NASA’s MESSENGER mission has published the first complete topographical map of the planet Mercury. To be precise, it’s a Digital Elevation Model (DEM), a representation of the elevation distribution of territory, or of another surface, in digital format. It’s the product of the processing of data collected by the MESSENGER space probe during its mission ended just over a year ago.
