... Rosetta mission to comet 67P/ChuryumovGerasimenko ( Meech 2017 ). Molecular species that sublimate directly from a comet's nucleus are called “parent molecules” and their photo-dissociation products are called “daughter species”. Most of the species observed at optical wavelengths do not represent...

.... Prior to the investigation of comet 67P/ChuryumovGerasimenko by the European Space Agency's Rosetta mission (Grady et al. 2018 this issue), there had been close encounters with six other comets ( Fig. 1 ). Rosetta included both a rendezvous spacecraft for extended measurements near the comet...

Matter must have assembled with low relative speed to create the contact-binary and onion-shell morphology of comet 67P/ChuryumovGerasimenko, observed in close proximity by the Rosetta mission (see Grady et al. 2018 this issue). Once they had formed, some comets were scattered during close...

..., the Rosetta spacecraft orbited, and deposited a probe on comet 67P/ChuryumovGerasimenko, as described by Grady et al. (2018 this issue). In many ways, we live at the perfect time to be “cometologists”. However, the mission that most cometologists most desire to see would be a truly cryogenic (<−180 °C...

..., the determination of the water/dust ratio is more complex and requires accurate modeling of the light scattered by the dust particles. Detailed observations in the 3-µm region of the nucleus of comet 67P Churyumov Gerasimenko revealed the general absence of water ice on its surface, and that hydrogen is instead...

That is, the upper limit on Titan’s atmospheric 84 Kr/CH 4 ratio (<10 −6 ) from the Huygens probe is much lower than the value (~8 × 10 −5 ) determined at comet 67P/ChuryumovGerasimenko by the European Space...
