Abstract. 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 rotating asteroid, the characteristic equation and the stable conditions of the equilibrium points are derived and discussed. First, a new metric is presented to link the orbit and the geodesic of the smooth manifold. Then, using the eigenvalues of the characteristic equation, the equilibrium points are classified into 8 cases. A theorem is presented and proved to describe the structure of the submanifold as well as the stable and unstable behaviours of a massless particle near the equilibrium points. The linearly stable, the non-resonant unstable, and the resonant equilibrium points are discussed. There are three families of periodic orbits and four families of quasi-periodic orbits near the linearly stable equilibrium point. For the non-resonant unstable equilibrium points, there are four cases; for the periodic orbit and the quasi-periodic orbit, the structures of the submanifold and the subspace near the equilibrium points are studied for each case. For the resonant equilibrium points, the dimension of the resonant manifold is greater than four, and we find at least 1 family of periodic orbits near the resonant equilibrium points. Besides, this theory is 2 applied to asteroids 216 Kleopatra,

The landing process to an asteroid is discussed with a Nimble Lander. The miniature harpoons are chosen as the anchoring device to landing to asteroid in the Nimble Lander. The analysis results provide detailed information of the anchoring with harpoon as anchoring device. Many different designs of harpoon have been tested by simulation, the best of three designs of harpoon are analyzed for anchoring to Apophis. Instead of the modelling of the anchor as a rigid cylindrical projectile in penetration models, the deformation of the harpoon is fully considered in the anchoring analysis. The analysis provides ground base a reliable design anchoring system for landing to Asteroids.

“…In 2003, the Japanese Space Agency's (JAXA) Hayabusa mission was the first to focus on an asteroid with an aim to return a sample (Fujiwara et al, 2004). With only a basic scientific payload onboard Hayabusa, data gathered on the S-type asteroid Itokawa have nevertheless yielded incredible results (Nagao et al 2011, Tsuchiyama et al 2011) Ideas for visiting a Vtype NEO in a sample return mission are presented in the work of Duffard et al (2011).…”
