Re: Space X and the prospects of Mars colonization.

That will never be the case.

There are no materials which are cheap enough on Mars and expensive enough on Earth to every make freight plausible.

Haha, you say that as if there's a building supplies shop on Mars. How can something be cheap or expensive on Mars? I don't think they have their own economy over there. If they do, they're doing a very good job of hiding it. Haha! I think what you're trying to say is that there's nothing on Mars that could be sold for enough on Earth to make it worth the trip. I could see that being the case.

"How can something be cheap or expensive on Mars?"

Try jumping to Mars. Get the latest position of Mars from some star chart, go out into the parking lot at just the right time, and jump real hard. Did you make it to Mars? No? Well how about this?

Buy an airplane and fly to Mars. I mean, all it will cost you is the price of the airplane and fuel. Did that work? No? Well, how about this.

Crawl on top of a NASA Saturn rocket, and have NASA fly you to Mars. Did it work? Was it cheap? No? Well, you could always go back to a bottle rocket idea. It's cheaper that way.

What is there on Mars that is going to justify the expense of going there? So far we haven't found any justification for the expense of sending our robot vehicles there. So far it has all been a waste of society time and money. So far it has done more to increase poverty on earth than we could ever imagine.

Cool

I was just responding to Spendulus's comment. He/she said that, "There are no materials which are cheap enough on Mars and expensive enough on Earth to every make freight plausible." It obviously costs money on Earth to get to Mars. I just thought it sounded funny to talk about the cost of things on Mars. They can't actually have a financial cost if they have no economy. It's sort of hard to tell if investing in trips to Mars has been a waste or not. Time will tell. It ain't over 'til the fat lady sings, as they say.
