Solar sailing is a novel way of propelling space probes. It takes advantage of the acceleration produced by photons impacting upon a body, the so-called Solar Radiation Pressure (SRP). Unlike traditional thrusters, the acceleration is continuous and unlimited. We are interested in understanding the dynamics of a spacecraft endowed with a solar sail in the Earth-Moon system. The most commonly used model is a modified version of the Restricted Three Body Problem (RTBP) which includes the effect SRP. Instead, We use the Quasi-Bicircular Problem (QBCP) as a basis model which also includes the gravitation effect of Sun. The resulting model depends on two parameters describing the effectivity and the orientation of the sail. Moreover, the system is a Hamiltonian periodic perturbation of the RTBP. Our goal is to understand how the simplest invariant objects change with respect the sail parameters. We focus on the periodic orbits that replace the Lagrangian equilibrium points as well as the resonant orbits that come from the Lyapunov and Halo families related to the mentioned equilibria.
