A long string of Earth-observing orbiters began with NASA's Earth Resources Technology Satellite (ERTS). Launched in July 1972, it was the first satellite explicitly designed to study our planet. Three years later, the satellite was renamed Landsat 1. Outlasting its one-year design, Landsat 1 retired in January 1978.
