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."
It would be real great if they did find some primitive life there. But then the next mission all of it was whiped out by Small Pox, or some other virus that is compleatly forgen to the moon. Learn from the Simpsons, Rember what the Bull Frogs did to Austrailia.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
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.

No, no and no.
Radio/radar have nothing to do with it. Nor does a "still hot core." Any body the size of Europa would have cooled by now, even with radiactive heat. (Mars, being much larger, is also largely cooled.)
We are pretty sure that there is a liquid ocean because 1) The pattern of cracks imaged on the surface. 2) The types of surface features, which are generally held to be consistent with a liquid ocean under the ice. And 3) the Galileo magnetometer measurements of an induced magnetic field, indicating a lquid interior. Modelling indicates that the field is only consistent with a liquid near the surface, not the in the core.
The heat needed to keep the water liquid comes from tidal flexing due to the forced eccentricity of Europa's orbit, unlike the usual situation for rocky bodies
His response: "The technology we've developed due to NASA projects is huge, and mostly unmeasurable. For example, the VCR your parents own would not be possible without technology we developed in our quest to explore outer space."
This is sad. Today the tables have turned.
We wouldn't be able to explore the moons of Jupitor if it wasn't for the technology we developed to make some sappy chick-flick.
Our thirst for entertainment has become paramount, and all else is now secondary!
