NASA's Orion spacecraft is off loaded from the back of USS Anchorage at Naval Base San Diego, California December 8, 2014. Orion splashed down in the Pacific Ocean approximately 600 miles southwest of San Diego after completing a two-orbit, 4.5 hour flight test that took it farther into space than any spacecraft built for humans has been in more than 40 years.
