We're into necessary evils at that point. If you want to mine a distant planet, youve gotta suck up flying there.
Long haul is never fun.
Take this as an example of how id use it, for context.
4 man mining/survey team.
Load the frieghter, everyone aboard. Dull long haul flight ensues, everybody yawns, but you get there.
You de bus. One person gets into the atmospheric scout you brought with, goes looking for likely prospecting locations, while the other 3 throw a little outpost together.
Surveys ensue, and mining.
Eventually, you have enough mined ore stored that you want to ship it back.
With auto turrets, one person shuttles the ore back, while the other 3 keep mining/surveying. One person drops the ore off, yawns, and flies back, knowing its someone elses turn next time.
Without auto turrets, all get aboard, fly back etc, knowing they all need to do it every time.
