Spirit update -- waiting for spring & the Martian core

Well, thanks to science_at_nasa , we now know more about the poor stuck Martian rover Spirit's new career path.  It seems that a less-mobile rover is just the thing to help Earthbound observers learn amazing things about the core of the red planet.

Find the full article, "Spirit's Journey to the Center of Mars," here.  It includes a Spirit's-eye view of the rover's predicament.

I continue to be fascinated by how much these cheap little explorers are doing for our knowledge of Mars -- years after they were supposed to turn up their mechanical toes & fall silent.  There is still the Martian winter to get through, though . . . and there's some question as to whether Spirit managed to tilt its solar panels properly. 

Think spring, folks!
