Oxygen is a Non-metal in group 16. It has a Cubic crystalline structure. This element has 3 stable isotopes: 16, 17, and 18.

LUNOX is short for Lunar Oxygen, which is oxygen harvested from resources available on the moon. Oxygen is a major requirement for sustaining any human presence on the lunar surface, useful both for life support and also as a major component of rocket fuel. Lunar Oxygen production is one category of In Situ Resource Utilization, or ISRU.

Methods of LUNOX Production

Most of the methods of lunar oxygen production envision the reduction of lunar regolith or rocks to liberate oxygen, although another possible method of harvesting oxygen is to free small amounts of trapped gas from soil by heating. Reduction methods include:

In any Lunox production sequence, it is necessary that all reactants are returned to the initial state.
