Introduction Landsat, a joint program of NASA and the U.S. Geological Survey (USGS), has been an invaluable tool for monitoring changes in Earth’s land surface for over 50 years. Researchers use instruments on Landsat satellites to monitor decades-long trends, including urbanization and agricultural expansion, as well as short-term dynamics, including water use and disaster recovery.

A Tapestry of Tales: 10th Anniversary Reflections from NASA’s OCO-2 Mission
When woven together, the tapestry of experiences of staff and scientists provide the complete picture of OCO-2. Breathe in… Breathe out. This simple rhythm sets the foundation of life on Earth – and it’s a pattern that a NASA satellite has been watching from space for over a decade. On July 2, 2024, NASA’s Orbiting […]
NASA Supercomputers Take on Life Near Greenland’s Most Active Glacier
As Greenland’s ice retreats, it’s fueling tiny ocean organisms. To test why, scientists turned to a computer model out of JPL and MIT that’s been called a laboratory in itself. Runoff from Greenland’s ice sheet is kicking nutrients up from the ocean depths and boosting phytoplankton growth, a new NASA-supported study has found. Reporting in […]
STEM Educators Are Bringing Hands-On NASA Science into Virginia Classrooms
Professional learning experiences are integral to the enhancement of classroom instruction. Teachers, at the forefront of Science, Technology, Engineering, & Mathematics (STEM) education, play a key role in the advancement of STEM learning ecosystems and citizen science. On June 24-25, 2025 – despite a major east coast heat wave – twenty-four educators from eight school […]
NASA-ISRO Satellite Lifts Off to Track Earth’s Changing Surfaces
Carrying an advanced radar system that will produce a dynamic, three-dimensional view of Earth in unprecedented detail, the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite has launched from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, India. Jointly developed by NASA and the Indian Space Research Organisation (ISRO), and a critical part of the United States […]
