OBSERVATIONS

This wrench/spanner-like object has a clearly defined artificial, manufactured look about it. Imaged first on Sol 527, further pictures of it appeared on Sols 540 and 541 at a slightly different angle, offering an analytical perspective as to its true structure (see images below).

POTENTIAL FOR AN ARTIFICIAL OBJECT

Distinct angular and machined appearance. Significantly different character in appearance to the other local rocks surrounding it. Also lays close to several other unusual shaped objects, suggesting the possibility that the object is possibly just one piece of a pile of technological debris.  

COMMON EXPLANATION

A ventifact (a piece of rock shaped by the erosive action of wind-blown sand).
