Advances in the discovery and characterization of asteroids over the past decade have
revealed an unanticipated underlying structure that points to a dramatic early history of the …

Abstract On December 3rd, 2014, the Japanese Space Agency (JAXA) launched
successfully the Hayabusa2 (HY2) spacecraft to its journey to Near Earth asteroid (162173) …

This paper presents a new method for rapid generation of time-optimal trajectories for
asteroid landing via convex optimization. To overcome the nonconvex difficulty due to the …

Our knowledge of the internal structure of asteroids is, so far, indirect–relying entirely on
inferences from remote sensing observations of the surface, and theoretical modeling of …

The nature and origin of the asteroids orbiting in near-Earth space, including those on a
potentially hazardous trajectory, is of both scientific interest and practical importance. We …

Sampling soil or rocks from extraterrestrial celestial bodies is the essential step to detecting
the existence of water and life in celestial bodies, it is also an important channel to obtain …

We study the orbits and manifolds near the equilibrium points of a rotating asteroid. The
linearised equations of motion relative to the equilibrium points in the gravitational field of a …

The fuel-optimal control problem of soft landing becomes a significant challenge due to the
highly irregular gravitational field of an asteroid. An indirect method is used to deal with this …

This paper proposes a new nonlinear guidance algorithm applicable for asteroid both
hovering and landing. With the new guidance, a spacecraft achieves its target position and …

Little is known about carbonaceous asteroids weathering in space as previous studies have
struggled to define a general spectral trend among dark surfaces. Here we present …
