LightSail 2's Legacy

For centuries, people have dreamed of traveling the cosmos using solar sails.

In 2019, The Planetary Society's LightSail 2 will help make that dream a reality by attempting the first, controlled solar sail flight in Earth orbit. The spacecraft was made possible thanks to the generous support of space enthusiasts from around the world.

We're advancing space science and exploration.
