Landsat scenes downlinked directly to the USGS EROS archive are available for download or processing within about 12-24 hours after downlink.
Landsat 8 collects approximately 400 scenes per day, in accordance with the Long Term Acquisition Plan (LTAP-8). The LTAP directs the acquisition of Landsat 8 scenes, using parameters such as seasonality, land definition, historical cloud cover, gain settings, and sun angle.
NOTE: The "Landsat 8 acquisitions planned today" report is currently incomplete, and only represents a portion of the Landsat 8 acquisition schedule. Complete schedules will be posted during the summer of 2013. Images over the conterminous United States are acquired at every opportunity.
NOTE: Some acquisitions were not made due to testing of either or both the Operational Land Imager (OLI) or Thermal Infrared Sensor (TIRS) instruments. This list shows the affected paths and dates.
Landsat 7 collects approximately 350 scenes per day, in accordance with the Long Term Acquisition Plan (LTAP). The LTAP directs the acquisition of Landsat 7 scenes, using parameters such as seasonality, land definition, historical cloud cover, gain settings, and sun angle. Scenes downlinked to other ground receiving stations may become available in the USGS archive, but the International Ground Station that collects the data is the primary distributor.
Landsat 5 acquisitions have ceased, effective December 2012. Decommissiong details can be found on http://landsat.usgs.gov/L5_Decommission.php.Landsat 5 acquisitions archive
Landsat Acquisitions Limited Due to Sun Angle
These maps show the areas of Earth that are imaged throughout the year, and also the areas of land that are not collected due to the sun angle.
