Satellite family: EOS (Earth Observing System)

The Earth Observing System (EOS) is a major component of NASA's Earth-Sun System Missions. The mission includes a series of satellites, a science component, and a data system supporting a coordinated series of polar-orbiting and low inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans. EOS is enabling an improved understanding of the Earth as an integrated system.
