Status: Current, Extended Mission
Mission Category: Other
Launch Date: November 21, 2000
Launch Location: Vandenberg Air Force Base, CA

The Earth Observing (EO-1) satellite was a one-year technology validation/demonstration mission designed to demonstrate new technologies and strategies for improved Earth observations; however, it has been extended beyond one year and still collects data. The satellite contains three observing instruments supported by a variety of newly developed space technologies.
