Things are getting grim on Mars. A rover that cannot move can no longer perform science its instruments were designed to perform.
Quote:
Extrication drives were tried on sols 2138, 2140 and 2142 (Jan. 7, 9 and 11, 2010). Each of these drives employed a new technique of steering the wheels back and forth before driving. … However, even with these new techniques, little forward progress has been achieved. And excessive sinkage continues to occur with each attempt.
Both the right-front and right-rear wheel continue to be non-functional.

It just does not have enough horsepower to get out of a place called Troy.
