A very desirable selection of NASA headgear from the Smithsonian National Air and Space Museum collection. From left to right:
– Universal Hamilton Standard A-4H of 1964 used in a lot of suits made for tests, system evaluation and training.
– ILC Industries SPD-143-1a helmet employed in the AX1L Pre-Apollo competition spacesuit prototype, 1963: it was latter recycled to be used with other suits for training, tests, etc.
– Gemini Protective “bone dome” of the David Clark G5C suit envolved in the Gemini VII, 1965.
– B.F. Goodrich Mercury Helmet,i n this case it’s a training example employed by Wally Schirra, 1960.
Pick your favorite. I got mine.
