Chris, If you can handle downloading 38Mb you can get Maestro - it offers a great way to get 3D rotations etc as well as info on points of interest and the codes JPL are using.

Hi everyone,
While perusing one of the big (eleven-thousand-pixel-wide) panoramic images assembled from the individual images sent back by Spirit ( http://photojournal.jpl.nasa.gov/catalog/pia05049 ), I'm wondering why I don't see "tracks" left in the surface by the airbag-encased lander as it bounced and rolled to a halt. Are "tracks" there and I'm just failing to notice them? Is the surface so hard that no tracks would have been left? Have any such tracks been erased by wind? Other ideas?
On a slightly different topic, when looking at the Mars images, is there a method one can use to orient the images (i.e. how do we tell which way is, say, "north")? Is information regarding image "orientation" available on the web? If I knew which way was "north", say, and if I knew the (azimuth of) the trajectory of the lander when it impacted the surface, then I presume I'd know where to look for any airbag "tracks".
Chris
