Chandrayaan 3 Lunar Orbit Injection: Chandrayaan-3 came in the orbit of the moon... now it just has to land

ISRO has achieved great success. Chandrayaan-3 has caught the orbit of the moon. Now Chandrayaan is traveling in an orbit of about 166 km x 18 thousand km. This is the orbit of the Moon. After this the next big day will be 17th August. When Chandrayaan-3 propulsion and lander module will separate. After this only landing will remain.

Chandrayaan-3 has captured the outer orbit of the Moon. Now Chandrayaan-3 will revolve around the moon in an elliptical orbit of 166 km x 18054 km. ISRO kept the thrusters on for about 20 to 25 minutes for Chandrayaan-3 to capture the Moon's orbit. With this, Chandrayaan got stuck in the gravity of the moon. Now he will keep circling around her.

It is also called Lunar Orbit Injection or Insertion (LOI). Five orbits will be changed around the Moon. After today, around 11 pm on August 6, Chandrayaan's orbit will be put in an orbit of 10 to 12 thousand kilometers. Its orbit will be changed to an orbit of 4 to 5 thousand kilometers on August 9 at around 2.45 pm.

It will be reduced to 1000 kms on the afternoon of 14th August. In the fifth orbit maneuver, it will be put in an orbit of 100 km. On August 17, the propulsion module and the lander module will separate. Deorbiting will happen on 18 and 20 August. That is, the distance of the moon's orbit will be reduced. The lander module will go into an orbit of 100 x 35 km. After this, Chandrayaan's landing will be done at 5.47 pm on 23rd. But the journey of 18 days is still left.

Now the speed of Chandrayaan-3 will be reduced continuously

To capture the orbit of the moon, the speed of Chandrayaan-3 was increased to around 3600 kilometers per hour. Because the gravity of the Moon is six times less than that of the Earth. If there was more speed then Chandrayaan would have crossed it. For this, ISRO scientists reduced the speed of Chandrayaan to 2 or 1 kilometer per second. Because of this speed, he was able to capture the orbit of the Moon. Now gradually the distance of its orbit around the moon will be reduced and it will be landed near the South Pole.

There is no mention of failure in the way of Chandrayaan

Look at the history... Whichever countries or space agencies sent spacecraft directly towards the moon through their rockets. They have got more disappointment. One out of three missions failed. But the path and method that ISRO has chosen, the possibility of failure in it is very less. Here is a chance to complete the mission again.

This time will not make the same mistake as last time

This time the name of the instrument which has been installed in the lander is Laser Doppler Velocitymeter (LDV) and Lander Horizontal Velocity Camera (LHVC). The Laser Doppler Velocitymeter emits a 3D laser while descending on the ground. This laser collides with the ground and tells back how the surface is. high-low bumpy Based on this, he chooses the right place for landing.

The lasers that go in the other two directions, they see that there is no high object in front or behind, due to which there is a danger of hitting the lander. Along with this works LHVC which takes picture of the lower part of the ground. That too in motion. So that the speed of landing of the lander and floating in the air like a helicopter can be known. Also, the dangers can be guessed.

Chandrayaan-3 has entered the outer orbit of the moon. Now the orbit will be changed five times. After this there will be landing.
