This week NASA's space shuttle Discovery will fly low over Washington, D.C., atop a jumbo jet and roll into its new permanent home with the Smithsonian Institution.

Discovery will touch down at Dulles International Airport on Tuesday, weather permitting, and the National Air and Space Museum's Steven F. Udvar-Hazy Center in Chantilly, Virginia, will host a big outdoor ceremony on Thursday to welcome their new space-worn acquisition.
