Just a few weeks after its 53rd launch anniversary, Cosmos 482 is expected to descend back to Earth's atmosphere between Friday, May 9 and Saturday, May 10, according to NASA. When and where the spacecraft will land though, remains unknown to officials.

A wayward Soviet spacecraft, adrift for more than half a century, will fall to Earth on Friday or Saturday, astronomers said.

Kosmos-482, a spacecraft bound for Venus in 1972, was a time capsule from the Cold War when superpowers had broad ambitions for exploring the solar system.
