Personally I don't think we should be going to Mars. It's too far away, it's expensive, and we've still not been able to explore the absolute depths of
our own oceans. I'm sure there's some scientific reason for one day going to the red planet but personally I just want the boffins to find me some freaky shit to stare at. Have you seen some of those crazy fucking fish that are living in the deeper parts of the oceans? They're amazing. They're all crazy colours with massive teeth and tentacle-like dicks on their heads. I mean just look at the giant squid- what the hell is it?! It looks like some sort of biological, satanic sex toy! Even if we do find some sign of life on Mars, it's not going to be as impressive as that. And if it is then I'm pretty sure we run the risk of it being sentient enough to be into the whole anal-probe thing. I don't know about you... but when given the choice of either finding some massive fucking Kraken or having an alien ram its equipment up my arsehole I know which one I prefer.
