The Venera 7 (Russian: Венера-7 meaning Venus 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, at 05:38 UTC. It consisted of an interplanetary bus based on the 3MV system and a lander.
It entered the atmosphere of Venus on December 15, 1970.
The probe transmitted information to Earth for 53 minutes, which included 20 minutes from the surface. It was found that the temperature at the surface of Venus was 475 °C (887 °F) ° ± 20 ° C and the pressure was 90 ± 15 atmospheres. The pressure corresponded to approximately 900 m below sea level. The probe provided information about the surface of Venus, which could not be seen through a thick veil of atmosphere.
The spacecraft definitively confirmed that humans cannot survive on the surface of Venus, and excluded the possibility that there is any liquid water on Venus.
