APOLLO 12 EKG READING DURING MOONWALK
SIGNED BY ALAN BEAN.
Electrocardiogram strip from NASA Mission Control during first Lunar EVA, November 19, 1969, Provenance: Dr. Lawrence Kuznetz, member of the Apollo 12 Metabolic Assessment Team.
SIGNED & INSCRIBED: "Alan Bean / Apollo 12 LMP"
A unique item from the second manned Lunar landing showing the EKGs and respiration rates of all three members of the crew: Command Module Pilot Richard Gordon Jr.; Commander Charles "Pete" Conrad Jr.; and Lunar Module Pilot Alan Bean. Each set of readings is labeled with the corresponding astronaut's title. A document from Dr. Kuznetz describes the piece and its importance to the mission. In part: "This EKG was used by the Flight Surgeon in Mission Control to assess the astronaut's physiological condition while walking on the lunar surface, while the pulse rates derived from the EKG, together with data from the Liquid Cooled Garment (LCG) and the spacesuit Portable Life Support System Oxygen tank (PLSS 02) were used by the Metabolic Assessment Team (MAT) and the EVA flight controller to determine the LMP's work task (metabolic) rate for various lunar surface activities; spacesuit consumable usage rate; remaining allowable time on the surface; bingo safety limit time left and other parameters.
Together with similar data from Apollo 11, this represents the first time such information was ever recorded for humans on the surfaces of another planetary body. As such, in is considered to be historic information. The EKG signals for this chart were created in real time by 3-lead EKG transducers and pressure transducers (for respiration) worn on the skin of the astronaut and connected to his Bio-harness. The Bio-harness transmitted the data via the spacesuit PLSS communication system to the Lunar Module, which in turn sent it via the Deep Space Network to NASA's Mission Control in Houston, where it generated this strip in real time. During the two Apollo 12 EVAs, this data was crucial for determining the health of astronauts, the performance of their spacesuits, the energy cost of working on the lunar surface, the allowable time remaining for the EVA and other critical information."
