Question

What was the Mars Rover's (aka spirit rover?) maximum speed?

Answer 1

Around 5 kilometers per hour. Yes their average speed was slow, but thats not what you asked was it. Anyway its quite slow cause they weren't built for speed. They were built to work.

Answer 2

First off, *is* is the verb tense you're looking for, both Spirit and Opportunity are still running, years past their 'warranty expiration'.

The answer is, not fast at all. Maybe a few centimetres per second, flat out. Around a kilometre per year has been their average speed, which includes lengthy stops for science and for waiting for dust storms to subside.
