Story Synopsis
Mars is often called the Red Planet. This story explains that Mars isn’t painted red—it’s more like it has a dusty ‘rust’ coat. Miluna shares that Mars’s rocks and soil contain iron, the same kind of metal that can rust on Earth. When iron reacts with oxygen, it can form reddish minerals. Over a long time, Mars’s wind spreads dusty particles across the planet. That fine dust gives Mars its famous color when we look through telescopes or see photos from spacecraft. The tone stays gentle and curious, inviting kids to connect space science to everyday life. Curiosity stories like this make big topics feel friendly—and bedtime can still feel cozy.
