TERRAFORMING MARS This book provides a thorough scientific review of how Mars might eventually be colonized, industrialized, and transformed into a world better suited to human habitation. The idea of terraforming Mars has, in recent times, become a topic of intense scientific interest and great public debate. Stimulated in part by the contemporary imperative to begin geoengineering Earth, as a means to combat global climate change, the terraforming of Mars will work to make its presently hostile environment more suitable to life—especially human life. Geoengineering and terraforming, at their core, have the same goal—that is to enhance (or revive) the ability of a specific environment to support human life, society, and industry. The chapters in this text, written by experts in their respective fields, are accordingly in resonance with the important, and ongoing discussions concerning the human stewardship of global climate systems. In this sense, the text is both timely and relevant and will cover issues relating to topics that will only grow in their relevance in future decades. The notion of terraforming Mars is not a new one, as such, and it has long played as the background narrative in many science fiction novels. This book, however, deals exclusively with what is physically possible, and what might conceivably be put into actual practice within the next several human generations. Audience Researchers in planetary science, astronomy, astrobiology, space engineering, architecture, ethics, as well as members of the space industry.
The only work to date to collect data gathered during the American and Soviet missions in an accessible and complete reference of current scientific and technical information about the Moon.
Moon Rocks and Minerals compiles the important findings that have resulted from the first study of the Apollo 11 lunar rocks, including preliminary data on Apollo 12 lunar samples. The compiled study samples and proposals on the lunar rocks are categorized into four general categories— mineralogy and petrology, chemical and isotope analyses, physical properties, and bioscience and organic geochemistry. In these categories, this book specifically discusses the types and mineralogy of lunar rocks and soils; chemistry of samples brought by Apollo 11 and 12; and experimental studies and origin of the lavas. The age of the lunar rocks, isotope studies, cosmic ray, and solar wind effects and origin of the moon are also deliberated. This text also covers the examination of lunar samples for the presence of biochemical organic compounds in the general context of the possibility of extraterrestrial life. This publication is beneficial to scientists of disciplines such as geochemistry, cosmochemistry, mineralogy, and geophysics.
The BBC’s “face of space” explores all things lunar in this comprehensive guide to the folklore, facts, and possible futures of our only natural satellite. Have you ever wondered if there are seasons on the moon or if space tourism will ever become widely accessible? So has Dr. Maggie Aderin-Pocock, astronomer and host of the BBC’s docuseries, The Sky at Night. In this lucidly written guide, Aderin-Pocock takes readers on a fascinating lunar journey. Aderin-Pocock begins with a basic overview—unpacking everything from the moon’s topography and composition to its formation and orbit around the Earth. She examines beliefs held by ancient civilizations, the technology that allowed for the first moon landing, a brief history of moongazing, and how the moon has influenced culture throughout the years. Looking to the future, she delves into the pros and cons of continued space travel and exploration. Throughout the book are sidebars, graphs, and charts to enhance the facts as well as black-and-white illustrations of the moon and stars.

Protection of Deposited Molecules and Present Location of Lunar Deposits of Organic Matter During the time of deposition, the lunar atmosphere would have inhibited thermo- and photo-dissociation of the deposited molecules. As the secondary lunar atmosphere gradually escaped to space, and outgassing declined, the rate of atmospheric organic synthesis decreased and the penetration of short wavelength radiation to the surface increased. In addition, the surface temperature gradually rose, due both to the loss of the insulating atmosphere, and to radioactive heating. The effect of heat and ultraviolet light on the molecules described above is most remarkable. Although the second law of thermodynamics is obeyed, a large fraction of the molecules, with activation energies supplied, partake in organic syntheses of a higher order of complexity. Polypeptides arise from amino acids, hydrocarbon dimers and trimers form long- chain polymers, and in general very complex organic molecules are constructed (v., e.g., Oparin, 1957; Fox, 1956). Finally, because complex molecules are more resistant to heat and radiation than are simpler molecules (at least in part due to the Franck- Rabinowitch cage effect), the syntheses are biased towards the net production of the most complex organic molecules (Gordy, Ard, and Shields, 1955; Sagan, 1957). Although continued radiation and high temperatures would lead to the eventual destruction of all these molecules, we must remember that meteoritic matter was falling into the lunar atmosphere throughout the period of organic synthesis. Whipple (1959) estimates that about 50 gm cm2 of meteoritic matter falls on the Moon each 108 years at present rates of infall. In addition, it is almost certain that the rate of meteoritic infall on the Moon in primi...
