Mars climate engineering using orbiting solar reflectors

The manned mission is seen as a first step towards a Mars surface exploration base-station and, later, establishing permanent settlement. The location and use of Mars's natural resources is vital to enable cost-effective long-duration human exploration and exploitation missions as well as subsequent human colonization. Planet resources include various crust-lodged materials, a low-pressure natural atmosphere, assorted forms of utilizable energy, lower gravity than Earth's, and ground placement advantages relative to human operability and living standards. Power resources may include using solar and wind energy, importation of nuclear reactors and the harvesting of geothermal potential. In fact, a new branch of human civilization could be established permanently on Mars in the next century. But, meantime, an inventory and proper social assessment of Mars's prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Mars with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Mars-related activities and a good starting point for young researchers

Terraforming

Terraforming is the process of making other worlds habitable for human life. Its counterpart on Earth—geoengineering— is receiving serious consideration as a way to address climate change. Contemporary environmental awareness and our understanding of climate change is influenced by science fiction, and terraforming in particular has offered scientists, philosophers, and others a motif for thinking in complex ways about our impact on planetary environments. This book asks how science fiction has imagined how we shape both our world and other planets and how stories of terraforming reflect on science, society and environmentalism. It traces the growth of the motif of terraforming in science fiction from H.G. Wells's The War of the Worlds (1898) to James Cameron's blockbuster Avatar (2009), in stories by such writers as Olaf Stapledon, Ray Bradbury, Robert Heinlein, Arthur C. Clarke, Frank Herbert, Ursula K. Le Guin, Ernest Callenbach, Pamela Sargent, Frederick Turner and Kim Stanley Robinson. It argues for terraforming as a nexus for environmental philosophy, the pastoral, ecology, the Gaia hypothesis, and the politics of colonisation and habitation. Amidst contemporary anxieties about climate change, terraforming offers an important vantage from which to consider the ways humankind shapes and is shaped by their world

Planetary Engineering Ethics: Mechanisms, Issues, and Consequences of Terraforming

This research and analysis paper addresses the extension of environmental ethics in the area of planetary engineering, specifically using the following three ethical viewpoints that inevitably shape our perceptions of the terraforming endeavors proposed to build our cosmological future appropriately: [1] environmental ethics analysis, [2] moral theories analysis (including utilitarianism, Respect for Persons ethics or “RP ethics,” and virtue ethics), and [3] risk analysis. The three ethical viewpoints, explained in “Concepts and Cases: Engineering Ethics. 6th Edition,” are used to elaborate justifications for or against terraforming beyond the mere theoretical explanations. To develop the justifications of the “intrinsic value” of terraforming, scientific evaluations, research, and experimentation in planetary engineering mechanisms, relevant issues addressed by proponents and opponents of terraforming, and potential consequences from the inherent risks involved in engineering implementations for space exploration, settlement, and modification are explored through each ethical lens and by using mainly Mars as the example planet of interest

Syncretia: a virtual geography for narrative playfulness

This paper examines the strategies and theories involved in the creation of a virtual habitat; the island Syncretia located in the virtual world of Second Life®. The island is comprised of a series of narrative/play installations, which can also be considered as "artistic environments". Syncretia should be seen as an endeavor for providing a context for play, storytelling and metaphor; involving an examination of virtual geographies, cyberpsychology/Presence studies, ludology and their relationship to objets trouvé or ready-made art/architectural objects which have been utilized to a substantial degree in the structuring of the visual/narrative language of Syncretia

System Engineering Analysis of Terraforming Mars with an Emphasis on Resource Importation Technology

This project uses System Engineering principles to delve into the viability of different methods for Terraforming Mars, with a comparison between Paraterraforming, Terraforming and Bioforming. It will then examine one subsystem that will be integral to the terraforming process, which is the space infrastructure necessary to import enough gases to recreate Earth’s atmosphere on Mars. It will analyze the viability of Chemical Rockets, Nuclear Rockets, Space Elevators, Skyhooks, Rotovators, Mass Drivers, Launch Loops and Orbital Rings for this subsystem and provide recommendations for an implementation plan
