     "The present example will demonstrate the use of a multi-type propagator in Tudat. For that, we will consider the problem of simulating the coupled translational-rotational dynamics of Phobos around Mars, including the definition of a realistic initial state. Let's begin by talking about the forces and torques that we'll be considering as part of our dynamical problem."
