1
00:00:00,610 --> 00:00:03,570
A mighty powerful spacewalk outside the space
station …

2
00:00:03,570 --> 00:00:07,380
A look at the space station’s next crew
…

3
00:00:07,380 --> 00:00:12,480
And updates on our Artemis program … a few
of the stories to tell you about – This

4
00:00:12,480 --> 00:00:15,519
Week at NASA!

5
00:00:15,519 --> 00:00:20,870
On July 1, our Chris Cassidy and Bob Behnken
were outside the International Space Station

6
00:00:20,870 --> 00:00:23,740
for their second spacewalk in less than a
week.

7
00:00:23,740 --> 00:00:24,961
“You have control of the battery.”

8
00:00:24,961 --> 00:00:25,961
“I do.

9
00:00:25,961 --> 00:00:26,961
I’m in a good spot.”

10
00:00:26,961 --> 00:00:32,730
The pair continued upgrading power systems
on the station … replacing aging nickel-hydrogen

11
00:00:32,730 --> 00:00:34,430
(NiH2) batteries with new lithium-ion (Li-Ion)
batteries.

12
00:00:34,430 --> 00:00:40,680
The battery upgrades are expected to continue
on future spacewalks, with target dates and

13
00:00:40,680 --> 00:00:45,810
times to be announced once mission planners
assess the scope of the remaining work to

14
00:00:45,810 --> 00:00:47,050
be done.

15
00:00:47,050 --> 00:00:53,680
“You really feel it when you arrive at the
space station and see this hardware, and see

16
00:00:53,680 --> 00:00:56,800
these modules put together and flying in space.

17
00:00:56,800 --> 00:01:02,900
It’s one of the most incredible engineering
achievements, I think that humanity has done.”

18
00:01:02,900 --> 00:01:07,490
NASA astronaut Kate Rubins discussed her upcoming
second mission to the space station, during

19
00:01:07,490 --> 00:01:11,860
a July 1 press conference at our Johnson Space
Center in Houston.

20
00:01:11,860 --> 00:01:17,280
She was joined by Sergey Ryzhikov and Sergey
Kud-Sverchkov of the Russian space agency

21
00:01:17,280 --> 00:01:18,280
Roscosmos.

22
00:01:18,280 --> 00:01:25,950
The trio is targeted to launch to the station
Oct. 14 from the Baikonur Cosmodrome in Kazakhstan.

23
00:01:25,950 --> 00:01:30,500
NASA is working with contractor Northrop Grumman
on building Space Launch System (SLS) solid

24
00:01:30,500 --> 00:01:37,140
rocket boosters to support as many as six
additional flights, for a total of up to nine.

25
00:01:37,140 --> 00:01:41,380
Northrop Grumman is the current lead contractor
for the boosters that will launch the first

26
00:01:41,380 --> 00:01:46,509
three Artemis missions, including the one
that will land the first woman and next man

27
00:01:46,509 --> 00:01:49,550
on the Moon in 2024.

28
00:01:49,550 --> 00:01:55,640
“Three, Two, One … (explosive sound)”

29
00:01:55,640 --> 00:02:01,950
We’ve wrapped up testing on the Orion Structural
Test Article – a twin copy of the spacecraft

30
00:02:01,950 --> 00:02:06,170
- needed to verify Orion is ready for Artemis
I.

31
00:02:06,170 --> 00:02:12,200
The testing, which began in early 2017, was
designed to thoroughly evaluate Orion’s

32
00:02:12,200 --> 00:02:17,940
ability to withstand the stresses of launch,
climb to orbit, harsh conditions of deep space

33
00:02:17,940 --> 00:02:21,670
transit, and return to Earth.

34
00:02:21,670 --> 00:02:25,610
Engineers completed the Space Launch System
(SLS) rocket’s structural testing campaign

35
00:02:25,610 --> 00:02:30,780
for Artemis missions by applying millions
of pounds of force to the rocket’s liquid

36
00:02:30,780 --> 00:02:33,370
oxygen structural test tank.

37
00:02:33,370 --> 00:02:38,840
The tank failed within the parameters expected,
proving flight readiness and providing critical

38
00:02:38,840 --> 00:02:39,840
data.

39
00:02:39,840 --> 00:02:46,060
The SLS rocket, Orion spacecraft, Gateway
and Human Landing System are part of NASA’s

40
00:02:46,060 --> 00:02:50,129
backbone for Artemis – our next step in
human space exploration.

41
00:02:50,129 --> 00:02:53,200
That’s what’s up this week @NASA …
