It's too bad that probe can't eject something
To cause ripples in what sure looks like liquid
then image it. -Rich |

I am sure that will all of the excitement over the probe, that a follow
up mission will be approved. Collaboration between the USA and Europe was a great success for this misssion. It was good for NASA as the collaboration made the project bulletproof from the bean counters in Washington. One idea is to lower a rover from a blimp. Titan is proving to be the most exciting world to explore outside of the earth. A second world in out solar system with liquid oceans at the surface.

Would be a tough mission - would probably require an orbiter and a
lander - can't imagine that a lander alone would be powerful enough to directly relay data to earth. Cassini captured data only until it was over the horizon from the lander's viewpoint. |

Direct communications such as is just barely possible with the Mars Exploration Rovers is out of the question for Saturn. Unless the thing was a giant dish antenna on wheels. Plus, how are your going to power the transmitter? Solar power is out for Titan. Nuclear power would be heavy and would have all the kooks protesting at the launch. Batteries aren't going to power a transmitter at Saturn for long. Bryan |

I have no idea of the physical dynamics of liquified methane, I don't even know if it behaves like water because the only sub-freezing liquids I've seen are exposed to our tempertures and react violently. But, the look of the photographs, the darkening of the small rocks/ice below the large ones seems to indicate they are immersed in something. Is it possible that the "liquid" is frozen slightly on top (like a lake in early winter) and that the sub-frozen surface "liquid" is of a consistency greater than that of water, like a "slushy" state? -Rich |

NASA says it landed on something withthe consistency of packed snow

Cassini captured data only until it was over the horizon from the lander's viewpoint. Sounds like a job for the second nuclear-powered Prometheus mission after the first one is sent to Jupiter. I can only guess how many eco-anarchists will try to kill that mission though. It also possible that Cassini, with it's RTGs and reaction wheel control system, may survive long enough to act as relay for another Titan lander (preferably a balloon probe since the thick atmosphere and haze makes detailed orbital study of the surface at 1 kilometer per pixel resolution difficult...there appear to be a lot of channels down there that I think a rover would have trouble getting across). -Drew |

They should test to see if the atmosphere is methane by lighting a
match. |
