Here I thought the Solar Impulse was a breakthrough in solar powered flight, but NASA, the University of Washington, and Elon Musk of SpaceX (among others) have turned it to 11. With a new Fusion Driven Rocket (FDR) design, engineers may be able to cut the trip to Mars from 8 months to somewhere between 30 and 90 days. And what’s more: the engine operates via “magnetic inertial confinement fusion,” which, thankfully its designers explain, means that the rocket’s fusion reactor could be run by solar power alone–200 KW to be exact (an extremely feasible number). If flying from California to New York on solar energy as the Impulse team intends is impressive (and it is), then the FDR team’s plan for solar powered space flight is out of this world.
Colonizing Mars–part of Musk’s plan for making life multi-planetary to ensure that “the light of consciousness is not extinguished”–is undoubtedly among the more fantastical utopian visions of the future of humanity. Moreover, the team hopes to eventually make interplanetary travel so efficient that it’s commonplace. Skeptics and detractors (myself sometimes among them) may question the endeavor on “realist” or ethical grounds, claiming that either resource scarcity or social collapse is likely to preclude any significant opportunities for interplanetary migration, or that leaving the Earth behind is a defeatist reaction to socio-ethical challenges here at home, like stabilizing the modern ecological crisis. Indeed, I still think these points have some validity.
But Julian Simon’s infinite resource of human innovation again rears its head. The FDR is already in the pipeline, so to speak. And I’ll be the first to champion the triumphs of solar technology–especially when space travel is involved. Like so many others I’m sure, the prospect of an interstellar humanity speaks volumes to my inner Lewis and Clark–the passion for adventure and discovery too often squelched by the pervasive impact of human activity on and ubiquitous presence in what remains of natural world.
Interplanetary exploration and colonization promise new environments, mysteries, challenges, and questions–philosophical and otherwise. Should we leave Earth in the first place? What is the purpose of colonizing another planet? What would “environmental philosophy” mean if/when we depart from our environment of origin? What new responsibilities do we have to the non-human if and when we undertake massive martian geo-engineering projects like terraforming? If human beings create a living ecosphere on Mars, should we see ourselves as eco-constituents subsumed by a greater natural cycle as we are here on Earth, or, in a sense, should we regard ourselves as semi-gods, directly responsible for the martian natural cycle’s very existence? How should we organize a new society on Mars? Do Earthly political philosophies still apply? Once society on Mars is established, what responsibility will Martian humans have to their Earth-dwelling counterparts, and vice versa, if any? And should we today move further into the final frontier by small precautionary steps or giant proactionary leaps? Barring any unforeseen fatal design flaws or socio-political roadblocks, we could soon have our generation’s Neil Armstrong moment on the red planet. And we’d get there on solar power no less. To the sun god!
