1
00:00:01,101 --> 00:00:03,903
The next commercial crew test flight to the space station …

2
00:00:03,903 --> 00:00:05,772
A new space station module …

3
00:00:05,772 --> 00:00:08,508
And another astronomical discovery by Hubble …

4
00:00:08,508 --> 00:00:10,610
a few of the stories to tell you about –

5
00:00:10,610 --> 00:00:12,379
This Week at NASA!

6
00:00:13,446 --> 00:00:16,449
NASA's Boeing Orbital Flight Test-2 mission to the

7
00:00:16,449 --> 00:00:19,386
International Space Station is the second uncrewed

8
00:00:19,386 --> 00:00:23,656
flight test of the CST-100 Starliner spacecraft

9
00:00:23,656 --> 00:00:26,026
as part of our Commercial Crew Program.

10
00:00:26,426 --> 00:00:29,462
The mission aims to demonstrate the end-to-end capabilities

11
00:00:29,462 --> 00:00:33,466
of the Starliner and the Atlas V launch vehicle and provide

12
00:00:33,466 --> 00:00:37,670
valuable data toward certifying Boeing’s crew transportation system

13
00:00:37,837 --> 00:00:41,441
for regular flights with astronauts to and from the space station.

14
00:00:42,709 --> 00:00:46,212
A few hours after the Nauka Multipurpose Laboratory Module (MLM)

15
00:00:46,212 --> 00:00:50,483
docked to the International Space Station on July 29, flight controllers

16
00:00:50,483 --> 00:00:52,585
noticed the unplanned firing of the module’s

17
00:00:52,585 --> 00:00:56,356
thrusters – which caused the station to move out of orientation.

18
00:00:56,723 --> 00:01:00,126
Ground teams worked to regain attitude control and stabilize

19
00:01:00,126 --> 00:01:03,029
the space station, and the crew was never in any danger.

20
00:01:03,463 --> 00:01:06,299
Nauka is the new science facility, docking port,

21
00:01:06,299 --> 00:01:09,502
and spacewalk airlock for the Russian segment of the station.

22
00:01:09,903 --> 00:01:12,872
Meanwhile, the Pirs module left the orbital outpost

23
00:01:12,872 --> 00:01:15,575
with a Progress spacecraft on July 26.

24
00:01:16,109 --> 00:01:19,612
Pirs had been the previous docking port for Russian spacecraft

25
00:01:19,612 --> 00:01:23,616
and airlock for Russian spacewalks since September 2001.

26
00:01:24,784 --> 00:01:27,787
New and archival data from NASA’s Hubble Space

27
00:01:27,787 --> 00:01:31,591
Telescope have helped astronomers uncover evidence of water vapor

28
00:01:31,825 --> 00:01:35,628
in the atmosphere of Jupiter's moon Ganymede for the first time.

29
00:01:35,995 --> 00:01:38,731
This water vapor forms when ice from the surface

30
00:01:38,731 --> 00:01:42,535
of this extremely frigid moon turns from solid to gas.

31
00:01:42,869 --> 00:01:47,273
Researchers believe there is an ocean about 100 miles below Ganymede’s crust

32
00:01:47,507 --> 00:01:50,410
that contains more water than all of the oceans on Earth.

33
00:01:51,744 --> 00:01:54,481
Scientists from our Jet Propulsion Laboratory

34
00:01:54,481 --> 00:01:57,617
joined international researchers to create an index

35
00:01:57,884 --> 00:02:01,855
that tracks how the world’s rainforests are responding to threats

36
00:02:01,855 --> 00:02:05,358
like our planet’s warming climate and human land use.

37
00:02:05,892 --> 00:02:09,462
These diverse ecosystems are home to more than half of the planet’s

38
00:02:09,462 --> 00:02:12,899
life forms and act as a natural slowing mechanism

39
00:02:12,899 --> 00:02:16,302
to the increasing levels of carbon dioxide in the atmosphere.

40
00:02:16,736 --> 00:02:20,140
The index could help policy makers plan for conservation

41
00:02:20,306 --> 00:02:22,509
and forest restoration activities.

42
00:02:23,443 --> 00:02:27,680
NASA has named nine winners in the Future-Scaping our Skies challenge.

43
00:02:27,981 --> 00:02:29,349
The competition, conducted

44
00:02:29,349 --> 00:02:33,219
through our Aeronautics Research Mission Directorate, asked the public

45
00:02:33,419 --> 00:02:37,790
to help envision the future of flight, taking into account how societal,

46
00:02:37,924 --> 00:02:42,962
technological, regulatory, environmental, economic, and political changes

47
00:02:42,962 --> 00:02:47,267
over the next 30 years might impact aviation, and vice versa.

48
00:02:47,800 --> 00:02:49,068
Input from the challenge

49
00:02:49,068 --> 00:02:52,438
could help us better anticipate aviation needs in the future

50
00:02:52,572 --> 00:02:56,892
and make better decisions about technology development today.

51
00:02:57,022 --> 00:02:59,546
3, 2, 1 ...

52
00:02:59,546 --> 00:03:03,883
July 26 was the 50th anniversary of the launch of astronauts

53
00:03:03,883 --> 00:03:07,687
David Scott, Al Worden, and Jim Irwin on Apollo 15,

54
00:03:07,921 --> 00:03:10,723
the fourth NASA mission to land humans on the Moon.

55
00:03:11,291 --> 00:03:14,561
The mission was also the first to use the Lunar Roving Vehicle,

56
00:03:14,561 --> 00:03:17,096
which Scott and Irwin used during their more than

57
00:03:17,096 --> 00:03:19,899
18 hours of lunar surface exploration

58
00:03:19,899 --> 00:03:23,036
while Worden orbited overhead in the command module.

59
00:03:23,203 --> 00:03:25,572
That’s what’s up this week @NASA …
