COSIMA - Cometary Dust Analysis in the inner coma of Comet 67P/Churyumov-Gerasimenko
Abstract
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 near the nucleus and inner coma. High resolution mass spectra will contain ions of complex mixtures of mineral compounds and organic molecules as well as molecular fragments representing the elements and molecules on the surface of the cometary grains. We will report on our envisaged in-situ analysis goals of cometary grains as captured, imaged and analysed by COSIMA.
