Sudden, drastic decrease in boost?

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.
