Speaking on landing of Chandrayaan-3 on the moon, Former ISRO Scientist Yagnaswami Sundara Rajan on August 22 said that the chances of success are exceeding high. "About 80 pc changes are done (in Chandrayaan-3)...They incorporated many things into Chandrayaan-3. Earlier it was seeing only the height when it is landing, called altimeter, now in addition to that they've also added a velocity meter called doppler, so you will know the height and also velocity, so that it can control itself…The chances of success are exceeding high," YS Rajan told ANI.
