Making progress on our Artemis Moon rocket
…

00:00:02,350 --> 00:00:05,180
Images from a close encounter with a Jovian
moon …

3
00:00:05,180 --> 00:00:09,360
And a ring of fire for our Moon … a few
of the stories to tell you about – This

4
00:00:09,360 --> 00:00:13,290
Week at NASA!

5
00:00:13,290 --> 00:00:17,800
Stacking and assembly activities for the agency’s
uncrewed Artemis I mission continue at our

6
00:00:17,800 --> 00:00:19,500
Kennedy Space Center.

7
00:00:19,500 --> 00:00:24,551
These activities involve lifting the Space
Launch System (SLS) rocket’s 188,000-pound

8
00:00:24,551 --> 00:00:29,730
core stage onto the mobile launcher, in between
the two solid rocket boosters.

9
00:00:29,730 --> 00:00:33,630
That will be followed by the stacking and
integration of other elements, and eventually

10
00:00:33,630 --> 00:00:36,520
the addition of the Orion spacecraft.

11
00:00:36,520 --> 00:00:41,450
The twin solid rocket boosters and the core
stage will provide more than 8.8 million pounds

12
00:00:41,450 --> 00:00:46,870
of thrust during the launch of NASA’s next-generation
Artemis Moon missions.

13
00:00:46,870 --> 00:00:52,110
Our Juno mission sent back images after its
June 7 flyby of Jupiter’s moon Ganymede,

14
00:00:52,110 --> 00:00:57,590
showing remarkable surface detail, including
craters, distinct areas of dark and bright

15
00:00:57,590 --> 00:01:01,640
terrain, and features possibly linked to tectonic
faults.

16
00:01:01,640 --> 00:01:06,520
The flyby is expected to yield insights into
the moon’s composition and makeup, including

17
00:01:06,520 --> 00:01:10,470
measurements of its radiation environment
that could benefit future missions to the

18
00:01:10,470 --> 00:01:11,710
Jovian system.

19
00:01:11,710 --> 00:01:16,320

20
00:01:16,320 --> 00:01:20,830
On June 10, people across the northern hemisphere
had a chance to experience an annular or a

21
00:01:20,830 --> 00:01:22,610
partial eclipse of the Sun.

22
00:01:22,610 --> 00:01:27,710
Canada, Greenland, and northern Russia experienced
an annular eclipse, during which the alignment

23
00:01:27,710 --> 00:01:32,150
of the Moon, Sun, and Earth are such that
there appears to be a ring of fire around

24
00:01:32,150 --> 00:01:33,150
the Moon.

25
00:01:33,150 --> 00:01:37,770
Elsewhere, including in parts of the eastern
U.S. and northern Alaska, the Moon only blocked

26
00:01:37,770 --> 00:01:39,950
a smaller portion of the Sun.

27
00:01:39,950 --> 00:01:44,460

28
00:01:44,460 --> 00:01:49,170
A SpaceX Dragon cargo spacecraft arrived at
the International Space Station on June 5,

29
00:01:49,170 --> 00:01:54,450
two days after launching from our Kennedy
Space Center.

30
00:01:54,450 --> 00:01:59,830
The Dragon delivered more than 7,300 pounds
of cargo, including the new ISS Roll-out Solar

31
00:01:59,830 --> 00:02:03,970
Arrays (iROSA) for the station, a science
experiment with squids that could help with

32
00:02:03,970 --> 00:02:09,530
protective measures to keep astronauts healthy
on long-duration space missions, a study on

33
00:02:09,530 --> 00:02:14,310
microscopic organisms called water bears,
that might help humans deal with the stress

34
00:02:14,310 --> 00:02:17,120
factors of human spaceflight, and more.

35
00:02:17,120 --> 00:02:23,280
This is SpaceX’s 22nd contracted commercial
resupply mission to the station for NASA.

36
00:02:23,280 --> 00:02:27,780
On June 9, NASA announced that two teams of
scientists from the Wake Forest Institute

37
00:02:27,780 --> 00:02:32,790
for Regenerative Medicine in Winston-Salem,
North Carolina, are the first and second place

38
00:02:32,790 --> 00:02:38,030
winners of the Vascular Tissue Challenge,
a prize competition to grow and sustain functioning

39
00:02:38,030 --> 00:02:40,100
human tissue in a lab.

40
00:02:40,100 --> 00:02:45,340
On Earth and in space, improved lab-grown
vascularized tissue could be used for better

41
00:02:45,340 --> 00:02:50,660
disease modeling and could accelerate related
research for organ transplants, as well as

42
00:02:50,660 --> 00:02:55,470
development of new therapeutics for long-term
deep space missions.

43
00:02:55,470 --> 00:03:00,220
The NASA TechRise Student Challenge is a new
STEM education-based competition that will

44
00:03:00,220 --> 00:03:06,000
kick off for the 2021-22 school year for teams
of sixth through 12th graders.

45
00:03:06,000 --> 00:03:11,740
The contest aims to inspire a deeper understanding
of Earth’s atmosphere, space exploration,

46
00:03:11,740 --> 00:03:17,520
coding, and electronics, as well as a broader
understanding of the value of test data.

47
00:03:17,520 --> 00:03:19,500
