More than 400 miles above Earth, a satellite the size of a school bus is earning its frequent flyer miles. On Oct. 6, NASA’s Terra completed 100,000 orbits around Earth. Terra, which launched Dec. 18, 1999, is projected to continue operation into the 2020s.

For the first time ever, measurements from NASA Earth-observing research satellites are being used to help combat a potential outbreak of life-threatening cholera. Humanitarian teams in Yemen are targeting areas identified by a NASA-supported project that precisely forecasts high-risk regions based on environmental conditions observed from space.

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. Many sources archived Terra imagery including the Earth Observatory and NASA’s Visible Earth.

This section contains images, videos and podcasts that visualize many events and changes on Earth’s surface and also explain some of the science to which Terra contributes.

As the Flagship Earth Observing Satellite, Terra  was the first satellite to look at Earth system science with five sensors dedicated to observing the land, water, and atmosphere.

By seeing Earth from the same vantage point, but 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.

The images, videos, and podcasts illustrate and examine Earth system science as Terra observes changes on Earth over time.
