It seems that the Curiosity rover is a bit of a little bug!
NASA released photos of a couple of large messes made by the rover when it first landed on Mars. Curiosity was taken to Mars with what is known as a cruise stage which is a bunch of tools and equipment that helped Curiosity navigate through space.
Shortly before hitting the Mars atmosphere, some of the equipment was dumped so that the descend would be smooth and when these items dropped onto the surface of the Red planet, they left some messy scars!
NASA is looking at this positively, though. They say that the impact sites will allow them to learn more about the surface of Mars as well as about the planet’s atmosphere.
