This February marks the 10th anniversary of the launch of Landsat 8, launched by NASA in 2013 and operated by the US Geological Survey.
An international team of researchers has combined satellite imagery and climate and ocean records to obtain the most detailed understanding yet of how the West Antarctic Ice Sheet – which contains enough ice to raise global sea level by 3.3 metres – is responding to climate change.
Landsat was part of over 400 presentations at the AGU 2022 Fall Meeting this year in Chicago.
Virginia Norwood was recognized by AGS for her development of the first Landsat sensor and Karen Seto was recognized for her urban growth research which often relies on the long Landsat data archive.
With a trio of smaller satellites that can each detect 26 wavelengths of light and thermal energy, the Landsat Next mission is expected to look very different from its predecessors that have been observing Earth for 50 years.
NASA Harvest gathered agricultural remote sensing experts to discuss how Landsat fundamentally transformed agricultural monitoring over the last half century.
The world has lost 561 square miles (1,453 square kilometers) of salt marshes over the past 20 years.
A U.S. Senate subcommittee hearing titled “Landsat at 50 & the Future of U.S. Satellite-based Earth Observation: took place on Thursday, Dec. 1, 2022.
Satellites offer a wealth of information pertinent for water and food security. Landsat has long been a foundational piece of the “Space for Ag” initiative.
New research uses Landsat observations and advanced computing to chronicle wetlands lost (and found) around the globe.
Thirty-meter Landsat 8 and 9 data have been added to NASA’s Fire Information for Resource Management System (FIRMS).
On Saturday, October 15, the Visitors Center at NASA’s Goddard Space Flight center presented an audio/visual event in celebration of Landsat’s 50th anniversary.
Nestled in the science-based information that park rangers share with visitors to Glacier Bay National Park and Preserve are insights from Landsat satellites and NASA climate scientists.
UCONN remote sensing experts used Harmonized Landsat Sentinel-2 imagery to quickly assess damage caused by the storm’s aftermath, providing spatially-relevant situational awareness that could aid rescue efforts.
Airborne Snow Observatories, Inc. uses higher-resolution snow cover data from Landsat to update their model snow cover.
More frequent satellite observations, such as those of the Harmonized Landsat Sentinel-2 (HLS) dataset, are needed to fully capture flood dynamics in regions experiencing short-lived, ephemeral flooding.
OSAM-1 Lead Systems Engineer Wendy Morgenstern discusses NASA’s On-orbit Servicing, Assembly, and Manufacturing 1 mission to robotically refuel Landsat 7, a satellite that wasn’t designed to be serviced.
Data collected by citizen scientists like you helps land cover scientists evaluate the quality of the maps produced from satellites like Landsat.
I use Landsat data alongside other satellite and field data to map where and when crops like wheat are growing, to analyze different management practices including when crops are planted and harvested, to assess crop health and to forecast end of season yields.
NASA transferred ownership and operational control of the Landsat 9 satellite to the U.S. Geological Survey (USGS) in a ceremony in Sioux Falls, South Dakota on on Thursday, Aug. 11, 2022.
We’ve processed more than 224,000 Landsat images of the boreal forest, from 1984 through 2020, all to understand changes in tree-cover extent.
In my Ph.D. research at McGill University in Canada, I used Landsat data to map fire progressions for Canadian wildfires.
The 22nd William T. Pecora Memorial Remote Sensing Symposium (Pecora 22) will convene in Denver, Colorado, USA from October 23 – 28, 2022, and will focus on all aspects of Earth observation, spanning scientific discoveries to operational applications, and from sensors to decisions.
After 50 years of Landsat, discovery of new commercial and scientific uses is only accelerating.
July 23, 2022, was designated as Landsaturday by the U.S. Senate in recognition of the 50th anniversary of the Landsat Program.
Virginia T. Norwood, known as the person who could solve impossible problems, played a crucial role in the development of the first space-based multispectral scanner instrument that flew on Landsat 1 and made the mission a success.
I use Landsat to explore wetland and aquatic ecosystem dynamics over time, studying how they may vary in a changing climate. Biotic and abiotic, everything on Earth has its own connection.
I use Landsat data as part of a joint U.S. Department of Agriculture/NASA effort to inventory all forest lands in interior Alaska.
Since its debut, Landsat has amassed over 10 million images. These images, also called scenes, show current snapshots of land and coasts, but pair with images of years past and they also reveal changes through time – glaciers slowly disappearing, or urban spaces sprawling across the landscape.
I worked at Goddard Space Flight Center for 43 years. A great deal of my career was spent engaged in the Landsat program.
Landsat satellites have been reliably returning images of Earth’s land surface for fifty years, providing novel insights about the planet we call home.
