The July 23, 1972 launch of the Earth Resources Technology Satellite (ERTS), later renamed Landsat 1, marks the first milepost of the Landsat journey. While the inception of the Landsat program began several years earlier (Goward et al. 2017), that first launch and the subsequent launches of eight more Landsat satellites define a timeline that leads us to celebrate the 50th anniversary of an ongoing satellite program with profound impacts on our observation and understanding of the Earth. Prior histories have addressed technical, programmatic, and scientific aspects of the Landsat program in a more-or-less chronological order (Mack 1990; Goward et al. 2017). Here, we briefly address the cumulative impacts of the Landsat program on key Earth science and environmental topics.
