DNA TV Show: Chandrayaan-3 only 163 km away from Moon, nears touchdown

Now, we are almost at the same distance from the moon as the distance between Delhi to Mathura or Delhi to Kurukshetra. According to the plan, Chandrayaan-3 will try to land while rotating in different orbits on the Moon. This soft landing will happen on August 23. If seen, the distance between the Moon's surface and Chandrayaan-3 is only about 163 km. 

Chandrayaan-3 was to revolve in 5 different orbits in the Lunar orbit. Today, it has entered the last i.e. fifth grade before soft landing. Now, after circling here, Chandrayaan-3 will attempt a soft landing.

Tomorrow is a very important day for Mission Chandrayaan-3. Actually today, it has taken entry into the fifth orbit of the Moon. But tomorrow, it will take the first step to land on the surface of the Moon. We want to give you some special information about the lunar orbit, because to understand what we will tell you after this, it is very important for you to know that there are 2 types of lunar orbit for Chandrayaan.

The first is an Elliptical orbit and the second is a Circular orbit.

Till now, we have been telling you about the LUNAR ORBIT, we meant that Chandrayaan-3 was revolving in the Elliptical orbit of the Moon.

On August 5, Chandrayaan-3 reached the Moon's first Elliptical orbit. You can consider this as the first orbit of the Moon. Here, the speed of Chandrayaan was reduced. Here, the closest distance between Chandrayaan-3 and the Moon was 164 kilometers and the maximum distance was 18,074 km. That is, it was the largest Elliptical orbit for Chandrayaan-3.

The elliptical orbit of Chandrayaan-3 was changed on August 6. Now, Chandrayaan-3 has reached the fourth orbit of the Moon. Here, its nearest distance was 170 kilometers and the maximum distance was 4,313 km. 

On August 9, the Elliptical orbit of Chandrayaan-3 was reduced again. This time Chandrayaan-3 was sent to the third orbit of the Moon. Here the nearest distance became 174 km and the maximum distance reached was 1,437 km.

After this, on August 14, Chandrayaan-3 reached the fourth orbit, where the closest distance was 150 kilometers and the maximum distance was 177 kilometers.

After this, today i.e. on August 16, Chandrayaan-3 reached its fifth orbit, where its closest distance from the Moon's surface has reached 153 kilometers and the maximum distance has reached 163 kilometers.

Now, from here, the Lander Module of Chandrayaan-3 will start its process to go to the surface of the Moon. First of all the Propulsion Module attached to Chandrayaan-3 has to be separated.

Chandrayaan's Propulsion and Lander modules will be separated in the Moon's fifth Elliptical orbit on August 17.

The Lander Module itself has to land on the Moon. After separating from the lander of Chandrayaan-3, the Propulsion Module will continue to revolve around the Moon.

During this, the Propulsion Module will continue to collect information about the radiation coming from the Earth.

After this, the lander of Chandrayaan-3 will continuously reduce its distance from the surface of the moon for a soft landing on the moon. But here, Chandrayaan-3 will revolve in the circular orbit of the Moon. We told you that Chandrayaan-3 will orbit the Moon in two ways.

When Lander and Propulsion Module will separate. So, after that, both of them will start revolving around the moon in a circular orbit.

While revolving in a circular orbit, the distance of Chandrayaan from the surface of the Moon will be 100 kilometers.

Elliptical orbit has the maximum and closest distance.

But the distance in the circular orbit will remain 100 kilometers from each side, that is, Chandrayaan-3 will be at a height of 100 kilometers from the surface of the Moon.

After this, the speed of Chandrayaan-3 will be continuously reduced in the circular orbit itself.

Once the distance between Chandrayaan-3 and the Moon's surface is less, then the last phase of the soft landing will begin where on August 23, the Lander Module will land near the South Pole of the Moon.

Now the question is that when the Lander Module of Chandrayaan-3 will go into the Circular Orbit, then how will it do a soft landing on the surface of the Moon?

In the circular orbit, the speed of Chandrayaan's lander module will be continuously reduced.

De-orbiting will happen between August 18-20. The Propulsion Module will continue to revolve in the Circular Orbit at a distance of 100 kilometers from the Moon, but the path of the Lander Module will be separated.

After the separation of the Lander Module, it will once again revolve in the Elliptical orbit i.e. the elliptical orbit of the Moon.

During this, the maximum distance of Chandrayaan-3's Lander Module from the Moon's surface will be 100 km and the minimum distance will be 30 km.

On August 23, soft landing of the Lander Module will be done on the surface of the Moon, but the question is that when our Chandrayaan-3 will reach the Moon on the 20th, then why is it being made to land on August 23?

So, one answer to this is that it will be dark on the moon on August 20, and Chandrayaan-3 has not been prepared to land in the dark, that's why a soft landing can be done on the 23 after the sunlight comes. Solar panels have been installed in Chandrayaan-3, which is why the sunrise will be awaited.

Not only this, the speed of the lander module will also decrease during these three days. Three days' time has been fixed for these things.
