SpaceX is planning to send two private individuals on a trip around the moon sometime next year. In a phone briefing today, CEO Elon Musk gave details of the mission, which would use two of SpaceX‘s long-awaited technologies: a crew-rated capsule, the Crew Dragon, and the high-powered Falcon Heavy rocket. The two mystery astronauts will be packed inside the capsule, stacked on top of a Falcon Heavy.
