Blinding dust storms can seriously ruin your plans for a landing on Mars. ESA is adapting the global climate models that we use to forecast our weather on Earth for the turbulent conditions that Mars offers its future visitors.
You could hardly call the weather on Mars pleasant, and presently it is far from predictable. As well as having an average surface temperature of -63°C, and a thin, inhospitable atmosphere of mainly carbon dioxide, last year, a springtime dust storm smothered the entire planet for months. There are also dust devils, which are swirling columns of dust that can reach several kilometres in height that frequently race across the barren surface. Such severe and dusty weather conditions can interfere with the manoeuvres made by spacecraft as they enter an orbit around the planet. For a craft landing on the surface, scientific investigations would have to be put on hold until the weather got better.
Like all travellers, ESA scientists want to make sure that the weather is good when future missions arrive on Mars. They have developed a global atmospheric circulation model for Mars, which uses the same principles as those developed for Earth`s erratic weather patterns.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
