Download or read book Radioisotope Power Systems written by National Research Council and published by National Academies Press. This book was released on 2009-07-14 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft require electrical energy. This energy must be available in the outer reaches of the solar system where sunlight is very faint. It must be available through lunar nights that last for 14 days, through long periods of dark and cold at the higher latitudes on Mars, and in high-radiation fields such as those around Jupiter. Radioisotope power systems (RPSs) are the only available power source that can operate unconstrained in these environments for the long periods of time needed to accomplish many missions, and plutonium-238 (238Pu) is the only practical isotope for fueling them. Plutonium-238 does not occur in nature. The committee does not believe that there is any additional 238Pu (or any operational 238Pu production facilities) available anywhere in the world.The total amount of 238Pu available for NASA is fixed, and essentially all of it is already dedicated to support several pending missions-the Mars Science Laboratory, Discovery 12, the Outer Planets Flagship 1 (OPF 1), and (perhaps) a small number of additional missions with a very small demand for 238Pu. If the status quo persists, the United States will not be able to provide RPSs for any subsequent missions.

Download or read book Radioisotopes written by Nirmal Singh and published by BoD – Books on Demand. This book was released on 2011-10-21 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book Radioisotopes - Applications in Physical Sciences is divided into three sections namely: Radioisotopes and Some Physical Aspects, Radioisotopes in Environment and Radioisotopes in Power System Space Applications. Section I contains nine chapters on radioisotopes and production and their various applications in some physical and chemical processes. In Section II, ten chapters on the applications of radioisotopes in environment have been added. The interesting articles related to soil, water, environmental dosimetry/tracer and composition analyzer etc. are worth reading. Section III has three chapters on the use of radioisotopes in power systems which generate electrical power by converting heat released from the nuclear decay of radioactive isotopes. The system has to be flown in space for space exploration and radioisotopes can be a good alternative for heat-to-electrical energy conversion. The reader will very much benefit from the chapters presented in this section.

Download or read book NASA Space Technology Roadmaps and Priorities written by National Research Council and published by National Academies Press. This book was released on 2012-06-07 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's Office of the Chief Technologist (OCT) has begun to rebuild the advanced space technology program in the agency with plans laid out in 14 draft technology roadmaps. It has been years since NASA has had a vigorous, broad-based program in advanced space technology development and its technology base has been largely depleted. However, success in executing future NASA space missions will depend on advanced technology developments that should already be underway. Reaching out to involve the external technical community, the National Research Council (NRC) considered the 14 draft technology roadmaps prepared by OCT and ranked the top technical challenges and highest priority technologies that NASA should emphasize in the next 5 years. This report provides specific guidance and recommendations on how the effectiveness of the technology development program managed by OCT can be enhanced in the face of scarce resources.

Download or read book Spacecraft Power Systems written by Mukund R. Patel and published by CRC Press. This book was released on 2023-12-12 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of Spacecraft Power Systems is a comprehensive coverage of the fundamentals, design trades, components, controls, and operations of spacecraft power systems based on the real-world design and operations of spacecraft that have successfully flown for decades. It also includes emerging high-voltage, high-power systems for in-space propulsion for interplanetary travel. With new and updated chapters, sections, and discussions, the second edition covers up-to-date high-voltage, MW-scale electric propulsion, updated PV and battery systems, spacecraft power components, power electronics, and their architectures and operations. This book also presents the latest in spacecraft design processes and trades, controls, operations, and protection. This book is intended for senior undergraduate and graduate students in mechanical, aerospace, and electrical engineering taking courses in Space Systems, Space Engineering, and Spacecraft Power Systems, as well as for practicing aerospace and power engineers and managers who are designing, developing, and operating spacecraft power systems.
