Shallow Encounters' Impact on Asteroid Deflection Prediction and Implications on Trajectory Design
Rodolfo Batista Negri, Antônio Fernando Bertachini de Almeida Prado
Analytical approximations are commonly employed in the initial trajectory design phase of a mission to rapidly explore a broad design space. In the context of an asteroid deflectio…
Optimal transfers from Moon to halo orbit of the Earth-Moon system
L. B. T. Santos, Allan Kardec de Almeida, P. A. Sousa-Silva +4
In this paper, we seek optimal solutions for a transfer from a parking orbit around the Moon to a halo orbit around of the Earth-Moon system, by applying a single maneuver an…
Numerical investigations of the orbital dynamics around a synchronous binary system of asteroids
L. B. T. Santos, Allan Kardec de Almeida, P. A. Sousa-Silva +5
In this article, equilibrium points and families of periodic orbits in the vicinity of the collinear equilibrium points of a binary asteroid system are investigated with respect to…
Strategies For Non-Planar Configurations Of Geostationary Tethered Collecting Solar Power Satellite Systems
F. J. T. Salazara, A. F. B. A. Prado
To collect additional solar energy during the hours of darkness and to overcome the limited Terrestrial solar power due to the diurnal day night cycle, the concept of a Geostationa…
Using Upgraded Versions Of Close Approach Maneuvers As Transportation Solutions For Deep Space Missions
Antonio F. B. A. Prado
Gravity-Assisted maneuvers have been used as a technique to reduce fuel consumption in deep space missions for several decades now. It opened the doors of the exterior solar system…
