This process supports a chemical reaction that transforms oxidized iron to its reduced form, creating a green hue in the rock ...

Oxidized iron is responsible for the colour of rocks on Earth similar to those found on Mars. It is also what makes the blood red. The green tinge is also common in rocks on our planet.

Mars’s signature red hue may not be due to hematite, as previously believed, but rather to ferrihydrite — an iron oxide that requires water to form. Using a combination of spacecraft data and ...

Right now, Mars is a reddish desert landscape – attractive but dead, and certainly not home to any little green men. Other nearby planets offer even less hope. Mercury is a scorched rock too ...

Similar mechanisms are now being considered for the findings on Mars. Due to safety constraints, Perseverance couldn’t get its SHERLOC and PIXL instruments close enough to the green spot for a ...

However, Dr. Scott Solomon, a biologist at Rice University, sees drastic mutations in humans born on Mars, potentially leading to green skin, weaker eyesight, and brittle bones due to radiation an ...
