Expedition
10 Spacewalks
The
Expedition 10 crew conducted two spacewalks during its stay at the International Space Station. The
spacewalks were devoted to ISS maintenance and assembly, with activities focusing
on the Zvezda Service Module.
The
primary objectives of the spacewalks were the installation of
an external workstation and research experiments and the preparation of the Station
for the arrival of the European Space Agency's unpiloted Automated Transfer Vehicle
(ATV).
Both spacewalks
were based out of the Pirs
Docking Compartment and used Russian Orlan spacesuits.

1 Salizhan Sharipov, Leroy Chiao Time: 5 hours, 28 minutes
Start time: 1:43 a.m. CST (0743 GMT) Jan. 26, 2005 End time: 7:11 a.m. CST
(1311 GMT) Jan. 26, 2005 After
they left Pirs, Sharipov and Chiao completed the installation of the Universal
Work Platform, along with its base and associated wiring. Then
they turned their attention to mounting the European commercial experiment Rokviss
(Robotic Components Verification on ISS). This experiment explores the use of
manipulator rotary joints operated from inside Zvezda via a receiver-transmitter.
Rokviss is designed to study remote operation of such joints and the effects of
space on them. Later,
the duo worked together to relocate the Japanese Microparticle and Capture &
Space Environment Exposure Device experiment to a new location on its rail-like
mounting. That experiment exposes various materials to space. At the old location
they installed a Rokviss antenna, then ran and connected cables to link a transceiver
with the experiment and the antenna. An
extra hour was added to the spacewalk to allow Sharipov and Chiao to check vents
on systems that help control the Station’s atmosphere and install a scientific
experiment. Before re-entering the Pirs Docking Compartment, the spacewalkers
installed the Russian Biorisk experiment, which is studying the impact of spaceflight
on microorganisms. Spacewalk
2 Salizhan Sharipov, Leroy Chiao Time: 4 hours, 30 minutes
Start time: 12:25 a.m. CST (0625 GMT) March 28, 2005 End time: 4:55 a.m. CST
(1055 GMT) March 28, 2005 Sharipov
and Chiao installed navigational and communications equipment for the arrival
of the first Automated Transfer Vehicle cargo craft. Sharipov also deployed an
11-pound Russian Nanosatellite expected to help develop small satellite control
techniques, monitor satellite operations and develop new attitude system sensors. |
