CAPE CANAVERAL, Fla. – NASA astronaut candidates survey Launch Complex 34 at Cape Canaveral Air Force Station in Florida, adjacent to NASA's Kennedy Space Center. Complex 34 was the sight of NASA's first astronaut fatalities when the crew of Apollo 1, Gus Grissom, Ed White and Roger Chaffee, died in a fire inside their Apollo capsule during testing at the pad. The astronaut class of 2013 was selected by NASA after an extensive year-and-a-half search. The new group will help the agency push the boundaries of exploration and travel to new destinations in the solar system.
