CAPE CANAVERAL, Fla. - Two spacewalking astronauts attached 11-foot arms to the international space station's huge new robot on Sunday, preparing the giant machine for its handyman job on the orbital outpost. With Dextre the robot's power problem solved, astronauts ventured outside the international space station on Saturday to put together the bulk of the gigantic walking and working machine. First, though, the robot was going to sit up on its transport bed, rising like Frankenstein as one astronaut put it. HOUSTON - With power now flowing to the international space station's new robot, the astronauts aboard the linked shuttle-station complex started preparing Saturday for a spacewalk to assemble the giant machine. Veteran astronaut Richard Linnehan and rookie partner Michael Foreman left the station's airlock just after 8 p.m. EDT (0000 GMT) to begin the second of five spacewalks planned during the shuttle Endeavour's 16-day spaceflight. The shuttle arrived at the orbital outpost on Wednesday for a 12-day construction and maintenance mission, the second of five visits to the space station NASA plans this year. Flight controllers breathed a big sigh of relief when the robot powered up after being hooked up to the international space station's robotic arm.
