An astronaut has dropped a small mirror into space by accident, Nasa has said.
Commander Chris Cassidy lost control of the mirror while leaving the International Space Station for a spacewalk to work on batteries, and it floated away at about a foot per second, the space agency said.
The object is now just one of the vast amount of space junk that is in orbit around the Earth.
Mission Control said the mirror somehow became detached from Cassidy’s spacesuit. The lost item posed no risk to either the spacewalk or the station, NASA said.
Spacewalking astronauts wear a wrist mirror on each sleeve to get better views while working. The mirror is just 5 inches by 3 inches, and together with its band has a mass of barely one-tenth of a pound.
Cassidy and Bob Behnken, who followed him out without mishap, were conducting the first of at least four spacewalks to replace the last bunch of old station batteries.
