00:00:00,229 --> 00:00:04,000
A record-tying spacewalk to upgrade the space
station …

2
00:00:04,000 --> 00:00:07,580
The station crew receives a new shipment of
supplies …

3
00:00:07,580 --> 00:00:12,919
And looking forward to seeing Ingenuity take
flight on Mars … a few of the stories to

4
00:00:12,919 --> 00:00:17,140
tell you about – This Week at NASA!

5
00:00:17,140 --> 00:00:23,339
On July 21, NASA astronauts Bob Behnken and
Chris Cassidy conducted a nearly five-and-a-half

6
00:00:23,339 --> 00:00:27,099
hour spacewalk outside the International Space
Station.

7
00:00:27,099 --> 00:00:32,410
They upgraded station systems, and prepared
the outpost for future equipment to deploy

8
00:00:32,410 --> 00:00:34,530
experiments into space.

9
00:00:34,530 --> 00:00:41,770
Behnken and Cassidy have joined Michael Lopez-Alegria
and Peggy Whitson as the only other U.S. astronauts

10
00:00:41,770 --> 00:00:44,540
to complete 10 spacewalks.

11
00:00:44,540 --> 00:00:50,380
On July 23, an uncrewed Russian Progress supply
spacecraft launched to the Station from the

12
00:00:50,380 --> 00:00:52,940
Baikonur Cosmodrome in Kazakhstan.

13
00:00:52,940 --> 00:00:57,760
Several hours later it arrived with almost
three tons of food, fuel, and supplies for

14
00:00:57,760 --> 00:00:59,000
the crew.

15
00:00:59,000 --> 00:01:04,760
Our Mars 2020 mission is targeted for launch
July 30 from Cape Canaveral Air Force Station

16
00:01:04,760 --> 00:01:05,760
in Florida.

17
00:01:05,760 --> 00:01:11,410
The mission will carry the Mars 2020 Perseverance
rover to the Red Planet, and the Ingenuity

18
00:01:11,410 --> 00:01:13,340
Mars Helicopter.

19
00:01:13,340 --> 00:01:18,540
This technology demonstration, which has completed
its series of testing on Earth, will make

20
00:01:18,540 --> 00:01:23,200
history’s first attempt at powered flight
on another planet the very next time it spreads

21
00:01:23,200 --> 00:01:24,200
its wings.

22
00:01:24,200 --> 00:01:29,190
“Really our job isn’t done until we see
the same test flight being performed at Mars.

23
00:01:29,190 --> 00:01:31,890
So, next time we fly it will be at Mars.

24
00:01:31,890 --> 00:01:35,700
But that’s our ultimate goal, that’s when
we’ll go, ‘Yes!’”

25
00:01:35,700 --> 00:01:39,440
You can learn more about Ingenuity at: go.nasa.gov/marshelicopter.

26
00:01:39,440 --> 00:01:46,850
“This is emblematic of greatness that comes
from these kind of exploration initiatives.”

27
00:01:46,850 --> 00:01:52,770
Administrator Jim Bridenstine and other NASA
leaders joined a July 20 virtual discussion

28
00:01:52,770 --> 00:01:54,460
with the Space Foundation.

29
00:01:54,460 --> 00:01:59,780
The event highlighted how NASA’s Artemis
program for the Moon and our Mars Perseverance

30
00:01:59,780 --> 00:02:05,510
rover mission are helping us prepare for human
exploration of Mars.

31
00:02:05,510 --> 00:02:10,520
Technology development has already begun to
enable a crewed Mars mission as early as the

32
00:02:10,520 --> 00:02:12,040
2030s.

33
00:02:12,040 --> 00:02:18,150
Capabilities being worked on range from powerful
propulsion systems, to next generation high-tech

34
00:02:18,150 --> 00:02:23,629
spacesuits, to pressurized rovers astronauts
can live and work in for weeks.

35
00:02:23,629 --> 00:02:30,599
Check out go.nasa.gov/marstech for more about
these and other space technologies NASA is

36
00:02:30,599 --> 00:02:34,670
working on to make Mars science fiction a
reality.

37
00:02:34,670 --> 00:02:40,239
NASA’s Planetary Protection Office tries
to ensure that missions to Mars and other

38
00:02:40,239 --> 00:02:46,319
places in the solar system that might have
life, do not carry too many spores — cells

39
00:02:46,319 --> 00:02:50,780
that could re-activate and transport Earthly
bacteria.

40
00:02:50,780 --> 00:02:55,659
This is especially important for a mission
such as Mars 2020 that will collect samples

41
00:02:55,659 --> 00:02:58,120
for possible return to Earth.

42
00:02:58,120 --> 00:03:05,680
The latest episode of our “Gravity Assist”
podcast at go.nasa.gov/planetprotect has more

43
00:03:05,680 --> 00:03:12,010
about planetary protection, including what
your hand sanitizer has in common with NASA’s

44
00:03:12,010 --> 00:03:13,010
clean rooms.

45
00:03:13,010 --> 00:03:15,560
That’s what’s up this week @NASA …
