Mars Oxygen ISRU Experiment

The Mars Oxygen In-Situ Resource Utilization Experiment is a technoligical experiment on the NASA Mars 2020 rover Perseverance trying to find out if oxygen can be created on Mars by using carbon dioxide. On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis. This was the first experimental extraction of a natural resource from another planet for human use. The technology may help a possible human mission to the planet to provide breathable oxygen.

ⓘ Electrolysis

Electrolysis is a scientific way of splitting substances. Electrolysis means electric-splitting and involves the separation of substances through an electric current.

Metals above carbon in the reactivity series are extracted by electrolysis.

                                     

1. Uses

Electrolysis is used in the mining industry to split reactive metals from their ores after they are taken from the ground. Electroplating is also used to plate cover things with metal because it costs less than using, for example, solid gold to make jewellery.

Many beauty shops use electrolysis or electrology to remove hair. This is done by "electrocuting" the hair so it splits along its root.

Electrolysis makes the anions negative ions go to the anode positive electrode and the cations positive ions go to the cathode negative electrode. So, for example, oxygen would go to the anode and iron would go to the cathode.
