  2. Effect of spaceflight on the human body - Wikipedia

    en.wikipedia.org/wiki/Effect_of_spaceflight_on...

    The effects of spaceflight on the human body are complex and largely harmful over both short and long term. [1] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton ( spaceflight osteopenia ). [ 2 ]

  3. Effects of ionizing radiation in spaceflight - Wikipedia

    Consideration of the orientation of the human body relative to vehicle shielding should be made if it is known, especially for SPEs [24] Confidence levels for career cancer risks are evaluated using methods that are specified by the NPRC in Report No. 126 Archived 2014-03-08 at the Wayback Machine .

  4. Physiological effects in space - Wikipedia

    en.wikipedia.org/wiki/Physiological_effects_in_space

    The responses of the human body to microgravity exposure during spaceflight involve adaptations at numerous levels. It is believed that skeletal muscle adaptations to microgravity, which affect both muscle mass and function, involve structural alterations in the neural as well as the myofibrillar components of skeletal muscle.

  5. Space adaptation syndrome - Wikipedia

    en.wikipedia.org/wiki/Space_adaptation_syndrome

    Space adaptation syndrome; NASA astronauts acclimating themselves to space adaptation syndrome in a KC-135 airplane that flies parabolic arcs to create short periods of weightlessness. [1] In about two thirds of the passengers, these flights produce nausea, [2] [3] giving the plane its nickname "vomit comet". Specialty: Space medicine Prevalence

  6. ISS year-long mission - Wikipedia

    en.wikipedia.org/wiki/ISS_year-long_mission

    The mission supported the NASA Twins study, which helps shed light on the health effects of long-duration spaceflight. [11] The goal aboard the orbiting laboratory was to understand better how the human body reacts and adapts to the harsh environment of space. [9] Data from the mission was used to improve assessments of crew performance and health.

  7. Central nervous system effects from radiation exposure during ...

    en.wikipedia.org/wiki/Central_nervous_system...

    The goal of space radiation research is to estimate and reduce uncertainties in risk projection models and, if necessary, develop countermeasures and technologies to monitor and treat adverse outcomes to human health and performance that are relevant to space radiation for short-term and career exposures, including acute or late CNS effects ...

  8. Illness and injuries during spaceflight - Wikipedia

    en.wikipedia.org/wiki/Illness_and_injuries...

    Illnesses and injuries during space missions are a range of medical conditions and injuries that may occur during space flights. Some of these medical conditions occur due to the changes withstood by the human body during space flight itself, while others are injuries that could have occurred on Earth's surface. A non-exhaustive list of these ...

  9. Neuroscience in space - Wikipedia

    en.wikipedia.org/wiki/Neuroscience_in_space

    Knowledge of the effects of gravity on CNS functions in humans, as well as elucidation of the basic mechanisms by which these effects occur, will be of direct benefit to understanding the impact of, and providing countermeasures for, long-term exposure of humans to the weightlessness of spaceflight and the partial gravity of Moon and Mars bases.
