The Mt. Kilimanjaro snowcap is seen in this January 2017 image taken by the Pathfinder Earth Observing-1 (EO-1) satellite just months before the mission ended. Originally designed to last one year, EO-1 spent 17 years in orbit providing a variety of Earth data, including observations of forest cover, crops, coastal waters and aerosols. One of EO-1’s most important achievements was to validate the Advanced Land Imager (ALI), which influenced the development of later Earth-observing technologies—including the Operational Land Imager (OLI) on Landsat 8, a NASAU.
