The Planetary Society today announced the first of its LightSail spacecraft will embark on a May 2015 test flight. Funded entirely by private citizens, the solar sail satellite will hitch a ride to space aboard an Atlas V rocket from Cape Canaveral Air Force Station in Florida. The mission will test LightSail’s critical functions, a precursor to a second mission slated for 2016. That second flight will mark the first controlled, Earth-orbit solar sail flight and ride along with the first operational launch of SpaceX's Falcon Heavy rocket.

“There's an old saying in aerospace, 'One test is worth a thousand expert opinions.’ After six years of development, we're ready at last to see how LightSail flies," said Bill Nye (The Science Guy), CEO at The Planetary Society.
