In March 2012, a powerful solar storm affected MESSENGER's imagery. In this picture of Mercury's surface, the bright streaks and speckles result from energetic particles from the Sun hitting the charged-couple device (CCD) on the spacecraft's camera. Images acquired during the storm will have to be taken again later in the mission.
