Life support systems are a critical component of space missions and other extreme environments where humans need support to survive. These systems provide astronauts and other occupants with the necessary air, water, food, and temperature regulation to sustain life. Life support systems are designed to maintain a safe and habitable environment for humans, including removing waste products, regulating oxygen levels, and controlling temperature and humidity. They are essential for long-term space missions, undersea exploration, and other challenging environments where humans need assistance to survive. Research in this area focuses on improving the efficiency, reliability, and sustainability of life support systems to enable future missions to space and other extreme environments.
