An Apollo 15 PLSS Beta cloth label headed "Water Reservoir Recharge," 9.5 x 10.5, representing the procedure used to recharge the PLSS with water after each lunar EVA when the astronauts returned to the LM. The water was used to cool the crewmen (CDR and LMP) by circulating the water through the astronauts Liquid Cooling Garment (LCG) using the PLSS water pump and cooling the water by the process of sublimation (liquid water to solid ice). This example of the recharge label shows attempts to change the numbers as a result of tests conducted at KSC after the labels had been printed at MSC; the unsuccessful attempts to modify the numbers resulted in this unusable label. In fine condition. 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.
