In orbital dynamics, minor bodies are those that have size (and mass) much smaller than at least one of the other bodies (called primaries) of the system that belong to. One case very common in astronautics is the case of a spacecraft traveling within the sun-earth-moon system. This kind of characteristic makes the dynamics of the system to present some peculiarities. One of them is the f…
Artificial satellites are nowadays part of daily life as well instruments for advanced research in fields such as geodynamics, astrophysics of the solar system (atmosphere composition, magnetic field of planets), astrobiology ( water content and other materials essential to life as we know it), cosmology (Hubble and its new generation missions), communication satellites, weather and terri…

Autonomy in space applications has gained progressive attention. A great motivation is in using space for economic purposes. Asteroid missions do not escape that trend, especially when considering the economic motivations such as asteroid mining. However, whether it is for mining asteroids or increasing the capabilities of science missions, much still needs to be done for the complete aut…
The gravity assisted maneuvers were development to change the spacecraft trajectory using an approach to a massive body, like a planet. The planet gravity field transfers energy to the trajectory, resulting in changes in the direction and velocity of the spacecraft. These maneuvers save propellant and reduce the mission cost. Also, it can be implemented to increase the decay in SmallSats …
Recent space missions show interest in the exploration of lunar satellites of our solar system taking advantage of stable points / orbits, for example, to perform maneuvers with minimum fuel consumption. It is known that when considering in the potential due to non-uniform mass distribution of the central body only secular terms up to the order of coefficient J2, the system of equations d…
The objective of this work is to study orbital maneuvers that can be performed by a passage of the vehicle by a celestial body and with the help of cables or impulsive propulsion. It will be considered that the space vehicle can move in the three dimensional space, thus allowing the change of the orbital plane. Two main options will be considered: i) "propelled Swing-By", which consists o…

The present proposal is structured according to the requirements of the BEPE´s scholarship. The main motivation for the research is the search for robust control techniques and algorithms, capable of being implemented for guidance and control of autonomous spaceplanes in interplanetary missions to perform aerogravity assist maneuvers, with and without propulsion. The goal of the proposal …
The study of orbital maneuvers with minimum fuel consumption in space missions are of great interest in Celestial Mechanics. Therefore, the objective of this work is to study a combination of gravity-assisted maneuver combined with the application of continuous low-thrust propulsion to a spacecraft. In the pure gravity maneuver the spacecraft passes close to the celestial body and uses th…
The purpose of this project is to develop a study concerning the roto-translational dynamics of an asymmetric rigid body, considering this body under the influence of a central gravitational field. A Hamiltonian theory will be studied as a perturbed form of the Keplerian motion and torque-free rotation. A chain of canonical transformations will be considered: the elimination of the nodes …
