The air supply system is important because we wouldn't have any air to breath. 95% percent of Mars is carbon dioxide and only 0.2% is oxygen. This system is important because without it we would suffocate.

This system looks like a factory. It's black with smoke stacks on the side. Also it has solar panels on the top. It also has a very big electrolysis system.

The parts of the electrolysis are the smoke stacks, solar panels, a door. The electrolysis' parts are the solar battery, container, metal rods, and wires. The smoke stacks are for the smoke to get out. The solar panels are for getting the solar energy for the electrolysis. The door is for getting in and out of the air supply system. The solar battery is for gathering the solar energy and, the container holds the water. The metal rods separate the hydrogen and oxygen from the water. The wires are for transporting the energy from the solar battery to the rods.

The electrolysis works by the rods sending electrolyte through the water. The electrolyte separates the hydrogen and oxygen from the water. The electrodes make the hydrogen go to one side and the oxygen goes on the other side.

If this system works out, we would have air to breath on Mars. If we have enough oxygen then we would breathe out carbon dioxide and the plants would breathe in the carbon dioxide and breathe out oxygen. It would make living on Mars more possible.
