Re: Open your mind!
Probably. I saw it and thought the intersection of "smart enough to have a net worth of $500k" and "dumb enough to sell it all for a one-way (*) trip to Mars" was probably quite small. However, I then read the first dozen of so comments and it appears that the El Reg readership are willing. I think there's something Darwinian going on there.
There are two reasons why it would be one-way. Firstly, you've sold everything on Earth and would return flat broke. Things would have to be near-terminal on Mars before you'd contemplate that.
Secondly, the Martian environment is nowhere near as hospitable as TV and films make out, and even if the rocket trip were absolutely free, $500k is not going to change that. You'll be living in a very confined space, eating your own shit, drinking recycled piss and breathing your neighbours farts, for the rest of your natural like. Happily, that's such an unhealthy lifestyle that you won't survive very long. In fact, you probably won't last as far as the next launch-window for the return trip to Earth. Even if you did, you'd be trampled to death in the rush.
