Nice design! Just three issues: The flat spots on the g-ring will cause some weird stuff with the artificial gravity; so unless the interior floor of them is curved, if you put a ball on the floor it'd roll towards the pinch-points. Where's the docking point on the craft (either for it to dock to stations or for shuttles to dock to it), how do people board/leave it? A short range shuttle might be a wise idea, long-term mining missions could require EVA to the asteroid for any number of reasons (plus be a lot cooler for action scenes).

Thanks for the comment and for looking at my stuff. Anyway, to answer your questions.

Yes, the spinning habitat ring would cause issues since it's made out of 8 straight-edge pieces. While this design isn't exactly ideal, the colonists didn't have a lot to work with when they built this ship and just grabbed prefab habitats from their colony ship. Also, this was my first time trying to make a "Realistic" looking ship, and I didn't know 100% what I was doing. I've done lots of research since then, but I didn't feel like scrapping my old design since I still thought it looked cool.

All incoming and outgoing traffic goes by the zero-g hanger at the front of the ship. You can't see it as well from this angle, but there are lots of ports for incoming and outgoing craft. There are several hollow pylons leading from the habitat ring to the center of the ship for crew mobility, and another pair of pylons going the length of the ship if a human is ever required (though radiation protection is still recommended)

A ship this big doesn't usually dock with anything directly. A sorta umbilical chord docking boom can be extended from the hangar, though. There are also more than a dozen pilotable craft stored in the hangar (in fact, almost all of the craft can have a pilot, but most of them are controlled remotely instead.) In the event of total catastrophe, the habitat ring can be ejected into 8 separate parts, each of which has enough mobility to hopefully make it to be rescued.

Anyway, thanks for listening. I love talking about this kinda stuff.

I really should have indicated that craft take off and land from the hangar in the front but... that would require me to actually have some craft on hand to show. Maybe that'll be my next project.

Ah, didn't realize it that big. :D

Yeah, it's tough to show scale without windows or something like that. And, unfortunately, the windows on the habitat ring are not visible from this angle. Each of those little "boxes" is 5 or 6 stories tall.

Looks a lot better than the previous version. I think the only thing that stands out was mentioned above: the octagonal rotating part would give a heck of a grading near the corners. But that isn't a show-stopper or even impractical. At worst it would be a lack of comfort thing (who expects a mining ship to be luxurious?) or even unnoticeable depending on how the inside of the ring is laid out and allocated.

That's a good point. The floors on each of those sections probably curve up in order to compensate for the straight angles of the exterior construction.

again a very nice ship design

Thanks!

impressive redesign :3
