Abstract

This invention relates generally to method and apparatus for solar-boost assist and solar-sail assist by a mini-optics light concentrator system utilizing a dynamic ensemble of mini-mirrors. In the boost phase of a rocket ship launch, the system focusses solar energy into the rocket chamber to raise the temperature of the propellant and increase the impulse. In the mid-course phase, the system focusses solar energy onto the rocket's solar sail to increase the thrust. In both cases, the system reduces the weight of the rocket by providing a weightless source of thrust.
