NASA astronauts Butch Wilmore and Suni Williams returned to Earth on Tuesday, hitching a different ride home to close out a saga that began with a bungled test flight more than nine months ago. Their SpaceX capsule parachuted into the Gulf in the early evening, just hours after departing the International Space Station. Splashdown occurred off the coast of Tallahassee in the Florida Panhandle, bringing their unplanned odyssey to an end. The astronauts were being flown from Tallahassee to Houston Tuesday night.
