Extended Mission Pages

This section of the website describes the very important post-baseline Extended Mission phase. It documents expanded public access to EO-1 image data and the transformation of the mission into an advanced development sensor web and testbed activity. Use the links to the left to navigate through the Extended Mission and Sensor Web/Testbed Inititives information.

EO-1 Mission

The Earth Observing-1 (EO-1) mission, as part of the New Millennium Program (NMP), developed and validated a number of instrument and spacecraft bus breakthrough technologies designed to enable the development of future earth imaging observatories that will have a significant increase in performance while also having reduced cost and mass.

More specifically, EO-1 has validated a multispectral instrument that is a significant improvement over the Landsat 7 ETM+ instrument; has validated a hyperspectral land imaging instrument and the unique science that can be performed with hyperspectral data; and has validated the ability of a low-spatial/high-spectral resolution imager that can correct systematic errors in the apparent surface reflectances caused by atmospheric effects, primarily water vapor. The breakthrough spacecraft bus technologies that were validated have been made available for future missions.

An important purpose of this website is to make available the information from the EO-1 Final Technology and Science Validation Report. Information from that report is divided up throughout this site in the subpages of the major headings of EO-1 Extended Mission, General Mission and Baseline Mission.

The Extended Mission section of the website describes the expanded public access to EO-1 image data and the transformation of the mission into an advanced development sensor web and testbed activity.

The Baseline Mission and General Mission sections describe the advanced instrument and spacecraft bus technologies; how the technology and science objectives were validated; the validation results and conclusions; what lessons were learned; mission "Firsts"; what Technology and Infusion has occurred; overall mission conclusions; and an extensive list of publications, presentations, and articles spawned by the mission.
