Moon Mission / Chandrayaan-4 will have 5 modules, this is how every work will be done from landing to return

Chandrayaan 4: To carry forward the mission of Chandrayaan-3, ISRO has started work on Chandrayaan-4 mission. A latest update has been issued by the Indian Space Research Organization about this mission, in which it has been told how Chandrayaan-4 will work. It is also told that Chandrayaan-3 had only 3 modules, whereas Chandrayaan-4 will have five modules. Which will be used one after another from soft landing to sample collection and safe return. Recently ISRO Chief S Somnath had 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, however, with the speed with which ISRO is working, it may be completed even before the scheduled time. Now ISRO has given the latest information about Chandrayaan-4 mission on social media post In this, the modules, their engines and their features are explained.

This will be the process from launching to return

Chandrayaan-4 mission is a joint mission of ISRO with Japan's JAXA, hence it can be launched from Japan's H3 rocket. It will carry five modules with itself. It will have ascender module, descender module, propulsion module, transfer module and reentry module. Each module will have a different function. The most important thing is that this mission will be launched in two phases. First it will be launched from the Earth which will land on the Moon and collect rock samples there and then after that it will be launched again from the Moon's surface which will re-enter the Earth. At the time of launching for the first time, the total weight of Chandrayaan-4 will be 5200 kg, whereas when it will be launched from the Moon towards the Earth, its weight will be kept at 1527 kg, 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's orbit to entry into the Moon's orbit. This module performed the same responsibility during Chandrayaan-3 also.

Descender Module: After separation from the propulsion module, this module will be responsible for taking all the modules to the lunar surface.

Ascender Module: After collecting samples, it will fly from the lunar surface and reach Earth's 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: Re-entry module will be responsible for taking samples taken from the moon and landing them safely on Earth.

This is what we know so far about #ISRO's Moon sample return mission Chandrayaan-4:

The mission will involve a PSLV & a LVM3 launch & consist of 5 modules - Ascender, Descender, Propulsion, Transfer & Re-entry module.

Chandrayaan-3 had three modules

India's recent successful lunar mission Chandrayaan-3 had three modules, these were propulsion module, lander module and rover module. The propulsion module played the role of taking the lander to the moon's orbit. The lander module made a soft landing and the rover collected information from the moon.
