Rank 102 documents Terra — the flagship Earth Observing System spacecraft that has monitored our planet's climate indicators daily since 1999. Launched 18 December 1999 aboard Atlas IIAS from Vandenberg, the 4,864 kg Goddard spacecraft carries MODIS, ASTER, CERES, MISR, and MOPITT — five instruments that together track land cover, ocean colour, atmospheric aerosols, cloud properties, and carbon monoxide across 36 MODIS spectral channels. Operating in a 705 km, 10:30 sun-synchronous morning orbit as anchor of the EOS morning constellation, Terra delivers daily global coverage used by more than ten thousand research teams. MODIS fire detection, vegetation indices, and aerosol optical depth became operational products for disaster response and climate monitoring worldwide. Still operating after twenty-five years, Terra proved that long-lived Earth observatories could anchor interagency climate science. Wallimilist renders the gold-silver bus with MODIS barrel, MISR cluster, blue solar array, hurricane swirl on Earth below, vertical TERRA title, and EOS flagship kicker exactly as the master PNG dictates — morning constellation kicker, 1999 Earth palette, and curator copy on climate observatory heritage.
