The data from Landsat 9 is available for anyone to download from the USGS data archive. Launched on Sept. 27, 2021, the new satellite and its instruments went through testing and calibration by the mission team. Now, with both Landsat 9 and Landsat 8 in orbit, there will be high-quality, medium-resolution images of Earth’s landscapes and coastal regions every eight days.

The data from Landsat 9 is available for anyone to download. Now with both Landsat 9 and Landsat 8 in orbit, there will be high-quality, medium-resolution images of Earth’s landscapes and coastal regions every eight days.
Landsat 9 was launched on Sept. 27, 2021, and the mission team started working to test, calibrate, and commission the new satellite and its instruments. One of the commissioning activities was flying Landsat 9 under its sister satellite, Landsat 8, which allowed the team to confirm that the data align as expected.
They also calibrated the instruments through a variety of methods, including tilting Landsat 9’s spacecraft to image the full Moon – a steady source of light to ensure the instruments are detecting light consistently.
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.
