ISRO has started work on Chandrayaan-4 mission to advance Chandrayaan-3 mission. The Indian Space Research Organization has released a latest update about the mission, detailing how Chandrayaan-4 will work. It is also said that Chandrayaan-3 had only 3 modules, while Chandrayaan-4 will have five modules. Which will be used one after the other from soft landing to sample collection and safe return. Recently ISRO chief S Somnath also shared information about the mission.

Chandrayaan-4 will be launched after India's much-awaited space mission Gaganyaan. It is believed that it may take four years for India to complete this mission, but with the speed with which ISRO is working, it may be completed before the scheduled time. Now ISRO has given the latest information about the Chandrayaan-4 mission in a social media post explaining the modules, their engines and their features.

This will be the process from launch to return

The Chandrayaan-4 mission is a joint ISRO mission with Japan's JAXA, so it can be launched from Japan's H3 rocket. It will carry five modules with it. It will have an ascender module, a descender module, a propulsion module, a transfer module and a reentry module. Each module will have a different function. Most importantly, this mission will be launched in two phases. It will first be launched from Earth, land on the Moon and collect rock samples there, and then be relaunched from the surface of the Moon to re-enter Earth. Chandrayaan-4 will have a total weight of 5200 kg at the time of its first launch, while its weight will be kept at 1527 kg when it is launched from the Moon towards the Earth, so that it can easily enter the Earth's orbit.

Which module will do what?

Propulsion Module: After separation from the rocket, the propulsion module will be responsible for everything from Earth orbit to entry into lunar orbit. This module performed the same responsibility during Chandrayaan-3 as well.

Descender Module: This module will be responsible for taking all the modules to the lunar surface after separation from the propulsion module.

Ascender Module: After collecting the samples it will fly off the lunar surface and reach Earth orbit with the transfer module.

Transfer Module: This module will be responsible for taking the samples collected from the Moon back to Earth.

Re-entry module: The re-entry module will be responsible for taking the samples taken from the moon and safely landing them on Earth.

Chandrayaan-3 had three modules

India's recent successful lunar mission Chandrayaan-3 had three modules, namely the propulsion module, the lander module and the rover module. The propulsion module played the role of moving the lander into lunar orbit. The lander module made a soft landing and the rover collected data from the moon.
