Available in PDF, EPUB and Kindle. Book excerpt: Nuclear power is the next enabling technology in manned exploration of the solar system. Scientists and engineers continue to design multi-megawatt power systems, yet no power system in the 100 kilowatt, electric range has been built and flown. Technology demonstrations and studies leave a myriad of systems from which decision makers can choose to build the first manned space nuclear power system. While many subsystem engineers plan in parallel, an accurate specific mass value becomes an important design specification, which is still uncertain. This thesis goes through the design features of the manned Mars mission, its power system requirements, their design attributes as well as their design faults. Specific mass is calculated statistically as well as empirically for 1-15MWe systems. Conclusions are presented on each subsystem as well as recommendations for decision makers on where development needs to begin today in order for the mission to launch in the future.

Download or read book Conceptual Studies on the Integration of a Nuclear Reactor System to a Manned Rover for Mars Missions written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-17 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiyear civilian manned missions to explore the surface of Mars are thought by NASA to be possible early in the next century. Expeditions to Mars, as well as permanent bases, are envisioned to require enhanced piloted vehicles to conduct science and exploration activities. Piloted rovers, with 30 kWe user net power (for drilling, sampling and sample analysis, onboard computer and computer instrumentation, vehicle thermal management, and astronaut life support systems) in addition to mobility are being considered. The rover design, for this study, included a four car train type vehicle complete with a hybrid solar photovoltaic/regenerative fuel cell auxiliary power system (APS). This system was designed to power the primary control vehicle. The APS supplies life support power for four astronauts and a limited degree of mobility allowing the primary control vehicle to limp back to either a permanent base or an accent vehicle. The results showed that the APS described above, with a mass of 667 kg, was sufficient to provide live support power and a top speed of five km/h for 6 hours per day. It was also seen that the factors that had the largest effect on the APS mass were the life support power, the number of astronauts, and the PV cell efficiency. The topics covered include: (1) power system options; (2) rover layout and design; (3) parametric analysis of total mass and power requirements for a manned Mars rover; (4) radiation shield design; and (5) energy conversion systems.

Book Synopsis Radioisotope Power Systems by : National Research Council
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.

Book Synopsis Comparing Nuclear Propulsion Technologies for Crewed Missions to Mars by : Nisha Khan

Available in PDF, EPUB and Kindle. Book excerpt: Comparing Nuclear Propulsion Technologies for Crewed Missions to Mars Current chemical propulsion systems are limited in their ability to support crewed missions to Mars due to their low propellant efficiency and long mission times. Nuclear propulsion technologies offer a potential solution to these challenges, as they are capable of producing higher thrust and propellant efficiency than chemical rockets. This paper compares three nuclear propulsion technologies for crewed missions to Mars: nuclear electric propulsion (NEP), nuclear thermal propulsion (NTP), and nuclear fusion propulsion (NFP). Each technology has its own advantages and disadvantages, and the best choice for a crewed Mars mission will depend on a number of factors, including mission requirements, cost, and risk. NEP systems are the most mature of the three technologies, and they have already been used successfully in a number of space missions. NEP systems use a nuclear reactor to generate electricity, which is then used to power an electric thruster. NEP systems are very efficient, but they produce relatively low thrust. As a result, NEP systems require longer mission times than other nuclear propulsion technologies. NTP systems are less mature than NEP systems, but they offer the potential for higher thrust and shorter mission times. NTP systems use a nuclear reactor to heat a propellant gas, which is then expelled through a nozzle to produce thrust. NTP systems are more efficient than chemical rockets, but they are also more complex and expensive to develop. NFP systems are the most advanced of the three technologies, but they are also the most speculative. NFP systems would use the fusion of atomic nuclei to generate energy, which could then be used to power a variety of propulsion systems. NFP systems have the potential to offer even higher thrust and shorter mission times than NTP systems, but they are still in the early stages of development.
Book Synopsis Priorities in Space Science Enabled by Nuclear Power and Propulsion by : National Research Council
Download or read book Priorities in Space Science Enabled by Nuclear Power and Propulsion written by National Research Council and published by National Academies Press. This book was released on 2006-03-20 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis The Mars Project by : Wernher Von Braun
Download or read book The Mars Project written by Wernher Von Braun and published by University of Illinois Press. This book was released on 1953 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic on space travel was first published in 1953, when interplanetary space flight was considered science fiction by most of those who considered it at all. Here the German-born scientist Wernher von Braun detailed what he believed were the problems and possibilities inherent in a projected expedition to Mars. Today von Braun is recognized as the person most responsible for laying the groundwork for public acceptance of America's space program. When President Bush directed NASA in 1989 to prepare plans for an orbiting space station, lunar research bases, and human exploration of Mars, he was largely echoing what von Braun proposed in The Mars Project.

Download or read book Mission Needs and System Commonality for Space Nuclear Power and Propulsion written by and published by . This book was released on 1993 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear power enables or significantly enhances a variety of space missions whether near-Earth, or for solar system exploration, lunar-Mars exploration and recovery of near-Earth resources. Performance optimizations for individual missions leads to a large number of power and propulsion systems to be developed. However, the realities of the budget and schedules indicates that the number of nuclear systems that will be developed are limited. One needs to seek the ''minimum requirements'' to do a job rather than the last ounce of performance, and areas of commonality. To develop a minimum number of systems to meet the overall DoD, NASA, and commercial needs, the broad spectrum of requirements has been examined along with cost drivers.
