Is it a problem that there is no oxygen on Mars? The scientist said: This question is the simplest.
However, besides water, oxygen is also indispensable to us. Unfortunately, Mars is extremely short of oxygen. The atmosphere of this red planet is very thin, of which more than 95% is carbon dioxide, while oxygen is only 0. 13%. In contrast, the earth's atmosphere is much more luxurious, 2 1% oxygen. So how to solve the problem of lack of oxygen on Mars?
It is obviously unrealistic to transport it from the earth. It is king to find a way to use local materials. Since the atmosphere of Mars is mainly composed of carbon dioxide, let's make good use of it.
Mars 2020 is a Mars probe that NASA plans to launch in 2020. Scientists assigned it an important scientific task-exploring oxygen production on Mars. It is suggested that Mars 2020 be used to transport some microorganisms (bacteria or algae) to Mars and use photosynthesis to produce oxygen. However, NASA did not adopt this plan, but found another way out.
NASA installed a device named Mo Xie on Mars 2020, which can absorb carbon dioxide in the atmosphere of Mars and produce pure oxygen after complex reaction and treatment. If the test is successful, NASA will release an enlarged version of Mo Xie (100 times) to Mars to produce oxygen-breathing (gaseous) and return fuel (liquid) for future astronauts landing on Mars.
The globalization of Mars is a great project, which needs the relay of many generations, and the oxygen production experiment of Mars 2020 will be a small step and a key step for mankind.
