Project Gemini Missions

The Gemini/Titan-II launch vehicle #1 lifts off at Cape Kennedy, Florida.

Gemini I

Gemini 1 was an uncrewed orbital test of the Titan 2 launch vehicle, the Gemini spacecraft structural integrity, and the launch vehicle-spacecraft compatibility.

The Gemini Titan II Launch Vehicle lifts off

Gemini II

This was the second uncrewed Gemini test mission, consisting of a sub-orbital ballistic flight and reentry with the primary objectives being to demonstrate the adequacy of the spacecraft reentry module's heat protection during a maximum heating rate return, the structural integrity of the spacecraft, and the performance of spacecraft systems.
