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.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
