.... Detailed study of actual cometary bodies, what they are made of and how they evolve, requires close-up investigation by spacecraft. 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...
