Seven granules of activated charcoal from the same batch used in the PLSS oxygen filtration cartridges flown on Apollo 11, contained within a Millipore Filter Corporation plastic petri dish. In fine condition. Accompanied by a detailed letter of provenance from Dan Schaiewitz, describing the use of the filtration cartridges in the PLSS and the history of these specific granules. In part: "One week before Apollo 11 launch we noticed that one of the six LIOH cartridges assigned to the Apollo 11 PLSSs had been exposed to an out of spec high temperature. I hand carried the cartridge from KSC to Hamilton Standard headquarters in Windsor Locks Conn. allowing engineers to inspect and test the cartridge to determine if this was an isolated case. I was in the laboratory and witnessed the inspection and testing of the cartridge in question. After the cartridge was disassembled and tested, I asked if I could have a few of the activated charcoal granules and was given the samples in my collection…The significance of the samples is that they were from the same batch flown in the cartridges used in the Apollo 11 PLSSs." From the collection of Dan Schaiewitz, who worked as Extravehicular Crew Training Engineer at KSC. View Dan's many Collect Space posts here. Engineer Dan Schaiewitz gives us a fascinating firsthand glimpse into his experiences on the cutting edge of space exploration during the Apollo missions, in this podcast.
