Billionaires in space: another Heinlein bullseye?

Most discussion of Heinlein has focused on Nehemiah Scudder, but could Delos D Harriman also turn out to be real?

Billionaire business men are certainly far more into space activity now than they were in the 1960s, when NASA had pretty much a monopoly.

If you don’t have your own space program, are you really even a billionaire…?

Seems the Moon isn’t big enough for today’s Harrimen. Someone should really warn the Martians.

This guy, though, seems singularly focused on the Moon:

Altemus explained in an interview with TechCrunch that Intuitive Machines is uniquely positioned to support lunar missions and eventually a lunar economy, not just as a contractor for NASA or the Pentagon but as a full-fledged commercial space services company.
