Skywalkers Continue Home Improvements in Space

Description: Building on the first spacewalk experience of STS-126, Heide Stefanyshyn-Piper and Shane Kimbrough headed out of the International Space Stations Quest Airlock at 11:58 a.m. CST to continue the process of removing debris around the starboard Solar Alpha Rotary Joint (SARJ) and applying lubrication in an effort to eventually restore it to full functionality. The EVA ended at 6:43 p.m. for a total time of six hours and 45 minutes. As the spacewalkers were finishing up their activities, ground controllers noticed that Kimbroughs carbon dioxide levels were increasing, so he made his way back to the airlock a few minutes ahead of Piper.
