a series of talks 5 00:00:09,750 --> 00:00:09,040 by scientists and engineers who are 6 00:00:13,190 --> 00:00:09,760 exploring 7 00:00:20,390 --> 00:00:13,200 our planet our solar system and all that 8 00:00:24,230 --> 00:00:22,310 we are starting to straighten up and fly 9 00:00:25,589 --> 00:00:24,240 right maneuver where the spacecraft will 10 00:00:27,349 --> 00:00:25,599 jettison the entry 11 00:00:29,349 --> 00:00:27,359 balance masses in preparation for 12 00:00:29,990 --> 00:00:29,359 parachute deploy and to roll over to 13 00:00:34,150 --> 00:00:30,000 give the radar 14 00:00:39,670 --> 00:00:37,430 complicated indicate shoe deploy 15 00:00:41,430 --> 00:00:39,680 the navigation has confirmed that the 16 00:00:43,670 --> 00:00:41,440 parachute has deployed and we are seeing 17 00:00:45,670 --> 00:00:43,680 significant deceleration 18 00:00:48,549 --> 00:00:45,680 in the velocity our current velocity is 19 00:00:50,389 --> 00:00:48,559 450 meters per second at an altitude of 20 00:00:53,189 --> 00:00:50,399 about 12 kilometers from the surface of 21 00:00:57,189 --> 00:00:55,750 heat shield set press advance has now 22 00:00:58,549 --> 00:00:57,199 slowed to subsonic 23 00:01:00,709 --> 00:00:58,559 speeds and the heat shield has been 24 00:01:02,389 --> 00:01:00,719 separated this allows 25 00:01:04,469 --> 00:01:02,399 both the radar and the cameras to get 26 00:01:07,109 --> 00:01:04,479 their first look at the surface 27 00:01:08,950 --> 00:01:07,119 current velocity is 145 meters per 28 00:01:11,030 --> 00:01:08,960 second and an altitude of about 29 00:01:27,749 --> 00:01:11,040 10 km nine and a half kilometers above 30 00:01:32,069 --> 00:01:30,069 now filter converge velocity solution 31 00:01:34,950 --> 00:01:32,079 3.3 meters per second 32 00:01:35,990 --> 00:01:34,960 altitude 7.4 kilometers now has radar 33 00:01:38,230 --> 00:01:36,000 lock on the ground 34 00:01:39,270 --> 00:01:38,240 current velocity is about 100 meters per 35 00:01:46,069 --> 00:01:39,280 second 36 00:01:49,910 --> 00:01:47,990 perseverance is continuing to descend on 37 00:01:52,789 --> 00:01:49,920 the parachute we are coming 38 00:01:54,230 --> 00:01:52,799 up on the initialization of terrain 39 00:01:56,069 --> 00:01:54,240 relative navigation 40 00:01:58,389 --> 00:01:56,079 and subsequently the priming of the 41 00:02:00,709 --> 00:01:58,399 landing engines our current velocity is 42 00:02:07,350 --> 00:02:00,719 about 90 meters per second at an 43 00:02:11,350 --> 00:02:09,749 ovf valid we have confirmation that the 44 00:02:12,710 --> 00:02:11,360 lander vision system has produced a 45 00:02:14,869 --> 00:02:12,720 valid solution 46 00:02:16,070 --> 00:02:14,879 and part of terrain relative navigation 47 00:02:19,510 --> 00:02:16,080 priming 48 00:02:25,990 --> 00:02:19,520 pba is nominal we have timing of the 49 00:02:29,670 --> 00:02:28,710 back shell set current velocity is 83 50 00:02:32,630 --> 00:02:29,680 meters per second 51 00:02:33,430 --> 00:02:32,640 at about 2.6 kilometers from the surface 52 00:02:34,869 --> 00:02:33,440 mars 53 00:02:36,470 --> 00:02:34,879 we have confirmation that the back shell 54 00:02:38,070 --> 00:02:36,480 has separated 55 00:02:40,550 --> 00:02:38,080 we are currently performing the divert 56 00:02:41,430 --> 00:02:40,560 maneuver current velocity is about 75 57 00:02:44,150 --> 00:02:41,440 meters per second 58 00:02:45,990 --> 00:02:44,160 at an altitude of about a kilometer off 59 00:02:50,229 --> 00:02:46,000 the surface of mars 60

--> 00:07:59,919 writing software for the deep space 160 00:08:03,749 --> 00:08:02,160 network he worked on flight software for 161 00:08:05,830 --> 00:08:03,759 the curiosity rover 162 00:08:08,230 --> 00:08:05,840 and is now the mars helicopter 163 00:08:12,070 --> 00:08:08,240 operations lead at jpl 164 00:08:15,270 --> 00:08:12,080 please welcome timothy cannon hi tim 165 00:08:17,029 --> 00:08:15,280 hi good evening everyone thanks so much 166 00:08:18,550 --> 00:08:17,039 for being with us tonight tim 167 00:08:20,469 --> 00:08:18,560 can you tell us a little bit about who 168 00:08:23,909 --> 00:08:20,479 you are and how you got to work on this 169 00:08:25,430 --> 00:08:23,919 project and let's bring up image three 170 00:08:27,749 --> 00:08:25,440 well first of all i want to congratulate 171 00:08:29,430 --> 00:08:27,759 perseverance and doing a great job 172 00:08:31,029 --> 00:08:29,440 and bringing the ingenuity helicopter 173 00:08:32,230 --> 00:08:31,039 into a nice soft landing on the surface 174 00:08:34,630 --> 00:08:32,240 of mars 175 00:08:36,389 --> 00:08:34,640 so i worked at jpl for a number of 176 00:08:37,670 --> 00:08:36,399 projects over the years i started in the 177 00:08:40,310 --> 00:08:37,680 deep space network 178 00:08:42,070 --> 00:08:40,320 i worked on the cassini project and most 179 00:08:44,710 --> 00:08:42,080 recently before the helicopter i worked 180 00:08:46,389 --> 00:08:44,720 on the curiosity rover flight software 181 00:08:47,990 --> 00:08:46,399 as a matter of fact much of my software 182 00:08:50,550 --> 00:08:48,000 that i wrote for curiosity is now 183 00:08:53,030 --> 00:08:50,560 running on perseverance as well 184 00:08:54,470 --> 00:08:53,040 so most recently our group had developed 185 00:08:55,990 --> 00:08:54,480 a set of software that we used on a 186 00:08:57,590 --> 00:08:56,000 number of projects internally so i was 187 00:09:00,389 --> 00:08:57,600 asked to be the software lead 188 00:09:02,070 --> 00:09:00,399 for the helicopter and we had a team of 189 00:09:04,070 --> 00:09:02,080 four or five programmers that put the 190 00:09:06,230 --> 00:09:04,080 software together and tested it 191 00:09:07,190 --> 00:09:06,240 and since we operate the helicopter via 192 00:09:09,110 --> 00:09:07,200 the software 193 00:09:11,110 --> 00:09:09,120 i was asked to be the operations lead to 194 00:09:14,949 --> 00:09:11,120 actually operate the helicopter once we 195 00:09:18,389 --> 00:09:16,630 it's an incredible story of how you 196 00:09:19,910 --> 00:09:18,399 ended up where you are today 197 00:09:22,630 --> 00:09:19,920 but let's talk a little bit about the 198 00:09:24,070 --> 00:09:22,640 helicopter how do you build a helicopter 199 00:09:26,389 --> 00:09:24,080 that's going to be able to fly 200 00:09:28,790 --> 00:09:26,399 on mars and if we could see image 4 201 00:09:30,389 --> 00:09:28,800 please 202 00:09:31,670 --> 00:09:30,399 well when you design a helicopter for 203 00:09:33,430 --> 00:09:31,680 mars you have to keep in mind the 204 00:09:35,269 --> 00:09:33,440 environments you're going to fly in 205 00:09:37,590 --> 00:09:35,279 mars has a very thin atmosphere so we 206 00:09:39,030 --> 00:09:37,600 need to design it to be very lightweight 207 00:09:40,870 --> 00:09:39,040 the blades are very lightweight they 208 00:09:43,110 --> 00:09:40,880 spin very quickly 209 00:09:45,110 --> 00:09:43,120 and also because we are so far from 210 00:09:46,949 --> 00:09:45,120 earth you can't have a joystick and just 211 00:09:48,710 --> 00:09:46,959 fly it like you would a drone at home 212 00:09:49,990 --> 00:09:48,720 we had to write the software so it could 213 00:09:52,389 --> 00:09:50,000 fly itself we 214 00:09:54,230 --> 00:09:52,399 basically get a set of instructions and 215 00:09:55,829 --> 00:09:54,240 the helicopter takes off and flies to 216 00:09:57,670 --> 00:09:55,839 the places we tell it to 217 00:09:59,190 --> 00:09:57,680 and we had an extensive test program 218 00:10:00,870 --> 00:09:59,200 here on earth where we 219 00:10:02,710 --> 00:10:00,880 did many flights in a special chamber 220 00:10:04,310 --> 00:10:02,720 jpl to prove that our software would 221 00:10:06,630 --> 00:10:04,320 work when we got to mars 222 00:10:08,069 --> 00:10:06,640 so we're very excited to be finally here 223 00:10:09,750 --> 00:10:08,079 and actually able to 224 00:10:13,750 --> 00:10:09,760 execute these flights on the surface of 225 00:10:17,269 --> 00:10:15,910 it's incredible and i can't wait for the 226 00:10:18,870 --> 00:10:17,279 chance to see all of that 227 00:10:20,550 --> 00:10:18,880 um we're actually gonna bring the 228 00:10:23,350 --> 00:10:20,560 audience in right now and let them 229 00:10:24,790 --> 00:10:23,360 ask the next question for tim so sarah 230 00:10:29,030 --> 00:10:24,800 i'm sure they're excited out there 231 00:10:35,269 --> 00:10:32,470 so elitia on linkedin is asking 232 00:10:35,990 --> 00:10:35,279 what are or what is one of the greatest 233 00:10:40,310 --> 00:10:36,000 challenges 234 00:10:44,550 --> 00:10:42,550 well as i mentioned before the 235 00:10:46,230 --> 00:10:44,560 atmosphere is super thin 236 00:10:47,590 --> 00:10:46,240 and so you can't design a helicopter 237 00:10:50,230 --> 00:10:47,600 like you do on earth 238 00:10:51,110 --> 00:10:50,240 and so we had to do very new kinds of 239 00:10:52,949 --> 00:10:51,120 algorithms 240 00:10:55,430 --> 00:10:52,959 in the software we had to design 241 00:10:57,110 --> 00:10:55,440 hardware especially for flying on mars 242 00:10:59,030 --> 00:10:57,120 and so all of that was challenged we did 243 00:11:00,470 --> 00:10:59,040 things that have never been done before 244 00:11:02,069 --> 00:11:00,480 it's shorter right brother moment in 245 00:11:03,030 --> 00:11:02,079 that we get to go to a planet somewhere 246 00:11:04,710 --> 00:11:03,040 outside of earth 247 00:11:06,710 --> 00:11:04,720 and try a helicopter there that's never 248 00:11:07,829 --> 00:11:06,720 been tried before so we had to do 249 00:11:14,949 --> 00:11:07,839 special 250 00:11:16,550 --> 00:11:14,959 it happen 251 00:11:18,230 --> 00:11:16,560 sarah let's do one more question from 252 00:11:20,470 --> 00:11:18,240 the audience for tim 253 00:11:21,910 --> 00:11:20,480 sure thing i like this one uh this is 254 00:11:23,750 --> 00:11:21,920 from margie on facebook 255 00:11:25,509 --> 00:11:23,760 and she's asking for her nine-year-old 256 00:11:28,710 --> 00:11:25,519 son jonah so we've got 257 00:11:30,790 --> 00:11:28,720 a young space fan out here so he says 258 00:11:33,030 --> 00:11:30,800 how will ingenuity fly in the different 259 00:11:35,910 --> 00:11:33,040 gravity 260 00:11:36,630 --> 00:11:35,920 well that's a great question and we 261 00:11:39,350 --> 00:11:36,640 designed it 262 00:11:41,190 --> 00:11:39,360 to be lightweight because mars has about 263 00:11:43,269 --> 00:11:41,200 one-third the gravity of earth 264 00:11:45,030 --> 00:11:43,279 and so we had to design that in when we 265 00:11:45,829 --> 00:11:45,040 did it it's actually too heavy to fly on 266 00:11:48,069 --> 00:11:45,839 earth 267 00:11:49,910 --> 00:11:48,079 and so we had a special mechanism when 268 00:11:52,230 --> 00:11:49,920 we tested it here on earth that would 269 00:11:54,310 --> 00:11:52,240 pull up on the top of the helicopter and 270 00:11:55,910 --> 00:11:54,320 simulate mars gravity so we could fly in 271 00:11:56,629 --> 00:11:55,920 a chamber that was pumped down to mars 272 00:11:58,150 --> 00:11:56,639 pressure 273 00:12:00,069 --> 00:11:58,160 and have a special mechanism that 274 00:12:02,230 --> 00:12:00,079 allowed us to simulate the gravity of 275 00:12:03,990 --> 00:12:02,240 mars and let it fly around the chamber 276 00:12:08,710 --> 00:12:04,000 so yes we had to keep in mind the 277 00:12:11,670 --> 00:12:10,069 it sounds like a lot of testing went 278 00:12:13,430 --> 00:12:11,680 into this project and thank you sarah 279 00:12:15,590 --> 00:12:13,440 for that great set of questions 280 00:12:16,710 --> 00:12:15,600 now as tim you alluded to earlier the 281 00:12:19,430 --> 00:12:16,720 helicopter of course 282 00:12:19,829 --> 00:12:19,440 had to get to mars somehow so joining us 283 00:12:22,629 --> 00:12:19,839 now 284 00:12:23,269 --> 00:12:22,639 is perseverance mars 2020 systems 285 00:12:26,550 --> 00:12:23,279 engineer 286 00:12:30,150 --> 00:12:26,560 dr farah alibay hi farah 287 00:12:31,110 --> 00:12:30,160 hi so this next question is actually for 288 00:12:33,190 --> 00:12:31,120 both of you 289 00:12:34,470 --> 00:12:33,200 what are the challenges of working on a 290 00:12:37,110 --> 00:12:34,480 mission like this 291 00:12:38,150 --> 00:12:37,120 separate but united let's pull up image 292 00:12:41,430 --> 00:12:38,160 number five and tim 293 00:12:44,470 --> 00:12:43,590 well as a research project that's how we 294 00:12:45,990 --> 00:12:44,480 started 295 00:12:47,990 --> 00:12:46,000 and so when we were doing all of our 296 00:12:48,870 --> 00:12:48,000 development and testing it was a very 297 00:12:51,670 --> 00:12:48,880 much a very 298 00:12:53,269 --> 00:12:51,680 fast rapid uh high high-paced 299 00:12:55,430 --> 00:12:53,279 environment where we would make changes 300 00:12:56,949 --> 00:12:55,440 we'd fix something we'd try it again 301 00:12:59,350 --> 00:12:56,959 and when you go to a project like the 302 00:13:01,030 --> 00:12:59,360 rover the perseverance rover everything 303 00:13:04,150 --> 00:13:01,040 is very structured 304 00:13:06,710 --> 00:13:04,160 and very regimented 305 00:13:07,190 --> 00:13:06,720 with lots of processes you have to do 306 00:13:09,030 --> 00:13:07,200 and 307 00:13:10,790 --> 00:13:09,040 farah has been a great harbor pilot i 308 00:13:12,310 --> 00:13:10,800 call her our harbor pilot she guided us 309 00:13:14,949 --> 00:13:12,320 through all the icebergs of 310 00:13:16,069 --> 00:13:14,959 big project land to to get us on the 311 00:13:17,829 --> 00:13:16,079 rover and to 312 00:13:19,590 --> 00:13:17,839 help us figure out how to run all these 313 00:13:19,990 --> 00:13:19,600 things together and it has been a 314 00:13:22,230 --> 00:13:20,000 challenge 315 00:13:24,230 --> 00:13:22,240 because we've all been remote with covid 316 00:13:25,670 --> 00:13:24,240 and working together with farah and 317 00:13:31,509 --> 00:13:25,680 the rest of the team has been a real 318 00:13:35,750 --> 00:13:32,870 i'm sure it's been a great learning 319 00:13:37,350 --> 00:13:35,760 experience too far how about for you 320 00:13:39,030 --> 00:13:37,360 yeah i mean as tim mentioned one of the 321 00:13:39,829 --> 00:13:39,040 craziest thing is tim and i have 322 00:13:42,949 --> 00:13:39,839 actually never 323 00:13:44,470 --> 00:13:42,959 met in person so i i joined the team you 324 00:13:45,590 --> 00:13:44,480 know i've been on the perseverance team 325 00:13:47,269 --> 00:13:45,600 for a long time 326 00:13:49,110 --> 00:13:47,279 but i actually only started working on 327 00:13:50,870 --> 00:13:49,120 the helicopter right around launch when 328 00:13:52,629 --> 00:13:50,880 we really started thinking 329 00:13:54,550 --> 00:13:52,639 well this thing's on its way to mars we 330 00:13:56,470 --> 00:13:54,560 better figure out how to operate it 331 00:13:58,550 --> 00:13:56,480 and so i was brought along and and you 332 00:14:00,230 --> 00:13:58,560 know we were deep in covet and i've been 333 00:14:01,670 --> 00:14:00,240 interacting with the team remotely and 334 00:14:03,590 --> 00:14:01,680 it's it's crazy because i feel like 335 00:14:05,269 --> 00:14:03,600 we've become close friends even though 336 00:14:07,030 --> 00:14:05,279 you know we've never actually physically 337 00:14:09,509 --> 00:14:07,040 met um but 338 00:14:10,069 --> 00:14:09,519 one of the challenges with helicopter is 339 00:14:11,670 --> 00:14:10,079 unlike 340 00:14:13,350 --> 00:14:11,680 other instruments for example on the 341 00:14:15,590 --> 00:14:13,360 rover typically we're used to bringing 342 00:14:17,829 --> 00:14:15,600 the instruments with us wherever we go 343 00:14:19,990 --> 00:14:17,839 whereas with ingenuity you know for the 344 00:14:21,829 --> 00:14:20,000 past few souls now on mars 345 00:14:24,069 --> 00:14:21,839 we've been looking for a place to drop 346 00:14:26,069 --> 00:14:24,079 it off right we we are looking for a 347 00:14:27,350 --> 00:14:26,079 flat environment where we can leave the 348 00:14:29,269 --> 00:14:27,360 helicopter and then 349 00:14:30,550 --> 00:14:29,279 an area for us to watch it from and take 350 00:14:32,150 --> 00:14:30,560 those videos 351 00:14:34,550 --> 00:14:32,160 because you know if you don't have a 352 00:14:35,990 --> 00:14:34,560 picture it didn't happen um and so 353 00:14:37,990 --> 00:14:36,000 so it's a little bit unique in that 354 00:14:39,590 --> 00:14:38,000 sense that you know we it's a different 355 00:14:40,629 --> 00:14:39,600 mission we're bringing it along with us 356 00:14:43,910 --> 00:14:40,639 it has its own 357 00:14:45,350 --> 00:14:43,920 needs um and we have to help it figure 358 00:14:46,230 --> 00:14:45,360 out you know we have to help it achieve 359 00:14:47,829 --> 00:14:46,240 its goals and 360 00:14:49,910 --> 00:14:47,839 and that's really what perseverance is 361 00:14:50,710 --> 00:14:49,920 there for in for this particular tech 362 00:14:52,629 --> 00:14:50,720 demo is 363 00:14:53,990 --> 00:14:52,639 we are there to set the stage for the 364 00:14:56,949 --> 00:14:54,000 first flight on mars 365 00:15:00,150 --> 00:14:56,959 um and help our our friend uh achieve 366 00:15:04,550 --> 00:15:02,150 i mean what a great example of teamwork 367 00:15:06,150 --> 00:15:04,560 especially during the times of kovid 368 00:15:07,829 --> 00:15:06,160 tim we're going to come back to you in a 369 00:15:09,110 --> 00:15:07,839 little bit for some more questions but 370 00:15:10,150 --> 00:15:09,120 right now we're going to keep chatting 371 00:15:12,389 --> 00:15:10,160 with farah 372 00:15:13,990 --> 00:15:12,399 who has been a systems engineer at jpl 373 00:15:15,910 --> 00:15:14,000 for the past seven years 374 00:15:18,230 --> 00:15:15,920 working on several missions including 375 00:15:19,350 --> 00:15:18,240 the insight mars lander and marco 376 00:15:20,870 --> 00:15:19,360 cubesats 377 00:15:22,790 --> 00:15:20,880 today one of her roles on the 378 00:15:24,310 --> 00:15:22,800 perseverance mission is to lead the 379 00:15:26,310 --> 00:15:24,320 operations interface 380 00:15:27,990 --> 00:15:26,320 with the mars helicopter technology 381 00:15:29,749 --> 00:15:28,000 demonstration 382 00:15:31,910 --> 00:15:29,759 so far you've had a pretty exciting 383 00:15:33,910 --> 00:15:31,920 month you're living on mars time right 384 00:15:36,629 --> 00:15:33,920 now can you explain what is mars time 385 00:15:39,590 --> 00:15:36,639 and why are you on it 386 00:15:41,350 --> 00:15:39,600 yeah so it's currently about 8 45 a.m 387 00:15:44,790 --> 00:15:41,360 for perseverance right now 388 00:15:46,790 --> 00:15:44,800 um which well so it's not 8 45 a.m for 389 00:15:48,470 --> 00:15:46,800 me but what i do right now and what the 390 00:15:49,269 --> 00:15:48,480 rest of the perseverance team is doing 391 00:15:51,509 --> 00:15:49,279 is that 392 00:15:53,430 --> 00:15:51,519 we are working during the martian night 393 00:15:56,389 --> 00:15:53,440 and that's what we call mars time 394 00:15:57,990 --> 00:15:56,399 so our rover is too far away from earth 395 00:15:59,829 --> 00:15:58,000 and so we can't just command it you know 396 00:16:01,749 --> 00:15:59,839 it's not like we sit behind our desks 397 00:16:02,790 --> 00:16:01,759 with joysticks driving them over i wish 398 00:16:05,030 --> 00:16:02,800 it was that way 399 00:16:06,870 --> 00:16:05,040 mars is way too far so when we send 400 00:16:09,030 --> 00:16:06,880 signals to mars you know they're radio 401 00:16:10,949 --> 00:16:09,040 signals they go at the speed of light 402 00:16:13,030 --> 00:16:10,959 but it's so far away that it takes about 403 00:16:13,749 --> 00:16:13,040 13 minutes right now for a signal to get 404 00:16:16,150 --> 00:16:13,759 from earth 405 00:16:17,269 --> 00:16:16,160 to mars and then another 13 minutes for 406 00:16:19,110 --> 00:16:17,279 it to get back 407 00:16:20,870 --> 00:16:19,120 so it'd be really long and boring day if 408 00:16:22,629 --> 00:16:20,880 we were sending a command and waiting 409 00:16:26,150 --> 00:16:22,639 each time for an answer 410 00:16:28,710 --> 00:16:26,160 so what we do instead is that each night 411 00:16:29,509 --> 00:16:28,720 the rover sends us information it sends 412 00:16:31,670 --> 00:16:29,519 us images 413 00:16:32,550 --> 00:16:31,680 it sends us data it tells us what it did 414 00:16:34,870 --> 00:16:32,560 that day 415 00:16:36,790 --> 00:16:34,880 we as a team analyze it so we go into 416 00:16:39,590 --> 00:16:36,800 work at about 6 p.m 417 00:16:40,870 --> 00:16:39,600 perseverance time every night and then 418 00:16:42,710 --> 00:16:40,880 we analyze the data 419 00:16:44,470 --> 00:16:42,720 we prepare a plan for the next day as a 420 00:16:45,509 --> 00:16:44,480 team and then we send it back up to the 421 00:16:47,509 --> 00:16:45,519 rover 422 00:16:49,509 --> 00:16:47,519 and we send it up before it wakes up in 423 00:16:51,829 --> 00:16:49,519 the morning at about 8 a.m 424 00:16:53,990 --> 00:16:51,839 so we work the martian night shift right 425 00:16:55,269 --> 00:16:54,000 which okay that seems fine you just 426 00:16:57,829 --> 00:16:55,279 shift your schedule 427 00:16:59,910 --> 00:16:57,839 well it's not that easy because a 428 00:17:03,269 --> 00:16:59,920 martian day which is we call it a 429 00:17:03,990 --> 00:17:03,279 saw is actually about 24 hours and 40 430 00:17:06,549 --> 00:17:04,000 minutes 431 00:17:07,429 --> 00:17:06,559 so it's just a little longer than earth 432 00:17:10,230 --> 00:17:07,439 so even though 433 00:17:12,309 --> 00:17:10,240 i start my day at the same time on mars 434 00:17:14,870 --> 00:17:12,319 every day at about 6 pm every day 435 00:17:16,630 --> 00:17:14,880 my start time on earth shifts by 40 436 00:17:17,590 --> 00:17:16,640 minutes every day so this morning for 437 00:17:20,150 --> 00:17:17,600 example 438 00:17:20,630 --> 00:17:20,160 my wake up time was about you know 4 30 439 00:17:23,270 --> 00:17:20,640 a.m 440 00:17:24,230 --> 00:17:23,280 tomorrow it'll be more like five to 5 10 441 00:17:25,990 --> 00:17:24,240 and so on 442 00:17:27,350 --> 00:17:26,000 so we're coming up this week and next 443 00:17:27,990 --> 00:17:27,360 week that's why i was able to join you 444 00:17:29,990 --> 00:17:28,000 today 445 00:17:31,590 --> 00:17:30,000 in in days where the martian night is 446 00:17:33,669 --> 00:17:31,600 lining up with the earth day 447 00:17:34,950 --> 00:17:33,679 but i just came out of doing the night 448 00:17:36,310 --> 00:17:34,960 shift of of 449 00:17:38,710 --> 00:17:36,320 having to wake up in the middle of the 450 00:17:40,549 --> 00:17:38,720 night so it's just a shifting schedule 451 00:17:41,830 --> 00:17:40,559 and we're doing that for the first 90 452 00:17:43,590 --> 00:17:41,840 days of the mission 453 00:17:45,270 --> 00:17:43,600 because those are critical times we need 454 00:17:47,029 --> 00:17:45,280 to be working every single day on the 455 00:17:47,430 --> 00:17:47,039 rover to get everything checked out to 456 00:17:49,669 --> 00:17:47,440 get 457 00:17:51,190 --> 00:17:49,679 the ingenuity mission done all of those 458 00:17:53,990 --> 00:17:51,200 key activities that everyone's so 459 00:17:57,430 --> 00:17:55,270 i mean that's definitely a lot of 460 00:17:58,870 --> 00:17:57,440 dedication that y'all's team are putting 461 00:18:01,430 --> 00:17:58,880 into this 462 00:18:03,270 --> 00:18:01,440 as we saw before the rover has safely 463 00:18:05,110 --> 00:18:03,280 made it to mars and that video is just 464 00:18:06,230 --> 00:18:05,120 incredible watching it land i never get 465 00:18:08,630 --> 00:18:06,240 tired of it 466 00:18:10,390 --> 00:18:08,640 can you explain your role in relation to 467 00:18:12,870 --> 00:18:10,400 the helicopter mission and let's pull up 468 00:18:15,270 --> 00:18:12,880 image six 469 00:18:16,549 --> 00:18:15,280 yeah so as tim mentioned my job 470 00:18:19,430 --> 00:18:16,559 basically is to 471 00:18:19,750 --> 00:18:19,440 it is to help accommodate the helicopter 472 00:18:21,430 --> 00:18:19,760 uh 473 00:18:23,190 --> 00:18:21,440 tech demo so and there's really two 474 00:18:24,310 --> 00:18:23,200 parts to this right now you can see in 475 00:18:26,230 --> 00:18:24,320 the picture actually 476 00:18:27,830 --> 00:18:26,240 the helicopter is tucked in under the 477 00:18:29,029 --> 00:18:27,840 belly of the rover it's actually 478 00:18:31,190 --> 00:18:29,039 horizontal 479 00:18:33,270 --> 00:18:31,200 below the rover it's connected right it 480 00:18:34,470 --> 00:18:33,280 gets it gets heat it gets we can 481 00:18:36,310 --> 00:18:34,480 communicate with it 482 00:18:38,630 --> 00:18:36,320 and we have to deploy it on the surface 483 00:18:41,190 --> 00:18:38,640 of mars so in the upcoming weeks here 484 00:18:42,789 --> 00:18:41,200 once we find a site that's suitable we 485 00:18:44,630 --> 00:18:42,799 are going to go through a deployment 486 00:18:46,870 --> 00:18:44,640 process where we go from 487 00:18:48,710 --> 00:18:46,880 the helicopter being horizontal to going 488 00:18:51,430 --> 00:18:48,720 all the way vertical 489 00:18:52,950 --> 00:18:51,440 and then there's the last the last day 490 00:18:54,950 --> 00:18:52,960 of our deployment 491 00:18:57,270 --> 00:18:54,960 is when we separate the helicopter from 492 00:18:57,669 --> 00:18:57,280 the rover and what's special about that 493 00:18:59,750 --> 00:18:57,679 day 494 00:19:01,669 --> 00:18:59,760 is that from the moment that we separate 495 00:19:03,909 --> 00:19:01,679 from the helicopter from the rover 496 00:19:06,150 --> 00:19:03,919 we have to drive off of it and expose 497 00:19:09,270 --> 00:19:06,160 the solar panels from the helicopter 498 00:19:11,430 --> 00:19:09,280 within 24 hours of that drop because 499 00:19:12,470 --> 00:19:11,440 if we don't drive off on time if we have 500 00:19:13,510 --> 00:19:12,480 any problem 501 00:19:15,830 --> 00:19:13,520 then there's a chance that the 502 00:19:17,110 --> 00:19:15,840 helicopter might not survive the martian 503 00:19:18,789 --> 00:19:17,120 night which is so cold 504 00:19:21,270 --> 00:19:18,799 because it needs that energy from the 505 00:19:21,990 --> 00:19:21,280 solar panels so my job has to be been to 506 00:19:25,909 --> 00:19:22,000 coordinate 507 00:19:28,230 --> 00:19:25,919 rover side activities 508 00:19:29,990 --> 00:19:28,240 to get that deployment done to drive off 509 00:19:31,110 --> 00:19:30,000 to do all of the imaging during the 510 00:19:33,430 --> 00:19:31,120 flights 511 00:19:35,350 --> 00:19:33,440 and to coordinate for example 512 00:19:37,510 --> 00:19:35,360 communicating with the helicopter 513 00:19:39,909 --> 00:19:37,520 the helicopter can't talk directly back 514 00:19:42,870 --> 00:19:39,919 to earth it has to send its signals 515 00:19:43,430 --> 00:19:42,880 through the rover and then to earth so 516 00:19:45,029 --> 00:19:43,440 there's a 517 00:19:46,870 --> 00:19:45,039 basically i call it sort of a dance 518 00:19:48,789 --> 00:19:46,880 there's a very careful dance that has to 519 00:19:51,110 --> 00:19:48,799 happen between the two projects 520 00:19:52,549 --> 00:19:51,120 and i'm i'm sort of the choreographer 521 00:19:54,150 --> 00:19:52,559 for those dances 522 00:19:55,669 --> 00:19:54,160 to make sure that everything happens 523 00:19:56,710 --> 00:19:55,679 everyone is right there when they need 524 00:20:01,110 --> 00:19:56,720 to be 525 00:20:04,390 --> 00:20:03,510 that seems really complicated and both 526 00:20:06,310 --> 00:20:04,400 you him tim 527 00:20:08,149 --> 00:20:06,320 have talked about how this isn't like 528 00:20:09,270 --> 00:20:08,159 using a joystick to command these 529 00:20:11,270 --> 00:20:09,280 spacecraft 530 00:20:13,430 --> 00:20:11,280 so how do you prepare for something like 531 00:20:15,990 --> 00:20:13,440 that and let's pull up video seven while 532 00:20:18,870 --> 00:20:16,000 you talk us through this 533 00:20:20,630 --> 00:20:18,880 so we test test test and test some more 534 00:20:22,950 --> 00:20:20,640 i can't tell you how much time i've 535 00:20:24,070 --> 00:20:22,960 spent in the mars yard at jpl in the 536 00:20:25,750 --> 00:20:24,080 past few months so 537 00:20:27,669 --> 00:20:25,760 so the mars yard is basically a big 538 00:20:28,950 --> 00:20:27,679 sandbox it looks like mars you're seeing 539 00:20:31,350 --> 00:20:28,960 it in the video there 540 00:20:34,549 --> 00:20:31,360 and we have a replica of both ingenuity 541 00:20:36,070 --> 00:20:34,559 and perseverance perseverance the 542 00:20:37,909 --> 00:20:36,080 replica for perseverance is called 543 00:20:40,630 --> 00:20:37,919 optimism and 544 00:20:41,350 --> 00:20:40,640 we use those earth you know those earth 545 00:20:44,710 --> 00:20:41,360 robots 546 00:20:47,990 --> 00:20:44,720 to test before we get to mars and 547 00:20:50,549 --> 00:20:48,000 we test everything all of the activities 548 00:20:52,789 --> 00:20:50,559 all of the sequences the timing to make 549 00:20:54,470 --> 00:20:52,799 sure that once we do it on mars 550 00:20:55,830 --> 00:20:54,480 it's not the first time it you know it 551 00:20:57,350 --> 00:20:55,840 should be boring by the time we do it on 552 00:20:59,110 --> 00:20:57,360 mars because we've done it so many times 553 00:21:00,070 --> 00:20:59,120 so the video that you're seeing here for 554 00:21:01,909 --> 00:21:00,080 example 555 00:21:03,669 --> 00:21:01,919 is what we hope the deployment day will 556 00:21:04,630 --> 00:21:03,679 look like on mars so we tested our 557 00:21:07,590 --> 00:21:04,640 deployment 558 00:21:09,029 --> 00:21:07,600 uh and we tested driving off of it and 559 00:21:10,549 --> 00:21:09,039 the other thing that we do is that we 560 00:21:13,669 --> 00:21:10,559 also test our people 561 00:21:15,270 --> 00:21:13,679 um so back in in late january we had a 562 00:21:16,789 --> 00:21:15,280 dress rehearsal 563 00:21:19,669 --> 00:21:16,799 for the day that we're going to drop the 564 00:21:21,590 --> 00:21:19,679 helicopter so we had all of our team 565 00:21:22,789 --> 00:21:21,600 you know in the control room and i was 566 00:21:25,190 --> 00:21:22,799 sending them data 567 00:21:26,789 --> 00:21:25,200 and and you know spoofing anomalies and 568 00:21:27,430 --> 00:21:26,799 things like that and people had to react 569 00:21:29,669 --> 00:21:27,440 to them and 570 00:21:30,789 --> 00:21:29,679 and do that go no goes and decide okay 571 00:21:32,950 --> 00:21:30,799 are we gonna drive off 572 00:21:34,710 --> 00:21:32,960 is the helicopter separated what's the 573 00:21:36,549 --> 00:21:34,720 health of the helicopter so 574 00:21:38,789 --> 00:21:36,559 um so that's really helped us build 575 00:21:41,190 --> 00:21:38,799 confidence in our ability to do this 576 00:21:42,789 --> 00:21:41,200 and you know i think we're as ready as 577 00:21:43,750 --> 00:21:42,799 we can be and we're really excited to 578 00:21:45,350 --> 00:21:43,760 get to do it 579 00:21:47,029 --> 00:21:45,360 for real on mars it's a little bit like 580 00:21:48,470 --> 00:21:47,039 you know when you've rehearsed for a 581 00:21:49,750 --> 00:21:48,480 show for a long time and then you're 582 00:21:53,750 --> 00:21:49,760 ready for prime time 583 00:21:58,230 --> 00:21:56,470 i love what you said about this being a 584 00:22:00,149 --> 00:21:58,240 boring moment because you've tested it 585 00:22:01,350 --> 00:22:00,159 so many times that you want to make sure 586 00:22:02,470 --> 00:22:01,360 that it's going to work and if it goes 587 00:22:03,990 --> 00:22:02,480 according to plan 588 00:22:05,510 --> 00:22:04,000 i guarantee it will not be a boring 589 00:22:08,149 --> 00:22:05,520 moment for any of us 590 00:22:09,510 --> 00:22:08,159 that's a great way to think about it 591 00:22:11,510 --> 00:22:09,520 we're actually going to get the audience 592 00:22:12,070 --> 00:22:11,520 involved again to ask our next question 593 00:22:13,750 --> 00:22:12,080 so 594 00:22:16,470 --> 00:22:13,760 sarah what are they asking out there for 595 00:22:20,390 --> 00:22:18,549 well i'm struggling because there are so 596 00:22:23,669 --> 00:22:20,400 many great questions coming in so 597 00:22:25,190 --> 00:22:23,679 i'm having a hard time deciding um but 598 00:22:27,350 --> 00:22:25,200 there were there are a couple themes 599 00:22:27,909 --> 00:22:27,360 emerging here and so i thought these 600 00:22:31,430 --> 00:22:27,919 were really 601 00:22:33,590 --> 00:22:31,440 interesting so um for pharah so 602 00:22:35,190 --> 00:22:33,600 kurt on linkedin is asking and it's also 603 00:22:36,470 --> 00:22:35,200 kind of related to what alicia on 604 00:22:39,669 --> 00:22:36,480 youtube is asking 605 00:22:42,149 --> 00:22:39,679 having to do with the um dust storms 606 00:22:44,149 --> 00:22:42,159 so how will ingenuity react to adverse 607 00:22:45,190 --> 00:22:44,159 environmental conditions such as dust 608 00:22:47,350 --> 00:22:45,200 storms 609 00:22:49,350 --> 00:22:47,360 um you know will they work and will the 610 00:22:52,310 --> 00:22:49,360 helicopter work in stormy weather 611 00:22:53,430 --> 00:22:52,320 what do you think so we're not even 612 00:22:55,510 --> 00:22:53,440 going to try and fly 613 00:22:57,029 --> 00:22:55,520 in stormy weathers one of the advantage 614 00:22:58,470 --> 00:22:57,039 of having perseverance 615 00:23:01,110 --> 00:22:58,480 is that we actually have a weather 616 00:23:03,029 --> 00:23:01,120 station on board the rover 617 00:23:05,669 --> 00:23:03,039 so we have wind sensors we have 618 00:23:07,830 --> 00:23:05,679 temperature and we've actually been 619 00:23:09,110 --> 00:23:07,840 very closely watching the temperature 620 00:23:10,470 --> 00:23:09,120 and and the winds 621 00:23:12,390 --> 00:23:10,480 since we landed we actually had a 622 00:23:14,549 --> 00:23:12,400 meeting today where we looked at the 623 00:23:16,149 --> 00:23:14,559 you know at the at the results that we 624 00:23:18,789 --> 00:23:16,159 have so far to try and see 625 00:23:19,750 --> 00:23:18,799 okay you know not just is there anything 626 00:23:21,990 --> 00:23:19,760 going on 627 00:23:23,909 --> 00:23:22,000 on mars right now but even what time of 628 00:23:25,909 --> 00:23:23,919 day do we think it's better to fly 629 00:23:27,270 --> 00:23:25,919 um the winds on mars as it turns out are 630 00:23:29,750 --> 00:23:27,280 really predictable 631 00:23:31,430 --> 00:23:29,760 um so on from a day-to-day basis there's 632 00:23:32,230 --> 00:23:31,440 times of data that are more windy than 633 00:23:34,390 --> 00:23:32,240 others 634 00:23:35,350 --> 00:23:34,400 um so we're trying to evaluate right now 635 00:23:37,110 --> 00:23:35,360 okay 636 00:23:38,870 --> 00:23:37,120 what the what are the patterns starting 637 00:23:39,909 --> 00:23:38,880 to look like and when do we think that 638 00:23:42,630 --> 00:23:39,919 we want to fly 639 00:23:42,950 --> 00:23:42,640 to avoid sort of the gustier times of 640 00:23:45,830 --> 00:23:42,960 day 641 00:23:46,149 --> 00:23:45,840 so um so yeah we we came prepared we're 642 00:23:48,630 --> 00:23:46,159 all 643 00:23:50,230 --> 00:23:48,640 with our own weather station in order to 644 00:23:55,110 --> 00:23:50,240 to figure that out and uh 645 00:23:58,789 --> 00:23:57,350 it's always good to be very prepared um 646 00:24:00,549 --> 00:23:58,799 i think we've got time for another 647 00:24:01,909 --> 00:24:00,559 question before we move on so sarah is 648 00:24:04,310 --> 00:24:01,919 there another one out there for pharah 649 00:24:07,510 --> 00:24:04,320 that we could ask sure 650 00:24:09,750 --> 00:24:07,520 sure so alithea on linkedin is wondering 651 00:24:12,390 --> 00:24:09,760 how do you balance a lightweight 652 00:24:15,190 --> 00:24:12,400 helicopter with a helicopter that can 653 00:24:16,870 --> 00:24:15,200 endure an impact i guess maybe when it 654 00:24:18,789 --> 00:24:16,880 comes back after a flight 655 00:24:20,070 --> 00:24:18,799 so how do you balance those two things 656 00:24:21,590 --> 00:24:20,080 got to be light but it's got to be 657 00:24:22,950 --> 00:24:21,600 strong 658 00:24:25,430 --> 00:24:22,960 yeah i mean that's all part of the 659 00:24:27,510 --> 00:24:25,440 challenges of designing things for mars 660 00:24:30,230 --> 00:24:27,520 is they have to be robust for the 661 00:24:32,230 --> 00:24:30,240 environment and they also have to be 662 00:24:33,430 --> 00:24:32,240 and they also have to meet constraints 663 00:24:35,909 --> 00:24:33,440 like light like 664 00:24:37,110 --> 00:24:35,919 light in this case so um so i'm sure 665 00:24:39,350 --> 00:24:37,120 that tim could actually 666 00:24:42,070 --> 00:24:39,360 provide a lot more detail into exactly 667 00:24:44,230 --> 00:24:42,080 how um how the helicopter was designed 668 00:24:45,350 --> 00:24:44,240 uh but i can tell you that with anything 669 00:24:47,590 --> 00:24:45,360 in engineering 670 00:24:50,070 --> 00:24:47,600 there's a lot of cycles of iteration 671 00:24:51,909 --> 00:24:50,080 right we probably we start with a design 672 00:24:53,510 --> 00:24:51,919 and then we test it out we try it again 673 00:24:55,510 --> 00:24:53,520 until it meets those requirements that's 674 00:24:57,830 --> 00:24:55,520 true for the helicopter that's true for 675 00:24:59,990 --> 00:24:57,840 the rover wheels for example right we we 676 00:25:03,110 --> 00:25:00,000 redesigned the wheels on this mission 677 00:25:04,710 --> 00:25:03,120 and we tested you know dozens of 678 00:25:06,470 --> 00:25:04,720 different types of wheels 679 00:25:08,149 --> 00:25:06,480 in order to get there and i'm sure it 680 00:25:08,470 --> 00:25:08,159 was the same story for the helicopter 681 00:25:10,310 --> 00:25:08,480 but 682 00:25:14,710 --> 00:25:10,320 maybe tim can can add a little bit of 683 00:25:17,510 --> 00:25:14,720 information here 684 00:25:19,350 --> 00:25:17,520 well sure thanks farah for the intro so 685 00:25:19,830 --> 00:25:19,360 the helicopter was designed to be both 686 00:25:22,310 --> 00:25:19,840 strong 687 00:25:23,990 --> 00:25:22,320 and light so it's made of carbon fiber 688 00:25:25,110 --> 00:25:24,000 in many cases which is really light but 689 00:25:27,830 --> 00:25:25,120 really strong 690 00:25:29,350 --> 00:25:27,840 the blades are can spin really fast and 691 00:25:31,110 --> 00:25:29,360 lift the weight of the helicopter but if 692 00:25:33,269 --> 00:25:31,120 you picked one up it would be about the 693 00:25:35,909 --> 00:25:33,279 weight of a sheet of paper so the whole 694 00:25:38,149 --> 00:25:35,919 helicopter weighs about four pounds 695 00:25:38,950 --> 00:25:38,159 but yet it's able to you know lift 696 00:25:41,110 --> 00:25:38,960 itself up 697 00:25:42,630 --> 00:25:41,120 and fly around and we did many tests of 698 00:25:43,830 --> 00:25:42,640 the legs you know the legs are springy 699 00:25:44,950 --> 00:25:43,840 so that if we 700 00:25:46,549 --> 00:25:44,960 bounce a little bit on landing they 701 00:25:47,990 --> 00:25:46,559 don't break and they're very stable they 702 00:25:49,590 --> 00:25:48,000 have a wide stance 703 00:25:51,750 --> 00:25:49,600 so that if we bounce a little one side 704 00:25:52,549 --> 00:25:51,760 we can recover and it's a very tough 705 00:25:54,870 --> 00:25:52,559 system 706 00:25:56,630 --> 00:25:54,880 so we spent a lot of time we had some 707 00:25:57,269 --> 00:25:56,640 advanced partners that helped us out 708 00:25:58,710 --> 00:25:57,279 that 709 00:26:00,549 --> 00:25:58,720 designed it so it could be strong and 710 00:26:02,470 --> 00:26:00,559 light at the same time so we're 711 00:26:06,390 --> 00:26:02,480 very confident that whatever mars can 712 00:26:11,029 --> 00:26:09,669 well in your confidence we trust so uh 713 00:26:12,549 --> 00:26:11,039 we are going to take a couple more 714 00:26:14,070 --> 00:26:12,559 questions from the audience in just a 715 00:26:17,110 --> 00:26:14,080 moment for both of you 716 00:26:19,430 --> 00:26:17,120 but i have one final question for you 717 00:26:20,310 --> 00:26:19,440 is this part of the dream of working at 718 00:26:22,149 --> 00:26:20,320 jpl 719 00:26:23,990 --> 00:26:22,159 you get to be a part of a unique first 720 00:26:25,510 --> 00:26:24,000 of its kind mission is that why you come 721 00:26:26,789 --> 00:26:25,520 to work at a place like this 722 00:26:30,070 --> 00:26:26,799 and tim why don't you take that one 723 00:26:31,669 --> 00:26:30,080 first we're gonna pull up image eight 724 00:26:33,430 --> 00:26:31,679 well sure it is definitely a dream i 725 00:26:35,430 --> 00:26:33,440 grew up in small town america 726 00:26:37,110 --> 00:26:35,440 and i grew up reading all the national 727 00:26:37,990 --> 00:26:37,120 geographic issues about the voyager 728 00:26:39,990 --> 00:26:38,000 probe and all the different 729 00:26:42,789 --> 00:26:40,000 outer planets that have visited i love 730 00:26:44,549 --> 00:26:42,799 to consume all kinds of astronomy books 731 00:26:46,710 --> 00:26:44,559 and i was generally a computer geek so 732 00:26:48,549 --> 00:26:46,720 all this stuff came together really well 733 00:26:50,310 --> 00:26:48,559 and i was able to get a job out of 734 00:26:51,669 --> 00:26:50,320 college at jpl and do really exciting 735 00:26:53,110 --> 00:26:51,679 things which is really culminating in 736 00:26:55,029 --> 00:26:53,120 this chance to do 737 00:26:56,789 --> 00:26:55,039 a first of a kind thing on mars which is 738 00:26:58,390 --> 00:26:56,799 to fly a helicopter which has never been 739 00:26:59,990 --> 00:26:58,400 done before so sure 740 00:27:01,750 --> 00:27:00,000 we're very nervous but we're confident 741 00:27:02,390 --> 00:27:01,760 in our helicopter and we're excited to 742 00:27:06,390 --> 00:27:02,400 go 743 00:27:08,149 --> 00:27:06,400 and we're really looking forward to it 744 00:27:09,990 --> 00:27:08,159 and how about for you farah is this part 745 00:27:11,430 --> 00:27:10,000 of the dream of working at jpl for you 746 00:27:14,070 --> 00:27:11,440 as well 747 00:27:16,630 --> 00:27:14,080 absolutely so for me you know my story 748 00:27:19,669 --> 00:27:16,640 is that my first summer at jpl was the 749 00:27:21,350 --> 00:27:19,679 summer of 2012 and i was in interned 750 00:27:23,430 --> 00:27:21,360 and intern during graduate school and 751 00:27:24,950 --> 00:27:23,440 the summer of 2012 for those of you who 752 00:27:27,029 --> 00:27:24,960 are space fans is the summer that 753 00:27:29,110 --> 00:27:27,039 curiosity landed on mars 754 00:27:31,190 --> 00:27:29,120 and i still remember that moment in the 755 00:27:33,190 --> 00:27:31,200 auditorium it was like late on a sunday 756 00:27:33,990 --> 00:27:33,200 evening and i was super nervous with my 757 00:27:36,230 --> 00:27:34,000 friends watching 758 00:27:37,190 --> 00:27:36,240 watching the landing but what was so 759 00:27:40,549 --> 00:27:37,200 incredible as an 760 00:27:42,549 --> 00:27:40,559 intern is to be on lab and to see 761 00:27:44,950 --> 00:27:42,559 you see these incredible people 762 00:27:47,029 --> 00:27:44,960 achieving the impossible right 763 00:27:49,190 --> 00:27:47,039 who sends a massive rover to mars and 764 00:27:50,070 --> 00:27:49,200 lowers it from a skycrane on the surface 765 00:27:51,830 --> 00:27:50,080 of mars and 766 00:27:53,430 --> 00:27:51,840 who's crazy enough to do that apparently 767 00:27:56,070 --> 00:27:53,440 people at jpl and i thought 768 00:27:57,750 --> 00:27:56,080 i want to be one of those crazy people 769 00:27:58,950 --> 00:27:57,760 and that is really you know when that it 770 00:28:02,389 --> 00:27:58,960 started i 771 00:28:04,310 --> 00:28:02,399 i knocked on every manager's job with my 772 00:28:05,909 --> 00:28:04,320 door with my resume and i was like i 773 00:28:07,990 --> 00:28:05,919 want to work here this is what i want to 774 00:28:10,070 --> 00:28:08,000 do i want to be part of a team like this 775 00:28:12,549 --> 00:28:10,080 i want to do these things 776 00:28:14,310 --> 00:28:12,559 um so uh so i was lucky enough to get a 777 00:28:17,350 --> 00:28:14,320 job back in 2014 and 778 00:28:18,870 --> 00:28:17,360 and this is my second was mission but um 779 00:28:21,029 --> 00:28:18,880 but with this one it's really coming 780 00:28:21,669 --> 00:28:21,039 full circle right perseverance is sort 781 00:28:24,310 --> 00:28:21,679 of the 782 00:28:26,470 --> 00:28:24,320 the big sister or for curiosity and it's 783 00:28:29,669 --> 00:28:26,480 it is that next big mission and it's 784 00:28:31,350 --> 00:28:29,679 so cool to be able to say that i am now 785 00:28:32,950 --> 00:28:31,360 part of the team that's making history 786 00:28:34,710 --> 00:28:32,960 right like i'm part of that team that's 787 00:28:37,510 --> 00:28:34,720 doing crazy things on mars 788 00:28:39,430 --> 00:28:37,520 um and it's it's super humbling too to 789 00:28:40,950 --> 00:28:39,440 have like come full circle that way and 790 00:28:43,750 --> 00:28:40,960 be part of that team and 791 00:28:44,950 --> 00:28:43,760 and what's special with ingenuity is you 792 00:28:47,750 --> 00:28:44,960 know with other missions 793 00:28:49,510 --> 00:28:47,760 at jpl we've had other rovers before so 794 00:28:50,710 --> 00:28:49,520 often when we have problems 795 00:28:52,230 --> 00:28:50,720 you know there's always someone to call 796 00:28:54,149 --> 00:28:52,240 we can call the person that did it on 797 00:28:56,870 --> 00:28:54,159 curiosity and ask like you know we have 798 00:28:58,789 --> 00:28:56,880 a similar problem here can you help me 799 00:29:00,470 --> 00:28:58,799 not the case with ingenuity no one's 800 00:29:02,149 --> 00:29:00,480 done this before there's no textbook 801 00:29:04,070 --> 00:29:02,159 there's no one to call 802 00:29:05,669 --> 00:29:04,080 we just gotta figure it out and that 803 00:29:07,350 --> 00:29:05,679 that is sort of like the best 804 00:29:09,190 --> 00:29:07,360 piece of engineering right there right 805 00:29:10,710 --> 00:29:09,200 like we we have to figure it out we 806 00:29:12,950 --> 00:29:10,720 figure it out as a team we 807 00:29:14,549 --> 00:29:12,960 come up with creative solutions and and 808 00:29:17,029 --> 00:29:14,559 you know we're we're the ones writing 809 00:29:19,190 --> 00:29:17,039 the textbooks right and and eventually 810 00:29:21,350 --> 00:29:19,200 i can't wait one day when you know 811 00:29:22,870 --> 00:29:21,360 hopefully that this all goes well and 812 00:29:24,470 --> 00:29:22,880 and you know when they will be the ones 813 00:29:25,590 --> 00:29:24,480 getting the phone calls will be the ones 814 00:29:27,029 --> 00:29:25,600 that people are going to 815 00:29:30,630 --> 00:29:27,039 reach out to when they want to fly the 816 00:29:33,830 --> 00:29:32,470 really incredible groundbreaking work 817 00:29:36,470 --> 00:29:33,840 that you both are doing 818 00:29:37,909 --> 00:29:36,480 and i am sure that social media is 819 00:29:39,750 --> 00:29:37,919 lighting up with questions 820 00:29:41,430 --> 00:29:39,760 for those of you that are still watching 821 00:29:42,870 --> 00:29:41,440 uh with us please make sure you put 822 00:29:44,549 --> 00:29:42,880 those in the chat 823 00:29:46,310 --> 00:29:44,559 and our social media team will bring 824 00:29:49,269 --> 00:29:46,320 them to us as quickly as possible 825 00:29:52,070 --> 00:29:49,279 we'll answer as many as we can sarah 826 00:29:54,549 --> 00:29:52,080 how's it looking out there 827 00:29:56,230 --> 00:29:54,559 oh there's plenty there's plenty can i 828 00:29:58,549 --> 00:29:56,240 ask one right now 829 00:29:59,590 --> 00:29:58,559 please no i gotta clear my deck here 830 00:30:02,070 --> 00:29:59,600 great um 831 00:30:02,710 --> 00:30:02,080 okay i don't know if his name is brian 832 00:30:05,190 --> 00:30:02,720 or brain 833 00:30:05,830 --> 00:30:05,200 i kind of hope it's brain but it's uh on 834 00:30:08,470 --> 00:30:05,840 linkedin 835 00:30:10,630 --> 00:30:08,480 uh this is a question for you tim how 836 00:30:11,990 --> 00:30:10,640 did you simulate the low gravity and low 837 00:30:15,350 --> 00:30:12,000 atmospheric pressure 838 00:30:17,750 --> 00:30:15,360 during testing on earth 839 00:30:19,669 --> 00:30:17,760 well jpl along with being a place that 840 00:30:21,029 --> 00:30:19,679 has cool spacecraft it also has cool 841 00:30:23,510 --> 00:30:21,039 ways to test things 842 00:30:25,510 --> 00:30:23,520 so there's a chamber at jpl it's 25 feet 843 00:30:26,789 --> 00:30:25,520 across and 70 feet high 844 00:30:29,190 --> 00:30:26,799 and they've used it for years for 845 00:30:31,029 --> 00:30:29,200 spacecraft to pump down 846 00:30:32,870 --> 00:30:31,039 and pump out the air to get it to either 847 00:30:34,870 --> 00:30:32,880 a pure vacuum or in our case we 848 00:30:36,070 --> 00:30:34,880 we pumped it down to one percent of 849 00:30:38,310 --> 00:30:36,080 earth's density 850 00:30:39,669 --> 00:30:38,320 so that's where the helicopter will fly 851 00:30:41,269 --> 00:30:39,679 so that's how we're able to get the 852 00:30:42,950 --> 00:30:41,279 equivalent atmosphere 853 00:30:44,389 --> 00:30:42,960 and we had some very clever engineers 854 00:30:44,870 --> 00:30:44,399 that came up with the design we called 855 00:30:47,750 --> 00:30:44,880 it our 856 00:30:48,389 --> 00:30:47,760 gravity offload mechanism and it was a 857 00:30:50,789 --> 00:30:48,399 it was a 858 00:30:52,389 --> 00:30:50,799 special computerized system that had a 859 00:30:53,750 --> 00:30:52,399 tether or a big cable that would come 860 00:30:54,789 --> 00:30:53,760 down and attach to the top of the 861 00:30:57,509 --> 00:30:54,799 helicopter 862 00:30:59,269 --> 00:30:57,519 and literally pull it up in a way that 863 00:31:01,350 --> 00:30:59,279 would simulate mars gravity 864 00:31:03,509 --> 00:31:01,360 so that way we had this chamber that 865 00:31:03,830 --> 00:31:03,519 could simu both simulate mars gravity 866 00:31:07,269 --> 00:31:03,840 and 867 00:31:09,350 --> 00:31:07,279 that's where we did 868 00:31:14,549 --> 00:31:09,360 almost three years of testing to get the 869 00:31:17,509 --> 00:31:16,310 that's uh quite a bit of dedication i 870 00:31:19,190 --> 00:31:17,519 mean you've already showcased that 871 00:31:20,789 --> 00:31:19,200 tonight how dedicated you've been but 872 00:31:22,470 --> 00:31:20,799 three years of testing that's quite 873 00:31:23,830 --> 00:31:22,480 dedicated sarah we've got time for a few 874 00:31:26,950 --> 00:31:23,840 more questions 875 00:31:27,909 --> 00:31:26,960 great excellent okay um this one is for 876 00:31:30,149 --> 00:31:27,919 you pharah 877 00:31:31,509 --> 00:31:30,159 uh pedro on linkedin so a lot of 878 00:31:32,149 --> 00:31:31,519 questions from linkedin tonight this is 879 00:31:34,789 --> 00:31:32,159 great 880 00:31:36,789 --> 00:31:34,799 um how will perseverance track ingenuity 881 00:31:40,230 --> 00:31:36,799 in the sky is there a beacon 882 00:31:41,590 --> 00:31:40,240 or object recognition that's a great 883 00:31:44,470 --> 00:31:41,600 question pedro so 884 00:31:45,350 --> 00:31:44,480 um so actually what we do is that we can 885 00:31:46,710 --> 00:31:45,360 localize 886 00:31:49,110 --> 00:31:46,720 the helicopter and we're going to keep 887 00:31:51,830 --> 00:31:49,120 track of where it is on the ground 888 00:31:53,590 --> 00:31:51,840 and then based on uh based on what we 889 00:31:55,350 --> 00:31:53,600 think the flights are going to be like 890 00:31:57,269 --> 00:31:55,360 we're going to set off field of view 891 00:31:58,630 --> 00:31:57,279 while enough on our cameras to be able 892 00:32:00,630 --> 00:31:58,640 to catch the flight so 893 00:32:02,470 --> 00:32:00,640 so when we drop off the helicopter we'll 894 00:32:03,190 --> 00:32:02,480 know exactly where it is and we'll have 895 00:32:05,750 --> 00:32:03,200 you know we keep 896 00:32:07,509 --> 00:32:05,760 really good maps of mars when we drive 897 00:32:08,470 --> 00:32:07,519 so we'll have a map of where we are and 898 00:32:11,190 --> 00:32:08,480 where it is 899 00:32:12,950 --> 00:32:11,200 and then as we drive away from it uh 900 00:32:15,430 --> 00:32:12,960 we'll be augmenting those maps and 901 00:32:17,509 --> 00:32:15,440 relocalizing using images every time so 902 00:32:18,710 --> 00:32:17,519 think of it as like i've set a pin on a 903 00:32:20,870 --> 00:32:18,720 map and i try and 904 00:32:22,149 --> 00:32:20,880 point back to it and based on my images 905 00:32:24,549 --> 00:32:22,159 i can sort of 906 00:32:26,230 --> 00:32:24,559 adjust a little bit what the error might 907 00:32:28,470 --> 00:32:26,240 be you know in my 908 00:32:30,230 --> 00:32:28,480 my position or what i think my position 909 00:32:33,029 --> 00:32:30,240 might be with the helicopter so 910 00:32:34,549 --> 00:32:33,039 so even at 100 meters away we'll know 911 00:32:36,470 --> 00:32:34,559 where the helicopter is and we'll be 912 00:32:37,909 --> 00:32:36,480 able to image it before its flight so we 913 00:32:39,269 --> 00:32:37,919 know exactly where it is 914 00:32:41,430 --> 00:32:39,279 and then the morning of that first 915 00:32:43,350 --> 00:32:41,440 flight for example we'll point all our 916 00:32:45,110 --> 00:32:43,360 cameras at it we have multiple cameras 917 00:32:46,549 --> 00:32:45,120 and we'll wait eagerly and we 918 00:32:48,549 --> 00:32:46,559 we're even going to take a video 919 00:32:49,350 --> 00:32:48,559 hopefully of the flight and then we 920 00:32:51,990 --> 00:32:49,360 should see that 921 00:32:53,509 --> 00:32:52,000 that helicopter um in our field of view 922 00:32:55,269 --> 00:32:53,519 and then when we're done and it lands 923 00:32:55,990 --> 00:32:55,279 we'll be able to relocalize again and 924 00:33:02,389 --> 00:32:56,000 figure out 925 00:33:09,029 --> 00:33:06,630 okay for tim here oh sorry about that i 926 00:33:10,870 --> 00:33:09,039 didn't mean to jump out there but i'm 927 00:33:14,470 --> 00:33:10,880 going in i'm going in 928 00:33:16,630 --> 00:33:14,480 great kirk on facebook um 929 00:33:18,470 --> 00:33:16,640 i thought this is for you tim uh does 930 00:33:21,509 --> 00:33:18,480 the helicopter have any smarts 931 00:33:23,830 --> 00:33:21,519 to adjust if its flight model is not 932 00:33:24,710 --> 00:33:23,840 exactly what it's discovering on mars 933 00:33:27,110 --> 00:33:24,720 basically is the 934 00:33:30,549 --> 00:33:27,120 can the helicopter make adjustments or 935 00:33:33,110 --> 00:33:30,559 learn learn along the way 936 00:33:34,950 --> 00:33:33,120 well certainly the software is we did a 937 00:33:37,509 --> 00:33:34,960 lot of testing on the flight algorithms 938 00:33:38,630 --> 00:33:37,519 we have a very talented guidance control 939 00:33:40,310 --> 00:33:38,640 team 940 00:33:42,149 --> 00:33:40,320 and they built the software to follow a 941 00:33:44,310 --> 00:33:42,159 set of waypoints so before the flight we 942 00:33:46,149 --> 00:33:44,320 get together as a team and we plan 943 00:33:47,830 --> 00:33:46,159 where we want the flight to go and then 944 00:33:49,029 --> 00:33:47,840 the software on board will take those 945 00:33:51,029 --> 00:33:49,039 waypoints 946 00:33:53,430 --> 00:33:51,039 and fly that trajectory and the software 947 00:33:54,870 --> 00:33:53,440 has the built-in smarts to adjust to 948 00:33:57,269 --> 00:33:54,880 environmental conditions it might 949 00:33:59,509 --> 00:33:57,279 encounter like gusts of wind 950 00:34:00,389 --> 00:33:59,519 or you know just deviations in the 951 00:34:02,310 --> 00:34:00,399 flight path it's 952 00:34:03,590 --> 00:34:02,320 it's very well designed to bring it back 953 00:34:05,350 --> 00:34:03,600 into alignment 954 00:34:07,669 --> 00:34:05,360 with the path that we had planned for it 955 00:34:09,190 --> 00:34:07,679 so that was part of the new 956 00:34:11,190 --> 00:34:09,200 development that we did for this project 957 00:34:14,069 --> 00:34:11,200 is they designed all new brand new 958 00:34:15,669 --> 00:34:14,079 algorithms that can handle the martian 959 00:34:17,829 --> 00:34:15,679 environment plus this mission that we 960 00:34:21,030 --> 00:34:17,839 gave it to fly along these trajectories 961 00:34:22,950 --> 00:34:21,040 and do what it needs to do because it's 962 00:34:24,629 --> 00:34:22,960 not only flying based on an inertial 963 00:34:25,909 --> 00:34:24,639 sensor it has a camera system that 964 00:34:28,470 --> 00:34:25,919 points downward 965 00:34:29,510 --> 00:34:28,480 we're taking pictures 30 times a second 966 00:34:31,510 --> 00:34:29,520 looking at features 967 00:34:33,669 --> 00:34:31,520 inside the camera the image of the 968 00:34:35,510 --> 00:34:33,679 camera and then track those features 969 00:34:37,829 --> 00:34:35,520 from frame to frame 970 00:34:39,669 --> 00:34:37,839 and that's how the helicopter is able to 971 00:34:41,190 --> 00:34:39,679 know which direction it's going and how 972 00:34:43,589 --> 00:34:41,200 fast along with the 973 00:34:45,190 --> 00:34:43,599 inertial sensor and even an altimeter so 974 00:34:52,869 --> 00:34:45,200 it's a pretty sophisticated little robot 975 00:34:56,629 --> 00:34:54,710 we have time for some more questions 976 00:35:00,630 --> 00:34:56,639 sarah so feel free to ask a couple 977 00:35:02,150 --> 00:35:00,640 of ways okay this is also for them 978 00:35:04,230 --> 00:35:02,160 because this is a little bit about 979 00:35:05,829 --> 00:35:04,240 the helicopter team and so i know that 980 00:35:06,790 --> 00:35:05,839 you've been on the helicopter team for a 981 00:35:09,270 --> 00:35:06,800 long time 982 00:35:10,150 --> 00:35:09,280 um so rhonda on facebook is wondering 983 00:35:13,349 --> 00:35:10,160 first of all how 984 00:35:15,030 --> 00:35:13,359 big the helicopter team is and then um 985 00:35:16,470 --> 00:35:15,040 sort of a related question from 986 00:35:19,109 --> 00:35:16,480 white-tailed jedi 987 00:35:20,390 --> 00:35:19,119 on youtube is who gets to pilot the 988 00:35:23,430 --> 00:35:20,400 helicopter every day 989 00:35:25,349 --> 00:35:23,440 how do you choose oh that's a great 990 00:35:27,109 --> 00:35:25,359 question so we had a team i would say at 991 00:35:29,190 --> 00:35:27,119 our peak we were probably 30 or 40 992 00:35:30,790 --> 00:35:29,200 different people all bringing different 993 00:35:33,349 --> 00:35:30,800 kinds of talents to the table 994 00:35:34,870 --> 00:35:33,359 i'm here because i'm representing 995 00:35:37,190 --> 00:35:34,880 operations but there's many other 996 00:35:39,589 --> 00:35:37,200 talented people on the project who did 997 00:35:41,109 --> 00:35:39,599 mechanical design the thermal design the 998 00:35:43,670 --> 00:35:41,119 power design 999 00:35:45,430 --> 00:35:43,680 and when you mention the pilot our chief 1000 00:35:48,150 --> 00:35:45,440 pilot hovard grip 1001 00:35:50,150 --> 00:35:48,160 is a very talented uh guidance engineer 1002 00:35:52,790 --> 00:35:50,160 he even flies planes for 1003 00:35:54,470 --> 00:35:52,800 fun so he's a naturally gifted guy for 1004 00:35:55,670 --> 00:35:54,480 doing this and he's the one 1005 00:35:57,670 --> 00:35:55,680 with his team that are going to be 1006 00:36:00,950 --> 00:35:57,680 planning each one of the flights 1007 00:36:02,710 --> 00:36:00,960 and so that's how it works is is 1008 00:36:04,310 --> 00:36:02,720 the guidance team gives me the path they 1009 00:36:07,190 --> 00:36:04,320 want to follow we 1010 00:36:09,270 --> 00:36:07,200 enter it into a series of commands that 1011 00:36:10,550 --> 00:36:09,280 that file of commands we give to far and 1012 00:36:11,430 --> 00:36:10,560 her team and they beam it up to the 1013 00:36:15,349 --> 00:36:11,440 rover 1014 00:36:16,150 --> 00:36:15,359 the helicopter and executes it and then 1015 00:36:26,230 --> 00:36:16,160 we 1016 00:36:27,990 --> 00:36:26,240 chew our fingernails to the bone 1017 00:36:29,910 --> 00:36:28,000 okay here's another question why don't 1018 00:36:33,510 --> 00:36:29,920 you try and take this pharah 1019 00:36:35,430 --> 00:36:33,520 um gabriel on linkedin is asking 1020 00:36:37,510 --> 00:36:35,440 so how does communication between the 1021 00:36:40,069 --> 00:36:37,520 mars instruments get affected 1022 00:36:41,349 --> 00:36:40,079 by the lack of the magnetic field that 1023 00:36:44,630 --> 00:36:41,359 is on mars 1024 00:36:46,710 --> 00:36:44,640 and um does the solar radiation 1025 00:36:49,589 --> 00:36:46,720 um affect the communication between the 1026 00:36:52,550 --> 00:36:49,599 helicopter and the rover 1027 00:36:54,470 --> 00:36:52,560 so we obviously you know the environment 1028 00:36:56,150 --> 00:36:54,480 on mars is is different from the one on 1029 00:36:57,990 --> 00:36:56,160 earth but one of the things that we did 1030 00:37:00,150 --> 00:36:58,000 on earth before we went to mars is that 1031 00:37:01,109 --> 00:37:00,160 we actually tested that communication we 1032 00:37:03,910 --> 00:37:01,119 do something called 1033 00:37:06,230 --> 00:37:03,920 electromagnetic interference testing and 1034 00:37:08,550 --> 00:37:06,240 so we put the rover in a special chamber 1035 00:37:09,430 --> 00:37:08,560 that's quiet like mars or as quiet as we 1036 00:37:11,190 --> 00:37:09,440 can get it 1037 00:37:12,550 --> 00:37:11,200 and um and one of the things that we had 1038 00:37:14,470 --> 00:37:12,560 to do actually is 1039 00:37:17,349 --> 00:37:14,480 we had to figure out if there were any 1040 00:37:18,870 --> 00:37:17,359 instruments on the rover like when we're 1041 00:37:20,710 --> 00:37:18,880 changing or switching things on the 1042 00:37:22,470 --> 00:37:20,720 rover whether any of that 1043 00:37:23,750 --> 00:37:22,480 magnetic noise that's created when you 1044 00:37:25,750 --> 00:37:23,760 use those instruments 1045 00:37:27,670 --> 00:37:25,760 might affect the link between the 1046 00:37:29,510 --> 00:37:27,680 helicopter and the rover 1047 00:37:31,430 --> 00:37:29,520 and so you know we're talking from the 1048 00:37:33,510 --> 00:37:31,440 helicopter to the rover using a radio 1049 00:37:34,950 --> 00:37:33,520 that has a certain signal and we want to 1050 00:37:36,310 --> 00:37:34,960 make sure that there's not noise in that 1051 00:37:38,150 --> 00:37:36,320 signal created by 1052 00:37:39,910 --> 00:37:38,160 other instruments on board and we 1053 00:37:40,950 --> 00:37:39,920 actually found that there's a few 1054 00:37:42,470 --> 00:37:40,960 instruments that 1055 00:37:44,790 --> 00:37:42,480 uh for example if we're moving our 1056 00:37:46,630 --> 00:37:44,800 motors that that creates just enough 1057 00:37:48,710 --> 00:37:46,640 noise that we can lose communication 1058 00:37:51,190 --> 00:37:48,720 with the rover we can lose packets 1059 00:37:53,030 --> 00:37:51,200 um so that's why we do that kind of 1060 00:37:54,630 --> 00:37:53,040 testing before we go so that we kind of 1061 00:37:57,349 --> 00:37:54,640 understand the behavior 1062 00:37:59,430 --> 00:37:57,359 and then when we get to mars um we're 1063 00:38:00,790 --> 00:37:59,440 gonna sort of restrict certain the usage 1064 00:38:02,630 --> 00:38:00,800 of certain things like we won't be 1065 00:38:04,230 --> 00:38:02,640 moving our arm all over while we're 1066 00:38:04,790 --> 00:38:04,240 talking to the helicopter so that we 1067 00:38:07,510 --> 00:38:04,800 know that 1068 00:38:08,950 --> 00:38:07,520 we can get a clean signal that way so um 1069 00:38:09,910 --> 00:38:08,960 so yeah it's definitely a test that 1070 00:38:12,069 --> 00:38:09,920 every single 1071 00:38:14,710 --> 00:38:12,079 um spacecraft goes through it's one of 1072 00:38:16,630 --> 00:38:14,720 the key tests that we do before launch 1073 00:38:18,790 --> 00:38:16,640 to figure out what's compatible with 1074 00:38:21,109 --> 00:38:18,800 what and make sure that we can 1075 00:38:27,030 --> 00:38:21,119 we can successfully communicate with our 1076 00:38:34,550 --> 00:38:31,990 okay do we have time for another one yep 1077 00:38:36,069 --> 00:38:34,560 you got it ron on linkedin is asking 1078 00:38:38,870 --> 00:38:36,079 will the helicopter 1079 00:38:39,829 --> 00:38:38,880 attempt to land atop higher elevation 1080 00:38:42,390 --> 00:38:39,839 features 1081 00:38:45,670 --> 00:38:42,400 or typically always return nearby the 1082 00:38:49,109 --> 00:38:45,680 rover i guess that's for you pharah 1083 00:38:50,950 --> 00:38:49,119 so um right now the plan is to is to 1084 00:38:52,630 --> 00:38:50,960 land at the same place so what we've 1085 00:38:54,390 --> 00:38:52,640 done or what we're doing on mars right 1086 00:38:57,430 --> 00:38:54,400 now is we're trying to identify 1087 00:38:59,910 --> 00:38:57,440 a flight zone so it's an area that's 1088 00:39:00,870 --> 00:38:59,920 about 30 meters across and about 100 1089 00:39:02,710 --> 00:39:00,880 meter long 1090 00:39:04,069 --> 00:39:02,720 and that is going to be our stage to 1091 00:39:05,829 --> 00:39:04,079 play on that's that's where the 1092 00:39:07,829 --> 00:39:05,839 helicopter is allowed to fly 1093 00:39:09,109 --> 00:39:07,839 and within that there's a little there's 1094 00:39:10,470 --> 00:39:09,119 an area that we might 1095 00:39:12,710 --> 00:39:10,480 you know that we're going to identify or 1096 00:39:14,390 --> 00:39:12,720 try and find that we'll have you know 1097 00:39:15,750 --> 00:39:14,400 we're looking for a flat area with 1098 00:39:18,150 --> 00:39:15,760 hardly any rocks 1099 00:39:19,589 --> 00:39:18,160 uh where the helicopter can land that's 1100 00:39:21,349 --> 00:39:19,599 kind of it's like landing pad right like 1101 00:39:21,990 --> 00:39:21,359 so if you have a helicopter on earth and 1102 00:39:24,069 --> 00:39:22,000 you 1103 00:39:25,670 --> 00:39:24,079 it can only really land in that flat 1104 00:39:27,990 --> 00:39:25,680 area with a big h on it 1105 00:39:29,910 --> 00:39:28,000 that's that's going to be our helicopter 1106 00:39:31,349 --> 00:39:29,920 on mars no big h but you know we'll have 1107 00:39:33,510 --> 00:39:31,359 our area where we're gonna 1108 00:39:35,030 --> 00:39:33,520 um be able to drop our helicopter and 1109 00:39:37,910 --> 00:39:35,040 fly to and from there so 1110 00:39:39,750 --> 00:39:37,920 so the goal is to is to always return to 1111 00:39:41,910 --> 00:39:39,760 that home base and then from there do 1112 00:39:43,349 --> 00:39:41,920 increasingly more complicated flights so 1113 00:39:45,430 --> 00:39:43,359 at the beginning we'll just go up and 1114 00:39:47,589 --> 00:39:45,440 down and then we'll go across 1115 00:39:49,430 --> 00:39:47,599 and then we'll see maybe uh maybe the 1116 00:39:49,670 --> 00:39:49,440 team the helicopter team will get sporty 1117 00:39:53,430 --> 00:39:49,680 and 1118 00:39:55,670 --> 00:39:53,440 current plan 1119 00:39:59,190 --> 00:39:55,680 but for now we're planning on landing at 1120 00:40:02,310 --> 00:40:00,630 break for you the current plan that's 1121 00:40:03,430 --> 00:40:02,320 that's brave i like that i like that 1122 00:40:05,510 --> 00:40:03,440 exciting supporting 1123 00:40:06,550 --> 00:40:05,520 there we've got time for just a couple 1124 00:40:11,030 --> 00:40:06,560 more questions 1125 00:40:13,589 --> 00:40:11,040 probably about two more okay 1126 00:40:14,390 --> 00:40:13,599 all right angelica from linkedin she's 1127 00:40:16,630 --> 00:40:14,400 getting it 1128 00:40:18,630 --> 00:40:16,640 um this for you tim so what is the 1129 00:40:22,390 --> 00:40:18,640 actual flight goal of the vehicle 1130 00:40:24,390 --> 00:40:22,400 um is it flight time is it distance 1131 00:40:25,910 --> 00:40:24,400 and is there a particular forward 1132 00:40:29,589 --> 00:40:25,920 velocity that um 1133 00:40:34,710 --> 00:40:32,950 well since this is a kind of a new a new 1134 00:40:36,309 --> 00:40:34,720 mission we've never done this before the 1135 00:40:37,910 --> 00:40:36,319 primary objective of this 1136 00:40:39,510 --> 00:40:37,920 mission is to characterize what it's 1137 00:40:40,950 --> 00:40:39,520 like to fly on mars 1138 00:40:43,349 --> 00:40:40,960 so we're going to be doing as far as 1139 00:40:45,430 --> 00:40:43,359 said a series of these increasingly 1140 00:40:47,349 --> 00:40:45,440 aggressive flights and we take lots of 1141 00:40:49,750 --> 00:40:47,359 data during those flights 1142 00:40:51,589 --> 00:40:49,760 and we analyze that data on the ground 1143 00:40:53,430 --> 00:40:51,599 to see how it performed 1144 00:40:55,270 --> 00:40:53,440 and then that's the kind of data that 1145 00:40:56,870 --> 00:40:55,280 will feed forward into future possible 1146 00:40:59,589 --> 00:40:56,880 helicopters that can do more 1147 00:41:02,150 --> 00:40:59,599 and have greater capability and so 1148 00:41:04,870 --> 00:41:02,160 that's really the objective is to 1149 00:41:07,030 --> 00:41:04,880 is to test how well it flies and so 1150 00:41:08,630 --> 00:41:07,040 we'll be doing these increasingly harder 1151 00:41:10,150 --> 00:41:08,640 flights to stress the system a little 1152 00:41:12,550 --> 00:41:10,160 more each time 1153 00:41:14,069 --> 00:41:12,560 and see you know how the data comes back 1154 00:41:15,430 --> 00:41:14,079 when we do those flights 1155 00:41:17,270 --> 00:41:15,440 and how it responds to those various 1156 00:41:19,750 --> 00:41:17,280 things in the environment like wind 1157 00:41:21,589 --> 00:41:19,760 and altitude and we're going to fly it 1158 00:41:23,030 --> 00:41:21,599 about five meters high 1159 00:41:24,950 --> 00:41:23,040 we're a little bit limited by our 1160 00:41:26,150 --> 00:41:24,960 altimeter the how far down it can see 1161 00:41:27,750 --> 00:41:26,160 and the camera system 1162 00:41:29,349 --> 00:41:27,760 so it'll be about five meters high and 1163 00:41:30,790 --> 00:41:29,359 we'll be flying two to three meters per 1164 00:41:32,069 --> 00:41:30,800 second horizontally when we do our 1165 00:41:33,510 --> 00:41:32,079 horizontal flights 1166 00:41:35,670 --> 00:41:33,520 so it's not going to exactly buzz the 1167 00:41:37,510 --> 00:41:35,680 tower so to speak but it's going to be 1168 00:41:39,109 --> 00:41:37,520 you know it's going to be faster than a 1169 00:41:41,670 --> 00:41:39,119 rover that's one of the promises of a 1170 00:41:43,670 --> 00:41:41,680 vehicle like this is that the rover 1171 00:41:45,430 --> 00:41:43,680 potentially could see a feature in the 1172 00:41:46,069 --> 00:41:45,440 distance that it thinks is very cool but 1173 00:41:47,990 --> 00:41:46,079 it could take 1174 00:41:49,510 --> 00:41:48,000 days or even a week to get there and 1175 00:41:51,030 --> 00:41:49,520 something like a helicopter could fly 1176 00:41:53,349 --> 00:41:51,040 over there in just a few 1177 00:41:55,349 --> 00:41:53,359 tens of seconds and analyze and inspect 1178 00:41:56,550 --> 00:41:55,359 it so that's part of what this mission 1179 00:41:58,710 --> 00:41:56,560 is about is to 1180 00:42:00,630 --> 00:41:58,720 do this groundbreaking work to see how 1181 00:42:03,750 --> 00:42:00,640 well it performs on mars so that 1182 00:42:07,589 --> 00:42:03,760 future generations of helicopters can do 1183 00:42:11,510 --> 00:42:09,670 i like that even more cool things in the 1184 00:42:12,309 --> 00:42:11,520 future and speaking of things in the 1185 00:42:15,030 --> 00:42:12,319 future we have 1186 00:42:17,430 --> 00:42:15,040 one final question sarah for our 1187 00:42:19,670 --> 00:42:17,440 speakers tonight 1188 00:42:21,109 --> 00:42:19,680 okay let's take it from facebook from 1189 00:42:23,750 --> 00:42:21,119 matt on facebook 1190 00:42:24,790 --> 00:42:23,760 asks will imagery from the helicopter be 1191 00:42:28,150 --> 00:42:24,800 used to help 1192 00:42:32,230 --> 00:42:28,160 percy navigate the martian terrain as it 1193 00:42:36,150 --> 00:42:34,950 and i can take that one so so thank you 1194 00:42:37,910 --> 00:42:36,160 i should have said that's probably a 1195 00:42:41,190 --> 00:42:37,920 good one for you 1196 00:42:42,390 --> 00:42:41,200 got the personality connection um in the 1197 00:42:45,349 --> 00:42:42,400 nominal plan 1198 00:42:45,829 --> 00:42:45,359 no um so what we're learning again at 1199 00:42:51,510 --> 00:42:45,839 tim 1200 00:42:52,870 --> 00:42:51,520 paving the way for future helicopters 1201 00:42:53,750 --> 00:42:52,880 for future missions we want to 1202 00:42:55,750 --> 00:42:53,760 demonstrate 1203 00:42:57,430 --> 00:42:55,760 that you know that helicopters can fly 1204 00:42:59,510 --> 00:42:57,440 on mars and and by the way 1205 00:43:01,190 --> 00:42:59,520 rovers started as technology 1206 00:43:03,030 --> 00:43:01,200 demonstrations too we had 1207 00:43:05,190 --> 00:43:03,040 that's where we started you know a small 1208 00:43:05,589 --> 00:43:05,200 team came up with a small rover on mars 1209 00:43:10,230 --> 00:43:05,599 and 1210 00:43:12,069 --> 00:43:10,240 right so 1211 00:43:13,430 --> 00:43:12,079 so we're really hoping that one day 1212 00:43:16,230 --> 00:43:13,440 ingenuity will be 1213 00:43:17,670 --> 00:43:16,240 that stepping stone also for for bigger 1214 00:43:20,309 --> 00:43:17,680 um helicopters but 1215 00:43:21,270 --> 00:43:20,319 but in this in this case you know the 1216 00:43:23,990 --> 00:43:21,280 the area 1217 00:43:25,589 --> 00:43:24,000 that um that ingenuity is flying over is 1218 00:43:27,589 --> 00:43:25,599 one that we've already imaged we 1219 00:43:29,190 --> 00:43:27,599 actually wanted to assess that area to 1220 00:43:31,829 --> 00:43:29,200 make sure that it was safe 1221 00:43:33,750 --> 00:43:31,839 um so that you know if if ingenuity 1222 00:43:35,430 --> 00:43:33,760 needs to do an emergency landing for 1223 00:43:37,030 --> 00:43:35,440 example we know that it's a safe area 1224 00:43:38,309 --> 00:43:37,040 that it doesn't have big boulders and 1225 00:43:40,550 --> 00:43:38,319 things like that so 1226 00:43:42,069 --> 00:43:40,560 so again at least you know per the 1227 00:43:44,309 --> 00:43:42,079 current playbook and who knows 1228 00:43:46,069 --> 00:43:44,319 what you know what the um what the team 1229 00:43:47,510 --> 00:43:46,079 is going to decide to do once 1230 00:43:49,349 --> 00:43:47,520 you know if we are successful with those 1231 00:43:51,109 --> 00:43:49,359 first few flights but for the first two 1232 00:43:53,349 --> 00:43:51,119 flights at least it's it's going to be 1233 00:43:55,030 --> 00:43:53,359 an area that we've already imaged 1234 00:43:57,030 --> 00:43:55,040 but it definitely is going to be really 1235 00:43:58,630 --> 00:43:57,040 interesting right to look at 1236 00:44:00,069 --> 00:43:58,640 the path that it takes and the images 1237 00:44:01,670 --> 00:44:00,079 that it takes and compare that to what 1238 00:44:02,950 --> 00:44:01,680 we know about the surface and 1239 00:44:05,510 --> 00:44:02,960 again that's going to help us learn 1240 00:44:07,430 --> 00:44:05,520 about what it what it's like to fly on 1241 00:44:09,510 --> 00:44:07,440 mars and and what it takes so 1242 00:44:10,710 --> 00:44:09,520 um so it's definitely you know going to 1243 00:44:13,750 --> 00:44:10,720 be something that we're looking forward 1244 00:44:18,390 --> 00:44:16,309 great ability to develop new technology 1245 00:44:19,589 --> 00:44:18,400 uh thanks for those wonderful questions 1246 00:44:21,030 --> 00:44:19,599
