National Aeronautics and Space Administration MESSENGER spacecraft Crashes on Mercury

Going out with a 'bang,' our MESSENGER mission came to a planned, but nonetheless dramatic, end today when it slammed into Mercury’s surface at 3:26 p.m. EDT. The spacecraft's impact at about 8,750 mph created a new crater on the planet’s surface. Among its many accomplishments, the mission determined Mercury’s surface composition, revealed its geological history, discovered its internal magnetic field is offset from the planet’s center and verified its polar deposits are dominantly water ice.
