Radiation pressure

Radiation pressure is the pressure exerted upon any surface exposed to electromagnetic radiation. If absorbed, the pressure is the energy flux density divided by the speed of light. If the radiation is totally reflected, the radiation pressure is doubled.

Solar sails

Solar sails, a proposed method of spacecraft propulsion, would utilize radiation pressure from the Sun as a motive force. Private spacecraft Cosmos 1 was to have used this form of propulsion.
