Which mission number concluded the Space Shuttle Program with the Orbiter Atlantis?
Answer
STS-135
The mission that served as the closing chapter of the three-decade-long era of human spaceflight utilizing the Space Shuttle fleet was officially designated as STS-135. This mission was significant because it was an encore flight, meaning it was added to the schedule late in the program's life specifically to maximize the cargo payload delivered to the International Space Station (ISS) before the fleet was permanently grounded. Although STS-135 was the final flight, the Space Shuttle Program had officially begun with STS-1, highlighting the extensive timeline covered by the program starting in 1981.
