A solar sail is a form of spacecraft propulsion that uses the pressure of sunlight for thrust, eliminating the need for conventional fuel. The concept involves a large, reflective sail that captures the momentum of photons emitted by the Sun; even though these particles are massless, their impact transfers momentum to the sail, propelling the spacecraft. Solar sails allow for continuous acceleration over long periods, making them particularly suitable for missions requiring long-distance travel where traditional fuel would be impractical due to mass and depletion concerns. Notable experimental and theoretical solar sail missions include the Japanese IKAROS project, which successfully demonstrated solar sailing in 2010, and the Planetary Society’s LightSail project. These developments underscore the potential of solar sails to enable more efficient, cost-effective space exploration and even interstellar travel in the future.
