Space Shuttle Endeavour has been given a piggyback on a Boeing 747 to the Edwards Air Force Base in California before being moved to a museum.
The 747 carrying the newly retired spaceship touched down safely at Edwards, located in the Mojave Desert north of Los Angeles.
Endeavour is scheduled to take off again for its final ferry flight to Los Angeles International Airport on Friday, marking the final airborne journey of the entire space shuttle fleet.
It was added to the shuttle fleet after Challenger was destroyed by an accidental explosion that killed seven astronauts in 1986. Endeavour has flown 25 missions in space and logged nearly 123 million miles in flight during 4,671 orbits.
The 75-ton spacecraft will then undergo preparations to be moved 12 miles through the city's streets from the airport to its permanent home at the California Science Center in downtown Los Angeles, where the shuttle will be put on public display.
