Trajectory by Light: Computational Dynamics of Solar Sails

Solar sails present a promising propulsion concept for deep-space exploration by harnessing photon momentum transfer as a continuous thrust mechanism. In this project, we develop computational simulations to investigate the dynamics of solar sail spacecraft under varying sail geometries, material reflectivities, and orientations relative to solar radiation. Using numerical integration techniques, we model sail trajectories for interplanetary transfers and evaluate the long-term stability of photon-driven propulsion. Preliminary results highlight the potential of solar sails to achieve sustainable propulsion without reliance on conventional fuel, while also revealing critical dependencies on sail design parameters. This work positions solar sails as a compelling area of computational astrophysics research, bridging theoretical modeling with applications to future space missions.
