“I tell ya from up here the world is round. It is spectacular. It’s fantastic,” said Gemini XI command pilot Pete Conrad as he and pilot Dick Gordon looked down from their lofty vantage point. Their record-shattering altitude of 850 miles above the Earth was only one highlight of a demanding, three-day mission in September 1966 – 55 years ago.
In mid-1966, Gemini X continued advancing NASA’s capabilities for operating in space with a record-setting, three-day flight. Two astronauts completed rendezvous with two separate targets, retrieved an experiment package from one and set a new altitude record for human flight. All the objectives were designed as stepping stones in preparation for the Apollo Moon landings to follow.
During the summer of 1965, the United States began to pull even in the space race with the Soviet Union. The eight-day Gemini V endurance mission doubled America’s spaceflight record set two months earlier. It also tested technology that would help make longer missions possible in the future.
