First episode of a series devoted to the Gemini program. It introduces the program and its objectives and reviews its crewed missions one by one, from Gemini 3 to Gemini 12.

Gemini was NASA's second crewed program. It ran from 1961 to 1966 as a bridge between Mercury and Apollo. Its name, Latin for "twins," refers to its two-astronaut crews. It had four objectives: mastering extravehicular activity, demonstrating long-duration flights, testing orbital rendezvous and docking, and studying reentry. The program comprised 12 missions, 10 of them crewed.

Gemini 3, launched on March 23, 1965 with Gus Grissom and John Young, was the first crewed mission and carried out orbital changes. On board, Young smuggled a corned beef sandwich against regulations. On Gemini 4, in June 1965, Edward White performed the first American spacewalk, lasting about 23 minutes. The first spacewalk of all had been Alexei Leonov's, on Voskhod 2, on March 18, 1965. Gemini 5, with Gordon Cooper and Charles Conrad, set a new duration record of 8 days, 22 hours and 55 minutes. In December 1965, Gemini 6A and Gemini 7 achieved the first rendezvous between crewed spacecraft; Gemini 7, with Frank Borman and Jim Lovell, lasted 14 days. Gemini 8, with Neil Armstrong and David Scott, achieved the first docking, but an attitude-control malfunction forced an early splashdown. Gemini 12, with Jim Lovell and Buzz Aldrin, closed out the program in November 1966 with a spacewalk lasting almost five hours.
