The Expedition
Four crew has conducted three spacewalks during its stay onboard
the International Space Station. The crew has spent a total of
17 hours and 49 minutes outside the station. Thirty-four spacewalks
-- nine station-based and 25 shuttle-based -- have been conducted
at the station for total of 208 hours and 5 minutes.

Spacewalk
1
Yury Onufrienko, Carl Walz
Actual time: 6 hours, 3 minutes
Start time: 2:59 p.m. CST (2059 GMT) Jan. 14, 2002
End time: 9:02 p.m. CST Jan. 14, 2002 (0302 GMT Jan. 15, 2002)
Onufrienko
and Walz relocated the cargo boom for the Russian Strela crane.
They moved the boom from Pressurized Mating Adapter 1 to the exterior
of the Pirs Docking Compartment. The crew also installed an amateur
radio antenna onto the end of the Zvezda Service Module. The space
walk was based out of Pirs and used Russian Orlan spacesuits.

videos show the locations of equipment moved during the spacewalk.
Spacewalk
2
Yury Onufrienko, Daniel Bursch
Time: 5 hours, 59 minutes
Start time: 9:19 a.m. CST (1519 GMT) Jan. 25, 2002
End time: 3:18 p.m. CST (2118 GMT) Jan. 25, 2002
During Expedition
Four's second spacewalk, Onufrienko and Bursch installed six deflector
shields for the Zvezda Service Module's jet thrusters. Also, they
installed an amateur radio antenna, attached four science experiments,
and retrieved and replaced a device to measure material from the
thrusters. Like the first EVA, this one was based out of Pirs,
and the spacewalkers used Orlan suits.
Spacewalk
3
Carl Walz, Daniel Bursch
Time: 5 hours, 49 minutes
Start time: 5:38 a.m. CST (1138 GMT) Feb. 20
End time: 11:25 a.m. CST (1725 GMT) Feb. 20
This spacewalk
was based out of the Quest Airlock, using U.S. spacesuits. Walz
and Bursch tested the airlock and prepared for the four spacewalks
that will be performed during STS-110 in April. The STS-110 crew
will install the S0 Truss onto the station. This spacewalk was
the first spacewalk to be based out of Quest without a space shuttle
at the station. |
