For 25 years, NASA’s Flagship Earth Observing System satellite, Terra, has collected daily morning Earth observations using five different instruments: ASTER, CERES, MISR, MODIS, and MOPITT. Collectively, these observations establish a robust satellite record of global scientific processes, allowing us to track changes in temperature, glaciers, clouds, vegetation, land-use, air quality, and natural hazards like hurricanes, wildfires, and volcanic eruptions.
Originally designed to last only 6 years, Terra continues to deliver near real-time daily data used by emergency managers, researchers, and modelers over a quarter-of-a-century later.

25 Years of Terra @ 2024 AGU Annual Meeting
The week prior to the GSFC Visitor’s Center event, several members of the Terra mission community presented on 25 Years of Terra at the 2024 Annual Meeting of the American Geophysical Union in Washington, D.C.
