STS-118 crew members will prepare for future International Space Station
assembly when they conduct the mission’s third spacewalk. The excursion,
scheduled to begin at 11:01 a.m. EDT(1501 UTC), will be conducted by
STS-118 Mission Specialist Rick Mastracchio and Expedition 15 Flight
Engineer Clay Anderson.
The spacewalking duo will prepare the Port 6 (P6) truss and its solar
arrays for relocation from atop of the station to the end of the Port 5
truss when STS-120 visits later this year. Their tasks include the
relocation of an antenna from the P6 to the Port 1 (P1) truss, retrieval
a transponder for return to Earth and the relocation of two rail carts
on the station’s Integrated Truss Structure. They will install a new
transponder on the P1, which along with the relocated antenna will
upgrade the station’s communications capability.
Mastracchio and Anderson will also retrieve two material experiments
from the station’s exterior. The experiments will be analyzed by
scientists on Earth.
Today’s spacewalk will be 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 will resume her role as STS-118’s
spacewalk coordinator and Pilot Charles Hobaugh will be at the controls
of the station’s robotic arm.
The spacewalk is slated to last 6.5 hours.
*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.
