Human System Risks

Risk of Adverse Health Effects Due to Host-Microorganism Interactions

Exposure to the spaceflight environment evidence indicates alterations in microbial virulence and astronaut immune function.

Human System Risks

Risk of Adverse Health Outcomes and Decrements in Performance due to Inflight Medical Conditions

Regardless of mission length or objectives, all human spaceflight requires some degree of in-mission medical support. The transition from a gravitational environment to microgravity, coupled with living in a closed-loop environment, can result in variable physiological effects and health risks.

Human System Risks

Risk of Acute and Chronic Carbon Dioxide Exposure

Hostile, enclosed spaceflight environments (including space vehicles and suits) do not have the benefit of natural carbon dioxide (CO2) removal. In these environments, equipment (e.g., the Carbon Dioxide Removal Assembly, lithium hydroxide, and amine systems) control CO2 levels and mitigate consequences of elevated CO2 exposure.

Human System Risks

Risk of Adverse Cognitive or Behavioral Conditions and Psychiatric Disorders

Exposure to the isolation and confinement of spaceflight can result in decrements in cognitive and behavioral functioning.

Concern of Venous Thromboembolism

Note: The Concern of Venous Thromboembolism is historical and now a component of CV Risk. Stagnant or reverse flow in the internal jugular vein has been observed in 6 of 11 crew members (55%) tested in-mission on approximately flight day 50; one crewmember was found to have an occlusive internal jugular vein thrombus requiring treatment […]
