Mercury's Topography from MLA
Mercury's Topography from MLA

The Mercury Laser Altimeter (MLA) ranges at a wavelength of 1064 nm at an 8 Hz rate and illuminates Mercury's surface in spots between 15 and 100 m across, depending on the MESSENGER spacecraft's range. The MLA has so far returned 10.7 million precise measurements of the elevation of Mercury's northern hemisphere. Shown here is a polar stereographic projection of the topography of Mercury from the north pole to 5° S. The outlines of selected major impact structures are shown as black circles.
