On Aug. 29, 1965, two NASA astronauts returned from their record-breaking Gemini 5 mission.
Astronauts Gordon Cooper and Pete Conrad spent eight days in Earth orbit, and for the first time, the United States set a world record for the duration of a crewed spaceflight.
The Gemini 5 mission launched on Aug. 21, 1965 atop a Titan II rocket from what was then the Cape Canaveral Air Force Station (now the Cape Canaveral Space Force Station) in Florida. While in orbit, the astronauts were supposed to test rendezvous capabilities and maneuvers using a pod that deployed from their spacecraft. But due to an electrical problem, they had to cancel those plans along with several science experiments.
