On a morning when Chandrayaan 2's lander Vikram fell just 2.1 km short of the moon, Prime Minister Narendra Modi refused to see it as a failure. "I can proudly say that the effort was worth it and so was the journey," the PM told the nation from the ISRO Control Centre in Bengaluru.

  • There would be a state of a near-complete blackout for a couple of hours after the landing. This is because the landing would cause the dust on the lunar surface to rise due to the moon's  low gravity, and would take a lot of time to settle down.

  • The lander Vikram will descend on the moon at the speed of 1.6km per second till it reaches a point beyond which it will move even slower at two metres per second. Scientists have given sufficient buffer time and have scheduled between 1:30 am and 2:30 am for the touchdown of the lander.
     
  • Jeff Bezos tweets:  
  • ISRO scientists will not resort to remote manual control of the lander while it makes the descent to the lunar surface. Instead, the lander Vikram will manage its own landing in an automated mode, using its on-board sensors to guide it to the perfect landing spot.
