The intense mechanical testing period is finally over for the CryoSat satellite, and with launch just a couple of months away - the very last checks are being made before the spacecraft is packed up and shipped to the launch site in Plesetsk, Russia.
During the last 12 months the satellite has been undergoing stringent mechanical and environmental tests at the Space Test Centre at IABG (Industrieanlagen-Betriebsgesellschaft mbH) in Ottobrunn, Germany. Unfortunately, some concerns were raised about how a few of the components were functioning and consequently, repair and replacement activities hampered the testing programme and slightly delayed the launch date. Now, however, there just remains the final software checks before the satellite and its support equipment are packaged for the long voyage to Russia for launch at the end of September.
The last phase of the testing programme focused on rigorous acoustic tests, which subjected the satellite to the same levels of noise that it will be exposed to during launch. CryoSat will be launched on a Rockot launch vehicle from the remote Plesetsk Cosmodrome about 800 km north of Moscow in Russia. Rockot is one of the modified Russian Intercontinental Ballistic Missile (ICBM) SS-19 launchers, which were decommissioned as a result of the Strategic Arms Reduction Treaty in 1991. The adaptation of the SS-19 uses the original two lower liquid propellant stages of the ICBM in conjunction with a new Breeze-KM third stage for commercial payloads.

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...
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...
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...
