Earth Observing-1 Extended Mission Geological Survey (USGS) and NASA agreed in December 2001 to share responsibility for operating EO-1 on a cost-reimbursable basis as long as customer sales are sufficient to recover flight and ground operations costs. The EO-1 extended mission operates Overview remote sensing instruments: the within constraints imposed by its Advanced Land Imager (ALI), which technology-pioneering origins, but it also From its beginning in November 2000, acquires data in spectral bands and at provides unique and valuable the NASA Earth Observing-1 (EO-1) resolutions similar to Landsat, and capabilities. The spacecraft can acquire mission demonstrated the feasibility and Hyperion, which acquires data in 220 a target scene three times in a 16-day performance of a dozen innovative 10-nanometer-wide bands covering the period. The ALI instrument has sensor, spacecraft, and operational visible, near-, and shortwave-infrared additional spectral coverage and greater technologies. The 1-year mission tested a bands. radiometric dynamic range compared variety of technologies, some of which with the sensors on Landsat 7.
