There are likely going to be channels in game. Social interactions are vital for a game like DU. But maybe you'll need to have an element in your ship or a device in your inventory, who knows. 

I'm ok with whatever it will be called, as long as I have plenty of it 

HAIL HYDRA. ONE THREAD CLOSES, TWO MORE SHALL ARISE!

Personally, I generally reserve my time for when I can actually get my hands on something, before I talk about it. This week I've made an exception.

I'm going to use two accounts or more to build up a quick production factory somewhere underground not too far, but not too close to the (a) central starting area. 
 
I'm then going to start a space-taxi service, flying newcomers to nearest planets out of good will, and older toons for a price.
 
Then when all of my research and autonomous excavation finishes doing all that, I'll retread back into the void of space and start a tight-knit colony of Free Miners, surviving solely in space.

I see, something like this then
 

Well, the thing is the game is going to sport a physics engine. So, if you were to put battleship thrusters onto your jetcraft, that would need a battleship's power core to make it go live, then you would need a battleship's fuel supply for such a beast of a thruster. Lift can be emulated with underbelly thrusters, but, if you were to add a battleships engine to a jet, that would increase its mass, therefore its need on certain underbelly thrusters. Which is my strong belief that a battleship won't land on surface, as gravity will be too much of a hassle to deal with on taking off a planet. That being said, a battleship would indeed require a certain fuel source, either it be anti-matter, fusion/fission reactors or in some semi-warp kind of drive situation, dark energy. All these come at a cost and functions of course. So yeah, there could be different types of engines and fuel, but the real question would be if you can afford the ship itself to run it. I personally expect peple to opt for fusion cores, as hydrogen is in abundance in the universe. Comets, planets, even in vacuum you can find hydrogen. But anti-matter or dark energy, well, quite the challenge, as those things don't usually come easy into being made. 
 
 
 And I don't seem to grasp on the artificial mass, if someone can explain it to me, it would be great

Unlikely that any spacecraft thats not designed to be buoyant in a gas giant would float.Considering that the (predicted) density of /metallic/ (solid, it doesnt get much denser for it) hydrogen is 0.8g/cm³.
Where as water has 1g/cm³, iron has 7.8g/cm³ and aluminium 2.7g/cm³
So a spaceship will have a higher average density than any fluid in a gas giant and thus sink.

I'm hoping it becomes possible to recreate the space-born lifestyle illustrated in Orson ScottCard's formic invasion trilogy - surviving entirely on supplies from space depots where you go to sell your ores and minerals.
