Not the first incident of space junk, that's for sure. Here's an amusing article from the AP. A spacewalking astronaut has had a grease gun erupt in her bag, and the tote has drifted off into space. Heidemarie Stefanyshyn-Piper (stef-uh-NIHshun PIE-pur) was wiping the grease off her spacesuit Tuesday when she accidentally let go of the bag outside the international space station. The bag floated off, and the astronauts were not able to do anything about it. She was on the spacewalk with Stephen Bowen. He had his own tool bag with another grease gun, putty knife and oven-like terry cloth mitts. They are using those tools to wipe away metal grit from a clogged joint at the space station. Mission Control says the spacewalk will continue as planned, and that the two astronauts will share tools.
This reminds me of a camera an astronaut lost in space:
