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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
