                         Phobos and Deimos, satellites of Mars, research involving these 
                         moons has grown. These moons have a highly irregular shape and 
                         their orbits are close to Mars. In addition, Phobos and Deimos 
                         have a high potential to provide important information about the 
                         evolution of the Mars system as well as to contribute to a future 
                         manned mission to Mars. There have been some attempts to visit 
                         Phobos, none of them successfully and, to this day, no mission has 
                         been sent to Deimos. This work presents a detailed study of the 
                         main perturbations capable of altering the orbit of a spacecraft 
                         that orbits Mars, Phobos and Deimos, in order to understand the 
                         dynamics of spacecraft movement in the proximity of such bodies 
                         and seek cases where it is possible to find stable or near stable 
                         orbits around Phobos and Deimos for the maximum possible time. 
                         Strategic trajectories are presented that allow the spacecraft to 
                         visit both moons on a regular cadence, to approach or to cover the 
                         moons. All trajectory simulations are performed using the 
                         Spacecraft Trajectory Simulator (STRS). The considered 
                         perturbations on the orbital motion of the spacecraft are: the 
                         gravitational potential of Mars, expanded in spherical harmonics 
                         up to degree and order 80, the gravitational attraction of the 
                         Sun, the gravitational potential of Phobos and Deimos and the 
                         solar radiation pressure. For the perturbations due to Phobos and 
                         Deimos is used a polyhedral model to define the shape and mass 
                         distribution of these bodies.",
