This futuristic NASA ship could reach the edge of the solar system

It took the Voyager 1 spacecraft over three decades to leave the solar system, and scientists still aren't sure when it did.

We need a new method of propulsion that will transport spacecraft faster than ever before. NASA is one of a few agencies developing a new way to sail through space - on the power of the solar wind.
