Moon has enough oxygen for 8 billion people – scientist — RT World News

The Moon’s atmosphere doesn’t contain enough oxygen for human life, but under the planet’s rocky top layer, there’s enough of the gas to sustain eight billion human lives for 100,000 years, according to a prominent scientist.

In a piece penned this week in The Conversation, John Grant, a lecturer in soil science at Australia’s Southern Cross University explained that the Moon was heavy in minerals that bind tightly with oxygen.

Grant claims that, even if one ignores the oxygen tied up in deep, hard rock, the Moon’s regolith – the rocky top layer – which is easily accessible, could hold enough oxygen for eight million people to live for 100,000 years. 

The scientist’s calculation is based on the notion that humans need 800g (28oz) of oxygen a day to survive, and the regolith is some 10m (33ft) deep. He states that the Moon’s regolith is made up of 45% oxygen, all of which is tightly bound to minerals such as silica, aluminium, and iron and magnesium oxides. 

Although rocks may not be breathable, it is possible to extract large quantities of oxygen from them. “But there is a catch: it’s very energy-hungry. To be sustainable, it would need to be supported by solar energy or other energy sources available on the Moon,” Grant notes. 

Grant’s article comes after the Australian Space Agency and NASA signed a deal in October to send a rover to the Moon with the objective of collecting lunar rocks and attempting to extract breathable oxygen from them. 

A Belgian company had also developed experimental reactors that could improve the electrolysis process for making oxygen. The new technology could be sent to the Moon by 2025 as part of the European Space Agency’s in-situ resource utilisation mission.
