Astronaut says losing mirror on spacewalk was 'real bummer'

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. “I just happened to glance down and I saw this reflecting thing disappearing into the darkness, and that was the last I saw of it,” Cassidy said in an interview with The Associated Press.
