Pressure Suit Cover-layer, Gemini, Cernan

This cover-layer was worn during training by astronaut Eugene "Gene" Cernan, Pilot of the Gemini IX-A mission that occurred in June 1966.

The G-4-C spacesuit's cover-layer featured a slipover jacket to minimize bulk during launch, entry, and closed hatch orbital operations. The cover-layer is made of high-temperature nylon, later called Nomex, and was designed to provide thermal protection for the astronaut during the mission. Except for common thermal cover garments for Gemini V and VI-A, all other G-4-C cover garments were mission specific. At least forty-two G-4-C suits were made, of which sixteen saw flight.

Following the Gemini IX-A mission, Cernan's cover-layer was removed by NASA for testing, and only the pressure garment was transferred to the Air and Space Museum. This cover-layer, used during training, was transferred at a later date.

NASA transferred this cover-layer to the museum after the Gemini program.
