Twin Robots Scope Out Titanic, Europa Next?
jmichaelg writes "Wired is running an article on a pair of submersible robots that work in tandem to film underwater scenes. One robot illuminates a scene by placing the light source as close as possible to the object being filmed while the other bot manuevers for the best camera angle. That, and a host of other innovations, makes the pair significantly different than the equipment used when the Titanic was originally filmed. Significant enough that JPL has expressed an interest in using the technology to swim in Europa's seas. How JPL will overcome the time delay isn't mentioned but it's an interesting read nonetheless."
In the late '90s, scientists discovered the Titanic was being consumed by a new life form, composed of 20 different species of bacteria, two species of fungus and two species of Archaea that, together, form a symbiotic rust coral or rusticle (they look like icicles) that thrive on iron.
These rusticles have formed a single biological mass that is believed to be the largest life form on earth. It seems like poetic justice that this death site of historic magnitude should make such large contributions to man's discovery of new life, not only on Earth, but perhaps on other planets as well.
Interesting, I have never heard of this before, does it really count as a single lifeform ?, sounds like a micro ecosystem to me.
Cool. Not to make everyone else too jealous, but I was recently at a presentation by Mike and Jim Cameron about this project. Mike gave about a short presentation about the development of the ROV, and then Jim gave a much longer one about the missions. How cool is it that one of the project paramaters is that the ROV has to be small enough to fit in a "B" deck window? One of the many great quotes of the evening from Jim was "I paid for these guys, so I drove mine on every dive. Mike had to share."
The footage is *AMAZING*. There are stained glass windows completely intact. In one stateroom, there's a water pitcher sitting on a shelf above a water glass still standing upright on a vanity. Still upright!!! After the sinking and the impact! Jim talked about how important it was to have 2 units, so that there could be "characters" in the shots. Oh, and not to ruin anything, but Bill Paxton is in on the project. The quote went something like "I'm making Bill do for real what he pretended to do in the movie"
At one point they had a battery failure on one of the units due to a manufacturer's defect. So they rigged up a harpoon to the other, and went in and rescued it. It was an amazing feat, and they surfaced absolutely elated. But their victory was short lived, for the date of the rescue was 11 September.
At several points during the presentation the audience broke into applause at the sheer grandeur of the footage. I can't wait to see the finished project, especially after they get some of the stuff enhanced and cleaned up. There were 12 dives on Titanic, 9 of them filming missions. And trust me on this one guys, you *must* see this film. Even if you aren't into wrecks, it will blow your mind.

I'm more interested in how they're going to get two submersible robots under a few kilometers of ice first. Not to mention, to communicate, they'd have to be tethered (water isn't real conducive to radio communications). They've got a lot more than just a time delay to worry about.
I don't see how this could be reliably automated. Maybe with some people drilling it could be done, but I have a feeling that if we dropped a robotic drilling system, something would go wrong. It's just a bit too complex for me to have faith in it.
"instead of dragging the cable into the hull and returning on the exact same path (and perhaps catching the optical fiber on something), the bots continually feed out the cable they need and exit the wreck wherever it is convenient.
When the bots get back to their docks on the submersibles, the umbilical is simply jettisoned. Not having to go back or untangle the cable is a tremendous time-saver. Furthermore, the cable is designed to decompose quickly so it won't leave an unsightly web-like mess for future visitors to encounter."
i wonder if decomposing fiber optic lines are good for preservation of the ship.. or the life around it..
