What gases make up marss ozone, and would there be enough gases to create a livable atmosphere for humans?
This is an interesting and common question about Mars. There is no ozone layer on Mars, so there isn’t anything to protect people on the surface from the dangerous ultraviolet radiation. The atmosphere on Mars is much thinner than that on earth. The air pressure on Mars is 7 millibars and here on earth it is 1000 millibars. Additionally, the gasses in that atmosphere are almost completely made of carbon dioxide, where we have lots of oxygen on earth. People would need to wear “mars suits” kind of like the astronaut’s space suits in order to survive there. At this point, there is no technology that can change the atmosphere, although that is a common theme in science fiction books. Maybe the technology will be developed by people like you in the future.
