Rank 74 documents Pioneer 11 — the 259 kg Ames Research Center bus that became the first spacecraft to reach Saturn after a December 1974 Jupiter flyby at 43,000 km bent its trajectory outward. Launched 6 April 1973 on Atlas-Centaur, Pioneer 11 crossed the asteroid belt, measured Jupiter's magnetosphere, and on 1 September 1979 passed Saturn at 21,000 km — discovering the F ring and confirming that Titan's atmosphere would block a Cassini-style descent decades early. James Van Allen and John Simpson's instrument heritage rode on RTG power that faded until the last signal in September 1995. Wallimilist renders the 2.74 m dish probe LARGE inside a navy arched frame with Jupiter and Saturn co-present exactly as the master PNG dictates — JUPITER FLYBY → FIRST SATURN FLYBY kicker, 1973 mission line, and LAUNCH 6 APR 1973 footer.
