Preparations for the arrival of "Jules Verne", the first European Automated Transfer Vehicle (ATV), and those for ESA astronaut Roberto Vittori’s mission, took a step forward when the unmanned Russian cargo spacecraft Progress M-52 docked yesterday, 2 March at 21.10 Central European Time (CET) with the International Space Station (ISS).
Launched two days earlier, on 28 February at 20.09 CET from the Baikonur Cosmodrome in Kazakhstan by a Soyuz rocket as ISS mission 17P, the Progress supply vehicle carried, among other cargo, a communication system made in Europe that will be used when the ATV docks with the station in 2006. The "Proximity Communication Equipment" (PCE) will provide S-band data communication between the ISS and the ATV during the last 30 kilometres before the ATV docks. It consists of two communication assemblies which are fully redundant. The system was developed and integrated under ESA contract by EADS Astrium in Toulouse, France.
Prior to its integration into the Progress vehicle, the complete PCE was checked out from 7 to 11 February by a combined ESA, industry and Russian team at the launch site in Baikonur. The equipment will be installed by the two astronauts who are now living and working in the Russian laboratory and habitation module "Zvezda", where the ATV will dock. The complete system will then be tested on the ISS in early April.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.
Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
