NASA built the space program with the help of: Private industry and Nazi engineers "liberated" from Germany. I've read some libertarians argue that the space program was a complete waste of time and money. I don't agree with that, since the USSR was a threat and there was no way the US could not get involved. It was a matter of national security at the time. Now, we are starting to see space become privatized somewhat. There is a company in California that has a contract to launch cargo rockets to the ISS and of course there is Bigelow Aerospace, the guys who wanna put a hotel in orbit. And Virgin Galactic as well. A mix is necessary and I think what is being described as libertarian is an example of some of the more extreme ideas that have come out of that philosophy. Not everyone who is libertarian falls into that mold.
