| Title: Dynamical problems over the asteroid surface | |
| Abstract: With the successful deployment and surface locomotion of the rovers from Hayabusa2, the asteroid surface exploration has become one of most effective ways to implement the in-situ exploration. Summarizing the unanticipated bouncing landing of Philae in Rosetta mission, the coupled orbit-attitude-collision dynamical propagation of the rover/lander is presented in this talk. The asteroid complex terrains are taken into account by proposing the rocky polyhedral model. The concept of the hop reachable domain for surface locomotion is introduced with numerical simulations and a recent theoretical study. A primitive surface rover is also designed and analyzed as a reference for Chinese future asteroid surface explorations. | |
