[LINK] "Spaced out"
Apr. 17th, 2013 03:36 pmVia Bruce Sterling I came across an article by Greg Klerkx at Aeon Magazine, "Spaced out". The author takes a look at the apparent paradox that in our post-Cold War era, just as the technology necessary to support a viable manned presence in space is appearing, interest in space colonization is dropping off. He draws interesting parallels with ocean colonization.
Most of what we have learned about living in space is that we should not live in space. We are designed for gravity; without it, strange things happen to both body and mind. For each month spent in space, humans can lose up to two per cent of their bone mass. This means that each day, for hours on end, the ISS becomes the world’s highest-flying gym to keep its occupants fit. But even with such precautions, some returning space travellers require months of rehabilitation to readjust to life on Earth. Others, despite having access to the best facilities and treatments available, experience headaches, sight loss, and undiagnosed physical and psychological frailty for the rest of their lives.
But these are mere hardships, not showstoppers, and those who’ve pioneered at the edges of human experience have always managed to endure them. Physiological challenges aside, life aboard the ISS is not unlike life on a submarine or in an Antarctic research station: isolated, cramped, and relentlessly task-focused. ‘But,’ the space futurist will say, ‘who is to say these limitations are permanent?’ After all, we might one day be able to create artificial gravity, which would significantly minimise the damage done to the human body in space. We might one day be able to build, launch and populate some version of the floating paradise envisioned by Tsiolkovsky and O’Neill, giving us greenery and companionship in space — and some measure of Earthly elbow room.
‘One day’ is the sustaining trope of today’s astropreneurs, and it is mother’s milk to the clever engineers and researchers at NASA and the European Space Agency, who continue to churn out studies and CGI animations pushing, ever pushing, for a humans-in-space future. One day, anything is possible: science and science fiction, hand in hand, have conspired to make us believe this is true. One day, living in space might be as easy as living on Earth.
But will it matter to anyone? That we might be able to live in space does not mean that we still want to, or that the arguments put forward for doing so will still resonate across the cultural landscape. Indeed, a closer look at the four space stations now in orbit reveals that the living-in-space dream is, in fact, in serious trouble.
No amount of spin can mask the incredible expense of the International Space Station, which has thus far cost an estimated $150 billion to build and operate. For that price, NASA could build, launch and operate several dozen Mars Curiosity rovers. The station’s scientific value is routinely criticised as being paltry, particularly when compared with other high-end science projects such the Large Hadron Collider, which was built for about $10 billion, less than a tenth of the price of the ISS. The ISS is routinely promoted as a stellar example of cross-cultural collaboration, but it’s unclear whether the multi-national consortium that runs it will keep it operating past 2020.
