Mars is a society based on extreme shortages. Every material item takes on great importance because getting it there is so hard. People have electronic access to a great deal of stuff (not everything; internet is only updated periodically). This leads to a kind of asceticism. As my friend Kathy W. said, “Let’s paint this toothpick green and call it a Christmas tree.”
I have written several stories set on Mars and in its environs, and all share the same universe. The only one published so far is “Ancilla,” in Bull Spec.
