Objectives and Applications
|
6-year nominal mission life, currently in extended operations. In late 2020, Terra began to drift in its orbit when the mission stopped performing inclination adjust maneuvers. Atmospheric dynamics/water and energy cycles, atmospheric chemistry, physical and radiative properties of clouds, air-land exchanges of energy, carbon and water, vertical profiles of CO and methane vulcanology.
