abstract = "A maneuver called Aero-Gravity Assisted is known in the literature
to increase the energy gains given by a close approach between a
spacecraft and a planet using the atmosphere of the planet. In a
sequence of studies related to this problem, the present paper
studies close approaches between a spacecraft and the Earth, in
situations where the passage is close enough to the surface of the
Earth such that the spacecraft crosses its atmosphere. The
dynamical model considers the atmosphere of the Earth, in terms of
drag and lift, the gravitational fields of the Earth and the Sun,
assumed to be points of mass, and the spacecraft. The Earth and
the Sun are assumed to be in circular coplanar orbits around their
common center of mass. The equations of motion are the ones given
by the circular planar restricted three-body problem with the
addition of the forces generated by the atmospheric drag and lift.
The primary objective is to map the variations of energy of the
orbits of the spacecraft due to this close approach. The results
show how the atmosphere affects the trajectory of the spacecraft,
generating situations where the variation of energy changes sign
with respect to the gravity part of the maneuver or where they
have a zero net result, based in the equilibrium.",
