Rank 47 in NASA Heritage Collector documents Galileo as the first dedicated Jupiter orbiter — launched from Atlantis on STS-34 in October 1989, cruising six years before December 1995 probe entry and orbital science that transformed the Jovian system. The 339 kg atmospheric probe survived a 230 km/s entry to sample ammonia clouds while the 2,223 kg orbiter executed thirty-five Jupiter orbits, imaged Io's active Prometheus plume, and assembled evidence for a subsurface ocean beneath Europa's fractured ice shell. Galileo also observed Comet Shoemaker-Levy 9's impacts in 1994 — the first direct watch of cosmic collision geology. Wallimilist renders banded Jupiter, probe entry flare, Io volcanism, and Europa ice fractures exactly as the master PNG dictates — stacked GALILEO title, 1995 marker, and curator copy on outer-planets reconnaissance.
