             abstract = "The powered swing-by maneuver is described by the parameters that 
                         define the orbit of the spacecraft and the ones that define the 
                         impulse applied. In this case the impulse is applied in the 
                         periapsis of the orbit around the body used for the close 
                         approach. It is important to consider that the values of the 
                         parameters involved in this maneuver are susceptible to errors, in 
                         particular the ones relative to the impulse, which can affect the 
                         energy variation and, consequently, the orbit obtained after the 
                         maneuver. This paper has the goal of studying several aspects 
                         related to the optimization of this maneuver, particularly 
                         verifying the sensitivity of the maneuver to these parameters and 
                         the effects that their errors make in a swing-by maneuver. The 
                         errors coming from the impulsive maneuver is the most important 
                         problem when considering powered swing-by, and it is usually the 
                         main reason to avoid this technique. Therefore, this paper will 
                         study the effects of these errors and compare them with the errors 
                         due to other variables involved in the close approach. It also 
                         shows the best direction to apply the impulse, as a function of 
                         the impulse magnitude and the regions of optimality of this
