Space

Is the Ocean the Real Final Frontier?

Captain Kirk and Jacques Cousteau: The ultimate battle.

|

We shall not cease from exploration
and the end of our exploring
shall be to return where we started
and know the place for the first time

That tidbit of T.S. Eliot is stolen from Graham Hawkes, a submarine designer who really, really loves the ocean. Hawkes is famous for hollering, "Your rockets are pointed in the wrong goddamn direction!" at anyone who suggests that space is the Final Frontier. The deep sea, he contends, is where we should be headed: The unexplored oceans hold mysteries more compelling, environments more challenging, and life-forms more bizarre than anything the vacuum of space has to offer. Plus, it's cheaper to go down than up. (You can watch his appealingly arrogant TED talk on the subject here.)

Is Hawkes right? Should we all be crawling back into the seas from which we came? Ocean exploration is certainly the underdog, so to speak, in the sea vs. space face-off. There's no doubt that the general public considers space the sexier realm. The occasional James Cameron joint aside, there's much more cultural celebration of space travel, exploration, and colonization than there is of equivalent underwater adventures. In a celebrity death match between Captain Kirk and Jacques Cousteau, Kirk is going to kick butt every time.

In fact, the rivalry can feel a bit lopsided—the chess club may consider the football program a competitor for funds and attention, but the jocks aren't losing much sleep over the price of pawns and cheerleaders rarely turn out for chess tournaments. But  somehow the debate rages on in dorm rooms, congressional committee rooms, and Internet chat rooms.

Damp ocean boosters often aim to borrow from the rocket-fueled glamour of space. Submersible entrepreneur Marin Beck talks a big game when he says, "We can go to Mars, but the deep ocean really is our final frontier," but he giggles when a reporter calls him the "Elon Musk of the deep sea," an allusion to the founder of the for-profit company Space X who is rumored to be the real-life model for Iron Man's Tony Stark.

Even Hawkes admits that he "grew up dreaming of aircraft"—though he means planes, not spaceships—but "then I got to look at this subsea stuff and I saw this is where aviation was all those years ago. The whole field was completely backwards, and that's why I jumped in."

While many of the technologies for space and sky are the similar, right down to the goofy suits with bubble heads—the main difference is that in space, you're looking to keep pressure inside your vehicle and underwater you're looking to keep pressure out—there's often a sense that that sea and space are competitors rather than compadres.

They needn't be, says Guillermo Söhnlein, a man who straddles both realms. Söhnlein is a serial space entrepreneur and the founder of the Space Angels Network. (Disclosure: My husband is a member.) The network funds startups aimed for the stars, but his most recent venture is Blue Marble Exploration, which organizes expeditions in manned submersibles to exotic underwater locales. (Further disclosure: I have made a very small investment in Blue Marble, but am fiscally neutral in the sea vs. space fight, since I have a similar amount riding on a space company: Planetary Resources.)

As usual, the fight probably comes down to money. The typical American believes that NASA is eating up a significant portion of the federal budget (one 2007 poll found that respondents pinned that figure at one-quarter of the federal budget), but the space agency is actually nibbling at a Jenny Craig–sized portion of the pie. At about $17 billion, government-funded space exploration accounts for about 0.5 percent of the federal budget. The National Oceanic and Atmospheric Administration—NASA's soggy counterpart—gets much less, a bit more than $5 billion for a portfolio that, as the name suggests, is more diverse.

But the way Söhnlein tells the story, this zero-sum mindset is the result of a relatively recent historical quirk: For most of the history of human exploration, private funding was the order of the day. Even some of the most famous examples of state-backed exploration—Christopher Columbus' long petitioning of Ferdinand and Isabella of Spain, for instance, or Sir Edmund Hillary's quest to climb to the top of Everest—were actually funded primarily by private investors or nonprofits.

But that changed with the Cold War, when the race to the moon was fueled by government money and gushers of defense spending wound up channeled into submarine development and other oceangoing tech.

"That does lead to an either/or mentality. That federal money is taxpayer money which has to be accounted for, and it is a finite pool that you have to draw from against competing needs, against health care, science, welfare," says Söhnlein. "In the last 10 to 15 years, we are seeing a renaissance of private finding of exploration ventures. On the space side we call it New Space, on the ocean side we have similar ventures." And the austerity of the current moment doesn't hurt. "The private sector is stepping up as public falls down. We're really returning to the way it always was."

And when it's private dough, the whole thing stops being a competition. Instead, it depends on what individuals with deep pockets are pumped about—or what makes for a good sell on a crowdfunding site like Kickstarter.

Looking for alien life forms? You probably think you're a natural space nerd, but you're wrong. If the eternal popularity of "Is There Life on Mars?" stories is any indication, an awful lot of people are just hoping for some company. We really have no idea what's hanging out at the bottom of the Mariana Trench, but there are solid reasons to think the prospects for biological novelty (and perhaps even companionship for humanity) are better down there than they are in Mars' Valles Marineris.

Want a fallback plan for when that final environmental catastrophe occurs? Underwater or floating habitats may offer fewer challenges than space colonies if you're looking to quickly build a self-sustaining place to live when things cool down, warm up, dry out, or otherwise lose their fitness for human habitation.

If you're just looking for wide open spaces, the vastness of space may ultimately prove your final frontier, but Söhnlein has a very human take on the question: "For myself," he says, "I'd probably go with the oceans. Humanity has millennia to explore the cosmos. But I have only decades or—depending on who you believe—centuries. And there's plenty to discover down there to fill my lifetime."

  1. Did you even watch seaQuest DSV? No, of course you didn’t. Nobody did, because the ocean is boring.

    1. I watched it! *whispers* Once.

    2. Um, I grew up watching that show?

    3. Was that the one with Roy?

      1. I think he got replaced by someone else after he realized he was in it.

    4. I didn’t watch SeaQuest but I saw a old tv series similar about deep oceans and also threats coming from some undersea civilisations named Stingray http://www.youtube.com/watch?v=E06cNv55jTs produced by the late producer Gerry Anderson well known for Fireball XL5, Thunderbirds, Captain Scarlet, UFO and Space 1999.

    5. No, but I watched Sealab 2020, which was cool, and now only 7 years away from fruition.

  2. Not in the ocean! Inside the ocean! In the heaviest, deepest, most brutal part – THE MARIANAS TRENNNNNNNNNNNNCH.

  3. here’s no doubt that the general public considers space the sexier realm. The occasional James Cameron joint aside, there’s much more cultural celebration of space travel, exploration, and colonization than there is of equivalent underwater adventures

    There’s always something sexy about going somewhere else. Exploring the sea is a bit like figuring out what’s at the bottom of your dark closet. It’s a space that’s in your house, you just don’t go there because it’s a pain in the ass. Which brings me to my second point:

    People sometimes don’t realize that going into space is, in some respects, easier than it is to go to the bottom of the ocean. Or maybe I could say, to BE IN space in easier. Going there is tough, sure, but once you’re there, you can float around in a tin-foil capsule with a leaky space suit and you’re fine.

    Deep oceans? Not so much. The difference between 14lb per sqin and zero isn’t that much. But the difference between 14lb per sq in and… a zillion lbs per sq in is huge. The stuff required to survive at the ocean bottom is very difficult to build, survive and move around in.

    1. On the flip side, you don’t burn up on reentry from underwater, and there’s abundant food and water.

      1. No, something even worse happens coming up too fast.

        1. Not in a pressurized vessel, so far as I am aware.

      2. “Water, water, every where,
        And all the boards did shrink;
        Water, water, every where,
        Nor any drop to drink.”

  4. Seasteading would be much easier than colonizing space, but the downside is you are still within reach of the world’s government navies. In space, it costs a lot more to go after you once you declare your independence.

    1. Eventually that may be the case, I think the first colonies in space will be heavily indoctrinated/monitored to prevent any mishaps due to little things like murder and sabotage.

    2. Well the ‘verse is a big place, so you can always run from the Alliance. As long as I have a bona fide companion I’ll be OK. If you got a job to do, I can do it, don’t much care what it is.

  5. The ocean can be subdivided with three dimensional (four dimensional?) property boundaries and title restrictions, just like we do with land. It should be easier than ever now with technologies like GPS. Someone can own an area of the water surface and volume of water to a certain depth below it for fishing, while somebody else could own the floor directly below that for mineral extraction.

    1. The problem today being that corporate interests would snap up anything worth more than sand because they have the wealth and equipment (to detect resources) to do so.

    2. Um… that’s sort of a terrible idea.

  6. The problem is that deep sea exploration is relatively easy, deep sea exploitation is hard as hell, MUCH harder than exploiting the earth – moon system or mining asteroids.

    The technological hurdles in building an iron mine that operates 5 miles below the surface dwarf the technological hurdles that would need to be overcome to place a space habitat at the Earth-Moon L5 point then go capture a nickle iron asteroid and tow it there. The cost for the space mine would be cheaper as well.

    1. Really? We already drill for oil miles beneath the surface. I admit, that’s not the same as an iron mine but the cost for the rockets, mining equipment, life support equipment, etc., to get to the moon will be astronomical…. no pun intended.

      1. Yes, really.

        Getting into space is more expensive than going down to the bottom of the ocean but we’re not just talking about getting there, we’re talking about robotic systems and manned habitats operating there continuously for years at a time and that is something that is MUCH simpler to do in a vaccuum than it is to do in a highly corrosive high pressure water environment

      2. Also even with the deep water oil drills, the only thing going down to the bottom of the ocean is the drill tip, the drilling platform hangs around on the surface of the ocean

  7. Jackie Frap jumped over the candle stick he did!

  8. “In a celebrity death match between Captain Kirk and Jacques Cousteau, Kirk is going to kick butt every time.”

    One saved the Humpbacks, the other blew up dolphins with dynamite for shits and giggles.

    Close one.

  9. Thanks for informative share!

  10. . . .That federal money is taxpayer money which has to be accounted for, and it is a finite pool that you have to draw from against competing needs, . . .

    Accounted for? Finite pool? When did that start?

  11. Space is the final frontier, underwater may be the next frontier however.

  12. Well, let’s just hope we are not screwing up that “final frontier.”

  13. Space is more exciting to most people because it holds the theoretical potential for expansion. There is no possible way people could ever live in the deep sea, so most people see no value in it.

    1. Agreed. Spend as much money, do as much research and development as you want, you will never find a place under the ocean where the water pressure suddenly decreases and you have habitable space where you could form a sustainable colony. With space travel, there’s always the possibility that, somewhere, there’s an Earth-like planet we could live on with minimal alteration. And even if there isn’t, the difficulty in terraforming a planet that’s at least reasonably suitable (Mars comes to mind, and I believe there’s a moon of Saturn that’s supposedly pretty close to liveable) for human colonization is much, much less than doing the same on Earth in the deep sea.

  14. Finally, I can find out the information that I am looking for. Thanks!

  15. I’m particularly amazed with how well you actually explored this material. I personally believe this is sound info and I also agree.
