US: NASA’s Landsat programme completed 40 years of earth observation. The group of remote sensing satellites have been gathering specialised data that can produce incredible digital images for almost 40 years. NASA and the U.S. Geological Survey (USGS) held a news conference highlighting the accomplishments of the world’s longest-running Earth-observing satellite programme – Landsat.
In cooperation with the U.S. Department of the Interior (DOI) and its science agency, USGS, NASA launched the first Landsat satellite on 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.
