Mars rover Spirit may back track its way out of being stuck Alabama Live

NASA Mars exploration managers at the Jet Propulsion Lab, in California, are pondering whether or not to command the Spirit rover to back out over its own tracks in an attempt to free the bogged rover.
The compacted soil could be stronger and allow the Spirit rover to free itself. NASA managers say it will take weeks to free the rover, and cautioned the attempt may not work at all.
