Rank 92 documents the Infrared Astronomical Satellite (IRAS) — the international JPL, Netherlands, and UK partnership that launched 25 January 1983 on a Delta 3910 and became the first space telescope to map the entire sky in infrared wavelengths (12, 25, 60, and 100 μm). Gerry Neugebauer and Harlan Spitzer championed a 1,083 kg observatory cooled by superfluid helium that catalogued 350,000 infrared sources in just ten months before coolant exhaustion on 21 November 1983. IRAS discovered the debris disk around Vega — proof that other stars host asteroid-belt analogs — and tracked Comet IRAS-Araki-Alcock during an unusually close Earth approach. Wallimilist renders the dewar telescope with solar panels against a stippled infrared nebula field, bold 1983 typography, and dual NASA-JPL footer exactly as the master PNG dictates.
