BOSTON, MASS.- The backpack strap used by Moonwalker Edgar Mitchell during the Apollo 14 Mission will be auctioned by Boston, MA based RR Auction.

The Primary Life Support System (PLSS) backpack strap measures 19″ long and approximately 3″ wide, signed and is flight-certified.

Apollo 14 was the first lunar landing devoted primarily to scientific exploration, and completed two periods of surface exploration, each exceeding four and one-half hours. The first was devoted to setting up and activating a telemetry station. The second period of extra-vehicular activity (EVA) was devoted to collecting documented soil and rock samples from nearby Cone Crater. The PLSS was the backpack-style life support system that enabled astronauts to conduct extra-vehicular activities without being tethered to the life support systems of the spacecraft, allowing for complete freedom of movement.

During the mission, Mitchell would spend a cumulative time of 9 hours and 23 minutes on the lunar surface.

“Considering Edgar Mitchell would have worn this strap during the entire time on the surface of the moon—makes it an absolutely amazing and historically important piece,” said Bobby Livingston, Executive VP at RR Auction.

Additional items include:

Flown scissors carried aboard the Apollo 15 mission and used on the lunar surface by Commander David Scott. Accompanied by a signed letter of provenance from Scott that states that they were used during launch, mission operations, and on the surface of the Moon.

Edgar Mitchell’s Apollo 14 flown Heel Restraints that were flown into lunar orbit aboard Kittyhawk on the Apollo 14 mission, which launched from Cape Kennedy on January 31, 1971. These heel restraints locked the astronauts' feet in place for safety during liftoff of the Saturn V rocket from Earth.

Gene Cernan’s Apollo 17 Flown EVA/EXP Checklist. The checklist consists of 166 pages (83 individual sheets), including 27 pages filled out with in-flight writing, much of which remains scientifically relevant today. The highlight of this checklist is undoubtedly the presence of three pages of solar corona observation sketches: one features a large sketch with notations.

Jim McDivitt’s Apollo 9 Flown Electrical Biomedical Harness that would have been worn under the underneath Constant Wear Garment when in the spacecraft or under the Liquid Cooling Garment during EVA to provide crew biotelemetry monitoring of vital signs such as pulse and respiration.

Dave Scott’s Lunar Surface-used Lunar Rover Map. The map was mounted on the Rover throughout the three days of surface excursions to be readily available. The Map contains traces of lunar dust surface and was exposed to the temperature extremes, radiation, and Solar Wind on the surface of the Moon.

Online bidding for the Space Exploration Auction from RR Auction is scheduled to take place April 16 to April 23.
