“On this day in 2008, the USGS announced their plan to ‘open’ the USGS EROS Landsat archives, making all Landsat data available to download at no charge, to all users worldwide. Fifteen years later, in the “Year of Open Science”, Landsat continues to lead how Earth Observation data is utilized, and how Landsat data is used to support science and research efforts. …

The graph below displays number of Landsat-related citations (orange line) and the cost per scene (blue line) from 1970 to 2022. As expected, citations increased greatly after the data became freely available starting in December 2008….”

“The U.S. Geological Survey will make Landsat 9 data available from the Landsat archive beginning February 10, 2022. …

At this time, USGS Landsat 9 Collection 2 Level-1 and Level-2 data will be made available for?download from EarthExplorer, Machine to Machine (M2M), and LandsatLook. Initially, USGS will provide only full-bundle downloads. USGS will provide single band downloads and browse images, and Landsat 9 Collection 2 U.S. Analysis Ready Data shortly thereafter. Commercial cloud data distribution will take 3-5 days to reach full capacity. 

 

The recently deployed Landsat 9 satellite passed its post-launch assessment review and is now operational. This milestone marks the beginning of the satellite’s mission to extend Landsat’s unparalleled, 50-year record of imaging Earth’s land surfaces, surface waters, and coastal regions from space. Landsat 9 launched September 27, 2021, from Vandenberg Space Force Base in California. The satellite carries two science instruments, the Operational Land Imager 2 (OLI-2) and the Thermal Infrared Sensor 2 (TIRS-2). The OLI–2 captures observations of the Earth’s surface in visible, near-infrared, and shortwave-infrared bands, and TIRS-2 measures thermal infrared radiation, or heat, emitted from the Earth’s surface. …”
