APP.

63
00:02:23,409 --> 00:02:26,379
LAST WEEK WE REPORTED THAT 3

64
00:02:26,446 --> 00:02:29,082
CUBESATS WERE SHOT INTO SPACE.

65
00:02:29,148 --> 00:02:30,316
WE WANTED TO MAKE A CORRECTION.

66
00:02:30,383 --> 00:02:31,284
IT WAS THE UNIVERSITY OF

67
00:02:31,351 --> 00:02:32,519
MASSACHUSETTS AND NOT THE

68
00:02:32,585 --> 00:02:34,854
UNIVERSITY OF MICHIGAN THAT

69
00:02:34,921 --> 00:02:36,890
DEVELOPED ONE OF THE CUBESATS

70
00:02:36,956 --> 00:02:38,157
THAT WAS DEPLOYED.

71
00:02:38,224 --> 00:02:40,660
OUR APOLOGIES FOR THE ERROR.

72
00:02:40,727 --> 00:02:42,028
THAT'S SPACE TO GROUND FOR THIS

73
00:02:42,095 --> 00:02:42,462
WEEK.

00:03:11,891 --> 00:03:14,093
CURRENT ONE FROM NASA'S AMES

86
00:03:14,160 --> 00:03:15,128
RESEARCH CENTER EXPLORING THE

87
00:03:15,194 --> 00:03:17,497
USE OF FREE FLYING ROBOTS THAT

88
00:03:17,564 --> 00:03:19,365
COULD SERVE AS ASSISTANTS TO

89
00:03:19,432 --> 00:04:44,951
HUMAN ASTRONAUTS.

90
00:04:45,018 --> 00:04:46,285
THE LABORATORIES OF THE

91
00:04:46,352 --> 00:04:47,587
INTERNATIONAL SPACE STATION

92
00:04:47,654 --> 00:04:49,155
AREN'T THE ONLY PLACES ON THE

00:04:49,222 --> 00:04:51,424
VEHICLE WHERE SCIENTIFIC

94
00:04:51,491 --> 00:04:52,158
RESEARCH TAKES PLACE.

95
00:04:52,225 --> 00:04:53,893
THE OUTSIDE OF THE STATION IS

96
00:04:53,960 --> 00:04:55,995
HOME TO A NUMBER OF EXPERIMENTS,

97
00:04:56,062 --> 00:05:00,099
INCLUDING THE TOTAL SOLAR

98
00:05:00,166 --> 00:05:01,300
IRRADIANCE SENSOR WHICH IS

99
00:05:01,367 --> 00:05:02,669
CONTINUING NASA'S WORK OF

100
00:05:02,735 --> 00:05:05,772
GATHERING DATE TO HELP

101
00:05:05,838 --> 00:05:06,773
RESEARCHERS INVESTIGATING

102
00:05:06,839 --> 00:05:11,711
CHANGES TO EARTH'S CLIMATE.

103
00:05:11,778 --> 00:05:17,550
>> FOLLOW THE SUN.

104
00:05:17,617 --> 00:05:22,188
PRESENTED BY SCIENCE AT NASA.

105
00:05:22,255 --> 00:05:23,589
THE SUN.

106
00:05:23,656 --> 00:05:26,059
IT INSPIRES SONGS, WARMS US AND

107
00:05:26,125 --> 00:05:27,427
GROWS OUR FOOD.

108
00:05:27,493 --> 00:05:29,495
LIFE ON LAND AND IN THE OCEANS,

109
00:05:29,562 --> 00:05:31,397
THE DAILY WEATHER AND LONG TERM

110
00:05:31,464 --> 00:05:33,032
CLIMATE PATTERNS HAVE BEEN

111
00:05:33,099 --> 00:05:33,966
PRIMARILY BECAUSE OF THE ENERGY

112
00:05:34,033 --> 00:05:35,234
WE RECEIVE FROM OUR CLOSEST

113
00:05:35,301 --> 00:05:36,569
STAR.

114
00:05:36,636 --> 00:05:39,472
EVEN TINY VARIATIONS CAN AFFECT

115
00:05:39,539 --> 00:05:42,308
THE WORKINGS OF OUR PLANET'S

116
00:05:42,375 --> 00:05:42,975
ATMOSPHERE.

117
00:05:43,042 --> 00:05:44,811
NASA USES INSTRUMENTS TO FOLLOW

118
00:05:44,877 --> 00:05:48,181
THE SUN AND MONITOR THE AMOUNT

119
00:05:48,247 --> 00:05:49,882
OF ENERGY COMING TO US.

120
00:05:49,949 --> 00:05:54,287
LATEST INSTRUMENT TO DO SO MAKES

121
00:05:54,353 --> 00:05:56,222
THOSE MEASUREMENTS WITH

122
00:05:56,289 --> 00:05:59,025
UNPRECEDENTED ACCURACY.

123
00:05:59,092 --> 00:06:01,427
IT GATHERS INFORMATION FROM ITS

124
00:06:01,494 --> 00:06:04,230
PERCH ABOARD THE ISS.

125
00:06:04,297 --> 00:06:05,865
FLYING ON THE PLATFORM THAT THE

126
00:06:05,932 --> 00:06:07,533
LABORATORY PROVIDES HAS ALLOWED

127
00:06:07,600 --> 00:06:09,736
IT TO CONTINUE NASA'S 40 YEAR

128
00:06:09,802 --> 00:06:11,838
RECORD OF TRACKING THE SUN'S

129
00:06:11,904 --> 00:06:13,506
RADIANT ENERGY, ONE OF THE

130
00:06:13,573 --> 00:06:15,508
LONGEST AND IS MOST IMPORTANT

131
00:06:15,575 --> 00:06:17,610
RECORDS GATHERED FROM SPACE.

132
00:06:17,677 --> 00:06:19,846
OVER THE PAST SEVERAL DECADES,

133
00:06:19,912 --> 00:06:22,782
EARTH'S ICE MASS HAS DIMINISHED

134
00:06:22,849 --> 00:06:24,016
AND SEA LEVELS HAVE WRITTEN AND

135
00:06:24,083 --> 00:06:27,854
IS DROUGHT AND PAR PARTICIPATION

136
00:06:27,920 --> 00:06:28,821
PATTERNS HAVE CHANGED AND

137
00:06:28,888 --> 00:06:29,989
GROWING HAS SHIFTED.

138
00:06:30,056 --> 00:06:31,424
TO UNDERSTAND THE CAUSES,

139
00:06:31,491 --> 00:06:33,626
INCLUDING HUMAN INFLUENCES AND

140
00:06:33,693 --> 00:06:35,795
MODELS USED TO SIMULATE THE

141
00:06:35,862 --> 00:06:37,330
CLIMATE RESEARCHERS MUST KNOW

142
00:06:37,396 --> 00:06:39,365
THE AMOUNT OF INCOMING SOLAR

143
00:06:39,432 --> 00:06:40,233
ENERGY.

144
00:06:40,299 --> 00:06:42,602
PETER, THE LEAD MISSION

145
00:06:42,668 --> 00:06:45,004
SCIENTIST EXPLAINS.

146
00:06:45,071 --> 00:06:46,239
WHEN THERE IS A BALANCE FROM

147
00:06:46,305 --> 00:06:47,874
INCOMING ENERGY FROM THE SUN AND

148
00:06:47,940 --> 00:06:51,010
INFRARED RADIATION EARTH EMITS

149
00:06:51,077 --> 00:06:53,179
CLIMATE REMAINS STEADY.

150
00:06:53,246 --> 00:06:54,847
IT MEANS THAT ENERGY IS BEING

151
00:06:54,914 --> 00:06:56,215
STORED CAUSING TEMPERATURE

152
00:06:56,282 --> 00:06:57,717
INCREASES OR LOST CAUSING

153
00:06:57,784 --> 00:06:59,986
TEMPERATURE DECREASES.

154
00:07:00,052 --> 00:07:01,120
ENERGY FROM THE SUN MAKES UP

155
00:07:01,187 --> 00:07:04,690
HALF OF THE BALANCE EQUATION.

156
00:07:04,757 --> 00:07:05,925
EVEN THOUGH IT SHOWS THAT THE

157
00:07:05,992 --> 00:07:08,528
SUN'S SOLAR ENERGY OUTPUT HAS

158
00:07:08,594 --> 00:07:10,196
NOT HAD A MAJOR INFLUENCE THAT

159
00:07:10,263 --> 00:07:12,932
OUTPUT NEEDS TO BE MONITORED

160
00:07:12,999 --> 00:07:13,332
CONTINUOUSLY.

161
00:07:13,399 --> 00:07:15,368
IT IS ARGUABLY THE MOST

162
00:07:15,434 --> 00:07:16,769
IMPORTANT VARIABLE WE NEED TO

163
00:07:16,836 --> 00:07:18,938
KNOW TO UNDERSTAND CLIMATE.

164
00:07:19,005 --> 00:07:20,106
TRYING TO UNDERSTAND CLIMATE

165
00:07:20,173 --> 00:07:22,241
WITHOUT MEASURING THE SUN'S

166
00:07:22,308 --> 00:07:25,011
INPUT IS LIKE TRYING TO BALANCE

167
00:07:25,077 --> 00:07:26,946
YOUR CHECK OUT WITHOUT KNOWING

168
00:07:27,013 --> 00:07:27,780
YOUR INCOME.

169
00:07:27,847 --> 00:07:29,916
CLIMATE IS MEASURED OVER LONG

170
00:07:29,982 --> 00:07:31,250
TIME SPANS.

171
00:07:31,317 --> 00:07:32,518
UNLIKE WEATHER THAT CHANGES OVER

172
00:07:32,585 --> 00:07:34,921
SMALL TIME SCALES.

173
00:07:34,987 --> 00:07:36,823
TO BE ABLE TO CONNECT

174
00:07:36,889 --> 00:07:39,458
MEASUREMENTS, CONTINUITY AND

175
00:07:39,525 --> 00:07:42,061
ACCURACY ARE KEY.

176
00:07:42,128 --> 00:07:44,797
THERE ARE TWO SENSORS THE TOTAL

177
00:07:44,864 --> 00:07:46,566
IRRADIANCE MONITOR MEASURES ALL

178
00:07:46,632 --> 00:07:48,367
THE RADIANT ENERGY FROM THE SUN

179
00:07:48,434 --> 00:07:51,637
AND SPECTRAL RADIANCE MONITOR

180
00:07:51,704 --> 00:07:53,105
MEASURES AND IT'S DISTRIBUTED

181
00:07:53,172 --> 00:07:55,641
OVER ULTRA VIOLENT AND VISIBLE

182
00:07:55,708 --> 00:08:01,514
AND INFRARED WAVELENGTHS.

183
00:08:01,581 --> 00:08:04,650
FOR EXAMPLE, THE MEASUREMENTS OF

184
00:08:04,717 --> 00:08:07,353
THE SUN'S ULTRA VIAL LAT

185
00:08:07,420 --> 00:08:08,588
RADIATION ARE CRITICAL TO

186
00:08:08,654 --> 00:08:11,991
UNDERSTANDING THE OZONE LAYER.

187
00:08:12,058 --> 00:08:14,260
IT ABSORBS ULTRAVIOLET LIGHT AND

188
00:08:14,327 --> 00:08:17,096
THIS HEATS THE STRATOSPHERE AND

189
00:08:17,163 --> 00:08:19,065
DRIVES CHANGES THAT CAN PRO PULL

190
00:08:19,131 --> 00:08:20,499
GATE DOWN TO THE LOWEST

191
00:08:20,566 --> 00:08:23,336
ATMOSPHERE AND IMPACT CLIMATE.

192
00:08:23,402 --> 00:08:25,671

RECYCLE AND FILTER OUR WATER?

300
00:12:40,126 --> 00:12:44,964
LET'S GO.

301
00:12:45,030 --> 00:12:46,966
WE USE WATER RECOVERY AND

302
00:12:47,032 --> 00:12:48,000
FILTRATION BECAUSE IT IS

303
00:12:48,067 --> 00:12:49,902
EXPENSIVE TO LAUNCH RESUPPLY

304
00:12:49,969 --> 00:12:54,640
MISSIONS AND THE WAY TO THE

305
00:12:54,707 --> 00:12:56,308
WEIGHT OF THE WATER IS IMPORTANT

306
00:12:56,375 --> 00:12:58,444
AS WELL.

307
00:12:58,511 --> 00:13:00,613
CAN YOU IMAGINE THE WEIGHT OF

00:13:00,679 --> 00:13:01,881
THE WATER FOR A MONTH'S SUPPLY

309
00:13:01,947 --> 00:13:02,748

00:13:03,349 --> 00:13:05,217
WHAT ABOUT A YEAR OR MORE FOR

312
00:13:05,284 --> 00:13:06,418
DEEPER SPACE MISSIONS?

313
00:13:06,485 --> 00:13:09,388
THAT'S A LOT OF WATER.

314
00:13:09,455 --> 00:13:10,723
BRINGING IT WITH US IS NOT VERY

315
00:13:10,789 --> 00:13:11,423
EFFICIENT.

316
00:13:11,490 --> 00:13:13,692
ON STATION WE RECYCLE WASTE

AND SHAVE.

323
00:13:24,436 --> 00:13:25,671
IT WORKS LIKE THIS.

324
00:13:25,738 --> 00:13:27,806
WHEN WE USE THE BATHROOM, URINE

325
00:13:27,873 --> 00:13:30,543
IS COLLECTED AND PUMPED TO A

326
00:13:30,609 --> 00:13:32,578
DISTILLATION ASSEMBLY AND IT

327
00:13:32,645 --> 00:13:35,047
SPINS PULLING IT TO ITS WALLS.

328
00:13:35,114 --> 00:13:36,649
IT'S HEAT TO DO EVAPORATE WATER

329
00:13:36,715 --> 00:13:38,083
FROM THE WASTE AND THEN

330
00:13:38,150 --> 00:13:39,552
CONDENSED IN THE OUTER CHAMBER

00:13:39,618 --> 00:13:41,820
TO FORM.

332
00:13:41,887 --> 00:13:44,089
NEXT THE WATER IS PUMPED TO A

BY SWEAT AND PERSPIRATION.

336
00:13:55,034 --> 00:13:59,638
THEN IODINE IS ADDED FOR

MICROBIAL CONTROL.

338
00:14:02,374 --> 00:14:06,045

00:14:21,060 --> 00:14:22,328
PROCESS IS CLEAN DRINKING WATER

347
00:14:22,394 --> 00:14:26,932
THAT WE GET TO ENJOY EVERY DAY.

348
00:14:26,999 --> 00:14:29,201
THE RECYCLED WATER IS STERILE.

349
00:14:29,268 --> 00:14:33,505
THERE'S NO ODOR OR BAD TASTE.

350
00:14:33,572 --> 00:14:34,673

00:15:52,885 --> 00:15:53,786
YOU CAN'T FEEL IT.

382
00:15:53,852 --> 00:15:54,987
YOU DON'T KNOW THAT YOU'RE

383
00:15:55,054 --> 00:15:58,157
GETTING BOMBARDED BY RADIATION.

384
00:15:58,223 --> 00:16:03,696
BUT WE HAVE OPERATIONAL

385
00:16:03,762 --> 00:16:04,797
MEASUREMENTS THAT WE CAN MEASURE

386
00:16:04,863 --> 00:16:05,064
IT.

387
00:16:05,130 --> 00:16:07,032
>> SPACE RADIATION COMES FROM

388
00:16:07,099 --> 00:16:08,600
THREE MAJOR SOURCES.

389
00:16:08,667 --> 00:16:10,703
ONE IS THERE ARE RADIATION

390
00:16:10,769 --> 00:16:12,204
PARTICLES TRAPPED AROUND THE

391
00:16:12,271 --> 00:16:14,506
EARTH.

392
00:16:14,573 --> 00:16:16,075
THE SECOND SOURCE OF RADIATION

393
00:16:16,141 --> 00:16:18,711
IS FROM THE SUN DURING TIMES OF

394
00:16:18,777 --> 00:16:20,713
INTENSE SOLAR ACTIVITY THERE CAN

395
00:16:20,779 --> 00:16:23,549
BE SOLAR STORMS AND HIGH

396
00:16:23,615 --> 00:16:25,551
STRUCTURES OF RADIATION PROTONS

397
00:16:25,617 --> 00:16:27,619
IN PARTICULAR CAN REACH YOU.

398
00:16:27,686 --> 00:16:31,757
THE THIRD SOURCE IN SPACE IS

399
00:16:31,824 --> 00:16:33,926
GALACTIC COSMIC RADIATION AND

400
00:16:33,992 --> 00:16:36,195
THAT'S ONE WE'RE MOST CONCERNED

401
00:16:36,261 --> 00:16:37,463
WITH TO MISSION TO MARS.

402
00:16:37,529 --> 00:16:38,997
IT COMES FROM AND EXPLODING

403
00:16:39,064 --> 00:16:41,900
STARS WE CALL SUPER NOVAS.

404
00:16:41,967 --> 00:16:44,570
>> ONE OF THE COMMON

405
00:16:44,636 --> 00:16:45,270
MISCONCEPTIONS HOW DIFFERENT IT

406
00:16:45,337 --> 00:16:46,438
IS FROM THE TYPE OF RADIATION WE

407
00:16:46,505 --> 00:16:47,506
HAVE HERE ON EARTH.

408
00:16:47,573 --> 00:16:48,440
HERE ON EARTH WHEN YOU THINK

409
00:16:48,507 --> 00:16:50,109
ABOUT SITTING DOWN IN A DENTIST

410
00:16:50,175 --> 00:16:52,911
CHAIR THEY PUT SOME KIND OF LEAD

411
00:16:52,978 --> 00:16:54,213
BLANKET ON YOUR CHEST TO PROTECT

412
00:16:54,279 --> 00:16:55,714
YOU AGAINST X-RAYS.

413
00:16:55,781 --> 00:16:57,015
IN SPACE IT ACTUALLY IS VERY

414
00:16:57,082 --> 00:16:58,217
DIFFERENT.

415
00:16:58,283 --> 00:17:01,353
WE DON'T WANT HEAVY MATERIALS.

416
00:17:01,420 --> 00:17:05,224
WE WANT HYDROGEN AND WATER AND

417
00:17:05,290 --> 00:17:09,895
POLYETHYLENE.

418
00:17:09,962 --> 00:17:11,730
PARTICLE RADIATION IS BASICALLY

419
00:17:11,797 --> 00:17:13,365
EVERYTHING ON THE PERIODIC

420
00:17:13,432 --> 00:17:14,900
TABLE, HYDROGEN ALL THE WAY

421
00:17:14,967 --> 00:17:16,902
THROUGH NICKEL AND URANIUM BUT

422
00:17:16,969 --> 00:17:18,036
MOVING AT SPEEDS THAT ARE CLOSE

423
00:17:18,103 --> 00:17:19,204
TO THE SPEED OF LIGHT.

424
00:17:19,271 --> 00:17:20,072
THINKING ABOUT THE DIFFERENCES

425
00:17:20,139 --> 00:17:21,407
BETWEEN EARTH BASED RADIATION

426
00:17:21,473 --> 00:17:22,908
AND IS SPACE RADIATION, WE HAVE

427
00:17:22,975 --> 00:17:24,777
A LONG HISTORY AND DECENT AMOUNT

428
00:17:24,843 --> 00:17:27,980
OF DATA ABOUT THE BIOLOGICAL

429
00:17:28,046 --> 00:17:30,149
CONSEQUENCES OF EXPOSURE TO

430
00:17:30,215 --> 00:17:31,150
TERRESTRIAL RADIATION.

431
00:17:31,216 --> 00:17:34,653
WHERE WE LACK DATA AND WE HAVE A

432
00:17:34,720 --> 00:17:38,424
LARGE AMOUNT OF UNCERTAINTY IS

433
00:17:38,490 --> 00:17:39,425
SPACE RADIATION.

434
00:17:39,491 --> 00:17:41,927
NEXT ONGOING STEPS ARE TRY TO

435
00:17:41,994 --> 00:17:43,429
UNDERSTAND THOSE EXPOSURES

436
00:17:43,495 --> 00:17:45,097
BETTER AND THE BIOLOGICAL

437
00:17:45,164 --> 00:18:11,457
CONSEQUENCES THAT FOLLOW THEM.

438
00:18:11,523 --> 00:18:12,257
>> STUDYING THE SPACE

439
00:18:12,324 --> 00:18:13,992
ENVIRONMENT IS JUST A PART OF

440
00:18:14,059 --> 00:18:15,327
THE EFFORT FOR FUTURE SPACE

441
00:18:15,394 --> 00:18:16,328
EXPLORATION.

442
00:18:16,395 --> 00:18:18,597
NASA'S ARTEMIS PROGRAM IS ALSO

443
00:18:18,664 --> 00:18:19,965
DEVELOPING THE HARDWARE THAT

444
00:18:20,032 --> 00:18:22,067
WILL BE NEEDED TO RETURN

445
00:18:22,134 --> 00:18:23,702
ASTRONAUTS TO THE MOON IN JUST A

446
00:18:23,769 --> 00:18:25,070
FEW YEARS AND THEN TAKE THEM OUT

447
00:18:25,137 --> 00:18:26,638
INTO DEEP SPACE.

448
00:18:26,705 --> 00:18:28,140
HERE'S BREAKDOWN OF THE ELEMENTS

449
00:18:28,207 --> 00:18:30,642
THAT WILL SUPPORT NASA'S PLANS

450
00:18:30,709 --> 00:18:33,011
FOR MOVING US OUT BEYOND LOWER

451
00:18:33,078 --> 00:18:34,346
EARTH ORBIT.

452
00:18:34,413 --> 00:18:36,949
>> SO YOU WANT TO GO TO MARS?

453
00:18:37,015 --> 00:18:40,118
HOW DO WE SEND HUMANS TO DEEP

454
00:18:40,185 --> 00:18:40,385
SPACE.

455
00:18:40,452 --> 00:18:42,120
IN ORDER TO EXPLORE THE MOON,

456
00:18:42,187 --> 00:18:45,657
MARS AND BEYOND, WE NEED SAFE,

457
00:18:45,724 --> 00:18:46,925
FLEXIBLE AND POWERFUL STEMS THAT

458
00:18:46,992 --> 00:18:48,227
WILL MAKE IT ALL POSSIBLE.

459
00:18:48,293 --> 00:18:49,928
WE START WITH THE WORLD'S

460
00:18:49,995 --> 00:18:52,564
LARGEST SPACE FORCE AT KENNEDY

461
00:18:52,631 --> 00:18:54,066
SPACE CENTER WE HAVE ALL THE

462
00:18:54,132 --> 00:18:55,367
BUILDINGS AND TOOLS NEEDED TO

463
00:18:55,434 --> 00:18:56,902
ASSEMBLE AND LAUNCH SPACE

464
00:18:56,969 --> 00:18:57,836
VEHICLES AND HAVE THE TEAMS IN

465
00:18:57,903 --> 00:18:59,304
PLACE TO RECOVER THE ASTRONAUTS

466
00:18:59,371 --> 00:19:01,607
WHEN THEY COME HOME TO EARTH.

467
00:19:01,673 --> 00:19:03,175
NEXT UP WE NEED A DEEP SPACE

468
00:19:03,242 --> 00:19:04,476
ROCKET.

469
00:19:04,543 --> 00:19:05,944
THIS IS NASA'S SPACE LAUNCH

470
00:19:06,011 --> 00:19:06,445
SYSTEM.

471
00:19:06,512 --> 00:19:08,046
IT WILL BE THE MOST POWERFUL

472
00:19:08,113 --> 00:19:09,414
ROCKET NASA HAS EVER BUILT.

473
00:19:09,481 --> 00:19:11,183
AND IT HAS THE MUSCLE TO LIFT

474
00:19:11,250 --> 00:19:12,751
PEOPLE AND ALL OF THE EQUIPMENT

475
00:19:12,818 --> 00:19:14,453
NEEDED FOR MISSIONS TO NEW

476
00:19:14,520 --> 00:19:14,853
WORLDS.

477
00:19:14,920 --> 00:19:16,555
THE SPACE LAUNCH SYSTEM WILL

478
00:19:16,622 --> 00:19:18,991
BLAST OFF WITH A CREW IN THE

479
00:19:19,057 --> 00:19:19,958
ORION SPACECRAFT.

480
00:19:20,025 --> 00:19:21,927
THE MOST SPACECRAFT EVER BUILT

481
00:19:21,994 --> 00:19:24,296
FOR HUMAN EXPLORATION.

482
00:19:24,363 --> 00:19:26,398
IT PROVIDES THE LIFE SUPPORT AND

483
00:19:26,465 --> 00:19:27,232
POWER AND COMMUNICATION AND

484
00:19:27,299 --> 00:19:31,003
OTHER SYSTEMS TO TRANSPORT

485
00:19:31,069 --> 00:19:32,871
ASTRONAUTS ON A VARIETY OF

486
00:19:32,938 --> 00:19:34,172
EXPLORATION MISSIONS LIKE TO THE

487
00:19:34,239 --> 00:19:34,439
MOON.

488
00:19:34,506 --> 00:19:36,708
IN LUNAR ORBIT WE'LL LEARN TO

489
00:19:36,775 --> 00:19:38,777
LIVE AND WORK IN A DEEP SPACE

490
00:19:38,844 --> 00:19:40,078
ENVIRONMENT SOMETHING WE'VE

491
00:19:40,145 --> 00:19:40,812
NEVER DONE BEFORE.

492
00:19:40,879 --> 00:19:42,514
IN FUTURE MISSIONS NASA'S

493
00:19:42,581 --> 00:19:44,650
GATEWAY WILL BE A PLACE FOR

494
00:19:44,716 --> 00:19:46,018
ASTRONAUTS TO LIVE, WORK AND

495
00:19:46,084 --> 00:19:47,686
PREPARE FOR MISSIONS DEEPER INTO

496
00:19:47,753 --> 00:19:49,288
THE SOLAR SYSTEM.

497
00:19:49,354 --> 00:19:50,989
THERE YOU HAVE IT.

498
00:19:51,056 --> 00:19:54,960
NASA'S DEEP SPACE EXPLORATION

499
00:19:55,027 --> 00:19:55,494
SYSTEM.

500
00:19:55,561 --> 00:19:56,695

505
00:20:15,681 --> 00:20:17,149
>> ASTRONAUTS ON THE

506
00:20:17,215 --> 00:20:17,783
INTERNATIONAL SPACE STATION

507
00:20:17,849 --> 00:20:19,351
TODAY EAT THE SAME KINDS OF

508
00:20:19,418 --> 00:20:20,886
FOODS AS PEOPLE ON EARTH.

509
00:20:20,953 --> 00:20:22,254
BUT THEY PREPARE THEM

510
00:20:22,321 --> 00:20:23,088
DIFFERENTLY.

511
00:20:23,155 --> 00:20:25,624
DURING HIS FIRST LONG DURATION

512
00:20:25,691 --> 00:20:28,927
FLIGHT ASTRONAUT SHANE KIMBROUGH

00:20:31,697 --> 00:20:35,801
MOST POPULAR FOODS THE HUMBLE

516
00:20:35,867 --> 00:20:37,169
PEANUT AND BUTTER SANDWICH.

517
00:20:37,235 --> 00:20:38,537
ALTHOUGH IT'S MADE WITHOUT BREAD

518
00:20:38,604 --> 00:20:39,705
AND WITHOUT THE BENEFIT OF BEING

519
00:20:39,771 --> 00:20:45,243
A JUGGLER.

520
00:20:45,310 --> 00:20:46,645
>> HELLO, EVERYONE.

521
00:20:46,712 --> 00:20:49,281
I'LL SHOW YOU HOW TO MAKE A

522
00:20:49,348 --> 00:20:51,483
PEANUT AND BUTTER JELLY SANDWICH

523
00:20:51,550 --> 00:20:52,150
FROM THE INTERNATIONAL SPACE

524
00:20:52,217 --> 00:20:52,451
STATION.

525
00:20:52,517 --> 00:20:53,518
EVERY TIME WE EAT EVERYTHING

526
00:20:53,585 --> 00:20:54,920
WILL FLOAT AROUND IF YOU DON'T

527
00:20:54,987 --> 00:20:55,621
MANAGE IT.

528
00:20:55,687 --> 00:20:57,656
SO WE HAVE TAPE TO STICK THINGS

529
00:20:57,723 --> 00:20:59,925
ON AS WELL AS A BUNCH OF VELCRO.

530
00:20:59,992 --> 00:21:02,361
THE FIRST THING WE NEED IS A

531
00:21:02,427 --> 00:21:03,261
PIECE OF BREAD.

532
00:21:03,328 --> 00:21:04,630
UP HERE WE DON'T HAVE BREAD LIKE

533
00:21:04,696 --> 00:21:05,430
YOU DO ON EARTH.

534
00:21:05,497 --> 00:21:07,432
BUT WE HAVE TORTILLAS.

535
00:21:07,499 --> 00:21:10,235
SO WE USE THOSE A LOT FOR

536
00:21:10,302 --> 00:21:10,736
SANDWICHES.

537
00:21:10,802 --> 00:21:12,537
THAT'S WHAT I'LL USE IS FOR MY

538
00:21:12,604 --> 00:21:14,840
PEANUT BUTTER AND JELLY.

539
00:21:14,906 --> 00:21:17,142
I'LL STICK IT DOWN WITH TAPE SO

540
00:21:17,209 --> 00:21:19,845
IT DOESN'T GO FLOATING AWAY.

541
00:21:19,911 --> 00:21:22,848
I'LL GET MY PEANUT BUTTER OUT

542
00:21:22,914 --> 00:21:24,182
AND EVEN THE LIDS HAVE A PIECE

543
00:21:24,249 --> 00:21:26,985
OF VELCRO ON IT.

544
00:21:27,052 --> 00:21:28,053
IT WILL FLOAT THERE.

545
00:21:28,120 --> 00:21:30,288
FOR A LITTLE WHILE AND THEN THE

546
00:21:30,355 --> 00:21:31,289
AIR-CONDITIONING SYSTEM IN HERE

547
00:21:31,356 --> 00:21:32,991
WILL TAKE IT AWAY SOMEBODY WHERE

548
00:21:33,058 --> 00:21:33,458
ELSE.

549
00:21:33,525 --> 00:21:34,626
SO I DON'T WANT TO LOSE IT SO

550
00:21:34,693 --> 00:21:36,762
I'M STICK IT ON THE TABLE.

551
00:21:36,828 --> 00:21:38,497
I'LL SCOOP OUT SOME PEANUT

552
00:21:38,563 --> 00:21:39,965
BUTTER FOR MY SANDWICH.

553
00:21:40,032 --> 00:21:41,900
I GOT TO STICK THIS SOMEWHERE

554
00:21:41,967 --> 00:21:43,969
OTHERWISE IT GOES FLOATING AWAY

555
00:21:44,036 --> 00:21:44,770
TOO.

556
00:21:44,836 --> 00:21:48,106
IF IT'S JUST FOR A FEW SECONDS I

557
00:21:48,173 --> 00:21:49,174
CAN LEAVE IT.

558
00:21:49,241 --> 00:21:50,809
I'LL SPREAD THE PEANUT BUTTER ON

559
00:21:50,876 --> 00:21:56,581
MY SANDWICH.

560
00:21:56,648 --> 00:22:01,420
AND THEN I GET MY JELLY READY.

561
00:22:01,486 --> 00:22:02,821
A LOT OF THINGS YOU GOT TO THINK

562
00:22:02,888 --> 00:22:05,257
ABOUT IT AND MANAGE WHILE YOU'RE

563
00:22:05,323 --> 00:22:07,259
EATING UP HERE. YOU JUST SPREAD

564
00:22:07,325 --> 00:22:13,231
THE JELLY ON THE SANDWICH.

565
00:22:13,298 --> 00:22:16,401
THAT AS WELL NEEDS TO GET

566
00:22:16,468 --> 00:22:17,469
ATTACHED TO THE TABLE.

567
00:22:17,536 --> 00:22:20,338
SO THERE'S MY PEANUT BUTTER AND

568
00:22:20,405 --> 00:22:23,108
JELLY TORTILLA OR SANDWICH.

569

570

SEE IF YOU GUYS CAN ENJOY IT AS

572
00:22:30,515 --> 00:22:40,892
IT'S COMING TO YOU.

573
00:22:40,959 --> 00:22:43,428
AN EXPEDITION ON BOARD THE

574
00:22:43,495 --> 00:22:44,062
INTERNATIONAL SPACE STATION

575
00:22:44,129 --> 00:22:46,264
DOESN'T JUST LEAD TO ADVANCES IN

576
00:22:46,331 --> 00:22:48,200
SCIENCE.

577
00:22:48,266 --> 00:22:50,268
IN SOME CASES IT CAN CAUSE

578
00:22:50,335 --> 00:22:51,903
CHANGES TO SCIENTISTS WHO WORK

579
00:22:51,970 --> 00:22:53,105
THERE.

580
00:22:53,171 --> 00:22:55,207
JESSICA MEIR SAID MEETING IN

581
00:22:55,273 --> 00:22:58,243
SPACE WAS BETTER ABOUT THE DREAM

582
00:22:58,310 --> 00:22:59,544
SHE HAD WHEN SHE WAS A LITTLE

583
00:22:59,611 --> 00:23:01,012
GIRL AND FEELING LOOKING DOWN ON

584
00:23:01,079 --> 00:23:04,282
THE WHOLE WORLD OF HER PREVIOUS

585
00:23:04,349 --> 00:23:09,054
EXPERIENCE TOOK TIME TO PROCESS.

586
00:23:09,121 --> 00:23:10,856
>> FIRST GRADE WHEN WE WERE

587
00:23:10,922 --> 00:23:12,224
ASKED TO DRAW A PICTURE WHAT WE

588
00:23:12,290 --> 00:23:13,759
WANTED TO BE WHEN WE GREW UP AND

589
00:23:13,825 --> 00:23:16,661
I REMEMBER DRAWING A PICTURE OF

590
00:23:16,728 --> 00:23:19,164
AN ASTRONAUT STANDING ON THE

591
00:23:19,231 --> 00:23:21,566
SURFACE OF THE MOON, THE ICONIC

592
00:23:21,633 --> 00:23:23,034
APOLLO IMAGE NEXT TO THE FLAG ON

593
00:23:23,101 --> 00:23:24,569
THE MOON AND THAT WAS WHAT I

594
00:23:24,636 --> 00:23:26,037
DREW THEN AND SAID I WANTED TO

595
00:23:26,104 --> 00:23:27,873
BE AN ASTRONAUT AND THEN ALWAYS

596
00:23:27,939 --> 00:23:29,975
SAID IT ALL THE WAY THROUGH

597
00:23:30,041 --> 00:23:39,584
SINCE THAT TIME.

598
00:23:39,651 --> 00:23:42,254
I KNEW THAT I WAS GOING TO BE

599
00:23:42,320 --> 00:23:43,688
ECSTATIC BEING IN SPACE.

600
00:23:43,755 --> 00:23:45,791
MY LIFELONG DREAM AND I KNEW IT

601
00:23:45,857 --> 00:23:46,992
WAS GOING TO MAKE ME HAPPY.

602
00:23:47,058 --> 00:23:50,095
BUT I DIDN'T -- EVEN I DIDN'T

603
00:23:50,162 --> 00:23:51,530
EXPECT HOW INCREDIBLE IT FELT

604
00:23:51,596 --> 00:23:52,964
AND I SAID THAT A LOT TO PEOPLE

605
00:23:53,031 --> 00:23:54,666
THAT IT'S EVEN MORE INCREDIBLE

606
00:23:54,733 --> 00:23:56,935
THAN I EVER IMAGINED AND I

607
00:23:57,002 --> 00:23:57,469
REALLY MEANT IT.

608
00:23:57,536 --> 00:23:58,503
BECAUSE I THOUGHT SO MUCH ABOUT

609
00:23:58,570 --> 00:24:00,405
IT AND I 92 YOU IT WAS GOING TO

610
00:24:00,472 --> 00:24:02,040
BE THE MOST EXTRAORDINARY

611
00:24:02,107 --> 00:24:03,475
EXPERIENCE OF MY LIFE BUT I

612
00:24:03,542 --> 00:24:05,177
WASN'T EVEN PREPARED FOR HOW I

613
00:24:05,243 --> 00:24:09,080
FELT, THE LEVEL OF EXCITEMENT

614
00:24:09,147 --> 00:24:11,149
AND JUST PURE JOY I FELT ALL THE

615
00:24:11,216 --> 00:24:12,217
TIME IN THAT ENVIRONMENT.

616
00:24:12,284 --> 00:24:14,319
I REALLY FELT LIKE I WAS HOME.

617
00:24:14,386 --> 00:24:15,720
I FELT LIKE THAT'S WHERE I

618
00:24:15,787 --> 00:24:17,122
SHOULD BE AND I DON'T THINK I

619
00:24:17,189 --> 00:24:18,657
STOPPED SMILING FOR PRETTY MUCH

620
00:24:18,723 --> 00:24:26,531
THE ENTIRE 7 MONTHS.

621
00:24:26,598 --> 00:24:28,200
I WOULD FIND MYSELF THINKING,

622
00:24:28,266 --> 00:24:29,835
HOW CAN THIS BE REAL?

623
00:24:29,901 --> 00:24:31,670
THAT I'M FLOATING ABOVE THE

624
00:24:31,736 --> 00:24:35,106
PLANET AND LOOKING DOWN ON IT.

625
00:24:35,173 --> 00:24:36,541
EVEN AFTER 7 MONTHS AND KNOWING

626
00:24:36,608 --> 00:24:37,809
WHAT WE HAD DONE TO GET THERE

627
00:24:37,876 --> 00:24:39,744
AND I WORKED FOR THIS MY ENTIRE

628
00:24:39,811 --> 00:24:41,112
LIFE IT STILL IS HARD TO

629
00:24:41,179 --> 00:24:42,347
CONVINCE YOURSELF THAT IT'S

630
00:24:42,414 --> 00:24:43,849
REALLY HAPPENING WHICH MAY BE

631
00:24:43,915 --> 00:24:44,916
SOUNDS A BIT FUNNY.

632
00:24:44,983 --> 00:24:46,418
BUT EVEN AFTER 7 MONTHS JUST

633
00:24:46,484 --> 00:24:47,719
FELT HA WAY LOOKING DOWN ON THE

634
00:24:47,786 --> 00:24:48,119
EARTH.

635
00:24:48,186 --> 00:24:49,921
WOW, THIS IS REAL.

636
00:24:49,988 --> 00:24:51,957
I'M UP HERE FLOATING ABOVE THE

637
00:24:52,023 --> 00:24:52,357
EARTH.

638
00:24:52,424 --> 00:24:54,192
WHEN YOU'RE IN THE SPACE STATION

639
00:24:54,259 --> 00:24:55,994
IN THE CUPOLA, THERE ARE STARS

640
00:24:56,061 --> 00:24:57,462
ALL AROUND YOU AND YOU CAN

641
00:24:57,529 --> 00:25:01,233
REALLY FEEL IT THAT WAY.

642
00:25:01,299 --> 00:25:02,734
THAT'S A GOOD WAY TO DESCRIBE

643
00:25:02,801 --> 00:25:03,001
IT.

644
00:25:03,068 --> 00:25:06,271
YOU FEEL LIKE IT'S MORE 3

645
00:25:06,338 --> 00:25:07,505
DIMENSIONAL AND YOU GAZE OFF

646
00:25:07,572 --> 00:25:09,875
INTO IT AND IS REALLY IS JUST

647
00:25:09,941 --> 00:25:10,876
EXTRAORDINARY TO THINK ABOUT

648
00:25:10,942 --> 00:25:12,878
THAT.

649
00:25:12,944 --> 00:25:14,713
AND THEN LOOK BACK AT THE EARTH

650
00:25:14,779 --> 00:25:17,515
AND REALIZE WE'RE JUST SUCH A

651
00:25:17,582 --> 00:25:19,384
SMALL COMPONENT OF THAT.

652
00:25:19,451 --> 00:25:20,819
THIS IS WHAT HAS DRIVEN ME SINCE

653
00:25:20,886 --> 00:25:22,420
I WAS 5, WHAT IT WAS GOING TO BE

654
00:25:22,487 --> 00:25:23,688
LIKE TO HAVE THAT FEELING AND

655
00:25:23,755 --> 00:25:25,190
LOOK BACK ON THE PLANET AND

656
00:25:25,257 --> 00:25:28,727
YOU'RE NOT THERE.

657
00:25:28,793 --> 00:25:29,961
THAT'S THE PLACE WHERE

658
00:25:30,028 --> 00:25:31,162
EVERYTHING HAS HAPPENED IN YOUR

659
00:25:31,229 --> 00:25:32,264
LIFE AND EVERYTHING HAS HAPPENED

660
00:25:32,330 --> 00:25:33,465
THROUGH THE ENTIRE HISTORY OF

661
00:25:33,531 --> 00:25:35,300
THE HUMAN SPECIES AND EVERYTHING

662
00:25:35,367 --> 00:25:36,468
YOU'VE DONE AND ALL THE PLACES

663
00:25:36,534 --> 00:25:37,869
YOU'VE BEEN.

664
00:25:37,936 --> 00:25:38,970
EVERYTHING.

665
00:25:39,037 --> 00:25:41,006
IT'S DOWN THERE AND YOU'RE

666
00:25:41,072 --> 00:25:54,619
SEPARATE FROM THAT.

667
00:25:54,686 --> 00:25:57,389
IT ACTUALLY DOES LOOK DIFFERENT

668
00:25:57,455 --> 00:26:00,926
LOOKING OUT OF YOUR VISOR VERSUS

669
00:26:00,992 --> 00:26:01,559
YOUR WINDOW.

670
00:26:01,626 --> 00:26:03,762
THE COLORS ARE MORE VIBRANT AND

671
00:26:03,828 --> 00:26:05,730
MENTALLY AND PSYCHOLOGICALLY

672
00:26:05,797 --> 00:26:06,831
REALIZING THERE IS NOTHING

673
00:26:06,898 --> 00:26:09,567
BETWEEN THE VACUUM OF SPACE

674
00:26:09,634 --> 00:26:11,002
EXCEPT FOR THIS SPACE SUIT AND

675
00:26:11,069 --> 00:26:12,003
YOUR VISOR.

676
00:26:12,070 --> 00:26:13,638
THERE IS NOTHING BETWEEN YOU AND

677
00:26:13,705 --> 00:26:14,105
IT.

678
00:26:14,172 --> 00:26:16,408
AND YOU'RE REALLY OUT THERE IN

679
00:26:16,474 --> 00:26:19,177
YOUR OWN LITTLE MINI SPACECRAFT.

680
00:26:19,244 --> 00:26:20,979
IT HAS THE LIFE SUPPORT SYSTEM

681
00:26:21,046 --> 00:26:22,580
AND EVERYTHING YOU NEED TO BE

682
00:26:22,647 --> 00:26:24,849
KEPT ALIVE AND IT'S JUST YOU.

683
00:26:24,916 --> 00:26:26,584
AND YOU HAVE THIS SENSE OF JUST

684
00:26:26,651 --> 00:26:28,887
BEING BY YOURSELF IN THIS

685
00:26:28,954 --> 00:26:30,555
ENVIRONMENT WITH YOUR OWN LITTLE

686
00:26:30,622 --> 00:26:32,123
LIFE SUPPORT SYSTEM.

687
00:26:32,190 --> 00:26:33,224
I LOVE THAT FEELING.

688
00:26:33,291 --> 00:26:34,359
I DON'T KNOW WHAT IT IS EXACTLY

689
00:26:34,426 --> 00:26:37,562
ABOUT THAT IT, BUT I FEEL

690
00:26:37,629 --> 00:26:39,030
PEACEFUL AND RELAXED.

691
00:26:39,097 --> 00:26:40,899
IN THE SPACE SUIT YOU'RE LOOKING

692
00:26:40,966 --> 00:26:42,267
DOWN AND SEEING THE EARTH FROM

693
00:26:42,334 --> 00:26:45,971
ABOVE FROM THE OUTSIDE.

694
00:26:46,037 --> 00:26:48,039
WITH OUR OWN HUMAN EYES.

695
00:26:48,106 --> 00:26:54,779
IT CHANGES YOU AS A PERSON.

696
00:26:54,846 --> 00:26:56,481
WHEN YOU LOOK BACK AND YOU'RE IN

697
00:26:56,548 --> 00:27:01,319
THIS BLACKNESS OF ANY COLOR, THE

698
00:27:01,386 --> 00:27:02,721
BLACKNESS OF SPACE AND THERE'S

TOGETHER.

703
00:27:11,329 --> 00:27:13,031

704
00:27:13,098 --> 00:27:14,766
GEOPOLITICAL BOUNDARIES AND MAN
