-- Exchange crew members. Sandra Magnus will swap places with current station resident Greg Chamitoff.

-- Conduct four spacewalks. Working in teams of two, astronauts will emerge from the space station’s Quest airlock and work on the two large joints that turn the station’s massive solar array “wings.” They are to service the starboard side joint and perform preventative maintenance on the port side joint.

-- Install new crew quarters, a galley, waste water recycling system and oxygen generator inside the space station. The equipment has been packed inside refrigerator-sized racks that require forklifts to lift them on Earth. But in space, a single astronaut can move a rack around with little problem.

Endeavour and its crew are to land at NASA’s Kennedy Space Center after 15 days in space.
