00:00:00.066 --> 00:00:03.236
From the narrow field of view
astrophysics observations,

2
00:00:03.503 --> 00:00:07.140
we’ve learned that our
magnetosphere emits X-rays.

3
00:00:07.140 --> 00:00:09.342
Which resulted in
this LEXI mission.

4
00:00:09.342 --> 00:00:13.580
And I'm excited that LEXI will
give us image from the lunar surface –

5
00:00:13.580 --> 00:00:15.548
that fantastic location.

6
00:00:15.548 --> 00:00:18.251
Before NASA returns
humans to the Moon

7
00:00:19.519 --> 00:00:21.755
we are sending lots of
science and technology

00:00:21.821 --> 00:00:24.791
CLPS: Commercial Lunar Payload Services

00:00:24.791 --> 00:00:28.261
Hi. I'm Hyunju Connor,
co-investigator of the

10
00:00:28.261 --> 00:00:32.399
Lunar Environment
Heliospheric X-ray Imager, LEXI.

11
00:00:32.399 --> 00:00:36.970
LEXI is a wide field of view
soft X-ray telescope

12
00:00:36.970 --> 00:00:39.973
that will be deployed
to the lunar surface.

13
00:00:40.273 --> 00:00:43.777
LEXI is designed to study
magnetic reconnection,

14
00:00:43.777 --> 00:00:48.948
the process that allows solar wind energy
to enter the Earth's magnetosphere.

15
00:00:49.783 --> 00:00:52.652
Changes in solar wind
conditions can trigger

16
00:00:52.652 --> 00:00:55.488
different types of
magnetic reconnection,

17
00:00:55.488 --> 00:01:00.126
modifying the shape and
position of the Earth's magnetosphere.

18
00:01:01.061 --> 00:01:03.897
These solar wind particles
can be energized

19
00:01:03.897 --> 00:01:07.434
in creating space hazards
for Artemis astronauts.

20
00:01:07.700 --> 00:01:11.905
And LEXI will be the first wide
field of view telescope

21
00:01:11.905 --> 00:01:14.340
in observing this
global interaction

22
00:01:14.340 --> 00:01:17.777
between solar wind  and
Earth's magnetosphere.

23
00:01:18.812 --> 00:01:23.249
Unlike the gigantic X-ray telescopes
sent by astrophysicists,

24
00:01:23.249 --> 00:01:25.718
LEXI is a small telescope.

25
00:01:26.052 --> 00:01:29.355
To get the global view
of the magnetosphere

26
00:01:29.355 --> 00:01:32.225
it's better to be far
distant from the Earth.

27
00:01:32.225 --> 00:01:35.962
The Moon provides the perfect place
to take the global picture.

28
00:01:36.162 --> 00:01:41.034
So, understanding the solar wind
and Earth's magnetosphere interaction

29
00:01:41.301 --> 00:01:44.404
is crucial for space exploration.

30
00:01:44.938 --> 00:01:49.008
LEXI’s image will advance this
understanding of global

31
00:01:49.008 --> 00:01:52.312
interaction between the solar wind
and the magnetosphere.

32
00:01:52.745 --> 00:01:55.181
Commercial Lunar Payload Services

33
00:01:55.181 --> 00:01:58.118
NASA and American
companies working together.
