Outer space capitalism: The legal and technical challenges facing the private space industry

The private sector may need the Outer Space Treaty to be updated before it can make any claims to celestial bodies or their resources.

  • The Outer Space Treaty, which was signed in 1967, is the basis of international space law. Its regulations set out what nations can and cannot do, in terms of colonization and enterprise in space.
