Freakonomics asks – Is Space Exploration Worth the Cost?

Freakonomics has an excellent quorum of space experts and economists talking about a very interesting question – Is Space Exploration Worth The Cost? There are some interesting points made although all of the participants are in the field of space science, so naturally they all agree it’s a good thing! It would have been nice to have a few dissenting views but even so there are some good quotes here.

G. Scott Hubbard: “We explore space and create important new technologies to advance our economy. It is true that, for every dollar we spend on the space program, the U.S. economy receives about $8 of economic benefit. Space exploration can also serve as a stimulus for children to enter the fields of science and engineering.”

Keith Cowing: “Right now, all of America’s human space flight programs cost around $7 billion a year. That’s pennies per person per day. In 2006, according to the USDA, Americans spent more than $154 billion on alcohol. We spend around $10 billion a month in Iraq. And so on. Are these things more important than human spaceflight because we spend more money on them? Is space exploration less important?”

John M. Logsdon: “In the longer run, I believe that human exploration is needed to answer two questions. One is: “Are there activities in other places in the solar system of such economic value that they justify high costs in performing them?” The other is: “Can humans living away from Earth obtain at least a major portion of what they need to survive from local resources?” If the answer to both questions is “yes,” then I believe that eventually some number of people in the future will establish permanent settlements away from Earth.”

Personally I agree with Charles Stross that living away from Earth has so many things to overcome that it’s unlikely without huge discoveries but the value of space exploration in our lifetimes may be in asteroid mining – with many new technologies like solar cells rapidly using up some of Earth’s more scarce elements.

  1. Space based power production for Earth, though admittedly a macro-engineering task of huge proportions has the potential to gain the world the time needed to avert global warming without thoroughly wrecking economies and provoking wars over dwindling carbon based energy stores. That’s a potential that demands more spending to lessen the cost to orbit, learn how to live in space for long durations, and perfect robotic systems. It’s a better way to spend the money than waging a dubious war overseas that misses the entire point of eliminating terrorism and instead plays into the hands of extremists.
