Scientists Puzzled by Purple Coating on Mars Rocks

NASA discovered a weird purple veneer on a bunch of Martian rocks.
According to National Geographic, the Perseverance rover found evidence of this mysterious coloring on rocks at almost every site the craft has visited on Mars. NASA is not sure why the purple rocks are appearing in different shapes and sizes.
At a recent American Geophysical Union (AGU) conference, a Los Alamos National Laboratory scientist presented data about the purple rocks, but she didn't have a good answer.
Purp is the grandson of the Grand Daddy.

Researchers are analyzing the coating to see if they can find out more about its origins. Some experts think its chemical makeup could tell us something about the environment on Mars.
Since living organisms have created colored rock coating on Earth before, there is a chance that it could be an indicator of life on the Red Planet.

Researchers haven't seen the colors like that before. This is the first time that a rover has been used to uncover these patches.
Bradley Garczynski, PhD student of planetary science at Purdue University, helped present the data to AGU after Perseverance's Mast cam-Z camera allowed Earth-bound researchers to study the coating through "the scientific eyes of the rover."

Scientists hope that the rocks can be brought back to Earth where they will be able to analyze and reach a definitive conclusion about the purple coating's origins. It is hoped that it does not turn out to be a horrible alien fungus that destroys humanity.
There is a purple coating on Mars rocks.

Scientists are very interested in the sign of life on Mars.
