(AP Photo/NASA TV) Astronauts lubed a joint and wiped a solar panel clean today on the last spacewalk of the Endeavour mission, Space.com reports. The final repairs on the International Space Station took just over 6 hours but were cut short for astronaut Shane Kimbrough when carbon dioxide levels rose in his suit. Steve Bowen wrapped things up on the starboard-side job. "Finally!" he cried when the work was done. Before the walk started, NASA extended the 15-day Endeavour mission by one day to continue repairs on a wobbly urine recycler. All 10 astronauts will now be together for Thanksgiving. The shuttle is scheduled to leave on Friday and land on Sunday at about 1 pm Eastern Time. Read These Next White House isn't happy about the pick for the Nobel Peace Prize.
