 And they have another flight coming sometime in the next four weeks, I would say, the fifth flight. And the thing about this rocket is that unlike the Saturn V, it is being designed from day one to be completely reusable. And so that means that the cost of flying heavy payloads into space is going to go down exponentially to be very small. And it's not unreasonable for SpaceX to get that done because they know how to do reusable things.
