Assembly, Bioinstrumentation, Apollo 8


Display Status:

This object is not on display at the National Air and Space Museum. It is either on loan or in storage.

Collection Item Summary:

This Apollo bio-harness was worn by an astronaut aboard the Apollo 8 mission in December 1968. The manufacturing date indicates that the biobelt pouch is from a later Apollo mission and was probably combined with the Apollo 8 hardware at some point during the Museum's artifact acquisition.

The Apollo Bio-Harness Assembly was worn under either the intra-vehicular (IV) or extra-vehicular (EV) pressure suit. It consisted of a cotton duck belt with teflon-coated beta cloth pockets into which the electrocardiograph signal conditioner, the impedance pneumograph signal conditioner, and a DC-DC converter were inserted. These instruments monitored the physiological functions of the astronaut. The belt was fitted with snap fastners which attached the assembly to either the constant wear garment or the liquid cooling garment.

NASA transferred this object to the Museum in 1977.
