The Lander and the Rover have scientific payloads to carry out experiments on the lunar surface. The main function of the Propulsion Module (PM) was to carry the Lander Module (LM) from the launch vehicle injection till final lunar 100 km circular polar orbit and separate the LM from PM, which it did.
The initial assessment of the first-ever measurements of the near-surface lunar plasma environment over the south pole region by RAMBHA-LP payload onboard Chandrayaan-3 lander indicates that plasma there is relatively sparse, ISRO said on Thursday.
The Chandrayaan-3 mission that aims for a soft landing on the moon's surface, paving the way for future interplanetary missions, carries six payloads that would help ISRO understand the lunar soil and also get the blue planet's photographs from the lunar orbit.

An ISRO official said: "Unless and until everything is intact (lander), it's very difficult (to re-establish contact). Chances are less. Only if it had soft-landing, and if all systems functioned, then only communication can be restored. Things are bleak as of now."
