CryoSat takes significant step towards final completion


CryoSat satellite design

the CryoSat satellite platform being constructed in the spacecraft integration facility at Astrium GmbH, Friedrichshafen, Germany.

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: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

Oceans formed before Tharsis and evolved together, shaping climate history of Mars

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
