Perchlorate was detected in Martian soil at the level of ~0.6% by weight. [33] [34] It was shown that at the Phoenix landing site it was present as a mixture of 60% Ca(ClO 4) 2 and 40% Mg(ClO 4) 2. [35] These salts, formed from perchlorates, act as antifreeze and substantially lower the freezing point of water.
