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.
Download or read book Nuclear Power Systems for Manned Mission to Mars written by Scott J. McGinnis and published by . This book was released on 2004 with total page 118 pages. 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 Mars written by Viorel Badescu and published by Springer Science & Business Media. This book was released on 2009-12-07 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: th th Mars, the Red Planet, fourth planet from the Sun, forever linked with 19 and 20 Century fantasy of a bellicose, intelligent Martian civilization. The romance and excitement of that fiction remains today, even as technologically sophisticated - botic orbiters, landers, and rovers seek to unveil Mars’ secrets; but so far, they have yet to find evidence of life. The aura of excitement, though, is justified for another reason: Mars is a very special place. It is the only planetary surface in the Solar System where humans, once free from the bounds of Earth, might hope to establish habitable, self-sufficient colonies. Endowed with an insatiable drive, focused motivation, and a keen sense of - ploration and adventure, humans will undergo the extremes of physical hardship and danger to push the envelope, to do what has not yet been done. Because of their very nature, there is little doubt that humans will in fact conquer Mars. But even earth-bound extremes, such those experienced by the early polar explorers, may seem like a walk in the park compared to future experiences on Mars.
Download or read book Photovoltaics for Space written by Sheila G. Bailey and published by Elsevier. This book was released on 2022-10-26 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: PV has traditionally been used for electric power in space. Solar panels on spacecraft are usually the sole source of power to run the sensors, active heating and cooling, and communications. Photovoltaics for Space: Key Issues, Missions and Alternative Technologies provides an overview of the challenges to efficiently produce solar power in near-Earth space and beyond: the materials and device architectures that have been developed to surmount these environmental and mission-specific barriers. The book is organized in four sections consisting of detailed introductory and background content as well as a collection of in-depth space environment, materials processing, technology, and mission overviews by international experts. This book will detail how to design and optimize a space power system's performance for power-to-weight ratio, effectiveness at end of operational life (EOL) compared to beginning of operational life (BOL), and specific mission objectives and goals. This book outlines the knowledge required for practitioners and advanced students interested in learning about the background, materials, devices, environmental challenges, missions, and future for photovoltaics for space exploration. - Provides an update to state-of-the-art and emerging solar cell technologies - Features comprehensive coverage of solar cells for space exploration and materials/device technology options available - Explains the extreme conditions and mission challenges to overcome when using photovoltaics in space
