The surface of Venus is definitely no easy place to which to send a spacecraft. Crushing atmospheric pressures, powerful high-altitude winds amid caustic clouds of sulfuric acid, and temperatures that can soar above 880ºF (475ºC) make the next planet in a no-man’s-land for robotic spacecraft. But those challenges didn’t stop the Soviet space program from successfully putting several craft onto Venus’ surface in the 70s and early 80s, giving us our first views of its kiln-dried landscape.
Venera-3 became the fist spacecraft on the surface of another planet when it impacted Venus on March 1, 1966, but no data was returned. The next year Venera-4 was sent to Venus but was likely crushed by its atmosphere. Venera-7 became the first spacecraft to successfully soft-land on Venus on Dec. 15, 1970, sending back temperature data. Venera-8 landed on…
