On March 1, 1984, Landsat 5 launched from Vandenberg Air Force Base, California. Landsat 5 was designed and built at the same time as Landsat 4 and carried the Multispectral Scanner System (MSS) and the Thematic Mapper (TM) instruments. (Read More)
The Landsat 1-7 browse and full resolution browse products for MSS, TM and ETM+ data need to be reprocessed to correct a recent problem. The issue should be resolved by March 23, 2015. This Landsat browse problem does not affect the quality or usability of other Landsat data downloads.
During Spring 2015, significant changes to Landsat products will improve the consistency of Landsat 4-8 data records. These changes will enhance data usability. The planned changes, potential impacts, and benefits are summarized on the recently published Landsat Update.
Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) version 2.2.1 was implemented on January 21, 2015 and includes the correction of two issues introduced by LEDAPS 2.2.0 on December 23, 2014: (Read More)
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)
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)
The workhorse of the Landsat 5 mission was the Thematic Mapper (TM) instrument. In November of 2011, the TM failed, and the MultiSpectral Scanner (MSS) instrument was brought back online a few months later. The MSS had not acquired data for over a decade, due to the loss of Band 4 (and the continued success of the TM). While the MSS was acquiring data, the ground station was crafting new capabilities to ingest the raw instrument data. The data have been successfully ingested and are available from EarthExplorer.
Landsat 5 successfully set the new Guinness World Records title for 'Longest-operating Earth observation satellite’ as stated in an e-mail from Guinness World Records sent to NASA Goddard Space Flight Center in Greenbelt, Maryland. Outliving its three-year design life, Landsat 5 delivered high-quality, global data of Earth's land surface for 28 years and 10 months.
Today, the USGS announced that Landsat 5 will be decommissioned over the coming months, bringing to a close the longest-operating Earth observing satellite mission in history. See this page for Landsat 5's amazing service and legacy!
All Landsat Thematic Mapper (TM) scenes were removed from downloadable state on October 29, 2012, to resolve issues with thermal band 6 processing. Any previously placed requests for TM data will need to be resubmitted for processing. We apologize for this inconvenience. Please Contact Us with any questions or concerns about this.
Issues have been identified with thermal band 6 of Landsat Thematic Mapper processed data, due to the Calibration Parameter File (CPF) updates implemented on October 1, 2012. We are working to resolve this issue as quickly as possible. Please Contact Us with any questions or concerns about this.
Once a quarter, the radiometry experts on the Landsat team craft a new Calibration Parameter File (CPF), which is then incorporated into processing new and archived data. For Landsat 5 TM products created on or after 1 October, the update will improve radiometric accuracy and will significantly reduce or eliminate residual banding and striping. See the Calibration Notices webpage for more information.
After a silent winter, the USGS turned on the Landsat 5 Thematic Mapper (TM) in late April to determine the state of the electronics problem that suspended operations in November, 2011. Unfortunately, several alternate methods of acquisitions did not alleviate the problem, which severely limits any further acquisitions with the TM. (Read More)
Plans to test the Landsat 5 Thematic Mapper downlink begin today, April 25, 2012. Data may be visible on the EarthNow! during testing. However, the data will not be available for download by users until completion of analysis and calibration.
Landsat 5 recently captured and downlinked Multispectral Scanner (MSS) images for the first time in over a decade. An MSS sensor first flew on Landsat 1 in 1972 and was aboard each of the Landsats 1-5. The MSS was powered down on Landsat 5 in the late 1990's, but the USGS recently turned on the MSS to determine the current state of the sensor. (Read More)
Landsat 5 imaging was suspended in November 2011 when a vital transmission component showed signs of imminent failure. The Flight Operations Team continues to explore options, which include alternate operating procedures for the Thematic Mapper and evaluation of the other sensor onboard, the Multispectral Scanner. More details can be found on this NASA webpage.
