Flown single-sided command module cue card from the Apollo 17 mission, 5.75 x 4.5, stamped on the reverse with flight certification, “Flown to lunar orbit aboard the Apollo 17 CM ‘America,’” and signed in blue ink, “Gene Cernan.” The cue card, dated November 2, 1972, is headed “DOI 1 Limits” and lists starting steps for orbit insertion as well as a list of reasons for possible system failure, including: “ECS: Cabin, Fire or Smoke, 02 Manf (Leak), (2) Main Reg, Prim Rad, Glycol (leak), Humidity High, (2) Suit Comp & Vac Clnr, Suit Cir, (3) OB Dumps, CRY: 02 or H2 Tank, EPS: (2) Fuel Cell, Entry Bat, Main Bus, Bat Bus, AC Bus, Bat Relay Bus, (2) Inv, A AC1 or 2.” In fine condition. One of two ways to approach the moon—the other being a direct lunar descent—a descent orbit insertion is attempted after executing a retrograde lunar orbit insertion (LOI) maneuver at or near periselene. After orbiting in the capture orbit for one or more orbits, the DOI is performed to lower periselene and start the descent to the lunar surface. An exceptional astronaut-certified piece from this historic final Apollo mission. Pre-certified Zarelli Space Authentication.
