Two U.S. astronauts and a Russian cosmonaut, all spaceflight veterans, launched from Kazakhstan aboard a Soyuz booster Wednesday to begin a two-day pursuit of the International Space Station. The crew docked with the orbiting research complex Friday at 1940 GMT (3:40 p.m. EDT) to begin a five-month stay.
