Connecting Farmers with NASA Data at Commodity Classic
The most common question at the NASA booth at Commodity Classic was, “What does NASA do for agriculture?” The answer was perhaps best summed up by Karen St. Germain, Director of NASA’s Earth Science Division, in a Hyperwall talk delivered at the convention. St. Germain laid out how NASA data could strengthen food security, improve agricultural resilience, and help farmers do what they do best: farm.

A NASA and U.S. Geological Survey (USGS)-supported research and development team, OpenET, is making it easier for farmers and ranchers to manage their water resources with the FARMS tool.
NASA Study Finds Potential Carbon Sink in Boreal Forest Growth
New research led by Landsat 8/9 Project Scientist Chris Neigh used Landsat and ICESat-2 data to investigate how boreal forests growth could sequester carbon.
Spotting Disruptions to Earth’s Vegetation
Using NASA data, researchers can track vegetation changes around the planet, not just in forests but also in grasslands and savannas like the Brazilian Cerrado.
NASA Open Data Turns Science Into Art
Numerous artists have incorporated NASA science data into their work, further engaging the public in science discovery.
Landsat and Earth Science Education: Mapping NASA Earth Data to Next Generation Science Standards
NASA’s Science Activation team has created a graphic to help K-12 teachers find out which NASA Earth Science missions can provide real-world data most relevant to their Next Generation Science-based lessons.
Mapping Grasslands: An Underappreciated Ecosystem
Grasslands tend to get left out of conservation discussion. New research from the World Resources Institute maps how they've changed over the past 20 years.
Understanding Forests After Fire With Landsat and LiDAR
Wildfires have been increasing in frequency and size across North America in recent years. British Columbia is no exception to that trend; more than 4% of the heavily-forested province has burned since 2017. In 2023, Canada saw its worst wildfire season in recorded history. These high intensity fires affect ecosystem health and local economies, as timber is a major industry in BC.
Urban Heat in the Lower Mekong Delta
Looking at urban heat islands, researchers found that changing trends in vegetation influence land surface temperature in the Lower Mekong Delta cities.
Virginia Norwood Recognized by National Inventors Hall of Fame
Virginia Norwood is being posthumously recognized for designing the Landsat multispectral scanner system.
