CryoSat Media Day September 14
On Monday September 14 media representatives will have the opportunity to attend an in-depth CryoSat background briefing at IABG's spacecraft test center in Ottobrunn near Munich, Germany.
Project managers from ESA and industry, as well as scientists and other experts, will give presentations on the spacecraft and its scientific objectives and will be available for individual interviews. The program (see below) includes a visit to the cleanroom to see the satellite at first hand before it is packed and shipped to the Baikonur launch base in Kazakhstan.The European Space Agency's CryoSat satellite is designed to provide new measurements of the extent and the thickness of the Earth's polar ice sheets. CryoSat's innovation is that it will not only be able to map the extent of the ice cover but will also measure the thickness of the ice sheets. This will provide information on ice volume and will therefore further our understanding of the effects climate change is having, and will have, on global ice cover.
After the successful launch in 2002 of Envisat, the largest Earth observation satellite ever built, ESA started to develop the Earth Explorer missions in order to provide a moderate-cost, fast response to important scientific issues using cutting-edge technologies. As the first of these missions, the original CryoSat was launched in 2005, but the launch resulted in failure with the remains of the satellite crashing down near the North Pole shortly after lift-off. Following the successful launch of ESA's gravity mission GOCE on 17 March of this year and the upcoming launch of ESA's water mission SMOS in November, the CryoSat mission will finally get off the ground with the spacecraft rebuilt by prime contractor Astrium, becoming ESA's third Earth Explorer in orbit.
Scheduled for launch this December aboard a Dnepr launcher from Baikonur in Kazakhstan, CryoSat is set to significantly improve our knowledge of global ice mass. The mission will enhance our understanding of how the polar regions are influenced by climate change as well as our knowledge of the interaction between sea ice and the oceans. It may also trigger a number of practical applications, such as improved understanding of ocean circulation and greater insights into current and future changes in sea level.

CryoSat will also survey the surface of continental ice sheets to detect small elevation changes. CryoSat's high spatial resolution radar altimeter is capable of operating in a number of modes, optimized for measurement over different surfaces. Credits: ESA - AOES Medialab
