00:00:00,300 --> 00:00:04,170
The next prelaunch rehearsal before
 launch of our Artemis I Moon mission ....

2
00:00:04,337 --> 00:00:07,140
News about some NASA
 astronomy missions ...

3
00:00:07,140 --> 00:00:10,343
And a critical milestone
 for an Earth-observing satellite ...

4
00:00:10,343 --> 00:00:13,513
A few of the stories
 to tell you about – this week at NASA!

5
00:00:14,614 --> 00:00:16,549
NASA is targeting June 18th

6
00:00:16,549 --> 00:00:20,420
for the start of the next wet
 dress rehearsal test with our Space Launch

7
00:00:20,420 --> 00:00:24,991
System rocket and Orion spacecraft
 at the Kennedy Space Center in Florida.

8
00:00:25,392 --> 00:00:28,461
The rehearsal is
 the final test needed before the launch

9
00:00:28,461 --> 00:00:31,164
of the uncrewed Artemis
 I mission around the Moon.

10
00:00:31,598 --> 00:00:35,168
The test includes an approximately two-day
 countdown, during

11
00:00:35,168 --> 00:00:38,938
which the launch teams
 will practice the operations, timelines

12
00:00:38,938 --> 00:00:42,375
and procedures that they will follow
 for the actual launch.

13
00:00:42,842 --> 00:00:46,880
For updates, follow
 along on NASA's Artemis blog

14
00:00:46,880 --> 00:00:49,282
at: blogs.nasa.gov/artemis.

15
00:00:49,916 --> 00:00:52,919
News about NASA missions
 at the 240th meeting

16
00:00:52,919 --> 00:00:57,090
of the American Astronomical Society
 included astronomers using data

17
00:00:57,090 --> 00:01:00,794
from our Hubble Space Telescope
 and other NASA observatories

18
00:01:01,094 --> 00:01:05,965
to see, for the first time,
 a dead star called a white dwarf consuming

19
00:01:05,965 --> 00:01:10,703
both rocky-metallic and icy material,
 the ingredients of planets.

20
00:01:11,104 --> 00:01:14,407
This instance of cosmic cannibalism
 can help astronomers

21
00:01:14,407 --> 00:01:17,510
learn more about the makeup of newly
 forming systems.

22
00:01:17,911 --> 00:01:22,715
Also discussed – the potential of NASA's
 Nancy Grace Roman Space Telescope.

23
00:01:23,049 --> 00:01:26,619
The telescope's unprecedented
 field of view will make it possible

24
00:01:26,619 --> 00:01:31,224
to study stellar streams in a large number
 of galaxies for the first time.

25
00:01:31,658 --> 00:01:35,061
Astronomers can use these observations
 to better understand

26
00:01:35,061 --> 00:01:38,364
how galaxies grow
 and the nature of dark matter.

27
00:01:38,932 --> 00:01:42,268
The Joint Polar Satellite System-2
 satellite, or JPSS-2

28
00:01:42,268 --> 00:01:45,505
that NASA is building
 for the National Oceanic

29
00:01:45,505 --> 00:01:50,009
and Atmospheric Administration recently
 completed its thermal vacuum testing.

30
00:01:50,510 --> 00:01:54,114
The critical test is meant to show
 that the spacecraft and its instruments

31
00:01:54,114 --> 00:01:57,784
can perform successfully in the harsh
 environment of space.

32
00:01:58,218 --> 00:02:01,321
JPSS-2 is targeted for launch November 1st

33
00:02:01,321 --> 00:02:03,990
from Vandenberg Space
 Force Base in California.

34
00:02:04,424 --> 00:02:07,026
The satellite will provide
 data to help improve

35
00:02:07,026 --> 00:02:10,430
our understanding of extreme
 weather and climate change.

36
00:02:11,097 --> 00:02:15,268
NASA's Low-Earth Orbit
 Flight Test of an Inflatable Decelerator,

37
00:02:15,268 --> 00:02:20,740
or LOFTID will ride to space on the JPSS-2
 launch as a secondary payload.

38
00:02:20,740 --> 00:02:24,177
LOFTID is a demonstration
 of a hypersonic inflatable

39
00:02:24,177 --> 00:02:27,680
aeroshell that could one day
 help land humans on Mars.

40
00:02:28,181 --> 00:02:30,850
Our Langley Research Center
 in Hampton, Virginia,

41
00:02:31,050 --> 00:02:35,288
recently hosted an event for the media
 to learn more about the technology.

42
00:02:35,288 --> 00:02:39,092
Following its launch to low-Earth orbit,
 LOFTID will inflate

43
00:02:39,092 --> 00:02:43,229
and descend back to Earth to demonstrate
 how it can slow down a spacecraft

44
00:02:43,429 --> 00:02:46,900
and help it survive the trip down
 through a planet's atmosphere.

45
00:02:47,634 --> 00:02:51,171
Congratulations to former
 NASA astronauts Dave Leestma,

46
00:02:51,504 --> 00:02:53,940
Sandy Magnus, and Chris Ferguson.

47
00:02:54,541 --> 00:02:57,010
They are the newest inductees to the U.S.

48
00:02:57,010 --> 00:02:59,078
Astronaut Hall of Fame.

49
00:02:59,078 --> 00:03:03,650
They were inducted as the Hall of Fame's
 class of 2022 during a June

50
00:03:03,650 --> 00:03:07,453
11th ceremony at the Kennedy Space Center
 Visitor Complex.

51
00:03:08,087 --> 00:03:10,223
That's what's up this week @NASA ...
