Cosima - Cometary Dust Analysis Next to Comet 67P/Churyumov-Gerasimenko
Wednesday, 17 December 2014: 11:10 AM
After a long journey through the inner solar system, ESA’s corner stone mission ROSETTA has arrived at comet 67P/Churyumov-Gerasimenko. COSIMA or the COmetary Secondary Ion Mass Analyzer onboard ROSETTA is a secondary ion mass spectrometer focussing on in-situ measurements of the composition of cometary grains collected next to the nucleus and inner coma. High resolution mass spectra will contain complex mixtures of mineral and organic elements and molecules as well as molecular fragments representing the elements and molecules on the surface of the cometary grains. We will report on first results of the in-situ analysis of cometary grains as captured, imaged and analysed by COSIMA .
