Space exploration has however been struggling with the global financial crisis and has too proven subject to spending cuts. In particular NASA's planetary science budget, which is seen as crucial to finding habitable planets, was slashed by $300 million this year.
(An imaginary conversation in a boardroom somewhere)
"Please, sir, I would like a few billion to explore space; one day it could help ensure the survival of the human race." "What? You're not living in the real world. Don't you know we are in an economic crisis here?"
Next chap: "Please, sir, could we have 1,000 billion
of taxpayers' dollars to go to foreign countries, kill millions of soldiers and civilians, blast their infrastructure back to the stone age, and generally leave the place in ruins?" "No need to ask, of course you can!"
There is no shortage of money or resources. If we stopped killing each other and worked together, we could have a settlement on Mars within a decade or two. It would be a good first step to further exploration of space.
