This helmet was used by astronaut Scott Carpenter during training sessions prior to the Gemini missions of the 1960s.
The helmet had a double lens shield (visors) for visual, thermal, and micrometeorite protection. These two over-visors were constructed of Lexan and provided micrometeoroid and thermal protection for the faceplate and the astronaut.
The helmet was constructed of fiberglass and epoxy resin and was molded to fit directly into the neck bearing disconnect. A Plexiglas visor, capable of being raised for access, was attached with pivots, and when lowered into pressure sealing position, it locked in place with a latch. Communication devices with suede-covered ear pads were incorporated into the helmet.
Transferred to NASM in 1973.
