Terra | The EOS Flagship
WEBDec 18, 2010 · For 20 years, Terra, the flagship Earth observing satellite, has chronicled changes on Earth. Designed and built in the 1980s and 90s, NASA and Lockheed Martin engineers set out to build a satellite that could take simultaneous measurements of Earth’s atmosphere, land, and water. Its mission – to understand how Earth is changing and to ...
Science - Terra
WEB4 days ago · Science. As the Flagship Earth Observing Satellite, Terra was the first satellite to look at Earth system science, collecting multiple types of data dedicated to various areas of Earth science. Scientists are able to document relationships between Earth’s systems and examine their connections. In addition, Terra data has many applications ...
Mission - Terra
WEB5 days ago · In December 1999, NASA launched the Terra satellite as the flagship mission of the Earth Observing System to answer these questions. Terra carries five instruments that observe Earth’s atmosphere, ocean, land, snow and ice, and energy budget. Taken together, these observations provide unique insight into …
About Terra | Terra
WEBAbout Terra. Approximately the size of a small school bus, the Terra satellite carries five instruments that take coincident measurements of the Earth system: Terra is in a circular sun-synchronous polar orbit that takes it from north to south (on the daylight side of the Earth) every 99 minutes.
Multimedia - Terra
WEB4 days ago · Multimedia. Terra continues to witness many changes on the landscape, collecting some of the most iconic images of our planet since its launch in December of 1999.

MODIS - Terra
WEB1 day ago · With its sweeping 2,330-km-wide viewing swath, MODIS sees every point on our world every 1-2 days in 36 discrete spectral bands. Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor. For instance, the sensor measures the percent of the planet’s surface that is covered by clouds almost every day.
Data - Terra

WEBPrinted Wire Assemblies Back Online. To return function to 16 printed wire assemblies, including the two most recent, Terra’s Flight Operations Team rebooted Terra’s solid state recorder, on September 22, 2021.The successful reboot of Terra’s solid state recorder returned Terra to a level that allows full science acquisitions from all five instruments (ASTER, CERES, MISR, MODIS, and MOPITT).
Terra’s New Orbit
WEB3 days ago · Terra’s New Orbit. For nearly 20 years, the Terra satellite maintained a consistent orbital speed and altitude, resulting in a near-constant morning equator crossing time of around 10:30 AM. However, since February 2020, the Terra satellite has been allowed to drift in time to an increasingly-earlier equator crossing. In October 2020, Terra ...
