Last man on the moon: 'I don't have a lot of confidence' in commercial space
"I don't have a lot of confidence in that end of the commercial space spectrum getting us back into orbit any time soon. I'd like to hear all these folks who call themselves commercial space tell me who their investors are. Tell me where their marketplace is. A commercial venture is supposed to use private money. And who are their users? Suppose we, NASA, have no need for their services. There's no other marketplace for them. So is it really a commercial venture, or is it not? Is it a group of guys who have stars in their eyes and want to be a big space developer? I don't know."
