Explore the innermost planet through the MESSENGER mission in this AGU Fall Meeting 2011 Shoemaker Lecture. Delve into Mercury's surface composition, topography, gravity field, and internal structure. Examine the planet's magnetic field, geological history, and unique features like pyroclastic deposits and smooth plains. Investigate the mysterious hollows, impact craters, and polar regions, including potential water ice deposits. Learn about Mercury's hyperdynamic exosphere and its magnetosphere. Gain insights into how our understanding of Mercury has evolved through MESSENGER's observations and measurements, challenging previous assumptions about the planet's characteristics and formation.
