NASA's final Space Shuttle mission was STS-135, which was conducted by the Space Shuttle Atlantis. The mission was launched on July 8, 2011, and landed on July 21, 2011. STS-135 was the 33rd and final flight of the Space Shuttle program. It delivered supplies to the International Space Station (ISS) and marked the end of the Space Shuttle era, concluding a program that had been in operation for over 30 years. The Space Shuttle Atlantis, along with the other orbiters in the fleet, was retired after this mission, and NASA shifted its focus to future deep space exploration missions, such as the Space Launch System (SLS) and the Orion spacecraft.
