NPR : On Mars, a rover named Spirit has gotten stuck in soft, alien soil. About two weeks ago, its wheels dug into the Martian soil, and the plucky rover became trapped.
Spirit has been roaming the red planet for more than five years, but its roving days could be over unless scientists and engineers back on Earth can figure out how to get the robot unstuck.
