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.

Protecting astronauts against the harsh radiation environment of space is one of the major hurdles to human presence in space in the twenty-first century. Future exploration class missions to the Moon and Mars will require a long-duration presence of astronauts in space outside of the protective barrier of the Earth's atmosphere and geomagnetic field. Space radiation outside of the protection of Earth is a complex hybrid environment of highly energetic and heavy charged cosmic ions and energetic protons generated as a result of solar activity. It was established in previous studies that conventional radiation shielding methods that use materials to slow down and fragment the heavy charged ions are incapable of protecting per NASA's career space radiation limit, for deep-space, long-term missions. Therefore, other strategies must be used to shield astronauts on long-duration space missions adequately. Electrostatic radiation shielding, in which an electrostatic field is used to deflect charged particles, was investigated as an alternative by various researchers. All prior investigations concluded that the magnitude of potentials needed to generate a field that can provide significant protection is beyond the reach of present-day technology. In this work, a set of configurations for electrostatic radiation shielding was investigated. This work proposes a novel concept of using multiple conductors of lower-magnitude electric field and repetitively arranging them in three-dimensional space to generate a cumulative electric field, which, together with passive shielding, can provide significant protection. Multiple combinations of such configurations were identified. A set of optimized electrostatic settings and passive shielding materials were used to characterize shielding efficacy against deep-space radiation.

The NASA Radiation Health Program has supported basic research over the last decade in radiation physics to develop ionizing radiation transport codes and corresponding data bases for the protection of astronauts from galactic and solar cosmic rays on future deep space missions. The codes describe the interactions of the incident radiations with shield materials where their content is modified by the atomic and nuclear reactions through which high energy heavy ions are fragmented into less massive reaction products and reaction products are produced as radiations as direct knockout of shield constituents or produced as de-excitation products in the reactions. This defines the radiation fields to which specific devices are subjected onboard a spacecraft. Similar reactions occur in the device itself which is the initiating event for the device response. An overview of the computational procedures and data base with some applications to photonic and data processing devices will be given. Wilson, John W. and Cucinotta, F. A. and Shinn, J.

Spacecraft depend on electronic components that must perform reliably over missions measured in years and decades. Space radiation is a primary source of degradation, reliability issues, and potentially failure for these electronic components. Although simulation and modeling are valuable for understanding the radiation risk to microelectronics, there is no substitute for testing, and an increased use of commercial-off-the- shelf parts in spacecraft may actually increase requirements for testing, as opposed to simulation and modeling. Testing at the Speed of Light evaluates the nation's current capabilities and future needs for testing the effects of space radiation on microelectronics to ensure mission success and makes recommendations on how to provide effective stewardship of the necessary radiation test infrastructure for the foreseeable future.
