From the standpoint of being able to cannibilize one's spaceship and devote all
the foods and goods for a one way trip instead of worrying about fuel and food
supplies for a return trip, it could almost double the ability of a permanent
station on Mars. The initial space ships could double as temporary habitats.
The one-way trip is something to consider and review at least before dismissing
it out of hand.
The key thing is that out of all the qualified persons who might go to Mars, the
only ones who would go on one-way trips are those who want to go. If they want
to go that way, then, fine, it's their choice.
I recommend that the authors of this idea be first to go. After all, they seem
to think that it is "no big deal".
fwiw, this is a pretty old idea. The whole idea of a 2way trip to Mars is pretty
unlikely, considering the tremendous amount of energy required to escape Mars's
gravity well. I personally find the idea intriguing. It really revives the
original spirit of an Astronaut, however, recalling days when when space seemed
almost unconquerable and dangerous and the job of astronaut life-threatening.
