Why yes, in fact, we do still have two functioning rovers on Mars, still producing science, thank-you-very-much:

The US space agency's robotic rover Spirit has sent back a partial panoramic view from the summit of "Husband Hill" at Gusev Crater on Mars.

Spirit was still sending down data that makes up the colour 360-degree picture when Nasa held a news conference.

As with Apollo, there's more than a little humor to be found in the fact that, when we could send anything at all to another planet, the most successful thing we explore with there is...

A car.
