"Chandrayaan-3 Will Land Safely Even If Everything Goes Wrong": Scientist

Chandrayaan-3 Live: "Chandrayaan-3 has been stress tested, ISRO has taken care of all known unknowns," Professor Padhi said.

Chandrayaan-3's Vikram lander has an inbuilt "salvage mode" which will help it land even if every thing goes wrong, an aerospace scientist explained, pointing out that a lot of improvements have been done after Chandrayaan-2's failure. There's "absolutely no doubt" that it will land safely, he said.

"Chandrayaan-2 failed as the Vikram lander could not control its speed and it tumbled...There was an algorithm failure, which has now been corrected. Vikram Landers legs are more robust now," Professor Radhakant Padhi, Aerospace Scientist, Indian Institute of Science, Bengaluru, told NDTV.

Radhakant Padhi has been involved with the launch of both Chandrayaan 2 and 3. The Aerospace department of the Indian Institute of Science, Bengaluru, is also contributing to the moon mission.
