ESA's reactive oxygen species detection project, supported through ESA’s Technology Development Element, will include the initial design of a large scale reactor device to periodically extract oxygen from soil, termed ‘oxygen farming’. Solar UV irradiation will then replenish their oxygen supply within a matter of hours. The estimate is that a 1.2 hectare (3 acre) area would yield enough oxygen to keep a single astronaut alive.
