Chandrayaan-3 landing: All you need to know about the mission, what happens after it lands on the Moon

 Subsequent analyses reported that there were both software and hardware problems in 2019’s Chandrayaan-2. Isro chairperson S Somanath recently said the changes to the current mission were “failure-based.” He said, “Instead of a success-based design in Chandrayaan-2, we are doing a failure-based design in Chandrayaan-3 —we are looking at what can go wrong and how to deal with it.” Some of the changes that have been made are:

*Chandrayaan-2 lost control over its descent around 7.2 km from the surface of the Moon. Its communications system relayed data of the loss of control up to around 400 m above the surface. The Lander had slowed down to about 580 km/hr when it crashed.

A Lander does not have wheels; it has stilts, or legs, which are supposed to touch down on the lunar surface, the legs of Chandrayaan-3 have been strengthened to ensure that it would be able to land, and stabilise, even at a speed of 3 m/sec, or 10.8 km/hour.
