well we are getting close to the Huygens probe landing on Titan. What do people expect to be found there? Hydrocarbon seas as been suggested? life?

We know vere few about Titan, we're not able to see trough the thick atmosphere.
I'm most curiously to the surfacepictures, same as marspics :lol:
I were happy see mars panaroma pictures but I know the surface of mars already by Viking probes. Titan surface is just explored for only about 5%

Are there any links pertaining to any radar etc images of titan?

it's posted here before, i did a search but still no find, even in the post I saw a animated gif of a piece of titan's surface too.

They still unsure if there is life or not, but if they really looking for life on Titan, I bet they have looking for the organisms (cell) first ^^ e.g microbes, bacteria, and microorganisms etc...

Hope this help

What little that is known about Titan was gleaned largely from the Voyager I flyby in 1980 and some near-IR observations by Hubble. One perception of the whole system is to look at it as an oceanographic one, with tides, erosion, "fog", the whole works. Instead of water, it would be an ethane-methane sea eroding a land surface of water ice and rock. Could life form in pockets of water in the sand? Have the temps been low enough for some key reaction to have gone to completion? There are obviously carbon-bearing materials present, abiogenic in nature, but, who knows what has happened with them. There is some work being done on methanogenic life being created in and living in a non-aqueous environment, but that is obviously speculative and theoretical, at best. The organic cauldron that seems to exist on Titan has got to be something spectacular.

In our past searches for life, we have always had romantic expectations about finding life on other planets in our solar system.

As the first venera was pummeling throught the Venusian atmosphere, returning data that boggled the imagination of the decades' scientists, pressures exceeding 400 earthly atmospheres in the Venusian cloud system, sulphuric acid, metallic snow were readily observed, even on subsequent missions.

However, even though we had direct data that Venus was a veritable hellhole, the great Carl Sagan, was adamant that 'a habitable region' just might exist under all that hot dense atmospheric hell.

This is but one example, albeit a very early one, of how everytime we have sent probes to search for life, we have had great expectations, and lofty romantic ideals, but have always come up short...

The most tantalising evidence YET of life outside earth, came from a martian meteorite that scientists found in Antartica. It shows a fossilised mulitcellular organism, however, given that the martian rock was discovered on Earth, we cant be completely certain that it isnt Terrestrial life. But it is the most tantalising evidence yet...
