NASA's MESSENGER probe is making its third and final flyby of Mercury today. Scientists expect to map another 5 percent of the surface, as well as get closer looks at some areas. At closest approach, MESSENGER will be only 142 miles away from the little world, which should result in some very detailed images.
This flyby marks the end of MESSENGER's preliminary mission. If all goes well, it will settle into orbit around Mercury in 2011 and study the planet at close range for years.
