EVA tool bag lost by space shuttle Endeavour astronaut Heidemarie Stefanyshyn-Piper on 18 November 2008 during a space walk to repair the International Space Station. She lost hold of the 14-kg bag (which NASA estimates cost about £66,000) after attempting to clean it out after a grease gun she was carrying to lubricate joints on the station had leaked in it. The bag slipped away from her without damaging the spacecraft and drifted off into space. The bag orbited the Earth for a year and was briefly visible through amateur-sized telescopes before it burned up over the Pacific Ocean just west of Mexico. It is one of the largest items lost on a space walk.
