Project Gemini

Bridge to the Moon. Gemini came right after Project Mercury and before Apollo, giving NASA a chance to figure out how to dock spacecraft together, walk in space, and stay in orbit for days at a time, all skills needed for the Moon landing.

Two astronauts together. Unlike Mercury missions with just one astronaut, each Gemini spacecraft carried two crew members, which let them practice teamwork and complex maneuvers in orbit.

Practice in low orbit. All ten Gemini missions flew in low Earth orbit, relatively close to our planet, which was the perfect place to test everything before going to the Moon.

Short window of time. Project Gemini launched and completed all its missions in just one year, between 1965 and 1966, with 16 different astronauts flying during that busy stretch.

Real-world space skills. Astronauts learned to dock with other spacecraft, conduct spacewalks outside their ship, and maneuver in space, discoveries that would be essential for the Apollo program's success.
