EXPOSED TO THE LUNAR ENVIRONMENT FOR MORE THAN 18 HOURS AND DEEP SPACE ENVIRONMENT DURING MANKIND'S FIRST DEEP-SPACE EVA PERFORMED BY AL WORDEN.
The OPS supplies the EMU with oxygen purge flow and pressure control for certain failure modes of the PLSS or PGA during EVA.
In the event of a PLSS failure, the OPS flow is regulated to 3.7 +/- 0.3 psid for 30 minutes to provide breathing oxygen to the crewman, to prevent excessive carbon dioxide buildup, and to provide limited cooling.
In the lunar EVA configuration, the OPS is mounted on top of the PLSS. During contingency EV transfer from the lunar module, however, the OPS is attached by straps to the lower front torso of the PGA.
Originally from the collection of Apollo 15 commander Dave Scott - own a piece of history :
Worn on the lunar surface by Scott as part of his PLSS and carried on the first lunar rover for a total of more than 18 hours then used again by Alfred Worden during his first deep-space EVA!
The beta cloth fragment comes from the beta cloth protection of the OPS and is encased in a high end custom-made acrylic.
Moondust :
Aside from having a strong certification the existence of lunar dust in the beta cloth is one of the best proofs that the artifact actually went to the moon. We have closely examined the beta cloth and found evidence of lunar dust throughout the entire beta cloth segment. Individual fragments contain traces/grains which can be seen through a 60x(or more) microscope with a good eye although density is not comparable with our Apollo 16 netting presentations!
Your presentation package includes :
Acrylic containing surface and rover used beta cloth artifact
Certificate of authenticity
Background documentation
Made out of the most advanced acrylic available on the market today - Plexid 55 - these are ultraclear with no discoloration over time. Unlike other privately made acrylics or lucites these are real blocks, not cheaply glued or screwed together. Each block is about 5''x3''x1'' in size - perfect for any office table or even flat down in a cabinet.
Only 50 such acrylics were made.
Disclaimer: Although the original piece comes from the collection of Apollo 15 mission commander David Scott, Mr. Scott is not involved in this edition nor does endorse it.
