My Mars has 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.”
Mars stories share the same universe. The earliest in my future history is “Ancilla,” in Bull Spec. Two others are set in the Asteroid Belt: “Lemonade Stand,” in the March/April 2020 Analog, and “Ghost Strike” in the November/December 2020 Analog.
