Abstract	n The Earth Observing 1 (EO-1) satellite, developed under NASA’s New Millennium Program, was successfully launched on 21 November 2000 from Vandenberg Air Force Base, California. The primary land-sensing instrument for this mission is the Advanced Land Imager (ALI), designed and developed by Lincoln Laboratory. ALI collected its first image just five days after launch. Although EO-1 was intended to be a one-year technology-validation mission, ALI still continues to produce valuable science data after five years in orbit. Lincoln Laboratory personnel have evaluated in detail the technical performance of ALI. A team of experienced earth scientists assembled by NASA has also assessed the quality of the science products obtained from ALI and compared the results directly with those obtained from the Enhanced Thematic Mapper Plus sensor on Landsat 7. The results demonstrate that ALI has superior performance in resolution, sensitivity, and dynamic range. These investigations have provided critical input for the design and implementation of next-generation Landsat imagers. This article summarizes the initial ALI program development and Lincoln Laboratory’s role in the mission formulation. We also give an overview of ALI instrument design and performance. Finally, we discuss the relevance of ALI to future land remote sensing instruments.
