ICESat has provided a critical look at ice thickness at Earth's polar regions over the course of its seven-year life. That mission has now ended.
02.24.10 - ICESat has provided a critical look at ice thickness at Earth's polar regions over the course of its seven-year life. That mission is now coming to an end.
10.19.06 - NASA scientists have found that ice losses now far surpass ice gains in the shrinking Greenland ice sheet.
03.08.06 - NASA scientists confirm climate warming is changing how much water remains locked in Earth's largest storehouse of ice and snow.
12.05.05 - Thanks to satellites, NASA has the best maps to help researchers get around the huge land of ice and snow.
11.18.05 - ICESat fired its one billionth laser shot earthward to obtain elevations from objects on the land, sea and in the air.
12.13.04 - Investigating ice, glaciers, forests, rivers, clouds and pollutants
09.30.04 - Changes in glacier flow surprises researchers.
12.09.03 - Satellite views of Earth's polar ice sheets, clouds, mountains, and forestlands are helping scientists understand how life on Earth is affected by changing climate.
10.06.03 - The principal mission of ICESat is to measure the surface elevation of the large ice sheets covering Antarctica and Greenland.
