LightSail® is a citizen-funded project from The Planetary Society. We're sending a small spacecraft, propelled solely by sunlight, to Earth orbit.
In 2015, our LightSail 1 spacecraft completed a shakedown cruise. As soon as Spring 2018, LightSail 2 will launch aboard a SpaceX Falcon Heavy, and we will attempt the first, controlled solar sail flight in Earth orbit.
