An advanced photodetector camera that traces its heritage to one now flying on Landsat 8 is being studied as a potential payload on a conceptual satellite (CapSat) system purposely designed to take advantage of the expected boom in [...]
NASA moved forward with plans to execute the ambitious Restore-L mission, an endeavor to launch a robotic spacecraft in 2020 to refuel a live satellite. The current candidate client for this venture is USGS-operated Landsat 7.
NASA has awarded a sole source contract to Ball Aerospace and Technology Corporation of Boulder, Colorado, for the Thermal Infrared Sensor-2 (TIRS-2) instrument Cryocooler for Landsat 9.
Toward the end of April, reprocessing efforts will begin for Landsat 8 OLI/TIRS scenes acquired from January 1 to March 31, along with data acquired during April, to create nominal Level-1 products containing valid TIRS data.
As of Feb. 12, 2016, many of the Landsat 8 scenes acquired from October to December 2015 have been reprocessed into nominal Level-1 products containing valid TIRS data and are available for download, and can also be submitted for higher-level [...]
Landsat 8 Thermal Infrared Sensor (TIRS) data continue to be collected with the scene select mirror encoder electronics disabled (mode 0). While in this mode, the TIRS line of sight model (LOS) will be regularly updated and modifications are [...]
The USGS has begun production of higher-level (more highly processed) Landsat data products to help advance land surface change studies. One such product is Landsat surface reflectance data.
After extensive investigation and testing, the decision has been made to switch the TIRS Mechanism Control Electronics from the primary to redundant side on Monday, March 2, 2015.

On December 19 the TIRS instrument on Landsat 8 was reconfigured due to detection of anomalous current levels associated with the scene select mirror encoder electronics. Since that time substantial testing has been conducted to isolate the root [...]
Shortly after the launch of Landsat 8, the calibration team noticed something strange: bright and dark stripes, or “banding” was showing up across certain images collected by the satellite’s Thermal Infrared Sensor (TIRS). Prelaunch testing of [...]
The Landsat calibration team published a number of papers in the SPIE Conference Volume 9218: Earth Observing Systems XIX. Our calibration team (or cal team) is a group of scientists and engineers who work together to ensure the scientific [...]
On public land in the Ivanpah Valley near the California/Nevada border, the world’s largest concentrated solar thermal plant sprawls across the desert landscape. Just on the other side of Interstate 15 (the long straight diagonal line) is the [...]
Under the National Land Imaging Requirements (NLIR) Project, the U.S. Geological Survey (USGS) is developing a functional capability to obtain, characterize, manage, maintain and prioritize all Earth observing (EO) land remote sensing user [...]
Landsat helps scientists comprehend what changes have occurred on Earth’s land surfaces. Since 1972, Landsat satellites have been amassing information about the land cover of our planet and land cover, as obscure as it may sound, is important [...]
Landsat 8 was built to do something none of its predecessors had done before: look at the Moon. You may ask why an Earth-observing mission would want to image Earth’s natural orbiting celestial body. Well, it all goes back to getting good data [...]
Beginning February 3, 2014, all Landsat 8 data held in the USGS archives will be reprocessed. All Landsat 8 scenes will be removed from the online cache at this time and the data will then be reprocessed starting with the most recent [...]
On December 4, the U.S. Geological Survey (USGS) and NASA will host an event in which leadership from both agencies will provide details about how user needs will be assessed to help inform NASA’s Sustainable Land Imaging Program.
The majority of the radiometric calibration changes indicated in the October 25, 2013 calibration notice have been deferred to early-2014, to coincide with a software update for the Landsat Product Generation System (LPGS). Therefore, [...]
NASA and Amazon Web Services Inc. (AWS) of Seattle, Wash., are making a large collection of NASA climate and Earth science satellite data available to research and educational users through the AWS cloud.
In the near future, calibration changes will be made that will affect the Thermal Infrared Sensor (TIRS) Band 10 and all of the Operational Land Imager (OLI) bands onboard Landsat 8.
Within the next several weeks, all Landsat 8 data that have been acquired since achieving WRS-2 operational orbit will be reprocessed using updated calibration parameters for OLI and TIRS data. During this time, all online products will be [...]
Effective October 1, 2013, the calibration of the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) Band 6 will be updated to correct a bias error that has been present in all thermal data since the last calibration update in 2010. Vicarious [...]
On September 19, 2013 (DOY 262) at approximately 20:08 UTC, Landsat 8 experienced an unplanned transition to safe hold following an attitude control anomaly. Precision attitude control was recovered and imaging operations resumed on day of year [...]
Thousands of never-before-seen data products from the U.S. Landsat satellites acquired over 30 years have been released for online access. In addition, the newest data over Europe from the latest satellite in the series, Landsat 8, are now [...]
Landsat 8 officially began normal operations on May 30, 2013, when the leadership for satellite operations transferred from NASA to the U.S. Geological Survey. With the hand-off, the name of the satellite changed from the Landsat Data Continuity [...]
