Rank 85 documents the Fermi Gamma-ray Space Telescope — the 4,303 kg Goddard observatory that opened all-sky gamma-ray astronomy from 20 MeV to 300 GeV when Delta II 7920H lifted it on 11 June 2008. The Large Area Telescope (LAT) and Gamma-ray Burst Monitor (GBM) pair scan the cosmos daily, cataloguing more than 300 gamma-ray pulsars, tracking blazars and active galactic nuclei, and mapping the mysterious Fermi bubbles — twin lobes of high-energy emission extending 25,000 light-years above and below the Milky Way's center. Neil Gehrels and Julie McEnery led the mission that named itself after the physicist who first achieved controlled nuclear reaction; extended operations continue into the 2020s with no end date. Wallimilist renders the LAT tracker hero, vertical FERMI GAMMA-RAY spine, stippled burst rays, and Explorer footer exactly as the master PNG dictates — 2008 launch kicker, all-sky mission palette, and curator copy on high-energy sky mapping.
