CryoSat takes significant step towards final completion

05.08.2003


CryoSat satellite design

CryoSat, the first Earth Explorer mission within ESA’s Living Planet Programme, is now entering the final phase of assembly prior to its scheduled launch next year.

CryoSat is designed to measure changes in the Earth’s terrestrial and marine ice fields and aims to provide conclusive evidence as to whether there is a trend towards diminishing polar ice cover as a result of climate change.

The first part of the Critical Design Review (CDR), which was successfully completed on 13 June, confirmed that the flight configuration design is compliant with the key design requirements and can now be integrated and tested. This step marks the beginning of the final phase of assembly of the spacecraft.



The principal purpose of the first part of the CryoSat Space Segment CDR was to review the spacecraft functionality and interfaces amongst each of its sub-systems. A second phase of the CDR will begin at the end of October to check that the final design of the spacecraft and its instrument sub-systems are capable of meeting the stringent system requirements and that the mission meets its primary scientific goals.

Construction of the satellite platform that hosts the SIRAL instrument and other sub-systems has already begun at the prime contractor Astrium GmbH’s test and integration facility in Friedrichshafen, Germany. Prototype models of key sub-systems such as the SIRAL, Central Data Management Unit, Star-trackers and Mass Memory Unit are concurrently undergoing testing. At sub-system level various suppliers around Europe, Russia and the US are contributing to the CryoSat satellite.

In parallel to the Space Segment CDR, the Ground Segment Design Review began on 19 June at ESRIN in Frascati, Italy and has now also been successfully completed. The purpose of this review was to thoroughly assess the completeness and consistency of the current Ground Segment design, together with the suitability of testing and quality control plans.

The completion of these two major milestones paves the way for the launch of CryoSat in late 2004 from Plesetsk in Russia.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

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....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

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...

Im Focus: Visual intelligence is not the same as IQ

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...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
