I’m trying to compile a list of all major and minor space centers across the United States — not just NASA sites, but also lesser-known research facilities and private launch sites if possible. Most of the sources I’ve found are either outdated or only mention the big names like Kennedy or JPL. I’m hoping for something more thorough and ideally something that has been maintained over the years, or at least still accessible online. If anyone knows a good resource for this kind of information, I’d appreciate it.
