Ridges on Mars show ice once flowed on the planet

The Mars Reconnaissance Orbiter found something fascinating on Mars! It discovered detailed lines in the Martian landscape that look like ridges. These lines are like clues telling us, that water ice once moved across Mars, changing its surface over a really long time.

The MRO took close-up pictures, and checked the minerals in the area. It's like painting a picture of Mars's history with flowing water. The minerals were laid down in layers, showing us how Mars changed. they even found signs of ancient seas and lakes, like the edges of shores, suggesting that Mars had water in its past. This helps us learn more about the planet's story, and how it has evolved over thousands of years.
