​September 13, 2017 - Landsat 7 Solid State Recorder Anomaly

Early morning September 13, 2017, the Landsat 7 Solid State Recorder (SSR) experienced an anomaly. The Flight Operations Team (FOT) initial analysis of telemetry indicated what is referred to as an "SSR choke anomaly" where the SSR locks up. This condition has occurred multiple times over the past several years. (Read more)

August 25, 2017 - Landsat 7 Reaches Peak Outer Boundary

Landsat 7 recently reached its peak outermost boundary of 10:14:58 Mean Local Time (MLT) on August 11, 2017, since the final Delta-Inclination (Delta-I) maneuver took place on February 7, 2017. (Read More)

Watch Landsat LIVE!

A recent release of the EarthNow! Landsat Image Viewer displays imagery in near real-time as Landsat 7 and Landsat 8 orbit the Earth. Along with the near real-time video stream, EarthNow! also replays acquisition recordings from a list of previous Landsat overpasses. (Read More)

March 16, 2017 – Elevation discrepancy prompts reprocessing of Landsat 7 Antarctic data

During Collection 1 Level-1 data processing of Landsat 7 ETM+ scenes covering Antarctica, it was discovered that about 2,700 scenes were processed using incorrect elevation data. While acquisition dates vary, the majority of scenes affected were acquired between January 2000 and January 2001. During the week of March 20, 2017, these data will be reprocessed with correct elevation information and will be repopulated on EarthExplorer. This file lists the affected scenes that will be reprocessed.

May 17, 2016 - Landsat 7, Landsat 5 Collection 1 Level-1 Sample Data Available

Collection 1 Level-1 sample data products for Landsat 7 and Landsat 5 are now available. Users are encouraged to analyze these samples and contact User Services with any questions or feedback.

September 28, 2015 - Upcoming Landsat 7 Maneuver, No Data To be Acquired

Landsat 7 inclination maneuver (delta i) operations for 2015 will begin on Tuesday September 29, 2015 (DOY 272). No Landsat 7 data will be acquired starting at 12:00 UTC (7:00 am CDT) on DOY 272, until approximately 04:30 UTC (11:30 pm CDT) on October 1, 2015 (DOY 274). We apologize for any inconvenience this may cause.

March 20, 2015 - Attention Landsat Data Users

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.

Thank you for your patience in this matter.

February 27, 2015 - Upcoming Landsat data changes

A number of changes affecting Landsat data are planned to take place during the Spring of 2015. The Landsat Update published today provides updated information about these planned changes.

February 9, 2015 - Upcoming Landsat 7 Data Unavailable During Orbit Maneuver

The Landsat 7 satellite will be conducting an orbit maintenance maneuver beginning at 15:00 UTC (9:00 am CT) Tuesday, February 10, 2015 (DOY41), which will cause an interruption of Landsat 7 data products. The maneuver will be complete and operations will return to nominal by 21:15 UTC (3:15 pm CT) on Wednesday, February 11, 2015 (DOY42). No Landsat 7 science data will be acquired during the maneuver.

January 28, 2015 - Important Information about Upcoming Landsat Data Processing Changes

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.
