The question I have is.....Why are all of these guys in such a rush to get to Mars?  It seems like in the last 4-5 years all of these guys with unlimited bank accounts want to go to Mars.  Why not just take a really sweet cruise?

Makes me wonder if they know something that we don't.

Google is doing it..In fact, Google even has a Google/mars

Virgin is doing it.

Amazon is in...

What's the deal? Is it because they've got so much money that they don't know what to do with it? Or is it something else?

There's no way all of these guys are "space" lovers and just want to piss away billions of dollars as a hobby.   I could have a trillion dollars, I'd never think...I want to go to Mars.
