Astronaut who lost tool bag prepares for new space walk

The astronaut who lost her tool bag on a spacewalk admitted that she made a mistake by not checking to see if the sack was tied down, and said she’s still embarrassed over the whole thing.

Heidemarie Stefanyshyn-Piper said it was “very disheartening” to lose her bag full of tools. She was trying to clean up grease that had oozed out of a grease gun in the backpack-size bag, when it and everything in it floated away on Tuesday.
