“I can create the O2 easily enough. It takes twenty hours for the MAV fuel plant to fill its 10-liter tank with CO2. The oxygenator can turn it into O2, then the atmospheric regulator will see the O2 content in the Hab is high, and pull it out of the air, storing it in the main O2 tanks. They’ll fill up, so I’ll have to transfer O2 over to the rovers’ tanks and even the space suit tanks as necessary.”
