If that's a real picture, its gonna be hard to science it away as natural. It definatly looks like an imprint of a machine leg. I wouldn't be suprized if it is from the Rover tho -yuri
my thoughts exactly. But I've seen sights be faked before. I believe in aliens, but tthis is a strange find. It has to be somewhat recent or it would be buried right? Idk.much about Mars weather but I imagine a lot of snow and ice storms and mmoving sand dunes -yuri
Does Mars have an atmosphere? if it does I'd say wind storms are more likely to have covered it, or uncovered it. Definitely intriguing either way. To me it looks like a plus sign with a circle around it.
Damn....that's the window crank off my 69 bug I drove in high school...I always wondered what happened to that thing....
Some alien was makin it rain and forgot to pick up all his interstellar dollars. Seems the only logical explanation
Is there evidence this was an imprint caused by a stabilizer arm? I havent looked too deeply into the photo, Im wasnt aware this imprint/anomaly has been addressed academically. Has there been other pictures of this rovers stabilizer imprint or pictures of the pattern of the arm? If so, could you provide a reference? Even if there is no evidence, it still could be possible, but if it can be shown it wasnt from the rover, it remains to be explained what it is. Its worth checking out if there is no other explaination.

Ty! I would say that seems pretty likely to be the source. I do wonder why we havent seen more imprints like this in other pictures? Also, the center inside of the cross pattern has a raised bump followed by a dark circular 'trench' which I cant figure out how the screw would cause. It also looks like there is a less defined circular imprint of the same size that touches the upper right side of the defined one. I thought it may be the double screws but they arent that close. Perhaps the actual instrument is a bit different than the one in the picture. Is there any way to figure out and calculate the magnification of the camera and the distance between the lens to the ground. With that we could get an approximate scale reference for the size of the imprint. I suppose that is a lot of work with little chance it is something uncaused by the rover.
I mean I can walk in my backyard and see a strange design in the dirt. Think everyone just shits themselves because it is another planet.
The instrument that left the imprint isn't a camera, it's an x-ray spectrometer. The camera is a separate instrument, so I doubt they use them in tandem all that often.. seems like dumb luck that it caught the imprint, but there have been thousands of photos taken by Opportunity since 2004, have you gone through them all? Here's a different, but similar photo. http://mars.nasa.gov/mer/gallery/all/1/m/3087/1M402241219EFFBW00P2976M2M1.HTML
No I only have weak 3g if that and those pictures take a while to load. I would have thought someone else would have found pictures like this. Btw i didnt say a camera made the mark i said one could figure out the size of the imprint based on the picture and camera data (such as focal length, zoom, distance). This page says the instrument contacts the ground and takes 2-3hr to get a complete analysis. http://marsmobile.jpl.nasa.gov/msl/mission/instruments/spectrometers/apxs/
