Part of the suit of a NASA astronaut came off and sailed into space.
NASA astronaut Chris Cassidy has lost his wrist mirror while floating outside the International Space Station (ISS) during the first out of four planned spacewalks to replace aging batteries in the solar power system, the U.S. spaceflightnow.com outlet said on Saturday.
Commander Chris Cassidy said the mirror quickly floated away.
Right now, the mirror will be one of the vast collections fo space junk that orbit around the planet.
As the spacewalk ended, Cassidy thanked the cleaning staff at Mission Control in Houston, kept especially busy during "this insane, interesting time".
Mission Control says the lost mirror poses no risk to either the spacewalk or station. It is at 3 inches by 5 inches, with the band at around one-tenth of a pound, Independent said.
Overall, Cassidy and his colleague Robert Behnken completed all planned work in its first joint spacewalk they replaced the battery in the solar station ISS.

The new batteries provide an improved and more efficient power capacity for operations.
This fantastic clip shows the astronaut dropping the object in real-time action. Half as many as from the old ones have been replaced. It is hard to work with since each battery is about a meter tall and wide, and weighs 400 pounds each.
Their spacewalks are expected to continue through July before Behnken returns to Earth in August aboard a SpaceX Dragon capsule.
Last May, Doug Hurley and Behnken made history as the first astronaut launch by the latest space mission.
Friday's spacewalk was the seventh for both astronauts. The space walk lasted 6 hours and 7 minutes.
"Everything has to be cleaned and sanitized multiple times a day, so a special shoutout to the custodial staff at the Johnson Space Center", he said. Space station crew members have conducted 228 spacewalks in support of assembly and maintenance of the orbiting laboratory, according to NASA. "Thank you, Uncle Kirk".
