Flown cable carried to the lunar surface during the Apollo 15 mission, originally from the collection of Commander Dave Scott and used to connect Scott’s space suit to his Primary Life Support System for extravehicular activities. The blue cable measures 17? in length and consists of a set of wires wrapped in cloth and terminating with a robust circular metal connector made by Air-Lock, which is engraved on the top with the part numbers: "Assy. 9046, SN 444." The connector measures 1.5? in diameter and has a functional rotating ring that was used to securely lock the crucial connection in place. In fine condition, with some fraying to cloth cable wrap where it was cut. Accompanied by signed a certificate of authenticity from Scott, which reads: “I hereby certify that. This PLSS Cable…is from my personal collection, and was used by during my EVA’s on the lunar surface to connect my space suit to my Personal Life Support System.” Provenance: Aurora, 2005.
The Primary Life Support System (PLSS) was the backpack-like device which provided oxygen and regulated all necessary functions during extravehicular activity, such as suit pressure, ventilation, and two-way communication. While on the moon, Scott conducted three EVAs for a total time of 18 hours and 35 minutes spent on the lunar surface-an impressive duration made possible by this cable. Scott kept this all-important piece of hardware in his collection for over three decades, as NASA's policy permitted astronauts to keep disposal items from their flights as personal mementos. A truly incredible piece of lunar history.
