One ship can have multiple robominers. A base is probably better, since you pay less maintenance on it, and it is bigger.
A pure-mineral ship and a pure-organics ship cannot both work in the same sector.

Planetary value goes down 1% no matter how many miners you're using at once.

Sats can stack one sat for each of the resource types, but not stack on a specific resource.
IE: Having a mineral sat works. Adding an organics sat also works. Adding a second mineral sat to the stack does not work.
