Book Description
"This Report has been prepared at the request of the National Aeronautics and Space Administration (NASA). It is the second phase of a two-phase effort intended to provide guidance to NASA concerning the health effects and mission impacts of space radiation exposure on the central nervous system (CNS) of crew members. The first phase of effort resulted in the National Council on Radiation Protection and Measurements (NCRP) Commentary No. 25, Potential for Central Nervous System Effects from Radiation Exposure During Space Activities. Phase I: Overview, which described the critical issues surrounding the potential short- and long-term consequences of space radiation on the CNS and laid the groundwork for a more comprehensive investigation that is the basis of this Report. This Report summarizes the steps and approaches needed to more fully understand the risk of CNS effects following radiation exposures in space and provides guidance for radiation protection, including risk management. NCRP has identified knowledge gaps regarding the implementation of a comprehensive and effective radiation safety program to protect astronauts against the potential for early and late CNS effects from space radiation"--

Book Description
NASA's current missions to the International Space Station (ISS) and potential future exploration missions involving extended stays by astronauts on the lunar surface, as well as the possibility of near- Earth object (NEO) or Mars missions, present challenges in protecting astronauts from radiation risks. These risks arise from a number of sources, including solar particle events (SPEs), galactic cosmic rays (GCRs), secondary radiation from surface impacts, and even the nuclear isotope power sources transported with the astronauts. The serious early and late radiation health effects potentially posed by these exposures are equally varied, ranging from early signs of radiation sickness to cancer induction. Other possible effects include central nervous system damage, cataracts, cardiovascular damage, heritable effects, impaired wound healing, and infertility. Recent research, much of which has been sponsored by NASA, has focused on understanding and quantifying the radiation health risks posed by space radiation environments. Although many aspects of the space radiation environments are now relatively well characterized, important uncertainties still exist regarding biological effects and thus regarding the level and types of risks faced by astronauts. This report presents an evaluation of NASA's proposed space radiation cancer risk assessment model, which is described in the 2011 NASA report, Space Radiation Cancer Risk Projections and Uncertainties-2010. The evaluation in Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation considers the model components, input data (for the radiation types, estimated doses, and epidemiology), and the associated uncertainties. This report also identifies gaps in NASA's current research strategy for reducing the uncertainties in cancer induction risks.

Book Description
This comprehensive encyclopedia serves the needs of biomedical researchers, space mission planners and engineers, aerospace medicine physicians, graduate students, and professors interested in obtaining an up-to-date and readable introduction to bioastronautics, the science of humans in space. Following the excitement and progress of the birth of the space age in the fifties and sixties, with the successes in human space flight – culminating with the Moon landings – the field of bioastronautics retreated into the more workmanlike arena of successively longer stays in low Earth orbit. At this time, major new initiatives are ahead both in human and robotic space exploration. The International Space Station, along with the developing Chinese space station and lunar program, will permit the development and testing of the means of astronaut protection for long duration missions – eventually to Mars and its moons, as well as visits to asteroids, other NEOs, and the Lagrange points. New life support systems and innovative approaches to radiation protection beyond Earth’s magnetic field will all be developed and tested. Meanwhile, the search for extraterrestrial life, past or even present, is accelerating – with the spectacular finds of Martian water and the discovery of potentially habitable extra-solar planets. A new generation of scientists is ready to attack a new set of problems, and is in need of an efficient, accurate and searchable means of discovering the essentials of the field. This reference work also covers the challenges, past achievements, and potential solutions inherent to the safe exploration of distant space and the search for life off our planet. The entries summarize the tertiary literature and include sufficient data and illustrations to introduce each topic, while avoiding the length and detail of scientific review articles.

Book Description
The subject of this volume in the Astrophysics and Space Science Library is Electro magnetic Radiation in Space. It is essentially based on the lectures given at the third ESRO Summer School which was held from 19 July to 13 August, 1965, in Alpbach, Austria. Fifty-eight selected students attended the courses representing the following countries: Austria (2), Belgium (1), Denmark (1), France (12), Germany (10), Italy (7), Netherlands (2), Spain (4), Sweden (6), Switzerland (3), United Kingdom (9), United States (1). Thirteen lectures courses and nine seminars were given by sixteen different scientists in total. In this book the courses and seminars have been classified in three parts according to the kind of radiation which they mainly deal with: Ultraviolet Radiation, X Radiation and Cosmic Radiation. These parts can be broken down further in theo retical and observational aspects, whereas in the first and second part solar as well as stellar ultraviolet- and X-radiation can be distinguished. * Due to various reasons the publication of this volume had to be delayed; it was therefore judged appropriate to bring the text up to date. The various lecturers have been asked to revise the manuscripts and to eventually add new information which has been acquired in this rapidly evolving field of space astrophysics. Most authors have responded positively to this request, some even have completely rewritten the manuscript.

Book Description
NASA's long-range plans include possible human exploratory missions to the moon and Mars within the next quarter century. Such missions beyond low Earth orbit will expose crews to transient radiation from solar particle events as well as continuous high-energy galactic cosmic rays ranging from energetic protons with low mean linear energy transfer (LET) to nuclei with high atomic numbers, high energies, and high LET. Because the radiation levels in space are high and the missions long, adequate shielding is needed to minimize the deleterious health effects of exposure to radiation. The knowledge base needed to design shielding involves two sets of factors, each with quantitative uncertaintyâ€"the radiation spectra and doses present behind different types of shielding, and the effects of the doses on relevant biological systems. It is only prudent to design shielding that will protect the crew of spacecraft exposed to predicted high, but uncertain, levels of radiation and biological effects. Because of the uncertainties regarding the degree and type of radiation protection needed, a requirement for shielding to protect against large deleterious, but uncertain, biological effects may be imposed, which in turn could result in an unacceptable cost to a mission. It therefore is of interest to reduce these uncertainties in biological effects and shielding requirements for reasons of mission feasibility, safety, and cost.

Book Description
Our anatomy and physiology have been completely shaped by Earth's gravity. All body systems function in synergy with this unseen force. Yet, as we journey further and longer into space, our bodies must conform to a new reality, wherein gravity is absent or reduced, cosmic radiation threatens and our social and familial connections become distant. Into Space: A Journey of How Humans Adapt and Live in Microgravity gives an overview of some of the physiological, anatomical and cellular changes that occur in space and their effects on different body systems, such as the cardiovascular and musculoskeletal, and touches on cultural and psychosocial aspects of leaving behind family and the safety of Earth. It further addresses the complexity of manned space flights, showing how interdisciplinary this subject is and discussing the challenges that space physiologists, physicians and scientists must face as humans seek to conquer the final frontier.
