Instrument Technology Overview

The Earth Observing-1 (EO-1) mission is flying three advanced technology verification land imaging instruments. They are the first Earth-observing instruments to be flown under NASA’s New Millennium Program. The three instruments are the Advanced Land Imager (ALI), the Hyperion hyperspectral imager, and the Linear Etalon Imaging Spectrometer Array (LEISA) Atmospheric Corrector (LAC). These instruments incorporate revolutionary land imaging technologies that will enable future Landsat and Earth observing missions to more accurately classify and map land utilization globally.
