IMAGE DETAILS
MAA Report Ref: MAA-012
Report date: July-August 2017
Research Status: Open - Possible machined artefact
Description: Tool Wrench
Approximate size: 20 cm
Mission: Spirit Rover
Location: Gusev Crater
Found by: Rolf Varga
Image date: Sol 527 June 2005

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