NASA continues to monitor the planet we call home. Landsat 9, the latest in the series of Landsat Earth-monitoring satellites, is a partnership between NASA and the U.S. Geological Survey that will continue the program’s critical role in monitoring, understanding, and managing the land resources needed to sustain human life. The mission is slated to launch later in 2021.
