Chandrayan: Chandrayaan -3 project director P Veeramuthuvel said

Chandrayaan -3 project director P Veeramuthuvel said ISRO may use nuclear resources to maintain instruments in future rovers. ISRO officials later said the RHUs could not be installed on Chandrayaan -3's Vikram lander and Pragyan rover because it would have increased their mass. Following the success of Chandrayaan -3, ISRO is now turning its attention to Chandrayaan -4, a lunar sample-return mission. This ambitious project aims to achieve a soft landing on the Moon, collect lunar rock samples, and return them to Earth. Chandrayaan -3 is a follow-on mission to Chandrayaan -2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface. It consists of Lander and Rover configuration. Chandrayaan -1, India's first mission to Moon, was launched successfully on October 22, 2008 from SDSC SHAR, Sriharikota. The spacecraft was orbiting around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon.
