HOUSTON - Expedition 14 Commander Michael Lopez-Alegria and Flight
Engineer Mikhail Tyurin retracted a stuck antenna on a cargo spacecraft
during a 6-hour, 18-minute spacewalk that ended at 10:45 a.m. CST Thursday.
On Oct. 26, the antenna failed to retract when the Progress vehicle
docked to the station's Zvezda Service Module. Moving the antenna was
necessary to ensure it would not interfere with the Progress undocking
Lopez-Alegria and Tyurin had planned to release the antenna latch with a
punch and a hammer. When clearance issues prevented that, they cut
struts supporting the antenna. That enabled them to partly retract the
antenna and secure it with wire ties. They reported it had about six
inches of clearance from Zvezda, adequate for undocking.
Early in the spacewalk, Tyurin had problems with his spacesuit's cooling
system, which caused his visor to fog up. But he and Lopez-Alegria were
able to complete a number of other tasks. They began the spacewalk by
photographing a Russian satellite navigation antenna and changing out a
Russian materials experiment. They also inspected and photographed an
antenna for the Automated Transfer Vehicle (ATV). The European cargo
craft has more capacity than the Progress and is scheduled to make its
first trip to the station later this year. The spacewalkers also
photographed ATV docking targets.
They photographed a German robotics experiment, inspected, remated and
photographed hardware connectors and inspected retention mechanisms and
bolted joints on a hand-operated Strela crane that helps transport
people and equipment outside Pirs. They also stowed two foot restraints
on a ladder at Pirs before ending the spacewalk.
The spacewalk from the Pirs docking compartment was conducted in Russian
Orlan spacesuits. It was the 81st for station assembly and maintenance,
the 53rd from the station, the 20th from Pirs and the fifth for this
station crew. This was the 10th spacewalk for Lopez-Alegria, a U.S.
record, and the fifth for Tyurin.
