Spacecraft observations revealed that rocks on carbonaceous asteroids, which constitute
the most numerous class by composition, can develop millimeter-to-meter-scale fractures …

The dynamical environment in the close-proximity of small celestial bodies is characterized
by a very weak and irregular gravity field. In this low-acceleration deep-space environment …

This paper presents a finite element method to search for equilibrium points around a
heterogeneous small body, which degenerates from the full two-body problem in finite …

Abstract The Double Asteroid Redirection Test (DART) mission demonstrated the feasibility
of altering an asteroid's orbit through kinetic impact. However, uncertainties associated with …

The development of dedicated numerical codes has recently pushed forward the study of N-
body gravitational dynamics, leading to a better and wider understanding of processes …

Some asteroids flying close to Earth may pose a threat of impact. Among them, the structural
and dynamical characteristics of rubble-pile asteroids can be changed because of the tidal …

This paper investigates the motion of a lander in a fully coupled spin–orbit binary system.
The full dynamical equations are established, including the states of the lander and the two …

The dynamics of binary asteroid systems are referred to as the full two-body problem (F2BP),
which is one of the principal problems in astrodynamics. The gravitational interactions …

The tradeoff between accuracy and efficiency in gravitational field modeling for binary
asteroid landing is one of the challenges in dynamical analyses. Four representative …

Numerical calculation provides essential tools for deep space exploration, which are
indispensable to mission design and planetary research. In a specific case of binary asteroid …
