We haven’t seen SpaceX’s BFR — the rocket that it hopes will enable trips around the world, to the Moon, and, eventually, to Mars — actually take flight yet, but the company says it has already booked a private passenger for a trip around the Moon. No one has been there since Apollo missions ended in the 70s, but now, in a “world’s first” SpaceX is apparently taking reservations. Details like who is going and “why” are to be revealed during a livestream on Monday September 17th at 9 PM ET.
