Abstract

Abstract: For the landing site selection and operations of Philae, operational CSTMs (comet surface thermal models) had to be calculated in a frenzy: Between August 2014 (orbit insertion) to September (final selection). Input relied on two Rosetta Orbiter instruments, VIRTIS (IR) and MIRO (microwave, subsurface) to estimate thermal inertia. Comet 67P/Churyumov-Gerasimenko was then, r> 3AU, rather inactive; so sublimation was not considered for the predictive models. We explain the model parameters, give some examples and report on the numerous unexpected difficulities to get a CSTM right on a small body with a complex shape.
