Second EVA success; water recycling glitch studied
Despite a tool shortage, a spacesuit carbon dioxide buildup late in the day and communications problems, spacewalkers Heidemarie Stefanyshyn-Piper and Shane Kimbrough accomplished their primary goals, officials said Thursday, moving two equipment carts, servicing the station's robot arm and continuing work to clean and lubricate a jammed solar array rotary joint. Inside the lab complex, meanwhile, other astronauts ran into start-up glitches with the new urine processor.

Spacewalker expresses remorse for lost tool bag
Astronaut Heidemarie Stefanyshyn-Piper told reporters Wednesday the loss of a $100,000 tool bag during an otherwise successful spacewalk Tuesday was "disheartening" and that it was difficult to face her crewmates when she returned to the shuttle-space station complex. Fellow spacewalker Stephen Bowen, who said he was responsible for making a final tether check of the bag before the EVA began, said he was equally to blame for the mishap.
