abstract = "In recent years, several missions have been proposed for asteroids
and comets, such as: Aster, Dawn, MarcoPolo-R, NEAR Shoemaker and
Rosetta. Considering that such bodies, due to its high
eccentricity, may have the periapsis near the Sun and the apoapsis
farthest, the influence of radiation pressure on the spacecrafts
may become relevant. Also, with the wide range of asteroid-Sun
distances covered during an orbital period, the dynamics becomes
more complex. The idea here is to study orbital transfers, in the
restricted three-body problem, considering the effects of the
radiation pressure in the trajectory of a spacecraft in a
bi-impulsive maneuver in an asteroid system. Transfers among the
Lagrangian points and between the Lagrangian points and the
asteroids are considered. The results show that the radiation
pressure has a significant participation in the process, because
the gravitational force in an asteroid system is smaller when
compared with systems having larger bodies. In the case of an
asteroid system, it is possible to find solutions with lower and
higher fuel consumption by considering the initial position of the
spacecraft when the maneuver begins. The figure 1 shows a previous
result of this work for maneuvers around the double asteroid
1996FG3. The effects of the solar radiation pressure in the
trajectory of the spacecraft can be modulated by changing the
area/mass of the spacecraft, so it is possible to increase those
effects by adding large panels to the spacecraft, if it is
interesting for the mission. The idea is not to use the radiation
pressure as a control, but just to measure its effects when
performing the bi-impulsive transfer.",
