Nuclear Technologies For Space Exploration

Provides details of a variety of radioisotope power systems, shows in what circumstances they surpass other power systems, and provides the history of the space missions in which they have been employed. The book also summarizes the use of on-board reactors and the testing done on reactor rocket thrusters.

Lt Col Downey, USAFR; Wing Cdr Forestier, RAAF; and Lt Col David E. Miller, USAF, advocate a feasibility study for reactors in space and explore a deeper problem with widespread societal rejection concerning the theoretical employment of nuclear technology in space. They point first to the mission enabling advantages of nuclear reactors in space--factors like light weight, high power, long life, and potentially lower costs. They see that nuclear-powered spacecraft would serve long-range NASA missions as well as permit effective hyperspectral satellites that would have profound benefits for the Department of Defense. The limiting factors for nuclear power in space are a compelling mission requirement and broad acceptance in popular support. Many opponents either have general doubts about such an undertaking or perceive cataclysmic dangers. A failure of a space launch carrying nuclear systems would produce something on the order of a 'dirty' nuclear bomb. Two things were clear to the authors. One, nuclear space developers must convince the public that they are capable of developing a safe and robust system. Two, because the political battle is primarily over perceived risks rather than empirically based understanding, employment of a values-focused decision strategy is necessary to convince the public and congressional leaders of the feasibility of a space nuclear program.

In 2003, NASA began an R&D effort to develop nuclear power and propulsion systems for solar system exploration. This activity, renamed Project Prometheus in 2004, was initiated because of the inherent limitations in photovoltaic and chemical propulsion systems in reaching many solar system objectives. To help determine appropriate missions for a nuclear power and propulsion capability, NASA asked the NRC for an independent assessment of potentially highly meritorious missions that may be enabled if space nuclear systems became operational. This report provides a series of space science objectives and missions that could be so enabled in the period beyond 2015 in the areas of astronomy and astrophysics, solar system exploration, and solar and space physics. It is based on but does not reprioritize the findings of previous NRC decadal surveys in those three areas.

Welcome to "Introduction to Nuclear Power in Space ". In the vast expanse of space exploration, where the challenges are as numerous as the stars themselves, the role of nuclear power cannot be overstated. This book serves as a comprehensive guide to understanding the pivotal role of nuclear technology in powering space missions, addressing the intricate nuances of nuclear cooling systems, space reactors, and propulsion technologies. As humanity ventures further into the cosmos, the demand for reliable and efficient power sources becomes increasingly urgent. Nuclear power stands at the forefront of this quest, offering unparalleled energy densities and longevity essential for extended missions beyond Earth's orbit. However, harnessing nuclear energy in the vacuum of space presents unique challenges and opportunities, which this book endeavors to explore in depth. From the fundamental principles of nuclear reactors to advanced propulsion systems capable of interstellar travel, each chapter delves into specific aspects of nuclear technology relevant to space exploration. We examine the intricacies of cooling systems, the adaptability of nuclear reactors to diverse mission requirements, and the cutting-edge innovations shaping the future of space propulsion. Moreover, safety is paramount in the utilization of nuclear power, particularly in the context of space missions where the stakes are high and the environments harsh. Throughout this book, we emphasize the importance of stringent safety protocols, redundancy measures, and contingency planning to mitigate risks associated with nuclear power in space. Furthermore, this book serves as a testament to the interdisciplinary nature of space exploration. From materials science to artificial intelligence, from propulsion engineering to cybersecurity, the integration of various fields is essential to unlocking the full potential of nuclear technology in space.
