ICESat's Notable Moments in Science
NASA GSFC - 2010 Feb 24
Over the last decade, NASA has launched a series of satellites to monitor the health of our planet. One such satellite -- the Ice, Cloud and land Elevation Satellite (ICESat) -- has provided a sustained, big-picture look at ice thickness at Earth's polar regions.

Now, after seven years in orbit and 15 laser-operation campaigns, ICESat has stopped collecting science data. The last of three lasers on the satellite's Geoscience Laser Altimeter System (GLAS) ceased emitting light on Oct. 11, 2009. Attempts to restart the lasers have ended, and NASA is pursuing options for satellite decommissioning.
