The Moon Has Enough Oxygen to Sustain 8 Billion People for 100,000 Years.
The Moon contains an enormous amount of oxygen—but it isn’t floating in the atmosphere. About 45% of lunar regolith is oxygen by mass, chemically locked inside minerals and glass.
⸻
🧪 According to an estimate by soil scientist John Grant, one cubic meter of lunar regolith contains about 1,389 pounds of oxygen. The exact amount that could actually be recovered would depend on the composition of the soil and the efficiency of the extraction process.
⸻
🌌 The original calculation assumes that the upper roughly 33 feet of lunar regolith across the Moon could be processed and that essentially all of its oxygen could be recovered. Under those idealized assumptions, the amount of oxygen is theoretically enough to support around 8 billion people for roughly 100,000 years.
