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 diffrent angle, offering an analytical perspective as to its true structure (see image below SPR-001.4).
POTENTIAL FOR AN ARTIFICIAL OBJECT
Distinct angular and machined appearance. Significantly different character in appearance to surrounding rocks, suggesting possibly a pile of technological debris. Lays close to several other unusual shaped objects that are also out of character with the local rocks.
A ventifact (a piece of rock shaped by the erosive action of wind-blown sand).
