abstract = {Molecular nitrogen (N2) is thought to have been the most abundant form ofnitrogen in the protosolar nebula. It is the main N-bearing molecule in theatmospheres of Pluto and Triton, and probably the main nitrogen reservoirfrom which the giant planets formed. Yet in comets, often considered asthe most primitive bodies in the solar system, N2 has not been detected.Here we report the direct in situ measurement of N2 in the Jupiter familycomet 67P/Churyumov-Gerasimenko made by the ROSINA mass spectrometer aboard the Rosetta spacecraft. A N2/CO ratio of(5.70textpm0.66) texttimes 10--3(SEM) corresponds to depletion by a factor of textasciitilde25.4 textpm 8.9 compared to the protosolar value. This depletion suggests that cometary grains formed at low temperature conditions below textasciitilde30K},
