Oxygen gas produced in Mars

It was latest reported that perseverance rover in Mars produced 5.4 gm of oxygen in mars. This oxygen was produced from the carbon dioxide present in the Martian atmosphere. Mars have 96% of carbon dioxide in its atmosphere which doesn't supports the life. 5.4gm of oxygen will supply 10min life to an astronaut. This device was loaded in perseverance which became successful in testing and producing oxygen gas in mars and it became fruitful result for scientist. There is no scarcity of carbon dioxide gas in mars. Carbon dioxide gas were dissociated to produce oxygen gas and carbon monoxide gas as the waste products.  Scientists were trying best to increase the capacity of oxygen production in mars so that in near future this oxygen was utilized by astronauts to survive in mars and to fill the rocket fuel tank.
