29 APPENDIX B NASA Program Human Research Bioastronautics Requirements Document Program Evidence Roadmap (BR) (PRD) Books Poorly integrated ground, crew, Risk of error due to Lack of human- and automation functions1 inadequate availability centered design: Mismatch between crew of information Subrisk of error due cognitive capabilities and to inadequate task demands1 information Immune dysfunction Risk of crew-adverse Same as PRD Interaction among factors: health event due to infections and malignancy altered immune response 1 Poorly integrated ground, crew, and automation functions and mismatch between crew cognitive capabilities and task demands map both individually to specific risks in the PRD. In addition, each of these was combined to result in an extra risk being identified in the PRD and Evidence Books. The following risks were added to the PRD and subsequently transferred to the SLSD (Q: spell out) watch list: Risk of urinary tract dysfunction, risk of impaired vision due to refractive visual changes during long-duration spaceflight, risk of adverse health effects due to exposure to hypoxic environments, and risk of adverse health effects due to prolonged exposure to elevated carbon dioxide levels. The following risks appeared in the BR, but not the PRD or Evidence Books: medical informatics, technologies, and support systems; monitor air quality; monitor external environment; monitor water quality; monitor surfaces, food, and soil; provide integrated autonomous control of life support systems; maintain acceptable atmosphere; maintain thermal balance in habitable areas; manage waste; provide and maintain bioregenerative life support systems; provide and recover potable water; alterations in microbes and host interactions; motion sickness; and impaired fracture healing.
