"Magic carpet" redux.

[exoscientist]

There has been discussion on Unmannedspaceflight.com and MarkCarey.com/mars that the material revealed in the trenches dug by the stuck wheel on Spirit have the appearance of the "Magic carpet" material seen early on the MER rover mission.<br /><br />http://www.lyle.org/~markoff/processed/2P195962820EFFAQ67P2530L234567M1.JPG<br /><br />Like the "Magic Carpet" which was seen when the air bags were retracted, this arose from material been pressed down and dragged away.<br /><br />If there were thin interstitial ice from atmospheric deposition this ice may have been melted by the squeezing and dragging of the wheel.<br /><br />cf.<br /><br />From: Robert Clark - view profile <br />Date: Wed, Jan 4 2006 1:02 pm <br />Email: "Robert Clark" <rgregorycl /> <br />Groups: sci.astro, alt.sci.planetary, sci.physics <br />Subject: Could We Make A "Solar Still" On Mars? <br />http://groups.google.com/group/sci.astro/msg/f76e921c4b865f2e<br /><br /><br />Bob Clark <br /><br /> <div class="Discussion_UserSignature"> </div>

If you're talking about the "white material" shown in the Sol 787 NavCam image, there is a discussion of the topic at the end of this thread. <div class="Discussion_UserSignature"> <strong><font color="#3366ff">Made weak by time and fate, but strong in will to strive, to seek, to find and not to yeild.</font> - <font color="#3366ff"><em>Tennyson</em></font></strong> </div>

No, the reddish material in the middle of the trench.<br /> Google "magic carpet" and "spirit rover" for a comparison.<br /><br /><br /> - Bob Clark <div class="Discussion_UserSignature"> </div>
