> HOUSTON - With all scheduled tasks accomplished, International Space 
> Station Commander Mike Lopez-Alegria and Flight Engineer Sunita 
> Williams ended a nearly seven hour spacewalk at 2:06 p.m. CST 
> Thursday. 
> It was the last in a series of three spacewalks in nine days from the 
> Quest airlock. Major tasks of this spacewalk included removing and 
> jettisoning two large shrouds and installing an attachment for cargo 
> carriers. 
> Lopez-Alegria and Williams moved from the airlock out to Crew 
> Equipment Transfer Aid carts on the rails of the main truss. Pushing 
> one cart with their equipment, including a foot restraint, they moved 
> to the Port 3 truss segment. Their first job was to remove two 
> thermal shrouds, one from each of two Rotary Joint Motor Controllers 
> on P3. 
> Next, they removed two large shrouds from P3 Bays 18 and 20. The 
> shrouds, larger than king-size bed sheets, provide thermal shading. 
> With the station in its present orientation, they are no longer 
> needed and are being removed to avoid trapping heat. Lopez-Alegria 
> jettisoned them toward the rear of the station. 
> Afterward, the Unpressurized Cargo Carrier Assembly Attachment Systems 
> on the upper face of the P3 truss was deployed. That was done in 
> preparation for attachment of a cargo carrier during a future shuttle 
> mission. While Lopez-Alegria finished work on the assembly attachment 
> system, Williams moved to the end of the P5 truss to remove two 
> launch locks in preparation for the relocation of the P6 truss. 
> The final scheduled task of the spacewalk was connecting four cables 
> of the Station to Shuttle Power Transfer System to Pressurized Mating 
> Adapter-2 (PMA-2) at the forward end of the Destiny laboratory where 
> shuttles dock. This will allow visiting shuttles to take power from 
> the station to extend their missions. 
> Work began on the system during the Jan. 31 spacewalk, and two of the 
> cables were routed and connected to PMA-2 on the Feb. 4 spacewalk. 
> The last four cables were connected to the PMA Thursday. The 
> astronauts did complete one get-ahead task to photograph a suspect 
> connector on the outboard end of PMA-2. It carries station shuttle 
> communications when the shuttle is docked but hatches are closed. 
> Communications have been intermittent during recent shuttle missions. 
> Throughout the spacewalk, Chris Looper in Johnson Space Center's 
> Mission Control advised Lopez-Alegria and Williams and monitored 
> their tasks. Looper is the chief engineer for the Astronaut Office 
> Spacewalk Branch. 
> Approximately 3 hours, 50 minutes into his ninth spacewalk, 
> Lopez-Alegria set a record for cumulative spacewalk time by a U.S. 
> astronaut at 61 hours, 22 minutes. Jerry Ross previously held the 
> title with 58 hours, 32-minutes accumulated during nine spacewalks. 
> The three spacewalks from the Quest airlock in U.S. spacesuits and a 
> Russian spacewalk on Feb. 22 are the most ever done by station crew 
> members during such a short period. Starting from scratch, it takes 
> crew members about 100 hours to prepare for a spacewalk. By doing the 
> U.S. spacewalks just a few days apart, considerable crew time can be 
> saved by not having to repeat some of the preparation. 
> Thursday's spacewalk was the 80th for station assembly and 
> maintenance. It was the 52nd from the station and the 32nd from 
> Quest. It was the fourth for Williams, the most for any woman. 
> During the Feb. 22 spacewalk, Lopez-Alegria and Flight Engineer 
> Mikhail Tyurin will wear Russian Orlan suits to work on an antenna on 
> the Progress 23 cargo ship docked at the aft port of the Zvezda 
> service module. The antenna did not properly retract when that 
> spacecraft docked in October. The spacewalkers will try to secure or 
> remove the antenna to avoid any interference with the undocking of a 
> Progress in April. The spacewalk will be the 10th for Lopez Alegria 
> and will set a new record.
