European Space Agency has opened an oxygen plant to produce oxygen out of Moon dust.
45 per cent of Moon dust (regolith) is oxygen according to weight.
Involves heating regolith with a salt up to 950 degrees Celsius and then passing a current through it.
Process allows oxygen to be extracted and the rest to be converted in to metal alloys.
