  2. Rosetta mission Watch the climax of the space odyssey live

    Publishing date:

    September 27, 2016

    Its multiple twists and scientific discoveries have kept us on the edge of our seats. Now, in a final flourish, ESA’s Rosetta spacecraft is set to bring its mission to a close with a controlled descent to the surface of comet Churyumov-Gerasimenko on Friday 30 September. Impact is scheduled within a window 20 minutes either side of 13:20 CET. CNES invites you to watch the finale of this space odyssey live at the Cité des sciences et de l’industrie in Paris, the Cité de l’espace in Toulouse and on its website.

  7. Rosetta mission science results A fifth of Earth’s atmosphere is likely from comets

    Publishing date:

    June 13, 2017

    Thanks to the Rosetta space mission to 67P/Churyumov–Gerasimenko, which sought to gain new insights into how our solar system formed by analysing the comet and its behaviour as it approached the Sun, scientists have now determined that a fifth of Earth’s atmosphere likely comes from comets.

    Publishing date:

    July 11, 2014

    Le Système solaire s’est formé il y a 4,56 milliards d’années à la suite de l’effondrement d’une nébuleuse interstellaire semblable à celle que nous pouvons admirer à l’œil nu ou dans un télescope dans la constellation d’Orion.

    Publishing date:

    July 27, 2016

    The Electrical Support System (ESS) through which the Rosetta orbiter has been listening out for Philae will be turned off Wednesday 27 July at 11 a.m. CEST. The remaining supply of power, now ever dwindling as comet Churyumov-Gersimenko moves further away from the Sun, will be used to complete the final phases of the mission.

    For certain, the Rosetta mission that ended last September with the orbiter impacting the nucleus of comet 67P/Churyumov-Gerasimenko after a controlled descent will mark the history of space exploration. Having achieved numerous firsts, collected a wealth of data and made major discoveries, this ambitious mission—a veritable space odyssey, given the length of its journey and the operational obstacles it had to overcome— has indisputably been a huge success.

  17. So long, Rosetta!

    Publishing date:

    September 30, 2016

    All good things must come to an end, including space missions… Rosetta, Europe’s favourite space mission that has been making headlines since 2004, bowed out today in a moment of pure poetry when the orbiter landed softly on the surface of comet Churyumov-Gerasimenko. Rosetta and Philae will now remain forever in an eternal slumber, leaving behind for the public and the international space community a legacy of unforgettable feats and a treasure trove of science data.

    Even after its mission ended, the Rosetta probe is still teaching us a lot about comet 67P/Churyumov–Gerasimenko. On 9th June, Bernard Marty from the Centre de recherches pétrographiques et géochimiques (joint institute between the CNRS and the University of Lorraine) and his colleagues from the Rosina consortium (PI: K. Altwegg) published new results in Science, showing a quantitative link between comets and our planet’s atmosphere.
