...Scott A. Sandford; Scott Messenger; Michael DiSanti; Lindsay Keller; Kathrin Altwegg Abstract Comets are thought to have accreted in the cold, outer portions of the protosolar nebula when our Solar System was forming, and they clearly contain a higher proportion of volatiles than materials formed...

... 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...

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...

.... 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...
