The first danger of a human mission to Mars is also the most difficult to visualize because, well, space radiation is invisible to the human eye. Access to water, healthy food and breathable air. It works at -263 degrees Celsius, which isn't good for superconductors, but it helps to make space already damn cold. The space exposome will be an important unifying concept, since the dangers and risks of space flight are evaluated within a systems biology framework to fully discover the emerging effects of extraterrestrial experience on the human body.
The risk of adverse cognitive and behavioral conditions and psychiatric disorders (BMed) focuses on characterizing and mitigating potential declines in performance and psychological health as a result of the multiple hazards of space flight, including isolation and distance from Earth. Other onboard research supports and expands the factors that contribute to increased stress in orbit, including studies that document reductions in sleep duration 62, 63 and the evaluation of crew responses to habitability and human factors during spaceflight. [64]. Optical coherence tomography analysis of the optic nerve head and surrounding structures in long-duration International Space Station astronauts.
Nutrition research has enormous potential to solve one of the main risks to human health in space exploration missions. The nutritional status of astronauts alters after a long-term space flight aboard the International Space Station. The HRP element of human factors and behavioral performance uses a research strategy that incorporates flight studies with astronauts, research on individuals and equipment similar to astronauts with terrestrial analogs, and works with the Space Radiation Element to use animal models to support research on combined stressors of space flight. While NASA is conducting initial evaluations of diet quality and health, much work remains to be done to document the full potential of nutrition to mitigate bone loss and other pathological processes in space travelers.
Finally, more recent research is being done on the HERA analog at the Johnson Space Center to assess not only individual psychiatric outcomes, but also changes in team dynamics and team performance over time (Fig. Although astronauts successfully achieve the objectives of their mission and have very positive experiences living and working in space, some anecdotal stories from current and former astronauts suggest that psychological adaptation to the environment of long-duration spaceflight can be a challenge. An ultra-precise atomic clock on Earth multiplies the time it takes for a signal to reach a spaceship from the network and vice versa, and navigators use it to determine the ship's position. The United States Space Surveillance Network is monitoring 17,000 objects, each at least the size of a softball, which revolves around the Earth at speeds of more than 17,500 miles per hour; if you count pieces smaller than 10 centimeters, they approach the 500,000 objects.
As they discovered, beyond the zero gravity effect, planetary dust attaches itself to astronauts through static electricity, has sharp edges and follows them back to their spaceships, increasing the chances of dust entering their lungs and causing damage. In addition to monitoring dietary intake during the flight, the nutrition team carries out research to understand the impact and relationship of nutrition with other risks of space flight, such as bone loss and visual impairment, and interaction with exercise and the spacecraft environment, through analog research initiatives in flight and on the ground. .
