Gemini 6A Launch Poster

Gemini 6A was the fifth crewed Earth-orbiting spacecraft of the Gemini series, having been launched after Gemini 7, with the intent of making rendezvous with Gemini 7 in Earth orbit. The astronauts on the 26 hour mission were Walter Schirra and Thomas Stafford. The mission priorities were to demonstrate on-time launch procedures, closed-loop rendezvous capabilities, and stationkeeping techniques with Gemini 7. Other objectives were to evaluate the spacecraft reentry guidance capabilities, and conduct spacecraft systems tests and four experiments. This mission was originally designated Gemini 6 and scheduled for launch on 25 October but was cancelled when the Agena target vehicle failed to go into orbit an hour earlier.
