00:00:00,320 --> 00:00:05,280
The countdown to our Artemis I Moon mission …
A Moon-observing small satellite\h\h

2
00:00:05,280 --> 00:00:09,840
hitching a ride on Artemis I …
And some other tiny satellites that could help\h\h

3
00:00:09,840 --> 00:00:15,920
us better prepare for space weather … a few of the\h
stories to tell you about – This Week at NASA!
 \h

4
00:00:16,880 --> 00:00:23,520
We are targeting Thursday, Aug. 18 for the rollout\h
of the Space Launch System or SLS rocket and Orion\h\h

5
00:00:23,520 --> 00:00:30,560
spacecraft to Launch Pad 39B at our Kennedy Space\h
Center. We will provide a live stream of the move\h\h

6
00:00:30,560 --> 00:00:36,800
on the NASA Kennedy You Tube channel. The SLS and\h
Orion are targeted for a no earlier than Monday,\h\h

7
00:00:36,800 --> 00:00:42,320
Aug. 29 liftoff on the uncrewed Artemis\h
I test flight around the Moon and back.\h\h

8
00:00:42,880 --> 00:00:47,760
The test flight is the first in a series\h
of increasingly complex missions to help\h\h

9
00:00:47,760 --> 00:00:53,840
us establish a long-term presence on the Moon in\h
preparation for sending astronauts on to Mars.
 \h

10
00:00:54,640 --> 00:01:00,640
NASA’s Lunar IceCube, a water-scouting CubeSat,\h
is preparing to hitch a ride to the Moon as part\h\h

11
00:01:00,640 --> 00:01:06,800
of our uncrewed Artemis I mission. The small\h
lunar-orbiting satellite will use a spectrometer\h\h

12
00:01:06,800 --> 00:01:12,640
to investigate lunar ice on the surface of the\h
Moon. Scientists are interested in the absorption\h\h

13
00:01:12,640 --> 00:01:18,480
and release of water from the Moon’s rocky\h
and dusty surface – or regolith. Lunar IceCube\h\h

14
00:01:18,480 --> 00:01:24,720
will also study the exosphere — a very thin\h
atmosphere-like volume surrounding the Moon. By\h\h

15
00:01:24,720 --> 00:01:30,320
understanding the dynamics of water and other\h
substances on the Moon, scientists will be able\h\h

16
00:01:30,320 --> 00:01:36,640
to predict seasonal changes for lunar ice that\h
could impact its use as a resource in the future.
 \h

17
00:01:36,640 --> 00:01:43,040
The first of six toaster-size satellites for\h
our Sun Radio Interferometer Space Experiment or\h\h

18
00:01:43,040 --> 00:01:49,680
SunRISE has been completed. The tiny satellites\h
will combine to form a 6-mile-wide telescope in\h\h

19
00:01:49,680 --> 00:01:56,080
space capable of detecting bursts of radio\h
waves from the Sun’s superheated atmosphere,\h\h

20
00:01:56,080 --> 00:02:02,400
known as the corona. SunRISE will help scientists\h
better understand explosive space weather events.\h\h

21
00:02:02,960 --> 00:02:07,120
These phenomena generate particle\h
radiation that can jeopardize\h\h

22
00:02:07,120 --> 00:02:13,600
astronauts and technology in space and adversely\h
affect communications and power grids on Earth.\h\h

23
00:02:13,600 --> 00:02:19,920
SunRISE is targeted for launch in 2024.
On Aug. 11, we transferred ownership and\h\h

24
00:02:19,920 --> 00:02:27,200
operational control of the Earth-observing Landsat\h
9 satellite to the U.S. Geological Survey or USGS.\h\h

25
00:02:27,840 --> 00:02:33,920
Landsat 9 is the most recent in the Landsat series\h
of remote-sensing satellites, which provide global\h\h

26
00:02:33,920 --> 00:02:39,600
coverage of landscape changes on our home\h
planet. The Landsat program – a joint effort\h\h

27
00:02:39,600 --> 00:02:46,240
between NASA and USGS – recently marked 50 years\h
of continuous service observing Earth from space.

28
00:02:46,800 --> 00:02:52,400
Seeing Earth from space with your own eyes\h
is a unique experience. But this recently\h\h

29
00:02:52,400 --> 00:02:59,120
released ultra-high-definition video might just\h
be the next best thing. Imagery in the video was\h\h

30
00:02:59,120 --> 00:03:06,320
captured between April and October 2021 during the\h
Expedition 65 crew’s time aboard the International\h\h

31
00:03:06,320 --> 00:03:15,120
Space Station. Check it out for yourself and\h
download if you like at go.nasa.gov/earthviews4k.

32
00:03:15,120 --> 00:03:21,040
A quick note about an upcoming change for NASA\h
Television. NASA TV programming on the Galaxy\h\h

33
00:03:21,040 --> 00:03:26,720
13 domestic satellite is moving from\h
transponder 11 to transponder 15.\h\h

34
00:03:27,280 --> 00:03:33,600
Currently, both transponders are active, but\h
distribution of NASA TV programming on transponder\h\h

35
00:03:33,600 --> 00:03:42,400
11 will end on Monday, Aug. 29. For complete\h
