Variation of halogens in martian soil calls for an atmosphere-surface cycle

A team of scientists found evidence for bromides converting to reactive gases in Martian soil, leading to variable sulfur-chlorine ratios. This could alter existing models of aqueous processes and oxidants on Mars, affecting the search for life. The study also suggests that volatilized halogens may have impacted subsurface distribution.
