At the USGS EROS Center, we study land change and produce land change data products used by researchers, resource managers, and policy makers across the nation and around the world. We also operate the Landsat satellite program with NASA, and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images.

Landsat 9 Serves as Backbone of Efforts to Reduce Deforestation and Forest Degradation

The Landsat program has long been a powerful partner in the effort to manage and reduce carbon emissions worldwide.

The launch of Landsat 9 and its extension of the program’s nearly 50-year record of Earth surface change will help ensure the stability of those efforts, according to officials working with developing nations to monitor deforestation and forest degradation.

Underfly Positions Landsat 9 Below Landsat 8 for Simultaneous Scenes

The newly launched Landsat 9 is experiencing a once-in-a-mission lifetime event where its orbit is directly below Landsat 8 for an “underfly.” For several days in the middle of November, the pair of Earth-observing satellites are flying together, collecting data at the same time for the same sites and requiring simultaneous downlinking to global ground station antennas.
