>We don't know how to make real dirt on mars Bones, waste, excrements, and waste products. Buried and flipped. Maybe some bacteria. That isn't the issue. The issue will be how many years it will take to get the unfertile mars land into something fertile, and how good that dirt will be for growing stuff.

The other pitfall is that we are growing a new microbiological sphere. Which means we can fuck it up really really bad, meaning that the bacteria isn't good for human life.

So, how many humans do we have to send to Mars before there is a pile of corpses large enough to fertilize one hectare of potatoes?

Very shortly, the general views that many people hold about privacy, such as 'I don't want the world to see my sex video' or 'Those pictures of me passed out on the toilet are mortifying' or 'I didn't mean to ramble on about your privates on Twitter' will seem Victorian by comparison to what people will simply accept as part of being human. Instead of going through the draconian methods that would be required to maintain privacy, society will simple learn to accept a world without it.

That's nice. And what will you do once you get there? Play some awesome networked FPS games?

I would like to build a Moon base with 2 goal, one as a base for astronomical observatories (radio, visible light, I think it would be a good place to try to detect gravity waves, test some dark matter detection theories) and it would be a good test of how viable it is to live on a very inhospitable world. Lessons learned from a Moon habitat will be useful for an eventual Mars habitat. I have no illusions about a Moon habitat being self sustaining over the long term.

As much as I would love to colonize Mars, it would be a lot easier to colonize the Moon. In both cases you need a pressure suit and you're going to be hit by lots of radiation. You'll be spending most of your time underground in both cases. And it's cheaper to get more stuff to the Moon to help people to survive.
