Spacewalking astronauts performed more repair work on a jammed joint at the International Space Station today, keeping a tight grip on all their tools so nothing would get away this time. The spacewalk—the second of four planned for shuttle Endeavour's visit— went smoothly and fell on the 10th anniversary of the space station.
During the mission's first spacewalk on Tuesday, a $100,000 tool bag slipped away. Today, however, Heidemarie Stefanyshyn-Piper and Shane Kimbrough deftly stepped through their work without any mishaps. The primary job 220 miles up was to clean and lubricate the massive joint that controls the solar wings on the right side of the space station, and to replace its bearings.
