Green Light for Launch Campaign CryoSat

ESA’s ice mission CryoSat has completed its Flight Acceptance Review, confirming that all the components that make up the mission are ready for launch, which is planned for 25 February 2010 from Baikonur.

This formal review is the major part of the process of ensuring that all of the parts of the mission are in place. It is focussed on the readiness of the satellite and the preparation of the launch campaign, but also heard reports of the successful Ground Segment Acceptance Review completed in July and the status of the launcher. Although there will be future checkpoints along the road to the launch pad, this was the last major hurdle.

Generally happy with the status of the satellite, the Board requested to be informed of the progress on a few outstanding analyses which are due to be completed in mid-December. Currently in storage at IABG’s spacecraft test centre in Ottobrunn, Germany, the CryoSat-2 satellite, built to replace the original CryoSat lost in a launch failure in 2005, will ship to the Baikonur launch site in Kazakhstan on 12 January.

Once the satellite has safely arrived at the integration facilities at the launch site, it will undergo final testing before being attached to the launch vehicle. CryoSat-2 will be taken into orbit on a Dnepr launch vehicle, which is based on the SS-18 Intercontinental Ballistic Missile.

“We are looking forward to starting the launch campaign and finally getting the satellite into orbit. It’s been a long wait since we lost the first CryoSat four years ago, but now the tempo is stepping up and we’re again on the threshold of adventure,” said Richard Francis, the CryoSat Project Manager.

From an altitude of just over 700 km and reaching latitudes of 88°, CryoSat will precisely monitor changes in the thickness of sea ice variations in the thickness of the ice sheets on land. These data are urgently needed by scientists to understand exactly how Earth’s ice is changing in response to climate change. For over 15 years, the ERS satellites and Envisat have been mapping the extent of ice cover – however, in order to understand how climate change is affecting the sensitive polar regions, there is an urgent need to determine exactly how the thickness of the ice is changing to get the full picture.

Following on from GOCE, which launched in March this year and now delivering detailed data on Earth’s gravity field, and SMOS, which launched less than three weeks ago and will take measurements of soil moisture and ocean salinity for a better understanding of Earth’s water cycle, CryoSat will be the next of ESA’s Earth Explorer satellites in orbit.

Launching three missions dedicated to improving our understanding of the Earth system within 12 months will mark a significant step in ESA’s Earth Observation Programme.
