What if the bedrock we see is partly made of ice?
I am not a geologist, so I am asking anyone with knowledge on the topic
if it possible that the bedrock we see in the crater (opportunity site) is not entirely solid rock, but instead is a mixture of ice, dirt and rock (permafrost)? here are some sample images of permafrost as seen on earth, and I find that some of thee images resemble what we are seeing from the rovers http://science.nasa.gov/newhome/head...a/permname.jpg http://www.socc.uwaterloo.ca/_images...permafrost.jpg http://tinyurl.com/ypdfc http://www.steinborn.org/gifs/alaska...permafrost.JPG http://lovelace.ucsd.edu/Ted/Arcticw...0on%20view.jpg I got the idea from this article http://www.space.com/scienceastronom...ce_040229.html WTF |

O eat mi WTF,
I have posted so much and you just chew it down, digest it a little, and spit it up on different newsgroups. Bedrock? The Rovers are now "old" and "cranky", and I guess we're left with what we have as "information".. and cannot ask much else. I expect the next mission to Mars to be "manned" by CIA/Air Force chops. No need to have "data intercepts" of "secure infos"... BTW - I need a lovely true red-head - a little heavy - and with an angel face - for an email "friendship" - I wish my bankteller was available.

Does it look like the "rock" melted and refroze?
http://tinyurl.com/yqka9
Look at the sides of the cut, it looks like the stuff melted and refroze from the heat generated by the cutting tool. See my previous post suggesting we're looking at permafrost instead of solid rock. If anyone already suggested this idea (eg Joe Schmoe), let me know if you got anything to add to support the theory or not. WTF |

Not sure about that, but you might be interested in this shot of the same which was colorized in a unique way by Doug Ellison. He used pancam shots of the RAT hole to give color info for the MI shot.

@newssvr28.news.prodigy.com: http://mer.rlproject.com/index.php?a...pe=post&id=204 This is a very nice image. If you trust the colour as a close approximation it reinforces the theory that the blue berries formed in a single event as there are no clear differences in colour across the cores. The colour is truly unexpected. I still have trouble visualizing these things as blue as they seem to be. They are so radically different from the rest of the geologic environment. One thing just seems inescapable. These blueberries, however they were formed, are trapped in a sandy matrix. What the sand is made of I don't know (they've been hopping up and down about sulphur at JPL so perhaps there was a hot spring nearby at one time). But it is almost certainly something like sand. The voids are characteristic of cemented sandy matrices on Earth (for example where ancient beaches used to exist). This implies water deposition and rock formation by cementation. Water also may account for the "bubbly" muddy appearance on the outside of the rock. Perhaps there was wet (probably briny) sand that over time splashed and layered over the rock then gradually dried out. I'd wager you could scratch it with a thumbnail. Mark |

If the outcrop contained ice , it would have to be very fresh, because ice evapourates fast on mars. And fast means weeks , not millenia. The ice-rock would be covered with fresh powder from the remaining dust. The alpha X ray spectrometer would show a lot of hydrogen. -- http://www.geocities.com/carla_sch/index.html |

Sorry for this - of course an X ray spectromter cannot show hydrogen. -- http://www.geocities.com/carla_sch/index.html |
