SOLAR SYSTEM

Detailed explanation-1: -Mars is known as the Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red.

Detailed explanation-2: -The reason Mars looks reddish is due to oxidization – or rusting – of iron in the rocks, regolith (Martian “soil”), and dust of Mars. This dust gets kicked up into the atmosphere and from a distance makes the planet appear mostly red.

Detailed explanation-3: -It turns out the red colour comes from the presence of Iron Oxide, a mineral found in the dust that covers almost all of Mars. Iron oxide is the element that also gives rust and blood its red colour. The Mars Rovers named Spirit and Opportunity took samples of this rusty dust to be examined.

Detailed explanation-4: -Mars is often called the “red planet.” It’s red because its surface is covered with rusted particles of iron.

Detailed explanation-5: -The rover drive destination could perhaps be called the “Great Red Spot on Mars” as it seems to indicate the presence of a reddish mineral, hematite, as seen from orbit and in rover spectra.
