6:30 a.m. CDT, Monday, August 26, 2002 
Mission Control Center, Houston, Texas 

Expedition Five Commander Valery Korzun and Flight Engineer Sergei
Treschev stepped outside the Pirs Docking Compartment of the
International Space Station today to swap out Japanese space exposure
experiments and a Russian experiment measuring jet thruster residue on
the exterior of the Zvezda Service Module in a 5 hour, 21 minute
spacewalk.

It was the second of two spacewalks for the Expedition Five crew, the
fourth of Korzun’s career and the first for Treschev. Today’s excursion
was the 43rd spacewalk in support of ISS assembly and maintenance and the
18th staged from the station itself. 25 spacewalks at the ISS have
originated from visiting space shuttles. While Korzun and Treschev worked
outside, Flight Engineer Peggy Whitson tended to station systems and
choreographed the spacewalk from inside Zvezda.

Whitson and Korzun conducted a 4 hour, 25 minute spacewalk on August 16
to install six micrometeoroid debris shields on Zvezda.

After a slight delay to track down a small pressure leak across the hatch
between Zvezda and the Zarya module, Korzun and Treschev opened the hatch
to Pirs at 12:27 a.m. Central time (527 GMT) as the ISS flew over Russia
at an altitude of 235 statute miles. They went to work right away,
installing a frame on the Zarya as a “parking place” for modular
equipment to be temporarily stowed during future ISS assembly spacewalks
and hardware on Zarya which will better route tethers for spacewalkers
working around the Russian segment of the station.

The two Russian spacewalkers then exchanged trays of experiments in
suitcase-like devices on Zvezda for NASDA, the Japanese Space Agency,
which measure the effect of the space environment on engineering
materials.

With that work accomplished, Korzun and Treschev completed a task left
over from the previous spacewalk ten days ago. They replaced an
experiment on the outside of Zvezda called Kromka, which measures the
amount of residue emitted from the module’s jet thruster firings.
Deflectors previously installed on Zvezda have significantly reduced the
buildup of residue on the hull of the module.

The final job for Korzun and Treschev was the installation of two
additional ham radio antennas on Zvezda to enhance amateur radio
operations in the future. ISS residents frequently conduct conversations
with “hams” back on Earth.

After retrieving their tools, Korzun and Treschev returned to Pirs and
closed the hatch at 5:48 a.m. Central time (1048 GMT) to wrap up their
excursion.

The next series of spacewalks to be conducted at the ISS is planned for
October when two shuttle astronauts, Dave Wolf and Piers Sellers, conduct
three excursions from the Quest Airlock on the STS-112 mission aboard
Atlantis to help install and activate the S1 (Starboard One) truss
segment, further expanding the station’s backbone.

Information on the crew's activities aboard the space station, future
launch dates, as well as station sighting opportunities from anywhere on
the Earth, is available on the Internet at:

Details on station science operations can be found on an Internet site
administered by the Payload Operations Center at NASA's Marshall Space
Flight Center in Huntsville, Ala., at:

The next ISS status report will be issued on Friday, Aug. 30, or sooner,
if events warrant.
