Ice, Cloud, and land Elevation Satellite (ICESat)
Mission Category: Earth Observing System (EOS)
Launch Date: January 12, 2003
Launch Location: Vandenberg Air Force Base, CA
Actual Completion Date: August 14, 2010
ICESat (Ice, Cloud,and land Elevation Satellite) is the benchmark Earth Observing System mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics. From 2003 to 2009, the ICESat mission provided multi-year elevation data needed to determine ice sheet mass balance as well as cloud property information, especially for stratospheric clouds common over polar areas. It also provided topography and vegetation data around the globe, in addition to the polar-specific coverage over the Greenland and Antarctic ice sheets.
