NASA's Orion spacecraft on Friday successfully completed its first test flight, splashing down in the Pacific Ocean west of Baja California at 8:29 a.m. PST after orbiting the Earth twice in roughly four and a half hours. Orion traveled some 60,000 miles during the mission and journeyed 3,600 miles into space -- 15 times more distant than the International Space Station and farther than any ship designed to carry humans has gone in more than 40 years. The mission is a critical step in NASA's journey to Mars.
