  1. Grand Finale- Cassini bids farewell

    Publishing date:

    September 14, 2017

    15 September 2017 will mark the end of the Cassini mission, after 13 years exploring the Saturn system. With its fuel fast running out, the spacecraft will plunge into the gas giant’s atmosphere where it will acquire one last series of science data before breaking up and falling silent forever. Philippe Zarka, astrophysics research director at the LESIA space and astrophysics instrumentation research laboratory at the Paris Observatory, takes us through Cassini’s final minutes.

  2. Source of Saturn’s kilometric radiation revealed

    Publishing date:

    November 13, 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.

  3. Cassini: Destination Moons

    Publishing date:

    September 6, 2017

    In the space of 13 years, Cassini observed Saturn and devoted a lot of attention to its moons. With the mission now about to end, Patrick Michel, astrophysicist, planetologist and research director at the Côte d’Azur Observatory in Nice, reflects on the discoveries it has made about the planet’s natural satellites.

  4. Huygens- Landing on Titan

    Publishing date:

    September 11, 2017

    In December 2004, the U.S. Cassini spacecraft released the European Huygens module for the most-distant landing yet accomplished in the history of space exploration. Titan, Saturn’s largest moon, was the target and the high point of this collaboration that has brought great discoveries in planetology. With the Cassini mission now set to end, Athéna Coustenis, research director at the LESIA space and astrophysics instrumentation research laboratory at the Paris Observatory, looks at what it found there.

  6. Saturn’s rings through the eyes of Cassini

    Publishing date:

    September 4, 2017

    As well as studying Saturn and its moons, Cassini also trained its sights on the planet’s rings, analysing their composition, structure and dynamics to learn more about the physics of these very special features. Sébastien Charnoz, an astrophysicist at Paris Diderot University and research scientist at the IPGP global physics institute in Paris, looks back at what the mission has found.
