I am attaching some excerpts so others can better tell if a visit might be worth the trouble.

Saturn moon [Tethys] once had an ocean: One of Saturn's moons may once have harboured a liquid ocean beneath its icy surface, scientists have told a major conference in Houston, Texas. [2008 March 14]
[...]
They propose that Tethys' orbit around Saturn was once perturbed by gravitational interactions with another moon - Dione - which made Tethys' orbit more "eccentric".

The resulting tidal forces caused frictional heating of Tethys' interior.

But at some point, the orbital interaction between Tethys and Dione was broken, and Tethys fell back into a less eccentric orbit. As it did so, it began to cool.
At least one was new news.

Saturn is so far above us in the Sun's gravity well, that I really don't give this idea much weight. (No pun intended.) Not to mention that those germs would have to survive in space long enough to reach Titan, and then survive on Titan.

It sure would, and welcome to BAUT, by the way.

Huh? If you're talking about space habitats, then I kind of agree; it'll at least give us the option of getting away from those who trouble us. But "no struggle"? That's just not consistent with the species I grew up in.

Lichens survive 15 days unprotected in space

Bacteria recovered from Moon surveyor 3 may have survived 31 months on the moon

Or, much more likely there was no live Streptococcus mitis on Surveyor 3.

Wikipedia: Reports of Streptococcus mitis on the moon

Quote:
Streptococcus mitis lives in the mouth; there is no evidence that it can survive for long even in terrestrial environments outside the human body.
[...]
One of the implements being used to scrape samples off the Surveyor parts was laid down on a non-sterile laboratory bench, and then was used to collect surface samples for culturing.
[...]
On the above evidence, the most parsimonious explanation for the reported recovery of Streptococcus mitis from the Surveyor 3 camera is contamination after its recovery from the Moon. Survival of this bacterium on the surface of the Moon would be very unlikely. This claim has never been documented in any peer-reviewed scientific publication and remains a telling example of the phenomenon of urban myth.
The lunar bacteria don't impress me, but I think we've found a legend that cannot be killed.

A tiny fraction of the millions-year journeys a meteor usually needs to pass between planets.

True, but the fact is, bacteria can spore up and go into sleep mode almost indefinitely.

250-million-year-old bacteria revived in a laboratory

Wow, pretty impressive! Does it say what methods were used to revive it? I'd be very interested to know if those conditions can exist in nature. And of course, if a stomach-dwelling bacterium could survive the ocnditions on another planet.
