Lot 5039: Extremely detailed suit and cabin pressurization schematic for the Apollo 9 Command Service Module, one page, 36.25 x 10.5, copiously annotated by NASA Flight Director Gene Kranz. The schematic depicts the inner workings of the pressurization systems critical to survival in the spacecraft, with many areas color-coded in green, red, purple, and yellow. Kranz heavily annotated the entire schematic in red ballpoint, including longer notes in the left margin concerning "Glycol Inlet," "Cabin Pressures," "Water—Waste…Potable," "Suit Choked Flow," and "O2 Flow—Normal Metabolic." The numerous notes throughout the diagram generally give specific measurements, such as: "Raises suit to cabin + 4 psi in ~75 sec," "Bypass valve opens at ?P=.5? H2O in case of debris trap clog," "CO2>7.6," and "H2O/Gly Res, 20±2 psi." In fine condition. Accompanied by a signed letter of authenticity from Kranz, in part: "The Apollo Suit & Cabin Pressurization schematic for the Apollo 9 Command Module Gumdrop that accompanied this letter comes from my personal mission files." In addition to these systems inside the CSM Gumdrop—so named because of its shape—the Apollo 9 spacesuit was the first to have its own life support system rather than being dependent on an umbilical connection to the spacecraft. An incredibly detailed schematic rife with important notes and annotations.
