    How we made history by landing on a comet?

    On 12 November 2014, after a ten-year journey through the Solar System and over 500 million kilometres from home, Rosetta’s lander Philae made space exploration history by touching down on a comet for the first time. On the occasion of the tenth anniversary of this extraordinary feat, we celebrate by taking a look back over the mission’s highlights.

    Rosetta was an ESA mission with contributions from its Member States and NASA. It studied Comet 67P/Churyumov-Gerasimenko for over two years, including delivering lander Philae to the comet’s surface. Philae was provided by a consortium led by DLR, MPS, CNES and ASI.

  • Latest from Rosetta

    Latest from Rosetta

    Three years after the Rosetta mission officially ended in 2016, scientists met at ESA’s ESTEC facility in The Netherlands to discuss the latest findings at the final Science Working Team (SWT) meeting.

    From the launch in 2004, to its arrival at comet 67P in 2014, Rosetta has been an emotional and inspiring mission. Its findings have furthered our understanding of comets and changed our perceptions of how the Solar System formed.

    The mission produced an enormous amount of data which will keep many scientists busy for years. The OSIRIS camera, for example, took 100 000 images. These are archived – with the analysis of images recently providing further insight into the comet’s activity.

    Rosetta’s legacy of cometary science and data is not just continuing to produce more work, however, it’s also inspiring the next generation of scientists. Some began working on Rosetta as students and are now taking their experience forward onto ESA’s future Comet Interceptor mission.

  • Rosetta: the story continues

    Rosetta: the story continues

    This short movie shares an impression of some of the scientific highlights from Rosetta’s mission at Comet 67P/Churyumov–Gerasimenko, as told through the voices of scientists working with Rosetta’s vast dataset, two years after the mission ended.

    Rosetta launched in 2004 and travelled for ten years to its destination before deploying the lander Philae to the comet’s surface. Following the comet along its orbit around the Sun, Rosetta studied the comet’s surface changes, its dusty, gassy environment and its interaction with the solar wind. Even though scientific operations concluded in September 2016 with Rosetta’s own descent to the comet’s surface, analysis of the mission’s data will continue for decades.

    Credits: This is an ESA Web TV production. The video contains artist impressions of the spacecraft (credit: ESA/ATG medialab) and animations/infographics by ESA. Images of the comet are from Rosetta’s OSIRIS and NAVCAM cameras, as well as Philae’s CIVA camera (credits: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA – CC BY SA 4.0; ESA/Rosetta/NavCam – CC BY-SA IGO 3.0; ESA/Rosetta/Philae/CIVA).

The plasma visualisation is based on modelling and simulation by Technische Universität Braunschweig and Deutsches Zentrum für Luft- und Raumfahrt, and visualised by Zuse-Institut Berlin. The animation of Philae’s flight across the surface is based on data from Philae’s ROMAP, RPC-MAG, OSIRIS, ROLIS, CIVA CONSERT, SESAME and MUPUS instrument teams, the Lander Control Centre at DLR and the Science Operation and Navigation Center at CNES.

    ESA Euronews: Rosetta heads for glorious crash-landing

    In just a few days’ time ESA’s Rosetta mission is going to come to a close in a most extraordinary fashion, because the spacecraft is going to slowly, and deliberately crash-land into the comet that it has been orbiting for the past two years.

    Euronews is with the team as they prepare for this dramatic finale.

    ESA Euronews: El final programado de Rosetta

    En pocos días, la misión Rosetta de la Agencia Espacial Europea (ESA) tocará a su fin. Y lo hará de la forma más extraordinaria, porque la nave espacial irá a chocar, lenta y deliberadamente, contra el cometa alrededor del cual ha estado orbitando durante los últimos dos años. Nos reunimos con el equipo mientras preparan este dramático final.

    ESA Euronews: Rosetta se prépare au choc fatal sur la comète Tchouri

    Le 30 septembre prochain, la sonde Rosetta s’écrasera lentement et délibérément sur la comète autour de laquelle elle orbite depuis deux ans. Or elle n’a pas été conçue pour cela. L’issue sera fatale. Mais avant cette dernière manoeuvre, les scientifiques ont prévu d’effectuer des relevés inédits à l’approche de “Tchouri”.

  • Rosetta status

    Rosetta status

    Rosetta has another three months of science to collect before its historic mission comes to an end. But the mission is not resting on its laurels. It has just broken a new record by flying an orbit 7 kms from the comet’s centre – just 5 kms from the surface – and there are more breathtaking manoeuvres to come.

    This film describes the orbits that Rosetta will undertake around comet 67P/Churyumov-Gerasimenko, the changes in the amount of gas coming off the comet, and examines the importance of finding phosphorus and glycine – an amino acid that is essential for life.

    It also discusses the mission’s most recent discoveries of Xenon and Krypton, together with most of their isotopes. These noble gases were detected by the ROSINA instrument during the period when Rosetta was flying extremely close to the comet. More important science is expected to be released during the next few months.

  • Philae facing eternal hibernation

    Philae facing eternal hibernation

    15 months after Philae made its historic landing on a comet, its legacy is enormous even if Rosetta’s lander is facing eternal hibernation.

    Mission teams are now looking ahead to the grand finale: making a controlled impact of the Rosetta orbiter on the comet next September.Rosetta arrived at Comet 67P/Churyumov–Gerasimenko on 6 August 2014 and Philae was delivered to the surface on 12 November. After touching down Philae bounced several times and completed 80% of its planned first science sequence before falling into hibernation. 

    A contact was made with the lander on 13 June and intermittent contacts were made up to 9 July. However the results of Philae mission are unique and complement all the science harvested by the orbiter Rosetta who is continuing its quest before being sent directly to the surface of 69P late September.

  • How Rosetta wakes up from deep space hibernation

    How Rosetta wakes up from deep space hibernation

    Visualisation of how the Rosetta spacecraft wakes up from deep space hibernation, 673 million kilometres from the Sun, on 20 January 2014.

    Prior to entering hibernation on 8 June 2011, Rosetta was oriented so that its solar arrays faced the Sun, and it began rotating once per minute for stability. The only devices left running were its computer and several heaters.

    Rosetta’s computer is programmed to carry out a sequence of events to re-establish contact with the Earth on 20 January, starting with an ‘alarm clock’ at 10:00 GMT. Immediately after, the star trackers begin to warm up. Around 6 hours later the thrusters are fired and the slow rotation stops. A slight adjustment is made to Rosetta’s orientation to ensure that the solar arrays now face the Sun. Then the star trackers switch on to determine its attitude. The spacecraft rotates towards Earth, and the transmitter is switched on. Then Rosetta’s high-gain antenna points to Earth and the signal is sent. The journey takes 45 minutes before the signal is received and mission controllers can begin to check Rosetta’s health, ready for the next phase of the mission.

    The first opportunity for receiving a signal on Earth is between 17:30 GMT and 18:30 GMT.
