Ground feature: Curiosity finds funny ‘rock cookie’ on Mars

On December 5, the Curiosity rover discovered an interesting “rock cookie” on the red planet. It has a small, rounded shape that looks like a chocolate cookie. In fact, this photo is just an enlarged view of the Martian surface taken by Curiosity, which presents some interesting circular structures. Such “views” have indulged planetary geologists and members of the Curiosity team.

Susan Schwenzer believes that this scenario may have been formed by the long-term action of rock and water. The so-called “Diagenesis” refers specifically to the process of change that occurs after the deposition of matter.

Curiosity has been investigating land-rich areas of Mars, and data collected during this period is helping scientists delve deeper into the history of water on the red planet.

The ChemCam remote micro-imager on the Mars rover is capable of capturing close-up images at ultra-microscales to help researchers analyze soil and rock composition, as well as the process of weathering.

Curiosity has previously photographed a variety of Martian rocks, across the bedrock, pebble areas, and a bright floating rock observed nearby.

NASA has even shared some very smooth photos of pebbles, such as the pebbles of a small, divinely small shell shown in 2017.

Finally, as the only rover currently working on Mars, Curiosity will soon welcome a new partner, who is expected to arrive in 2020-2021.
