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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
