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.

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.
Landsat has shown that wildfires and climbing temperatures have caused a 6.7 percent decline in California tree cover since 1985.

Landsat made a solid showing at the annual ALA conference (considered “the world’s biggest library event”) in Washington, D.C. this month.
Landsat allows herders to monitor vast expanses of desert in a way traditional field monitoring can’t support.
This webinar provides an introduction to HLS data, services, and tools and shows you how to find resources to work with the data; visualize, search for, and access the data through NASA Worldview and Earthdata Search; it also demonstrates how to use the Fire Information for Resource Management System (FIRMS) tool to visualize HLS data to monitor fires and floods.
Communicating the technology and science of Landsat has always been a facet of the mission.
