The figure above shows a computational grid from Ying Liao at the University of Bern made from an accurate shape model of comet 67P. This grid (with over 140,000 facets for the cometary surface) will be used together with observed surface temperatures to test different models of outgassing. The grid resolution used for such modelling is a compromise between accuracy and computational time – each model run will take about 14 hours. The colours in the grid are to guide the eye and don’t have any scientific meaning.
