    This looks like drainage channels flowing to a shoreline. Perhaps the shoreline of a liquid methane sea. This world is very alien. Yet scientists say the organic chemistry on Titan may be similar (except for the very cold temperature) to the processes that occured on Earth more than 4 billion years ago. Some speculate that if "pre-biotic" chemistry is occurring on the cold temperature surface, then perhaps in the warmer Titan interior such chemistry is further advanced. How far? You speculate. Thirty years ago, no one guessed that non-photosynthetic life would exist around volcanic vents deep in the ocean near the Mid-Atlantic Ridge.

    This image was returned yesterday, 14 January 2005, by ESA's Huygens probe during its successful descent to land on Titan. This is the coloured view, following processing to add reflection spectra data, gives a better indication of the actual colour of the surface. Initially thought to be rocks or ice blocks, they are more pebble-sized. The two rock-like objects just below the middle of the image are about 15 centimetres (left) and 4 centimetres (centre) across respectively, at a distance of about 85 centimetres from Huygens. The surface is darker than originally expected, consisting of a mixture of water and hydrocarbon ice. There is also evidence of erosion at the base of these objects, indicating possible fluvial activity.

    Aren't these just so excellent? What wonderful and terrible times we are living in. Perhaps it's always been so?

    I think that through the ages humans have often had the perception of "wonderful and terrible" times. What changes is the rate of change from one wonderful and terrible time to the next. About 500 years transpired between Leif Erickson and Christopher Columbus. Only one year elapsed between robots on Mars and touchdown on Titan. It is often observed that there are more scientists alive today than have lived in the history of the world. The rate of change will continue to accelerate.

    Agreed. The ability to build on ALL the things that have gone before. . .

    The terrible often lead to the wonderful-wars demand new tech.

    Four or five of an alleged 350 photos have been released. Where are the rest? When NASA delivered the robots to Mars, many tens of photos were almost instantly available. When Cassini reached the vicinity of Saturn, dozens of photos were posted by JPL and NASA. Where are the Titan photos, ESA? We know that half of the planned 700 hi-res photos have been lost due to an ESA software command error sent to Cassini that shutdown one of the two Huygens radio channels.

    Interesting link regarding the attempt by Hawaii's Keck Telescope (world's largest optical telescope - eclipsing Mt. Palomar near Los Angeles) to image the descent of Huygens through the atmosphere of Titan; includes an amazing photo of the Saturn moon: http://www.physorg.com/news2704.html
