The dust of comet 67P/Churyumov-Gerasimenko

After a 10-year journey, the European spacecraft Rosetta arrived at comet 67P/Churyumov-Gerasimenko (67P) on August 6, 2014. In order to conduct intensive research for 26 months, a total of 21 instruments were on board the Rosetta orbiter and the Philae lander. The mass spectrometer named COSIMA (Cometary Secondary Ion Mass Analyzer) was one of the orbiter instrument and was designed to collect cometary dust particles ejected from 67P nucleus, imaged them and analyzed in situ their composition. I will present the Rosetta space mission, as well as results from the COSIMA instrument regarding the organic content of the cometary dust particles.
