Here're the latest navcam pictures taken during sol 1850: http://nasa.exploratorium.edu/mars/spirit/navcam/2009-03-18/
Spirit is no longer stuck, but I think the attempt to go on top of HP via the NE path is finished and we are going to the West Valley. A pancam mosaic of the western route is planned for tosol. |

I'm responding to Alan's route map, but like a good UMSFer I'm posting it here to keep chat out of the map thread.
Alan, your map is especially useful, I think, for its view of the slopes ahead of us. It looks as if a drive on the WEST side of von Braun would drop the rover too much, so it might have trouble coming back up on the south side (not to mention, the south side would be bad for sun until deep summer). The best route might be to get around Home Plate and then try to get into the valley between VB and Goddard. I've always thought that the stratigraphy at the SW corner of Home Plate might be the most complete section - it appears to be the highest part of the edge. If it's not too blanketed with debris we might see layering better there than at the NW corner. Of course, we need the overhead map as well... an oblique view like this loses too many places behind the topography. EDIT: fredk (next post) was of course right - WEST side of VB. I corrected it above. I was looking in the wrong direction... duh... Phil -------------------- ... because the Solar System ain't gonna map itself.

It looks as if a drive on the east side of von Braun would drop the rover too much Just to be clear, I assume you mean a drive on the west side would drop the rover too much. It sounds like a good strategy. Basically, since we can presumably always travel downslope, it makes sense to keep as high as you can for as long as you can (as Tesheiner mentioned regarding the drive through West Valley). That way we always can head downslope once we're done with the higher regions. I don't recall hearing it at the time, but this would've been another advantage of the "over HP" route - we would've ended up quite high. Of course that route turned out to be not doable. |
