The Venera 7 (Russian: Венера-7) was a Soviet spacecraft part of the Venera series of probes to Venus. When it landed on the surface, it became the first man-made spacecraft to successfully land on another planet and to transmit data from there back to Earth.

• Launch date/time: 1970 August 17 at 05:38 UTC
• On-orbit dry mass: 1180 kg
• Lander mass: 495 kg

It entered the atmosphere of Venus on December 15, 1970 and landed on the planet at 05:34:10 UTC of the same day. Landing coordinates are 5° S 351° E.^{[citation needed]}

The capsule antenna was extended, and signals were returned for 35 minutes. Another 23 minutes of very weak signals were received after the spacecraft landed on Venus, probably because the capsule bounced onto its side on landing and the medium gain antenna was not pointed correctly for strong signal transmission to Earth.
