The STS-118 crew continued the on-orbit construction of the
International Space Station with the addition of the Starboard 5 (S5)
truss segment. With spacewalkers Rick Mastracchio and Dave Williams
assisting, Pilot Charles Hobaugh used the station’s robotic arm to
attach the S5 about 1:35 p.m. EDT.
The spacewalkers are now focusing on the completion of the installation
by bolting the S5 in place on the end of the Starboard 4 truss segment
and making power and data connections.
The next major task of the spacewalk is the retraction of a radiator on
the Port 6 (P6) truss. After the radiator is folded, Mastracchio and
Williams will secure it. The P6 will be relocated from atop the station
to the end of the Port 5 truss during a future shuttle mission.
Mastracchio and Williams kicked off STS-118’s first spacewalk at 12:28
p.m. EDT and are scheduled to wrap up at about 6:58 p.m. STS-118 Mission
Specialist Tracy Caldwell is the spacewalk coordinator, and Expedition
15 Flight Engineer Clay Anderson is assisting Hobaugh at the controls of
the station’s Canadian-built robotic arm.
The Station-to-Shuttle Power Transfer System, which was activated after
Friday’s docking, has been shut down as a precaution during the
spacewalk. It will be brought back online after the conclusion of the
excursion. The transfer system may allow Space Shuttle Endeavour and the
STS-118 crew to stay at the station longer. A decision on a possible
mission extension to 14 days is expected to be made Sunday.
