NASA has announced that an experimental propulsion system that needs only energy from sunlight appears to produce sufficient thrust to power spacecraft. This means that, once a spacecraft is in orbit, it will be able to accelerate away from the earth to the edges of the solar system, without fuel. This means that travel throughout the solar system is going to become much more possible and far cheaper.
