Earth Science Missions

Seeing Earth from Space

NASA’s Earth Science Division (ESD) missions help us to understand our planet’s interconnected systems, from a global scale down to minute processes. Using observations from satellites, instruments on the International Space Station, airplanes, balloons, ships and on land, ESD researchers collect data about the science of our planet’s atmospheric motion and composition; land cover, land use and vegetation; ocean currents, temperatures and upper-ocean life; and ice on land and sea.

The Wasatch Range of mountains, covered in a deep green that becomes gradually more sage as it blends with the beige valleys below, span horizontally across the top of the image. Below that is Salt Lake City, nestled just above the Great Salt Lake. Below that is the Great Salt Lake Desert, which includes the Bonneville Salt Flats, all of which is white to off white. To the right is Great Basin National Park amid the gray brown dusty landscape. In the lower left are the Craters of the Moon and the Snake River Plain. The landscape in this portion of the image appears more true brown than the gray-brown of the lower right.
