Trajectory Design Using a Dynamical Systems Approach With Application to Genesis
A number of missions have recently been proposed that aim to take advantage of the growing scientific interest in the region of space near libration points in the Sun-Earth system. In support of missions that include increasingly complex trajectories and incorporate libration point orbits, more efficient techniques and new philosophies for design must be considered.

Halo Orbit Generation Using the Center Manifold
In recent years, halo orbits around the Sun-Earth Lagrange points, L1 and L2, have become extremely opular for NASA missions due to the ideal observation environment and low launch energy.

The long-term forecast of station view periods
Using dynamical systems theory, a definite integral is obtained that gives the average view period of a ground station for spacecraft in circular orbits. Minor restrictions exist on the class of circular orbits to which this method can be applied. This method avoids the propagation of the orbit, which requires a lot of resources, and simplifies the algorithm used to compute the mean station view period. The integral is used for long-term station load forecast studies. It also provides a quantitative measure of the effectiveness of a ground station as a function of its latitude.
