Mercury-Atlas 9 was the final crewed space mission of the U.S. Mercury program, launched on May 15, 1963, from Launch Complex 14 at Cape Canaveral, Florida. The spacecraft, named Faith 7, completed 22 Earth orbits before splashing down in the Pacific Ocean, piloted by astronaut Gordon Cooper, then a United States Air Force major. The Atlas rocket was No. 130-D, and the Mercury spacecraft was No. 20. As of January 2024, this mission marks the last time an American was launched alone to conduct an entirely solo orbital mission.

Launch Complex 14 (LC-14) is a launch site at Cape Canaveral Space Force Station in Florida. LC-14 was used for various crewed and uncrewed Atlas launches, including the Friendship 7 flight aboard which John Glenn became the first American to orbit the Earth in February 1962.
