About "Sputnik" crater in Victoria.

[exoscientist]

Can anyone blow up the full 677 Mbyte HIRISE image here:<br /><br />Mars Exploration Rover Landing Site at Meridiani Planum. <br />http://hiroc.lpl.arizona.edu/images/PSP/PSP_001414_1780/<br /><br />to focus on the small crater on the edge of Victoria dubbed "Sputnik"? <br />It's the roundish feature that appears below the "Duck Bay" label in this labeled HIRISE image of Victoria:<br /><br />http://marsrovers.nasa.gov/gallery/press/opportunity/20061006c/rover-color-close-up2-annot_br2.jpg<br /><br />The 3-D image of Sputnik taken by the rover makes it look more like a gash than a round crater: <br /><br />http://marsrovers.nasa.gov/gallery/press/opportunity/20061006a/Sol952B_P2388_L7R1ana.jpg<br /><br /><br /> Bob Clark <div class="Discussion_UserSignature"> </div>

OpenEV is a freeware program that can open and display these large files in the new JPEG2000 format.<br /> Download it here:<br /><br />FWTools: Open Source GIS Binary Kit for Windows and Linux.<br />http://fwtools.maptools.org/<br /><br /> Install the full FWTools not just OpenEV to get it to work.<br />It is pretty fast and does not require overly large amounts of RAM; my PC has "only" 500 Mbytes.<br /> It is not overly user friendly however. It took several tries to get it to crop a portion of the image.<br /> I attached a portion of the image around "Sputnik" crater.<br /> I can't say this is any more revealing than the images already released.<br /> There is a smaller crater below and to the right of Sputnik that looks rather similar to it.<br /> Also to the right of Sputnik there appears to be a small protruding shape with a dark spot on the top.<br /> Perhaps this could be a vent? Or just a mound with dark material on the top.<br /><br /><br /> Bob Clark <div class="Discussion_UserSignature"> </div>
