Like Venera 8, which embarked on a successful mission four days earlier, this spacecraft was to land on Venus with a design that devoted less of its mass to resisting pressure and more to thermal protection, instruments and a stronger parachute.


None. Failure of the engine that was to propel it from Earth orbit to Venus marooned the spacecraft in an elliptical orbit around Earth for more than a month until it finally reentered Earth's atmosphere.

In Depth

This was the sister craft to Venera 8 (launched four days earlier). Unfortunately, the spacecraft never left Earth orbit.

The Blok L escape stage's main engine prematurely cut off after only 125 seconds of firing due to a failure in the onboard timer. As a result, the spacecraft entered an elliptical orbit around Earth. Officially, the Soviets named the probe Kosmos 482 to disguise its true mission. The spacecraft reentered Earth's atmosphere.
