Scientists want to use new technologies to make oxygen on Mars, and rocket fuel

Researchers at the University of Lisbon in Portugal and the University of Porto believe that the future of humans going to Mars can use the atmosphere of Mars to create the oxygen needed to live on Mars. Vasco Guerra, the lead author of the study, stated: "The Martian manned mission will be the next major goal for us to explore the universe. However, creating a breathable environment is a very big challenge."

Guerra and colleagues are studying the properties of cold plasma and exploring how it can be used to convert industrial emissions of carbon dioxide into hydrocarbon fuels. Guerra explained that “cold plasma is one of the best media for the decomposition of carbon dioxide. Through direct electron collisions and the conversion of electrical energy into vibrational stimulation, carbon dioxide will decompose into oxygen and carbon monoxide.”

Mars' carbon-rich atmosphere gives it excellent conditions for on-site resource utilization (ISRU). The low temperature on the surface of Mars can even make this decomposition process more efficient: Low temperatures can slow down the reaction, so more carbon dioxide molecules can Transform and separate into breathable oxygen and carbon monoxide gas.

Guerra said: “Experts have proposed using carbon monoxide as a propellant for rockets. Cold plasma decomposition provides an alternative solution to Mars’ manned mission. This method not only provides a stable and reliable supply of oxygen. And it can provide fuel for the rockets. Such a system will obviously simplify the logistical supply of Mars missions. It will be self-sufficient and reduce astronauts' risks. The reduction of Mars transport demand will also reduce the Mars mission cost."
