Mars Atmosphere Mine

Scientific Feasibility
I'?m under the impression that a successful manned mission to Mars will be measured by what can be sent back to earth. I think people will be very interested to see and touch objects from mars. I have designed a base that focuses on extracting and storing the necessary resources from the atmosphere for sustainable life and for propellant for return missions to earth.
I read a few articles about some possible executions for a mission to Mars, and I stumbled upon an article by Keli Rea that explains a possible process of in situ resource utilization (ISRU). The article dives into the chemistry of the Mars atmosphere and how it can be mined. In essence, by using an adsorption-based separator a team of astronauts could extract everything from oxygen (required for breathing and possibly an additive for fuel), nitrogen (required for agriculture) and propellant (required for moving around the planet and returning home).
