Navigating the seas of Titan in a boat

NASA landed a rover on Mars. So what’s the next step? Right: land a boat on Titan!
Hey, come on, it’s gotta be the ultimate travel destiny:
- A magical moon that’s actually more like a planet.
- One of the most Earth-like bodies in the Solar System.
- Has an atmosphere (OK, mostly nitrogen — so bring your own oxygen, stop kvetching).
- A vast network of seas, lakes and rivers.
The perfect getaway. Quick, somebody get Richard Branson on the horn!
Just ask the scientists who ran the Cassini-Huygens mission, which studied Titan extensively in the 2000s. It confirmed that lakes, seas and mysterious rivers of liquid hydrocarbons exist, covering much of its northern hemisphere.
Now European explorers want to launch the Titan Lake In-situ Sampling Propelled Explorer (TALISE) — a quasi-mythical amphibious boat propelled by wheels, paddles or screws. (Engineers are presenting their proposals at the European Planetary Science Congress in Madrid on September 27.)
It would land in the middle of Ligeia Mare (the biggest lake, near Titan’s north pole), then boldly set sail for the coast, taking scientific measurements along the way, and presumably make some side trips to check out local attractions.
OK, Titan’s environment is too cold for life as we know it, but hey, its environment is rich in the building blocks of life, including organic compounds and well, ah, hydrogen cyanide (OK, that’s a problem, but never mind all that), which may have played a role in the emergence of life on Earth, so that’s a good thing, right?

Superb write-up, I’ve saved as a favorite this web site so ideally I’ll discover much more on this subject in the future!

Carbon nanotubes are already available for making vehicles. As chance may have it, the only vehicle reinforced by CNTs to date (at least that I am aware of) is an unmanned surface vehicle, precisely what is needed for the mission.

Well, they have found bacteria that can live in the arsenic-rich waters of Mono Lake in California, and they have found algae living beneath the ice in Antarctica, and there are bacteria here on Earth that digest oil spills…so there just could be something that can survive the cold in a hydrocarbon sea. It doesn’t seem too likely, but in an infinite universe, everything happens eventually.
But Titan is way out in the dark, so this boat would need a little nuclear generator if it were sent out using today’s technology.
But this mission probably won’t be sent out until way after 2025. By then quantum computers will be old hat (see the article elsewhere on this newsletter):
“Should we ever build quantum computers — which would be smaller and exponentially more powerful than modern computers…”
With so much more computing power, you could build a robot sailboat that could raise and lower its own sails and handle itself as if it had a crew of little sailors. Titan is known to have an atmosphere, and as it circles Saturn it will have a night and day, so it should have convective winds.
There is an entry at Wikipedia entitled, “Atmosphere of Titan,” which says that Titan is a “Super-rotator,” meaning that the atmosphere moves around faster than the surface. It also says that a the atmosphere is so thick that in the light gravity of this moon a human could fly by flapping large wings. Does this remind you of the orinthopters of “Dune?”
This means that an extended flight deck could stick out of the poop deck allowing little electric helicopters to lift off and take measurements.
The sea of Titan is much less dense than water, so the sailboat would need to be very light. By 2025 we just might be able to weave its hull and decks from carbon nanotubes (much stronger and lighter than steel). It could as buoyant as a Styrofoam boogie board.

What do you mean? No blue meanies! Where do you think they went? Argentina??? Beside, they are cold little buggers. Dontcha remember that everybody turned blue after being bonked?

Hey, I put this in there for you, Bri. Dunno, I was passed out, remember?

I hope you were drinking red wine. It’s good for your heart.

No, blue. I’m a meanie.

Before you wrote this post, I showed it to my mother, and said it was in relation to my earlier post. She loved it.
