The crew of the international space station successfully moved a Russian space craft from one part of the orbiting station to another Tuesday in a maneuver designed to make upcoming space walks easier, a Russian spokeswoman said. Russian cosmonaut Sergei Krikalyov and U.S. astronaut John Phillips undocked the Soyuz TMA-6 space craft from the station's Pirs docking module at around 2:40 p.m. (1040 GMT), spokeswoman Vera Medvedkova. About 25 minutes later, the two re-docked the capsule with a Zarya cargo vessel, about 14 meters (45 feet) away, she was quoted as saying by The Associated Press.
