The Mars Rovers are alive and well. They are in the midst of the Martian winter season, so they will not be getting as much sun light on their solar arrays as they would need for extended movement for awhile, but they are still operating and will resume their travels as soon as the seasons change.

The rover Spirit did find a possible meteorite a few weeks ago. The rock in the center foreground of this picture is suspected of being an iron meteorite. The panoramic camera on NASA's Mars Exploration Rover Spirit took this image during the rover's 809th Martian day (April 12, 2006). The foreground rock, informally named "Allan Hills" has a smoother texture and lighter tone than other rocks in the area. The texture and glossiness of this rock reminded some members of the rover science team of a rock called "Heat Shield Rock," which was observed by Opportunity, Spirit's twin, in the Meridiani region of Mars more than a year ago. Examination of that rock's composition confirmed it to be an iron meteorite. Observations of Allan Hills with Spirit's miniature thermal emission spectrometer indicate that it is very reflective, like Heat Shield Rock. They are the first likely meteorites found by Spirit.
