CryoSat takes significant step towards final completion

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: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
