All images for Sol 526:


This object is fairly close to the rover and therefore due to the clarity of the image, the rectilinear shape is quite unambiguous, at least from the angle we can see.


1. Displays some symmetry consistent with a possibly carved or manufactured object.

2. Has two elements possibly indicating an artificial origin a) A 'stepped' character to the left, and b) Two parallel, possibly hollowed, sections.


A random rock that has some resemblance to a honed building block, but which appears so only because of the angle of imaging.​
