On the Cover: We’re at the Cape! The design changes, the do-overs, the tests and retests are all done and LightSail has arrived at Cape Canaveral, Florida, ready for its launch to orbit on an Atlas V rocket. This will be LightSail’s shakedown cruise; we’re checking all its systems in preparation for our primary mission in 2016. This moment has been years in the making and a sometimes wild ride. Thank you for riding with us.
