III. The Present of Humans in Space: Current Understanding of the Impact on Body, Mind, and Technology
2. Psychological Impact of Space Travel on Astronauts
Subtopics:
Isolation and Confinement:
Astronauts experience extreme isolation, limited social contact, and confinement in small spaces for long periods.
Team Dynamics and Group Cohesion:
The importance of cooperation, communication, and mental resilience in small teams under stress.
Mental Health Concerns:
Anxiety, depression, and stress, especially in prolonged missions such as those aboard the International Space Station (ISS).
Sleep Disruption and Circadian Rhythm:
Astronauts experience disturbed sleep cycles due to the lack of a regular day-night cycle.
3. Current Technological Advancements for Overcoming Space-Related Challenges
Subtopics:
Space Suits and Mobility:
Modern space suits designed for spacewalks and protection from extreme temperatures, radiation, and micrometeoroids.
Radiation Shielding:
New technologies to protect astronauts from harmful cosmic radiation (e.g., spacecraft shielding, potential use of water or magnetic fields).
Life Support Systems:
Advanced systems that provide oxygen, clean water, and food while removing CO2 and waste products.
Artificial Gravity and Muscle Conditioning:
Concepts for creating artificial gravity, and exercise regimens to counteract muscle and bone loss (e.g., the use of resistance machines on the ISS).
1. Effects of Microgravity on the Human Body
Subtopics:
Muscle Atrophy:
In microgravity, muscles used for standing, walking, and lifting on Earth weaken and shrink.
Fluid Shifts and Cardiovascular Impact:
Fluids move to the upper body, affecting circulation and heart function.
Visual and Neurological Effects:
Space travel causes visual impairment due to changes in intracranial pressure.
Space adaptation syndrome, including nausea and disorientation.
Bone Density Loss:
Extended exposure to microgravity can cause bones to lose calcium and become weaker.
