Flight by Light for CubeSats
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.
For updates on LightSail and other Planetary Society news and activities, be sure to sign up for our monthly newsletter, The Planetary Post.
