LightSail® is a crowdfunded solar sail project from The Planetary Society. Our LightSail 2 spacecraft, launched 25 June 2019, is the first spacecraft in Earth orbit propelled solely by sunlight. On 31 July 2019, we announced we had officially raised LightSail 2’s orbit by a measurable amount, showing that solar sailing is a viable means of propulsion for CubeSats—small, standardized spacecraft that are part of a global effort to lower the cost of space exploration.
