Assembly, Bio-Harness, Aldrin, Apollo 11

This Apollo Bio-Harness was worn by astronaut Edwin "Buzz" Aldrin during his Apollo 11 mission in July 1969.

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 1970.
