Next, buddy up with the engineers working to terraform the Martian hillsides. It’s their job to turn all that red dust into Earth-like soil that can support robust vegetation and seed the atmosphere to rain and form lakes and oceans. Figure out where future beachfront property will be, buy it, and auction off lots to the highest bidder. Of course, this prosperous career path has its risks. You’ll be outdoors a lot, and Mars’s atmosphere is pretty thin, so cosmic radiation could fry your DNA. Things could fall on you on construction sites. And you’d probably go prospecting alone (why split the profits?), so no one could help you if you got lost or fell into a crater. You could play it safe in the colony, working at the Spacemart. But you’re on Mars—take a chance! Robert Zubrin is president of the Mars Society and author of How to Live on Mars._
