False color images of Spirits tracks using L2,L4,L7<br /><br />Something very strange going on here folks, I very highly recommend time laps imaging for the next <br />couple sol's on these tracks.<br /><br />2P208940362EL4M1 <div class="Discussion_UserSignature"> Ron Bennett </div>

Look at the circled item below that is in one of these time-lapse RGB images. This seems to me<br />to be seepage of some unknown gas or some unknown movement of an object. Note the green <br />color appearance in the image above, that to me from my past experience can be the result of <br />either a artifact in one of the images or a movement of some unknown material.<br /><br />For kicks and giggles later I may tell you the rest of the story on another thought that might <br />apply here.<br /><br />Note the three images taken below are from the Left pan-cam - top L2, middle L4, bottom L7, <br />taken in sequence at different times. <br /><br />All items in each image may not appear in all three RGB filter, that’s because they are predominately <br />block by the color filter from view. Sometimes a light object in one RGB filter image will be darker <br />in another one but in most cases they will be something in at least two of the three filters to<br />help identify it. I have been looking for this type of evidence from the MER rovers, this is one <br />of a very few images of over three thousand processed RGB images that I have found <br />where there is a miniscule image different than the other two that may be caused by some <br />dynamic movement. <br /><br />With all that said it probably is nothing, an artifact, but if it isn't then we <br />should take a closer look.<br /><br />Note: The time difference between the first and second filter image, L2 to L3, is 14 sec, the<br /> difference between the second and third filter image, L4 to L7, is 71 sec. What ever happened, <br />happened within that combined time interval - 85 sec.<br /><br /><br /> <div class="Discussion_UserSignature"> Ron Bennett </div>

No sooner did I say something about some form of seepage looking movement coming out of <br />the surface, JPL might be thinking along the same line. The Spirits left Pam cam is taking time <br />lapse imaging using L6 filter only on the last two sol. By using the same filter and taking images at<br /> different times you can combine them together to make a motion like picture of the area, and <br />then you look for movement in the image. I saw another one using L2 image from a different set <br />of RGB filter images from Spirits site. Don't know if what I am seeing can be visible using the L6 filter?<br /> Below is the Spirit images, 17 each, using L6 filters that came back on sol 933,934<br />Don't know if they are looking for the same effect as I witnessed, I hope so.<br /><br />Another very plausible idea is that it is the result of micro-asteroid impacts during a meteor storm. <div class="Discussion_UserSignature"> Ron Bennett </div>

The nature of the Victoria apron, and its abruptness intrigue me greatly. RLB, could you please post more pictures of this boundry? <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center"><em><font color="#0000ff">- - - - - - - - - - - - - - - - - - - - - -</font></em> </div><div class="Discussion_UserSignature" align="center"><font color="#0000ff"><em>I really, really, really miss the "first unread post" function.</em></font> </div> </div>

No problem. Here are three more; I have more that will be included on my monthly update with higher resolution.<br /><br />1P208081232EL2M1 <div class="Discussion_UserSignature"> Ron Bennett </div>

RLB,<br /><br />So far I have seen no microcraters on the Victoria apron as I go through the raw photos from Opportunity. Odd. Very odd, in fact - I expected the opposite.<br /><br />If you happen to find any, please post.<br /><br />thanks! <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center"><em><font color="#0000ff">- - - - - - - - - - - - - - - - - - - - - -</font></em> </div><div class="Discussion_UserSignature" align="center"><font color="#0000ff"><em>I really, really, really miss the "first unread post" function.</em></font> </div> </div>

<i>So far I have seen no microcraters on the Victoria apron as I go through the raw photos from Opportunity. Odd.

Interesting how it's getting flatter the closer to Victoria we get.

I agree paulanderson. It is most strange. Any ideas why? I would have thought that the opposite would be true also, (MER A Spirit approaching Bonneville Crater, the surface got rougher & rougher, the closer she got). Victoria Crater appears just the opposite.<br /><br />Could the difference in underlying geology (Aerology being Mars) be the reason. In Gusev Crater, the ejecta blanket was broken up pieces of basaltic volcanic lava. Such a surface has great structural strength.<br /><br />Meridiani Planum, is thought to be a dried up sea bed, made of sediments, much weaker & softer.<br /><br />rlb2 keep posting your great images. I for one really appreciate them.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Here are some unusual tiny pebbles seen in a recent Opportunity MI photo from the Victoria annulus. What is odd are the tiny holes in some of the pebbles.<br /><br />(I got this photo from the UMSF forum from a post by SacramentoBob).<br /><br />I was wondering if one of our geologists could comment on these unusual tiny pebbles. My guess is that they are some type of tiny geode, in which a concretion formed around a salt crystal, which subsequently then dissolved out from a later water contact, leaving a hollow sphere with a tiny hole. This implies that the water contact which dissolved out the salt was not nearly as briny as the original brine in which the salt had first crystallized.<br /> <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center"><em><font color="#0000ff">- - - - - - - - - - - - - - - - - - - - - -</font></em> </div><div class="Discussion_UserSignature" align="center"><font color="#0000ff"><em>I really, really, really miss the "first unread post" function.</em></font> </div> </div>

Looks like the spherules, blueberries, at the landing site. Hope this doesn’t mess up your text, it is just too <br />important to miniaturize any smaller. <br /><br />Here is a look at a L7 only colorized pan-view image of the Victoria Crater, notice the light colored layer just below <br />the crater rim??? I can’t wait for all three RGB filter images to come out. <br /><br />Another question that needs to be asked is; if below the top layer of rocky surface there is nothing but dust <br />and sandy looking regolith then what does this mean? Victoria Crater looks fairly new by its sharp profiled <br />rim? Was the top layer sculpted out flat by a more recent pool of water covering the whole Meridian crater <br />basin which must have been a more recent event than first proposed?<br /> <div class="Discussion_UserSignature"> Ron Bennett </div>

This is a grayscale pan-view of Victoria Crater, see link below, that JPL stitched together that was <br />taken at a different time of the day. I sharpened it a bit; darkened, added contrast then colorized it.<br />It looks like a good place to enter the crater.<br /><br /><font color="orange">NASA's Mars rover Opportunity edged 3.7 meters (12 feet) closer to the top of the "Duck Bay"<br /> alcove along the rim of "Victoria Crater" during the rover's 952nd Martian day, or sol (overnight<br /> Sept. 27 to Sept. 28), and gained this vista of the crater. The rover's navigation camera took <br />the seven exposures combined into this mosaic view of the crater's interior. This crater has been <br />the mission's long-term destination for the past 21 Earth months. <br /><br />The far side of the crater is about 800 meters (one-half mile) away. The rim of the crater is composed <br />of alternating promontories, rocky points towering approximately 70 meters (230 feet) <br />above the crater floor, and recessed alcoves, such as Duck Bay. The bottom of the crater is covered<br /> by sand that has been shaped into ripples by the Martian wind. The rocky cliffs in the foreground <br />have been informally named "Cape Verde," on the left, and "Cabo Frio," on the right. <br /><br />http://www.spaceref.com/news/viewsr.html?pid=22230<br /><br /></font> <div class="Discussion_UserSignature"> Ron Bennett </div>
