Cardiovascular effects of long-duration space flight. [PDF]

Health Sci Rep
Abstract Introduction Early studies exploring the physiological effects of space travel have indicated the body's capacity for reversible adaptation. However, the impact of long‐duration spaceflight, exceeding 6 months, presents more intricate challenges.

During the long way to Mars: effects of 520 days of confinement (Mars500) on the assessment of affective stimuli and stage alteration in mood and plasma hormone levels.

PLoS ONE, 2014
For future interplanetary manned spaceflight, mental issues, as well as physiological problems, must inevitably be considered and solved. Mars500 is a high-fidelity ground simulation experiment that involved 520 days of confined isolation for six ...

Loss of physical contact in space alters the dopamine system in C. elegans

iScience, 2022
Summary: Progressive neuromuscular decline in microgravity is a prominent health concern preventing interplanetary human habitation. We establish functional dopamine-mediated impairments as a consistent feature across multiple spaceflight exposures and ...
