Yeah sure you dont need wings because there is no air in space but at the same time if you say i dont put wings then you can also go and say there is no friction in space so why have a shape at all ?
In space, theoricaly, a sphere would be the best design but between you and me who wants to fly a sphere huh ?
so it's more a matter of how you would like it to look than how realistic it you want it to be in my mind.
