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…
Dynamics Around an Asteroid Modeled as a Mass Tripole
L. B. T. Santos, L. O. Marchi, P. A. Sousa-Silva +3
The orbital dynamics of a spacecraft orbiting around irregular small celestial bodies is a challenging problem. Difficulties to model the gravity field of these bodies arise from t…
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…
Analysis of the dynamics of a spacecraft in the vicinity of an asteroid binary system with equal masses
L. B. T. Santos, P. A. Sousa-Silva, M. O. Terra +8
In this work, we performed a dynamical analysis of a spacecraft around a nearly equal-mass binary near-Earth asteroid with application to the asteroid 2017 YE5, which is also a pos…
A Particle-Linkage Model for Elongated Asteroids with Three-Dimensional Mass Distribution
Leonardo B. T. Santos, Luis. O. Marchi, Aljbaae Safwan +3
The goal of the present paper is to develop a simplified model to describe the gravitational fields of elongated asteroids. The proposed model consists of representing an elongated…
Influence of Apophis' spin axis variations on a spacecraft during the 2029 close approach with Earth
S. Aljbaae, J. Souchay, V. Carruba +2
Tumbling asteroids belong to a small group of objects, whose angular velocity vector is unaligned with any of its principal axes of inertia. This leads to challenging efforts to mo…
First approximation for spacecraft motion relative to (99942) Apophis
S. Aljbaae, D. M. Sanchez, A. F. B. A. Prado +4
We aim at providing a preliminary approach on the dynamics of a spacecraft in orbit about the asteroid (99942) Apophis during its Earth close approach. The physical properties from…
