Re: Chandrayan-2 Mission

ISRO can release more detailed telemetery data and timelines in its website if it is OK with the powers that be. What happened to the lander? We know that the Moon's environment is super hostile. Did that environment have a role to play in the lander's failure? Did one of the 800KN engines under per...
