　　The retired U.S. space shuttle Discovery is on its final voyage to a Washington-area aviation museum. The 28-year-old orbiter departed the Kennedy Space Center in Florida Tuesday, hitching a ride on the back of one of the U.S. space agency NASA's specially outfitted Boeing 747 jumbo jets. The shuttle is being flown over a variety of landmarks in the Washington area to give people the chance to see it. Discovery will land at Dulles International Airport in northern Virginia and be taken to the Udvar-Hazy Center, part of the Smithsonian's National Air and Space Museum.
        　　It was a little more than a year ago that Discovery lifted off from the Kennedy Space Center on its final mission. NASA retired the shuttle fleet last year to focus on developing the next generation of spacecraft that will travel beyond low earth orbit. On April 19, Discovery will be unveiled as part of the collection at the Udvar-Hazy Center, just outside Washington. Some of Discovery's famous former passengers will be in attendance, including astronaut John Glenn -- who in 1962 was the first American to orbit the Earth. He returned to space on Discovery in 1998.
