Space 1.0 is the industry we all grew up with: rockets to the Moon and billion-dollar government contracts. In Space 1.5, the launches are commercial and so are the payloads. “NewSpace” is probably Space 1.5.1.
“NewSpace,” the privately funded world of such visionaries as Elon Musk and Richard Branson, is probably Space 1.5.1. Branson, Musk, and Paul Allen have poured money into their projects because 1) they have it and 2) they’re committed to the dream, not because they expect ROI anytime soon.
