Rank 66 documents Apollo 16 — the only Apollo mission to land in the lunar highlands and the penultimate crewed lunar landing. Launched 16 April 1972 aboard Saturn V SA-511, John Young, Charles Duke, and Thomas Mattingly targeted Descartes — a region scientists initially believed was volcanic until Apollo 16 samples proved it was impact breccia from ancient basin-forming events. Orion LM landed 21 April; Young and Duke conducted three EVAs totalling 20 h 14 m, driving the LRV 27 km across bright ray ejecta and sampling House Rock and other massive boulders. Young's jump salute photograph became an iconic image of lunar exuberance. Mattingly, after an SPS issue delayed circularization, performed extensive solo CSM science in Caspar including subsatellite operations. Splashdown 27 April. Wallimilist renders the LRV crossing Descartes bright rays, Orion LM on slope, Stone Mountain massif, and foil APOLLO 16 title exactly as the master PNG dictates — highlands geology kicker, 1972 lunar palette, and curator copy on breccia sampling and Young's jump.
