If you were asked what station is currently orbiting 400 km above the Earth at 28 000 km/h you may be tempted to answer the International Space Station (ISS). This is of course correct but if you were to look with a good telescope behind the ISS (or tune in with the appropriate equipment) you may soon pick up a second station: a radio station.
On Friday 3 February, at 23:20 Central European Time the ISS Crew of Valery Tokarev and William McArthur are due to start an EVA from the Pirs airlock of the Russian section of the ISS wearing Russian Orlan space suits. However, a third Orlan spacesuit will be on the spacewalk with them, one that is nearing the end of its useful life. The plan is literally to throw the extra spacesuit overboard. This may not present an obvious link to radio stations but this suit is fitted with amateur radio equipment, which will transmit messages in many different languages during its time in orbit.
The spacesuit with equipment is called SuitSat-1 (also called Radio Sputnik or Radioskaf in Russian). SuitSat is a project sponsored by ARISS (Amateur Radio on the ISS) an international working group of volunteers from national amateur radio organisations. ARISS has been used as an integral part of education activities within ESA Human Spaceflight missions with the aim of developing children’s interest in space and science in general.

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...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
