Mars or Bust! One-Way Trip to the Red Planet Could Kick-start Colonization

The vast plains of Mars may be the most promising place beyond Earth for human colonization, but is it enough for a one-way trip to the Red Planet? Two researchers seem to think so.
In an article published this month in the Journal of Cosmology, environmental scientist Dirk Schulze-Makuch and physicist Paul Davies argue that a manned one-way mission to Mars would not only make economical sense, but mark the beginning of long-term colonization of the planet.
The researchers contend that while a manned flight to Mars and back is technically feasible now, the steep financial and political costs make such a mission unlikely to launch anytime soon. And since the greatest portion of expenses would be incurred by the safe return of the crew and spacecraft to Earth, the authors conclude that a manned one-way mission to Mars would both cut costs and help initiate Martian colonization.
