Another ISS spacewalk is completed

HOUSTON, Feb. 5 (UPI) -- International Space Station astronauts conducted their second spacewalk in four days Sunday, with astronaut Suni Williams setting a record.

Expedition 14 Commander Mike Lopez-Alegria and Williams began their seven-hour spacewalk at 8:38 a.m. EST, a few minutes ahead of schedule. After setting up tools and tethers, they rerouted a series of electrical cables and other lines from the soon-to-be defunct Early External Active Thermal Control System to a permanent cooling system.

NASA said they also assisted in the retraction of the space station's aft heat-rejecting radiator that had been used since 2000 to keep station systems at the correct temperature through the temporary cooling system.

Once the radiator was retracted, Lopez-Alegria and Williams completed Wednesday's unfinished task of disconnecting the second of two fluid lines for the Early Ammonia Servicer -- a unit that's no longer needed.

Williams now holds the record for most spacewalking time by a female. Former astronaut Kathy Thornton previously held that honor.

National Aeronautics and Space Administration controllers in Houston said Lopez-Alegria and Williams will spend Monday preparing their spacesuits and tools for their third spacewalk in nine days, set for Thursday.
