Super sources of a climate-warming greenhouse

And images of Earth from a passing spacecraft
… a few of the stories to tell you about

00:00:11,679 --> 00:00:13,540
– This Week at NASA!

5
00:00:13,540 --> 00:00:21,980
A strong marsquake recorded by our InSight
lander on Dec. 24, 2021, was caused by a massive

6
00:00:21,980 --> 00:00:28,289
meteoroid strike that excavated boulder-size
chunks of ice from the Martian surface.

7
00:00:28,289 --> 00:00:34,070
Evidence of this is seen in before-and-after
images of the impact site from our Mars Reconnaissance

8
00:00:34,070 --> 00:00:35,320
Orbiter.

9
00:00:35,320 --> 00:00:39,910
The EMIT mission on the International Space
Station that is studying the effects of mineral

10
00:00:39,910 --> 00:00:45,510
dust on our climate has also identified over
50 “super-emitter” sources of methane

11
00:00:45,510 --> 00:00:46,980
on Earth.

12
00:00:46,980 --> 00:00:51,620
Methane is a potent greenhouse gas that can
trap heat in our atmosphere.

13
00:00:51,620 --> 00:00:56,550
Our Lucy spacecraft took this shot of Earth,
on the right, and the Moon on the far left

14
00:00:56,550 --> 00:01:01,980
as the spacecraft approached Earth for a recent
flyby and gravity assist maneuver.

15
00:01:01,980 --> 00:01:06,300
Lucy is on its way to visit Jupiter’s Trojan
asteroids.

16
00:01:06,300 --> 00:01:12,600
NASA participated in the 15th Wernher von
Braun Symposium Oct. 26 – 28 in Huntsville,

17
00:01:12,600 --> 00:01:13,600
Alabama.

18
00:01:13,600 --> 00:01:17,970
The annual event is an opportunity for space
industry leaders and colleagues to convene,

19
00:01:17,970 --> 00:01:20,049
connect, and collaborate with each other.
