This special session will be devoted to presenting the first (and latest) results of the Rosetta mission obtained at the comet 67P/Churuymov-Gerasimenko. Rosetta is slowly approaching its target. On 23 May it passed below 1.000.000 km from the comet. Early observations in April/early May by its OSIRIS camera showed that the comet activity has started according to prediction models (http://blogs.esa.int/rosetta/2014/05/15/comet-67pc-g-is-becoming-active/). Rosetta will rendezvous with 67P on 7 August, when it will come within 100 km. The programme will consist of invited talks only. Additional Rosetta observation results may be presented in other sessions, especially in SB6.
