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 ...
On Mars, heat can come from molten rock moving under the ground and from crater impacts. Liquid rock under the ground is called magma. When magma sits in underground chambers, slowly cooling over thousands of years, heavier elements sink. These elements, including copper, chromium, iron, and nickel become concentrated at the bottom.

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.
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 ...
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.
NASA's Perseverance Rover has been driving around the surface of Mars since landing on the planet on Feb. 18, 2021, and the latest geological wonder explored by the robotic pioneer is exciting for ...
Martian regolith is toxic, due to relatively high concentrations of perchlorate compounds containing chlorine. [3] Elemental chlorine was first discovered during localised investigations by Mars rover Sojourner, and has been confirmed by Spirit, Opportunity and Curiosity.
Mars has shone red in the night sky for as long as humans have gazed up at the cosmos, fascinating people from the ancient Romans to the present day. "The fundamental question of why Mars is red ...
