摘要

The dry rock outcrops on the martian plains of Meridiani Planum are thought to have once been bathed in and shaped by acidic waters, based on evidence collected by NASA's Opportunity rover in its seven years on the red planet.rnHow those ancient waters became so acidic, however, has been an open question. A new study suggests that these acid waters were created when iron-rich ground water rose to the surface of Mars and underwent chemical reactions — changing the state of the iron and boosting the acidity of the waters.
