The spacewalkers removed and replaced a Bearing Motor Roll Ring Module (BMRRM) that experienced electrical failures in early December. The BMRRM, or "broom", drives the solar arrays as they tilt towards the sun maximizing power generation.

WASHINGTON - NASA senior managers completed a review Wednesday of space shuttle Atlantis' readiness for flight. Pending closure of an issue with a shuttle radiator hose, the STS-122 mission will launch Feb. 7 at 2:45 p.m. EST.

During an inspection of Atlantis Tuesday, one of four hoses that carry Freon to the shuttle radiators in the payload bay was found bent and not properly retracted in its storage box. The others were fully retracted into their storage boxes, as expected. Teams are continuing to gather data and assess any potential forward work. Managers will convene Saturday to further review and analyze what, if any, remaining work is required before launch.
