Finding calcium carbonate in the Martian soil leads scientists to believe that the site had been wet or damp in the geological past. During seasonal or longer period diurnal cycles water may have been present as thin films. The tilt or obliquity of Mars changes far more than the Earth; hence times of higher humidity are probable.

Calcium (Ca) is the fourth most abundant element in the lunar highlands, present in anorthite minerals (formula CaAl 2 Si 2 O 8). [45] [48] Calcium oxides and calcium silicates are not only useful for ceramics, but pure calcium metal is flexible and an excellent electrical conductor in the absence of oxygen. [45]
Calcium metal is found in some drain cleaners, where it functions to generate heat and calcium hydroxide that saponifies the fats and liquefies the proteins (for example, those in hair) that block drains. [48] Besides metallurgy, the reactivity of calcium is exploited to remove nitrogen from high-purity argon gas and as a getter for oxygen and ...

There appear to be huge reservoirs under Mars, scientists have said. Evidence suggests that there are vast lakes of liquid water under the surface of the red planet, according to a new study.
Nili Fossae is a group of large, concentric grabens on Mars, in the Syrtis Major quadrangle. They have been eroded and partly filled in by sediments and clay-rich ejecta from a nearby giant impact crater, the Isidis basin. [1] It is at approximately 22°N, 75°E, and has an elevation of −0.6 km (−0.37 mi).
