19. How big are the oxygen tanks? Will there be enough air to last? (LM) (A K2S Question)

From The Space Library

Liquid oxygen is stored in tanks on board your spacecraft. These tanks are used to re-fill the oxygen used on an EVA. Some very intelligent people on the ground know in advance how much oxygen you will need during your space trip and will make sure you have enough stored oxygen to last. The oxygen tanks on board the spacecraft are pretty large and will not be changed out once you leave the Earth. In the future, you may have personal oxygen tanks which can be re-filled or changed out in your spacesuit, but that is not the current method.
