Venera 7

The Venera 7 was a Soviet spacecraft, part of the Venera series of probes to Venus. When it landed on the Venusian surface, it became the first spacecraft to land on another planet and first to transmit data from there back to Earth.

The probe was launched from Earth on August 17, 1970. It consisted of an interplanetary bus based on the 3MV system and a lander. During the flight to Venus two in-course corrections were made using the bus’s on-board KDU-414 engine.

It entered the atmosphere of Venus on December 15, 1970. The probe appeared to go silent on impact but recording tapes kept rolling.
