SPACE SUIT SCHEMATIC CARRIED ON APOLLO 13.
Flown Extravehicular Mobility Unit Detailed Schematic, 2 EMU, a drawing from the Apollo 13 LM Systems Data Book. NASA/MSC, April 1969. Single folded sheet, 10½ x 36 inches, with an "EMU" tab.

This schematic is the one single flown sheet from Apollo 13 that contains precise engineering information on the crew's space suits. An enlarged outline of the suit is shown with all subsystems that supply the power and life support functions. Labeled drawings include the helmet latching device, communications headset, ventilation diverter and pressure relief valves, oxygen and cooling water connectors, pressure gauges, clip restraints, and the biomedical injection patch. Also shown are schematics of the Oxygen Purge System (OPS), extensive details of current flows for the astronaut biomed system, and components of the main oxygen and liquid cooling systems. Additionally, there is a full face drawing of an Omega Speedmaster wrist watch and relative suit placement.
The oxygen and cooling was provided to the Apollo space suit by Command or Lunar Module onboard systems if needed while worn inside these vehicles or with the Portable Life Support System (PLSS a.k.a. "backpack") while out of the lunar surface.
INSCRIBED with a humorous comment and SIGNED: "Flown to the moon on Apollo 13 – A schematic of the simple Space Suit (EMU)! Fred Haise, Apollo 13 LMP," and further SIGNED and INSCRIBED, "James Lovell, Apollo 13 CDR."
