    Astronauts require a consistent supply of oxygen for respiration. The International Space Station (ISS) generates oxygen using electrolysis, which splits water into hydrogen and oxygen. According to NASA, the ISS must maintain a minimum oxygen level of 19.5% for astronaut safety. Monitoring and managing oxygen levels is essential to prevent suffocation and ensure crew health.

  2. Food and Water:
    Food and water are critical for maintaining astronaut health. NASA develops specialized space food that is nutritious and shelf-stable. In space, astronauts consume an average of 3,000 calories per day. Water is recycled on the ISS, with advanced systems purifying wastewater for consumption. Researchers suggest that proper nutrition and hydration foster crew morale and efficiency.

  3. Waste Management:
    Effective waste management systems are necessary to handle human waste and prevent contamination. The ISS uses vacuum toilets that transport waste to storage tanks. The need for proper waste management is evident; it ensures sanitation and hygiene in the confined space environment, thereby diminishing health risks.

  4. Radiation Protection:
    Space exposes astronauts to higher levels of cosmic radiation than on Earth. The ISS is built with shielding materials to reduce radiation exposure. Studies indicate that effective radiation protection can minimize the risks of cancer and other health issues. Understanding radiation’s impacts is crucial for designing long-term missions to Mars and beyond.

  5. Psychological Support:
    Psychological well-being is vital for astronauts maintaining mental health during missions. Isolation and confinement can lead to stress or anxiety. NASA has implemented support systems, including regular communication with family and psychological counseling, to combat these issues. Research indicates that positive mental resilience enhances mission success and performance.

  6. Physical Exercise:
    Astronauts must engage in daily physical exercise to counteract muscle atrophy and bone density loss caused by microgravity. The ISS is equipped with exercise equipment such as treadmills and resistance machines. A Stanford study indicates that exercising in space helps maintain physical health and readiness for reentry to Earth’s gravitational environment.

  7. Communication Systems:
