Well of course you haven't..the only one that comes close was just announced. The point is that phones are rapidly heading in that direction.
Unless it is realistic with a real chance of death should an air leak occur, or a system fails, such as Apollo 13, it will be almost meaningless. Of course, if the participants think there is a chance of death, even if a rescue is allowed that they don't know about, it might be OK and not taint the results.
Not only that, but they also know that they are not really going to mars. I would think the psychological effects would be much harder to endure if you knew that you were just stuck in a bunker on earth and could feasibly go back to your normal life at any point.
I'm likely quite ignorant on this subject-- but *how* can a day trader (or even group of them) kill a company?
They can't. Even if a large group of daytraders attempted to drive a stock price down, they aren't actually affecting the underlying value of the company. It would quickly become apparent that the stock price was not accurately priced and buyers would come in.
