LightSail is a nationally funded project by The Planetary Society to send a small spacecraft, powered solely by sunlight, to Earth's orbit.
The racket's two side runners still carry their branding from the April Arabsat-6A mission, where both boosters successfully flew back to Cape Canaveral for upright landings. The central core is pearly white, has never flown.
You can see tonight's launch live on our website at planetary.org. SpaceX usually starts its webcast about 20 minutes before recording. More information can be found on our LightSail 2 mission page and what we can expect when LightSail 2 is launched in the space article.
