Collection Item Summary:

This helmet was worn by astronaut James McDivitt as Commander of the Gemini 4 mission in June 1965, which was the first manned Gemini mission in which a US astronaut "walked in space."

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 from NASA in 1967.
