Three spacewalks down. One to go.
Astronauts Stephen Bowen and Robert "Shane" Kimbrough venture outside the international space station Monday for the fourth and final spacewalk of space shuttle Endeavour's nearly two-week visit to the orbiting outpost.
The spacewalkers hope to finish unjamming a huge joint that keeps a power-generating solar wing on the space station's right side facing the sun. The joint hasn't been used much since September 2007 because parts were grinding, shaving off metal shards that jammed it and kept it from rotating toward sunlight. That limited the amount of energy the wing could produce.
Space station commander Michael Fincke said power generated by the wing will help the outpost's crew expand from three to six residents next year and allow more research 220 miles (354 kilometers) above Earth.
"We're going to need every watt of that power," Fincke said Sunday.
