Spirit retrospective, - a few details from my current project Options

[Phil Stooke]

I'm working on Spirit at the moment. I will post a few examples of things as I go.

Right now the important job is updating the contemporary route map by locating the stops on HiRISE images. The existing maps at JPL, for the early part of the mission, were plotted on MOC images with inferior resolution and lighting, so I find many locations were about 15 or 20 m out. So at every site I am making circular panoramas (examples later) for comparison with HiRISE. Here's a first example, a map of the route during the Primary Mission. I have added a few extra placenames from the MER Analyst's Notebook at PDS.

Very nice Phil!

As it happens I've recently been thinking back to some long ago discussion on who-knows-which thread about some even more distant horizon features that could be seen through a gap in the Gusev rim. Is that visible on this panorama? If so where, and if not where's the location? I would like to revisit the precise identity of what may have been the most distant features seen by either rover. I wasn't paying enough attention at the time, but I don't think it was nailed down as thoroughly as it could have been, or could be now with Google Earth Mars or James Canvin-type reverse polar plots, or pgrindrod inter-visibility charts.
