You may want to tune into another episode from The Planetary Society’s podcast Planetary Radio is you are pondering space settlements on the Moon and Mars. The recent program, A City on Mars, is a discussion with authors Kelly and Zach Weinersmith who wrote “A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through?“
The bottom line is that we should not rush towards permanent settlements at either location until we know more about the human body, the human mind, and human politics (good luck with the last one).
The conversation covers a variety of risks, including the effects of gravity on the human body, the ability to procreate in space, and the effectiveness of treaties as nations plan to settle and mine the Moon and Mars. The authors note that we have not had ample time to study all of these issues even with the International Space Station (ISS) in orbit because this has not been the focus of many space efforts to date. For instance, the ISS does not test the impact of radiation on humans because it is in low Earth orbit within the protection of the planet’s magnetic field.
Overall, the authors advise time and more study before jumping into a settlement. This may mean putting off permanent settlements for a few hundred years.
And what about Elon Musk’s plan to start shipping colonists to Mars in his lifetime? As with many things related to Mr. Musk, he does oversell ideas. His energy in the infrastructure realm is good, but his predictions related to humanity in general are usually unreliable.
