From an engineering perspective, in turn, there are challenges to be faced in order to increase the scientific return of this kind of missions. One key aspect is the modelling of the gravitational field, because it enables safe close proximity operations. Usually, the lack of accurate knowledge of the shape of the minor body prevents one from producing a high-fidelity model of the gravity field before the launch of the mission. Therefore, models are elaborated from data collected in-situ. Nonetheless, close proximity operations require a high level of autonomy on-board, favouring lightweight and accurate gravity models to be used during final phases. In this talk, a comparison of state-of-the-art gravitational modelling techniques will be provided, as well as a new optimisation procedure for a mascons description. In addition, three relevant engineering applications for close proximity operation around minor bodies are presented: 1) trajectory optimisation; 2) navigation using Convolutional Neural Networks and 3) robust control for a powered landing.
