Chandrayaan 3: Quick Information About Chandrayaan for Students

In order to demonstrate end-to-end capability in safe landing and wandering on the lunar surface, Chandrayaan-3 is a follow-up mission to Chandrayaan-2. It is configured with Landers and Rovers. LVM3 will launch out of SDSC SHAR in Sriharikota. The lander and rover configuration will be propelled by the propulsion module up to a 100-kilometre lunar orbit. To examine the spectral and Polarimetric data of Earth from the lunar orbit, the propulsion module is equipped with the Spectro-Polarimetry of Habitable Planet Earth (SHAPE) payload.
