SpaceX founder and CEO Elon Musk has been pledging to send tourists to space ever since he started the company in 2002. On September 17, 2018, the visionary came one step closer to fulfilling his promise by signing up his first passenger – Japanese billionaire and entrepreneur Yusaku Maezawa. If all goes according to plan, in 2023, Maezawa will become the first passenger and private astronaut to travel to the Moon. He will also join the elite group of just 24 humans who have been fortunate enough to see Earth’s satellite up close.
