Further evidence that liquid water once existed on the surface of Mars comes from the detection of specific minerals such as and , both of which sometimes form in the presence of water. The total volume of ice in the south polar cap plus the adjacent layered deposits has been estimated at 1. Magnetic fields in the solar wind drape over Mars, into the atmosphere, and the charged particles follow the solar wind magnetic field lines into the atmosphere, causing auroras to occur outside the magnetic umbrellas. Small quantities of and detected by Mars orbiters are both claimed to be possible evidence for life, as these would quickly break down in the Martian atmosphere. Frozen carbon dioxide accumulates as a comparatively thin layer about one metre thick on the north cap in the northern winter only, whereas the south cap has a permanent dry ice cover about eight metres thick. The duration of this retrograde motion lasts for about 72 days, and Mars reaches its peak luminosity in the middle of this motion.
