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.

A Soviet spacecraft launched in 1972 on a failed mission to Venus is believed to have crashed back onto Earth early on Saturday morning.
