It's illegal for private enterprise to go into space. 互联网档案馆的存檔，存档日期1999-02-18.
U.S. law regulates private space launches, and the current law is quite unreasonable. A private company wanting to build and launch a rocket faces a mountain of red tape and very long lead times for getting approval from the government. However, although these problems add a tremendous amount of cost to private space launches, there are no laws that prohibit private space launches.

Launching was for many years an enterprise that was run by a de facto partnership of NASA and the companies from which NASA bought launchers and launch services. NASA proposed to put an end to that enterprise in the 1980s; it sought to enthrone the shuttle as the nation's commercial, as well as government, launcher. The prospect of erecting a private sector launch industry alongside the NASA shuttle was discussed, but it did not become a reality because the shuttle was too tough a competitor for private vehicles. Only the grounding of the shuttle after the Challenger accident allowed the commercial launch industry to get started".

For decades after that first launch, space flight was a government monopoly. Even when private companies started going into space in the 1990s, it was only as providers of launch services to send commercial and government satellites into orbit. Now, all that is changing as private enterprise takes over space exploration in a manner not seen since the early days of the Hudson's Bay Company.

Although some governments funded vehicle development in different ways, there were no vehicles that were not the product of some form of fairly direct governmental support. Even Ariane, the most "commercial" of launch vehicles, was commercial in operation only, not in inception and development, and could easily call on government support when things went wrong.

U.S. law regulates private space launches, and the current law is quite unreasonable. A private company wanting to build and launch a rocket faces a mountain of red tape and very long lead times for getting approval from the government. However, although these problems add a tremendous amount of cost to private space launches, there are no laws that prohibit private space launches.
