I really would want You to ask important question. There are a lot of suggestions but let's talk about what SM needs most in Your opinion.
I'll start.
Most important things:
1. Something that will give players more things to care about:
Food, water, oxygen. It will also make players a little bit more focused on astronauts than ships. Of course ships will be also important but player will need to start care about himself.
It also gives You a lot more things to do. If You need many food then You will need to somehow automate it's mining. If Your faction will grow larger You will need to mass product Oxygen etc.
2. Something that will give more sense for exploring universe:
More celestial objects. Some of them should be rare and would be source of rare resources.
Also it needs some kind of feeling that You really explore galaxy not sectors with random skyboxes:

These two things are most important for me I think.
Rails are cool but they will not shape our currently shapeless gameplay. And SM gameplay really need to be shaped because currently it's:
Throw player somewhere near shop mid between stars and order him to develop untill He will be able to fight pirates.
Not much things to do isn't it?
