This composite view of Mars Sol 1587 consists of five individual images from the Left Mast Camera (Mastcam) (MSSS-MALIN) on the Curiosity Rover. Continuing from Sols 1582, 1583 & 1584, more fascinating anomalies that look to be engineered scattered across the Martian landscape.
The composite below has been slightly enhanced to remove the hazy effect of the original image above.
Here are just a few of the many, many anomalies seen from the above composite.
