October 26, 2010 - Landsat Ground Station Operators Working Group (LGSOWG#39)

The Landsat Ground Station Operators Working Group (LGSOWG#39) meeting was held September 27–October 1, 2010, in Rome, Italy. (Read More)

October 15, 2010 - Landsat Processing Down Time

Landsat is installing a suite of new hardware for processing Landsat data on Wednesday, October 20 through Friday, October 22. Newly acquired data and processing of archived data will not be available during the downtime. However, users can continue to download data already processed and submit orders for archived data. Any orders submitted during this time will be queued for processing on October 23. Thank you for your patience.

September 15, 2010 - MSS Data Products now created with LPGS processing system

Beginning September 15, 2010, all MSS data are processed using the LPGS processing system. Previously processed using NLAPS, the newly processed products are now consistent with Landsat ETM+ and TM data products. For more information, visit the MSS product page.

August 25, 2010 - MSS Transition to LPGS Processing

The Landsat project will begin processing MSS data on the Level-1 Product Generation System (LPGS) on September 15, 2010. This is the same system that creates TM & ETM+ products, and there will be increased geometric accuracy in many of the MSS scenes. (Read More)

August 9, 2010 - A Landsat Milestone: Three Million Scenes

USGS EROS has distributed over three million scenes for free via the internet since October 1, 2008.

June 15-17, 2010 - Landsat Science Team Meeting

The Landsat Science Team Meeting was held June 15-17, 2010, in Boise, Idaho. Current and future mission status reports were presented, and Landsat Science Team members provided updates regarding their areas of research.

May 7, 2010 - New Landsat 5 Scheduler

A new Landsat 5 Thematic Mapper (TM) acquisition scheduler was released on May 6, 2010. Similar to that employed by Landsat 7 operations, the new scheduler incorporates daily global cloud forecasts along with seasonal cloud climatology to increase the relative likelihood of acquiring usable imagery. This system has the goal of extending the Landsat 5 Mission while targeting scene opportunities most likely to yield high quality imagery for the global archive.

April 6, 2010 - Modification to Landsat 5’s Acquisition Plan

During Landsat 5’s first 25 years, the Thematic Mapper (TM) sensor acquired data over assigned ground stations regardless of cloud cover or season. This resulted in the collection of significant numbers of TM scenes unsuitable for analysis. In order to maximize the life of the components on the spacecraft, the U.S. Geological Survey’s Flight Operations Team has begun creating a new scheduling tool, designed to avoid acquiring data over areas considered to be too cloudy or off-season.

April 1, 2010 - Former Secretary Udall's Contribution to Earth Imaging

Stewart Udall, Grandfather of the Landsat Mission. With Stewart Udall’s recent passing there have been many powerful obituaries (e.g; Washington Post, March 21, 2010) noting the amazing heritage that Stewart Udall left, particularly in his service to the nation as Secretary of the Department of the Interior (DOI), under the Presidential administrations of John Kennedy and Lyndon Johnson. His contributions to our National Parks and protection of our natural resources were indeed remarkable. (Read More)

March 22 - 26, 2010 - Landsat Technical Working Group (LTWG#19) Meeting

This year's Landsat Technical Working Group (LTWG#19) meeting was held in Phuket, Thailand, March 22–26, 2010. The meeting was jointly organized by the U.S. Geological Survey (USGS) and NASA and was hosted by the Thailand Geo-Informatics and Space Technology Development Agency (GISTDA). Participants from 9 countries, including members of the USGS Landsat and Landsat Data Continuity Mission (LDCM) Projects, represented 14 international ground stations and discussed a wide range of technical topics.

March 1, 2010 - Call for Nominations

The William T. Pecora Award is presented annually to individuals or groups that have made outstanding contributions toward understanding the Earth by means of remote sensing. The Department of the Interior (DOI) and the National Aeronautics and Space Administration (NASA) jointly sponsor the award. (Read More)

February 26, 2010 - Upcoming Joint Agency Commercial Imagery Evaluation (JACIE) Civil Commercial Imagery Evaluation Workshop

The Joint Agency Commercial Imagery Evaluation (JACIE) Civil Commercial Imagery Evaluation Workshop will be held March 16-18, 2010 at the Marriott Fairfax at Fair Oaks, Fairfax, Virginia. (Read More)

February 23, 2010 - Landsat 5 Testing

The Landsat 5 Mission Operations Center will be conducting tests to document the performance of the transmitter. This test could last up to 24 days beginning Tuesday, February 23. The 24-day test will be conducted with fixed latitudes over several primarily northern hemisphere ground stations. The Landsat archive at EROS will be minimally impacted.

February 16, 2010 - New release date for 30-meter thermal

The new Landsat 30-m pixel size for thermal data, mentioned in the February 9, 2010 announcement, will be delayed until February 25, 2010.

February 9, 2010 - Thermal Data to be Resampled to 30 meters

Commercial software has difficulty aligning the 30 meter multispectral data of Landsats 4-7 with the dissimilar thermal pixel sizes. This forces users of the Landsat thermal band to resample data. To remedy this issue, the USGS will set the pixel size for all thermal data at 30 meters as of February 17, 2010. Details are located on page 17 of the Landsat Update Volume 4 Issue 1.

January 28, 2010 - Calibration update to ETM+ thermal band

Effective January 1, 2010, the calibration of the ETM+ thermal band was modified to correct for a lifetime gain error detected by the vicarious calibration teams. Changes were made to the Calibration Parameter File (CPF) to correct a gain error that has been present since the launch of the instrument. (Read More)

January 19-21, 2010 - Landsat Science Team Meeting - 7

The Landsat Science Team Meeting was held January 19-21, 2010, at the Computer History Museum in Mountain View, California. Status reports and perspectives on current and future missions were presented, and a number of Landsat Science Team members provided updates to their areas of research.

January 15, 2010 - Landsat 5 returns to operations

Landsat 5 has continued to downlink data successfully. Data is available for order and download beginning with acquisitions on January 10, 2010.

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.
