Photon Sailor aims to create a realistic photon-sailing experience in KSP. A photonsail, also known as solar sail or laser sail, allows a spacecraft to propel itself using radiation pressure from the sun or laser transmitters, removing the need to carry any reaction mass and simply using the deflection of photon energy to provide thrust. The acceleration gained from solar radiation is extremely small but can be applied over a long period of time to reach extremely high speeds, given a la
