Overview of the Earth Observing One (EO-1) Mission

As reported at the IGARSS-2001 Symposium, the first 120 days of the EO-1 mission, constituting the Accelerated Mission, far exceeded the goal of acquiring sufficient data to insure meeting minimal EO-1 validation requirements. The strategy of using Southern Hemisphere test sites during the Northern Hemisphere winter solstice left EO-1 with data for a variety of ecosystems under varying conditions. These data, collected primarily in Argentina and Australia, have been extensively analyzed by the EO-1 Science Validation Team (SVT). Additionally, during the remainder of the first year of operation, EO-1 accumulated a rich legacy of data for a global variety of ecosystems under varying conditions to complete the Base Mission. The SVT will continue to analyze these data through September of 2002. EO-1 data became public in December of 2001 at the onset of the EO-1 Extended Mission. This Extended Mission opened opportunities for the public to commission EO-1 data collects. Data from both the Base Mission and Extended Mission are publically available from the EROS Data Center. Results of both phases of the EO-1 Base Mission as well as early findings from the Extended Mission are summarized.
