The Mare Boreum quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Mare Boreum quadrangle is also referred to as MC-1 (Mars Chart-1). [1] Its name derives from an older name for a feature that is now called Planum Boreum, a large plain surrounding the ...
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 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 ...
Vugs on Mars which may be voids left by Meridianiite when it dissolved or dehydrated. Opportunity found evidence for magnesium sulfates on Mars (one form of it is epsomite, or "Epsom salts"), in 2004. [64] Curiosity rover has detected calcium sulfates on Mars. [65] Orbital maps also suggest that hydrated sulfates may be common on Mars.
In its ancient past, Mars likely contained many of the necessarily ingredients for microbial life to flourish on its surface. Now, a new discovery by NASA’s Perseverance rover shows a trifecta ...
Sometimes water flows through Earth's aquifers, and then evaporates at the surface just as is hypothesized for Mars. One location this occurs on Earth is the Great Artesian Basin of Australia. [194] On Earth the hardness of many sedimentary rocks, like sandstone, is largely due to the cement that was put in place as water passed through.
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.
Curiosity's hard work is once again paying off by turning up evidence that liquid water quite likely exists on Mars at this time. A paper published in Nature Geoscience reveals that data collected ...
