The Copernicus science cruiser upgrade.
Thinking of giving it 1-2 attachment/dock slots (at the center, or right in front and behind the middle section) where one could "dock" different modules:
- additional sensor module
- cargo module
- ring module (for subspace research)
- solar panels
- lab/hab module
With the ring module I'm contemplating several designs. The green bits are what would be rotating.
I got several options:
4-8 bits that rotate internally (ring is connected by a double connection)
4-8 bits that rotate externally
entire ring rotates (color is swapped for that one, the ring should be green, altough I guess the inverse rotation might be interesting too)
upper part of ring rotates
