CryoSat
CryoSat, also called CryoSat-2, European Space Agency satellite designed to study the effect of climate change on ice in Earth’s polar regions. It launched from the Baikonur Cosmodrome in Kazakhstan on April 8, 2010, on a Russian Dnepr launch vehicle. CryoSat circles Earth in a polar orbit. Its primary instrument is the SAR Interferometric Radar Altimeter (SIRAL), which is designed to measure changes of less than 1 cm (0.4 inch) per year in the height of ice. (SAR stands for Synthetic Aperture Radar, a technique that uses short radar bursts to make an image.) By measuring ice over a period of years, CryoSat can help scientists to determine the rate at which climate change is affecting the amount of land and sea ice. The satellite can also be used to study water levels in lakes and rivers. The first satellite in the CryoSat series was destroyed during a launch malfunction on October 8, 2005.
