In March 2000, NASA's Office of Space Flight asked the Aeronautics and Space Engineering Board of the National Research Council to perform an independent assessment of the space solar power program's technology investment strategy to determine its technical soundness and its contribution to the roadmap that NASA has developed for this program. The program's investment strategy was to be evaluated in the context of its likely effectiveness in meeting the program's technical and economic objectives.

Communication satellites are a $144 billion industry. Is there any space-based industry that could possibly beat that market? 'Solar Power Satellites' shows why and how the space satellite industry will soon begin expanding its market from relaying signals to Earth to generating energy in space and delivering it to the ground as electricity. In all industrialized nations, energy demand is growing exponentially. In the developing world, the need for energy is as basic as food and water. The Sun's energy is available everywhere, and it is non-polluting. As business plans demonstrate its technical feasibility, commercial potential, and environmental acceptability, every country on Earth will look to space for the power it needs.

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?"

A look at ways to collect solar power in space with satellites and beam that power down to Earth to supplement our other sources of electricity. In addition, this is a look at novel ways, to say the least, to construct those satellites. The witnesses at these Senate hearings envision a time when space will be the scene of bustling activity. They foresee construction of gigantic facilities that will provide the world with energy, which is an essential and increasingly costly part of our industrial society.

Space is a contested domain for its very nature and today it is evidently becoming an increasingly important enabler of economic and military power. An increasing number of actors, infrastructures and technologies deployed in space also raises concerns for safety and security, especially in cyberspace. Many countries are striving to achieve space capabilities and autonomous access to space, and this ishaving a tremendous geopolitical impact, especially since space is emerging as an increasingly critical military and strategic domain. The development of the new space economy, which is increasingly involving the private sector and many industrial actors and services, will also be a game changer for the international economy. The space race likewise implies disruptive technologies that could contribute massively to the energy and digital transitions, accelerating solutions that could benefit humanity. A new international governance system for space is therefore needed urgently, considering that the current rules are no longer able to respond to a sector evolving at such a rapid pace. Which actors are leading the race? Which economic sectors could benefit the most and what could the new space economy mean for the world? How is space emerging as a military domain against a backdrop of increasing international tensions? What would a new system of global governance for space look like?

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,
