MARSWALK ONE: First Steps on a New Planet addresses the question of why we should embark on a journey to Mars, documenting what the first human crew will do when they place their feet in the red dust of the planet. The book also addresses why we need to carry out these tasks and, more importantly, what a human crew could achieve that an automated mission could not. Understanding the clear benefits of sending a human crew to the surface of Mars, and how these benefits can be seen back on Earth, is the key to sustained long-term public and political support for the programme in terms of cash and commitment. The book accepts that the journey will be made, but does not specify precisely when. Flight time, and how to get to and from the planet are discussed briefly, to understand why the suggested duration spent at Mars is reasonable. The main objective of the work is to look at what science will be done on the surface – supported by orbital operations – and what hardware and technology will be employed to achieve the mission objectives. This analysis is drawn from previous experiences in manned and unmanned space programmes, including Apollo, Skylab, Salyut/Mir, Shuttle and ISS, Viking, Luna/Lunokhod, and recent Mars missions such as Pathfinder and Global Surveyor. In addition, new interviews with key personalities involved in planning Martian exploration, and discussions about current thoughts on what we need to accomplish on Mars when we get there, will provide a lively and thought provoking account that could generate fresh debate. When the decision is finally made to go to Mars, it will be made in the knowledge that most of the world knows why we are going and what benefits mankind will see for the effort. The authors’ primary objective is to begin this understanding.

This book explores the once popular idea of 'Flexible Path' in terms of Mars, a strategy that would focus on a manned orbital mission to Mars's moons rather than the more risky, expensive and time-consuming trip to land humans on the Martian surface. While currently still not the most popular idea, this mission would take advantage of the operational, scientific and engineering lessons to be learned from going to Mars's moons first. Unlike a trip to the planet's surface, an orbital mission avoids the dangers of the deep gravity well of Mars and a very long stay on the surface. This is analogous to Apollo 8 and 10, which preceded the landing on the Moon of Apollo 11. Furthermore, a Mars orbital mission could be achieved at least five years, possibly 10 before a landing mission. Nor would an orbital mission require all of the extra vehicles, equipment and supplies needed for a landing and a stay on the planet for over a year. The cost difference between the two types of missions is in the order of tens of billions of dollars. An orbital mission to Deimos and Phobos would provide an early opportunity to acquire scientific knowledge of the moons and Mars as well, since some of the regolith is presumed to be soil ejected from Mars. It may also offer the opportunity to deploy scientific instruments on the moons which would aid subsequent missions. It would provide early operational experience in the Mars environment without the risk of a landing. The author convincingly argues this experience would enhance the probability of a safe and successful Mars landing by NASA at a later date, and lays out the best way to approach an orbital mission in great detail. Combining path-breaking science with achievable goals on a fast timetable, this approach is the best of both worlds--and our best path to reaching Mars safely in the future.

“Manned Spaceflight Log” discusses over 40 recent spaceflights from September 2006 through September 2012, a time of great change in human spaceflight history. Following on from “Praxis Manned Spaceflight Log 1961-2006,” the authors continue the story until the end of September 2012, with new chapters detailing the development and accomplishments of human spaceflight, expanded tables and additional photographs, many in color, throughout. The book opens with a new foreword by Colonel Alfred M. Worden, USAF Retired, NASA Astronaut and CMP of Apollo 15, which reflects on the changing history of human spaceflight and the prospects for future operations. The first chapter explains how human spaceflight has approached the different challenges of exploring space and provided the hardware to meet those challenges. This chapter also describes the various attempts to reach orbital flight and the often confusing distinction between ballistic, sub-orbital, and so-called ‘astro-flights’ of the X-15 rocket research aircraft program. Chapter 2 recalls key historic moments and missions across five decades of human spaceflight. Each decade has provided useful lessons for the next and a foundation for future achievement. The new mission entries are collected in the third section in chronological order. A review of the next steps in human spaceflight, including plans to occupy the International Space Station well into the 2020s and the growth of the Chinese manned space program including a large space station and planned base on the Moon, is discussed in Chapter 4. The tables provide a complete up-to-date overview of human spaceflight operations and experience from April 1961 to September 2012 and a selected chronology of important milestones from those years. Completing the book is a comprehensive bibliography that lists all the major Springer-Praxis human spaceflight titles and other important works that provide the reader with a resource to continue further research.

Over the past 35 years more than 100 individual astronauts and cosmonauts have performed nearly 200 EVAs, (spacewalks), either singularly or in teams in Earth orbit, deep space or on the Moon. In 'Walking in Space: Development of Space Walking Techniques' the author, Dave Shayler, shows how hardware and crew members are prepared for, protected and supported during every EVA. He demonstrates how past experiences have led to improved training techniques and how this, in turn, has provided many successes and future developments.

The flight of Gemini 4 in June 1965 was conducted barely four years after the first Americans flew in space. It was a bold step by NASA to accomplish the first American spacewalk and to extend the U.S. flight duration record to four days. This would be double the experience gained from the six Mercury missions combined. This daring mission was the first to be directed from the new Mission Control at the Manned Spacecraft Center near Houston, Texas. It also revealed that: Working outside the spacecraft would require further study. Developing the techniques to rendezvous with another object in space would not be as straightforward as NASA had hoped. Living in a small spacecraft for several days was a challenging but necessary step in the quest for even longer flights. Despite the risks, the gamble that astronauts Jim McDivitt and Ed White undertook paid off. Gemini 4 gave NASA the confidence to attempt an even longer flight the next time. That next mission would simulate the planned eight-day duration of an Apollo lunar voyage. Its story is recounted in the next title in this series: Gemini 5: Eight Days in Space or Bust.

Die Angst vor dem sozialen Abstieg oder der Freudentaumel bei einem gewonnenen Fußballspiel: Emotionen sind nicht nur Ausdruck von Individualität und Persönlichkeit, sondern auch des sozialen Miteinanders und der gesellschaftlichen Verhältnisse. Im Rückgriff auf neurowissenschaftliche, psychologische und soziologische Emotionstheorien weist Christian von Scheve die tiefgreifende soziale Strukturierung von Affekten und Emotionen nach, zeigt den Einfluss von Gefühlen auf das soziale Handeln und analysiert die Regulation und soziale Kontrolle von Emotionen. Der Autor macht damit deutlich, wie wichtig Emotionen für die Entstehung und Reproduktion sozialer Ordnung sind.
