LightSail 2 will launch aboard a SpaceX Falcon Heavy no sooner than June 24th. Keep an eye on the site for the latest news and a link to the live stream when it’s almost time for takeoff.

LightSail 2 is not humanity’s first success at sailing on sunbeams. That honor goes to IKAROS, a roughly 50-foot by 50-foot Japanese spacecraft weighing hundreds of pounds.

LightSail will then tack like a sailboat in order to raise its altitude, which will earn it the distinction of being the first spacecraft to sail to a higher orbit around our planet.

These ultrathin sails could achieve speeds never before imagined. But building and testing these sails is a complex undertaking. “The lightsail will travel faster than any previous spacecraft ...

LightSail 2 unfurled its 32-square-meter (344-square-foot) solar sail on July 23, around one month after it was deposited into low Earth orbit by a SpaceX Falcon Heavy rocket.

LightSail 2 has already built up a gallery’s worth of images from its 450-mile-high orbit, including glorious views of Earth’s ocean-blue and cloud-white disk.

"The lightsail will travel faster than any previous spacecraft, with potential to eventually open interstellar distances to direct spacecraft exploration," Caltech's Harry Atwater, the Otis Booth ...

LightSail 2 is the first steerable solar sail ever launched into orbit around Earth. Its solar sail is about the size of a boxing ring, and made from a thin mylar material.

According to the scientists behind the project, LightSail 2 has successfully raised the highest point of its orbit, and it did so without any conventional built-in propulsion system.

One week after the Planetary Society's experimental LightSail spacecraft spread its solar sail, satellite watchers reported Sunday that it fell from orbit and broke apart in Earth's atmosphere ...

LightSail Energy has appointed two industry veterans to its executive ranks, as the energy storage startup looks to ramp up sales of its technology. It represents a new phase and test for the five ...
