And it is a different business model today. During the space race, the question was “Can we get there?” Nowadays, for better or worse, it is “What is my ROI?”
Which is why I think there is no Moon Base Alpha today. What is on the moon that will turn a profit? Mining? Is there something in the moon that could justify the cost of extraction? People talk about going out to the stars from the moon, but is it the most economical way? Would a dockyard in Earth orbit be cheaper to operate? I’m not a rocket scientist, so I am not aware of what the advantages of a moon base would be.
For the private sector to truly take over space exploration, the companies must find it profitable. Nightmares of the Weyland-Yutani Corporation (Alien) and the Tyrrell Corporation (Bladerunner) come to mind, along with their depiction of corporate greed and ruthless exploitation, but privatization is the only viable way to push on and make progress. See, and this is why you still need government regulations, lest a ”wild, wild west” scenario develop.
Pioneers like Elon Musk have a bit of that early space exploration spirit in them, and although they must have a business plan that will eventually turn a profit, they are the chance takers who dare to go where the rest were unwilling to tread.
