Early handwritten notes in pencil by Deke Slayton from the late 1950s, early 1960s, with content relating to the testing of rockets from the Redstone family, unsigned, five total pages 8 x 10.5, which begins with a page headed “Control & Guidance – Redstone,” which reads below, in part: “53 Redstones fired, 11 failures / 2 due to errors in adjusting control system / 1 due to rough combustion (Blew 10 sec. Off pad) / 2 fire in aft section causing loss of control / 1 nose cone failed to separate… / 1 yaw axis control inoperative - drifted out of control.” The remaining pages feature Slayton’s handwritten on work conducted by noted German engineers and rocket scientists Wernher von Braun, Joachim Kuettner, and Heinz-Hermann Koelle.
Examples include: “Von Braun / Juno-2, NASA satellite probes of approx. 100 payload mod. Jupiter booster using Explorer 2nd stage / Redstone-Mercury booster - Mod w/ more fuel, alcohol & O2 fueled”; “Dr. Kuettner / Redstone profile / 5.5 G, Mach 5.9, 203,000 at cut off / Alt. 667,000´, Mach 7.75, 5.5 min weightless”; “Mr. Koelle / Future Projects / Saturn I - 8 Jupiter 1st stage, Titan 2nd stage, 1,500,000 / Saturn II - 2,000,-000 / Nova - 6,000,000.” The last two pages feature Slayton’s notes from a “Lt. Hornsby” on Redstone and Jupiter tests. In very good condition, with creasing and staining, not affecting readability.
