Interesting editorial over at Wired today: Go Deep! The US needs a NASA for exploring the oceans.
NASA has had its day. It’s given us technological marvels from cell phones to SETI screensavers. But we’re not mining the moon. We’re not terraforming Mars. And we’re certainly not finding any aliens. We’ve gotten completely off track: choosing to look for long-dead microbes 390 million miles away on Europa, while neglecting undiscovered life just miles off the coast of North America.
About 94 percent of life on Earth resides in the oceans. We’ve seen only about 2 percent of this vast ecosystem – the uppermost layer (home to fish, whales, scuba divers, and most known marine life). Beneath this warm lens lies a cold, dark, and life-rich realm of grand proportions. It’s home to creatures as far removed from the sun and human biology as any alien imagined by science fiction.
This is something that’s been bouncing around my brain for quite a few years now. While I certainly don’t want to see space exploration stop (and I am excited about some of the new ideas being proposed), it’s amazed me that we’re basically ignoring such a huge expanse of unexplored territory, right here on the very planet we live on. Surely some of the advances made in our exploration of space could be adapted to serve in an underwater environment, since some of the same concepts apply (such as keeping a standard pressure environment stable in an environment with a vastly different pressure — much more, rather than much less).
What new technologies could be created as we explore the new problems? Or what current technologies could be adapted and improved? We’re already seeing more and more work in hydrogen-powered automobiles — why not incorporate some miniaturized desalinization plant with a hydrogen-powered engine, and then any submersible could have a nearly infinite supply of fuel (think of a Bussard Ramscoop for a sub)? The linked Wired article mentions some of the odd chemical processes that are ocurring naturally by undewater thermal vents — who knows what kind of chemical tricks we could learn by studying these?
I just think there’s a lot to be explored in a frontier very close to home, and it’s a real shame that so little has been done in this direction as yet. Yes, I still think we need to go up — but there’s no reason we shouldn’t be going down, either.
