This is India's latest lunar exploration mission by ISRO, a part of the Chandrayaan programme. It involves a lander called Vikram and a rover named Pragyan, similar to Chandrayaan-2. The mission's propulsion module will function as an orbiter.

The LVM3 M4 vehicle effectively propelled Chandrayaan-3 into orbit on July 14. Once in its precise orbit, Chandrayaan-3 initiated its voyage towards the Moon. The spacecraft's condition was reported as normal.
