Narrow Angle Camera (NAC) and Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
Mercury's diameter is 4880 kilometers (3030 miles)
The above image shows an orthographic projection of this global mosaic
centered at 0°N, 180°E. Caloris basin
is prominently featured in this view, dominating the northern hemisphere. Just south of Caloris lies the 225-km-diameter basin, Mozart
. Towards the center of the globe, Tolstoj
is visible with an annulus of low-reflectance material
. Beethoven basin
is just visible along the eastern edge of the globe.
The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation
are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury?
section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
