WASHINGTON, Nov. 22 (Xinhua) -- Two U.S. astronauts on space shuttle Endeavour finished the third and longest spacewalk of the mission on Saturday, nearly wrapping up the lube job on the right-side solar panel joint outside the International Space Station, according to NASA TV.
Spacewalker Heidemarie Stefanyshyn-Piper and Steve Bowen reentered the Quest airlock at 7:58 p.m. (0058 GMT on Sunday). Their excursion was completely devoted to additional cleaning, lubricating and bearing-replacement of the massive, jammed joint.
