This video shows brief highlights from LightSail 2, a crowdfunded space mission by The Planetary Society launching in June 2019. LightSail 2 aims to become the first spacecraft in Earth orbit propelled solely by sunlight. The goal is to raise 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.
