The purpose of the gravity probe is to test one particular predicition of realitivity. This predicition is that a rotating mass will drag space-time around with it. The effect is extremely weak for a body like the earth, but with the current probe, they are estimating that a year in orbit, with a particular orientation, should detect this effect if it exists.
So far, realitivity has show that both space and time are affected by gravity, and the theory has solid grounding. If this experiment does fail to show the effect, then there would have to be a reconsideration of GR.

IF I remember correctly, this experiment has been on the drawing boards for almost 50 years.
