Two veteran cosmonauts sailed through a six-hour spacewalk outside the International Space Station yesterday to prepare the orbital outpost for a new module and better shield its living quarters against small meteorite and debris impacts, officials said.<\/p>\n
Stationcommander Gennady Padalka and flight engineer Yuri Malenchenko opened the hatch on thestation's airlock at 11:37 am EDT (1537 GMT) to begin aspacewalk to relocate a construction crane, install debris shields and release a small satellite into orbit. <\/p>\n
Their departure was delayed about an hour while engineers assessed a leak between the Pirs docking module and Russian segments of thestation, a $100 billion laboratory for microgravity experiments and technology testing that flies about 250 miles (400 km) above Earth. <\/p>\n
But the issue was resolved and the experiencedspacewalkers more than made up the lost time. <\/p>\n
Padalka, who was making his ninthspacewalk, and Malenchenko, on his fifth, moved a hand-operated, 46-foot (14-meter) crane, called Strela-2, from the outside of Pirs to Zarya, the cornerstone of thestation. Pirs is due to be detached from thestationnext year to make room for a new Russian laboratory and docking module. <\/p>\n
The United States completed construction of its part of the outpost last year and retired its threespaceshuttles. Europe, Japan and Canada also are partners on the project. <\/p>\n
With the crane in place, thespacewalkers then used a hand tool to launch a 20-pound (nine-kg) spherical satellite on a path behind thespacestation. <\/p>\n
\"Nice throw,\" a flight director in the Russian mission control center outside Moscow said through a translator monitoring radio communications with the cosmonauts. <\/p>\n
The satellite, which is expected to remain in orbit for about three months, is intended to serve as a target for Russian engineers working on computer models that evaluate orbital tracking. <\/p>\n
Thespacewalkers' last major task was to install five debris shields to the outside of the Zvezda module, the crew's primary living quarters. They also retrieved a briefcase-sized experiment that has been exposing various materials to the harsh environment ofspaceand installed two support struts on a ladder. <\/p>\n<\/p>\n
