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 in May 1981.

Fast Facts

The probe was named Kosmos -- a designation for Earth-orbiting missions -- to conceal its true mission.

Its sister craft -- Venera 8 -- suceeded in landing on Venus.
