Prospects for Mars Rover Spirit Escape are looking Bleak

Attempts to free Spirit will now be hampered further since another drive wheel appears to have failed.  This addition problem which reduces the available traction already compromised by a previous wheel failure earlier in the mission, will make it even more difficult to extricate the rover from its sand trap. http://bit.ly/52Drm2

Mars Rover Spirit makes another atempt to free itself

Another carefully planned maneuver was executed on the 28th Nov 09 to extricate Spirit, but it ended with another wheel stall. This JPL post shows a brief animation of the wheelspin. Since starting the extrication process, Spirit has progressed a total of 16mm in the forward direction http://bit.ly/8TkIQ6

One wriggle at a time, sand trapped Mars Rover Spirit makes tracks

Extricating a stuck vehicle remotely on another planet requires a lot of patience, Spirit makes it's first minute manoeuvre on the long road to freedom. http://bit.ly/916CrY
