Rank 103 documents Aqua — the Earth Observing System afternoon anchor that revolutionized water cycle and weather forecasting from orbit. Launched 4 May 2002 aboard Delta II 7920 from Vandenberg, the 2,934 kg Goddard spacecraft carries AIRS, AMSU, CERES, MODIS, and AMSR-E — instruments that track precipitation, ice, water vapor, clouds, and ocean properties across the planet. Operating in a 705 km, 1:30 sun-synchronous afternoon orbit complementary to Terra's morning pass, Aqua's Atmospheric Infrared Sounder delivers 2,378 infrared channels that improved weather forecast accuracy by more than twenty-four hours — a operational breakthrough for NOAA and international meteorological agencies. Named for water — aqua in Latin — the mission became critical for drought monitoring, flood prediction, and ice cap tracking. AMSR-E ceased in 2011; other instruments continue operating. Wallimilist renders the bus with prominent AIRS cooler, MODIS aperture, water vapour swirls on Earth, AQUA title, and water cycle kicker exactly as the master PNG dictates — afternoon constellation kicker, 2002 Earth palette, and curator copy on humidity science heritage.
