> STATUS REPORT: SS07-07
> INTERNATIONAL SPACE STATION STATUS REPORT: SS07-07
> 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
> 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
> 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.
