1
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

9
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.
