DOI: 10.1016/j.paerosci.2019.05.009
Abstract: Currently, the explorations of small solar system bodies (asteroids and comets) have become more and more popular. Due to the limited measurement capability and irregular shape and diverse spin status of the small body, uncertainties… read more here.

DOI: 10.1109/access.2021.3084456
Abstract: Compared with planets and their moons, small bodies retain the characteristics of their early formation. Therefore small bodies, especially Near Earth Asteroids (NEA), have become one of the most valuable targets in space exploration. This… read more here.

DOI: 10.1109/taes.2021.3088495
Abstract: In lack of information with regard to the diverse topology on the small-body surface, operation safety of the spacecraft can be hardly guaranteed in advance. To improve onboard environment adaptability in future missions, an agile… read more here.
