Valley fever is a dangerous threat to human health – and cases are on the rise in the arid southwestern United States, as wind from increasing dust storms can transport the fungal spores that cause the disease. Valley fever is caused by the Coccidioides fungus, which grows in dirt and fields and can cause fever, rash and coughing. Using NASA resear

Fertilizers used in farming contain high amounts of nutrients, such as phosphorous, to help crops grow. But these same nutrients can cause unwanted plant growth and potentially harm ecosystems miles away if agricultural runoff flows into nearby rivers, lakes, or coastal waters.

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.
