To better understand these reactions, Wang's team, which includes researchers from six universities in the United States, China, and the United Kingdom, studied the isotopic makeup of chlorine, oxygen, and carbon produced by these discharges. They found a consistent depletion of heavier isotopes across all three elements.

"Because isotopes are minor constituents in materials, the isotopic ratios can only be affected by the MAJOR process in a system. Therefore, the substantial heavy isotope depletion of three mobile elements is a 'smoking-gun' that nails down the importance of dust-induced electrochemistry in shaping the contemporary Mars surface-atmosphere system," says Wang.

These isotopic patterns act like fingerprints, pointing to dust-driven electrochemistry as a dominant force shaping Mars today.

God’s up there watching earth like ‘this isn’t working out so hot, maybe I should give it another go on mars instead.’
