Latest CryoSat Stories
ESA is about to launch the most sophisticated of Earth Observation satellites to investigate the Earth's gravitational field with unprecedented resolution and accuracy.
With three Earth Explorer satellites set to launch this year, another three under construction and up to three more about to be selected for feasibility study, 2009 promises to be a significant year for ESA's contribution to Earth science â€“ paving the way to a clearer understanding of how our planet works.
The idea of a white Christmas may seem magical for many of us, but spare a thought for a team of scientists forgoing the festive season to take part in a novel campaign being carried out in one of the most inhospitable regions on Earth to support ESA's ice mission CryoSat.
The European Space Agency says it has paired its European Remote Sensing-2 satellite with its Envisat satellite in their second tandem operation. ERS-2, the space agency's veteran spacecraft, and Envisat, the largest environmental satellite ever built, both carry Synthetic Aperture Radar instruments that provide high resolution images of the Earth's surface. By combining two or more SAR images of the same site, slight alterations that may have occurred between acquisitions can be detected,...
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.
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.
The European Space Agency is about to launch the most sophisticated mission ever to investigate the Earthâ€™s gravitational field and to map the reference shape of our planet â€“ the geoid - with unprecedented resolution and accuracy.
Following a formidable 106-day trek across the Arctic, which ended with the two Arctic Arc expedition members relying on Envisat images to guide them safely through disintegrating sea-ice, intrepid polar explorer Alain Hubert recently visited ESA to handover a unique set of snow-depth measurements.
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.
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.
