Released on December 10, 2019
Terra, the flagship Earth observing satellite launched December 18, 1999. Having exceeded its expected design life of six years, Terra is an amazing feat of engineering. Terra is the longest continuously operating satellite to capture simultaneous measurements of Earth from five different sensors. Many of the climate data records produced by Terra’s instruments are the longest ever produced by a single satellite mission. Terra’s five sensors ASTER, CERES, MISR, MODIS, and MOPITT record data about land surface, water, atmosphere, snow and ice, and Earth’s energy budget.
