CAPE CANAVERAL, Fla. (AP) — The commander of the International Space Station said Monday that losing a mirror during last week’s otherwise successful spacewalk was “a real bummer.”

NASA astronaut Chris Cassidy said he has no idea how the small mirror on his left sleeve came off. The band for the mirror is on pretty tight, he noted, and it may have caught on a metal tether attachment as he exited the airlock Friday.
