Chandrayaan-4 mission will be launched in two phases Science 4 min read

ISRO chief S Somnath informed at the National Space Science Symposium (NSSS 2024) that ISRO is preparing to launch the next lunar mission Chandrayaan-4. This mission of the Indian Space Research Organization (ISRO) will include five spacecraft modules.

Chandrayaan-4 will have five modules:

  • Unlike Chandrayaan-3, Chandrayaan-4 will consist of five main components. The five spacecraft modules used in Chandrayaan-4 are as follows:
  • Propulsion Module: Like Chandrayaan-3, the propulsion module will guide Chandrayaan-4 into the lunar orbit before separation.
  • Descender Module: This module will land on the Moon like Vikram Lander of Chandrayaan-3.
  • Ascender module: Once the samples have been collected, the ascender module will exit the lander and begin returning to Earth.
  • Transfer Module: This will be responsible for taking the ascender module out of the lunar orbit. It will return to Earth before the capsule separates with rock and soil samples.
  • Re-entry module: This capsule will land on Earth with samples of moon rocks and soil.
  • Whereas Chandrayaan-3 had three main components: lander, rover and propulsion module.

Chandrayaan-4 will be launched in two phases:

  • The five components of Chandrayaan-4 lunar mission will be launched in two phases. In the first stage, it will launch propulsion, descender and ascender modules similar to the Chandrayaan-3 mission.
  • In the second stage, the transfer and re-entry module will be launched on the Polar Satellite Launch Vehicle (PSLV). First mission utilizing two launch vehicles for a single mission.
  • ISRO chief S Somnath said that India's heaviest launch vehicle LVM-3 will launch with three components. Components include propulsion, descender, and ascender modules.
  • These will be launched like the Chandrayaan-3 mission. The transfer module and re-entry module will be launched on board the Polar Satellite Launch Vehicle (PSLV).
  • ISRO has not yet given detailed information about which launch will happen first.

Main objective of Chandrayaan-4 mission:

  • The purpose of ISRO's journey to the Moon and back is to obtain rock samples and other samples from the Moon's surface. They have to be brought back to Earth safely for scientific study. Apart from this, the main objectives of Chandrayaan-4 mission are:
    • ISRO aims to make safe and soft landing on lunar surface
    • Lunar sample containerisation
    • Rising from the surface of the moon
    • Docking and undocking in lunar orbit
    • Transferring samples from one module to another
    • Return and re-entry to Earth.
