It is almost a year since the Rosetta spacecraft began orbiting comet 67P/Churyumov-Gerasimenko on 6 August 2014. The orbiter’s eleven instruments are studying the comet at different wavelengths - infrared, ultraviolet, microwave and radio – as well as gathering high-resolution images and information about its shape, density, temperature and chemical composition. <br /> <br />This video outlines the mission’s scientific highlights so far – “a geologist’s playground” - and some of the latest science from three of the orbiter’s instruments: the Osiris camera, the microwave MIRO instrument and VIRTIS (visible and infrared thermal imaging spectrometer), which is studying the comet’s nucleus. <br /> <br />It contains footage from the first Rosetta science workshop, which was recently held in Rome, as well as the Max Planck Institute for Solar System Research in Germany – where a copy of Osiris is maintained in a vacuum chamber to test commands.
