On the Cover:LightSail captured this shimmering self-portrait from Earth orbit on June 8, 2015. In a June 10 press statement, Planetary
Society Chief Operations Officer Jennifer Vaughn summed up the project by saying, “This test mission has been a high-intensity, high-profile dress rehearsal. Through the ups and downs of our LightSail test flight, our members, backers, and supporters around the world have cheered us on. LightSail is a tangible symbol of citizen participation in space exploration. Behind the simple beauty of an image of a shiny sail in space lit by the Sun is the collective effort of tens of thousands of enthusiasts who got this project built, launched, and tested. This
successful test flight belongs to all of us.” The Planetary Society
