Short Title: CBS Data Integration and POL/PEL Standard Update
Responsible HRP Element: Human Factors and Behavioral Performance
Collaborating Org(s):
Human Health Countermeasures (HHC) Element
Space Radiation (SR) Element
Funding Status: Planned-Funded - Task expected to be within budget
Procurement Mechanism(s):
Directed Research effort to integrate research results, compose updated POLs & PELs as needed, and gain approval through the required control boards  for needed updates (BRES, HSRB, etc.). The study aims address operationally-relevant fitness for duty standards within the context of NASA Standard 3001, Space Permissible Exposure Limits (SPEL) - Quantifiable limit of exposure to a space flight factor over a given length of time, e.g., lifetime radiation exposure. Physical/chemical agent measured, and Permissible Outcome Limits (POL) - Acceptable maximum decrement or change in a physiological or behavioral parameter, during or after a space flight mission, as the result of exposure to the space environment. Biological/clinical parameter measured, e.g., bone density.

RiskRisk of Adverse Cognitive or Behavioral Conditions and Psychiatric Disorders
GapBMed-101: We need to identify, quantify, and validate the key selection factors for astronaut cognitive and behavioral strengths (e.g., resiliency) and operationally-relevant performance threats for increasingly Earth independent, long-duration, autonomous, and/or long-distance exploration missions.
GapBMed-102: Given exposures to spaceflight hazards (space radiation, isolation), how do we identify individual susceptibility, monitor molecular/biomarkers and acceptable thresholds, and validate behavioral health and CNS/neurological/neuropsychological performance measures and domains of relevance to exploration class missions?
GapBMed-103: What are the validated, efficacious treatments (individual or Team-based) and/or countermeasures to prevent adverse behavioral conditions, CNS/neurological, and/or psychiatric disorders caused by either single and/or integrated exposures to spaceflight hazards during exploration class missions?
GapBMed-107: What are the long-term changes and risks to astronaut health post-mission that, when using a continuity of care model, helps retrospectively identify and understand individual susceptibility (e.g., hereditary, dose, thresholds) to mitigate adverse CNS, cognitive, and behavioral health changes resulting from long-duration exploration missions, promoting the behavioral health of current and future crews?
GapBMed-108: Given each crewmember will experience multiple spaceflight hazards simultaneously, we need to identify and characterize the potential additive, antagonistic, or synergistic impacts of multiple stressors (e.g., space radiation, altered gravity, isolation, altered immune, altered sleep) on crew health and/or CNS/ cognitive functioning to develop threshold limits and validate countermeasures for any identified adverse crew health and/or operationally-relevant performance outcomes.

RiskRisk of Impaired Control of Spacecraft/Associated Systems and Decreased Mobility Due to Vestibular/Sensorimotor Alterations Associated with Spaceflight
GapSM-101: Characterize the effects of short and long-duration weightlessness, with and without deep-space radiation, on postural control and locomotion (gross motor control) after g transitions. Critical mission tasks: Ability to stand upright without falling, ability to walk safely without tripping or stumbling, ability to quickly egress from a vehicle, etc.
GapSM-102: Effects of short and long-duration weightlessness, with and without deep-space radiation, on manual control (fine motor control) after g transitions. Critical mission tasks: Hand-eye coordination, robotic tasks, driving (e.g., rovers), docking, landing, manipulating controls/switches/touch-screens, etc.
GapSM-103: Effects of short and long-duration weightlessness, with and without deep-space radiation, on spatial orientation and motion sickness after G transitions. Performance impacts that effect critical mission tasks: G-transition motion sickness, diplopia, hand-eye coordination, autonomic dysfunction, vertigo.
GapSM-104: How do weightlessness-induced changes in sensorimotor/vestibular function relate to and/or interact with changes in other brain functions (sleep, cognition, attention).
