Based on components already in existence, this manual details a reference design for an interplanetary spacecraft that is simple, durable, fully reusable and comprised mostly of water. Using such an accessible material leads to a spacecraft architecture that is radically simpler, safer and cheaper than conventional capsule based designs. If developed, the potential affordability of the design will substantially open all of the inner solar system to human exploration. A spacecraft that is comprised mostly of water will be much more like a living cell or a terrarium than a conventional rocket and capsule design. It will use water for many purposes before it is superheated in electric engines for propulsion, purposes which include radiation shielding, heat management, basic life support, crew consumption and comfort. The authors coined the term "spacecoaches" to describe them, as an allusion to the Prairie Schooners of the Old West, which were simple, rugged, and could live off the land.
What happens to you when you can’t walk for a year? When you can’t have sex? Or smell flowers? What happens if you vomit in your helmet during a space walk? Is it possible to survive a bailout at 17,000 miles an hour? Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh veg, privacy, beer. To answer these questions, space agencies set up all manner of quizzical and startlingly bizarre space simulations, and as Mary Roach discovers, it’s possible to preview space without ever leaving Earth. Packing for Mars takes us on a surreally entertaining voyage into the science of life in space and space on Earth.
Managerial Accounting is characterised by a strong pedagogical framework and a dynamic and practical approach that directly demonstrates how students can develop their careers in real life. The text introduces students to the underlying concepts and applications of management accounting tools based on the traditional allocation approach and absorption costing method, and uses ‘Staircase’ exercises in each chapter to build knowledge and help learners to link the content between chapters as they progress through the book. This title uses easy-to-understand, student-friendly language, uncomplicated examples, a logical discussion of concepts that matches student learning processes, and clear visual explanations that support student understanding.
