The Planetary Society introduces LightSail 2, a solar sailing CubeSat that uses the pressure of sunlight for propulsion. LightSail 2 is the successor to LightSail 1, which completed a successful test flight last year. The new spacecraft will launch with Georgia Tech's Prox-1 satellite aboard a SpaceX Falcon Heavy rocket. This video showcases recent LightSail 2 sail deployment tests at Cal Poly San Luis Obispo.
