If you're tired of the Mars rants, just skip to the Rocket Man cover







This Neil Degrasse Tyson segment from the Tonight Show was amusing – – both he and Stephen Colbert are good at this sort of thing and play well off of each other – – but I'm including it because it hits on a point that I've alluded to in previous conversations of space exploration and the vanity aerospace industry.

Much, arguably most, of the 21st century discussion of man's expansion into and utilization of outer space is based on an implicit and often explicit colonial era framework. This includes such respectable news organizations as the New York Times, NPR, the BBC, and most recently and egregiously the Atlantic.

Any time you see the term "Mars colony," you know you are in trouble. Almost inevitably what follows will assume that the second half of the 21st century will basically just be a remake of the 17th and 18th, despite causes and conditions being all but completely non-analogous. I have neither the time nor the knowledge to go into detail here, but if you will forgive the oversimplification, the original system was based on habitable, arable lands which generally offered significant potential for trade and were easily accessed and conquered and which required a great deal of labor in order to pay off for the colonizing power.

None of this applies to Mars or any other body in the solar system. Outside of certain research questions, there are for the foreseeable future very few economically sound arguments for a human presence in space. Even if something like Martian mining proves viable, any work on the surface of the planet will be done largely, perhaps entirely, by autonomous and semiautonomous robots. This is true now and it will certainly be more true with the AI and robotics of 2050. Based on purely practical considerations, there will be no way to justify more than the most minimal of human presences on the red planet.

This leaves us with various romantic arguments about man's need to reach out to strange lands. [Insert super cut of inspirational Star Trek speeches here.] 100 or so years ago, you might have been able to make a reasonably convincing argument for the explore and settle model. Multiple high profile polar expeditions dominated the news while scientist were for the first time probing the depths of the ocean with dredges and other specialized instruments. The idea of cities in previously inhospitable or even impossible places captured the public imagination.

But this is not 1918. This is 2018 and, as Neil Degrasse Tyson points out, no one is lining up to colonize Antarctica, nor do we have undersea settlements or subterranean metropolises. Hell, we have trouble getting people to move to North Dakota.
