Oppy's next destination - the Shoemaker Ridge...
(3D version here http://roadtoendeavour.files.wordpress.com/2011/10/sr-3d.jpg ) Some more height...surrounded by lots of gorgeous rocks...view right across Endeavour... our first view too, probably, of the Promised Land in the centre of Cape York where the phylosillicates are waiting to be found... Go get 'em, Oppy! Edit: looks like Oppy's on the move... http://qt.exploratorium.edu/mars/opportuni...84P1211L0M1.JPG -------------------- |

This paper associates phyllosilicates with polygonal lineations in HiRise imagery, and offers some other interesting observations regarding the directions that some of the layers dip.
QUOTE 3. Morphology and Stratigraphy
[10] Images of the phyllosilicate-bearing crater rim segments from the MRO High Resolution Imaging Science Experiment (HiRISE) [McEwen et al., 2007] reveal layering and a range of polygonal textures (Figure 3a), similar in appearance to other phyllosilicate-bearing outcrops in Meridiani [Wiseman et al., 2008; Marzo et al., 2009] and many other locations on Mars [e.g., Wray et al., 2008; Bishop et al., 2008; Ehlmann et al., 2009]. Stereo views (Figure 3b) show that layers within the western rim dip away from the crater interior, as expected if the beds predate Endeavour crater and were back-tilted by the impact. In contrast, bright layers bounding many Endeavour rim segments [e.g., McEwen et al., 2009, Figure 29] dip down toward the crater interior; we cannot clearly determine whether these layers predate or postdate the impact based on orbital images. -------------------- ...Tom

This paper associates phyllosilicates with polygonal lineations in HiRise imagery Thanks for reminding us of that paper, Rocker. And Fig 3c in that paper shows the very polygons we're sitting next to right now!So we know they'll be interested in them. And yesterday there was this cryptic message from Maxwell: QUOTE Driving Opportunity with Tara today. No real obstacles to avoid, but at least our path is zig-zaggy, a nice change of pace from the plains. I can't wait to find out where we're going!( |
