Is there a 'hidden' max stack size with satellites using you're stacked recipes? Both to manufacture and use in the red silo I guess. I was using stacksize of 100 but, the resulting satellites stack size is only one!

I may have found another mod that fixes this problem. Deadlock's Stacking Beltboxes Compressed Stacksize Override mod by zaflis stacks satellites to what the setting on your beltboxes mod is set at.

Satellites usually only stack in "ones". Launching a normal "satellite" return 1000 space science packs.

You will want to be careful about launching "space science" as only a single stack of fish (200) can be returned. So the most "space science" you want to launch should be 200.
