Mat Kaplan visits Cal Poly San Luis Obispo for a last, clean room visit with LightSail 2, the Planetary Society’s solar sailing cubesat.  While there, Mat also talked to attendees at the Cubesat Developers Workshop, including the creator of the tiny “Pocket Rocket” engine for small spacecraft. LightSail2 is now at the Air Force Research Lab for launch preparation, as we hear from Bruce Betts in this week’s What’s Up.
