A human mission to Mars is feasible, but hugely expensive. A 1-way human mission to Mars would cut the costs several fold but ensure at the same time a continuous commitment to the exploration of Mars in particular and space in general. It would require not only major international cooperation, but a return to the exploration spirit and risk-taking ethos of the great period of Earth exploration, from Columbus to Amundsen, but which has nowadays being replaced with a culture of safety and political correctness.
