We show how to compute families of periodic solutions of conservative systems with two-
point boundary value problem continuation software. The computations include detection of …

This paper concerns heteroclinic connections and resonance transitions in the planar
circular restricted 3-body problem, with applications to the dynamics of comets and asteroids …

The invariant manifold structures of the collinear libration points for the restricted three-body
problem provide the framework for understanding transport phenomena from a geometrical …

Recently, there has been accelerated interest in missions utilizing trajectories near libration
points. The trajectory design issues involved in missions of such complexity go beyond the …

Quasihalo orbits are Lissajous trajectories librating about the well known halo orbits. The
main feature of these orbits is that they keep an exclusion zone in the same way that halo …

The invariant manifold structures of the collinear libration points for the spatial restricted
three-body problem provide the framework for understanding complex dynamical …

WITHIN the last 25 years, libration point orbits have emerged as a valuable trajectory
alternative for spacecraft mission design. Beginning with the launch of the International Sun …

A brief history of the ISEE-3/ICE mission is presented. ISEE-3/ICE was the first spacecraft to
use a “halo orbit” and lunar gravity-assist maneuvers to achieve its mission objectives. Using …

Spacecraft in orbits near the collinear libration points are proving to be excellent platforms
for scientific investigations of various phenomena. Since such libration point trajectories are …

We propose a new theory for the formation of rR 1 ring structures, ie for ring structures with
both an inner and an outer ring, the latter having the form of “8”. We propose that these rings …
