abstract = "Lagrangian points L4 and L5 lie at 60 ahead of and behind the Moon
in its orbit with respect to the Earth. Each one of them is a
third point of an equilateral triangle with the base of the line
defined by those two bodies. These Lagrangian points are stable
for the Earth-Moon mass ratio. As so, these Lagrangian points
represent remarkable positions to host astronomical observatories
or space stations. However, this same distance characteristic may
be a challenge for periodic servicing mission. This paper studies
elliptic trajectories from an Earth circular parking orbit to
reach the Moon's sphere of influence and apply a swing-by maneuver
in order to re-direct the path of a spacecraft to a vicinity of
the Lagrangian points L4 and L5. Once the geocentric transfer
orbit and the initial impulsive thrust have been determined, the
goal is to establish the angle at which the geocentric trajectory
crosses the lunar sphere of influence in such a way that when the
spacecraft leaves the Moon's gravitational field, its trajectory
and velocity with respect to the Earth change in order to the
spacecraft arrives at L4 and L5. In this work, the planar Circular
Restricted Three Body Problem approximation is used and in order
to avoid solving a two boundary problem, the patched-conic
approximation is considered.",
