But the Venera mission, which launched from Kazakhstan on March 31, 1972, failed long before the Soviets could attempt to touch down on the hellscape. Something went wrong with an engine burn to put the vehicle on its Venutian trajectory, and the uncrewed spacecraft got stuck in space.

Time was, the Soviet Union fairly owned Venus. From 1961 to 1983, the U.S.’s old space race rival launched 16 probes, Venera 1 through Venera 16, that either flew by, orbited, or landed on Venus—with three of them failing en route.

A piece of space junk called Cosmos 482 is unlikely to pose a threat to people or property. But space experts say it highlights the need to stay vigilant.
