Report #36 
9:30 a.m. CDT, Friday, August 16, 2002 
Mission Control Center, Houston, Texas 

Expedition Five Commander Valery Korzun and Flight Engineer Peggy Whitson
stepped outside the Pirs Docking Compartment of the International Space
Station today and installed debris shields on the Russian Zvezda Service
Module in a 4 hour, 25 minute spacewalk.

It was the first of two spacewalks for the Expedition Five crew, the
third of Korzun’s career and the first for Whitson. Today’s excursion was
the 42nd spacewalk in support of ISS assembly and maintenance and the
17th staged from the station itself. 25 spacewalks at the ISS have
originated from visiting space shuttles. While Korzun and Whitson worked
outside, Flight Engineer Sergei Treschev tended to station systems and
choreographed the spacewalk from inside Zvezda.

After a 1 hour, 43 minute delay to the start of the spacewalk because of
a misconfigured valve regulating the operation of the primary oxygen
bottles in their Orlan spacesuits, Korzun and Whitson opened the hatch to
Pirs at 4:23 a.m. Central time (923 GMT) as the ISS flew over the
southern Atlantic Ocean east of the southern coast of South America at an
altitude of 230 statute miles. Their first task was to set up tools and
unfurl a telescoping crane called the Strela boom from the side of the
docking module that is attached to the nadir port of Zvezda.

They pressed ahead to move six micrometeoroid debris shields from a
temporary stowage location on the connecting module adapter between the
U.S. and Russian segments of the ISS that were delivered in June during
the STS-111 mission of the shuttle Endeavour.

One by one, the shields were affixed around Zvezda, designed to provide
debris protection for the lifetime of the module. 17 additional shields
will be flown to the ISS on future missions to complete the job.

Because of the late start to the spacewalk, Russian flight controllers
decided to defer the refurbishment of an experiment on Zvezda called
Kromka, designed to collect samples of residue emitted from the module’s
jet thrusters. That lower priority task and the swabbing of thruster
residue from Zvezda’s hull for analysis will be conducted on a future
spacewalk. It was not immediately known whether Korzun and Treschev would
perform those tasks next Friday during the second spacewalk of the

After retrieving their tools and stowing the Strela crane, Korzun and
Whitson returned to Pirs and closed the hatch at 8:48 a.m. Central time
(1348 GMT) to wrap up their excursion.

Korzun will venture outside Pirs one week from today with Treschev to
install equipment on the exterior of the Russian module which will
facilitate the placement of future payloads and the routing of
spacewalkers’ tethers and to replace Japanese experiments outside Zvezda
which measure the effect of atomic oxygen in low Earth orbit on sample
materials. Korzun and Treschev will also install two additional amateur
radio antennas outside Zvezda to improve contacts with ham radio
operators on Earth.

launch dates, as well as station sighting opportunities from anywhere on

next station spacewalk, or sooner, if events warrant.
