Kim Stanley Robinson writes bestselling novels about a colony on Mars. Elon Musk talks of actually colonizing Mars. There is even a 30-page constitution, courtesy of a Yale political science class, for a Mars settlement.

The Yale proposal is about how to make a Mars settlement democratic, as is an earlier proposal published in Space Legal Issues. But I fear a harsher question needs to be addressed first: Should a Mars settlement allow for contractual servitude?
