The first ICESat revealed that sea ice was thinning, and ice cover was disappearing from coastal areas in Greenland and Antarctica.

A satellite called ICESat that uses a laser to measure the height of the ice found that one section of ice (maybe 10 miles across) was constantly rising and falling.
Other topics include radiation effects on stellar reference sensors, geolocation for the ICESat laser altimeter, an autonomous walking inspection and maintenance robot, and a unification of artificial potential function guidance and optimal trajectory planning.

The study compared traditional ground measurements to satellite data from NASA's Ice, Cloud and Land Elevation Satellite, or ICESat, and the Gravity Recovery and Climate Experiment, or GRACE, missions to estimate ice loss for glaciers in all regions of the planet.

In fact, Borsa and his colleagues conducted their survey to obtain accurate altitude measurements that could be used to calibrate the laser altimeter on board ICESat, an Earth-orbiting craft designed to monitor ice sheets (SN: 12/24&31/05, p.
For CALIOP, these concerns were heightened by the failure of one of the lasers on board the Ice, Cloud and Land Elevation Satellite (ICESat) that occurred at the time the CALIOP lasers were being fabricated.
Recent analysis of data from both the ICESat satellite and an ongoing airborne mission called Operation IceBridge show us how the surface elevation of the ice sheet has changed.
