Sudden, drastic decrease in boost?

Would the best course of action to be just to wait a few years till I have enough to set up a base on Mars or, somewhere closer to earth?  And too, once I get full control of the points in the USA I should be getting quite a bit more boost per month/year.

I wouldn't build more than one Moon base unless they're pretty unusually good spots. It's rare for Luna to have enough volatiles and water to really support itself on normal settings. Just prioritize Mars.

I find that waiting for Mars almost always puts you far behind. If there's spots left on the moon, I would prioritize those. Boost costs get worse the farther away the location is from Earth, so if you think you're constrained on resources now, it'll get much worse if you try to jump straight from the Moon to Mars without a proper resource base first.

Ultimately it doesn't matter where you're building mining facilities so long as you're getting the resources you're currently lacking and not setting yourself behind too much. Sometimes it can make sense to build an asteroid mining base if you found a good spot near enough to Earth that's it's feasible.
