*International Space Station Status Report #06-36*
*5 p.m. CDT, Thursday, Aug. 3, 2006*
*Expedition 13 Crew*
Space station crewmen Jeff Williams and Thomas Reiter worked quickly
through scheduled spacewalk tasks Thursday, then completed three
get-ahead jobs, or extra tasks, and were ready for more. Mission Control
assigned two more jobs, which the astronauts also completed.
Williams and Reiter wrapped up their productive 5-hour, 54-minute
excursion and began repressurizing the Quest airlock at 3:58 p.m. EDT.
The astronauts left the airlock in U.S. spacesuits at 9:04 a.m. EDT.
Station Commander Pavel Vinogradov helped them with spacewalk
preparations and getting into their suits. It was the first time in more
than three years a third crewmember had been available for those tasks
on the orbiting laboratory.
Williams, designated lead spacewalker, or EV1, wore the U.S. spacesuit
with red stripes. Reiter, EV2, wore the all-white suit.
Astronaut Steve Bowen acted as spacewalk intravehicular officer and
coached the astronauts from the International Space Station Flight
Control Room in Houston's Mission Control Center. Williams and Reiter
quickly got ahead of their timeline. First, they installed the Floating
Potential Measurement Unit. The device measures the electrical potential
of the station so procedures can be devised to minimize arcing hazards,
or the jumping of current from a conductor to a ground, as the station
grows.
Their second job was to install two MISSE containers, or Materials on
International Space Station Experiment. The suitcase-like containers are
left open to evaluate the long-term effects of space exposure on a
variety of materials. The idea is to identify optimal materials for use
in future spacecraft. MISSE 3 went on one of the high-pressure tanks
around the crew lock, while MISSE 4 was installed on Quest's outboard end.
The two astronauts then went on to separate jobs. Williams installed a
controller for a thermal radiator rotary joint on the S1 truss, while
Reiter replaced a computer on the truss.
Williams then began installing a starboard jumper and spool positioning
device (SPD) on the S1 truss. Reiter inspected a radiator beam valve
module SPD site where one device was already installed and installed an
additional one. He then moved on to install a SPD on a port cooling line
jumper. The jumpers are designed to improve the flow of ammonia through
the radiators once that coolant is installed.
Williams began setup for the final major scheduled task, a test of an
infrared camera designed to detect damage in a shuttle's reinforced
carbon carbon (RCC) thermal protection. The camera highlights damage by
showing variations in temperature between clean and damaged RCC test
sections. Reiter operated the experiment while Williams went on to one
of the additional tasks.
The first task was installation of a light to help future spacewalkers
on the truss railway handcart. Williams then removed a malfunctioning
GPS antenna. After Reiter finished the infrared camera experiment, he
installed a vacuum system valve on the U.S. laboratory Destiny for
future scientific experiments.
Mission control came up with additional tasks. Williams moved two
articulating portable foot restraints to prepare for STS-115 spacewalks
and then photographed a scratch on the airlock hatch. Reiter went to
PMA1, a pressurized "corridor", to retrieve and inspect a ball stack,
which holds hardware during spacewalks. The crew also had additional
time throughout the spacewalk to photograph the worksites after their
tasks were complete and then snap pictures of each other at the end.
With no more quick tasks to add, the spacewalkers re-entered the airlock
and closed the hatch early.
The next station status report will be issued on Friday, Aug. 11, or
earlier if events warrant. For more about the crew's activities and
