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.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
