Re: [Space, Spaceships] Mars Semi-Cycler?
Here is an enlarged version of the Perdue-class Semi-Cycler.

User Notes: The modular Vehicle Docks can hold two SM+7 (300-ton) auxiliary craft, usually atmospheric craft used as orbital taxis. (Modularity allows the customized docks to be swapped in and out as required.) If an auxiliary craft has habitat modules installed, the crew usually stays aboard their ship to stretch life support; otherwise they travel as passengers or in hibernation chambers.

Please note that: - While this ship contains no superscience systems, it is listed as TL9^ because the Orbital Taxis it uses have a reconfigurable fission reactor/NTR ram-rocket to power its VASMIR drive and liftoff from Mars. (I'll post its design later.)
- The control room remains the same size (SM+8 system) and the crew habitats have been moved from the center and rear hulls to the front hull core.
- While the semi-cycler still launches in a 2-year free return trajectory for safety reasons, its doubled ∆V allows it to perform the Mars Orbit burn itself, so it can loiter in Mars orbit until the proper return window occurs.

Reason: Tweaked design for auxiliary craft changes.
