The lander Vikram was to land on the moon's surface on September 7. It was 2.1 km above the moon's surface when it lost contact with the ground station at ISRO headquarters in Bengaluru.
The Vikram lander was planned to land on the far side of the moon between 1:30 am to 2:30 am on the intervening night of Friday-Saturday. This would have been followed by rover (Pragyan) roll-out between 5:30 am to 6:30 am.
The ISRO has announced that they had lost communication with Chandrayaan-2's lander, Vikram, minutes before its soft landing on the surface of the moon.
