How do astronauts breathe in space?
Syed G. Shanawaz, Trichy, T.N .ANSWER: Air management is considered critical for space station/craft where three to seven people share a small enclosed volume. NASA/Marshall Space Flight Center is mainly responsible for designing and building the life support systems that will provide Astronauts a comfortable environment. . These compact and powerful systems collectively called the Environmental Control and Life Support Systems, or simply ECLSS, which includes Water management (including waste water/urine), removal of gases produced inside cabin like Carbon Dioxide, Ammonia, Methane etc., and controlling cabin pressure, temperature, and humidity and fire protection. All systems would have to operate under the restrictions of minimizing volume, mass, energy, and labour. People on the space station get oxygen for breathing in two ways. The first way is to make oxygen from water by zapping it with electricity (electrolysis). Each molecule of water contains two hydrogen atoms and one oxyge
