NASA Robots on Mars

Introduction

NASA has two robots on Mars. They are Curiosity and Perseverance. Here is their news.

Main Body

Curiosity had a problem. A big rock stuck to its drill. The team moved the robot arm many times. Finally, the rock fell off. Curiosity could not drill for a few days. Instead, it took pictures of other rocks. Now, it needs a new place to drill. Perseverance took many photos of a place called Crocodile Bridge. It took 980 pictures. It made one big 360-degree picture. These rocks are very old.

Conclusion

Curiosity is working again. Perseverance is still studying the Mars crater.
