Mars colonization ship fully loaded
This diagram shows the "core vehicle" fully loaded after several waves of colonists have used it for transport to Mars. The core vehicle cycles between Earth and Mars. Each group of colonists comes from Earth with a transfer vehicle (biconic entry vehicle) and a cargo module. The transfer vehicle is later used one-way to transport the colonists from the core vehicle to the Martian surface. The cargo module remains attached to the core vehicle to expand its habitable volume and provide additional material for the next wave of colonists.
Again, this is just to establish whether or not I can get the images to display. I'll present this over on HabitableZone Space Science with full commentary after I've worked the bugs out.
