What distinct advantage does Mars possess over the Moon concerning the availability of atmospheric gases for construction processing?
Answer
Mars has atmospheric gases like $ ext{CO}_2$ readily available for chemical processing
While both Mars and the Moon offer abundant silicates and oxygen derived from their crusts/regolith for construction purposes, Mars holds a key advantage related to atmospheric resources. Specifically, Mars has atmospheric gases, primarily $ ext{CO}_2$, immediately accessible on the surface. This contrasts with the Moon, where utilizing atmospheric components would necessitate energy-intensive atmospheric capture systems just to gather the necessary feedstocks for chemical reactions related to building material preparation.
