NASA’s Discovery space shuttle will make its final lift-off on Saturday, but there will be no launching involved. The retired space shuttle will be placed atop a giant Boeing 747 jet during its ride from the Kennedy Space Center in Florida to its final home at the Smithsonian Air and Space Museum outside Washington, D.C. Weather permitting, the Discovery is set to take off at dawn, with crowds expected to gather in D.C. to watch its landing. NASA flew its last shuttle flight in July and has since been prepping the spaceships to be displayed in museums.
