Aerospace technology is one of the most influential science and technology in the world today. It includes space technology , space applications, space science and other parts. It is a comprehensive engineering technology for humans to explore, develop and utilize space and celestial bodies. my country's aerospace industry began in 1956. Although it started later than developed countries, it has made a series of breakthroughs with the efforts of generations of astronauts, not only achieved from scratch, but also gradually reached the forefront of the world.
2022 is a year of bumper harvest in China's aerospace industry. The Question-1 mission team won the 2022 World Space Award, and the construction of space station has also entered the final stage. According to the plan, the space station's Mengtian Experimental Cabin will be launched this month, and people's curiosity about the space station will be further aroused. As we all know, space is a vacuum environment without oxygen . So where does the oxygen that astronauts breathe on the space station come from?
Ant Manor Today’s title: Where does the oxygen you breathe usually come from when astronauts work on a space station?
Options: A, electrolyzed water to generate oxygen, B, carry it from the earth.
Oxygen in the space station is usually obtained by electrolyzing water. Water molecule is composed of two hydrogen atoms and an oxygen atom. Electrolyzing water can produce oxygen and hydrogen . The oxygen produced by electrolyzing water in the space station can be used to breathe astronauts, while hydrogen can be used as fuel for the aircraft, which can be said to kill two birds with one stone. Of course, there are also methods of using oxygen generated by solid oxygen generators.
Water is required to produce oxygen, so where does the water from the space station come from? There are three main sources of water in the space station: the first is the soft water capsule carried by the spacecraft from the ground. The water of these water capsules can meet the daily water use and the needs of astronauts for water quality electrolytic oxygen; the second is the use of water produced by the space station itself; the third is the use of special devices to recycle the water.
Ant Manor Today's answer: Where does the oxygen you breathe usually come from when astronauts work in the space station? Answer: Electrolyze water to generate oxygen.
