September 14, 2017 – Landsat 7 Anomaly Resolution

Engineers have successfully completed recovery efforts of the Landsat 7 Solid State Recorder (SSR) anomaly that occurred on September 13, 2017. The satellite resumed nominal imaging operation as of September 13 (DOY256) at 22:09 UTC (5:09 pm CST) and data are available to download from EarthExplorer, GloVis, or the LandsatLook Viewer.

​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)

July 21, 2017 - Celebrating Forty-Five Years of Landsat

On July, 23 2017, the Landsat Program will celebrate forty-five years of continuous Earth observation. NASA — working in cooperation with the U.S. Department of the Interior (DOI) and its science agency, the USGS — launched the first Landsat satellite (originally named Earth Resources Technology Satellite 1) on July 23, 1972.

Land Remote Sensing Image Collections

Wildfires Devastate California Wine Country
Residents had little warning when wildfires that ignited late Sunday night, October 8, 2017, were fanned by wind gusts of 50 miles per hour and blasted across California's wine country.
Pine Island Glacier's Newest Iceberg
Pine Island Glacier in Antarctica has snapped off its share of icebergs in recent years. The frequency of noteworthy breaks is evidence that the ice shelf is becoming increasingly fragile.
Puerto Rico after Hurricane Maria
Hurricane Maria swept across Puerto Rico on September 20, 2017, as a Category 4 hurricane and the fifth strongest storm ever to hit the United States.
Irma Churns Up Sediment in the Florida Keys
Hurricane Irma crossed the Florida Keys the morning of September 10, 2017, as a Category 4 hurricane with winds of 130 miles per hour.
Hurricane Irma Slams Barbuda
Hurricane Irma was a Category 5 superstorm when it lashed the Caribbean island of Barbuda on September 6, 2017.
Hurricane Harvey Flooding
Extensive flooding inundated the Gulf Coast of Texas after Hurricane Harvey made landfall as a Category 4 hurricane on August 25, 2017.
Gypsy Moth Infestation Continues in New England
A large outbreak of gypsy moth (Lymantria dispar) caterpillars attacked the hardwood forests of the northeastern United States in 2016.
Fire in Greenland
It may seem surprising that wildfires burn in Greenland, a huge island of ice and glaciers.
Batagaika Crater and the Megaslump
An increasingly large gash has opened up in northern Russia's Siberian tundra. During the past few decades, warmer summers and shorter winters have caused permafrost in this region to thaw, which then allows the warmed soils on slopes to slump and erode.
Iceberg Separates from Larsen C Ice Shelf
Around July 10–12, 2017, in the middle of the long, dark Antarctic winter, a rift in the Larsen C Ice Shelf broke through the last few miles of ice to the Weddell Sea and formed a new iceberg.

“Measuring the past contributes to our understanding of the long-term consequences of our past economic and societal choices, and contributes to more informed management decisions in the future.”

Jean-François Pekel, who used 3 million Landsat images to make global surface water, Smithsonian Magazine, Dec 9, 2016

“What we’re able to do now is track the flow of the world’s ice from pole to pole and on every continent.”

Ted Scambos,, a glaciologist at the National Snow and Ice Data Center, talking about the Landsat 8-based GoLIVE project, Climate Central, Dec 21, 2016

“We cannot do this project if the Landsat program doesn’t deliver this open data to the scientific community… We are benefiting from these long-term investments now.”

Lilian Pintea, VP of conservation science, Jane Goodall Institute

“From a valuation standpoint, Landsat is an extremely valuable public good just in its direct use—let alone the economic value of all the indirect uses built on the direct data.”

John Loomis, an economist at Colorado State University, Landsat Benefited U.S. Economy by $1.8 Billion in 2011, Aug 30, 2015

“The Landsat archive holds great potential for studying the processes behind the Greenland Ice Sheet’s response to our changing climate over multi-decadal time scales. It is essential that this record be exploited over other areas of the Greenland Ice Sheet.”

Noel Gourmelen, Despite Warming, Landsat Reveals Decadal Slowdowns on Greenland Ice Sheet, Oct 28, 2015

"We are now beginning to see that the combination of high performance computing, data storage facilities, data preparation techniques, and advanced systems can materially accelerate the value of Landsat data."

Dr. Suzette Kimball, acting Director of the USGS, A New Era of Space Collaboration between Australia and U.S., Jun 18, 2015

“...the time is now right and urgent to apply space technology towards the solution of many pressing natural resources problems being compounded by population and industrial growth.”

Stewart L. Udall, Secretary of the Interior (1966)

“The economic value of just one year of Landsat data far exceeds the multi-year total cost of building, launching, and managing Landsat satellites and sensors.”

Landsat Seen as Stunning Return on Public Investment, Jan 14, 2015, USGS press release

“The value of Landsat data is internationally recognized as indispensable to science, natural resource management, commerce, security, foreign policy, agriculture, and education.”

National Geospatial Advisory Committee, Landsat Advisory Group, Statement on Landsat Data Use and Charges, Sept 18, 2012

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.
