Messenger to Mercury

NASA’s Messenger spacecraft entered orbit around Mercury in 2011 for a one-year mission to this least-explored of the solar system’s inner planets. It flew by Mercury three times before settling into orbit, with each encounter reducing its speed. Messenger will map the planet’s entire surface, measure the chemical and mineral composition of its rocks and soil, measuring its gravitational and magnetic fields, and conduct other observations.
