While significant, the first LightSail flight did little more than prove the photon-powered craft was viable. This flight will take things a step further. The team plans to fly the craft in an orbit around the Earth and to test out its maneuverability. Ultimately, the Planetary Society hopes to use the LightSail to propel Cubesat satellites through space. “This is history in the making—LightSail 2 will fundamentally advance the technology of spaceflight,” said Bill Nye, CEO of The Planetary Society.The Falcon Heavy rocket is scheduled to launch from the Kennedy Space Center on June 24th in a four-hour window that begins at 11:30pm ET. If all goes according to plan, in addition to carrying LightSail 2, this will be Falcon Heavy’s first night launch.
