It’s amazing that this is happening considering how expensive it is, the cost of developing the technology and building the prototype from scratch. It’s literally going where no man has gone before, considering the money isn’t coming from NASA or the American taxpayers but from one very wealthy person! If I were the leadership in Moscow or Beijing I would be very concerned about what Musk is doing, because if he’s successful, the Chinese will be obligated to duplicate the effort, lest Mars be colonized by Americans. The Russians can’t even afford to play the game. The combined financial resources of Musk and Bezos and the technical experience of NASA has opened the curtain on a new era of space exploration and demonstrated how to pay for it.
