Launch of CryoSat-2 ice satellite successful

Washington, April 9 (ANI): CryoSat-2 ice satellite, Europe's first mission aimed at studying the Earth's ice, has been successfully launched from Kazakhstan.

From its polar orbit, CryoSat-2 will send back data leading to new insights into how ice is responding to climate change and the role it plays in our 'Earth system'.he CryoSat-2 satellite was launched on April 8 at 15:57 CEST (13:57 UTC) on a Dnepr rocket provided by the International Space Company Kosmotras from the Baikonur Cosmodrome in Kazakhstan.

The signal confirming that it had separated from the launcher came 17 minutes later from the Malindi ground station in Kenya.

CryoSat-2 replaces the original CryoSat satellite that was lost in 2005 owing to a launch failure.

The mission objectives, however, remain the same: to measure changes in the thickness of the vast ice sheets that overlie Antarctica and Greenland, as well as variations in the thickness of the relatively thin ice floating in the polar oceans.

Volker Liebig, ESA's Director of Earth Observation Programmes, said: "We know from our adar satellites that sea ice extent is diminishing, but there is still an urgent need to understand how the volume of ice is changing.

"To make these calculations, scientists also need information on ice thickness, which is exactly what our new CryoSat satellite will provide. We are now very much looking forward to receiving the first data from the mission."

The launch of CryoSat-2 marks a significant achievement for ESA's Earth observation programme and brings to three the number of its Earth Explorer satellites placed in orbit, all having been launched within a little over 12 months.

CryoSat-2 follows on from the Gravity field and steady-state Ocean Circulation Explorer (GOCE) mission, launched in March 2009, and the Soil Moisture and Ocean Salinity (SMOS) mission, launched last November.arth Explorers are launched in direct response to issues identified by the scientific community and aim to improve our understanding of how the Earth system works and the effect that human activity is having on natural processes.

In response to this need, CryoSat-2 is carrying the first radar altimeter of its kind to overcome the difficulties of measuring icy surfaces.

Now that CryoSat-2 is safely in orbit, the Mission Control Team at ESA's European Space Operations Centre in Darmstadt, Germany is busy with the critical 'Launch and Early Operations Phase'. (ANI)
