Come sail away.
In a series of upcoming technology demonstration missions, NASA is hoping to prove that giant solar sails are a practical way to explore the cosmos, even though warp drive engines and rocket powered spacecraft make for better movie fodder.
Starting in 2015, NASA will be launching a series of three experiment driven missions, including one that will confirm the feasibility of using solar sails as a viable means of cheap propulsion.
