international space station

8
00:00:28,470 --> 00:00:25,279
dragon demonstrated its ability to

9
00:00:30,630 --> 00:00:28,480
maneuver and birth to the iss then make

10
00:00:32,389 --> 00:00:30,640
its safe return to earth

11
00:00:34,950 --> 00:00:32,399

development program

23
00:01:13,750 --> 00:01:12,159
you have now allowed nasa to take time

24
00:01:15,190 --> 00:01:13,760
to start developing

25
00:01:16,630 --> 00:01:15,200
vehicles that are going to get us beyond

26
00:01:18,630 --> 00:01:16,640
low earth orbit because we don't have to

27
00:01:20,070 --> 00:01:18,640
worry about getting people to low earth

28
00:01:22,310 --> 00:01:20,080
orbit anymore we don't have to worry

29
00:01:23,910 --> 00:01:22,320
about getting cargo and people to the

30
00:01:25,910 --> 00:01:23,920
international space station because

31
00:01:29,590 --> 00:01:25,920
companies like spacex are taking on that

32
00:01:32,870 --> 00:01:30,710
hi

00:02:11,350 --> 00:02:03,439
the launch vehicle stack may experience

46
00:02:16,390 --> 00:02:12,670
a 1

47
00:02:19,190 --> 00:02:16,400
152nd test of the j2x power pack a

48
00:02:21,670 --> 00:02:19,200
subset of the engine became the longest

49
00:02:24,790 --> 00:02:21,680
duration firing ever conducted in the

00:02:26,790 --> 00:02:24,800
stennis space center's a test complex

51
00:02:29,270 --> 00:02:26,800
surpassing the previous record by more

52
00:02:31,430 --> 00:02:29,280
than a full minute the june 8th test

53
00:02:33,990 --> 00:02:31,440
marked a milestone in the development of

54
00:02:36,229 --> 00:02:34,000
a next generation rocket engine designed

55
00:02:38,470 --> 00:02:36,239
to carry humans deeper into space than

56
00:02:41,190 --> 00:02:38,480
ever before the significance of this

57
00:02:43,589 --> 00:02:41,200
test is to look specifically at the

58
00:02:46,070 --> 00:02:43,599
pumps and what they're producing to see

59
00:02:48,150 --> 00:02:46,080
how they react in different environments

60
00:02:49,750 --> 00:02:48,160
and we're making sure that everything

61
00:02:52,630 --> 00:02:49,760
we've put on paper and that we've

62
00:02:55,830 --> 00:02:52,640
developed on computer models is working

63
00:02:58,470 --> 00:02:55,840
in real life the j2x is the first human

64
00:03:01,030 --> 00:02:58,480
rated liquid oxygen and liquid hydrogen

65
00:03:03,270 --> 00:03:01,040
rocket engine developed in 40 years

66
00:03:06,550 --> 00:03:03,280
and will provide upper stage power for

67
00:03:08,790 --> 00:03:06,560
nasa's space launch system or sls the

68
00:03:14,149 --> 00:03:08,800
heavy lift vehicle that'll send the new

nasa the louisiana small business

77
00:03:44,309 --> 00:03:41,030
nasa has narrowed the landing target for

78
00:03:46,550 --> 00:03:44,319
its most advanced mars rover curiosity

79
00:03:49,350 --> 00:03:46,560
when it sits down on the red planet in

80
00:03:51,910 --> 00:03:49,360
august the car-sized rover will now be

81
00:03:54,229 --> 00:03:51,920
closer to gale crater's mount sharp

82
00:03:56,309 --> 00:03:54,239
where it'll conduct its science

83
00:03:58,390 --> 00:03:56,319
fear of any additional risk that comes

84
00:04:00,710 --> 00:03:58,400
with putting down nearer the mountain's

85
00:04:03,110 --> 00:04:00,720
hazardous slope was overcome by

86
00:04:04,789 --> 00:04:03,120
confidence in curiosity's precision

87
00:04:07,350 --> 00:04:04,799
landing technology

88
00:04:10,630 --> 00:04:07,360
rock layers located in the mountain are

89
00:04:13,589 --> 00:04:10,640
the prime location for rover research

90
00:04:16,469 --> 00:04:13,599

organization conceived of the design

182
00:08:17,189 --> 00:08:13,919
upon which every early u.s astronaut

183
00:08:19,430 --> 00:08:17,199
would rely for his safe return to earth

185
00:08:24,230 --> 00:08:22,000
later became center director at ames but

186
00:08:27,350 --> 00:08:24,240
would be best remembered for his blunt

187
00:08:29,670 --> 00:08:27,360
body theory of re-entry aerodynamics

188
00:08:32,870 --> 00:08:29,680
