RC Passage

All attempts to detect oxygen in the atmosphere of Mars have been unsuccessful, and it can be concluded that the amount of oxygen is not more than one-thousandth part of the amount in the Earth’s atmosphere. Indirect evidence of oxygen is provided by the ruddy colour of Mars, which is unique among the heavenly bodies. This red colour is suggestive of rocks that have been completely oxidized and it may be contrasted with the grey or brownish colour of the rocks on the Moon, which have remained unoxidised because of the absence of oxygen. It appears probable that Mars may be a planet where the weathering of rocks followed by their oxidation, has resulted in the almost complete depletion of oxygen from the atmosphere.
