abstract = "With the advances of space-exploration technologies, a
long-lasting concern is finally being addressed: the deflection of
potentially hazardous objects (PHOs). Most recently, the first
mission of this kind was launched by NASAthe Double Asteroid
Redirection Test (DART). Nevertheless, it is estimated that a
great number of these PHOs are unattainable by means of current
chemical propulsion systems. With that in mind, this study
proposes the development of a heuristic technique for the search
of interception trajectories with the use of solar sails and its
application in determining a set of possible trajectories to
intercept hazardous asteroids. As a case study, a hybrid mission
inspired by the DART mission is proposed by using a solar sail as
means of propulsion after the initial chemical combustion. The
dynamics consider a model of the solar radiation pressure
acceleration as a function of the orientation of the sail. In
turn, the orientation is defined by the application of the
developed heuristic technique with the goal of defining
alternative trajectories compared to the original mission. These
trajectories result in different impact conditions and mission
durations. Although the use of solar sails breaks the symmetry in
the solutions, the results obtained offer the possibility of fuel
economy or even better deflection results by the achievement of
greater impact energy with the hazardous objects.",
