Mars is our neighbour planet. Even without a telescope it glows a warm orange-red in the night sky — that is why ancient people called it the "fiery star".
But Mars is not on fire and it is not hot. So what paints it red? Let's investigate, step by step. Tap Next to begin! 🚀
Mars is a rocky planet, just like Earth. Its whole surface is covered in dusty soil and rock. Scientists checked what that soil is made of — tap each cup of Mars dust to peek inside!
Find the cup with the special metal. (Hint: it starts with "I".)
Here's the magic. When iron meets oxygen (a gas in the air) for a long time, it slowly turns into rust — a flaky reddish-brown stuff. You've seen rust on an old bike or gate!
Rust is reddish! So a whole planet covered in rusty iron dust would look… red. 🤔
The rusty dust on Mars is super light. Big Martian winds pick it up into giant dust storms and sprinkle it over the whole planet — even the sky turns pinky-red!
Some people guess Mars is red because it's burning hot, like lava. But remember our clues! Pick the real reason:
Fun fact: Mars is actually freezing cold — colder than Antarctica! The red comes from rust, not heat.

Mars looks red because of rusty dust. Here's the whole story you cracked:
And remember: it's not red from fire — Mars is super cold. It's just very, very rusty. The next time you see rust on an old gate, you can say, "That's the same colour as a whole planet!" 🌌
