This chapter discusses the challenges and harsh conditions of space settlement, whether on the moon or Mars. It explores factors such as extreme temperatures, radiation exposure, lack of infrastructure, and resource scarcity. The speakers also highlight the need to create self-sufficient environments to support human life in space.
Loss of taste for most foods, vision problems, loss of muscle mass and bone density. In light of these and the many unpleasant our outright dangerous effects of space travel on human physiology, science writer and cartoonist Zach Weinersmith wonders: When it comes to the dream of space expansion, what exactly do we hope to gain? Listen as he and EconTalk's Russ Roberts discuss his new book (co-authored with Kelly Weinersmith) A City on Mars, which offers a hard-nosed yet humorous look at the sobering and lesser-discussed challenges involved in building space settlements. Topics include the particular problems posed by the moon and Mars's atmospheres; the potential difficulty of reproducing in zero gravity; and the dangerous tendency to overlook a key factor in whether space settlement is a good idea: the fact that people are people, wherever they may be.
