What contribution they made to our knowledge and understanding of the solar system:


The spacecraft revealed more of Mercury than has ever been seen before.lmages and data reveal Mercury as a unique, geologically diverse world with a magnetosphere far diffeent than the one first discovered by Mariner 10 in 1975.
