After nearly eight years of interplanetary travel, the BepiColombo mission—ESA and JAXA’s joint endeavor launched on October 20, 2018—is now poised to deliver groundbreaking insights into Mercury’s surface topography. At the heart of this scientific breakthrough is the Laser Altimeter (BELA), a precision instrument designed to measure Mercury’s elevation with millimeter accuracy.
As the spacecraft enters its final orbital phase around the innermost planet, BELA will generate high-resolution 3D maps of Mercury’s terrain, revealing tectonic features, impact craters, and volcanic plains that have long puzzled planetary scientists. The data from BELA will help researchers understand Mercury’s geological evolution, including how its crust has shifted over billions of years due to cooling and tidal forces.
