Communications between the Indian Space Research Organization (ISRO) and the Chandrayaan-2 Vikram lander were lost moments before a scheduled landing at the Moon’s south pole Sept. 6 U.S. time, during the braking phase with the spacecraft and its Pragyan rover about 2.1 km above the lunar surface.

The autonomous descent, which got under way at 4:08 p.m. EDT, was considered to be going as planned until that point. The loss of signal was reported by the ISRO control center at Istrac, Bengaluru at 4:24 p.m. EDT.
