INTERNATIONAL SPACE STATION STATUS REPORT: SS07-33
HOUSTON - Expedition 15 Commander Fyodor Yurchikhin and Flight
Engineer Clay Anderson this week finished preparing their spacesuits
for a planned July 23 spacewalk. Yurchikhin and Flight Engineer Oleg
Kotov also continued evaluating the computers on the Russian segment
of the International Space Station.
During the U.S. spacewalk, Yurchikhin and Anderson will jettison a
support post for an exterior video camera and a 1,400-pound,
refrigerator-sized tank that is no longer needed. The tank, known as
the Early Ammonia Servicer, was designed to replenish ammonia to the
temporary cooling system on the station in the event of a coolant
leak.
The spacewalkers also will replace a faulty Remote Power Control
Module to restore backup power to the station's Mobile Transporter
railcar, which is needed for the space shuttle STS-118 mission. Other
tasks include cleaning the Unity node's nadir Common Berthing
Mechanism seals for the relocation of Pressurized Mating Adapter-3.
PMA-3 must be moved before the station's Harmony node arrives on
shuttle mission STS-120, which is targeted for late October.
Yurchikhin and Kotov worked on the Russian computers during the past
week, visually inspecting and photographing cables and connectors on
the command processing unit. Although there is no conclusive evidence
of what caused the problems during shuttle Atlantis' visit last
month, the inspections did yield some valuable information. The
voltage readings on cables and connectors for the secondary power
system appeared normal with the exception of one relay. Also, some
corrosion was found on a second connector and a third was discolored.
Troubleshooting continues.
In addition, the crew and flight controllers completed software
upgrades this week for computers on the U.S. and Russian segments.
The upgrades to the U.S. computers will allow the addition of the
Harmony node, the European Space Agency's Columbus module and the
Japanese Kibo Experiment Module during upcoming shuttle flights.
Plans are proceeding for the launch of the next Russian cargo ship,
the ISS Progress 26, which will deliver to the station new computers,
equipment, food, fuel, water and other supplies. Launch is scheduled
for Aug. 2, with docking planned on Aug. 5.
Also this week, Anderson discussed the progress of his mission and
life aboard the station during an educational in-flight event with
students at the Clay Center for Arts and Sciences in Charleston,
W.Va.
