The International Space Station has been in orbit for over 25 years, and during this time, the air supply systems have undergone significant improvements. However, the need for regular maintenance, repairs, and upgrades has pushed engineers to develop even more reliable systems for future spacecraft. One of the critical components of the air supply system is the oxygen generator, which uses water and electrolysis to produce oxygen. The water is collected and purified from various sources, including sweat, exhalation, and urine, and then used to make oxygen and hydrogen through electrolysis.
The electrolysis process involves the use of an electrolyzer, which is a device equipped with two electrodes, one positive and one negative. When an electric current is applied, the electrolyzer breaks down the water molecules into oxygen and hydrogen gases. The oxygen collects near the positive electrode, and the hydrogen gas bubbles form near the negative electrode. However, the process of separating the oxygen and hydrogen gases is complex and requires the use of magnets and other equipment.
Researchers are currently working on a new system that uses magnets to separate the oxygen and hydrogen gases, known as the Magnetohydrodynamic Oxygen Generation Assembly or MOGA. The MOGA system has the potential to revolutionize the way oxygen is generated in space, making it more efficient, reliable, and sustainable. The MOGA system is still in the research phase, but it has significant implications for future space missions, including trips to Mars and beyond.
