| Zusammenfassung |
| The COmetary Secondary Ion Mass Analyser (COSIMA) is one of the 3 scientific in-situ dust instruments on the ROSETTA spacecraft orbiting comet 67P/Churyumov-Gerasimenko since August 2014. COSIMA is collecting cometary particles in the inner coma by exposing metal targets, images the targets periodically and analyses the statistics and morphology of the captured particles. Some of the identified cometary grains are further investigated by secondary ion mass spectrometry. The high resolution mass spectra contain positive or negative ions of elements, organic molecules and molecular fragments originating from the selected grain surface. We will report on the highlights and lessons learned from the dusty inner coma of comet 67P/Churyumov-Gerasimenko (or C-G). |
