Once the deboosting manoeuvre of Chandrayaan-3 spacecraft's Lander "Vikram" begins, the lander will be in 'automatic mode' and will decide, based on data and with its own intelligence, how to go about its functions, Kailasavadivoo Sivan, the former chairman of Indian Space Research Organisation (ISRO), explained today. Speaking to NDTV, Mr Sivan said there's always some redundancy in sensors and other systems, which will allow the lander to work according to the intelligence built into the system.
