India’s Vikram lunar lander falls silent
India’s mission to safely put a lander and an autonomous rover on the surface of the moon ends with a sudden loss of data. Deployed by the successful Chandrayaan-2 orbiter, the Vikram lander (carrying the Pragyan rover) begins a powered descent to the lunar surface, only to cease communicating with ground controllers in India at an altitude of 2.1 kilometers. With the speed of Vikram’s descent at the time of data loss measured at 60 meters per second via telemetry, ground controllers declare it likely that Vikram crashed into the moon, resulting in the loss of the vehicle and its payload, a fate somewhat similar to that of the Israel-launched Beresheet lander earlier in the year. The orbiter continues to function, and will search for signs of water ice at the south pole of the moon.
