Cryosat is a satellite designed to monitor Earth's polar ice sheets and sea ice, crucial for understanding climate dynamics. Initially launched in 2005, the original Cryosat failed, leading to the development of Cryosat 2, which launched successfully in 2010. Equipped with advanced radar technology, Cryosat 2 provides precise measurements of ice thickness and contours, offering valuable data on the rapid reduction of Arctic sea ice. This information aids climate scientists in understanding ice dynamics and climate change. Cryosat 2 transmits data to a ground station and is expected to operate for about 3.5 years.
