Book excerpt: During energy crisis at the end of the Sixties, a new idea to exploit solar energy arose: Solar Power Satellites. These satellites need a huge surface to collect enough solar energy to be beamed on Earth by means of a microwave power transfer system. Different concepts appeared during last forty years and a lot of studies addressing the SPS economical feasibility have been published. In this work a particular concept is considered, the JAXA Reference Concept 2003. It is a formation flying SPS, composed by two reflectors and a central array panel. The objective of the work is to study two major problems this concept presents. Due to its dimensions, the satellite orbit will suffer from important orbital perturbations and since formation flying satellites need a tight orbit control, the first task is to derive an analytical approximation to perform relative perturbed orbit propagation for formation flying satellite. This objective is pursued starting from a H. Schaub’s formulation in which formation flying satellites unperturbed orbit is described by means of an approximated relation function of orbital element differences. This formulation is merged with another approach, developed in a previous work, which gives, analytically, orbital parameters variation when a perturbation acts on the spacecraft. The result is a very interesting algorithm, able to perform the assigned task with a relative error lower than 3% over one simulated orbit. The second objective concerns structural control. It is not possible to consider these huge satellites as rigid bodies, first natural frequencies will be certainly excited during operations. So that, the second task is the study of actuator placement optimization for flexible satellites, very useful for tight pointing requirements. A FEM model is developed modeling the SPS as a frame of beams and a global controllability index is obtained combining modal controllability and component cost analysis. The maximization of this parameter,

Book excerpt: This book makes the case for Space Solar Power; recounting the history of this fascinating concept and summarizing the many different ways in which it might be accomplished. The book describes in detail a highly promising concept - SPS-ALPHA (Solar Power Satellite by means of Arbitrarily Large Phased Array) - and presents a business case comprising applications in space and markets on Earth. The book explains how it is possible to begin now with technologies that are already at hand, while developing the more advanced technologies that will be needed to deliver power economically to markets on Earth. The Case for Space Solar Power concludes by laying out a path forward that is both achievable and affordable: within a dozen years or less, the first multi-megawatt pilot plant could be in operation. Getting started could cost less than $10 million over the first 2 years, less than $100 million over the next half dozen years. Given that space solar power would transform our future in space, and might provide a new source of virtually limitless and sustainable energy to markets across the world, the book poses the question, "Why wouldn't we pursue space solar power?"

This book was released on 2009-07-24 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development is challenged by, at least until 2050, a strong population, more severe environmental strains, growing mobility, and dwindling energy resources. All these factors will lead to serious consequences for humankind. Inadequate agricultural resources, water supply and non renewable energy sources, epidemics, climate change, and natural disasters will further heavily impact human life. The European Space Policy Institute (ESPI) sheds a new light on threats, risks and sustainability by combining approaches from various disciplines. It analyzes what could be the contribution of space tools to predict, manage and mitigate those threats. It aims at demonstrating that space is not a niche but has become an overarching tool in solving today’s problems.
