Rotational dynamics of subsolar sublimating triaxial comets

Mysen, Eirik

A model with subsolar water sublimation on a triaxial, ellipsoidal comet nucleus is presented for the calculation of reactive torques. The resulting differential equations describing the comet's rotation are then Hamiltonian, and gravity-gradients are trivial to include. While effects derived from a weak perturbing function are neither able to cha…

Scientific instruments studied by Galileo Avionica for Mars surface exploration

Cosi, M.; Battistelli, E.; Bini, A. +3 more

Several missions for planetary explorations, including comets and asteroids, are planned by the space agencies: Rosetta (close to the launch date at the time of writing) Bepi Colombo, Mars Programme in all its past and next missions. The satisfaction of this scientific request calls for the development of some instruments and facilities devoted to…
