Asymptotic expansion of closed orbits in homology classes for Anosov flows. [PDF]
In this paper we give an asymptotic expansion including error terms for the number of closed orbits in the homology classes for homological full Anosov flows. In particular we obtain formulae concerning the coefficients of error terms which depend on the

Asymptotic analysis of displaced lunar orbits [PDF]
The design of spacecraft trajectories is a crucial task in space mission design. Solar sail technology appears as a promising form of advanced spacecraft propulsion which can enable exciting new space science mission concepts such as solar system ...

Survey of highly non-Keplerian orbits with low-thrust propulsion [PDF]
Celestial mechanics has traditionally been concerned with orbital motion under the action of a conservative gravitational potential. In particular, the inverse square gravitational force due to the potential of a uniform, spherical mass leads to a family

Cylindrically and spherically constrained families of non-Keplerian orbits [PDF]
This paper introduces new families of Sun-centered non-Keplerian orbits (NKOs) that are constrained to a three-dimensional surface such as a cylinder or sphere. As such, they are an extension to the well-known families of two dimensional NKOs.

Natural and sail-displaced doubly-symmetric Lagrange point orbits for polar coverage [PDF]
This paper proposes the use of doubly-symmetric, eight-shaped orbits in the circular restricted three-body problem for continuous coverage of the high-latitude regions of the Earth. These orbits, for a range of amplitudes, spend a large fraction of their

On the stability of displaced two-body lunar orbits [PDF]
In a prior study, a methodology was developed for computing approximate large displaced orbits in the Earth-Moon circular restricted three-body problem (CRTBP)by the Moon-Sail two-body problem.

New families of non-Keplerian orbits : Solar sail motion over cylinders and spheres [PDF]
This paper presents new families of Sun-centered non-Keplerian orbits (NKOs), where the motion of a high-performance solar sail is confined to either a cylindrical or spherical surface.

Extension of Martian orbits using continuous low-thrust propulsion [PDF]
There has recently been significant interest in exploration of the Martian surface and atmosphere with a view to future human exploration. Thus missions must be developed which are responsive to these scientific goals.
