This is a set of two images, with the ‘before’ image on top and the ’after’ image on the bottom. The pair is meant to highlight how rolling the spacecraft will allow scientists a clearer view of more layering at Mars’ poles. The background of the image shows an eye chart like the ones used by eye doctors to test vision. Both radar images are black and white. The top image shows a vague, white radar reading that represents rock layering. The bottom image is much stronger, showing multiple rock layers.

Sometimes eye doctors need only to make slight adjustments to lenses to help one's vision improve. Scientists on Mars Reconnaissance Orbiter's SHARAD (shallow radar) team asked spacecraft engineers to roll the orbiter about 25 degrees. By doing so, the radar team has managed to obtain even higher sensitivity from the instrument as it is shown in the "after" image. The team does not expect to perform these spacecraft rolls routinely but they will not miss the chance if one comes along to "see" these mysterious areas better than before.
