11.25 am: Former ISRO Director D Sasikumar says that it’s possible the moon lander reached the lunar surface and did not lose contact with the ground station because it crashed.

“We have to find out from the communication data whether it is a soft landing or it is a crash landing,” Hindustan Times quoted him as saying. “In my opinion, it is not a crash landing because the communication channel is on between the lander and the orbiter. It should be intact. So, let us hope after the analysis done, we may be able to get the final figure.”

10.30 am: Congress’ Acting President Sonia Gandhi applauds the ISRO team for their “praiseworthy efforts” on the mission.”We owe a great debt to ISRO and the brilliant men and women who staff it,” she says. “Chandrayaan 2’s journey may take us slightly longer but ISRO’s history is replete with examples of their determination in the face of seemingly hopeless odds. They never give up. I have no doubt that that we will get there, if not today, then tomorrow...”

2.30 am: According to ANI, ISRO has lost communication with the lander Vikram, around 2.1 km from the lunar surface.

2 am: Scientists are briefing Prime Minister Narendra Modi, reports Hindustan Times.

1.40 am: ISRO tweets that the descent of the lander Vikram has begun.

1.30 am: The country awaits news on Chandrayaan-2. The moon lander Vikram had already detached itself on September 4, from the lunar orbiter, and had been in an elliptical orbit, which is, at its closest point, 35 km away from the surface of the moon. Vikram is due to land on the moon any time now.

There are two stages of the landing – one, the rough braking, when Vikram slows down against the moon’s gravitational pull, and the other, fine braking, when the lander gets closer to the lunar surface and finds a landing spot. As soon as the lander reaches the moon’s surface, the moon rover, Pragyan, will be released.

Indian Space Research Organisation’s Director K Sivan had said on Friday that the manoeuvre to land the rover on the moon’s surface without any injury will be “15 minutes of terror” even for top scientists at the space agency. If India achieves this, it will become the fourth country to successfully complete a soft moon landing and the first to do it in the south polar region of the moon.
