,A Note on Dynamics About the Coherent Sun–Earth–Moon Collinear Libration Points,tudy both situations in the framework of a single, coherent model, the Hill restricted four-body problem. This model is presented in a Sun–Earth rotating reference frame to complement its earlier Earth–Moon frame formulation. We provide an overview of the planar quasi-periodic orbits that originate

The Trojan Problem from a Hamiltonian Perturbative Perspective,Starting from a representation of the Elliptic Restricted 3-Body Problem in terms of modified Delaunay variables, we propose a sequence of canonical transformations leading to a Hamiltonian decomposition in the three degrees of freedom (fast, synodic and secular). From such a decomposition, we intro

Formation Flying Guidance for Space Debris Observation, Manipulation and Capture,n-depth discussion of robotic arm based capture of debris. Guidance aspects of active debris removal missions are discussed. Mission phases for active debris removal missions are rendezvous, inspection, attitude synchronization and capture and de-tumbling. The need for attitude synchronization is dr

Low Thrust Relative Motion Control of Satellite Formations in Deep Space,onsidered. A family of artificial Halo orbits with the same periods, around the .. and .. Lagrange points in the Earth-Sun system is found using the pseudo-arc-length continuation method. The orbits are used are reference trajectories for satellites to track. The problem of orbit stability, bounding

Efficient Modelling of Small Bodies Gravitational Potential for Autonomous Proximity Operations, Recent developments in on-board navigation paved the way for autonomous proximity operations. The missing elements for achieving this goal are a gravity model, simple enough to be easily used by the spacecraft to steer itself around the asteroid, and guidance laws that rely on a such an inherently

Sun-Earth L1 and L2 to Moon Transfers Exploiting Natural Dynamics,der to assess the feasibility of future disposal or lifetime extension operations. With an eye to the probably small quantity of propellant left when its operational life has ended, the spacecraft leaves the libration point orbit on an unstable invariant manifold to bring itself closer to the Earth

Formulating Poorly Water Soluble Drugspolynomials) is addressed, and a method for analytically estimating the minimum time of a manoeuvre is proposed. The method requires low computational capacity, and a comparison with optimal control solutions shows its relative performance.
