:38,070 --> 00:24:35,050 you're an operator because on the spot 584 00:24:41,100 --> 00:24:38,080 and maybe there's not a stage there's a 585 00:24:42,840 --> 00:24:41,110 darkroom but um yeah I'm sure there's 586 00:24:45,210 --> 00:24:42,850 one creativity in there too 587 00:24:47,340 --> 00:24:45,220 I think that's a great answer and 588 00:24:50,100 --> 00:24:47,350 Marina's kind of switched gears here to 589 00:24:52,170 --> 00:24:50,110 Marley on YouTube who wants to know how 590 00:24:57,380 --> 00:24:52,180 long does it take to get from Earth to 591 00:25:00,930 --> 00:24:57,390 Mars yeah it takes about six months so 592 00:25:04,250 --> 00:25:00,940 for our Mars 2020 mission we have a 593 00:25:09,090 --> 00:25:04,260 slightly longer cruise period than they 594 00:25:12,390 --> 00:25:09,100 on MSL curiosity but yeah it takes about 595 00:25:21,210 --> 00:25:12,400 six months where you're landing now 596 00:25:23,060 --> 00:25:21,220 February 18th so we got money 21 yes 597 00:25:28,170 --> 00:25:23,070 very much 598 00:25:31,470 --> 00:25:28,180 and then we have another one from Julie 599 00:25:34,350 --> 00:25:31,480 on you to ask what's the hardest part of 600 00:25:43,640 --> 00:25:34,360 planning big system level tests and 601 00:25:48,180 --> 00:25:43,650 getting a mission ready for launch I 602 00:25:50,460 --> 00:25:48,190 think it's so it's the most difficult 603 00:25:53,340 --> 00:25:50,470 but it's also the most rewarding 604 00:25:57,210 --> 00:25:53,350 I think it's seeing the team come 605 00:25:58,020 --> 00:25:57,220 together so there are all these 606 00:25:59,480 --> 00:25:58,030 subsystems 607 00:26:01,410 --> 00:25:59,490 they've all been working independently 608 00:26:03,390 --> 00:26:01,420 maybe there's a little bit of cross 609 00:26:05,490 --> 00:26:03,400 talking between those subsystems but as 610 00:26:07,020 --> 00:26:05,500 part of a plan or planning for these 611 00:26:09,510 --> 00:26:07,030 system tests and even planning for 612 00:26:11,100 --> 00:26:09,520 launch you have to pull these people 613 00:26:15,260 --> 00:26:11,110 together and they come from such 614 00:26:17,220 --> 00:26:15,270 different expertise is and different 615 00:26:19,020 --> 00:26:17,230 processes even and different ways of 616 00:26:20,580 --> 00:26:19,030 doing things and you have to force them 617 00:26:22,080 --> 00:26:20,590 into different processes that you're 618 00:26:23,280 --> 00:26:22,090 going to use for launch or the process 619 00:26:26,190 --> 00:26:23,290 you're gonna use for the test or 620 00:26:28,590 --> 00:26:26,200 whatever it may be and it's it's 621 00:26:31,350 --> 00:26:28,600 difficult to get people on board with 622 00:26:32,790 --> 00:26:31,360 new processes and new ways of doing 623 00:26:35,280 --> 00:26:32,800 things and new ways of thinking about 624 00:26:37,380 --> 00:26:35,290 the spacecraft so all those sorts of 625 00:26:38,970 --> 00:26:37,390 things I I found it was the most 626 00:26:40,920 --> 00:26:38,980 rewarding because after these tests 627 00:26:43,620 --> 00:26:40,930 completed and as they were you know 628 00:26:46,710 --> 00:26:43,630 nearing preparation to begin and 629 00:26:48,360 --> 00:26:46,720 complete you really saw the team's start 630 00:26:51,060 --> 00:26:48,370 to mesh and to start to talk to each 631 00:26:52,800 --> 00:26:51,070 other and instead of having me or you 632 00:26:54,360 --> 00:26:52,810 know one of my colleagues as one of the 633 00:26:56,250 --> 00:26:54,370 middle people you see them actually 634 00:26:57,660 --> 00:26:56,260 talking to each other now and so it's 635 00:27:00,090 --> 00:26:57,670 just this really cool meshing of the 636 00:27:02,880 --> 00:27:00,100 team it's difficult buddy it's a lot of 637 00:27:06,690 --> 00:27:02,890 it's really a nice community when it 638 00:27:09,080 --> 00:27:06,700 does happen that's great and then I have 639 00:27:11,940 --> 00:27:09,090 one last question and it's from 640 00:27:14,580 --> 00:27:11,950 eight-year-old Sienna and she wants to 641 00:27:16,220 --> 00:27:14,590 know tell us more about the type of 642 00:27:18,409 --> 00:27:16,230 dancing you did and 643 00:27:26,710 --> 00:27:18,419 tell us how science and art both make 644 00:27:32,900 --> 00:27:26,720 you happy oh gosh um okay so I used to 645 00:27:34,340 --> 00:27:32,910 do ballet tap and jazz and when I was in 646 00:27:38,030 --> 00:27:34,350 college I took a little bit of modern 647 00:27:41,150 --> 00:27:38,040 dance and I did a lot of theater musical 648 00:27:43,340 --> 00:27:41,160 theater have you and I would always get 649 00:27:46,100 --> 00:27:43,350 cast as the kind of like quirky nerdy 650 00:27:49,850 --> 00:27:46,110 character in school so there's always 651 00:27:53,150 --> 00:27:49,860 some type casting going on there too 652 00:27:56,390 --> 00:27:53,160 so yeah that's what I used to do what 653 00:27:58,070 --> 00:27:56,400 was the second part of the question just 654 00:28:03,530 --> 00:27:58,080 really quickly how do they both make you 655 00:28:06,200 --> 00:28:03,540 happy oh gosh in such different ways it 656 00:28:07,159 --> 00:28:06,210 uses different parts of your soul I 657 00:28:10,789 --> 00:28:07,169 guess so 658 00:28:13,850 --> 00:28:10,799 dance me singing and I guess even acting 659 00:28:17,030 --> 00:28:13,860 um you know that kind of gets out like 660 00:28:20,510 --> 00:28:17,040 my my soul and like performing I was 661 00:28:24,020 --> 00:28:20,520 getting very cheesy but it's it's very 662 00:28:26,240 --> 00:28:24,030 true um and then the engineering it 663 00:28:28,970 --> 00:28:26,250 really gets like my brain so I think it 664 00:28:31,820 --> 00:28:28,980 fulfills that curiosity in your brain 665 00:28:34,549 --> 00:28:31,830 that you get a little bit of that with 666 00:28:36,620 --> 00:28:34,559 dance but it really gets fulfilled a bit 667 00:28:40,010 --> 00:28:36,630 'space and with all the different 668 00:28:43,130 --> 00:28:40,020 missions going on at JPL and so I find 669 00:28:44,840 --> 00:28:43,140 that you have to have I think in Pilates 670 00:28:46,669 --> 00:28:44,850 they say I think of mind and body you 671 00:28:49,490 --> 00:28:46,679 have to fulfill both and so I think 672 00:28:52,159 --> 00:28:49,500 through dance I found it in my body and 673 00:28:58,070 --> 00:28:52,169 through science I found it in my brain 674 00:28:59,960 --> 00:28:58,080 so it's great thank you so much for 675 00:29:01,580 --> 00:28:59,970 answering the questions today and thank 676 00:29:03,770 --> 00:29:01,590 you for everyone who submitted your 677
