For the record, in case any of you are or know eccentric billionaires, I would ABSOLUTELY be willing to go to Mars, regardless of whether or not there were a way to get back. In fact, that would be a certain part of the appeal. Surely the need for this fatalistic derring-do of mine is of vital importance toward future colonization, right? Surely a Mars mission needs an introspective (yet appropriately sociable) designer/zinester to document the journey and the inevitable decline of the first colony, right? How else would future generations learn? I already have a thing for space suits! SEND ME TO MARS, DAMNIT!
