With four days remaining until MESSENGER's third flyby of Mercury, MDIS captured this NAC image of the approaching planet. Mercury appears as a sunlit crescent, and the MESSENGER spacecraft is quickly approaching at a speed of approximately 3.3 kilometers/second (7,400 miles/hour)! View this animation to watch the many instrument observations planned for the upcoming encounter next week.
