Earth Observing-1 (EO-1)

NASA's Earth Observing-1 (EO-1) satellite, launched in 2000, was a one-year technology demonstration mission to validate the Landsat Data Continuity Mission. As the end of the mission approached, the remote sensing research and scientific communities expressed high interest in continued acquisition of image data from EO-1.

Recognizing the remarkable performance of the satellite's instruments and the exceptional value of the data, the USGS and NASA agreed to continue the EO-1 Program as an Extended Mission. Image data acquired by EO-1 are archived and distributed by EROS and in the public domain.

The Earth Observing System (EOS) is the centerpiece of NASA's Earth Science Enterprise Program. EOS is 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.

The USGS participates in NASA's Earth Science Enterprise Program through its involvement in the development and operation of the EOS Data and Information System (EOSDIS). EOSDIS manages data from past and current NASA Earth science research satellites and field measurement programs, and provides data archiving, distribution, and information management services. The EOSDIS Distributed Active Archive Centers (DAACs) were established to provide expertise in one or more of the disciplines that collectively constitute global change science. EROS serves as the DAAC responsible for processing, archiving, and distributing EOS land science data and products. Learn more about EOS:
