Venera 10 Mission to Venus

Goals: Like its twin, Venera 9, the Venera 10 mission called for an orbiter and a lander to explore Venus. The orbiter was to act as a communications relay and study Venus from above while the lander descended via parachute to study and photograph the planet's surface.

Accomplishments: Venera 10 arrived at Venus three days after its twin. Though 2,200 km (1,367 miles) closer to the equator than Venera 9, the Venera 10 lander measured a temperature only 5°C (9°F) hotter. Atmospheric pressure at the surface was found to be 92 times that of Earth at sea level. As in the Venera 9 mission, the orbiter served as a communications relay for the lander while imaging the atmosphere in ultraviolet light and conducting other experiments. The lander transmitted data for a then record 65 minutes, including a panoramic picture of Venus' surface. Gamma ray readings suggested a basaltic surface in agreement with measurements by Venera 9, though the landscape appeared to be older than that of Venera 9's landing site.

Fast Facts
Venera 10 Facts gravity acceleration as high as 168 g and temperatures as high 12,000°C during its descent to Venus.

Images (right) show the spacecraft landed in a smoother region than its twin Venera 9.

Venera 10 landed closer to the equator than Venera 9 but found temperature differences of only a few desgress.
