To answer Ustrax's querries from the other thread, I think we can now see more of the
The leftmost (Endeavour north rim) and middle (far rim) features look similar. But it looks like we can see more stuff on the right, which is Endeavour south rim and Iazu. The view we had a few sols ago (2133) of Iazu was still partly obscured by dunes, so it makes sense that we can see more now. I can't see Bopolu in the navcams, though it could be there and buried in the jpeg noise... |

ngunn,
I don't think the distant horizon can be part of Iazu, it just doesn't stretch that far east. Also, it looks more 'hazy' than the rest of Iazu. Looking at Google Mars it does suggest that we should have an horizon about 10km (ish) beyond Endeavour in that direction. Doug, I'd love to have a CTX base map of the area. Not sure how much time I'll have to do any further analysis, but here are some ID's of CTX images that would cover all of Endeavour and Iazu. P13_006135_1789_XN_01S005W P15_006847_1770_XN_03S005W P17_007849_1793_XN_00S005W Stu, Rui has named everything around here hasn't he? James -------------------- |

James My personal favorite is P21_009141_1780_XI_02S005W_080708, because it was taken with a very small emission angle (and is thus nearly perfectly Nadir), and so high-frequency topography is least distorted in this image, compared to others. I'm working on a new CTX/HiRISE mosaic for my route mapping for the project, and put this CTX mosaic together some time ago (so it doesn't include much of Iazu). At least it's not so big I can't paste it here (I *think* >> edited to add, oops! It's an order of magnitude too big!). Scaled up to match the overlying HiRISE images in something like Photoshop, it's about 100GB, though! Fortunately, Arcmap and Global Mapper don't resample to match the scales. -Tim. |
