Solar Sails to Use Solar Winds for Spacecraft Propulsion
Solar sails were once thought to belong in the realms of science fiction. Huge canopies of lightweight tin foil catching the solar photon breeze, slowly allowing spacecraft to cruise around our solar system propelled by the small but continuous radiation pressure. Recent years however have shown that solar sail spacecraft could be engineered in reality, and a new solar sail invention from the Finnish Meteorological Institute could push this goal one step closer. Rather than using solar radiation pressure, this new concept makes use of the highly charged particles in the solar wind to give the craft its propulsion. Additionally, through radio wave electron excitation, the system may amplify the solar wind acceleration effects, giving the spacecraft a "boost" function…
