"Earth is not well. The promise of starting life anew somewhere far, far away--no climate change, no war, no Twitter--beckons, and settling the stars finally seems within our grasp. Or is it? Kelly and Zach Weinersmith set out to write the essential guide to a glorious future of space settlements, but after years of research, they aren't so sure it's a good idea. Space technologies and space business are progressing fast, but we lack the knowledge needed to have space kids, build space farms, and create space nations in a way that doesn't spark conflict back home. In a world hurtling toward human expansion into space, A City on Mars investigates whether the dream of new worlds won't create nightmares, both for settlers and the people they leave behind. In the process, the Weinersmiths answer every question about space you've ever wondered about, and many you've never considered: Can you make babies in space? Should corporations govern space settlements? What about space war? Are we headed for a housing crisis on the Moon's Peaks of Eternal Light--and what happens if you're left in the Craters of Eternal Darkness? Why do astronauts love taco sauce? Speaking of meals, what's the legal status of space cannibalism?"--Publisher marketing.

The Bioethics of Space Exploration provides a comprehensive discussion of the possible bioethical issues and challenges that may arise when considering future long-term space missions. Because of numerous threats within the space environment, many consider the concept of radically modifying humans to be a serious and perhaps even necessary option. Konrad Szocik presents what types of ethical and bioethical challenges may await participants on commercial, scientific, and colonizing missions, and provides a new perspective into the potential for radical biomedical technologies.

Following on from Part 1, which was highly acclaimed by the space community, this peer-viewed book provides detailed insights into how space and popular culture intersect across a broad spectrum of areas, including cinema, music, art, arcade games, cartoons, comics, and advertisements. This is a pertinent topic since the use of space themes differs in different cultural contexts, and these themes can be used to explore various aspects of the human condition and provide a context for social commentary on politically sensitive issues. With the use of space imagery evolving over the past sixty years of the space age, this topic is ripe for in-depth exploration. Covering a wide array of relevant and timely topics, the book examines the intersections between space and popular culture, and offers accounts of space and its effect on culture, language, and storytelling from the southern regions of the world.

This book describes the development and design of a unique combined data and power management infrastructure for small satellites. This new edition became necessary because in the frame of the system's impressive evolution from an academic prototype to one of today's most advanced core avionics, many elements were upgraded to their next technology generation and diverse new components complement the upgraded design. All elements are presented in updated respectively new chapters.This modular infrastructure was selected by the Swiss start-up ClearSpace SA for ESA's first mission ClearSpace-1 to remove space debris. Furthermore it is the baseline for the Thai national satellite development program and is used by an increasing number of universities worldwide for research studies.

The author proposes theoretical concept validation of a staged compression gun able to accelerate projectiles and spacecraft to Keplerian velocities and even to relativistic velocities. The fundamental concept is to use a space based linear accelerator to propel small fission/fusion devices to produce a propellant runway. Prior theoretical art explores the basic concepts of fusion runways. Accordingly, nuclear fusion fuel pellets or other fuel pellets would be distributed along a substantially linear path for interception by a spacecraft. The fuel pellets would then be captured and processed in nuclear fusion reactors or otherwise detonated in proximity to a spacecraft. While various means of distributing fuel pellets for deep space travel has been proposed, this paper proposes novel methods of dispensing the pellets.

Herein Volume 1, we explore principally relativistic rocket flight in so-called astral planes.Accordingly, we include formulas for relativistic rocket flight performance, fuel supplies, shielding, and the like. In this volume, we cover more or less conventional relativistic rockets and astral planar analogs.We approach the notions of astral planar flight in formulaic detail in the following manners.First, we consider astral planar variables in associated equations and formulas as derived from axiomatic modifications of equations and formulas for conventional relativistic rocket flight.Second, we assume closely parallel formulaic analogs with known relativistic flight formulas under the assumption that since it appears that the laws of physics in our physical realm are the way they are because that is the way they must be for the physical cosmos to per due.Third, we assume that the fundamental constants in astral planar laws are analogs of those in the physical realm and indeed must be so as to provide stability in astral planes and associated rocket travel.Fourth, we assume that no-go theorems such as the chronological protection conjecture and the certainty of light-speed limits in our physical universe have analogs in astral planes.Fifth, we assume that the operation of fiat such as rockets in astral planes operate in close analogies with the operation of such craft as would occur in our physical realm.Sixth, we assume that except for higher levels of intellectual, emotional, social, and psychological functioning in astral planes compared to that of us in the physical realm, astral planar proverbial landscape is similar looking to that of present day physicality. We base this assumption on the common and repeated content of personal accounts of near death experiences and the like and how such experiences are similar to those in the physical world such as the perception of colors, the existence from lush grassy meadow, flowers, animal playing together in the presence of Jesus, and the like.Astral planes are assumed to come in a plethora of levels. The first level is most closely analogous to the physical realm accept at a higher more refined level. In Volume 1, we concern our formulas, natural constants, topologies, geometries and other kinematic aspects in a first level of astral planes as more closely related to that in the visible physical realm.The book is divided into two main parts. The first part considered conventional relativistic rocket flight in the physical realm while the second part considers analogs in a first level of astral planes.In many cases for the portion of the book on astral planar rocket flight, we do not always specifically replace word for word of, say for instance, relativistic rocket with astral-planar relativistic rocket, nor other words of primary themes. However, the context in which dual wordage is provided is made clear in the astral-planar analogues.In Volume 1, we consider astral-planar analogs of relativistic rocket flight in a first level and category of performance, such as for example, conventional relativistic rocket flight in the range of Lorentz factors ranging from just a bit greater than one to values on the order of billions and trillions.

Die Mikrogravitationsumgebung ist eine hervorragende Plattform für Forschung, Anwendung und Ausbildung. Es ist eine Umgebung, in der Schwerelosigkeit vorausgesetzt wird. Alle Experimente, die unter 1G durchgeführt werden, können unter Mikrogravitation wiederholt werden, wenn sie verfügbar sind, ebenso können neue Experimente formuliert werden, um die unter 1G erzielten Ergebnisse mit der Mikrogravitation zu vergleichen. Weltraumtaugliche Experimente in der Mikrogravitation sind ungewöhnlich und teuer, was die Zahl der Forscher in diesem Bereich einschränkt. Auf der Erde stehen Plattformen zur Verfügung, die im freien Fall, in Ballons, Sondierungsraketen usw. Schwerelosigkeit erfahren; diese Plattformen reagieren schnell, während einige Experimente nur langsam auf die Mikrogravitation reagieren. Dies führte zur Entwicklung mehrerer alternativer bodengestützter Geräte zur Simulation der Mikrogravitation bzw. der Aufhebung der Schwerkraft. Clinostat ist eines dieser Geräte. In diesem Buch werden die möglichen Proben und die experimentellen Variablen für den 2D-Klinostat beschrieben. Außerdem werden die Vorteile der Mikrogravitationsforschung im Hinblick auf ihre Anwendung in der Ausbildung und in den Biowissenschaften (Landwirtschaft, Pharmazie, Mikrobiologie, Medizin und Biotechnologie) am Beispiel des Klinostats aufgezeigt.

Che cosa ha motivato la conoscenza e lo sviluppo dell'uomo? La risposta è semplice, perché da sempre la curiosità è il motore dello sviluppo della nostra esistenza e delle diverse civiltà. Questo concetto è stato favorito dall'osservazione a distanza e dallo spazio con le informazioni fornite dai satelliti artificiali creati proprio per lo studio e la localizzazione dei vari fenomeni e cambiamenti che avvengono sulla superficie terrestre, e che nella nostra epoca puntano a un lavoro congiunto e collaborativo tra diverse specialità.

Questo studio ha sviluppato principalmente un metodo di mappatura e ha valutato il rischio di inondazioni in un ambiente urbano, adattato al contesto di urbanizzazione anarchica e di servizi igienici scarsamente controllati nel comune di Abobo (Abidjan, Costa d'Avorio). È stato suddiviso in tre obiettivi specifici: In primo luogo, l'identificazione dei fattori di pericolosità e vulnerabilità all'origine delle alluvioni; in secondo luogo, la mappatura delle aree a rischio di alluvione, basata sull'analisi multicriteriale AHP di Saaty; in terzo luogo, la modellazione del sistema di deflusso delle precipitazioni, alla scala del bacino idrografico di Sagbé-Anonkoi Kouté, al fine di stabilire una proiezione delle alluvioni su periodi di 5, 25, 50 e 100 anni, con l'obiettivo di aiutare i decisori a prendere decisioni anticipate.
