- Terra | The EOS Flagship
Update on Terra’s New Orbit: Since 2020, Terra has been drifting to an earlier equator crossing time, and in October 2022 was lowered by ~5km in altitude These changes in orbit did not reduce the data quality of Terra products, and only created minor changes to orbital repeat time and swath width (for some instruments)
- Terra Instruments
Terra collects data about the Earth’s bio-geochemical and energy systems using five sensors that observe the atmosphere, land surface, oceans, snow and ice, and energy budget Each sensor has unique features that enable scientists to meet a wide range of science objectives The five Terra onboard
- 2025 | Terra
Terra, which carries five instruments, launched in December 1999 on a six-year mission designed to study the planet’s land, ocean, atmosphere and biosphere simultaneously as the flagship mission of NASA’s Earth Observing system Terra is a partnership between the United States, Canada and Japan
- Data - Terra
Terra’s five instruments produce 83 core data products which are distributed through the Land Processes Distributed Active Archive Center (LPDAAC), the Atmospheric Science Data Center (ASDC), Ocean Color Web, Level 1 and Atmosphere Archive and Distribution System, and the National Snow and Ice Data Center (NSIDC)
- Mission - Terra
Terra observations reveal humanity’s impact on the planet and provide crucial data about natural hazards like fire and volcanoes See Terra science Terra is an international mission carrying instruments from the United States, Japan, and Canada

Terra will also continue collecting data after an orbit lowering maneuver planned for Fall 2022 The maneuver upholds agreements to ensure Terra is a safe distance from the other missions in the 705-km Earth Observing Satellite Constellation when fuel to maintain Terra’s orbit has been depleted
- Celebrating 25 Years of Terra
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 For more information, and a list of oral and poster presentations, visit the 25 Years of Terra @ AGU 2024, linked here!
