Proposed NASA Mission Would Sail the Seas of Titan
The BBC has a report on a proposal that will be submitted to NASA for funding — a mission to Saturn's moon Titan that would deposit a lander on its hydrocarbon sea. (We recently discussed the widely-circulated photo of sunlight glinting off one of Titan's seas.) "The scientific team behind the idea is targeting Ligeia Mare, a vast body of liquid methane sited in the high north of Saturn's largest moon. ... 'It is something that would really capture the imagination,' said Dr Ellen Stofan, from Proxemy Research, who leads the study team. 'The story of human exploration on Earth has been one of navigation and seafaring, and the idea that we could explore for the first time an extraterrestrial sea I think would be mind-blowing for most people,' she told BBC News. ... The Titan Mare Explorer (TiME) has already been under study for about two years. It is envisaged as a relatively low-cost endeavor — in the low $400m range. It could launch in January 2016, and make some flybys of Earth and Jupiter to pick up the gravitational energy it would need to head straight at the Saturnian moon for a splash down in June 2023."

Oh come on, everyone knows that once you invent satellites the whole map is revealed!
If God forks the Universe every time you roll a die, he'd better have a damned good memory.
At least it could find a few sirens.
Interestingly enough, the Cassini Orbiter's landing probe, the Huygens, which landed on Titan a few years back, was designed with floatation devices, just in case it hit liquid instead land (ultimately it hit land). An interesting fact about Titan: the high density of the atmosphere, combined with a much lower gravitational force than that of earth results in very soft probe landings. In fact, it is hypothesized that on Titan, a human could strap fake wings on his arms and fly -- now if only we breathed methane and could survive at temperatures colder than -200F...
That "boat ride" is about .01% of the federal budget or what we spent on Iraq in less than 10 hours.
Sigs are too short to say anything truly profound so read the above post instead.
This sort of BS analysis has been around forever. What do you think it going to happen with the $400 million? Think we are going to launch it into space? That goes to creating jobs, and the various space programs are *a lot* more effective than the close to $2 *trillion* spent on the other bogus stimulus plans in actual job creation. Even Governor Moonbeam himself has recognized the value of the space program in economic terms.
Now, if all we were going to do was pay someone to tell us what Titan is like, certainly the information would not be worth it. Pure science has never been and will never be the purpose of NASA. But building things to find out (and this creating movement in the economy and jobs) pays off.

What exactly are your prerequisites for a manned mission then?
My concerns here about manned exploration are twofold:
One, unless we're going to build a real, permanent base on the moon, and actually keep men there for extended periods of time, then we shouldn't be going back to the moon right now. It'd be a waste, and nothing more than reliving old glories without breaching new frontiers. And with declining budgets, if we actually did go back to the moon, we wouldn't stay. Again, it would essentialy be doing it just to say that we still could. A waste. So the first argument is about needless waste of funds.
Two, as far as the other oft-proposed trip... to Mars... we shouldn't do it because of cost, but mostly, because the technology just isn't there. Specifically, we're lacking a way to keep astronauts fed and healthy for the very long trip. Suspended animation is still science fiction at this point, so unless a true breakthrough in space travel speed is found, we currently have no way to send a bunch of men on a months-long journey to another planet and back, at least not in a manner that we can afford.
The asteroid mission right now is the only place we can actually land a man involving fairly short distances, and with the virtue of it being real exploration, literally where no man has gone before.
Life is hard, and the world is cruel
I wouldn't mind paying my taxes toward space missions like this; it's all the other frivilous crap like bailouts, corporate welfare, corn subsidies and unnecessary wars that are really disgusting uses of tax dollars.
