This dome or hemispherical-shaped helmet was designed to give the wearer a wide range of vision, while maintaining full pressure. The helmet is made of polycarbonate with an anodized aluminum neck ring that fits directly into the neck ring of the suit.
This helmet was constructed in 1964 and was experimental, designed for the series of advanced extra-vehicular suits made for NASA during the 1960s and 1970s.
Transferred from NASA Johnson Space Center in 1977.
