I am trying to quantify Spirit's final resting orientation, but I would generally like to learn how to determine the orientation of either rover for any particular sol. I'm sure this data is in the MMB files somewhere, but I haven't been able to identify it. Likewise, I am sure it is somewhere in the Analyst's Notebook database and/or the Pancam data tracking database, but again, I can't find it.

Spirit's final orientation is the main thing I am looking for, but any orientation assistance would be greatly appreciated.

Thanks.

Now that we have Spirit's final orientation defined I can post the model for others to use in Google Mars. The model has been saved in the correct orientation, so all you'll need to do is drag it to Eduardo's final location in Google Mars. As long as you don't grab the "rotation" handle while you are adjusting it's position, it should appear in exactly the correct orientation.

I got this model originally as a Google Sketchup model. However, the original model was not correctly scaled. I scaled it to the correct size in Sketchup, oriented it to the angles provided by Deimos, adjusted it's vertical position so that the left side wheels would appear partially buried, and then finally exported it as a Collada model that can be easily imported into Google Earth/Mars.

I suspect there may be a general interest in the model, but I thought I would post it here first to see if it worked properly for people and didn't have any bugs I haven't spotted. If no one identifies any problems, I'll post it in the main Spirit thread.

Once you have the model, it is easy to create your own custom views of Spirit in her surroundings.
