Answer:

Explanation:
Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it. The atmosphere on Mars is mostly made of carbon dioxide. It is also 100 times thinner than Earth's atmosphere, so even if it did have a similar composition to the air here, humans would be unable to breathe it to survive. In these conditions humans die within minutes unless a pressure suit provides life support. If Mars' atmospheric pressure could rise above 19 kPa (2.8 psi), then a pressure suit would not be required. Mars' atmosphere is dominated by carbon dioxide (CO₂) at a concentration of 96%. Oxygen is only 0.13%, compared with 21% in Earth's atmosphere. Moxie is able to strip oxygen atoms from CO₂ molecules, which are made up of one carbon atom and two oxygen atoms.
