Chandrayaan-3: ISRO Shares Images Of Moon's Far Side

The ISRO on Monday released images of Lunar far side area captured by the Lander Hazard Detection and Avoidance Camera (LHDAC).

This camera that assists in locating a safe landing area -- without boulders or deep trenches -- during the descent is developed by Ahmedabad-based Space Applications Centre (SAC), a major research and development centre of ISRO.

Chandrayaan-3, launched on July 14, is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface.

The ISRO said on Sunday that the Lander Module with rover in its belly is expected to touch down on the surface of the Moon around 6.04 PM on August 23.

ISRO Chairman S Somnath had said the most critical part of the landing is the process of bringing the velocity of the lander from 30 km height to the final landing, and that the ability to transfer the spacecraft from horizontal to vertical direction is the "trick we have to play" here.

He said, "the velocity at the starting of the landing process is almost 1.68 km per second, but this speed is horizontal to the surface of the moon. The Chandrayaan 3 here is tilted almost 90 degrees, it has to become vertical. So this whole process of turning from horizontal to vertical is a very interesting calculation mathematically. We have done a lot of simulations. It is here where we had the problem last time (Chandrayaan 2)."

"Extensive simulations have gone, guidance design have been changed, and a lot of algorithms have been put in place to make sure that in all these phases required dispersions are handled....to attempt to make a proper landing," he said.
