Titan issues

Okay, getting all "xeno" for a moment, what would it take to have "life" on
Titan? Mean surface temperature is around -178 degrees C, at about 1.5
Earth atmospheres pressure. There would need to be something like enzymatic
activity based on the available carbon chemistry, which we don't know much
about. There's nothing like that on Earth, but there doesn't need to be.
This would have to sustain some kind of organic heat engine to power
whatever the
putative organism was, but it should only need a differential of
temperatures for that. Then it's only a small step to
sludge-farming Amazons who have never seen stars.

Setting that aside as perhaps far-fetched, there are obviously unique
organic chemical processes in the Titan environment. How much thought has
been given to the possible impact of the Huygens probe on these processes?
What is the surface temperature of the probe after atmospheric
ntry? ---And the probe will be carrying some of the unique carbon chemistry
of Earth. Could it possibly be boiling away or otherwise contaminating the
chemical processes that make Titan interesting to us?
