The NASA rover Spirit extends its robotic arm to further explore the surface of Mars, seeking physical evidence that water once flowed over the planet's surface.

A careful analysis of the soil near Spirit's landing site may provide that evidence. So far the mission is a success for NASA's engineers. Now the science team is awaiting big results. NPR's Joe Palca reports.
