On Thursday 15 March, at the headquarters of the European Space Agency, a co-operation agreement was signed between ESA and the Centre National dÉtudes Spatiales for the development of Alphabus, Europes next generation of telecommunication satellites.
The signature of this co-operation agreement follows the signature of a contract in June 2005 between the European Space Agency (ESA), the Centre National d’Études Spatiales (CNES), EADS Astrium and Alcatel Space (which has since become Alcatel Alenia Space) who jointly committed to the Alphabus development programme and to the production of the first flight model around 2009.
The Alphabus programme is supported jointly by ESA and CNES. The agreement which has just been signed establishes the arrangements for cooperation between ESA and CNES in relation to the development and the qualification of a generic line of large platforms for geostationary telecommunication satellites, the provision of a flight model from this generic line and its validation in orbit.

First diode for magnetic fields
21.11.2018 | Universität Innsbruck
Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
