abstract = "This work includes analytical and numerical studies of spacecrafts
orbiting two binary asteroid systems: 1999 KW4 and Didymos. The
binary systems are modeled as full irregular bodies, such that the
whole evolution of the results will show the impact of the
irregular gravity field in the lifetime and dynamics of the
spacecrafts orbit. The equations of motion of the binary system
and the spacecraft are derived from Lagrange Equations. The solar
radiation pressure is consired in the dynamics of the
spacecraft.Two distinct methods are used to search for stable
orbits around the binary systems. One is called the grid search
method, which defines the main body as a point mass to estimate
the initial state of the spacecraft based on a circular Keplerian
orbit. The second method is the search for periodic orbits based
on zero-velocity surfaces RESUMEN: Este trabajo presenta estudios
anal´\ıticos y num´ericos sobre naves espaciales en ´orbita
en torno a dos asteroides binarios: 1999 KW4 y Didymos. Se modelan
los sistemas binarios como cuerpos irregulares, de modo que la
evoluci´on muestre el impacto del campo de gravedad irregular
sobre los tiempos de vida y la din´amica de la ´orbita de la nave.
Se derivan las ecuaciones de movimiento del sistema binario y de
la nave a partir de las ecuaciones de Lagrange. Se considera la
presi´on de radiaci´on solar. Se buscan ´orbitas estables en torno
a los sistemas binarios mediante dos m´etodos. El primero se
conoce como el m´etodo de b´usqueda en la malla, y considera al
cuerpo principal como punto masa para estimar el estado inicial de
la nave a partir de una ´orbita Kepleriana circular. El segundo
busca ´orbitas peri´odicas mediante las superficies de cero
velocidad.",
