Pretty interesting. I'm sure a lot of people would be interested in a one way ticket to Mars if we could somehow make it livable over there.. I know I am!

It's not like a one way trip is unprecedented in human history. Many of the Europeans coming to North America did it one way to conditions that were very much more primitive than the old world.

For those Europeans, there was still the option of turning it into a round trip. Granted, it was probably an expensive and arduous option, and required a ship in port ready and willing to take you, but it was there.

Right now, a one-way trip to Mars really is a one-way trip. That is, until we can put enough provisions up there to get a ship back out of that gravity well.

And keep the occupants alive long enough to get back here.

Some Europeans had the option. Many had a literal one way trip (no money / resources or the whole go-to-new-world-or-go-to-jail thing).
