CAPE CANAVERAL, Fla. -- At the Kennedy Space Center in Florida, NASA administrator Charles Bolden, at right, enjoys an unobstructed view of the flame trench on Launch Pad 39B with Apollo astronauts and their families and friends. The pad is being modified to support the agency's new Orion spacecraft which will lift off atop the Space Launch System rocket. Orion is designed to take humans farther than they’ve ever gone before, serving as the exploration vehicle that will carry astronauts to deep space and sustain the crew during travel to destinations such as an asteroid or Mars. The visit of the former astronauts was part of NASA's 45th anniversary celebration of the Apollo 11 moon landing. As the world watched, the Apollo 11 astronauts landed in the moon's Sea of Tranquility aboard the lunar module Eagle on July 20, 1969.
