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 ...
In the summer of 2008, the TEGA and WCL experiments on the 2007 Phoenix Mars lander found between 3–5wt% (percent by weight) calcite (CaCO 3) and an alkaline soil. [65] In 2010, analyses by the Mars Exploration Rover Spirit identified outcrops rich in magnesium-iron carbonate (16–34 wt%) in the Columbia Hills of Gusev crater. The magnesium ...
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.
NASA's Perseverance rover found water, organics, and chemical energy in a Martian rock, hinting at possible ancient microbial life. NASA Made a World-Shaking Discovery: Compelling Evidence of Past ...
Elysium Planitia – Broad plain that straddles the equator of Mars; Fretted terrain – Surface feature common to certain areas of Mars; Geology of Mars – Scientific study of the surface, crust, and interior of the planet Mars; Glaciers on Mars – Extraterrestrial bodies of ice; Gravity of Mars – Gravitational force exerted by the planet Mars
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...
Launched in 1996, it used the Mars Orbiter Camera (MOC), Mars Orbital Laser Altimeter, and Thermal Emission Spectrometer to show layering on the surface, presence of surface ice, and the mineral hematite. The presence of ice over the surface is essential to understanding why certain water bearing minerals are on Mars.
NASA's Mars Reconnaissance Orbiter, which has been studying Martian terrain since it was launched 12 years ago, recently discovered a feature on the Red Planet's surface that has left researchers ...
