Default Re: Good ways to limit space travel?

It is not necessary to make the third star impossible to reach, only to make it to big an investment for the return. Suppose recent engine upgrades can leave more holdspace.

Perhaps scouts had been there before but no attempt has been made to exploit it.

Another possibility. The fuel you use is only sufficient for a one way voyage at that range. The only reason you were able to settle the second star's worlds was that ore deposits were discovered making it possible to refine fuel for the return voyage on site. Once that was done colonies were gradually built. Now unmanned probes have discovered similar ore deposits on the third star's planets.
