This effort will aim to demonstrate the feasibility of directed-energy propulsion through a combination of computational simulations and prototype testing. The project will model the interactions between lightsail material and a laser beam that can be pointed at the sail to propel the spacecraft. The results of the modeling will be used to fabricate an optimized sail for testing with a 30W laser. A successful demonstration would pave the way for ultrafast spaceflight within and beyond the solar system.
