There's a new space billionaire, and this one is not interested in launching rockets. His name is Jed McCaleb, a US software developer who made his fortune in blockchain development and cryptocurrency. With an acquisition last week of a small space company named Launcher, McCaleb has shown he is serious about building a space station in low-Earth orbit.
McCaleb's space habitation company, Vast, emerged publicly last fall with a plan to build space stations that featured artificial gravity. This was significant because NASA and most other space agencies around the world have devoted little time to developing systems for artificial gravity in space, which may be important for long-term human habitation due to the deleterious effects of microgravity experienced by astronauts on the International Space Station. Vast boasted three technical advisers who were major players in the success of SpaceX—Hans Koenigsmann, Will Heltsley, and Yang Li—but did not offer too much information about its plans.
Now it seems clear that McCaleb is genuinely interested in making a run at this. An early pioneer in blockchain technology, McCaleb created Mt. Gox, the first major Bitcoin exchange. He is estimated by Forbes to be worth $2.5 billion and has vowed to invest at least $300 million into Vast Space as it seeks to develop space stations.
