Up-To-Date Odometers?, How far have MSL/Opportunity traveled... Options

[Matt Sidor]

Hi, I am starting a project to compare the distances traveled by the MSL, Opportunity, and Spirit rovers at various phases of their respective missions. Does anyone know where on the internet I might be able to find this information? Or, the person at JPL I should contact to ask about this? I am looking for an always up-to-date source of these measurements.

My project idea is to create a web-based odometer for each rover showing how far they've traveled in real time, or to compare these measurements based on XX Sols into their missions. (i.e., how far has Curiosity traveled up until now, and how far did Spirit and Opportunity get on this Sol of their missions?)

An expansion of this idea would be to show their routes on a Google Mars map, with tick marks for distances traveled.

Thanks for your help!
