This blueprint produces 100 Space science pack per minute (white science)
This space platform is as cheap and simple as possible. Science production is absolutely stable, it produces exactly 100 science per minute without any dips or anything like that
It uses one second-level productivity module, which is what space packages are for, but the platform can work stably without it, there is just a small chance of getting a short-term production dip
