Aerospace

In a fantasy, I imagine what a gateway station orbiting our moon could look like, or an environmentally clean supersonic airplane and perhaps one of the next orbiting space stations. On one of those space stations, there may be crew compartments, laboratories, a Long Range radio transmitter/receiver, a science station, mined sample storage, transfer facilities, and whatnot.
3D design tools like Blender offer a means of transforming mere visual fantasies into tangible imagery.
