Human Health in Space Travel: Limitations and Opportunities
Space travel presents unique environmental challenges that enact molecular, cellular, and physiological changes across many regions within the human body. Specifically, the high energy and variable mass of the particles from space radiation present new and unexplored consequences in which astronauts will be at greater risk of deleterious health effects beyond Earth's protective magnetosphere. Longer missions beyond low Earth orbit will result in greater doses of space radiation, increasing the risk of developing degenerative tissue diseases from the accumulation of genetic mutations and high oxidative stress. This thesis maps the findings of space-related biological research on humans and animals exposed to spaceflight effects –to present the risks associated with spaceflight, health responses to these risks, and the mitigative strategies that can be applied to counteract deleterious health effects and ensure successful spaceflight missions in the future.
