To me, it's a no-brainer that the Earth-Moon L1 location is a strategic locale, sort of a forks of the Ohio in local space. I've seen some proposals to put some long-term station there, but has anyone really "done the math" and come up with a fully thought out plan?
Such a plan should encompass most of the following:
- A compelling rationale.
- Drawings backed up by preliminary engineering calculations.
- Some idea as to how it would be launched/assembled/positioned at L1, and
- Some notion of how it would be financed.
Manned, unmanned, or hybrid (i.e., visit occasionally) is immaterial, so long as the plan involves a long-term presence.
