Using low Lift-to-Drag spacecraft to perform upper atmospheric Aero-Gravity Assisted maneuvers
(Elsevier, 2022-05-21)
The Gravity Assisted Maneuver has been applied in lots of space missions, to change the spacecraft heliocentric velocity vector and the geometry of the orbit, after the close approach to a celestial body, saving propellant ...
Strategies for plane change of Earth orbits using lunar gravity and derived trajectories of family G
(Springer, 2009-04-01)
The dynamics of the circular restricted three-body Earth-Moon-particle problem predicts the existence of the retrograde periodic orbits around the Lagrangian equilibrium point L1. Such orbits belong to the so-called family ...
STUDYING DIRECT AND INDIRECT EFFECTS OF IMPULSES IN POWERED AERO-GRAVITY-ASSIST MANEUVERS AROUND VENUS
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2018-10-01)
The study of aero-gravity-assisted maneuvers around Venus is the focus of the present paper. These are maneuvers that combine the passage by the gravity field of the planet with an impulsive maneuver that is applied at the ...
Studying direct and indirect effects of impulses in powered aero-gravity-assist maneuvers around venus
(2018-10-01)
The study of aero-gravity-assisted maneuvers around Venus is the focus of the present paper. These are maneuvers that combine the passage by the gravity field of the planet with an impulsive maneuver that is applied at the ...
Atmospheric close approaches with the Earth considering drag and lift forces
(2016-10-01)
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 ...

Applying the perturbative integral in aeromaneuvers around Mars to calculate the cost
(Springer Nature, 2022-03-23)
The perturbative integral method was applied to quantify the contribution of external forces during a specific interval of time in trajectories of spacecraft around asteroids and under the Luni-solar influence. However, ...
Natural Quasi-Rendezvous and Evasive Maneuvers assisted by Atmospheric Drag
(2019-11-04)
The study of evasive maneuvers of spacecraft in the face of the danger of collision with space debris is essential and important today due to the growth of missions at low altitudes (LEO). Bodies that orbit this region are ...
RETROGRADE AND DIRECT POWERED AERO-GRAVITY-ASSIST TRAJECTORIES AROUND MARS
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2018-04-01)
A Gravity-Assist maneuver is used to reduce fuel consumption and/or trip times in interplanetary missions. It is based in a close approach of a spacecraft to a celestial body. Missions like Voyager and Ulysses used this ...
