Upgrades

ISRO has made a couple of important software and hardware-related changes to the Chandrayaan-3 mission, which will comprise a lander and rover.

Improvements

ISRO has updated Chandrayaan-3's lander with improved thrusters and stronger legs in order to avoid issues faced by Chandrayaan-2.

Cameras

Chandrayaan-3 features two "lander hazard detection and avoidance" cameras to help during the descent to the Moon's surface. Chandrayaan-2 had only one such camera.

Communications

Chandrayaan-3 will not carry an orbiter. Its propulsion module will act as a communications relay satellite and it will rely on Chandrayaan-2's orbiter for the backup relay.
