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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
