During the last weeks of July, the ROSETTA spacecraft made its final approach to comet 67P/Churyumov-Gerasimenko, revealing a two lobed object that would be a challenge to model. The first real rotation "movies", taken between August 1 and 4 and another set from August 8 allowed a group working at the Laboratoire d'Astrophysique de Marseille (LAM), to construct a first crude full-resolution shape model, building on earlier work on approach images also performed at LAM. During the next weeks and months, higher and higher resolution images became available at a variety of illuminations and viewing geometries, allowing the refinement of the shape and the construction of surface topography to sub-meter scale. We present a potpourri of preliminary results from this most intriguing object.
