1970s Pioneer — 2 museum-grade prints that set the mood. Pioneer 11 was the first human-made object to fly past Saturn, arriving 1 September 1979 after using Jupiter's gravity to reshape its solar-system trajectory. The mission discovered Saturn's F ring and provided the first close measurements of the planet's magnetosphere and ring structure. Viking 2 touched down at Utopia Planitia on 3 September 1976 — the second successful Mars soft landing after its twin at Chryse Planitia. The mission's biology experiments returned inconclusive but chemically reactive results that shaped decades of Mars life-detection strategy.
