Tiivistelmä

Here, we report the detection of phosphorus and fluorine in solid
particles collected from the inner coma of comet
67P/Churyumov-Gerasimenko measured with the COmetary Secondary Ion Mass
Analyser (COSIMA) instrument on-board the Rosetta spacecraft, only a few
kilometers away from the comet nucleus. We have detected
phosphorus-containing minerals from the presented COSIMA mass spectra,
and can rule out e.g. apatite minerals as the source of phosphorus. This
result completes the detection of life-necessary CHNOPS-elements in
solid cometary matter, indicating cometary delivery as a potential
source of these elements to the young Earth. Fluorine was also detected
with CF+ secondary ions originating from the cometary dust.
