Landsat 9—a partnership between NASA and the U.S. Geological Survey— will continue the Landsat program’s critical role in monitoring, understanding and managing the land resources needed to sustain human life.

Today’s increased rates of global land cover and land use change have profound consequences for weather and climate change, ecosystem function and services, carbon cycling and sequestration, resource management, the national and global economy, human health, and society.

Landsat is the only U.S. satellite system designed and operated to repeatedly observe the global land surface at a moderate scale that shows both natural and human-induced change.

Landsat Data in U.S. archive as of Sept. 2020
The data contributions of each Landsat satellite to the USGS Landsat data archive as of Sept. 30, 2020. For Landsats 4 and 5, the darker color on the bars represents Multispectral Scanner System data and the lighter color is Thematic Mapper data collected by the mission.
See Sept. 2016 and 2017 and 2019 charts for comparison.

Since reducing the risk of a Landsat data gap is a high priority of the U.S. Sustainable Land Imaging Program, Landsat 9 has a design very similar to Landsat 8’s; allowing the Landsat 9 build and launch to be expedited.

Landsat 9, slated for a Mid-2021 launch, will join Landsat 8 in orbit; the satellite orbits will be 8 days out of phase. Landsat 9 will replace Landsat 7 (launched in 1999), taking its place in orbit (8 days out of phase with Landsat 8). The combined Landsat 8 + Landsat 9 revisit time for data collection with be every 8 days, like it currently is for Landsat 8 + Landsat 7.

Landsat 9, like Landsat 8, will have a higher imaging capacity than past Landsats, allowing more valuable data to be added to the Landsat global land archive.

Landsat 8, after collecting data for 7 years, 1.86 million images to the archive—nearly 20% of the total archive holdings—and each day Landsat 8 adds another ~700 new scenes.

Landsat 9, like Landsat 8, will be both radiometrically and geometrically better than earlier generation Landsats
