Gemini development glove, 1965-1966.
© Science Museum / Science & Society Picture Library
An experimental glove which was made during development work for the first American Extravehicular Activity (EVA) spacesuits, used on NASA's Gemini misions of 1965 and 1966. Since human beings can breathe oxygen at a presure of about 0.3 atmospheres spacesuits are presurised with oxygen, as the lower presure simplifies construction. They must have special joints to allow movement, otherwise they would become rigid. A locking ring at the wrist secures the glove to the spacesuit.
