Huh, now Circle on Mars?

[extrasense]

What is It ???<br /><br />Is it belated Halloween postcard form Martians?<br /><br />A perfect white circle with nose and mouth on it?<br /><br />http://mywebpages.comcast.net/mycommon/2004-11-05-2P152915489ESF89AIP2549R1M1-sun2-stereo1.jpg<br /><br />Could a Rover paint it? Do not panic!<br /><br />ES

Deep Hole in 'Clovis'(False Color) <br /><br /><i>"To the right is a “brush flower” of circles produced by scrubbing the surface of the rock with the abrasion tool's wire brush."</i><br /><br /> Clovis image<br /><br />Besides, if these were genuine circles, kmarinas86 would have already discovered them <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>

As far as I could calculate, the diameter is ~125 mm<br /><br />The RAT diameter is 45 mm<br /><br />If I am correct, it can not be RAT. Do not panic!<br /><br />ES<br />

If you provide the original image URL, maybe we can guess too. It looks more like a "brush" than a RAT. <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>

This NavCam image shows the rock on which the brush is now located in your image.<br /><br />http://marsrovers.jpl.nasa.gov/gallery/all/2/n/298/2N152816992EFF89AIP1665L0M1.JPG<br /><br />I do not see any circle in this older image, so it is clear that Spirit brushed it.<br /><br />Unless the martians made it right before Spirit approached the rock, which means they are hiding somewhere there as we speak <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>

Chemist,<br />I can not figure out which rock on the navcam image you mean. Help me with this, please.<br /><br />ES<br />

 

[thechemist]

The brushing is on the middle left of the biggest rock of the image I linked to in my post (the rock is also in the middle left of the picture). <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>

 

[extrasense]

Yea,<br /><br />I think I have figured it out.<br /><br />It is reflection of antennae, as sun is low and rock is close so such things happen.<br /><br />Thanks for your input<br /><br />ES<br /><br />

 

[thechemist]

You 're welcome !<br /><br />This close-up PanCam image is even better for locating where the brushing took place. <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>

 

[extrasense]

No brushing, at all.<br /><br />Just sun shining on the antennae <img src="/images/icons/smile.gif" /><br /><br />ES<br />

 

[thechemist]

If it was shining, wouldn't the shined area change slightly in the left and right eye images ?<br />Anyway, future imagery will tell, we just wait a while <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <em>I feel better than James Brown.</em> </div>
