Venera 10, spacecraft to Venus, launched 1975
June 14, 1975, the Soviet Union launched Venera 10, which contained an orbiter and a lander. The orbiter's job was to serve as a communications relay fr the lander, and to explore cloud layers and atmospheric parameters.
The lander touched down October 25 between Beta Regio and Hyndia Regio, just 3 days after Venera 9 landed and 2200 kilometers away. Venera 10 operated for 65 minutes, but it could not take panoramic pictures because one of the two camera lens failed to detach, so they had to settle for 180° panorama.
