The CLASP2 space experiment achieves an unprecedented map of the Sun’s magnetic field

Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events that occasionally affect the Earth occur. The extraordinary observations of the polarization of the Sun’s ultraviolet light achieved by the CLASP2 mission have made it possible to map the magnetic field throughout the entire solar atmosphere, from the photosphere until the base of the extremely hot corona. This investigation, published today in the journal Science Advances, has been carried out by the international team responsible for this suborbital experiment, which includes several scientists of the POLMAG group of the Instituto de Astrof’sica de Canarias (IAC).

All you need to know about the 2021 Mars missions

You know how it is: you wait seven months for a spacecraft to reach Mars and then three come along all at once.

This February, a trio of (uncrewed) missions are set to reach the red planet, including NASA’s Perseverance rover and the UAE’s historic Hope probe.

Why so many at the same time? All three missions launched in July 2020, a moment when Mars was at its nearest point to Earth for 26 months. Despite this leg up, each spacecraft still has to cover around 500 million km across seven months to reach their target.

Unfortunately, there’s no guarantee all these missions will be a success: over half of the missions to Mars have failed. In fact, only the US has ever landed a spacecraft on Mars, doing it eight times since 1976.

‘Touchdown confirmed!’ Perseverance landing marks new dawn for Mars science

It’s a new day on Mars. NASA’s $2.7 billion Perseverance rover has successfully landed in Jezero crater, alighting just 35 meters away from hazardous boulders it had identified during descent. At about 3:55 p.m. EST, confirmation came back of the rover safely touching its wheels down, resulting in exuberant but socially distanced applause from double-masked engineers at the mission’s control room at the Jet Propulsion Laboratory (JPL).

‘Touchdown confirmed,’ said Swati Mohan, the JPL engineer narrating the landing attempt. ‘Perseverance is safely on the surface of Mars!’ Soon after, a camera returned the first image, showing dust, rocks, and the shadow of the rover looming over the black-and-white martian surface.
