ISS crew conducts spacewalk
Posted: Sat, Jan 26, 2002, 11:05 AM ET (1605 GMT)
ISS spacewalk by Onufrienko and Walz (NASA) Two members of the International Space Station's Expedition Four crew successfully conducted the second spacewalk in as many weeks outside the station Friday. Cosmonaut Yuri Onufrienko and astronaut Daniel Bursch spent six hours outside the station Friday, starting at 10:19 am EST (1519 GMT). The spacewalkers completed their primary task of installing plume deflectors around six attitude control thrusters on the Zvezda module. The deflectors are designed to contain the exhaust residue from the thrusters so that it does not contaminate other portions of the module or interfere with future EVAs. Onufrienko and Bursch later installed the second of four ham radio antennas on Zvezda; the first was installed by Onufrienko and Carl Walz during their spacewalk January 14. The two spacewalkers also attached several physics and material science experiments to the exterior of the station and retrieved one experiment, Kromka. They also attached "fairleads", or guides that will keep tethers of future spacewalkers from fouling equipment on the station's exterior. The spacewalk was the second by the Expedition Four crew, and the eighth conducted from the station.
