The first graduating class of Artemis astronauts
…

00:00:03,879 --> 00:00:07,339
Getting ready to Green Run our SLS rocket
…

3
00:00:07,339 --> 00:00:12,460
And intriguing discoveries in our solar system
– and beyond … a few of the stories to

4
00:00:12,460 --> 00:00:15,570
tell you about – This Week at NASA!

5
00:00:15,570 --> 00:00:21,020
We held a ceremony on Jan. 10 to honor the
first class of astronaut candidates to graduate

6
00:00:21,020 --> 00:00:23,200
under our Artemis program.

7
00:00:23,200 --> 00:00:28,130
After completing more than two years of basic
training, the graduating class – which includes

8
00:00:28,130 --> 00:00:33,290
eleven NASA astronauts and two Canadian Space
Agency astronauts – will become eligible

9
00:00:33,290 --> 00:00:38,620
for spaceflights – including to the International
Space Station, Artemis missions to the Moon,

10
00:00:38,620 --> 00:00:42,690
and ultimately missions to Mars.

11
00:00:42,690 --> 00:00:48,350
On Jan. 8, teams at our Michoud Assembly Facility
in New Orleans loaded the first Space Launch

12
00:00:48,350 --> 00:00:55,329
System or SLS rocket core stage for our Artemis
program onto the agency’s Pegasus barge.

13
00:00:55,329 --> 00:01:00,101
The core stage is headed to our Stennis Space
Center, near Bay St. Louis, Mississippi, for

14
00:01:00,101 --> 00:01:06,399
its Green Run test campaign – a comprehensive
evaluation targeted to start later this year

15
00:01:06,399 --> 00:01:11,109
that will verify it is ready for launch ahead
of our uncrewed Artemis 1 mission around the

16
00:01:11,109 --> 00:01:13,340
Moon and back.

17
00:01:13,340 --> 00:01:19,229
News highlighted in conjunction with the 235th
meeting of the American Astronomical Society

18
00:01:19,229 --> 00:01:22,929
includes several mentions about our TESS satellite.

19
00:01:22,929 --> 00:01:28,779
The observatory discovered its first Earth-size
planet in a star’s habitable zone in a system

20
00:01:28,779 --> 00:01:31,829
just over 100 light-years away from us.

21
00:01:31,829 --> 00:01:37,240
TESS also discovered its first circumbinary
planet – a planet that orbits two stars.

22
00:01:37,240 --> 00:01:40,609
That planet is about 1,300 light-years from
Earth.

23
00:01:40,609 --> 00:01:46,130
Meanwhile, our Hubble Space Telescope has
surveyed a spiral galaxy that is two-and-a-half

24
00:01:46,130 --> 00:01:51,170
times wider than our Milky Way and has 10
times as many stars.

25
00:01:51,170 --> 00:01:55,119
It may be the largest known galaxy in the
local universe.

26
00:01:55,119 --> 00:02:00,969
And the SOFIA flying observatory captured
a very detailed infrared panoramic image of

27
00:02:00,969 --> 00:02:06,259
the center of our Milky Way that could help
inform future research on the formation of

28
00:02:06,259 --> 00:02:10,590
massive stars and supermassive black holes.

29
00:02:10,590 --> 00:02:17,170
A SpaceX Dragon cargo spacecraft that left
the International Space Station on Jan. 7

30
00:02:17,170 --> 00:02:22,780
is back on Earth with almost 3,600 pounds
of science experiments and cargo.

31
00:02:22,780 --> 00:02:28,170
The returned items include the faulty battery
charge-discharge unit replaced during a spacewalk

32
00:02:28,170 --> 00:02:34,200
in October, a microgravity study on tiny aquatic
animals that are highly resistant to radiation

33
00:02:34,200 --> 00:02:40,200
on Earth, and research on rodents that could
help develop therapies to treat bone and muscle

34
00:02:40,200 --> 00:02:41,590
loss on Earth.

35
00:02:41,590 --> 00:02:46,480
Conducting science aboard the orbiting laboratory
is helping us learn how to keep astronauts

36
00:02:46,480 --> 00:02:52,400
healthy during long-duration spaceflights
to the Moon and eventually to Mars.

37
00:02:52,400 --> 00:02:57,361
During a Jan. 7 event at our Armstrong Flight
Research Center in Southern California, we

38
00:02:57,361 --> 00:03:02,750
highlighted some of the aircraft, scientific
equipment, and personnel involved in five

39
00:03:02,750 --> 00:03:07,830
new NASA airborne campaigns that we will deploy
this year across the U.S.

40
00:03:07,830 --> 00:03:12,680
The campaigns will look at a variety of Earth
processes that affect human lives and the

41
00:03:12,680 --> 00:03:13,680
environment.

42
00:03:13,680 --> 00:03:16,640
That’s what’s up this week @NASA …
