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.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
