Astronauts Rick Mastracchio and Clay Anderson are rolling through their
scheduled activities as they work outside the International Space Station.
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.
Before the excursion ends, Mastracchio and Anderson will retrieve two
materials science experiments from the station’s exterior. The
experiments were deployed in August 2006 and will be returned to Earth
for analysis. Since the spacewalkers are ahead of the timeline, flight
controllers may give them approval to tackle some get-ahead tasks.
Today’s spacewalk is 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.
The spacewalk is slated to end at 5:07 p.m.
*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.
