In cooperation with the U.S. Department of the Interior (DOI) and its science agency, USGS, NASA launched the first Landsat satellite July 23, 1972. The resulting 40-year archive of Earth observations from the Landsat fleet forms an impartial, comprehensive, and easily accessed register of human and natural changes on the land. This information supports the improvement of human and environmental health, biodiversity, energy and water management, urban planning, disaster recovery and crop monitoring.
During the briefing, NASA and USGS will announce the 10 most significant images from the Landsat record, the U.S. regions selected for the "My American Landscape" contest showing local environmental changes, and the top five Landsat "Earth As Art" images selected in an online poll.
