Titan's Alien Thunder

An anonymous reader writes "What is not being reported much about the fascinating Huygens descent to the surface of Saturn's largest moon, Titan, is its remarkable microphone. In the silence of space, the probe offers a platform for listening to alien thunder while watching the lightning strike on this alien world--the only moon with an atmosphere thicker than our terrestrial one. The probe detaches from Cassini on Christmas for its atmospheric entry on 14 January 2005. The landing target on Titan borders a bright-dark region thought to be an oil-rich shoreline. Huygens can float for a few hours while still broadcasting if it lands in a lake of oil."

      Well, yes, it does. The reason why finding methane on Mars would be more exciting than methane on Titan is that on Mars, atmospheric methane is not expected to be stable, as it reacts with hydroxyl ions in the presence of sunlight to produce carbon dioxide and water (it should be noted that if the data concerning methane on Mars is right, the concentration is around 10-15 ppb, so don't expect a greenhouse effect and rain clouds any time soon). The methane on Mars would have disappeared within a few hundred years were it not replenished somehow- and the question then, is "How is methane on Mars replenished?"

      The two possibilities (and both could be correct) are outgassing from geologic processes or production by methane-producing organisms. Either possibility is actually pretty exciting, as Mars as we know it now is geologically dead- it has the largest volcano in the Solar System, but no evidence of active or recent vulcanism, but of course the possibility that colonies of methanogens similar to terrestrial Archaea are producing methane on Mars would be a much more momentous discovery.

      The methane and ethane on Titan, OTOH, has been there for billions of years and is almost certainly from nonliving processes, just as the methane in the atmospheres of the gas giant planets has nothing to do with organisms. It is interesting, still, though, because methane and ethane, gases on earth, may exist as liquid on Titan. A moon larger than Pluto and Mercury with seas of simple organic compounds (and possibly a "snow" of various hydrocarbon and nitrile compounds). A atmosphere denser than earth's composed of 94% nitrogen. Possibly large quanitities of water ice. All definitely reasons to go explore.

      Unfortunately, it is extremely unlikely that life has developed on Titan, simply because it is far too cold (about 94K). The basically opaque atmosphere and distance from the sun make really interesting chemistry very difficult, in particular, keeping any water locked up as ice rather than making it available as liquid or vapor. There may be some interesting stuff going on in the upper reaches of the atmosphere, though, as UV breaks down methane and nitrogen gas to produce a variety of polyacetylene and polynitrile compounds which fall as a waxy precipitate (the aforementioned "snow").

      The geology of Titan is essentially still a question mark, owing again to the orange-brown veil. If anything like the deep-sea vents of earth exist on Titan, they could provide the rest of the requirements for life- they'd inject heat into the ecosystem, possibly freeing up water vapor and oxygen from the ice, and could provide elements like phosphorus and sulfur (giving the sought-after CHONPS). Also, Saturn produces tremendous tidal forces on Titan. While on the one hand, the development of life on earth was helped substantially by the presence of intertidal areas (which still feature incredible diversity), the tides on Titan may so strong as to quickly erode continental features. There are a lot of mysteries that will be solved after Cassini-Huygens, and no doubt a stack of new ones will be found.

    For example the camera on the $4 billion Cassini mission is only 1 megapixel - if we had a larger number of smaller, cheaper missions, would we be there now with a much better imaging system. Cassini had a much delayed launch, so the design was outdated by the time of its launch in 1997. The same mission launched on a later window could have used ion propulsion (SEP/RTG combo) saving weight (1/2 the 4 tons Cassini weight is fuel)

    The same thing could happen with JIMO - if NASA spend $10 billion on that, they could forego many other missions, such as a New Horizons II mission, which would give us a chance to look at Uranus (not always a good word to say on Slashdot) with modern instruments, as well as Jupiter & some more KBO's..

    Also think about Hubble - is it worth spending $2 billion on a robot to repair the aging telescope, when the same money could buy better new space telescopes.. (see link above)

      I remember reading a debate among scientists about the cost of Galileo, a (now-defunct) Jupiter orbiter similar to this Saturn mission. There were some very sensative-but-expensive instruments aboard Galileo that scientists concluded likely would not make it onto a lower-budget mission.

      IIRC, one such instrument was a sensative magnetometer that detected small magnetic fields in/on one of Jupiter's moons, I think Ganamede. This suggests a there may be a liguid ocean deeper within it, or at least tidally-induced melting of some sort. Such studies may help determine the existence of and depth of such oceans. It may help guide design of future Europa missions, for example.

      One of the reasons the magnetometer was so expensive is that it had to be mounted away from the space-craft so that the craft itself did not interfere with readings. However, this required a complex "boom" that folded during launch and unfolded in space to stretch far enough away from the craft.

      Galileo and Cassini are packed solid with tons of strong scientific instruments. The newer cheaper probes tend to have less instruments or less sensative instruments.

      I agree it is less gut-wrenching to send more but smaller probes when problems due occure, but I still have not seen any good line of reasoning that the old approach is less science per dollar, only less heart-break per dollar. A Vulcan would probably argue for bigger probes, or at least that the difference is minor.

      At first I wondered if daylight would be that bright on Titan.

      "Bright" is relative. I would very roughly guess that the light that reaches the surface is a little bit brighter than as that given by a full-moon on earth. If your eyes are dark-adjusted, you would be able to see surface features in reasonable detail I assume.

      One image (Probe over Titan) shows Saturn getting light from a direction low on Titan's horizon, and yet there seems to be a bright halo around a dark cloud overhead, as if the sun were behind it.

      I am not sure which rendering you are refering to, but I did not spot anything too odd. The light-pattern in the clouds may depend on their thickness, and the thickness may be variable. Thus, the clouds may be bright in some spots and dim in others based on their blotchiness pattern alone.

      Also, their reflectivity characteristics may be different than those on Earth because they are not water-vapor clouds. Note how the sky is orangish on Mars during high-noon, but blue near a sunset, yet reverse on the earth. Things may look out-of-whack on Titan.

      One thing that does stand out as contrived is how easily Saturn is visable. The Voyager probes could not see any surface, so more likely the reverse is also true: you can't see distinct features above the clouds, such as Saturn.

      Perhaps every now and then the clouds part enough that a hazy Saturn could be seen. Or, the artist could just claim that a special filter is being used to view the scene. Cassini has just such a filter to view the surface.

      Another thing, the sky would likely be brighter than the surface, as is usually the case with amorphous (clouded) light. Except if the cloud cover is uneven, then there could be brighter spots on the ground from time-to-time as "holes" allow more light in at times.

      But any such art peices should be taken with a grain of salt. Nobody has been there before, so it is all just an educated guess.

There tend to be light areas and dark areas on some of the earlier images. Although they suspect the darker areas are hydrocarbon lakes, nobody knows for sure at this point. Cassini has a special filter to see through most of Titan's clouds. The Voyager probes, lacking such fitlers, only saw clouds and haze even though they passed fairly close. The filter makes things more exciting this time.

      What I would really like to know is if they can adjust the course of the lander if they find something new. For example, if they found a bubbling valcano at the current landing target, can they change the landing target to avoid the volcano?
