More than any at other conferences I have attended, participants in the annual Mars Society meeting, which was held this year in Boulder, Colorado (August 2013) — their 16th such meeting, my first — like to nod their agreement. In contrast, attendees at the meetings I more regularly visit concerning the ecological fate of the planet signal their comprehension with aghast motionlessness. When Robert Zubrin, director of the (currently Earth-bound) Mars Society, announced in Boulder this summer, that Mars is our future, the audience nodded. Rather, I should say, we nodded.
Not only is a manned mission to Mars technically feasible with existing, or almost-existing, technology but Zubrin insists that it is desirable for us to go to Mars sooner rather than later. Zubrin was reasserting an argument that he has been making for some time. In The Case for Mars — The Plan to Settle the Red Planet and Why We Must (1996) he set out his blueprint for Mars Direct, a plan for manned missions to Mars that would pave the way for colonization and would be both cost-effective and possible with current technology.
Why should we go to Mars? There are economic arguments in favor of us doing so, Zubrin claims. Certain elements, such as deuterium used in nuclear reactors, are hyper-available elements on Mars could be profitably used on Earth. Additionally, rare metals: platinum, gold and silver, can be
recovered from Mars and returned to Earth. The economic arguments are important to the case for Mars, but central to Zubrin’s argument, is what exploration of Mars says about us as a species. We should go because we can; it’s who we are. According to Zubrin “virtually every element of significant interest to industry is known to exist on the Red Planet”. Of all the planets in our solar system Mars has by far the greatest potential for self-sufficiency. The resources on Mars will cater for both initial colonists and for the subsequent expansion of a civilization on the Red Planet. For example, subsurface accumulation of water can provide supplies to explorers. Moreover, the colonization of Mars “reaffirms the pionee
ring character of our society.” Drawing parallels to Roald Amundsen’s successfully traversing the wilderness of Canada’s Northwest Passage in 1903, an expedition which adopted a “live off the land” strategy, Zubrin appeals to a pioneering grit and esprit in forging his plans for Mars. Summarizing his reasons for colonizing Mars, Zubrin wrote, “For our generation and many to follow Mars is the New World”. Considering that as of the 9th September 2013 more than 200,000 have applied for a one-way settlement mission to Mars over at the Mars One website, it would seem that Zubrin’s assessment is confirmed.
