CAPE CANAVERAL, Fla. – Space shuttle Discovery, mounted to a Shuttle Carrier Aircraft, or SCA, takes off from NASA Kennedy Space Center’s Shuttle Landing Facility runway 15 in Florida at 7 a.m. EDT. The duo is beginning its ferry flight to the Washington Dulles International Airport in Virginia that also includes a flyby of the Space Coast and Washington, D.C. Discovery is leaving Kennedy after more than 28 years of service beginning with its arrival on the space coast Nov. 9, 1983. Discovery first launched to space Aug. 30, 1984, on the STS-41D mission. Discovery is the agency’s most-flown shuttle with 39 missions, more than 148 million miles and a total of one year in space. Discovery is set to move to the Smithsonian’s National Air and Space Museum, Steven F. Udvar-Hazy Center in Chantilly, Va., on April 19 where it will be place on public display.
