NASA celebrates 40 years of Earth Observation
NASA and the U.S. Geological Survey (USGS) will hold a news conference at 11 a.m. EDT, Monday, July 23, to highlight the accomplishments of the world's longest-running Earth-observing satellite program - Landsat. The briefing will be held at the Newseum at 555 Pennsylvania Ave. NW, Washington, and feature extensive imagery of our changing planet and local U.S. landscapes.
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.
