Spirit uncovers a wealth of information at Troy
Spirit has not been just sitting around during its stuck time, it has been performing scientific test of the area and recently discovered the soil had a crust, indicating variations in climate over millions of years. This discovery alone points to Mars having a more active past, and with so much data gathered from one spot, Troy will be analyzed for some time even after the rover leaves - if the next rescue attempt is successful of course.
Watch out for updates as the rescue continues.
