November 20, 2013 - New Ground Control Available Soon for Select Path/Rows

New Ground Control Points (GCPs) will become available for a number of WRS-1 and WRS-2 path/rows on December 5, 2013. This will affect Landsat Multispectral Scanner (MSS), Thematic Mapper (TM), and Enhanced Thematic Mapper Plus (ETM+) data. (Read More)

November 15, 2013 - Changes in World’s Forests Portrayed Using Landsat 7 Data

A new study discussing the importance of forest ecosystems has been published in the November issue of Science magazine. Thomas Loveland, chief scientist at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, S.D., assisted in the unparalleled survey of over 650,000 Landsat 7 scenes to develop the most detailed and complete assessment of global forest dynamics available.

November 14, 2013 - Landsat 8 Reprocessing Rescheduled

The previously-planned reprocessing effort of all Landsat 8 data in the USGS archive will begin in early 2014. During this time, all Landsat 8 data held in the USGS archive will be purged and reprocessed using updated calibration parameters for both OLI and TIRS data.

Details about the changes to the data are available in the November 14, 2013 Calibration Notice.   

October 28, 2013 - Upcoming Landsat 8 Reprocessing

Within the upcoming weeks, all Landsat 8 data held in the USGS archive will be reprocessed using updated calibration parameters for OLI and TIRS data. During this time, all online products will be purged and the online inventory will be re-populated. Details about the changes to the data are available in the October 25, 2013 Calibration Notice.

October 17, 2013 - Landsat Data Processing Resumes

Processing has resumed for Landsat 8 and Landsat 7 data acquired from October 1, 2013 to October 17, 2013. Scenes will become available for download from EarthExplorer and GloVis as processing is completed.

September 30, 2013 - Operations Update

In the event that U.S. Federal agencies are confronted with a lapse in appropriations on October 1, 2013, the Landsat 7 and 8 satellites will continue mission essential operations. The satellites will collect and downlink data to the Landsat Ground Network (LGN) and International Cooperators. (Read More)

September 27, 2013 - Landsat 7 Thermal Band Calibration Update

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 calibration teams detected a bias error of 0.036 watts per square meter steradian micron  (W/(m2 sr µm)) that causes overestimation of top-of-atmosphere temperatures by approximately 0.26 Kelvin (K) at 300K. Calibration parameters within the Calibration Parameter File (CPF) have been adjusted to correct for this bias error. (Read More)

September 27, 2013 - CPF update for Offset Following Safehold

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 264 (September 21, 2013). (Read More)

September 24, 2013 - Landsat 8 safehold update

On Saturday September 21, 2013, the Landsat 8 flight operations team successfully recovered the Landsat 8 observatory from ‘safehold’ and resumed the collection of science data at 17:07:03 GMT (11:07:03 CDT). Imaging resumed on WRS-2 Path 14 Row 247.

Investigation into the cause for the observatory going into safehold is ongoing and updates will be posted when additional information is available.

September 19, 2013 - Landsat 8 in Safehold

On September 19, 2013 at 15:38 CDT, Landsat 8 entered a ‘safehold’ condition that has suspended the collection of science data. The Landsat 8 observatory is healthy, and no issues are expected during the recovery process being executed, which will return the satellite to nominal operations. Full recovery is expected in the next few days. More information will be posted as recovery progresses.

September 16, 2013 - Notice of Landsat 8 Data Reprocessing

The Landsat project has determined that a bias correction needs to be applied to Landsat 8 thermal infrared sensor (TIRS) band 10 (10.3 - 11.3 um) data. The USGS plans to reprocess all Landsat 8 data that have been acquired to date with the updated bias in the near future. More details about data changes and the schedule will be posted on the web site within the upcoming weeks.

July 16, 2013 - Landsat 8 QA Data Tool Available

The USGS now offers a tool that accurately translates and interprets Landsat 8 OLI Quality Assessment (QA) bits, within the Landsat LDOPE Toolbelt. (Read More)

July 8, 2013 - Old data being made newly available

As part of the Landsat Global Archive Consolidation effort, the first international Multi-Spectral Scanner (MSS) data from Canada has been added to the archive! MSS data, captured by the first Landsat missions, are often the most difficult to ingest and process, but yet can be the most valuable for studies using time series. The Canadian Centre of Remote Sensing contributed the data months ago, but the software to ingest that data successfully was just released in late June.

June 12, 2013 - Landsat Data Downloads Unavailable

Landsat data downloads will be unavailable from 7:00 am to 7:30 am on Thursday, June 13, 2013.

June 5, 2013 - Final command sent to Landsat 5

For over 29 years, commands have been sent to Landsat 5 for acquisitions, orbital maneuvers, to fix problems, and even to avoid space junk. Today at 11:34 EDT, the final command was sent to Landsat 5, to turn her solar array away from the sun, essentially ending further power to the onboard computer. (Read More)

May 30, 2013 - Landsat 8 Data Available!

NASA has declared that the Landsat Data Continuity Mission's on-orbit checkout is complete, and it has been renamed Landsat 8 with the hand-off of operations to the USGS! Starting at 1 pm CT on May 30, data collected by the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS) onboard the spacecraft will be available to download from EarthExplorer, and the LandsatLook Viewer.

May 17, 2013 - Surface reflectance is now available

Surface reflectance is now available as a Landsat climate data record (CDR) product through EarthExplorer.

These products are generated on-demand from Landsat 5 TM and Landsat 7 ETM+ data and are also available for the Global Land Survey 2000, 2005, and 2010 collections.

May 15, 2013 - Fly with LDCM!

On April 19, 2013, the Landsat Data Continuity Mission passed over one long swath from Russia to southern Africa. Our mission partners at NASA crafted a beautiful fly-over that is a must-see!

About

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
