Astronauts step outside space station for lube job

Two astronauts are out on a spacewalk for an unprecedented cleaning and lube job at the international space station.

Astronauts Heidemarie Stefanyshyn-Piper (stef-uh-NIHshun PIE-pur) and Stephen Bowen stepped outside the space station early Tuesday afternoon. It is the first of 4 spacewalks planned for the shuttle Endeavour's visit to the space station.

The astronauts are lugging grease guns, putty knives and oven-like mitts to try to remove metal grit from a gummed-up joint.

For more than a year, the joint has been unable to automatically point solar wings toward the sun for maximum energy production. The repair work will take up much of all four spacewalks.
