The second spacewalk by members of the Expedition Four
crew aboard the International Space Station will be covered on
NASA Television beginning at 10 a.m. EST Friday, Jan. 25.

Commander Yury Onufrienko and Flight Engineer Dan Bursch will
exit the Pirs Docking Compartment around 10:35 a.m. EST for a
six-hour spacewalk to install protective covers around
thrusters on the Russian Zvezda Service Module. The crew will
also attach additional antennas for future amateur radio

Flight Engineer Carl Walz, who conducted a spacewalk with
Onufrienko last week, will operate the space station’s robotic
arm – Canadarm2 – from inside and will serve as spacewalk

One more spacewalk is planned during the five-month Expedition
Four mission when Walz and Bursch will exit the U.S. Airlock
Quest next month to preposition equipment that will be used
during the installation of the S0 (S Zero) Truss on the ISS in
April by the STS-110 crew.
