One of NASA's Mars Rovers is no longer responding, and NASA is thinking about calling it quits and leaving it in the sandy bed.

Spirit, a solar-powered Rover, sunk into a sand trap in 2009 during a routine drive. NASA attempted to wiggle it free, but Spirit remained stuck. And since it was unable to tilt itself toward the sun, the Rover went into hibernation.

NASA engineers had expected the rover to “wake up” once there was maximum sunlight filtrating the location where it's trapped, but that moment came and went earlier in March, and Spirit remained silent.
