The scientific community thinks that there is a higher probability that organic molecules precursors to life could form in those planets or satellites which have an atmosphere with electric storms.
Researcher Juan Antonio Morente, from the Department of Applied Physics of the University of Granada, has informed the SINC that Titan is considered to be “a unique world in the Solar System” since 1908, when Spanish astronomer José Comas y Solá found out that it had an atmosphere, something non-existent in other satellites. “In this moon there are clouds with convective movements and therefore there can be static electric fields and stormy conditions”, he explains. “It significantly increases the chance that organic and prebiotic molecules get formed, according to the theory of Russian biochemist Alexander I. Oparín and Stanley L. Miller’s experiment”, who managed to synthesize organic compounds from inorganic ones by using electric shocks. “Therefore, Titan has been one of the main objectives of the Cassini-Huygens combined mission of the NASA and the European Space Agency (ESA)”, said the researcher.An enormous resonant cavity
The electric field was measured by the sensor of mutual impedance (MIP), one of the instruments transported by the Huygens probe. The MIP consisted of four electrodes, two transmitters and two receptors, and there was a couple of transmitter-receptor in each of the pull-down arms en of the probe. The MIP sensor was preferably used to measure the atmospheric electric conductivity, but it also acted as a dipole antenna, measuring the natural electric field in the atmosphere.
“In a stable descent, without rolling, the MIP sensor would have been able to measure the peak tangential component of the electric field”, says Morente, “but unfortunately a strong wind made the probe to roll and the electrodes measured a superposition of such tangential and radial component”.Flat spectrum
This work, which has been subsidized by the former Ministry of Education and Science, the Andalusian Council and the European Union, also explains that the atmosphere of this moon of Saturn is an electromagnetic environment with high losses, and that its resonant cavity is less idean than that of the Earth.Reference:

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
