Meant to be a more realistic spacecraft model, not realistic in terms of photo-realistic, but something that may be built in the near future, for a mars mission or such.
This is a generic spaceship, it does not have any insignias or copyrighted material nor does it exactly match any existing or concept spacecraft.
It has four blocks near the front that are intended to rotate, they are split into two objects (blocks and the handle shaped details).
The solar panels are not intended to rotate.
Blender's bevel modifier may have created some coincident vertices.
Origins may not be 100% right.
OBJ format probably put all origins in one spot.
Objects names most probably were removed when the file was exported.
Edge split has been applied in some areas, edge split uses coinciding vertices to make a sharp edge. This will make it harder to modify in those areas.
No real world scale or LOD variants.
You will have to re-make glow effect on engine.
