By 1963 the one-man space flights of Project Mercury had successfully taken place, and NASA (the National Aeronautics and Space Administration) was ready for a new challenge. That new challenge was to send two men into space at the same time, rather than one, so that it wouldbe possible to conduct a wide variety of new maneuvers and tests. An appropriate name was found for that new project: the new project was called Project Gemini. The name "Gemini" might seem appropriate because it is the name of one of the constellations of stars in the sky, but that is not the real reason for the choice of the name. "Gemini" comes from the Latin word geminus, which means "twin". The constellation Gemini received its name because it consists of two very bright stars with no other bright stars close by, and those stars seem like twins. The NASA project received its name because of the number of men who would be together in the space capsule orbiting the Earth.
