Book Synopsis Movement And Maneuver In Deep Space by : Brian E. Hans
Download or read book Movement And Maneuver In Deep Space written by Brian E. Hans and published by . This book was released on 2020-11-24 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the authors' abstract: "This analytical study looks at the importance of Deep Space Operations and recommends an approach for senior policy leaders. Section 1 presents a capability requirements definition with candidate solutions and technology strategies. Section 2 recommends an acquisition and organizational approach. Section 3 provides an extended strategic rationale for deep space operations as a national priority." And from the Introduction: [this essay] "presents capability requirements, potential solutions, and strategic rationale for achieving movement and maneuver advantage in deep space. In this context, deep space is anything beyond geosynchronous Earth orbit (GEO). Driving the research are two primary assumptions underpinning the need for investment in deep space propulsion. The first assumption is that growing international activity, commerce, and industry in space extends the global commons, thus creating a military-economic imperative for the United States Department of Defense (DoD) to expand its protection of U.S. interests by defending space lines of communication. Although there are wide-ranging reasons to expand the space-faring capabilities of the human species, from the capitalistic to the existential, the fact of its occurrence offers the U.S. immense strategic opportunity. Section 1, operating on this assumption, recommends capability-based requirements for deep space operations given a projected future operating environment.The second driving assumption underpinning this study is that improved movement and maneuver capabilities in deep space offer a wide array of benefits for the current National Security Enterprise, and for this reason alone demands attention in the form of disciplined investment. Furthermore, because the core functional capability required for deep space operations is in-space propulsion, the requirement necessitates a materiel solution.

Book Synopsis From Cave Man to Cave Martian by : Manfred "Dutch" von Ehrenfried
Download or read book From Cave Man to Cave Martian written by Manfred "Dutch" von Ehrenfried and published by Springer. This book was released on 2019-04-05 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the practicality of using the existing subsurface geology on the Moon and Mars for protection against radiation, thermal extremes, micrometeorites and dust storms rather than building surface habitats at great expense at least for those first few missions. It encourages NASA to plan a precursor mission using this concept and employ a “Short Stay” Opposition Class mission to Mars as the first mission rather than the “Long Stay” concept requiring a mission that is too long, too dangerous and too costly for man’s first missions to Mars. Included in these pages is a short history on the uses of caves by early humans over great periods of time. It then describes the ongoing efforts to research caves, pits, tunnels, lava tubes, skylights and the associated technologies that pertain to potential lunar and Mars exploration and habitation. It describes evidence for existing caves and lava tubes on both the Moon and Mars. The work of noted scientists, technologists and roboticists are referenced and described. This ongoing work is moreextensive than one would think and is directly applicable to longer term habitation and exploration of the Moon and Mars. Emphasis is also given to the operational aspects of working and living in lunar and Martian caves and lava tubes.

Book Synopsis Pathways to Exploration by : National Research Council
Download or read book Pathways to Exploration written by National Research Council and published by National Academies Press. This book was released on 2014-09-30 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States has publicly funded its human spaceflight program on a continuous basis for more than a half-century, through three wars and a half-dozen recessions, from the early Mercury and Gemini suborbital and Earth orbital missions, to the lunar landings, and thence to the first reusable winged crewed spaceplane that the United States operated for three decades. Today the United States is the major partner in a massive orbital facility - the International Space Station - that is becoming the focal point for the first tentative steps in commercial cargo and crewed orbital space flights. And yet, the long-term future of human spaceflight beyond this project is unclear. Pronouncements by multiple presidents of bold new ventures by Americans to the Moon, to Mars, and to an asteroid in its native orbit, have not been matched by the same commitment that accompanied President Kennedy\'s now fabled 1961 speech-namely, the substantial increase in NASA funding needed to make it happen. Are we still committed to advancing human spaceflight? What should a long-term goal be, and what does the United States need to do to achieve it? Pathways to Exploration explores the case for advancing this endeavor, drawing on the history of rationales for human spaceflight, examining the attitudes of stakeholders and the public, and carefully assessing the technical and fiscal realities. This report recommends maintaining the long-term focus on Mars as the horizon goal for human space exploration. With this goal in mind, the report considers funding levels necessary to maintain a robust tempo of execution, current research and exploration projects and the time/resources needed to continue them, and international cooperation that could contribute to the achievement of spaceflight to Mars. According to Pathways to Exploration, a successful U.S. program would require sustained national commitment and a budget that increases by more than the rate of inflation. In reviving a U.S. human exploration program capable of answering the enduring questions about humanity's destiny beyond our tiny blue planet, the nation will need to grapple with the attitudinal and fiscal realities of the nation today while staying true to a small but crucial set of fundamental principles for the conduct of exploration of the endless frontier. The recommendations of Pathways to Exploration provide a clear map toward a human spaceflight program that inspires students and citizens by furthering human exploration and discovery, while taking into account the long-term commitment necessary to achieve this goal.

Book Synopsis Human Missions to Mars by : Donald Rapp
Download or read book Human Missions to Mars written by Donald Rapp and published by Springer. This book was released on 2015-10-31 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mission to send humans to explore the surface of Mars has been the ultimate goal of planetary exploration since the 1950s, when von Braun conjectured a flotilla of 10 interplanetary vessels carrying a crew of at least 70 humans. Since then, more than 1,000 studies were carried out on human missions to Mars, but after 60 years of study, we remain in the early planning stages. The second edition of this book now includes an annotated history of Mars mission studies, with quantitative data wherever possible. Retained from the first edition, Donald Rapp looks at human missions to Mars from an engineering perspective. He divides the mission into a number of stages: Earth’s surface to low-Earth orbit (LEO); departing from LEO toward Mars; Mars orbit insertion and entry, descent and landing; ascent from Mars; trans-Earth injection from Mars orbit and Earth return. For each segment, he analyzes requirements for candidate technologies. In this connection, he discusses the status and potential of a wide range of elements critical to a human Mars mission, including life support consumables, radiation effects and shielding, microgravity effects, abort options and mission safety, possible habitats on the Martian surface and aero-assisted orbit entry decent and landing. For any human mission to the Red Planet the possible utilization of any resources indigenous to Mars would be of great value and such possibilities, the use of indigenous resources is discussed at length. He also discusses the relationship of lunar exploratio n to Mars exploration. Detailed appendices describe the availability of solar energy on the Moon and Mars, and the potential for utilizing indigenous water on Mars. The second edition provides extensive updating and additions to the first edition, including many new figures and tables, and more than 70 new references, as of 2015.
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 2009-08-14 with total page 68 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 Next Stop Mars written by Giancarlo Genta and published by Springer. This book was released on 2016-12-30 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the possible manned mission to Mars first discussed in the 1950s and still a topic of much debate, addressing historic and future plans to visit the Red Planet. Considering the environmental dangers and the engineering and design needed for a successful trip, it covers every aspect of a possible mission and outpost. The chapters explain the motivations behind the plan to go to Mars, as well as the physical factors that astronauts on manned missions will face on Mars and in transit. The author provides a comprehensive exposure to the infrastructure needs on Mars itself, covering an array of facilities including power sources, as well as addressing earth-based communication networks that will be necessary. Mechanisms for return to Earth are also addressed. As the reality of a manned Mars voyage becomes more concrete, the details are still largely up in the air. This book presents an overview of proposed approaches past, present, and future, both from NASA and, increasingly, from other space agencies and private companies. It clearly displays the challenges and the ingenious solutions involved in reaching Mars with human explorers.
