soil could you 35 00:01:44,139 --> 00:01:41,749 bring up the first slide please snap 36 00:01:46,389 --> 00:01:44,149 will be joining our 19 operational 37 00:01:48,760 --> 00:01:46,399 satellites which along with air and 38 00:01:51,639 --> 00:01:48,770 ground sensors monitor the Earth's vital 39 00:01:56,739 --> 00:01:51,649 signs so that we can address issues like 40 00:01:59,919 --> 00:01:56,749 whether climate change fresh water water 41 00:02:01,719 --> 00:01:59,929 hazards and its really kind of exciting 42 00:02:04,450 --> 00:02:01,729 that we're launching this in the UN year 43 00:02:07,359 --> 00:02:04,460 of the soil because we have a large 44 00:02:09,669 --> 00:02:07,369 number of international organizations 45 00:02:12,039 --> 00:02:09,679 that have volunteered to support the 46 00:02:13,480 --> 00:02:12,049 SMAP project from countries such as 47 00:02:20,410 --> 00:02:13,490 Kenya oh 48 00:02:23,950 --> 00:02:20,420 raelia canada and and argentina they are 49 00:02:26,380 --> 00:02:23,960 going to be helping us assess the verify 50 00:02:28,690 --> 00:02:26,390 the algorithms and do data collection to 51 00:02:31,000 --> 00:02:28,700 support that activity and help us to 52 00:02:34,500 --> 00:02:31,010 analyze the massive amounts of data that 53 00:02:40,900 --> 00:02:38,920 soil moisture is a key part of the three 54 00:02:44,140 --> 00:02:40,910 cycles that support life on this planet 55 00:02:47,410 --> 00:02:44,150 the water cycle the energy cycle and the 56 00:02:52,330 --> 00:02:47,420 carbon cycle and these things affect 57 00:02:56,440 --> 00:02:52,340 human interests flood drought disease 58 00:03:01,960 --> 00:02:56,450 control weather if you would run the 59 00:03:03,910 --> 00:03:01,970 video please SMAP has two instruments on 60 00:03:05,530 --> 00:03:03,920 it an active instrument which is the 61 00:03:08,410 --> 00:03:05,540 radar which we've providing 62 00:03:10,480 --> 00:03:08,420 high-resolution data and a passive 63 00:03:13,390 --> 00:03:10,490 entrant instrument the radiometer which 64 00:03:16,210 --> 00:03:13,400 provides us high accuracy data these two 65 00:03:18,160 --> 00:03:16,220 interests instruments give us a picture 66 00:03:21,370 --> 00:03:18,170 similar to looking through both lenses 67 00:03:23,590 --> 00:03:21,380 of your bifocals at the same time so we 68 00:03:27,670 --> 00:03:23,600 end up with a very high accurate global 69 00:03:30,190 --> 00:03:27,680 map of the soil moisture content this 70 00:03:32,620 --> 00:03:30,200 dual vision activity was one of the 71 00:03:35,680 --> 00:03:32,630 reasons why the measurements that we're 72 00:03:37,990 --> 00:03:35,690 getting on snap was ranked so highly by 73 00:03:41,350 --> 00:03:38,000 the National Academies

final engine 217 00:10:20,039 --> 00:10:16,600 sloughs will be performed approximately 218 00:10:24,629 --> 00:10:20,049 5 25 a.m. pacific time and then we'll be 219 00:10:27,389 --> 00:10:24,639 ready for launch at 620 and 42 seconds 220 00:10:31,799 --> 00:10:27,399 a.m. pacific time with a three minute 221 00:10:33,869 --> 00:10:31,809 launch window in summary the delta 2 222 00:10:35,939 --> 00:10:33,879 rocket and SMAP spacecraft are ready and 223 00:10:37,919 --> 00:10:35,949 the launch team is prepared and excited 224 00:10:40,289 --> 00:10:37,929 to be here at Vandenberg Air Force Base 225 00:10:45,419 --> 00:10:40,299 to launch this important mission for our 226 00:10:47,909 --> 00:10:45,429 nation thank you Tim and now to Vern 227 00:10:49,939 --> 00:10:47,919 Thorpe he's the program manager for NASA 228 00:10:52,799 --> 00:10:49,949 missions for United Launch Alliance 229 00:10:55,289 --> 00:10:52,809 headquartered in Centennial Colorado run 230 00:10:58,199 --> 00:10:55,299 we'll discuss the ula roll with the 231 00:11:02,639 --> 00:10:58,209 Delta 2 and NASA and then the flight of 232 00:11:04,949 --> 00:11:02,649 the vehicle fern hey good afternoon the 233 00:11:07,290 --> 00:11:04,959 United Launch Alliance is honored to be 234 00:11:10,110 --> 00:11:07,300 here again two days before the launch of 235 00:11:12,060 --> 00:11:10,120 mapsatellite and I'm excited to be here 236 00:11:13,949 --> 00:11:12,070 for this first NASA launch of the year 237 00:11:16,949 --> 00:11:13,959 and also for the first of our ula 238 00:11:19,800 --> 00:11:16,959 launches during 2015 out of Vandenberg 239 00:11:22,290 --> 00:11:19,810 our ula team started working with NASA 240 00:11:23,790 --> 00:11:22,300 to integrate the SMAP spacecraft about 241 00:11:27,389 --> 00:11:23,800 two and a half years ago we started 242 00:11:29,220 --> 00:11:27,399 about July of 2014 we began building the 243 00:11:31,350 --> 00:11:29,230 vehicle for this particular mission in 244 00:11:34,470 --> 00:11:31,360 our factory in decatur alabama shortly 245 00:11:36,090 --> 00:11:34,480 after that and the entire time you la 246 00:11:38,970 --> 00:11:36,100 has worked very closely with the NASA 247 00:11:40,710 --> 00:11:38,980 launch services program the spacecraft 248 00:11:43,319 --> 00:11:40,720 team at the Jet Propulsion Laboratory 249 00:11:46,050 --> 00:11:43,329 and with our industry partners to get us 250 00:11:48,210 --> 00:11:46,060 to this day as always it's been a it's 251 00:11:49,380 --> 00:11:48,220 been a tremendous team effort and we 252 00:11:52,319 --> 00:11:49,390 look forward to a great launch on 253 00:11:55,710 --> 00:11:52,329 Thursday morning SMAP will actually be 254 00:11:57,509 --> 00:11:55,720 you la's second launch of 2015 following 255 00:11:59,670 --> 00:11:57,519 on the heels of our Atlas launch of the 256 00:12:03,750 --> 00:11:59,680 mules three spacecraft just one week ago 257 00:12:06,600 --> 00:12:03,760 today SMAP will also be the 150 third 258 00:12:10,560 --> 00:12:06,610 Delta two mission and it will be our 259 00:12:12,449 --> 00:12:10,570 52nd Delta two mission for NASA the SMAP 260 00:12:15,660 --> 00:12:12,459 mission will be launched aboard the 261 00:12:18,060 --> 00:12:15,670 Delta 273 20 configuration that includes 262 00:12:21,690 --> 00:12:18,070 a first-stage booster powered by the 263 00:12:23,360 --> 00:12:21,700 Aerojet Rocketdyne RS 27a engine and as 264 00:12:25,949 --> 00:12:23,370 Tim mentioned we'll have the three 265 00:12:29,430 --> 00:12:25,959 strapon solid rocket boosters provided 266 00:12:32,819 --> 00:12:29,440 by alliant techsystems or ATK the upper 267 00:12:36,480 --> 00:12:32,829 stage will be powered by the AJ ten 118k 268 00:12:38,639 --> 00:12:36,490 engine and the payload will be enclosed 269 00:12:40,319 --> 00:12:38,649 in that 10-foot diameter payload fairing 270 00:12:41,819 --> 00:12:40,329 that you saw that's a composite payload 271 00:12:43,740 --> 00:12:41,829 fairing we'll use that for the first few 272 00:12:46,050 --> 00:12:43,750 minutes of flight and jettison that once 273 00:12:47,910 --> 00:12:46,060 we're out of the atmosphere now I'd like 274 00:12:49,139 --> 00:12:47,920 to show you a video of the launch 275 00:12:50,400 --> 00:12:49,149 sequence and this will give you a 276 00:12:53,939 --> 00:12:50,410 preview of what we're going to see on 277 00:12:56,310 --> 00:12:53,949 thursday morning so here's the vehicle 278 00:12:59,970 --> 00:12:56,320 on the pad we're going to lift off 279 00:13:02,189 --> 00:12:59,980 shortly after 6 20 in the morning the 280 00:13:04,530 --> 00:13:02,199 window opens 43 seconds after that for 281 00:13:06,630 --> 00:13:04,540 three minutes as Tim said and the first 282 00:13:08,430 --> 00:13:06,640 major event you'll see after liftoff for 283 00:13:11,220 --> 00:13:08,440 this mission will happen when we 284 00:13:13,860 --> 00:13:11,230 jettison the SRBs 99 seconds into flight 285 00:13:15,420 --> 00:13:13,870 those SRBs actually burn out about a 286 00:13:17,569 --> 00:13:15,430 minute in the flight but we hang on to 287 00:13:19,800 --> 00:13:17,579 them until the predicted splashdown 288 00:13:20,420 --> 00:13:19,810 locations have cleared the the local 289 00:13:23,990 --> 00:13:20,430 offshore 290 00:13:27,019 --> 00:13:24,000 oil platforms so you'll see the SRBs 291 00:13:30,230 --> 00:13:27,029 jettison here in a moment once the SRBs 292 00:13:31,970 --> 00:13:30,240 of jettisoned the first stage will 293 00:13:39,230 --> 00:13:31,980 continue to fly for a total of about 294 00:13:40,820 --> 00:13:39,240 four minutes and 20 seconds and once 295 00:13:42,620 --> 00:13:40,830 we've used up the propellants in that 296 00:13:47,510 --> 00:13:42,630 first stage will shut down the engine 297 00:13:50,600 --> 00:13:47,520 and six seconds after that will separate 298 00:13:53,329 --> 00:13:50,610 the upper stage and eight seconds after 299 00:13:54,920 --> 00:13:53,339 that we will light the engine on that 300 00:13:58,579 --> 00:13:54,930 upper stage for the first as several 301 00:14:02,420 --> 00:13:58,589 burns for this mission now this first 302 00:14:05,750 --> 00:14:02,430 burn of the upper stage will last just a 303 00:14:07,370 --> 00:14:05,760 little bit more than six minutes shortly 304 00:14:13,370 --> 00:14:07,380 into that first stage burn will jettison 305 00:14:14,840 --> 00:14:13,380 the payload fairing as you see here and 306 00:14:16,490 --> 00:14:14,850 once we're done with that first burn 307 00:14:18,650 --> 00:14:16,500 will be in a parking orbit that parking 308 00:14:20,990 --> 00:14:18,660 orbit will last about 41 minutes and 309 00:14:22,970 --> 00:14:21,000 then we'll do a short second burn 310 00:14:25,010 --> 00:14:22,980 followed by spacecraft separation as you 311 00:14:27,500 --> 00:14:25,020 see right here spacecraft separation 312 00:14:30,680 --> 00:14:27,510 will occur about 57 minutes after 313 00:14:32,600 --> 00:14:30,690 liftoff for this mission now when we're 314 00:14:34,790 --> 00:14:32,610 done with the primary mission with 315 00:14:36,440 --> 00:14:34,800 separating the SMAP spacecraft we're 316 00:14:38,329 --> 00:14:36,450 actually going to do a third engine burn 317 00:14:41,230 --> 00:14:38,339 it'll be a very short burn about eight 318 00:14:43,730 --> 00:14:41,240 seconds to adjust the orbit slightly and 319 00:14:46,490 --> 00:14:43,740 following that we will actually be 320 00:14:48,860 --> 00:14:46,500 separating for cube sets we have three p 321 00:14:50,990 --> 00:14:48,870 pot dispensers on board that contain a 322 00:14:53,390 --> 00:14:51,000 total of four cube sets and then when 323 00:14:55,130 --> 00:14:53,400 we're done with the CubeSat separations 324 00:14:58,460 --> 00:14:55,140 will actually do a fourth engine burn 325 00:14:59,780 --> 00:14:58,470 and that fourth engine burn will burn 326 00:15:01,970 --> 00:14:59,790 all the propellants that are remaining 327 00:15:03,890 --> 00:15:01,980 in the second stage and that will allow 328 00:15:06,500 --> 00:15:03,900 us to actually do a controlled reentry 329 00:15:09,949 --> 00:15:06,510 of the second stage in about 2 hours and 330 00:15:11,600 --> 00:15:09,959 10 minutes after launch the second stage 331 00:15:14,210 --> 00:15:11,610 will splashdown in the Southern Pacific 332 00:15:17,750 --> 00:15:14,220 Ocean several hundred miles east of New 333 00:15:19,579 --> 00:15:17,760 Zealand so the men of women in ula are 334 00:15:21,650 --> 00:15:19,589 proud to serve a critical role in 335 00:15:22,990 --> 00:15:21,660 delivering payloads to orbit for all of 336 00:15:25,730 --> 00:15:23,000 our government and commercial customers 337 00:15:27,530 --> 00:15:25,740 it's our honor to launch this important 338 00:15:29,360 --> 00:15:27,540 earth science mission to help scientists 339 00:15:33,199 --> 00:15:29,370 better understand Earth's overall water 340 00:15:34,190 --> 00:15:33,209 energy and carbon cycles and ula always 341 00:15:35,990 --> 00:15:34,200 maintains a relentless 342 00:15:38,240 --> 00:15:36,000 focus on successfully delivering 343 00:15:39,920 --> 00:15:38,250 critical capabilities like this to orbit 344 00:15:42,470 --> 00:15:39,930 and we are very proud to be America's 345 00:15:44,330 --> 00:15:42,480 right to space so I'd like to say thank 346 00:15:47,450 --> 00:15:44,340 you again to all of our mission partners 347 00:15:49,070 --> 00:15:47,460 the entire ula team looks forward to a 348 00:15:50,570 --> 00:15:49,080 great launch on Thursday morning and 349 00:15:53,060 --> 00:15:50,580 with that I'll turn it back to you 350 00:15:55,520 --> 00:15:53,070 George Thank You Vern and now to 351 00:15:57,620 --> 00:15:55,530 continue with that threat of events and 352 00:16:00,500 --> 00:15:57,630 also talk some about this smash 353 00:16:02,240 --> 00:16:00,510 spacecraft is Kent Kellogg the SMAP 354 00:16:05,090 --> 00:16:02,250 project manager from the Jet Propulsion 355 00:16:07,460 --> 00:16:05,100 Laboratory in Pasadena California yeah 356 00:16:10,820 --> 00:16:07,470 thank you George and I want to add my 357 00:16:14,720 --> 00:16:10,830 thanks to NASA and the KSC launch 358 00:16:16,790 --> 00:16:14,730 services program team the SMAP project 359 00:16:19,580 --> 00:16:16,800 is absolutely thrilled to be catching a 360 00:16:23,420 --> 00:16:19,590 ride space on the Delta two vehicle 361 00:16:24,980 --> 00:16:23,430 vehicle with a very long and well proven 362 00:16:26,840 --> 00:16:24,990 history so we feel like we've been in 363 00:16:29,750 --> 00:16:26,850 very good hands and very well treated 364 00:16:32,240 --> 00:16:29,760 here at Vandenberg by the team's over 365 00:16:35,360 --> 00:16:32,250 the last few months I want to pick up 366 00:16:36,980 --> 00:16:35,370 where Verne left off by talking about 367 00:16:39,350 --> 00:16:36,990 what's going to happen with a spacecraft 368 00:16:41,270 --> 00:16:39,360 after we separate from the Delta two 369 00:16:45,200 --> 00:16:41,280 upper stage so if we could run that 370 00:16:48,980 --> 00:16:45,210 mission animation please so once we 371 00:16:52,070 --> 00:16:48,990 separate from the upper stage the upper 372 00:16:54,920 --> 00:16:52,080 stage will has a high-definition camera 373 00:16:58,310 --> 00:16:54,930 aboard that will stay focused on us for 374 00:17:00,370 --> 00:16:58,320 about 150 seconds after we separate we 375 00:17:03,560 --> 00:17:00,380 hope in that time to be able to catch 376 00:17:05,420 --> 00:17:03,570 the start of the solar array deployment 377 00:17:08,030 --> 00:17:05,430 on board sequences on the spacecraft 378 00:17:11,860 --> 00:17:08,040 will begin communicating back with the 379 00:17:15,800 --> 00:17:11,870 ground well deploy the solar arrays and 380 00:17:18,170 --> 00:17:15,810 will point the spacecraft and solar 381 00:17:21,230 --> 00:17:18,180 arrays toward the Sun we expect that 382 00:17:22,970 --> 00:17:21,240 process to be completed as early as 383 00:17:25,310 --> 00:17:22,980 eight minutes after we separate 384 00:17:27,890 --> 00:17:25,320 depending on the spacecraft attitude as 385 00:17:29,660 --> 00:17:27,900 we leave the Delta 2 or it could take as 386 00:17:31,730 --> 00:17:29,670 long as about 50 minutes so there's a 387 00:17:33,770 --> 00:17:31,740 little variation there we'll spend the 388 00:17:36,350 --> 00:17:33,780 first two weeks checking out the 389 00:17:39,110 --> 00:17:36,360 spacecraft system and then we will 390 00:17:41,570 --> 00:17:39,120 deploy our large instrument antenna that 391 00:17:43,340 --> 00:17:41,580 you see here on the screen will deploy 392 00:17:47,220 --> 00:17:43,350 the boom first and then four days later 393 00:17:49,799 --> 00:17:47,230 we'll deploy the large 20-foot reflector 394 00:17:52,740 --> 00:17:49,809 and then 50 days after launch we will 395 00:17:55,020 --> 00:17:52,750 spin up the reflector to have a fully 396 00:17:58,289 --> 00:17:55,030 operational observatory you'll notice 397 00:18:01,590 --> 00:17:58,299 the spacecraft counter rotates in the in 398 00:18:03,690 --> 00:18:01,600 the animation that's by design because 399 00:18:06,990 --> 00:18:03,700 of the large spinning mass that we are 400 00:18:09,450 --> 00:18:07,000 spinning up the antenna beam points off 401 00:18:11,760 --> 00:18:09,460 at an angle it doesn't point directly 402 00:18:14,310 --> 00:18:11,770 below the spacecraft and that allows us 403 00:18:17,850 --> 00:18:14,320 to map a large swath about a thousand 404 00:18:19,530 --> 00:18:17,860 kilometer wide swath below the 405 00:18:22,530 --> 00:18:19,540 spacecraft that allows us to map the 406 00:18:24,870 --> 00:18:22,540 entire globe in less than three days 407 00:18:28,490 --> 00:18:24,880 it's quite an efficient mapping system 408 00:18:33,240 --> 00:18:28,500 I've been working on this project for 409 00:18:35,460 --> 00:18:33,250 about six years now and a lot of design 410 00:18:37,770 --> 00:18:35,470 and effort has gone into it certainly 411 00:18:40,530 --> 00:18:37,780 some of the science folks working on the 412 00:18:43,620 --> 00:18:40,540 project have invested far more time in 413 00:18:46,200 --> 00:18:43,630 that 15 years and earlier and more in 414 00:18:48,570 --> 00:18:46,210 some cases a lot of effort has gone into 415 00:18:49,830 --> 00:18:48,580 this I want to share with you a little 416 00:18:54,180 --> 00:18:49,840 bit of the work if we could roll the 417 00:18:57,990 --> 00:18:54,190 hardware flow video we began assembling 418 00:19:01,200 --> 00:18:58,000 the spacecraft bus about a year and a 419 00:19:03,060 --> 00:19:01,210 half ago at JPL you can see here the 420 00:19:06,630 --> 00:19:03,070 solar arrays being deployed this is the 421 00:19:09,870 --> 00:19:06,640 radar panel being installed onto the 422 00:19:12,180 --> 00:19:09,880 spacecraft there's a lot of testing that 423 00:19:15,960 --> 00:19:12,190 goes into this this is a spin test of 424 00:19:18,169 --> 00:19:15,970 the radiometer and feed horn that was 425 00:19:22,070 --> 00:19:18,179 done before we installed it atop the 426 00:19:24,690 --> 00:19:22,080 spacecraft we go through vibration 427 00:19:27,270 --> 00:19:24,700 environments we test the large antenna 428 00:19:29,340 --> 00:19:27,280 that that obviously got a lot of 429 00:19:31,650 --> 00:19:29,350 attention to make sure we had well 430 00:19:36,180 --> 00:19:31,660 tested that to make sure we have a good 431 00:19:37,710 --> 00:19:36,190 system when we get into space we go 432 00:19:39,900 --> 00:19:37,720 through environmental testing to make 433 00:19:42,000 --> 00:19:39,910 sure that we're going to work as 434 00:19:44,039 --> 00:19:42,010 intended as we after we go through the 435 00:19:46,950 --> 00:19:44,049 vibration of the the launch environment 436 00:19:50,760 --> 00:19:46,960 and also in the vacuum environment and 437 00:19:54,120 --> 00:19:50,770 thermal environment in space so here you 438 00:19:57,149 --> 00:19:54,130 see some scenes of the spacecraft being 439 00:20:00,750 --> 00:19:57,159 put into our large 25-foot space 440 00:20:01,320 --> 00:20:00,760 simulator facility at JPL and then last 441 00:20:04,440 --> 00:20:01,330 July 442 00:20:09,170 --> 00:20:04,450 we did a final spin test of the spin 443 00:20:13,920 --> 00:20:09,180 platform on the observatory and then in 444 00:20:17,550 --> 00:20:13,930 October we shipped the observatory to 445 00:20:19,860 --> 00:20:17,560 Vandenberg so on October 15th we loaded 446 00:20:22,560 --> 00:20:19,870 the observatory into a truck and then 447 00:20:25,110 --> 00:20:22,570 early early that morning it arrived at 448 00:20:28,260 --> 00:20:25,120 Vandenberg at the Astra tech payload 449 00:20:31,470 --> 00:20:28,270 processing facility where we completed 450 00:20:34,110 --> 00:20:31,480 the last of the functional checkouts to 451 00:20:38,490 --> 00:20:34,120 make sure the observatory was operating 452 00:20:42,900 --> 00:20:38,500 properly after its transportation to 453 00:20:45,570 --> 00:20:42,910 Vandenberg we fueled the spacecraft went 454 00:20:49,440 --> 00:20:45,580 through the final checks everything went 455 00:20:52,530 --> 00:20:49,450 very smoothly we had no no issues or 456 00:20:55,980 --> 00:20:52,540 problems during that time and then as 457 00:21:00,000 --> 00:20:55,990 Tim described we begin the process of 458 00:21:03,870 --> 00:21:00,010 putting it inside it's a can to move out 459 00:21:07,110 --> 00:21:03,880 to space launch complex too so we've 460 00:21:10,530 --> 00:21:07,120 invested a lot of time testing testing 461 00:21:12,680 --> 00:21:10,540 the observatory we feel we've got a very 462 00:21:15,300 --> 00:21:12,690 reliable design we've got a very 463 00:21:17,520 --> 00:21:15,310 committed and passionate group of people 464 00:21:20,640 --> 00:21:17,530 that have worked on the project over 465 00:21:22,260 --> 00:21:20,650 many years we feel that we've got a lot 466 00:21:26,790 --> 00:21:22,270 of confidence that this mission is going 467 00:21:30,060 --> 00:21:26,800 to provide top quality science data for 468 00:21:32,370 --> 00:21:30,070 many many years in space I want to 469 00:21:35,670 --> 00:21:32,380 acknowledge that our mission partner 470 00:21:38,100 --> 00:21:35,680 here besides JPL who had project 471 00:21:39,840 --> 00:21:38,110 management responsibilities developed 472 00:21:42,120 --> 00:21:39,850 the spacecraft at the radar instrument 473 00:21:44,160 --> 00:21:42,130 we also had a lot of support from the 474 00:21:47,430 --> 00:21:44,170 NASA's Goddard Space Flight assembly 475 00:21:51,540 --> 00:21:47,440 that provided the radiometer instrument 476 00:21:55,020 --> 00:21:51,550 science support both centers share in 477 00:22:00,240 --> 00:21:55,030 the science data processing that will be 478 00:22:05,370 --> 00:22:00,250 performed once we get the data flowing 479 00:22:08,640 --> 00:22:05,380 from space so with that I think we still 480 00:22:11,660 --> 00:22:08,650 are showing some video here this is of 481 00:22:13,940 --> 00:22:11,670 the spacecraft being attached to its 482 00:22:16,580 --> 00:22:13,950 launch vehicle adapter 483 00:22:23,590 --> 00:22:16,590 at Astro tech before it was put inside 484 00:22:26,360 --> 00:22:23,600 the can it was moved to slick to on 485 00:22:29,930 --> 00:22:26,370 January thirteenth so we've had a very 486 00:22:31,759 --> 00:22:29,940 smooth operation getting it installed on 487 00:22:36,110 --> 00:22:31,769 the launch vehicle adapter you see here 488 00:22:43,190 --> 00:22:36,120 and getting it transported out to out 489 00:22:46,310 --> 00:22:43,200 too slick to so with that George well 490 00:22:48,500 --> 00:22:46,320 the video winds up I'll turn it back to 491 00:22:51,169 --> 00:22:48,510 you thank you all right Thank You cat 492 00:22:53,840 --> 00:22:51,179 and now to learn more about this map 493 00:22:55,279 --> 00:22:53,850 mission Dhara anto kabhi the SMAP 494 00:22:57,470 --> 00:22:55,289 science team leader from the 495 00:23:00,230 --> 00:22:57,480 massachusetts institute of technology in 496 00:23:03,190 --> 00:23:00,240 cambridge massachusetts tara thank 497 00:23:07,909 --> 00:23:03,200 George smot is in a unique position 498 00:23:10,879 --> 00:23:07,919 because its measurements impact two 499 00:23:13,549 --> 00:23:10,889 distinct domains one of course as a 500 00:23:15,470 --> 00:23:13,559 science mission it impacts how we 501 00:23:17,539 --> 00:23:15,480 fundamentally understand how the 502 00:23:20,539 --> 00:23:17,549 environment works and peer into the 503 00:23:23,600 --> 00:23:20,549 metabolism of the environment and second 504 00:23:25,279 --> 00:23:23,610 it impacts some of the applications that 505 00:23:27,379 --> 00:23:25,289 touch our of their lives I would like to 506 00:23:31,360 --> 00:23:27,389 give you examples of each one of those 507 00:23:35,450 --> 00:23:31,370 and to the first slide in the area of 508 00:23:38,389 --> 00:23:35,460 science impacts as a science mission the 509 00:23:40,279 --> 00:23:38,399 three cycles that maintain life on Earth 510 00:23:42,740 --> 00:23:40,289 are our fundamental cycles of the earth 511 00:23:47,779 --> 00:23:42,750 system the water cycle unique to earth 512 00:23:49,700 --> 00:23:47,789 the energy cycle and the carbon cycle d3 513 00:23:51,169 --> 00:23:49,710 are linked together through soil 514 00:23:53,930 --> 00:23:51,179 moisture and free stock they're like 515 00:23:56,870 --> 00:23:53,940 three gears in a clock if one of them 516 00:24:00,200 --> 00:23:56,880 speeds up it affects the others and as a 517 00:24:02,090 --> 00:24:00,210 cascading downstream effect if it wasn't 518 00:24:04,820 --> 00:24:02,100 for soil moisture these three gears 519 00:24:07,310 --> 00:24:04,830 would act independently and would vary 520 00:24:09,409 --> 00:24:07,320 without any synchronization but we know 521 00:24:12,470 --> 00:24:09,419 that's not the case as soil water 522 00:24:14,000 --> 00:24:12,480 evaporates that's precipitation that has 523 00:24:16,639 --> 00:24:14,010 gone into the soil so it's the history 524 00:24:19,009 --> 00:24:16,649 of precipitation as that evaporates it 525 00:24:20,899 --> 00:24:19,019 feeds the clouds and returns that 526 00:24:23,869 --> 00:24:20,909 precipitation back to the atmosphere and 527 00:24:26,720 --> 00:24:23,879 you got a water cycle going just as 528 00:24:27,919 --> 00:24:26,730 humans have adapted to perspire in order 529 00:24:30,019 --> 00:24:27,929 to maintain their body temp 530 00:24:32,810 --> 00:24:30,029 the earth does the same it takes energy 531 00:24:36,409 --> 00:24:32,820 to vaporize that water so it's involved 532 00:24:38,060 --> 00:24:36,419 in the energy cycle the solar radiation 533 00:24:40,460 --> 00:24:38,070 that's incidents that the surface gets 534 00:24:42,350 --> 00:24:40,470 absorbed and gets released back or 535 00:24:43,940 --> 00:24:42,360 dissipated through the evaporation 536 00:24:46,389 --> 00:24:43,950 process so that's how the water and 537 00:24:51,169 --> 00:24:46,399 energy cycles are intimately linked and 538 00:24:53,539 --> 00:24:51,179 also plants as they transpire what they 539 00:24:55,940 --> 00:24:53,549 do is take carbon dioxide gas from the 540 00:24:58,039 --> 00:24:55,950 atmosphere take energy from sunlight and 541 00:25:00,169 --> 00:24:58,049 convert that into the leaves and 542 00:25:03,049 --> 00:25:00,179 branches that they have by releasing 543 00:25:05,149 --> 00:25:03,059 water vapor so the carbon cycle gets 544 00:25:07,759 --> 00:25:05,159 engaged with the water and energy cycles 545 00:25:09,529 --> 00:25:07,769 these three work again like gears in a 546 00:25:11,659 --> 00:25:09,539 clock and have to be synchronized our 547 00:25:13,669 --> 00:25:11,669 models of the environment whether they 548 00:25:17,450 --> 00:25:13,679 used for short-term numerical weather 549 00:25:19,930 --> 00:25:17,460 prediction or longer-term projections of 550 00:25:22,700 --> 00:25:19,940 the impacts of climate variability and 551 00:25:25,340 --> 00:25:22,710 climate change on regional water cycle 552 00:25:27,019 --> 00:25:25,350 need to get this coupling between the 553 00:25:29,359 --> 00:25:27,029 three cycles correctly and therefore 554 00:25:32,330 --> 00:25:29,369 need the store moisture information that 555 00:25:34,700 --> 00:25:32,340 map is going to provide so that's the 556 00:25:37,519 --> 00:25:34,710 science impact of peering into how the 557 00:25:40,549 --> 00:25:37,529 earth environments metabolism functions 558 00:25:42,889 --> 00:25:40,559 in the area of applications by go to the 559 00:25:45,919 --> 00:25:42,899 next slide here's an example that 560 00:25:47,749 --> 00:25:45,929 touches are over their lives this is 561 00:25:50,149 --> 00:25:47,759 from the National Weather Service from 562 00:25:52,970 --> 00:25:50,159 their website this is their flash flood 563 00:25:55,249 --> 00:25:52,980 guidance it's produced daily and the 564 00:25:57,320 --> 00:25:55,259 date on the top indicates what day that 565 00:25:59,749 --> 00:25:57,330 was the validity of this particular map 566 00:26:02,869 --> 00:25:59,759 and it's basically so much your deficit 567 00:26:05,299 --> 00:26:02,879 how much the soil can hold beyond what 568 00:26:07,850 --> 00:26:05,309 the current so moisture conditions are 569 00:26:10,730 --> 00:26:07,860 and it's in units of inches this is 570 00:26:13,070 --> 00:26:10,740 produced daily updated daily and shipped 571 00:26:15,379 --> 00:26:13,080 out to about 120 weather forecast 572 00:26:19,460 --> 00:26:15,389 offices spread around the country the 573 00:26:21,680 --> 00:26:19,470 forecaster looks at this map looks at 574 00:26:24,200 --> 00:26:21,690 the NEXRAD radar ground-based radar 575 00:26:26,330 --> 00:26:24,210 precipitation map also in units of 576 00:26:28,220 --> 00:26:26,340 inches of precipitation and whatever the 577 00:26:31,340 --> 00:26:28,230 precipitation exceeds the flight 578 00:26:34,399 --> 00:26:31,350 guidance immediately a flood warning is 579 00:26:36,889 --> 00:26:34,409 issued now this map of surface soil 580 00:26:39,909 --> 00:26:36,899 moisture or soil moisture deficit is not 581 00:26:41,360 --> 00:26:39,919 produced based upon ground-based 582 00:26:42,650 --> 00:26:41,370 instruments 583 00:26:46,690 --> 00:26:42,660 that measures one measure around the 584 00:26:49,400 --> 00:26:46,700 country because there's far too few as 585 00:26:51,920 --> 00:26:49,410 ground-based sensors to come close to 586 00:26:55,130 --> 00:26:51,930 producing such a map so this is produced 587 00:26:57,170 --> 00:26:55,140 by models best guesses of what the soil 588 00:27:00,730 --> 00:26:57,180 moisture congestion should be any one 589 00:27:03,710 --> 00:27:00,740 day now what's map will provide is 590 00:27:07,070 --> 00:27:03,720 exactly that measurement but at higher 591 00:27:09,049 --> 00:27:07,080 resolution and directly and with great 592 00:27:12,590 --> 00:27:09,059 accuracy so it's going to help improve 593 00:27:15,200 --> 00:27:12,600 this daily operation that goes on in a 594 00:27:18,650 --> 00:27:15,210 second example and the final example 595 00:27:21,260 --> 00:27:18,660 here's a daughter extreme this is a 596 00:27:23,990 --> 00:27:21,270 weekly map produced by a collaboration 597 00:27:26,660 --> 00:27:24,000 between US Department of Agriculture EPA 598 00:27:30,080 --> 00:27:26,670 and so noah and some other agencies and 599 00:27:32,660 --> 00:27:30,090 its validity of this one is just a few 600 00:27:36,880 --> 00:27:32,670 days ago and this is an estimate of 601 00:27:39,380 --> 00:27:36,890 drought conditions this drought is 602 00:27:41,930 --> 00:27:39,390 agricultural drought is defined in terms 603 00:27:44,120 --> 00:27:41,940 of deficit in soil moisture so the very 604 00:27:45,980 --> 00:27:44,130 definition of drought is a deficit in 605 00:27:48,740 --> 00:27:45,990 soil moisture and you can see the big 606 00:27:51,110 --> 00:27:48,750 dry in California on this map again 607 00:27:53,240 --> 00:27:51,120 what's map can provide is a direct 608 00:27:56,410 --> 00:27:53,250 measurement of this quantity at high 609 00:28:00,950 --> 00:27:56,420 resolution and from space and globally 610 00:28:02,690 --> 00:28:00,960 so with that George Thank You Dora and 611 00:28:05,120 --> 00:28:02,700 we'll look now at the weather forecast 612 00:28:06,740 --> 00:28:05,130 for Thursday morning from First 613 00:28:08,660 --> 00:28:06,750 Lieutenant John Martin they launch 614 00:28:11,060 --> 00:28:08,670 weather officer for the countdown on 615 00:28:13,970 --> 00:28:11,070 Thursday from the 30th operation support 616 00:28:16,010 --> 00:28:13,980 quadrant at Vandenberg thank you George 617 00:28:18,049 --> 00:28:16,020 weather along the central California 618 00:28:20,000 --> 00:28:18,059 coast and January typically consist of 619 00:28:21,919 --> 00:28:20,010 shallow high pressure with occasional 620 00:28:24,169 --> 00:28:21,929 low pressure systems that transition 621 00:28:25,549 --> 00:28:24,179 through the region currently California 622 00:28:27,110 --> 00:28:25,559 is seeing some of the shallow high 623 00:28:29,390 --> 00:28:27,120 pressure building into the region with 624 00:28:31,910 --> 00:28:29,400 upper area upper level areas of low 625 00:28:33,799 --> 00:28:31,920 pressure skirting into over the high and 626 00:28:36,020 --> 00:28:33,809 causing increased cloud cover in the mid 627 00:28:38,600 --> 00:28:36,030 to upper levels if we could take a look 628 00:28:40,310 --> 00:28:38,610 at the satellite coverage here you can 629 00:28:41,750 --> 00:28:40,320 see clear skies over most of the range 630 00:28:43,760 --> 00:28:41,760 with the lingering upper level low 631 00:28:45,200 --> 00:28:43,770 causing increased cloud cover along the 632 00:28:47,660 --> 00:28:45,210 northern portion of the western range 633 00:28:49,370 --> 00:28:47,670 the upper level feature is tracking to 634 00:28:51,830 --> 00:28:49,380 the north east and is not expected to be 635 00:28:53,360 --> 00:28:51,840 an impact for Thursday's launch if we 636 00:28:54,409 --> 00:28:53,370 could move on to the launch forecast 637 00:28:57,139 --> 00:28:54,419 slide 638 00:28:59,269 --> 00:28:57,149 alright so for Thursday we are expecting 639 00:29:00,919 --> 00:28:59,279 another slight upper level low pressure 640 00:29:02,899 --> 00:29:00,929 system that will move over the region 641 00:29:05,029 --> 00:29:02,909 late Wednesday and into early Thursday 642 00:29:06,889 --> 00:29:05,039 morning bringing thicker mid-level to 643 00:29:08,690 --> 00:29:06,899 upper level clouds with a little bit of 644 00:29:10,070 --> 00:29:08,700 Cirrus over the range forty zero 645 00:29:12,019 --> 00:29:10,080 visibility will be under strict 646 00:29:15,109 --> 00:29:12,029 unrestricted with winds out of the north 647 00:29:16,970 --> 00:29:15,119 northeast between eight to 12 knots at 648 00:29:18,979 --> 00:29:16,980 slick two temperatures will be 649 00:29:21,139 --> 00:29:18,989 comfortably in the low to mid 50s the 650 00:29:23,060 --> 00:29:21,149 overall probability of violation for t0 651 00:29:25,039 --> 00:29:23,070 is twenty percent with the only 652 00:29:27,200 --> 00:29:25,049 constraint of concern being for thick 653 00:29:29,930 --> 00:29:27,210 clouds if we could shift to the scrub 654 00:29:31,460 --> 00:29:29,940 forecast line lingering moisture from 655 00:29:34,070 --> 00:29:31,470 that upper level low will move east of 656 00:29:35,869 --> 00:29:34,080 the range for Friday resulting in 657 00:29:37,609 --> 00:29:35,879 thinning clouds aloft and the thick 658 00:29:40,070 --> 00:29:37,619 cloud probability of violation dropping 659 00:29:42,109 --> 00:29:40,080 20 percent for the scrub day winds will 660 00:29:45,049 --> 00:29:42,119 shift to a northwesterly component pick 661 00:29:46,909 --> 00:29:45,059 up to around 15 to 18 knots at slick to 662 00:29:48,889 --> 00:29:46,919 with visibility still remaining 663 00:29:50,419 --> 00:29:48,899 unrestricted and temperatures will start 664 00:29:52,609 --> 00:29:50,429 to climb a little bit to the mid to 665 00:29:54,259 --> 00:29:52,619 upper 50s overall probability of 666 00:29:55,700 --> 00:29:54,269 violation for the scrub day will be ten 667 00:29:57,619 --> 00:29:55,710 percent with the only constraint of 668 00:29:59,779 --> 00:29:57,629 concern being the surface winds that 669 00:30:01,609 --> 00:29:59,789 slick too and that is all for weather 670 00:30:03,529 --> 00:30:01,619 back to you George all right thank you 671 00:30:06,320 --> 00:30:03,539 very much lieutenant Martin and we're 672 00:30:09,379 --> 00:30:06,330 ready now to take questions for the 673 00:30:13,070 --> 00:30:09,389 social media you can use hashtag ask 674 00:30:15,080 --> 00:30:13,080 NASA and we will go right now to some 675 00:30:16,669 --> 00:30:15,090 questions here in the room and take some 676 00:30:18,229 --> 00:30:16,679 social media questions so we'll start 677 00:30:20,210 --> 00:30:18,239 here in the front and please give your 678 00:30:23,419 --> 00:30:20,220 name and affiliation when you get the 679 00:30:26,149 --> 00:30:23,429 microphone Justin Justin ray with the 680 00:30:27,440 --> 00:30:26,159 spaceflight now calm for Kent I was 681 00:30:29,810 --> 00:30:27,450 wondering if you could explain a little 682 00:30:34,369 --> 00:30:29,820 bit more about how they antenna is 683 00:30:38,590 --> 00:30:34,379 deployed what actually drives it out ok 684 00:30:42,680 --> 00:30:38,600 so the antenna as a motor actuator that 685 00:30:46,070 --> 00:30:42,690 drives a drives the system it basically 686 00:30:50,330 --> 00:30:46,080 unfolds like a like a like a rhombus if 687 00:30:53,539 --> 00:30:50,340 you will that moves from a you know 688 00:30:56,060 --> 00:30:53,549 collapsed state into a deployed state so 689 00:30:58,399 --> 00:30:56,070 it is initially blooms out you saw in 690 00:31:00,470 --> 00:30:58,409 the animation right after it releases it 691 00:31:02,810 --> 00:31:00,480 blooms out to about 78 feet in diameter 692 00:31:06,470 --> 00:31:02,820 and then there's a cable drive system 693 00:31:07,520 --> 00:31:06,480 that powers it out to the remaining 20 694 00:31:09,980 --> 00:31:07,530 feet in diameter 695 00:31:12,470 --> 00:31:09,990 that process takes about 30 minutes in 696 00:31:14,630 --> 00:31:12,480 space so we were able to show it the 697 00:31:17,870 --> 00:31:14,640 animation running much more rapidly than 698 00:31:20,780 --> 00:31:17,880 it would in real time when we deploy it 699 00:31:23,120 --> 00:31:20,790 we would have full telemetry visibility 700 00:31:25,670 --> 00:31:23,130 via t dress we've designed that process 701 00:31:29,080 --> 00:31:25,680 very carefully so we can we can watch it 702 00:31:32,000 --> 00:31:29,090 but the deployment is dealt with 703 00:31:34,910 --> 00:31:32,010 autonomously by the by the spacecraft 704 00:31:36,560 --> 00:31:34,920 while it's while it's happening so did I 705 00:31:38,540 --> 00:31:36,570 answer your questions yep and just a 706 00:31:40,070 --> 00:31:38,550 quick follow-up when do you actually 707 00:31:44,690 --> 00:31:40,080 expect the spacecraft to become 708 00:31:47,750 --> 00:31:44,700 operational so operational is maybe 709 00:31:51,980 --> 00:31:47,760 that's a bit of ambiguous it can be an 710 00:31:54,110 --> 00:31:51,990 ambiguous term the we will spend 90 days 711 00:31:56,900 --> 00:31:54,120 checking out the spacecraft system 712 00:31:59,020 --> 00:31:56,910 deploying the antenna spinning it up 713 00:32:01,820 --> 00:31:59,030 getting the instrument fully checked out 714 00:32:05,210 --> 00:32:01,830 making sure all the systems are working 715 00:32:08,660 --> 00:32:05,220 properly we've allowed 90 days for that 716 00:32:10,700 --> 00:32:08,670 to occur after the 90-day period we will 717 00:32:12,860 --> 00:32:10,710 go into what's called a calibration and 718 00:32:14,930 --> 00:32:12,870 validation phase that's where we're 719 00:32:18,410 --> 00:32:14,940 actively using the instrument to collect 720 00:32:22,040 --> 00:32:18,420 data on soil moisture and then we have a 721 00:32:23,540 --> 00:32:22,050 science calibration validation team that 722 00:32:26,060 --> 00:32:23,550 takes the data coming from the 723 00:32:28,190 --> 00:32:26,070 spacecraft and compares it the ground 724 00:32:30,790 --> 00:32:28,200 truth sensors so we can bring the 725 00:32:33,950 --> 00:32:30,800 spacecraft data into alignment with 726 00:32:35,450 --> 00:32:33,960 specific sites around the globe to make 727 00:32:40,070 --> 00:32:35,460 sure that we're meeting our data 728 00:32:42,290 --> 00:32:40,080 accuracy requirements that that soil 729 00:32:46,100 --> 00:32:42,300 moisture data will be basically 730 00:32:49,400 --> 00:32:46,110 available not fully calibrated six 731 00:32:51,020 --> 00:32:49,410 months well six months after we complete 732 00:32:54,740 --> 00:32:51,030 the checkout period nine months after 733 00:32:57,170 --> 00:32:54,750 launch the validated science data 734 00:33:00,170 --> 00:32:57,180 calibrated soil moisture science data 735 00:33:03,500 --> 00:33:00,180 will be available 12 months after the 736 00:33:08,060 --> 00:33:03,510 checkout period is is complete 15 months 737 00:33:10,280 --> 00:33:08,070 after launch Janine Janine Scully 738 00:33:12,110 --> 00:33:10,290 Noozhawk calm you talked about working 739 00:33:14,720 --> 00:33:12,120 on this program for quite a few years 740 00:33:17,150 --> 00:33:14,730 how eager are you to finally get to this 741 00:33:21,170 --> 00:33:17,160 day and basically get to Thursday and 742 00:33:21,170 --> 00:33:21,180 get this get this process going 743 00:33:29,000 --> 00:33:25,520 I'm extremely eager my wife is probably 744 00:33:32,690 --> 00:33:29,010 even more extremely eager you know I you 745 00:33:34,610 --> 00:33:32,700 you you you work a lot of time to spend 746 00:33:36,950 --> 00:33:34,620 a lot of time to reach this point you 747 00:33:39,560 --> 00:33:36,960 know you invest a lot long hours 748 00:33:41,660 --> 00:33:39,570 weekends you know everyone that works on 749 00:33:43,370 --> 00:33:41,670 these kind of projects is very 750 00:33:47,570 --> 00:33:43,380 passionate they they invest a lot of 751 00:33:49,730 --> 00:33:47,580 themselves in it and it's great to reach 752 00:33:50,930 --> 00:33:49,740 this point it's also a point where 753 00:33:52,730 --> 00:33:50,940 you're putting all the marbles on the 754 00:33:54,830 --> 00:33:52,740 table this is the point where you know 755 00:33:56,390 --> 00:33:54,840 you're it's like adding over the keys to 756 00:33:59,960 --> 00:33:56,400 your car to your teenager you know you 757 00:34:03,680 --> 00:33:59,970 you hope you've prepared them well you 758 00:34:06,710 --> 00:34:03,690 hope all the lessons stick and and then 759 00:34:09,620 --> 00:34:06,720 you send them off and most of the time 760 00:34:12,530 --> 00:34:09,630 you're very pleasantly surprised but 761 00:34:14,710 --> 00:34:12,540 yeah we're very excited and we think 762 00:34:17,600 --> 00:34:14,720 we're going to have a great mission here 763 00:34:19,730 --> 00:34:17,610 and for those of us that are writing for 764 00:34:21,770 --> 00:34:19,740 the more general population can you help 765 00:34:25,010 --> 00:34:21,780 us explain exactly why Joe citizen 766 00:34:28,940 --> 00:34:25,020 should really care about this this 767 00:34:33,050 --> 00:34:28,950 mission I think Dara your why don't you 768 00:34:35,960 --> 00:34:33,060 answer that yeah so what the so much 769 00:34:38,330 --> 00:34:35,970 measurements will do is improve our 770 00:34:40,900 --> 00:34:38,340 weather forecasts improve our 771 00:34:45,530 --> 00:34:40,910 assessments or water availability and 772 00:34:47,680 --> 00:34:45,540 also address some issues dealing with 773 00:34:51,530 --> 00:34:47,690 long-term climate variability and 774 00:34:52,880 --> 00:34:51,540 assessments of the impact of human 775 00:34:56,720 --> 00:34:52,890 intervention in the global environment 776 00:34:58,790 --> 00:34:56,730 so all of these come together and it's 777 00:35:01,010 --> 00:34:58,800 the metabolism of the system how it 778 00:35:03,740 --> 00:35:01,020 responds just like a human body if you 779 00:35:06,470 --> 00:35:03,750 perturb it by feeding it something we 780 00:35:08,780 --> 00:35:06,480 want to know how it the entire 781 00:35:10,820 --> 00:35:08,790 metabolism working together response and 782 00:35:12,980 --> 00:35:10,830 that's the water engine carbon cycles 783 00:35:16,430 --> 00:35:12,990 this is the variable that links all of 784 00:35:19,220 --> 00:35:16,440 them so whether its water availability 785 00:35:22,190 --> 00:35:19,230 weather forecast climate seasonal 786 00:35:24,250 --> 00:35:22,200 climate forecast agriculture early 787 00:35:29,600 --> 00:35:24,260 famine warning all these applications 788 00:35:31,670 --> 00:35:29,610 really depend on this key valuable right 789 00:35:35,239 --> 00:35:31,680 any other questions here in the room we 790 00:35:39,809 --> 00:35:38,039 hi Patrick Healy from NBC 4 in Los 791 00:35:41,460 --> 00:35:39,819 Angeles and dr. inta copy if I could 792 00:35:43,859 --> 00:35:41,470 follow up on that and ask you to be 793 00:35:45,299 --> 00:35:43,869 perhaps a little more granular are we 794 00:35:46,799 --> 00:35:45,309 talking about in the case of flood 795 00:35:49,079 --> 00:35:46,809 prevention actually being able to go to 796 00:35:50,940 --> 00:35:49,089 a region and telling people you should 797 00:35:53,009 --> 00:35:50,950 leave this area because the probability 798 00:35:54,839 --> 00:35:53,019 of flooding is very high and conversely 799 00:35:57,289 --> 00:35:54,849 in California where we're dealing with 800 00:36:00,299 --> 00:35:57,299 this drought up are there specific 801 00:36:02,940 --> 00:36:00,309 decision making data that will become 802 00:36:04,859 --> 00:36:02,950 available and that could be utilized so 803 00:36:07,920 --> 00:36:04,869 let me go back to the first one the 804 00:36:09,749 --> 00:36:07,930 flood case as you saw that was a map of 805 00:36:11,970 --> 00:36:09,759 daily Sun worship without by the 806 00:36:15,390 --> 00:36:11,980 National Weather Service so if you have 807 00:36:18,269 --> 00:36:15,400 real data to test that operational 808 00:36:22,140 --> 00:36:18,279 product and that application you will 809 00:36:26,099 --> 00:36:22,150 impact the entire operation of flood 810 00:36:28,229 --> 00:36:26,109 forecasting in the country and also that 811 00:36:29,640 --> 00:36:28,239 applies internationally as well which is 812 00:36:32,279 --> 00:36:29,650 important because it's a satellite 813 00:36:34,650 --> 00:36:32,289 measurements in terms of drought the 814 00:36:36,960 --> 00:36:34,660 very definition of drought when you say 815 00:36:39,390 --> 00:36:36,970 this county is in drought condition this 816 00:36:42,509 --> 00:36:39,400 one's not is based upon what the soil 817 00:36:45,029 --> 00:36:42,519 moisture is right now we're making that 818 00:36:46,680 --> 00:36:45,039 decision based upon models this would be 819 00:36:49,910 --> 00:36:46,690 a direct measurement of that quantity 820 00:36:53,150 --> 00:36:49,920 that it could affect things like 821 00:36:56,160 --> 00:36:53,160 agricultural operations insurance 822 00:37:02,339 --> 00:36:56,170 disaster relief emergency declarations 823 00:37:05,249 --> 00:37:02,349 and other activities alright I think 824 00:37:07,829 --> 00:37:05,259 we're ready now to take social media 825 00:37:11,789 --> 00:37:07,839 questions and if you do in social media 826 00:37:14,900 --> 00:37:11,799 have a question you can use the hashtag 827 00:37:17,160 --> 00:37:14,910 ask NASA to send your question to us and 828 00:37:20,460 --> 00:37:17,170 have we got questions that have come in 829 00:37:23,279 --> 00:37:20,470 already indeed twitter user Kevin asks 830 00:37:24,120 --> 00:37:23,289 how long will nasus map be in space so 831 00:37:31,680 --> 00:37:24,130 if you want to talk about the mission 832 00:37:33,660 --> 00:37:31,690 duration so I'll take that so we have an 833 00:37:38,309 --> 00:37:33,670 operator we have a requirement to 834 00:37:42,690 --> 00:37:38,319 operates map for three years that's more 835 00:37:45,240 --> 00:37:42,700 of a funding of planning constraint if 836 00:37:49,320 --> 00:37:45,250 the spacecraft is returning healthy 837 00:37:52,020 --> 00:37:49,330 the data and as useful nASA has the 838 00:37:55,260 --> 00:37:52,030 option to extend the mission typically 839 00:37:58,170 --> 00:37:55,270 these missions you know can last for a 840 00:37:59,670 --> 00:37:58,180 decade or more and we expect if the 841 00:38:02,400 --> 00:37:59,680 spacecraft is healthy it should be 842 00:38:04,800 --> 00:38:02,410 capable of that nASA has a process that 843 00:38:06,630 --> 00:38:04,810 they go through once we've reached the 844 00:38:08,520 --> 00:38:06,640 end of our primary life that three-year 845 00:38:11,340 --> 00:38:08,530 period where they're well where they 846 00:38:13,080 --> 00:38:11,350 will evaluate whether they want to 847 00:38:16,410 --> 00:38:13,090 allocate additional funding to extend 848 00:38:17,730 --> 00:38:16,420 the mission so that's we expect the 849 00:38:20,190 --> 00:38:17,740 spacecraft itself though and the 850 00:38:24,360 --> 00:38:20,200 instrument to be healthy and last for 851 00:38:26,220 --> 00:38:24,370 many many many years wonderful this next 852 00:38:28,050 --> 00:38:26,230 question comes from amber who asks can 853 00:38:30,090 --> 00:38:28,060 you explain the use of stages in 854 00:38:31,530 --> 00:38:30,100 deploying the cube SATs so you can 855 00:38:38,220 --> 00:38:31,540 explain the deployment process for that 856 00:38:40,620 --> 00:38:38,230 a little bit I can give it a try yeah so 857 00:38:45,660 --> 00:38:40,630 for the cube sets we use what are called 858 00:38:47,970 --> 00:38:45,670 pea pods and essentially it's a box 859 00:38:49,170 --> 00:38:47,980 about the size of a loaf of bread a 860 00:38:55,160 --> 00:38:49,180 little bit bigger and it has a door on 861 00:38:58,020 --> 00:38:55,170 one end and inside you can have a small 862 00:38:59,340 --> 00:38:58,030 cube that hence the name cube SATs you 863 00:39:02,220 --> 00:38:59,350 can have one two or three of those 864 00:39:04,560 --> 00:39:02,230 inside and when it comes time to deploy 865 00:39:06,780 --> 00:39:04,570 those we simply send a command that 866 00:39:08,820 --> 00:39:06,790 allows a spring-loaded door to pop open 867 00:39:10,650 --> 00:39:08,830 on one end of that box and there's a 868 00:39:14,280 --> 00:39:10,660 spring deployment mechanism that just 869 00:39:15,960 --> 00:39:14,290 pushes the satellites out so we do have 870 00:39:17,640 --> 00:39:15,970 a briefing immediately following this 871 00:39:19,500 --> 00:39:17,650 one on the cube set so we'll go in a 872 00:39:22,770 --> 00:39:19,510 little bit more bead detail and help how 873 00:39:24,030 --> 00:39:22,780 that's going to work wonderful an 874 00:39:26,130 --> 00:39:24,040 additional question here comes from 875 00:39:28,080 --> 00:39:26,140 twitter user harris who asks how does a 876 00:39:30,360 --> 00:39:28,090 satellite that high in space accurately 877 00:39:35,640 --> 00:39:30,370 measure moisture in the soil underground 878 00:39:38,370 --> 00:39:35,650 on earth that's the that's the beauty of 879 00:39:40,890 --> 00:39:38,380 the microwave range is that you can see 880 00:39:45,420 --> 00:39:40,900 through clouds you can see regardless of 881 00:39:48,720 --> 00:39:45,430 daylight or no sunlight see through 882 00:39:51,120 --> 00:39:48,730 vegetation moderate vegetation and the 883 00:39:55,740 --> 00:39:51,130 signal is sensitive to the amount of 884 00:39:58,080 --> 00:39:55,750 moisture in the ground and the the 885 00:40:00,090 --> 00:39:58,090 radiometer acts like a camera it 886 00:40:02,220 --> 00:40:00,100 catcher catches the ambient amount of 887 00:40:04,110 --> 00:40:02,230 radiation being emitted but it's 888 00:40:07,830 --> 00:40:04,120 resolution is limited by the size of the 889 00:40:09,600 --> 00:40:07,840 antenna the radar acts like a flash 890 00:40:11,790 --> 00:40:09,610 camera it actually emits a pulse of 891 00:40:14,160 --> 00:40:11,800 radiation looks at what comes back it 892 00:40:16,440 --> 00:40:14,170 has the advantage of resolution the 893 00:40:18,810 --> 00:40:16,450 combination of these two is what makes 894 00:40:22,350 --> 00:40:18,820 the soil moisture measurements possible 895 00:40:25,650 --> 00:40:22,360 now the the pairing of these two 896 00:40:28,110 --> 00:40:25,660 instruments and the way they're operated 897 00:40:29,400 --> 00:40:28,120 are optimized for the problem of soil 898 00:40:34,800 --> 00:40:29,410 moisture and that's what's unique about 899 00:40:36,420 --> 00:40:34,810 the mission alright another question 900 00:40:38,310 --> 00:40:36,430 here from Twitter user amber who asks 901 00:40:40,080 --> 00:40:38,320 how long before SMAP data will be made 902 00:40:45,170 --> 00:40:40,090 available and will there be a certain 903 00:40:50,190 --> 00:40:48,270 I will I will answer the first part of 904 00:40:52,680 --> 00:40:50,200 that NASA actually chose to put the snap 905 00:40:54,960 --> 00:40:52,690 data into two different Dax one for the 906 00:40:59,850 --> 00:40:54,970 radar and one for the radiometer the 907 00:41:02,490 --> 00:40:59,860 national ice centre in Boulder and the 908 00:41:05,280 --> 00:41:02,500 Alaskan satellite facility up in 909 00:41:09,060 --> 00:41:05,290 Fairbanks Alaska can't do you want to 910 00:41:11,100 --> 00:41:09,070 cover the rest of that yes so there's 911 00:41:15,870 --> 00:41:11,110 there's two answers the question of when 912 00:41:18,540 --> 00:41:15,880 the datas will be available we want to 913 00:41:19,980 --> 00:41:18,550 give ourselves a little time to make 914 00:41:22,440 --> 00:41:19,990 sure that the measurements are 915 00:41:25,940 --> 00:41:22,450 calibrated and checked out we'll begin 916 00:41:28,470 --> 00:41:25,950 releasing uncalibrated unvalidated data 917 00:41:32,280 --> 00:41:28,480 six months after launch that'll be the 918 00:41:35,040 --> 00:41:32,290 basic radar and radiometer data the the 919 00:41:38,580 --> 00:41:35,050 calibrated radiometer and radar data 920 00:41:41,850 --> 00:41:38,590 will be released nine months after 921 00:41:45,060 --> 00:41:41,860 launch and as I mentioned earlier in the 922 00:41:47,670 --> 00:41:45,070 briefing the soil moisture data the 923 00:41:50,460 --> 00:41:47,680 unvalidated data will be released nine 924 00:41:52,650 --> 00:41:50,470 months after launch and the calibrated 925 00:41:54,980 --> 00:41:52,660 data will be released 15 months after 926 00:41:57,960 --> 00:41:54,990 launch now once the data starts flowing 927 00:42:00,510 --> 00:41:57,970 it will be sent to the DAC on an ongoing 928 00:42:02,490 --> 00:42:00,520 basis every day the satellite will 929 00:42:04,860 --> 00:42:02,500 download 930 00:42:07,770 --> 00:42:04,870 large amounts of global soil moisture 931 00:42:11,430 --> 00:42:07,780 data its pipeline directly to JPL and 932 00:42:14,510 --> 00:42:11,440 Goddard for science data processing and 933 00:42:19,320 --> 00:42:14,520 it will be released to the the dax 934 00:42:21,510 --> 00:42:19,330 within a matter of 24 hours to 36 hours 935 00:42:22,950 --> 00:42:21,520 depending on what level of data we're 936 00:42:26,130 --> 00:42:22,960 talking about so there'll be a 937 00:42:28,770 --> 00:42:26,140 continuous ongoing flow of delivered 938 00:42:30,420 --> 00:42:28,780 data going to both the both of the dax i 939 00:42:32,100 --> 00:42:30,430 spend one of the objectives of the 940 00:42:34,620 --> 00:42:32,110 mission to get the data from the 941 00:42:36,360 --> 00:42:34,630 satellite to the DAC as quickly as we 942 00:42:39,060 --> 00:42:36,370 can because we know that there's a lot 943 00:42:42,360 --> 00:42:39,070 of interest in having very fast access 944 00:42:44,250 --> 00:42:42,370 to near real-time data alright we have 945 00:42:46,080 --> 00:42:44,260 time for one more social media question 946 00:42:48,630 --> 00:42:46,090 alright this last question comes from 947 00:42:51,890 --> 00:42:48,640 twitter user Frankie who asks how do you 948 00:42:56,130 --> 00:42:51,900 counteract the spin of the reflector 949 00:42:59,070 --> 00:42:56,140 okay so I'll take that we have very 950 00:43:01,920 --> 00:42:59,080 large reaction wheels inside the 951 00:43:04,200 --> 00:43:01,930 spacecraft bus you don't see them from 952 00:43:06,450 --> 00:43:04,210 from the outside view but they're 953 00:43:09,200 --> 00:43:06,460 basically very large wheels that spend 954 00:43:11,610 --> 00:43:09,210 very fast they're like a gyroscope and 955 00:43:14,610 --> 00:43:11,620 and that's how we counteract the 956 00:43:16,800 --> 00:43:14,620 momentum of the large spinning reflector 957 00:43:19,920 --> 00:43:16,810 very good question it was something we 958 00:43:23,250 --> 00:43:19,930 was one of the early design trades that 959 00:43:25,260 --> 00:43:23,260 we considered very carefully and it's a 960 00:43:28,350 --> 00:43:25,270 great great insight to think to ask that 961 00:43:31,380 --> 00:43:28,360 question so very good any more questions 962 00:43:33,540 --> 00:43:31,390 for me to you here in the room all right 963 00:43:35,910 --> 00:43:33,550 in that event we're going to pause just 964 00:43:38,070 --> 00:43:35,920 long enough to change the participants 965 00:43:41,700 --> 00:43:38,080 on the Dyess so that we can discuss the 966 00:43:44,070 --> 00:43:41,710 cube SATs and the spacecraft that are 967 00:43:46,380 --> 00:43:44,080 also flying on the delta to second stage
