Solar sail spacecraft. Computer illustration of a solar sail spacecraft flying past Jupiter. One of Jupiter's moons, Europa, is seen at upper right. The solar sail is a hypothetical design for a spacecraft which is powered by the pressure of photons (light) emitted from the Sun. Such a craft would require little fuel and could reach high speeds due to the lack of friction slowing it down.
