NASA TV to Cover Next Expedition Four Spacewalk

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 operations.

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 choreographer.

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.

NASA TV is available on GE-2, Transponder 9C at 85 degrees West longitude, vertical polarization, with a frequency of 3880 MHz, and audio of 6.8 MHz. Additional information on the International Space Station and the Expedition Four crew is available on the Internet at:
