Humans to Mars – For and against

Today I was reading an article by Frank Stratford, CEO and founder of MarsDrive, about the benefits of going to Mars. I was nodding my head in agreement as I usually do, but after looking at the comments, one by Heinrich Monroe particularly threw me. It’s a long one, so I’ve picked out the key points (in my opinion).

Oh, we’re going to get spinoffs from it? Like “from medical technology to food and water to new materials, safety technologies, and so much more”? … You know, if we spend $100B on just about any massive technological and engineering goal, spinoffs like that… will fall out as well. The question is whether those spinoffs were really worth $100B, and whether we couldn’t have gotten more value on them with smarter investment.” – Heinrich Monroe

When I talk about the value of having space science programs, in addition to the intrinsic value of advancing scientific understanding, I often refer to the unforeseen advances in technology that come as a result. For example, we probably wouldn’t have instant global communications via satellite feed, let alone the host of material science, medical and software advances that have resulted from space programs. But the comments made by Heinrich did make me wonder whether we could have achieved these better with direct, targeted programs.

As Donald Rumsfeld has said, there are known knowns, known unknowns and and unknown unknowns. We don’t even know about some of the discoveries to be made working on space science and their implications to every day life until we make the discovery. However, one could perhaps say the same about a targeted research program. It’s certainly a tricky one to answer, although I will say this.

There is a lot of money being used for things that I disagree with ethically, and that isn’t being used for programs such as advancing medical science. By advocating for more space science funding, I’m not convinced that this would greatly cannibalise funding going towards these other programs. It’s not a choice between one or the other.

Having said that, I would be very interested to see a study that estimates the value of space science research compared to direct research in other fields. This is presumably very difficult, as it’s hard to put a number on the value of science development (would discovering life on Mars have intrinsic value?), but this shouldn’t stop people from trying. I’m sure something like this exists, but given my experience in determining the effectiveness of charities, I wouldn’t be that surprised if it didn’t. One example is the fact that for every dollar invested in NASA, there has been a $7-14 return on investment. If you are aware of any general studies of this nature, feel free to put a link in the comments below.

I may be biased – I am a space science researcher after all!
