The astronaut who recently 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 smarting over the whole thing.
Heidemarie Stefanyshyn-Piper said in an interview with The Associated Press 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 the tote and everything in it floated away.
The bag was one of the largest items ever lost by a spacewalking astronaut. NASA put the price tag of the tool bag at $100,000.
