    Transmitted Duke's vital signs to Mission Control throughout the mission.

    Apollo 16 Lunar Module Flown and Surface-Used A7L Bio-Harness with Complete Kennedy Space Center Documentation. A Beta cloth-covered electrical bio harness, 8" x 10.5" overall, that connected the sensors on Charles Duke's chest to the main communications harness of his spacesuit. Printed on the harness are the words, "Harness Assy, Bio, S/N A7L 101054-04" which is crossed out with a red line and "A7LB 109043 01" stamped next to it, "Cicoil Corp 770A100-4", "S/N 117", and "Mfg date 468". The harness has three small metal female plugs (red, yellow, and blue) that connected with the body sensors and a rectangular metal female plug that connected to the communications harness. This system transmitted Duke's primary medical data back to Mission Control during the entire flight, including Duke's three lunar EVAs which totaled more than twenty hours. The documentation is the complete NASA Acceptance Data Package from ILC Industries for this particular Bio Harness. This 50+ page document traces every aspect of its manufacture, testing and flight history; it specifies in several places that this harness was selected for and flown on Apollo 16. Also, a John F. Kennedy Space Center, Astronaut Suiting Operations report for Apollo 16, page 2-12.3 shows under the section "Space Suit Equipment": Stowage list Item No. 0216, Bioinstrumentation Harness A7LB-109043-01 *A7L 101054-04 [prior number], S/N 117 was for the LMP, Charles Duke. Copies of stowage list pages also included. An interesting piece of equipment that spent twenty hours on the lunar surface. Very fine condition. From the Steven R. Belasco Collection of Space Memorabilia.
