As I already said, I'm not in favor of the government auto industry bail out. The problems GM has are chronic. It will burn through the billions of dollars it just got from the tax payers in a just a few more months. GM will then go back to our government with its begging bowl. It was among the walking dead long before the subprime crisis, and it won't be restored to health when the subprime crisis ends. Our politicians are excellent at making malinvestment with other people's money.
I don't object to my tax dollars being spent on genuine good scientific research, including molecular biology, advanced solar cells, fusion, or even sending cheap robot explorers to Mars. But sending people to Mars is every bit as foolish as bailing out GM. What we will learn is that it's bloody hard to send a man to Mars and keep him alive there, which we already know.
We managed to find $25 billion to fund bailing out a moribund auto industry. It seems to me putting that money into a forward-looking industry rather than a backwards-looking one would have been a much more worthwhile use of the money.
A common logical fallacy -- "We wasted $x on A, so it's okay to waste $y < $x on B.". I am not in favor of the government bail outs. So far as I'm concerned GM should just spin off Corvette to Honda (the only GM car people actually dream about owning) and let the rest of the company die. But at least people actually get some utility out of cars -- they drive them every day. Nobody drives to the moon and we already know what's there -- a big dead rock. The actual scientific work is done far more cheaply with unmanned probes.
By the way, "we" didn't find $25 billion for the car company bailout. Every cent of every bail out is being borrowed.
How is sending people to the moon or Mars a worthwhile activity? Sci fi fantasies about settling Mars and what not are just ridiculous. Antarctica is infinitely more hospitable to human settlement than any other planet or moon in the solar system, yet nobody considers it sensible to build cities in Antarctica. As for technological spin offs, it would be far more efficient to invest the money directly in developing the spin offs rather than waste 90% of it going to Mars.
