. It might be worth investigating though. We know more than 1 "vessel" can't mine together, but as units stack will they perhaps work together.

As there aren't displayed in your own score (like remote mining if memory serves), the resource generation abilities are unlikely to be included when computing how much you give when involved in a trade agreement.

By the looks of it, only the resources produced at a facility actually alter your score, and are taken into account by the trade treaties, but I may be mistaken here.

Only one ship/base works for remote mining, with unlimited individual extractors on the ship.

But 3 satelites, one each with mineral, organic, and rad extractors will work. No more than 3, and 2 or more mineral sats won't work. I just figure the game is hard coded to allow a specific ideal of remote mining.
