Astronaut Loses Tools While Performing an EVA

tpheiska writes "NASA press release states that 'At approx. 3:33 p.m. EST, Piper reported that one of the Braycote lubrication guns had released grease into her toolbag. As she was cleaning the bag and wiping the tools and equipment inside, the bag floated away. Another bag carrying identical equipment is now being shared by Piper and Bowen.' Luckily they had a spare."

STS-126 Crew Completes First Spacewalk; Lose a Tool Bag

The first STS-126 spacewalk ended at 8:01 PM EST last night. STS-126 mission specialists Heide Stefanyshyn-Piper and Steve Bowen worked outside the station Tuesday for the first of the mission's four spacewalks. Spending six hours and 52 minutes outside the station, the pair worked on several tasks including removing a depleted nitrogen tank from a stowage platform and moving it into Endeavour's cargo bay then replaving it. They also moved a flex hose rotary coupler from the shuttle to the station stowage platform, as well as removing some insulation blankets from the common berthing mechanism on the Kibo laboratory. Another task included the start of cleaning and lubrication of the starboard solar alpha rotary joint.
