*Spacewalk Ends Early; Major Tasks Completed*
Flight controllers decided just before 3 p.m. EDT to end today’s
spacewalk early because of damage to the outer layer of one of Mission
Specialist Rick Mastracchio’s gloves. Even though there is no threat to
his safety, the decision was made as a precaution.
His spacewalking partner, Clay Anderson, is finishing with the retrieval
of a transponder on the Port 6 truss. Mastracchio will remain in the
Quest airlock until Anderson returns to the airlock following finishing
Retrieval of the two MISSE experiments will be deferred to a future
spacewalk. The experiments were deployed in August 2006 and will be
returned to Earth for analysis.
Mastracchio and Anderson have completed most of the scheduled spacewalk
activities. They continued preparations for the relocation of the Port 6
(P6) truss and its solar arrays by moving two Crew Equipment Translation
Aid carts along the Integrated Truss Structure rail system. This will
allow the station’s arm to perform the P6 relocation work during
STS-120. The P6 will be moved from atop the station to the end of the
Port 5 truss.
Early in the spacewalk, the duo relocated an antenna from the Port 6
(P6) to the Port 1 (P1) truss. In addition to the antenna relocation,
the spacewalkers installed a new transponder and signal processor in an
S-band communications system upgrade.
Today’s spacewalk was Mastracchio’s third of the mission. Anderson, who
arrived at the station in June, conducted his first spacewalk on July 23
with Expedition 15 Commander Fyodor Yurchikhin.
Mission Specialist Tracy Caldwell is the spacewalk coordinator, and
Pilot Charles Hobaugh is at the controls of the station’s robotic arm.
*Mission Management Team Update*
Mission managers have determined that damage to a small section of
Endeavour’s heat shield poses no threat to crew safety or mission
operations. However, they are discussing options for possible repair
work that would ensure preparations on the ground for Endeavour’s next
flight will go more smoothly. The damage occurred during the climb to
orbit on Aug. 8.
