Perchlorate (ClO4- ) is widespread in the solar system having been detected on Earth, on Mars, in chondritemeteorites and in lunar samples. On Mars, perchlorates expand the potential for habitable conditions by loweringthe freezing point of liquid water in the formation of brines. In future manned space exploration their presenceposes a hazard to human health, however, it also represents opportunities as a source of oxygen and fuel. Despitetheir prevalence, the mechanism(s) of perchlorate formation in different solar system environments are poorlyunderstood. Here we demonstrate that perchlorate can be generated through the mechanical activation of silicatesin the presence of chloride.
