Which Orbiter performed the final Space Shuttle Program flight?
Answer
Atlantis
The Orbiter selected to fly the closing mission of the Space Shuttle Program, STS-135, was Atlantis. This vehicle was crucial for delivering the final substantial inventory of supplies to the International Space Station before the fleet was decommissioned. Atlantis joined Discovery and Endeavour as active orbiters toward the end of the program, while Challenger and Columbia were tragically lost in prior accidents. Following its return, Atlantis transitioned into a permanent static display at the Kennedy Space Center Visitor Complex.
