New gravity field of comet 67P/C-G based on Rosetta's Doppler and optical data
Julien Laurent-Varin, Théo James, Jean-Charles Marty +3
We provide a new gravity field of Comet 67P-C/G up to degree 4. We detect mass heterogeneity in the comet nucleus. The loss of mass is restimated at 0.28\% of the comet's total mas…
Small bodies global gravity inversion via the level-set method
Alfonso Caldiero, Sébastien Le Maistre
We propose an approach to infer large-scale heterogeneities within a small celestial body from measurements of its gravitational potential, provided for instance by spacecraft radi…
The Hera Radio Science Experiment at Didymos
Edoardo Gramigna, Riccardo Lasagni Manghi, Marco Zannoni +7
Hera represents the European Space Agency's inaugural planetary defense space mission and plays a pivotal role in the Asteroid Impact and Deflection Assessment international collab…
Mars orientation and rotation angles
Marie Yseboodt, Rose-Marie Baland, Sébastien Le Maistre
The rotation and orientation of Mars is commonly described using two different sets of angles, namely the Euler angles wrt the Mars orbit plane and the right ascension, declination…
