The Venera 7 (Russian: Венера-7) (manufacturer's designation: 3V (V-70)) was a Soviet spacecraft, part of the Venera series of probes to Venus. When it landed on the Venusian surface, it became the first man-made spacecraft to successfully land on another planet and to transmit data from there back to Earth.

- 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 / 5°S 351°E / -5; 351.[1]
The capsule antenna was extended, and signals were returned for 35 minutes. Venera 7 suddenly went silent. However, recording tapes kept rolling. A few weeks later, another 23 minutes of very weak signals were found on them. The spacecraft had landed on Venus, probably bounced onto its side on landing, and the medium gain antenna was not pointed correctly for strong signal transmission to Earth.[2]
