FILE - In this Oct. 29, 1998 photo, Sen. John Glenn, D-Ohio, waves as he leaves the Operations and Checkout Building at Kennedy Space Center. Glenn, Commander Curt Brown, front, and five other crew members were on their way to Launch Pad 39-B and a planned liftoff on the Space Shuttle Discovery. The world’s most traveled spaceship took its last flight on Tuesday, April 17, 2012. Riding on the back of a 747 jet, Discovery traveled from Cape Canaveral, Fla., to Chantilly, Va. The space shuttle will be installed this week in its new home, the Smithsonian’s National Air and Space Museum annex near Dulles in Northern Virginia. (AP Photo/Chris O'Meara) less
