Background: I work for a tech company that may be involved in future expeditions to Mars. Our task is to determine whether it is possible to create a sustainable atmosphere for Mars expeditions. 
Request: I am writing a report on how to create a sustainable atmosphere on Mars. My report should include the equipment needed to create the atmosphere, worst case scenarios we should plan for, and the largest number of people that could be sustained by the atmosphere. I am also interested in NASA’s oxygen-generating experiment on Mars. I plan to report on the experiment plan, the experiment itself, and the results of it. I will highlight the incorporation of local materials, if any, in the creation of the sustainable atmosphere.
