Why planet Mars looks red?
Its red color has to do with the color of its soil. It’s surface is very rich in iron oxides which have this hue. Because it’s rusty! Pictures from the Mars Pathfinder mission showed that there are lots of rocks on the surface of Mars. Pathfinder’s Sojourner rover examined these rocks and found iron in them. Also, a dozen Martian rocks have been found here on Earth – they fell from the sky as meteorites. Those rocks have iron in them too. It’s not pure iron, like you’d find in an old nail or a cannonball, but iron that’s mixed into the minerals of the rock itself.
