The Ethics of Terraforming and Areoforming in an Age of Climate Change
Engineering Planets, Engineering Ourselves: The Ethics of Terraforming and Areoforming in an Age of Climate Change Patrick D. Murphy (University of Central Florida)1 Abstract The concept of terraforming, the engineered transformation of alien planets into habitats suitable for human settlement, has taken on new meaning in science fiction and contemporary culture as climate change has indicated that human beings are currently transforming this planet but without a clear plan for sustaining inhabitability. Literary depictions by Kim Stanley Robinson of both climate change and terraforming raise ethical questions about the engineering of this and other planets, while the science fiction novels of Joan Slonczewski raise ethical questions about engineering human beings to adapt to alien environments. Together, they provide ways of thinking about the intertwined ethical questions of engineering the biosphere and engineering the species in the context of human and environmental sustainability. In particular, some works, such as the novels of Karen Traviss, raise the issue of how much the human species might have to engineer itself to pay the price of its unplanned engineering of planet Earth. Nearly twenty years ago Bill McKibben claimed that "we are at the end of nature" (8). In support of this seemingly hyperbolic statement, he referred to a 1957 scientific paper which claimed that "Human beings are now carrying out a large scale geophysical experiment" (qtd. in McKibben 10), by pumping rapidly increasing amounts of carbon dioxide into the atmosphere. 1 Patrick Murphy, Department of English, University of Central Florida, Building: CNH301 P.O.

A monstrous tripod, higher than many houses, striding over the young pine trees, and smashing them aside in its career; a walking engine of glittering metal, reeling now across the heather, articulate ropes of steel dangling from it, and the clattering tumult of its passage mingling with the riot of the thunder. A flash, and it came out vividly, heeling over one way with two feet in the air, to vanish and reappear almost instantly, as it seemed with the next flash, a hundred yards nearer. - H.G.

The Past Decade and the Future of Cosmology and Astrophysics
Towards a New Enlightenment? A Transcendent Decade The Past Decade and the Future of Cosmology and Astrophysics Martin Rees Martin Rees is a cosmologist and space scientist. After studying at Cambridge University, he held various posts in the UK and elsewhere, before returning to Cambridge, where he has been a professor, Head of the Institute of Astronomy, and Master of Trinity College. He has contributed to our understanding of galaxy formation, black holes, high-energy phenomena in the cosmos, and the concept of the multiverse. He has received substantial international recognition for his research. He has been much involved in science-related policy, being a member of the UK’s House of Lords and (during 2005–10) President of the Royal Society, the independent scientific academy of the UK Martin Rees and the Commonwealth. Apart from his research publications, he writes and University of Cambridge lectures widely for general audiences, and is the author of eight books, the most recent being On the Future (2018). Recommended books: Universe, Martin Rees, Dorling Kindersley, 2012; On the Future, Martin Rees, Princeton University Press, 2018. In the last decade, there has been dramatic progress in exploring the cosmos. Highlights include close-up studies of the planets and moons of our Solar System; and (even more dramatic) the realization that most stars are orbited by planets, and that there may be millions of Earth-like planets in our Galaxy. On a still larger scale, we have achieved a better understanding of how galaxies have developed, over 13.8 billion years of cosmic history, from primordial fluctuations. -

Inventory of CO2 Available for Terraforming Mars
PERSPECTIVE https://doi.org/10.1038/s41550-018-0529-6 Inventory of CO2 available for terraforming Mars Bruce M. Jakosky 1,2* and Christopher S. Edwards3 We revisit the idea of ‘terraforming’ Mars — changing its environment to be more Earth-like in a way that would allow terres- trial life (possibly including humans) to survive without the need for life-support systems — in the context of what we know about Mars today. We want to answer the question of whether it is possible to mobilize gases present on Mars today in non- atmospheric reservoirs by emplacing them into the atmosphere, and increase the pressure and temperature so that plants or humans could survive at the surface. We ask whether this can be achieved considering realistic estimates of available volatiles, without the use of new technology that is well beyond today’s capability. Recent observations have been made of the loss of Mars’s atmosphere to space by the Mars Atmosphere and Volatile Evolution Mission probe and the Mars Express space- craft, along with analyses of the abundance of carbon-bearing minerals and the occurrence of CO2 in polar ice from the Mars Reconnaissance Orbiter and the Mars Odyssey spacecraft. These results suggest that there is not enough CO2 remaining on Mars to provide significant greenhouse warming were the gas to be emplaced into the atmosphere; in addition, most of the CO2 gas in these reservoirs is not accessible and thus cannot be readily mobilized. As a result, we conclude that terraforming Mars is not possible using present-day technology. he concept of terraforming Mars has been a mainstay of sci- Could the remaining planetary inventories of CO2 be mobi- ence fiction for a long time, but it also has been discussed from lized and emplaced into the atmosphere via current or plausible 1 a scientific perspective, initially by Sagan and more recently near-future technologies?
