00:00 So, is it possible for humans to live there?
00:05 Comparatively, less atmosphere is there.
00:08 Literally, there is no atmosphere.
00:10 So, the moon gravitational is also very less compared to the earth.
00:14 So, the sun radiation is directly impacted.
00:19 If we take the earth's atmosphere, there are different types of layers.
00:24 There is troposphere, stratosphere, thermosphere, ionosphere.
00:27 But the moon has an exosphere.
00:30 In the exosphere, the plasma directly hits the moon's surface.
00:34 Because of the direct hit, the chemical composition of hydrogen and helium is a majority.
00:42 So, in the earth's atmosphere, the hydrogen and helium are an obstacle.
00:47 But in the moon's atmosphere, the atmosphere is less.
00:50 So, there is no protection.
00:52 So, there is a source of hydrogen and helium chemical composition.
00:57 If the helium concentration is high, we can use fuel in the future.
01:02 There are different types of metals.
01:05 Because the moon has no atmosphere, there are more meteorite impacts.
01:11 When meteorites impact the moon's surface, there is a chance of different types of metals like platinum and gold.
01:20 In the moon, there is an instrument called ILSA.
01:25 ILSA detects lunar seismic activity.
01:31 It detects earthquakes on the earth.
01:34 It also detects earthquakes on the moon.
01:37 It drills a 10-meter depth, takes the samples, analyses them and gives us the results.
01:43 Are all these in the rover?
01:45 Yes, there is.
01:47 It is in the lander.
01:50 There are two payloads in the rover.
01:55 They are the chemical elements for the chemical compositions.
01:59 The rover roves and checks the chemical compositions on the moon's surface.
02:04 It checks the elements in the chemical compositions.
02:08 That is the rover part.
02:10 The lander does seismic activity.
02:14 Along with seismic activity, there is a payload called Ramba.
02:18 Ramba studies the atmosphere.
02:21 It studies the composition of the atmosphere.
02:25 NASA has an equipment called LREA.
02:31 It is a laser retroreflector.
02:34 With that instrument, we can accurately measure the distance from the earth to the moon.
02:42 Along with that, it sends us the signals of the landing location.
02:51 These are the primary payloads.
02:54 There is another one called CHEST.
02:56 Quite interesting. Let's talk about it.
02:58 There are many issues.
03:00 Many people have doubts.
03:01 They are asking about the lunar rover.
03:03 What happens after the lunar rover lands?
03:05 What is the process after the soft landing?
03:07 Let's know all these interesting things.
