Scientist might be able to build light-powered spaceship

Scientists might be able to build a spaceship that can fly with no fuel.

NewScientist.com says they discovered that graphene - a super-strong, super thin material made from carbon atoms - will move when it's hit by light, just light.

So if you made a spaceship out of it, it would eventually build up enough momentum in frictionless space that it would be propelled just by sunlight.
