CryoSat Mission lost due to launch failureOctober 11, 2005ESA PR 44-2005. Today at 21.00 CEST Mr Yuri Bakhvalov, First Deputy Director General of the Khrunichev Space Centre on behalf of the Russian State Commission officially confirmed that the launch of CryoSat ended in a failure due to an anomaly in the launch sequence and expressed his regret to ESA and all partners involved. Preliminary analysis of the telemetry data indicates that the first stage performed nominally. The second stage performed nominally until main engine cut-off was to occur. Due to a missing command from the onboard flight control system the main engine continued to operate until depletion of the remaining fuel. As a consequence, the separation of the second stage from upper stage did not occur. Thus, the combined stack of the two stages and the CryoSat satellite fell into the nominal drop zone north of Greenland close to the North Pole into high seas with no consequences to populated areas. An investigating commission by the Russian State authorities has been established to further analyze the reasons for the failure, results are expected within the next weeks. This commission will work in close cooperation with a failure investigation board consisting of Eurockot, ESA and Khrunichev representatives. This information is released at the same time by Eurockot and ESA. European Space Agency |

Arctic sea ice annual freeze-up underway After reaching the second-lowest extent ever recorded last month, sea ice in the Arctic has begun to refreeze in the face of autumn temperatures, closing both the Northern Sea Route and the direct route through the Northwest Passage. Arctic ice on the verge of another all-time low Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. GOCE Earth Explorer satellite to look at the Earth's surface and core The European Space Agency is about to launch the most sophisticated mission ever to investigate the Earth's gravitational field and to map the reference shape of our planet - the geoid - with unprecedented resolution and accuracy. Scientists endure Arctic for last campaign prior to CryoSat-2 launch An international group of scientists has swapped their comfortable offices for one of the most inhospitable environments on the planet to carry out a challenging field campaign that is seen as the key to ensuring the data delivered by ESA's ice mission CryoSat will be as accurate as possible. Less Arctic ice means higher risks, experts warn The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday. Satellites witness lowest Arctic ice coverage in history The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage - a long-sought short cut between Europe and Asia that has been historically impassable. ESA satellite guides polar explorers across disintegrating sea ice Two Belgian explorers currently nearing the end of a staggering 2 000 km trek across the Arctic Ocean were recently guided through hazardous conditions using observations from Envisat, as sea ice in the Lincoln Sea began to break up unexpectedly. Satellites shed light on global warming As climate change continues to make headlines across the world, participants at the 2007 Envisat Symposium this week are hearing how Earth observation satellites allow scientists to better understand the parameters involved in global warming and how this is impacting the planet. Polar explorers use satellite broadband to stay in touch A team of young explorers from the Climate Change College are on a ten day field trip, participating in ESA's CryoSat validation experiment on the Greenland Ice Sheet.
