An Israeli-built moon lander aiming to become the first privately-funded mission reach another planetary body rocketed away from Cape Canaveral on Thursday night aboard a SpaceX Falcon 9 rocket, riding piggyback with an Indonesian communications spacecraft and an experimental U.S. Air Force space surveillance microsatellite.
