At the conclusion of Space Shuttle Mission STS-100, Endeavour landed at Edwards Air Force Base, California, May 1, 2001. There the Orbiter would be readied by technicians at NASA's Dryden Flight Research Center for return to Kennedy Space Center, Florida, atop a 747 carrier aircraft.

The main objective of the STS-100 mission, the sixth International Space Station (ISS) assembly flight, was the delivery and installation of the Canadian-built Space Station Remote Manipulator System (SSRMS), or Canadarm2. In this photograph, astronaut Chris A. Hadfield, mission specialist representing the Canadian Space Agency (CSA), is seen near the Canadarm2, as the new tool for the ISS grasps the space lab pallet.

A convoy of specialized support vehicles follow the Space Shuttle Endeavour as it is towed up a taxiway at NASA's Dryden Flight Research Center on Edwards Air Force Base, California, after landing on May 1, 2001. The two largest vehicles trailing the shuttle provide electrical power and air conditioning to the shuttle's systems during post-flight recovery operations. The Endeavour had just completed mission STS-100, an almost 12-day mission to install the Canadarm 2 robotic arm and deliver some three tons of supplies and experiments to the International Space Station. The landing was the 48th shuttle landing at Edwards since shuttle flights began in 1981. After post-flight processing, the Endeavour was mounted atop one of NASA's modified Boeing 747 shuttle carrier aircraft and ferried back to the Kennedy Space Center in Florida on May 8, 2001.
