solar sails

NASA is testing a sail system that uses solar energy to propel spacecraft through space.

A type of motivation that appears in science fiction has now proved feasible, bringing the dream of interstellar travel without our energy closer than ever.

NASA has just announced 12 futuristic designs that promise to bring people to new worlds, such as submarines on Titan moon and giant grid of asteroids.
