Sustainable Laser Propulsion System for Satellites
International Journal For Multidisciplinary ResearchThis research explores a sustainable approach to satellite self-propulsion through laser propulsion. The proposed self-contained system features an onboard high-powered laser directed at a large, reflective sail deployed by the satellite. Thrust is generated by the momentum transfer of reflected laser photons, enabling gas-free operation and ...
