TL;DR: In this paper, the authors presented an overview of the regional morphology of comet 67P/C-G and used the images that were acquired at orbits ~20-30 km from the center of the comet to distinguish different regions on the surface and introduce the basic regional nomenclature adopted by all papers in this issue that address the comet morphology and surface processes.

TL;DR: In this paper, the authors show that the evolution of the visible spectrophotometric properties of samples during sublimation is consistent with the contrasts of brightness and color seen at the surface of the nucleus.
