OSIRIS-REx will launch toward Near Earth Asteroid Bennu soon. In an early celebration of Asteroid Day, mission leader Dante Lauretta tells us how learning about asteroids may teach us about our own origins, and help us avoid a cataclysmic impact. Emily Lakdawalla has prepared a minute-by-minute timeline for the high anxiety July 4th arrival of Juno at Jupiter. Bruce Betts and Mat Kaplan invent a new kind of quilting party under a spectacular summer night sky.
