Project Gemini
Bridging the Gap to the Moon
Program Overview
Project Gemini was NASA's second human spaceflight program, conducting ten crewed flights in 1965 and 1966. Gemini's objective was to develop the space travel techniques necessary for Apollo's lunar landing missions. Gemini astronauts perfected orbital maneuvers, rendezvous and docking of two spacecraft, extravehicular activity (EVA) or spacewalks, and proved that pilots could endure weightlessness for up to two weeks. It was during Gemini that NASA achieved parity and eventual superiority in the Space Race, training a critical cohort of astronauts who would command Apollo.
