Related: About this forumMars Curiosity Rover Finds Weird Sphere
At first glance it looks like an old cannonball or possibly a dirty golf ball. But knowing that Mars is somewhat lacking in the 16th-century battleship and golf cart departments, there was likely another answer. Of course it's nothing man (or alien)-made, despite what your brain might be telling you. It's another fascinating rock. Yep, it's a spherical Mars rock.
According to MSL scientists based at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., the ball isn't as big as it looks it's approximately one centimeter wide. Their explanation is that it is most likely something known as a "concretion." Other examples of concretions have been found on the Martian surface before take, for example, the tiny haematite concretions, or "blueberries", observed by Mars rover Opportunity in 2004 and they were created during sedimentary rock formation when Mars was abundant in liquid water many millions of years ago.

(19,964 posts)4. I've found several concretions in Ordovician outcroppings
Broke them open to find they had built up around a fossilized shell. The largest one I ever found was the size of a softball. I'd been under the impression (mistaken, apparently) that concretions from sedimentary deposits were always formed around an object like a seashell. How does this process work otherwise?

Looks like a gear or a weird cheetos you sometimes find in the bag more than a traffic light...
