Somanath told The Times of India, a new sensor called the laser doppler velocity metre – which examines lunar terrain – has also been added. This increased its ability to travel, handle dispersion or move to an alternate landing site. Somanath also said the Chandrayaan-3 also has more fuel than the Chandrayaan-2. This was to look at failure scenarios,” Somanath said. “We did new test beds for simulation, which was not there last time. The spacecraft was also tested for ability to withstand vibrations by flying it over different terrains using a helicopter, while cranes were used to test the landing processes, he said. LVM-3 carrying Chandrayaan-2 spacecraft in 2019. Somanath told PTI the additional solar panels will allow it to ensure that it generates power no matter how it lands. “We asked if it lands with higher velocity, what will happen? Can it not land? Then we increased the vertical velocity component from 2 m/s to 3 m/s and tested it totally,” Somanath added.Įven more solar panels added to the lander. That means even at 3m/sec, the lander will not crash or break.
So how much can we increase the velocity tolerance in the available structure? We have enhanced the landing velocity to 3m/second from 2m/second. Basically, what were the deficiencies we were trying to overcome? One is the lander legs, which we expected could have withstood a higher velocity.
ISRO chairman S Somanath told The Times of India, “There are a lot of improvements on the lander. The legs have also been made stronger to allow it to land at a higher velocity.
