This pressure helmet was worn by astronaut Alan Shepard, Commander of the Apollo 14 mission launched on January 31, 1971.

The Apollo pressure helmet was a transparent bubble designed to attach to the spacesuit neck ring. It was constructed of a polycarbonate shell with a red anodized aluminum neck ring, a feed port, a vent pad and duct assembly attached to the rear and a valsalva device attached to the inner ring.

There were two configurations used on Apollo suits which were not interchangable, the earlier configuration was anodized blue, with the later configuration being anodized red.

NASA transferred the pressure bubble to the National Air and Space Museum in 1972.
