Scientists could use the technology from the Viking landers to create oxygen farms on Mars - Universe Today by AndyTomaswick
Model of the Viking lander that performed the experiments that inspired the search for the current tool under development.Therefore, any technique to eliminate those potentially dangerous materials is welcome. In our bodies, antioxidants play the role of reactive agent fighters. Whereas Mars or the Moon doesn’t have such a defense mechanism, humans might build one.
Such a binary check would be useful for more than just whether or not there would be potentially harmful chemicals in the area – it would also help limit the scope of the search for former life on these worlds. Reactive oxygen species would destroy any biological matter they come into contact with, so the chances of finding a fossil or another signature biomarker around large amounts of reactive species would be negligible.
That supply could be continuous because reactive species are constantly being created on these unprotected worlds by UV bombardment from the Sun. If the oxygen farming tool unlocks all the oxygen from the reactive species in a specific area, simply leaving it exposed to direct sunlight would again make it oxidized, allowing the same tool to repeat the process yet again.
