The Planetary Society’s privately funded LightSail spacecraft has arrived in Cape Canaveral, Fla., where it will be integrated with an Atlas V rocket scheduled to launch no earlier than May 6. The spacecraft is part of a secondary payload dubbed ULTRASat, which will fly aboard the classified U.S. Air Force mission AFSPC-5.

Bill Nye (The Science Guy), CEO at The Planetary Society, issued the following statement:

“Our LightSail cubesat passed every one of its tests and has been loaded into its launcher mechanism. I’m naturally happy and excited, but I admit, a bit nervous. We’ve been working to get a solar sail into space since I joined The Planetary Society Board in 1997. It’s quite a milestone. Deep breath, no turning back now, this baby’s on its own now. Here we go…”
