Prof. Duncan Wingham, Lead Investigator for the CryoSat mission, stated, "The satellite is in very good shape – exceeding in-orbit specifications, the ground segment software is fine, the system of data distribution looks good and we are excited by the quality of data being received.
These data also demonstrate the added coverage that CryoSat-2 delivers. The satellite's orbit brings it closer to the poles than earlier observation satellites, covering an additional 4.6 million sq km – an area larger than all 27 European Union member states put together.
CryoSat is Europe's first mission dedicated to monitoring Earth's ice fields. The satellite carries the first radar altimeter of its kind to overcome the difficulties of measuring icy surfaces.Its primary payload, the sophisticated SAR/Interferometric Radar Altimeter (SIRAL), can measure the thickness of sea ice down to centimetres and monitor changes in the ice sheets on land, particularly around the edges where icebergs are calved from the vast ice sheets that blanket Greenland and Antarctica.
"We have had some hiccups with the science data processor – after all, a radar like this has never flown in space before. But we’ve shaken most of these out now and the results are looking very good," said CryoSat-2 Project Manager Richard Francis.
"In particular the resolution of this system is amazing. We can see lots of detail in this track over part of Antarctica, made on the day the SIRAL instrument was first switched on."
It was also announced today that orbit data from the Doppler Orbit and Radio Positioning Integration by Satellite (DORIS) radio receiver will be released in early July.
DORIS is a tracking system carried by CryoSat-2 to detect and measure the Doppler shift on signals broadcast from a network of radio beacons around the world. These signals are used for orbit determination, down to millimetre level and essential for accurately measuring the height of the ice surface.
Since the data from DORIS have been validated and shown to be excellent, they are being released to the community before the end of commissioning.
Now half-way through commissioning, CryoSat-2 is clearly well on track to delivering the precise data on ice-thickness change that are much-needed to provide a better insight into what is happening to Earth's ice cover as a result of climate change.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
