NASA has a robot car on Mars. It is called Curiosity. It has been there for 14 years! Curiosity takes pictures and sends them to Earth. It just found something really cool!
The ground on Mars has special shapes. They look like a honeycomb from a beehive! The shapes are very small. Each one is about 2 to 3 inches wide. They go on and on in every direction!
Scientists are very excited about this. Long ago, Mars may have had water. The cracks may come from old wet mud. This helps us learn about Mars' past. Maybe Mars was once like Earth!
