The effect of spaceflight and microgravity on the human brain [PDF]

Journal of Neurology, 2017
Microgravity, confinement, isolation, and immobilization are just some of the features astronauts have to cope with during space missions. Consequently, long-duration space travel can have detrimental effects on human physiology. Although research has focused on the cardiovascular and musculoskeletal system in particular, the exact impact of ...

Medical Implications of Space Radiation Exposure Due to Low Altitude Polar Orbits [PDF]

Aerosp Med Hum Perform. 2018 Jan 1;89(1):3-8, 2017
Space radiation research has progressed rapidly in recent years, but there remain large uncertainties in predicting and extrapolating biological responses to humans. Exposure to cosmic radiation and Solar Particle Events may pose a critical health risk to future spaceflight crews and can have a serious impact to all biomedical aspects of space ...

Limitations in Predicting the Space Radiation Health Risk for Exploration Astronauts [PDF]

Nature Microgravity, Vol 4:8 (2018), 2017
Despite years of research, understanding of the space radiation environment and the risk it poses to long-duration astronauts remains limited. There is a disparity between research results and observed empirical effects seen in human astronaut crews, likely due to the numerous factors that limit terrestrial simulation of the complex space environment ...

High-Intensity Interval Training: A Potential Exercise Countermeasure During Human Spaceflight [PDF]

Frontiers in Physiology, 2019
High-intensity interval training (HIT) is an effective approach for improving a range of physiological markers associated with physical fitness. A considerable body of work has demonstrated substantial improvements in cardiorespiratory fitness following ...

Spaceflight-induced neuroplasticity in humans as measured by MRI: what do we know so far? [PDF]

npj Microgravity, 2017
Space travel poses an enormous challenge on the human body; microgravity, ionizing radiation, absence of circadian rhythm, confinement and isolation are just some of the features associated with it.

Human spaceflight: to infertility and beyond

International Journal of Reproduction, Contraception, Obstetrics and Gynecology, 2019
Garrett-Bakelman FE et al, demonstrated a spectrum of molecular and physiological changes attributed to spaceflight in their recently published “NASA Twins Study”.1 During his 340 days in space onboard the International Space Station (ISS), one of a pair of monozygotic twins was not only challenged by noise, isolation, hypoxia, and alterations in the ...

Effects of Spaceflight on Human Skin [PDF]

Skin Pharmacology and Physiology, 2021
During both short- and long-duration spaceflight, several health problems can occur, including those of the skin. Astronauts in space and after returning to earth experience erythematous, burning, itchy, dry, sensitive, and thinning skin. Other skin problems, such as infections, abrasions, lacerations, delayed wound healing, and accelerated skin aging,

Uncertainty Quantification of Thermophysical Property Measurement in Space and on Earth: A Study of Liquid Platinum Using Electrostatic Levitation

Journal of Astronomy and Space Sciences, 2023
A study of uncertainty analysis was conducted on four key thermophysical properties of molten Platinum using a noncontacting levitation technique. More specifically, this work demonstrates a detailed reporting of the uncertainties associated with the ...
