  5. Source of Saturn’s kilometric radiation revealed

    Date de publication:

    13 Novembre 2018

    Using data from the Cassini mission, scientists are unravelling the mechanisms that drive auroral radio emissions at Saturn’s poles, which are key to understanding certain characteristics of the giant ringed planet. Laurent Lamy, an astrophysicist at the LESIA space and astrophysics instrumentation research laboratory (Paris Observatory) and lead author of an article on the subject in the journal Science, gives us the details.

  7. Cassini reveals giant dust storms on Titan

    Date de publication:

    5 Octobre 2018

    These giant dust storms seen at the equator on Titan rise as far as 10 kilometres above the surface. Mars and Earth are no longer the only worlds in the solar system where such phenomena are known to occur. We put three questions to Sébastien Rodriguez, a planetologist at the IPGP global physics institute in Paris and lead author of this discovery published in the journal Nature Geoscience on 24 September.

  8. Saturn’s north polar hexagon

    Date de publication:

    19 Septembre 2018

    Analysis of data from the Cassini probe has revealed that a vortex towering more than 300 kilometres above Saturn’s north pole mirrors the famous hexagon cloud pattern observed lower in the planet’s atmosphere since 1980. Sandrine Guerlet from the LMD dynamic meteorology laboratory in Paris, who has co-authored a paper on this discovery, explains.

  9. Intense sequence for CNES, DLR and JAXA- Hayabusa2 and MASCOT arrive at asteroid Ryugu

    Date de publication:

    27 Juin 2018

    The Japanese Hayabusa2 space probe has reached the end of its 3.2-billion-kilometre journey with its passenger, the French-German MASCOT (Mobile Asteroid Surface Scout) lander. Launched in 2014, Hayabusa2 has completed three orbits of the Sun in four years, after which it began a few weeks ago its very slow approach to its final destination. Since today, Hayabusa2 is now escorting Ryugu at a close distance of some 20 kilometres, collecting images and data from this celestial object that spins on itself in a little more than seven and a half hours. MASCOT is scheduled to land on the asteroid in early October.
