Well, I’ve done it. Making good on a promise I made to myself while presenting a poster at the Society of American Archaeology conference in 2008, I recently submitted an article to the journal Space Policy outlining a framework for a science that doesn’t quite exist yet: Xenoarchaeology.
“Xeno” is Greek/Latin for “foreign” or “stranger.”
Seriously. I drew from SETI protocols, interplanetary geological sample return guidelines, archaeology fundamentals, and historical examples to make a call for a proactive set of xenoarchaeological guidelines. My argument? -The moment that we find something we think might be the real deal on another planet is the wrong moment to try and figure out how to study it correctly and credibly. And we’ve got spacecraft and landers everywhere these days. -It’s only a matter of time until we do cross over something that makes us double-take.
To paraphrase my general points in the paper, an archeological mindset is particularly well-suited to analyzing a site of truly unknown character, but there are planetary science landmines a regular archaeologist would be completely unprepared to dodge. Gravity, temperature, chemistry, and electromagnetic environment can all be (and likely are) very different on another world, which will affect essentially every property of an object. On Earth we can take all of those things for granted – the strength and effectiveness of friction, for example. On Mars? We had to completely redesign the drill bits used on our Mars rovers simply because the effectiveness of a cutting edge on Mars is only half what it is here on Earth because the atmospheric pressure is so low, which is in turn because the gravity is 1/3 weaker. See what I mean?
If it walks like an arrowhead, and it talks like an arrowhead… it might not actually be an arrowhead on Mars.
So, that’s my stab at taking a scientific discipline out of the realm of science fiction and elevating it to reality. -The paper made it favorably through editorial review, and I am waiting to hear back on comments from the peer referees.
My ulterior motive? I really do believe it’s only a matter of time until we find something – and if I center myself in the burgeoning discipline, when we do find something (if I don’t happen to be the one who stumbles across it, myself)… they’ll have to call me.
