The maiden flight of a Soyuz 2-1a launch vehicle took place on Monday 8 November 2004 from the Plesetsk Cosmodrome in Russia at 21:30 Moscow time (19:30 Paris). Starsem, Arianespace and their Russian partners report that the mission was accomplished successfully.
This launch marks a major step forward in the Soyuz evolution programme as this modernised version of the launcher implements a digital control system providing additional mission flexibility and enabling control of the launch vehicle with a larger fairing. The next step will be the introduction of the Soyuz 2-1b. This launcher version will have a more powerful third-stage engine to significantly increase the overall launch vehicle performance and provide additional payload mass capability. The inaugural flight of the Soyuz 2-1b is presently scheduled for mid-2006 from Baikonur.
Both new versions of the Soyuz launcher will be adapted in view of their exploitation by Arianespace from the Europe’s spaceport in French Guiana. This will be made possible through the “Soyuz at CSG” ESA programme, which encompasses the development of a Soyuz launch complex on the territory of Sinnamary and participation in the Soyuz 2-1b development. The Soyuz at CSG programme is a key building block in the implementation of strategic cooperation between ESA and the Russian Space Agency, which falls under the general framework of the Agreement between the Government of the Russian Federation and ESA on Cooperation and Partnership in the Exploration and Use of Outer Space for Peaceful Purposes, signed in Paris on 11 February 2003.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
