Neil Armstrong's Lunar Module descent monitoring chart used during training for the Apollo 11 mission, comprised of seven 8.5 x 10.5 chronopaque photographic lunar map panels taped end-to-end, measuring an overall 8.5 x 73.5 when unfolded. The back of the first sheet is marked: "Descent Monitoring Chart, SEB32100025-006, 16 July, Site 2, Training Copy, Updated 26 June." The legend on the map's third plate reads: "Edition 1, LM Descent Monitoring Chart - Sheet 2, 16 July 1969 Launch Date - Landing Site No. 2." The chart shows landmarks of the moon's surface witnessed around the time of the LM Eagle's Power Descent Initiation (PDI): the first two panels map the surface from fifteen minutes before PDI to two minutes before PDI. The five other plates trace the LM's expected path over the lunar surface from four minutes before PDI to five minutes after, with the moment of PDI denoted at the center. On these five plates, the planned LM descent path is printed as the solid white center line, and expected viewing limits from the LM's windows are demarcated by dashed white lines. The craters Maskelyne, Maskelyne B, and Maskelyne G are seen on the last plate. The actual Apollo 11 landing site is located about 210 kilometers to the west-southwest of the crater Maskelyne. In fine condition. Accompanied by two letters of provenance from The Armstrong Family Collection, signed by Armstrong's sons, Rick and Mark, both encapsulated by CAG. Provenance: Heritage Auctions, The Armstrong Family Collection III, July 2019. A remarkable piece from the collection of Neil Armstrong, used in training to help familiarize him with the landmarks he would see en route to the lunar surface to become mankind's first moonwalker.
