Which star trek ship classes (just the design, layout, and size of them, but without any of their actual fictional technology) would be practical and useful for modern day NASA/ESA/etc. space agencies to use for ISS, mars, moon, interstellar, etc. supply and exploration missions, and why? They can be any ships from any species.

Note: The star trek technology wouldn't be applicable, just the look of the ship, so the warp nacelles wouldn't actually be for a warp engine, they would just be there for the design of it and would actually be used for something else, possibly for storage space, for example.
Some important things to consider might be:
Storage space
Science labs
Medical facilities
Crew quarters
Shuttle bays/docking ports
Communications equipment
Computer system
Artificial gravity source, or weightless gravity environment
Kichens and food storage areas
Recreation facilities
Hull design suitable for towing large equipment and having easy shuttle access
Power source and engines
Engineering, jeffries tubes, and maintenance facilities and equipment
