Mars is famously known as the 'Red Planet' because of the rust-iron color of its soil. Vast deposits of what appear to be finely layered stacks of water ice and dust extend from the poles to latitudes of about 80 degrees in both Martian hemispheres. What's next for Europe's Euclid 'dark universe' telescope after stunning SpaceX launch? The Red Planet Mars | Science Mission Directorate Today, thanks to visiting spacecraft, we know that the planet's appearance is due to rust in the Martian rocks. (Image credit: NASA/JPL/Arizona State University, R. Luk). This is because Mars is covered in soil, rock, and dust made from iron oxide which gives the surface a red rusty colour. A study by scientists in 2018 suggested that salty water below the Martian surface could hold a considerable amount of oxygen, which could support microbial life. Earth has two kinds of crust, continental and oceanic, whose average thicknesses are about 25 miles (40 km) and 5 miles (8 km), respectively. The simple explanation for the Red Planet's color is that its regolith, or surface material, contains lots of iron oxide the same compound that gives blood and rust their hue. This reddish color comes from the abundance of iron minerals and dust on the Martian surface. Adam Mann is a freelance journalist with over a decade of experience, specializing in astronomy and physics stories. When the first spacecraft began operating on Mars in the 1970s, planetary scientists started using the word sol to refer to a solar day on Mars.

Channels, valleys and gullies are found all over Mars, and suggest that liquid water might have flowed across the planet's surface in recent times. Both moons are made mostly from rock and iron and may have once been asteroids that got captured by Mars' gravitational pull. Features called recurring slope lineae may have spurts of briny water flowing on the surface, but this evidence is disputed; some scientists argue the hydrogen spotted from orbit in this region may instead indicate briny salts. For sure, some sort of weathering gradually rusted the iron on Mars. Send your name to Mars.
