CryoSat-2, successor to CryoSat, was launched successfully from Baikonur, Kazakhstan on April 8th, 2010. The freshly launched satellite will provide accurate data on the variations of ice thickness in the Polar Regions, whether on land or on the sea surface. CryoSat-2, the third of the Earth Explorer satellites to have been launched in the past year, is part of a larger European effort to better understand the impact of climate change on these remote, yet sensitive regions.
