When I read an op-ed piece in the New York Times by physicist Lawrence Krauss at the end of August, 2009 proposing A One-Way Ticket to Mars, I was reminded that the history of bad ideas marches on, specifically those bad ideas derived from a technological vision of the future not anchored in human reality. Of course, bad ideas come and bad ideas go, but this one appears to have legs, as the publication in November of this study, To Boldly Go: A One-Way Human Mission to Mars, by Dirk Schulze-Makuch and Paul Davies in The Journal of Cosmology would indicate.
Having little hope of being around myself when and if this ill-considered idea is implemented, much less when it either reaches fruition or unravels, I take the opportunity to state my objections now.
Why a one-way trip?

As we might guess from the lead-lined aprons that are provided for our protection when we undergo dental x-rays, there are indeed ways to shield passengers during a long space voyage. Unfortunately the increase in the weight of a spaceship by including such shielding adds significantly to the cost of the mission. To make matters worse, the weight of fuel and provisions required by a two-way trip make the cost even more prohibitive, at least in our contemporary political and fiscal climate. So, first and foremost, a one-way journey is proposed to reduce the cost of a manned Mars mission, with the intention of putting it within practical reach relatively soon.

Motivations for a Mars colony
According to the authors there are several motivations for the establishment of a permanent human presence on Mars, whether using a one-way Mars mission as a kick-start or not. They are in brief:
- to offer humanity a "lifeboat" in the event of a mega-catastrophe here on Earth,
- to provide a base of operations for the scientific study of Mars, especially in the search for life forms that it might harbor, and a springboard for exploration of the outer solar system,
- and to serve as a "strong and uplifting theme for all of humanity" with all the political and social benefits that would supposedly imply.
That said, my criticisms of the scheme outlined in the Schulze-Makuch / Davies paper have less to do with whether a one-way mission achieves their stated limited technical goals, and more to do with whether it represents either a cost-effective or an ethical way to go about colonizing or even exploring Mars. I am also skeptical whether the imagined urgency that drives their dubious solution is in the least bit well-founded. These will be the concerns that I will address in the parts of this essay to follow.
