Book Description
Most observers would point to the 1969 Apollo moon landing as the single greatest accomplishment of NASA, yet prominent scientists, engineers, and public officials were questioning the purpose of the U.S. space program, even at the height of its national popularity. Defining NASA looks at the turbulent history of the space agency and the political controversies behind its funding. W. D. Kay examines the agency's activities and behavior by taking into account not only the political climate, but also the changes in how public officials conceptualize space policy. He explores what policymakers envisioned when they created the agency in 1958, why support for the Apollo program was so strong in the 1960s only to fade away in such a relatively short period of time, what caused NASA and the space program to languish throughout most of the 1970s only to reemerge in the 1980s, and, finally, what role the agency plays today.

Book Description
This handbook is a companion to NPR 7120.5E, NASA Space Flight Program and Project Management Requirements and supports the implementation of the requirements by which NASA formulates and implements space flight programs and projects. Its focus is on what the program or project manager needs to know to accomplish the mission, but it also contains guidance that enhances the understanding of the high-level procedural requirements. (See Appendix C for NPR 7120.5E requirements with rationale.) As such, it starts with the same basic concepts but provides context, rationale, guidance, and a greater depth of detail for the fundamental principles of program and project management. This handbook also explores some of the nuances and implications of applying the procedural requirements, for example, how the Agency Baseline Commitment agreement evolves over time as a program or project moves through its life cycle.

Book Description
The Apollo 17 flight and lunar landing, the sixth and final lunar landing and third extended science capability mission in the Apollo Program, are discussed with emphasis on the scientific endeavors conducted on the lunar surface. The scientific investigation of the mission is presented in three interrelated types of activities: the lunar surface sampling and observation, the lunar surface experiments, and the inflight experiments. Collection, documentation, and description of the lunar samples are discussed with a preliminary evaluation and analysis. The lunar surface experiments are described, including the results and their relationship to the scientific objectives of each experiment. The geochemical, photographic, geophysical, topographic, and medical data resulting from experiments conducted in flight are presented.

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.
