The Complete Guide to Space : Space Science and Technology and the Future of Laser‑Driven Solar Sail Propulsion
A single 5-megawatt ground-based laser could trim Mars-bound travel time by up to 50% - turning years into months - and slash launch mass dramatically. In my experience, the combination of high-power photonic thrust and ultra-light sail materials offers a practical path to faster, cheaper interplanetary missions, especially as governments
