00:03:52,440 --> 00:03:47,290 so 7 00:04:12,869 --> 00:04:06,960 [Music] 8 00:05:22,070 --> 00:04:28,290 this do 9 00:05:26,150 --> 00:05:24,310 often you get to say you work next to a 10 00:05:26,629 --> 00:05:26,160 robotic system that's going to mars 11 00:05:27,990 --> 00:05:26,639 right 12 00:05:29,430 --> 00:05:28,000 there's not many places in the world 13 00:05:31,270 --> 00:05:29,440 that you can do this my name is eric 14 00:05:32,710 --> 00:05:31,280 aguilar and i'm working on a robotic 15 00:05:34,390 --> 00:05:32,720 system that will be collecting martian 16 00:05:36,230 --> 00:05:34,400 rock samples so it can be studied on 17 00:05:38,629 --> 00:05:36,240 earth this is our hexapod testbed it's 18 00:05:40,469 --> 00:05:38,639 basically a rover body that allows us to 19 00:05:42,310 --> 00:05:40,479 attach you know the robotic arm the 20 00:05:42,790 --> 00:05:42,320 adaptive caching assembly the drill so 21 00:05:44,629 --> 00:05:42,800 that's why 22 00:05:46,550 --> 00:05:44,639 a lot of the testing happens uh behind 23 00:05:48,870 --> 00:05:46,560 me the sample caching system will 24 00:05:50,310 --> 00:05:48,880 use a robotic arm and drill to actually 25 00:05:52,390 --> 00:05:50,320 take samples out of the ground 26 00:05:54,150 --> 00:05:52,400 and we're looking for evidence of life 27 00:05:55,990 --> 00:05:54,160 that may have existed on mars on the 28 00:05:57,830 --> 00:05:56,000 smaller arm that lives inside the valley 29 00:05:59,830 --> 00:05:57,840 of the rover and is used to actually 30 00:06:01,189 --> 00:05:59,840 process the tubes as they come back with 31 00:06:03,270 --> 00:06:01,199 a sample inside we'll 32 00:06:05,189 --> 00:06:03,280 measure it take some pictures of it and 33 00:06:05,990 --> 00:06:05,199 get it sealed and stored for a future 34 00:06:07,749 --> 00:06:06,000 mission to pick 35 00:06:09,350 --> 00:06:07,759 them up you see the robotic arm 36 00:06:11,270 --> 00:06:09,360 stretched out and we have a bunch of 37 00:06:13,990 --> 00:06:11,280 engineers and technicians working on 38 00:06:15,909 --> 00:06:14,000 installing a model of our drill work in 39 00:06:16,309 --> 00:06:15,919 aerospace that

00:12:39,040 the the idea is that if we can flush it 219 00:12:41,509 --> 00:12:41,040 out here we can fix it we can mitigate 220 00:12:46,470 --> 00:12:41,519 it 221 00:12:48,310 --> 00:12:46,480 we get to mars or our final destination 222 00:12:49,910 --> 00:12:48,320 we would know you know we have 223 00:12:52,150 --> 00:12:49,920 confidence that this thing is that 224 00:12:54,150 --> 00:12:52,160 our spacecraft's not going to work and 225 00:12:55,750 --> 00:12:54,160 so one of the issues that that i'll 226 00:12:58,550 --> 00:12:55,760 bring up that we've had recently 227 00:13:00,389 --> 00:12:58,560 or over over the time with developing 228 00:13:03,430 --> 00:13:00,399 the sample caching system 229 00:13:06,790 --> 00:13:03,440 is within the robot is is in the um 230 00:13:08,870 --> 00:13:06,800 the drill on the drill um we have these 231 00:13:11,670 --> 00:13:08,880 uh ball lock mechanisms 232 00:13:12,150 --> 00:13:11,680 um that are uh used to hold the the 233 00:13:15,430 --> 00:13:12,160 drill 234 00:13:18,230 --> 00:13:15,440 know sort of as 235 00:13:19,190 --> 00:13:18,240 a gripping mechanism now when we're 236 00:13:21,509 --> 00:13:19,200 working with 237 00:13:23,350 --> 00:13:21,519 you know uh rocks you're gonna have fine 238 00:13:24,470 --> 00:13:23,360 powder and as you're as you're drilling 239 00:13:25,590 --> 00:13:24,480 into the rocks you're gonna have this 240 00:13:30,310 --> 00:13:25,600 fine powder 241 00:13:32,550 --> 00:13:30,320 and and and creep into crevices 242 00:13:33,509 --> 00:13:32,560 it's almost like uh you know when you go 243 00:13:35,110 --> 00:13:33,519 hiking 244 00:13:36,389 --> 00:13:35,120 and you start walking you start walking 245 00:13:37,750 --> 00:13:36,399 the trails and you start to kind of 246 00:13:40,790 --> 00:13:37,760 climb higher and higher into 247 00:13:42,470 --> 00:13:40,800 into your into your mountain trail um 248 00:13:44,069 --> 00:13:42,480 you're gonna you start to find out that 249 00:13:45,910 --> 00:13:44,079 you know your your hiking boots might 250 00:13:47,990 --> 00:13:45,920 actually get a little bit caked of 251 00:13:49,670 --> 00:13:48,000 of some of this finer dust as it as it 252 00:13:50,710 --> 00:13:49,680 kind of sits in there and gets in these 253 00:13:51,990 --> 00:13:50,720 crevices 254 00:13:55,189 --> 00:13:52,000 makes it for your shoes to be a little 255 00:13:57,509 --> 00:13:55,199 slippier uh uh slippery 256 00:13:59,030 --> 00:13:57,519 so what you do is you know is before you 257 00:14:01,590 --> 00:13:59,040 go on a narrow part of the 258 00:14:02,629 --> 00:14:01,600 of the uh hike or of the trail you're 259 00:14:04,550 --> 00:14:02,639 gonna tend to 260 00:14:05,750 --> 00:14:04,560 kind of kick your shoes a little bit and 261 00:14:07,829 --> 00:14:05,760 get that dust off and 262 00:14:09,670 --> 00:14:07,839 and that way it gives you a nice clean 263 00:14:11,509 --> 00:14:09,680 grip and you're back to where where you 264 00:14:13,430 --> 00:14:11,519 wanted it to be with your shoes 265 00:14:15,350 --> 00:14:13,440 so imagine the same thing where you have 266 00:14:17,430 --> 00:14:15,360 this powder that's flowing 267 00:14:19,509 --> 00:14:17,440 as we're interacting with rocks and and 268 00:14:22,790 --> 00:14:19,519 you've got a dusty and mars environment 269 00:14:23,590 --> 00:14:22,800 we have this really fine powder uh dirt 270 00:14:25,750 --> 00:14:23,600 that has been 271 00:14:27,430 --> 00:14:25,760 uh you know kind of being pushed around 272 00:14:28,949 --> 00:14:27,440 and circulating around the drill as 273 00:14:30,790 --> 00:14:28,959 we're operating it 274 00:14:32,389 --> 00:14:30,800 while this powder is getting into some 275 00:14:33,590 --> 00:14:32,399 of the crevices around the ball locks 276 00:14:36,790 --> 00:14:33,600 which is not letting them 277 00:14:38,790 --> 00:14:36,800 move as freely as as we like so 278 00:14:40,470 --> 00:14:38,800 when and during one of our tests we were 279 00:14:43,030 --> 00:14:40,480 trying to go and pick up a bit and we 280 00:14:45,189 --> 00:14:43,040 were unable to get past the ball locks 281 00:14:47,189 --> 00:14:45,199 we eventually can show that if we push 282 00:14:48,629 --> 00:14:47,199 on it hard enough it'll work but we want 283 00:14:50,710 --> 00:14:48,639 to understand 284 00:14:52,550 --> 00:14:50,720 why were the ball locks not free as we 285 00:14:55,110 --> 00:14:52,560 would have liked them to be so 286 00:14:55,910 --> 00:14:55,120 you know we're able to break our chamber 287 00:14:59,189 --> 00:14:55,920 and 288 00:15:00,870 --> 00:14:59,199 take a look inside 289 00:15:02,710 --> 00:15:00,880 and as we look inside we notice that 290 00:15:03,189 --> 00:15:02,720 there's this uh fine fine powder 291 00:15:05,990 --> 00:15:03,199 material 292 00:15:06,710 --> 00:15:06,000 around the ball locks and we we realized 293 00:15:10,470 --> 00:15:06,720 that well 294 00:15:13,509 --> 00:15:10,480 we we have a mitigation mitigation plan 295 00:15:15,990 --> 00:15:13,519 already that we can employ one of which 296 00:15:19,189 --> 00:15:16,000 is we call the percussive cleaning 297 00:15:20,870 --> 00:15:19,199 we bring when we get to mars one of the 298 00:15:22,470 --> 00:15:20,880 early things that we're going to do on 299 00:15:24,069 --> 00:15:22,480 the surface is to 300 00:15:25,509 --> 00:15:24,079 get the drill and do a percussive 301 00:15:27,350 --> 00:15:25,519 cleaning which is using the hammer 302 00:15:30,150 --> 00:15:27,360 that's built into the drill 303 00:15:31,350 --> 00:15:30,160 to sort of shake shake loose any any 304 00:15:32,629 --> 00:15:31,360 loose particulates 305 00:15:35,110 --> 00:15:32,639 that may have traveled with us from 306 00:15:36,389 --> 00:15:35,120 earth to mars and get it off the drill 307 00:15:37,829 --> 00:15:36,399 before we start trying to do any 308 00:15:40,069 --> 00:15:37,839 sampling 309 00:15:42,310 --> 00:15:40,079 and then so we decided that we're going 310 00:15:44,470 --> 00:15:42,320 to use that similar approach 311 00:15:47,189 --> 00:15:44,480 on the drill to help clear out any of 312 00:15:48,790 --> 00:15:47,199 this fine powder from these ball locks 313 00:15:50,629 --> 00:15:48,800 once we did that we're able to get the 314 00:15:50,949 --> 00:15:50,639 ball locks to actually operate back into 315 00:15:54,470 --> 00:15:50,959 the 316 00:15:55,910 --> 00:15:54,480 into a i'll say a clean state um to and 317 00:15:58,629 --> 00:15:55,920 they moved there freely again 318 00:16:00,230 --> 00:15:58,639 so it was something that uh um that we 319 00:16:02,550 --> 00:16:00,240 discovered here because we needed to 320 00:16:05,350 --> 00:16:02,560 really interact with the rocks to see it 321 00:16:06,310 --> 00:16:05,360 um and it's now something in our in our 322 00:16:09,430 --> 00:16:06,320 repertoire to 323 00:16:11,430 --> 00:16:09,440 to fix as or to to use while we're 324 00:16:13,509 --> 00:16:11,440 on the surface to help mitigate this 325 00:16:15,749 --> 00:16:13,519 issue 326 00:16:17,590 --> 00:16:15,759 and someone on social media actually has 327 00:16:20,230 --> 00:16:17,600 a really good follow-up question to that 328 00:16:21,350 --> 00:16:20,240 abdul on facebook wants to know is the 329 00:16:25,430 --> 00:16:21,360 martian ground 330 00:16:27,829 --> 00:16:25,440 sand or clay it's actually a 331 00:16:28,870 --> 00:16:27,839 mixture right um so there's actually a 332 00:16:31,670 --> 00:16:28,880 wide range of 333 00:16:33,509 --> 00:16:31,680 of uh types of rocks that we uh that we 334 00:16:34,470 --> 00:16:33,519 interact with there's there are clays 335 00:16:38,230 --> 00:16:34,480 for sure 336 00:16:41,990 --> 00:16:38,240 um there are um some some mudstones 337 00:16:44,389 --> 00:16:42,000 uh which is more like a clay uh 338 00:16:45,829 --> 00:16:44,399 uh you know harder harder rocks we also 339 00:16:47,430 --> 00:16:45,839 have regolith which is just you know 340 00:16:50,230 --> 00:16:47,440 like a scent you know sand 341 00:16:52,150 --> 00:16:50,240 uh consistency that you might see so we 342 00:16:53,030 --> 00:16:52,160 actually have a wide range of rocks that 343 00:16:54,790 --> 00:16:53,040 we have to 344 00:16:56,230 --> 00:16:54,800 be able to interact with and to take 345 00:16:58,470 --> 00:16:56,240 samples so 346 00:16:59,430 --> 00:16:58,480 we've actually developed uh algorithms 347 00:17:03,509 --> 00:16:59,440 to 348 00:17:05,029 --> 00:17:03,519 samples up 349 00:17:07,429 --> 00:17:05,039 too much as we're as we're trying to 350 00:17:09,429 --> 00:17:07,439 take a core sample so depending on how 351 00:17:10,789 --> 00:17:09,439 hard or soft the rock is 352 00:17:13,029 --> 00:17:10,799 we'll change our spindle and our 353 00:17:16,230 --> 00:17:13,039 percussive percussive frequency 354 00:17:18,630 --> 00:17:16,240 uh to adapt to the to the varying uh 355 00:17:21,270 --> 00:17:18,640 uh uh types of rocks that we might 356 00:17:26,710 --> 00:17:24,549 and tracy on facebook wants to know more 357 00:17:28,549 --> 00:17:26,720 about the samples that she wants to know 358 00:17:32,230 --> 00:17:28,559 will perseverance actually bring 359 00:17:34,630 --> 00:17:32,240 samples back to earth right so 360 00:17:35,430 --> 00:17:34,640 perseverance is not the return mission 361 00:17:38,549 --> 00:17:35,440 so our 362 00:17:40,549 --> 00:17:38,559 our job is to actually go and collect 363 00:17:41,510 --> 00:17:40,559 the samples whether it's a regolith or 364 00:17:44,549 --> 00:17:41,520 sand 365 00:17:46,630 --> 00:17:44,559 material or or actual rock samples 366 00:17:47,830 --> 00:17:46,640 once we actually take the rock sample 367 00:17:50,310 --> 00:17:47,840 out of the ground 368 00:17:52,630 --> 00:17:50,320 we'll then hermetically seal the tube 369 00:17:55,750 --> 00:17:52,640 the tube will eventually be dropped off 370 00:17:57,990 --> 00:17:55,760 um at a site where a future mission 371 00:17:59,350 --> 00:17:58,000 um would be able to come and pick it up 372 00:18:01,190 --> 00:17:59,360 and and uh 373 00:18:02,470 --> 00:18:01,200 you know potentially bring the samples 374 00:18:05,190 --> 00:18:02,480 back um but 375 00:18:06,070 --> 00:18:05,200 our job is to actually uh collect the 376 00:18:07,590 --> 00:18:06,080 sample 377 00:18:09,190 --> 00:18:07,600 and keep it hermetic and make it 378 00:18:09,830 --> 00:18:09,200 hermetically sealed for a future 379 00:18:13,590 --> 00:18:09,840 mission's 380 00:18:13,990 --> 00:18:13,600 return then emily on facebook wants to 381 00:18:15,510 --> 00:18:14,000 know 382 00:18:17,669 --> 00:18:15,520 about that will the collection 383 00:18:18,950 --> 00:18:17,679 techniques for perseverance on mars be 384 00:18:22,789 --> 00:18:18,960 similar to the way 385 00:18:24,950 --> 00:18:22,799 osiris-rex sampled bennu 386 00:18:27,430 --> 00:18:24,960 uh no it's it's a little bit different 387 00:18:28,070 --> 00:18:27,440 um so we're actually taking a coring 388 00:18:31,110 --> 00:18:28,080 drill 389 00:18:32,070 --> 00:18:31,120 to to go up to about 70 millimeters deep 390 00:18:35,190 --> 00:18:32,080 into the 391 00:18:37,590 --> 00:18:35,200 right so 392 00:18:38,230 --> 00:18:37,600 we're actually planning on taking core 393 00:18:40,710 --> 00:18:38,240 samples 394 00:18:41,990 --> 00:18:40,720 out of the ground whereas i think in 395 00:18:45,029 --> 00:18:42,000 osiris-rex it's 396 00:18:45,350 --> 00:18:45,039 more of a uh they do some ingestion of 397 00:18:52,789 --> 00:18:45,360 the 398 00:18:53,430 --> 00:18:52,799 um ours is to actually um we will do 399 00:18:55,590 --> 00:18:53,440 some 400 00:18:57,830 --> 00:18:55,600 science ahead of time so we know which 401 00:18:59,190 --> 00:18:57,840 rocks we want to pick up and sample 402 00:19:01,350 --> 00:18:59,200 but we're actually going to go in and 403 00:19:03,909 --> 00:19:01,360 take a sample out of the ground 404 00:19:07,110 --> 00:19:03,919 um it's it's probably about the the 405 00:19:09,750 --> 00:19:07,120 width of your pinky or at least my pinky 406 00:19:10,310 --> 00:19:09,760 um and and you know about that that size 407 00:19:12,070 --> 00:19:10,320 too is 408 00:19:15,029 --> 00:19:12,080 as far as uh you know how much sample 409 00:19:17,110 --> 00:19:15,039 we're going to get out of the ground 410 00:19:18,630 --> 00:19:17,120 never thought of it that way before and 411 00:19:20,710 --> 00:19:18,640 thank you emily for 412 00:19:21,990 --> 00:19:20,720 keeping track of several missions at 413 00:19:24,950 --> 00:19:22,000 once too 414 00:19:26,710 --> 00:19:24,960 and now we have sandy on facebook asking 415 00:19:28,310 --> 00:19:26,720 what will we be able to learn about the 416 00:19:30,230 --> 00:19:28,320 samples collected 417 00:19:33,270 --> 00:19:30,240 prior to bringing the samples back to 418 00:19:34,870 --> 00:19:33,280 earth for further study 419 00:19:37,510 --> 00:19:34,880 uh so we have a couple different 420 00:19:40,710 --> 00:19:37,520 instruments that we'll be doing 421 00:19:41,510 --> 00:19:40,720 x-ray uh spectroscopy um to actually 422 00:19:44,710 --> 00:19:41,520 determine 423 00:19:45,990 --> 00:19:44,720 um what sort of uh content might be in 424 00:19:47,830 --> 00:19:46,000 those rocks right so 425 00:19:49,510 --> 00:19:47,840 um the idea is that we're gonna go 426 00:19:52,390 --> 00:19:49,520 around and we are gonna look 427 00:19:52,870 --> 00:19:52,400 you know at different rock samples now 428 00:19:55,510 --> 00:19:52,880 right 429 00:19:57,270 --> 00:19:55,520 rocks may have different shapes and may 430 00:19:58,070 --> 00:19:57,280 look a little bit different based on on 431 00:20:00,310 --> 00:19:58,080 where they're at 432 00:20:01,270 --> 00:20:00,320 and and but some of the chemical 433 00:20:03,430 --> 00:20:01,280 composition 434 00:20:04,950 --> 00:20:03,440 may be the same between between rocks 435 00:20:06,230 --> 00:20:04,960 that look look different 436 00:20:08,149 --> 00:20:06,240 so the idea is that we're going to 437 00:20:10,149 --> 00:20:08,159 actually go ahead and and we will do 438 00:20:11,750 --> 00:20:10,159 potentially in a braided patch first 439 00:20:12,310 --> 00:20:11,760 where we might clear off some of the 440 00:20:14,870 --> 00:20:12,320 initial 441 00:20:15,750 --> 00:20:14,880 i'll say the weathering um that that's 442 00:20:18,789 --> 00:20:15,760 happened on 443 00:20:19,669 --> 00:20:18,799 on mars over the time and get down and 444 00:20:21,350 --> 00:20:19,679 make uh 445 00:20:23,430 --> 00:20:21,360 make a judgment on whether or not we 446 00:20:26,230 --> 00:20:23,440 actually want uh that rock 447 00:20:27,110 --> 00:20:26,240 so um the scientists have a whole uh 448 00:20:29,750 --> 00:20:27,120 collection of 449 00:20:30,710 --> 00:20:29,760 of uh of instruments that they're gonna 450 00:20:32,950 --> 00:20:30,720 use to 451 00:20:36,390 --> 00:20:32,960 to pick up uh you know decide which 452 00:20:40,870 --> 00:20:39,350 and then this one is from maikiki and it 453 00:20:43,110 --> 00:20:40,880 kind of goes back to what we first 454 00:20:43,909 --> 00:20:43,120 touched on they ask did you always have 455 00:20:46,630 --> 00:20:43,919 a love for 456 00:20:49,510 --> 00:20:46,640 jet propulsion and or the aerospace 457 00:20:51,750 --> 00:20:49,520 engineering industry 458 00:20:53,110 --> 00:20:51,760 so so i'll be a little embarrassed on 459 00:20:56,710 --> 00:20:53,120 this one right i think 460 00:20:59,430 --> 00:20:56,720 my initial love was aerospace because i 461 00:21:01,270 --> 00:20:59,440 didn't know that the jet propulsion 462 00:21:02,070 --> 00:21:01,280 existed in the way it does today right 463 00:21:05,750 --> 00:21:02,080 so 464 00:21:07,830 --> 00:21:05,760 uh now that i'm at jpl it's 465 00:21:09,029 --> 00:21:07,840 you know by far this is this is where i 466 00:21:11,430 --> 00:21:09,039 want it to be 467 00:21:12,950 --> 00:21:11,440 uh nowhere else right so this is this is 468 00:21:17,430 --> 00:21:12,960 one of those things where 469 00:21:19,669 --> 00:21:17,440 you know i just didn't know i was not as 470 00:21:20,470 --> 00:21:19,679 as kid into you know the different 471 00:21:22,310 --> 00:21:20,480 centers and 472 00:21:23,669 --> 00:21:22,320 and what everybody does but you know the 473 00:21:26,310 --> 00:21:23,679 work that we do here the 474 00:21:27,669 --> 00:21:26,320 the our ability to be hands-on and work 475 00:21:29,270 --> 00:21:27,679 and design and 476 00:21:31,590 --> 00:21:29,280 and build and get your hands dirty that 477 00:21:34,710 --> 00:21:31,600 that's what really makes it for me so um 478 00:21:36,470 --> 00:21:34,720 yeah so i you know as much as i'd like 479 00:21:39,430 --> 00:21:36,480 to say jpl was always my 480 00:21:41,430 --> 00:21:39,440 my go-to my number one it i just i just 481 00:21:43,350 --> 00:21:41,440 wasn't aware of it when i was first 482 00:21:44,630 --> 00:21:43,360 getting out of college and and looking 483 00:21:47,110 --> 00:21:44,640 around so 484 00:21:48,470 --> 00:21:47,120 um so yeah so sorry i guess aerospace 485 00:21:51,669 --> 00:21:48,480 but 486 00:21:54,549 --> 00:21:51,679 you know jpl opened my eyes to to the 487 00:21:56,070 --> 00:21:54,559 how fun this work could really be it's 488 00:21:58,149 --> 00:21:56,080 okay admitting that you didn't know 489 00:21:59,350 --> 00:21:58,159 lots of kids that are watching right now 490 00:22:01,590 --> 00:21:59,360 might wonder 491 00:22:03,830 --> 00:22:01,600 how do you get involved or how do you 492 00:22:05,510 --> 00:22:03,840 learn about the different types 493 00:22:07,510 --> 00:22:05,520 of engineering that's involved in the 494 00:22:10,710 --> 00:22:07,520 industry 495 00:22:12,390 --> 00:22:10,720 well i mean the thing is is you know 496 00:22:14,149 --> 00:22:12,400 there's probably every type of 497 00:22:17,110 --> 00:22:14,159 engineering that you can imagine is 498 00:22:18,230 --> 00:22:17,120 and and science is is part of part of 499 00:22:21,029 --> 00:22:18,240 jpl 500 00:22:21,990 --> 00:22:21,039 um you know i i know that i've talked to 501 00:22:25,350 --> 00:22:22,000 people that 502 00:22:26,789 --> 00:22:25,360 develop software um you know electrical 503 00:22:27,350 --> 00:22:26,799 engineering of course mechanical 504 00:22:30,149 --> 00:22:27,360 engineering 505 00:22:31,029 --> 00:22:30,159 aerospace um you know chemical 506 00:22:33,110 --> 00:22:31,039 engineering 507 00:22:34,549 --> 00:22:33,120 you know from you know chemists to 508 00:22:36,630 --> 00:22:34,559 physicists 509 00:22:38,149 --> 00:22:36,640 you know i think we probably hit the 510 00:22:39,990 --> 00:22:38,159 range i don't know that there's an 511 00:22:42,070 --> 00:22:40,000 engineering discipline 512 00:22:45,029 --> 00:22:42,080 that you can probably ask is is this one 513 00:22:48,230 --> 00:22:45,039 that's relevant to jpl then we'd say no 514 00:22:49,510 --> 00:22:48,240 because we do rely on on outside you 515 00:22:50,149 --> 00:22:49,520 know thinking out of the box and 516 00:22:54,070 --> 00:22:50,159 bringing in 517 00:22:55,669 --> 00:22:54,080 outside i'll say views into 518 00:22:57,750 --> 00:22:55,679 into solving some of these problems 519 00:22:58,310 --> 00:22:57,760 they're not all just kind of black and 520 00:23:00,310 --> 00:22:58,320 white and 521 00:23:02,230 --> 00:23:00,320 purely mechanical pretty electrical as 522 00:23:03,350 --> 00:23:02,240 robotics i mean it's it's all over the 523 00:23:05,830 --> 00:23:03,360 place and 524 00:23:07,510 --> 00:23:05,840 and um so i don't know that there's a a 525 00:23:09,350 --> 00:23:07,520 bad engineering it's more 526 00:23:10,950 --> 00:23:09,360 making sure you do something that you 527 00:23:12,630 --> 00:23:10,960 really enjoy 528 00:23:14,230 --> 00:23:12,640 because that's where when you really 529 00:23:15,669 --> 00:23:14,240 enjoy what you're doing that's where the 530 00:23:18,310 --> 00:23:15,679 work really shines 531 00:23:19,830 --> 00:23:18,320 and that's where we're able to to you 532 00:23:22,630 --> 00:23:19,840 know to really show that 533 00:23:24,470 --> 00:23:22,640 you know how exceptional or work can be 534 00:23:26,390 --> 00:23:24,480 because i think everybody that that does 535 00:23:28,470 --> 00:23:26,400 a work here really enjoys 536 00:23:31,110 --> 00:23:28,480 um you know their their engineering and 537 00:23:33,590 --> 00:23:31,120 they have a passion for what they do 538 00:23:37,830 --> 00:23:33,600 and then nabil on youtube wants to know 539 00:23:41,029 --> 00:23:37,840 how did you develop your soft skills 540 00:23:45,269 --> 00:23:41,039 oh a lot of trial and error it was 541 00:23:46,870 --> 00:23:45,279 uh you know i've i've had to uh you know 542 00:23:48,549 --> 00:23:46,880 work with teams right we always work 543 00:23:51,190 --> 00:23:48,559 with teams um 544 00:23:53,190 --> 00:23:51,200 we work as a as a fairly large you know 545 00:23:55,510 --> 00:23:53,200 community of of engineers 546 00:23:56,950 --> 00:23:55,520 uh working to get things through and and 547 00:23:59,110 --> 00:23:56,960 you know over time 548 00:24:00,630 --> 00:23:59,120 you know i i've made my mistakes and you 549 00:24:01,590 --> 00:24:00,640 know maybe come down a little too hard 550 00:24:04,310 --> 00:24:01,600 on somebody or 551 00:24:05,909 --> 00:24:04,320 or vice versa and so i've learned and i 552 00:24:07,990 --> 00:24:05,919 i try to learn from 553 00:24:10,149 --> 00:24:08,000 other managers that i've worked for you 554 00:24:10,710 --> 00:24:10,159 know i i you know i may take a piece 555 00:24:15,350 --> 00:24:10,720 from 556 00:24:18,470 --> 00:24:15,360 and try to get that to sort of become 557 00:24:19,350 --> 00:24:18,480 mine and so yeah it's it's a it's a 558 00:24:21,669 --> 00:24:19,360 learned process 559 00:24:23,510 --> 00:24:21,679 and and uh you know one thing i think 560 00:24:25,269 --> 00:24:23,520 i've learned at jpl is we're not afraid 561 00:24:26,630 --> 00:24:25,279 to make mistakes or or to 562 00:24:29,110 --> 00:24:26,640 get something wrong we just want to 563 00:24:30,950 --> 00:24:29,120 learn from it uh and then move on 564 00:24:32,789 --> 00:24:30,960 and and and do better about it the next 565 00:24:34,870 --> 00:24:32,799 time so that's i think i'd say 566 00:24:35,830 --> 00:24:34,880 during date on the job and interacting 567 00:24:38,870 --> 00:24:35,840 with the teams and 568 00:24:39,750 --> 00:24:38,880 and and you know emulating some people 569 00:24:42,950 --> 00:24:39,760 that i admire 570 00:24:44,710 --> 00:24:42,960 at jpl that's great and 571 00:24:46,149 --> 00:24:44,720 liesel on youtube wants to know if you 572 00:24:49,350 --> 00:24:46,159 have any tips for women 573 00:24:50,070 --> 00:24:49,360 wanting to get into engineering well i 574 00:24:53,350 --> 00:24:50,080 mean 575 00:24:55,350 --> 00:24:53,360 you know it's same i'll say the same 576 00:24:56,630 --> 00:24:55,360 thing right is make sure you enjoy what 577 00:24:58,950 --> 00:24:56,640 you're doing 578 00:25:00,390 --> 00:24:58,960 um if you have the passion for it you 579 00:25:03,909 --> 00:25:00,400 know i know 580 00:25:07,190 --> 00:25:03,919 uh there's been a lot of uh you know 581 00:25:09,350 --> 00:25:07,200 you know females on my team for sure and 582 00:25:11,510 --> 00:25:09,360 you know i'll say you know they're just 583 00:25:13,750 --> 00:25:11,520 as good as everybody else right 584 00:25:15,990 --> 00:25:13,760 um oftentimes i feel you know that 585 00:25:19,990 --> 00:25:16,000 they're they come in and they bring in 586 00:25:23,110 --> 00:25:20,000 a a uh you know solid understanding of 587 00:25:24,230 --> 00:25:23,120 everything that we do um you know as as 588 00:25:26,390 --> 00:25:24,240 coming in and just 589 00:25:28,870 --> 00:25:26,400 just kicking butt right uh you know i'm 590 00:25:31,350 --> 00:25:28,880 a proud dad of two girls 591 00:25:32,070 --> 00:25:31,360 and i i can't wait to see them uh get 592 00:25:35,110 --> 00:25:32,080 out there and 593 00:25:38,549 --> 00:25:35,120 and make an impact this is great proud 594 00:25:42,310 --> 00:25:41,830 and how is testing coming along sc on 595 00:25:46,390 --> 00:25:42,320 youtube 596 00:25:49,190 --> 00:25:46,400 asks are you still testing right now 597 00:25:49,909 --> 00:25:49,200 yes um that's one thing i think that we 598 00:25:52,149 --> 00:25:49,919 always do 599 00:25:53,750 --> 00:25:52,159 right we test and test and test because 600 00:25:55,350 --> 00:25:53,760 we want to find 601 00:25:57,750 --> 00:25:55,360 all the corner cases we want to make 602 00:26:01,029 --> 00:25:57,760 sure this thing is going to work 603 00:26:03,190 --> 00:26:01,039 um you know when we go and an 604 00:26:04,789 --> 00:26:03,200 unknown environment right we don't know 605 00:26:07,510 --> 00:26:04,799 what we might encounter right 606 00:26:10,310 --> 00:26:07,520 um so we want to test we want to test as 607 00:26:11,909 --> 00:26:10,320 much as we can so we will be testing um 608 00:26:13,430 --> 00:26:11,919 you know our introducing and landing 609 00:26:15,430 --> 00:26:13,440 we're going to be testing that all the 610 00:26:17,430 --> 00:26:15,440 way into just about we land 611 00:26:19,110 --> 00:26:17,440 and and making sure that our our 612 00:26:20,310 --> 00:26:19,120 software our sensors everything is 613 00:26:22,950 --> 00:26:20,320 robust to 614 00:26:24,230 --> 00:26:22,960 to anything that we might see coming in 615 00:26:26,149 --> 00:26:24,240 additionally 616 00:26:27,510 --> 00:26:26,159 you know we have a bunch of we have 617 00:26:29,110 --> 00:26:27,520 rocks that we're still 618 00:26:31,190 --> 00:26:29,120 working and testing with our sample 619 00:26:33,110 --> 00:26:31,200 caching system we're still making 620 00:26:33,990 --> 00:26:33,120 progress there and we're still trying to 621 00:26:35,669 --> 00:26:34,000 define 622 00:26:37,430 --> 00:26:35,679 you know all the corner cases and making 623 00:26:39,350 --> 00:26:37,440 sure that that there's nothing that can 624 00:26:41,909 --> 00:26:39,360 surprise us on mars we want to 625 00:26:44,470 --> 00:26:41,919 you know often times we try to stress 626 00:26:46,630 --> 00:26:44,480 the the system out and get to its 627 00:26:48,630 --> 00:26:46,640 um you know three times life on things 628 00:26:51,190 --> 00:26:48,640 that move we want to make sure that 629 00:26:52,549 --> 00:26:51,200 if it was designed for to last a year 630 00:26:54,390 --> 00:26:52,559 that we can we can actually 631 00:26:56,870 --> 00:26:54,400 operate it for three years to make sure 632 00:26:59,269 --> 00:26:56,880 that we have a robust design that 633 00:27:01,350 --> 00:26:59,279 that can complete the mission as planned 634 00:27:04,149 --> 00:27:01,360 so yeah we always test and and 635 00:27:05,590 --> 00:27:04,159 um you know like i said this is uh you 636 00:27:05,990 --> 00:27:05,600 know something that we do all the time 637 00:27:09,110 --> 00:27:06,000 right we 638 00:27:09,510 --> 00:27:09,120 really just plow through and and and 639 00:27:14,870 --> 00:27:09,520 test 640 00:27:16,470 --> 00:27:14,880 we ever get tired of that 641 00:27:18,870 --> 00:27:16,480 catherine has a perfect follow-up 642 00:27:21,029 --> 00:27:18,880 question for that on facebook she asks 643 00:27:21,990 --> 00:27:21,039 when designing and engineering this 644 00:27:24,870 --> 00:27:22,000 project 645 00:27:25,909 --> 00:27:24,880 were the same ideas used from curiosity 646 00:27:29,909 --> 00:27:25,919 or do you start it 647 00:27:33,909 --> 00:27:29,919 all from scratch that's a good question 648 00:27:34,389 --> 00:27:33,919 this mission was curiosity was a basis 649 00:27:39,990 --> 00:27:34,399 for 650 00:27:41,669 --> 00:27:40,000 try to do is we try to we try to reuse a 651 00:27:43,909 --> 00:27:41,679 lot of the electronics and some 652 00:27:45,430 --> 00:27:43,919 and you know some of the hardware uh the 653 00:27:48,950 --> 00:27:45,440 mechanical structures that we could 654 00:27:51,190 --> 00:27:48,960 we could fit um and part of it was 655 00:27:52,389 --> 00:27:51,200 um you know we're getting to the point 656 00:27:54,870 --> 00:27:52,399 on our current 657 00:27:56,630 --> 00:27:54,880 technology of how big we can actually 658 00:27:58,950 --> 00:27:56,640 have these rovers what's the mass that 659 00:28:01,590 --> 00:27:58,960 we can safely land on another planet 660 00:28:03,029 --> 00:28:01,600 um and so we want to kind of stay within 661 00:28:05,110 --> 00:28:03,039 those constraints 662 00:28:06,310 --> 00:28:05,120 the sample caching system however was 663 00:28:08,549 --> 00:28:06,320 was brand new 664 00:28:09,430 --> 00:28:08,559 so that was something that we had to 665 00:28:11,990 --> 00:28:09,440 develop from 666 00:28:14,149 --> 00:28:12,000 from scratch if you will um you know we 667 00:28:17,669 --> 00:28:14,159 did have the robotic arm and the drill 668 00:28:20,549 --> 00:28:17,679 or a version of the drill from from msl 669 00:28:21,909 --> 00:28:20,559 my mark science laboratory um but we 670 00:28:22,950 --> 00:28:21,919 actually had to make improvements on 671 00:28:25,669 --> 00:28:22,960 that to make sure 672 00:28:27,430 --> 00:28:25,679 um you know we were able to uh to meet 673 00:28:29,830 --> 00:28:27,440 the mission requirements right so 674 00:28:30,870 --> 00:28:29,840 every part of the sample caching system 675 00:28:33,590 --> 00:28:30,880 i would argue is 676 00:28:35,430 --> 00:28:33,600 is new whether in in redesigning and 677 00:28:36,149 --> 00:28:35,440 making it lighter like the robotic arm 678 00:28:38,630 --> 00:28:36,159 bed 679 00:28:39,350 --> 00:28:38,640 or making a more capable drill for for 680 00:28:41,190 --> 00:28:39,360 what we have 681 00:28:43,909 --> 00:28:41,200 for taking cores and of course all the 682 00:28:47,110 --> 00:28:43,919 adaptive cache and assembly 683 00:28:50,230 --> 00:28:47,120 hardware inside the rover and 684 00:28:54,310 --> 00:28:50,240 liesel on youtube asks can dust on mars 685 00:29:00,950 --> 00:28:57,510 uh i i would say 686 00:29:04,950 --> 00:29:00,960 arguably maybe um i i don't i 687 00:29:08,230 --> 00:29:04,960 we are typically all of our connectors 688 00:29:11,110 --> 00:29:08,240 wires cables um the belly pan 689 00:29:12,789 --> 00:29:11,120 everything is is sealed up with uh you 690 00:29:15,350 --> 00:29:12,799 know so it's going to have 691 00:29:16,470 --> 00:29:15,360 you know we may get some dust in there 692 00:29:18,630 --> 00:29:16,480 but the idea is that 693 00:29:19,990 --> 00:29:18,640 you know we you know we use uh like for 694 00:29:22,470 --> 00:29:20,000 the electronics 695 00:29:23,430 --> 00:29:22,480 um things are typically uh conformally 696 00:29:25,830 --> 00:29:23,440 coated 697 00:29:26,710 --> 00:29:25,840 um which means that there's a a thin 698 00:29:28,230 --> 00:29:26,720 film uh 699 00:29:30,470 --> 00:29:28,240 coating that gets added to all the 700 00:29:32,789 --> 00:29:30,480 electronics to keep things from like 701 00:29:35,269 --> 00:29:32,799 from any fog to enter and potentially 702 00:29:37,350 --> 00:29:35,279 damage electronics short something out 703 00:29:38,630 --> 00:29:37,360 um so that's that's the one thing is you 704 00:29:41,669 --> 00:29:38,640 know the dust might have an 705 00:29:45,029 --> 00:29:41,679 impact but i haven't really seen it much 706 00:29:47,350 --> 00:29:45,039 outside of uh gunking up 707 00:29:49,350 --> 00:29:47,360 gears and things of that nature not not 708 00:29:51,350 --> 00:29:49,360 so much on the electronics 709 00:29:52,630 --> 00:29:51,360 but again i you know i i don't know that 710 00:29:53,990 --> 00:29:52,640 i can say that for sure that 711 00:29:56,549 --> 00:29:54,000 dust will not have an impact on the 712 00:30:00,310 --> 00:29:56,559 electronics uh but yeah so it's a 713 00:30:02,470 --> 00:30:00,320 soft answer it works though i 714 00:30:03,909 --> 00:30:02,480 have a follow-up question too that they 715 00:30:06,950 --> 00:30:03,919 want to know does it ever get 716 00:30:10,470 --> 00:30:06,960 frustrating testing so much 717 00:30:13,350 --> 00:30:10,480 uh yes it does sometimes 718 00:30:14,789 --> 00:30:13,360 um because sometimes and sometimes it's 719 00:30:17,029 --> 00:30:14,799 because the problems come 720 00:30:18,549 --> 00:30:17,039 up and they're really hard to to figure 721 00:30:20,630 --> 00:30:18,559 out and diagnose 722 00:30:22,310 --> 00:30:20,640 uh you know coming to the root cause of 723 00:30:23,830 --> 00:30:22,320 the problem 724 00:30:25,669 --> 00:30:23,840 is sometimes you know extremely 725 00:30:27,269 --> 00:30:25,679 difficult and 726 00:30:28,950 --> 00:30:27,279 and so it gets a little frustrating 727 00:30:31,190 --> 00:30:28,960 sometimes and and uh 728 00:30:32,470 --> 00:30:31,200 but i know over over the years that i've 729 00:30:34,710 --> 00:30:32,480 been working there 730 00:30:37,430 --> 00:30:34,720 i've learned how to sort of take a step 731 00:30:39,909 --> 00:30:37,440 back from time to time and 732 00:30:41,590 --> 00:30:39,919 and just underst you know kind of take a 733 00:30:42,149 --> 00:30:41,600 step back and and take a breath and say 734 00:30:43,430 --> 00:30:42,159 okay 735 00:30:45,909 --> 00:30:43,440 this is what you're doing you're working 736 00:30:47,909 --> 00:30:45,919 on a rover that's about to go to mars 737 00:30:49,750 --> 00:30:47,919 okay take a deep breath now get back 738 00:30:51,510 --> 00:30:49,760 into it and and don't let this problem 739 00:30:54,389 --> 00:30:51,520 beat you right so 740 00:30:55,190 --> 00:30:54,399 that's one of the things that i think uh 741 00:30:56,950 --> 00:30:55,200 you know that 742 00:30:58,549 --> 00:30:56,960 yeah it gets frustrating sometimes but i 743 00:30:59,509 --> 00:30:58,559 think if we just all take a step back 744 00:31:01,430 --> 00:30:59,519 and a breath 745 00:31:02,549 --> 00:31:01,440 we can overcome these problems and in 746 00:31:05,110 --> 00:31:02,559 general you know 747 00:31:06,630 --> 00:31:05,120 we might have a problem that shows up um 748 00:31:08,470 --> 00:31:06,640 but typically we've already known about 749 00:31:11,269 --> 00:31:08,480 it and already ready to mitigate it as 750 00:31:13,269 --> 00:31:11,279 as it comes out so um so yeah it's a 751 00:31:17,269 --> 00:31:13,279 little frustrating sometimes 752 00:31:19,830 --> 00:31:17,279 it's to be prepared yeah 753 00:31:21,269 --> 00:31:19,840 the final question we have is what 754 00:31:22,950 --> 00:31:21,279 technical skills do you think are the 755 00:31:26,230 --> 00:31:22,960 most important especially now that 756 00:31:29,750 --> 00:31:26,240 you're leading such a huge project 757 00:31:33,190 --> 00:31:29,760 oh technical skills um you know i think 758 00:31:35,430 --> 00:31:33,200 i think one of the biggest things is 759 00:31:37,190 --> 00:31:35,440 is to rely on your team it's not so much 760 00:31:39,029 --> 00:31:37,200 a technical skill right 761 00:31:41,909 --> 00:31:39,039 my my expertise is electrical 762 00:31:43,110 --> 00:31:41,919 engineering integration and tests and 763 00:31:44,950 --> 00:31:43,120 and you know some of the system 764 00:31:47,669 --> 00:31:44,960 designing 765 00:31:48,389 --> 00:31:47,679 but i don't know everything you know and 766 00:31:50,389 --> 00:31:48,399 and uh 767 00:31:52,549 --> 00:31:50,399 i don't i i don't pretend to know 768 00:31:54,950 --> 00:31:52,559 everything so i i make sure that 769 00:31:56,310 --> 00:31:54,960 the team is comprised of folks that are 770 00:31:59,590 --> 00:31:56,320 willing to be collaborative 771 00:32:00,549 --> 00:31:59,600 and want to work together and and as a 772 00:32:02,870 --> 00:32:00,559 team 773 00:32:04,789 --> 00:32:02,880 we come together and and and make the 774 00:32:06,389 --> 00:32:04,799 right choices and and oftentimes you 775 00:32:07,669 --> 00:32:06,399 know i i may have to make the last 776 00:32:10,310 --> 00:32:07,679 decision on something 777 00:32:10,950 --> 00:32:10,320 before it goes to my boss to to decide 778 00:32:14,310 --> 00:32:10,960 um 779 00:32:16,389 --> 00:32:14,320 and so it's it's the ability to you know 780 00:32:18,470 --> 00:32:16,399 understand the different points of views 781 00:32:20,630 --> 00:32:18,480 uh try to synthesize all that and then 782 00:32:22,070 --> 00:32:20,640 and then make a good decision 783 00:32:23,750 --> 00:32:22,080 that you know it's beneficial to the 784 00:32:25,830 --> 00:32:23,760 project and not just you know 785 00:32:27,110 --> 00:32:25,840 uh you know set aside because that's the 786 00:32:28,310 --> 00:32:27,120 way i want to do it or i just don't 787 00:32:30,710 --> 00:32:28,320 understand something 788 00:32:32,470 --> 00:32:30,720 so you know i think i really i don't 789 00:32:34,230 --> 00:32:32,480 know if there's any real 790 00:32:35,590 --> 00:32:34,240 technical stuff i mean when when it 791 00:32:37,509 --> 00:32:35,600 comes to electrical stuff 792 00:32:39,669 --> 00:32:37,519 electrical engineering i am definitely 793 00:32:42,389 --> 00:32:39,679 there and and providing my opinion 794 00:32:43,110 --> 00:32:42,399 and and where we're at but when it comes 795 00:32:44,950 --> 00:32:43,120 to 796 00:32:47,269 --> 00:32:44,960 you know potentially a mechanical 797 00:32:49,190 --> 00:32:47,279 failure that you know i have to rely on 798 00:32:50,389 --> 00:32:49,200 on on the folks on my team that are 799 00:32:52,630 --> 00:32:50,399 experts or uh 800 00:32:54,549 --> 00:32:52,640 in that area to help uh guide the 801 00:32:57,430 --> 00:32:54,559 decision process right so 802 00:32:58,630 --> 00:32:57,440 um i don't know if it's if it's just you 803 00:33:00,310 --> 00:32:58,640 know one 804 00:33:01,909 --> 00:33:00,320 it is technical to actually be able to 805 00:33:03,990 --> 00:33:01,919 understand everything but it's more 806 00:33:05,750 --> 00:33:04,000 uh i'll say it goes back to some of the 807 00:33:08,549 --> 00:33:05,760 soft skills as being able to 808 00:33:08,870 --> 00:33:08,559 uh synthesize all that and and come to a 809 00:33:14,310 --> 00:33:08,880 good 810 00:33:15,430 --> 00:33:14,320 wrap up all the questions thank you for 811 00:33:17,430 --> 00:33:15,440 your questions at home 812 00:33:19,190 --> 00:33:17,440 and thank you so much for joining us 813 00:33:22,230 --> 00:33:19,200 today eric 814 00:33:24,470 --> 00:33:22,240 thank you raquel and the rover 815 00:33:27,269 --> 00:33:24,480 is currently on its way to mars and set 816 00:33:30,149 --> 00:33:27,279 to land on the red planet on february 18 817 00:33:31,909 --> 00:33:30,159 2021 for the latest on the mission 818 00:33:33,909 --> 00:33:31,919 follow at nasa persevere 819 00:33:36,070 --> 00:33:33,919 on twitter and facebook and you can 820 00:33:37,269 --> 00:33:36,080 watch all of the behind the spacecraft 821 00:33:40,470 --> 00:33:37,279 video profiles
