The mission has been configured based on the lessons learnt from Chadrayaan-2. Earlier, Isro Chairman K Sivan had said Chandrayaan-3 would have a similar configuration to the Chandrayaan-2, which he described as the most complex mission attempted by Isro.
The revised configuration takes care of the robustness in design and capacity enhancement for flexibility. Isro had aimed to land on the south pole of Moon — on a spot that no other landing craft had reached before.
Isro will attempt to launch in the same area, and would have a lander, rover and propulsion module like its predecessor. The spacecraft would cost around Rs 610 crore, including Rs 360 crore for the launch rocket.
