Here's a SCED plan that splits the cost of building the Craterscope Structure over two turns (with a side of Ore Electrolysis) while also building the Mars base and doing lots of Craterscope research. It also holds back on spending our Reserve so we still have the budget to continue (and try to finish) Craterscope research next turn.

@Lightwhispers A few errors I spotted in your Plan: Since you're not using an Outside Dev Dice, the die on Craterscope Atmospheric Analyzer should only cost 10C, not 20C. Voyager Visitation is at 131/150, not 102, and so one die on it is 87% likely to complete. (My fault; outdated Array.) And you're paying the Pathfinder days cost for going to Mars twice; we only have to pay it once per turn, meaning you have 13 more Pathfinder Days to work with.
