<p>This thesis investigates the feasibility of projecting ground-based laser power to energize a spacecraft  electrical bus via the solar panels. The energy is projected through a telescope, using modern optical  compensation systems, at controlled wavelengths. Research conducted on high-energy lasers has matured to the  point today, that the bulk of the power required by spacecraft on orbit can be projected from the surface of the  earth. With battery life being the greatest limitation on spacecraft lifespan, the ability to provide electrical power  from the surface to a satellite in eclipse with degraded batteries could mean multi-billion dollar cost savings by  extending the lifetime of current and future satellites.
