NASA’s fleet of satellites has been watching over Earth for more than half a century, collecting valuable data about the crops that make up our food supply and the water it takes to grow them. This wealth of information allows scientists to monitor farmland—tracking the overall food supply, where specific crops are grown, and how much water it takes to grow them with data from the Landsat satellites and others. And with that data, farmers can find new ways to grow more crops with less water.

The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey (USGS). Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth’s changing landscapes for the benefit of all.
