NASA satellites and sensors constantly take the pulse of our planet, measuring how Earth changes by the day, season, year, and decade. Researchers and resource managers analyze those measurements and apply them on local and regional scales to better manage things like our food and water supplies, health, safety, land use, and ecosystems. NASA data is also used by other government agencies to help with responses to natural disasters and emergencies around the country and the world.
