Two American astronauts are stepping through a spacewalk outside linked shuttle Discovery and the International Space Station, doing prep work in advance of a remote-control radiator deployment slated to take place later today.
Discovery mission specialist Scott Parazynski is setting up handrails outside the new U.S. Harmony module, which was hauled up to the station aboard the shuttle. The handrails will enable future spacewalking assembly and maintenance crews to crawl around the cylindrical module.
Station flight engineer Dan Tani, who flew up to the station aboard Discovery, is working on the starboard side of the station's central truss, reconfiguring connectors so a heat-dissipating radiator can be deployed later today. The 40-foot radiator is located on the S1 truss segment.
Tani also aims to replace a faulty circuit breaker inside the lattice-like truss.
