Tomorrow: NASA News Conference on Mercury's Polar Regions!

December 10, 2012
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS) Scale: The diameter of Mercury is 4880 km (3030 miles). Map Projection: Orthographic Of Interest: Tune in to NASA's News Conference tomorrow, November 29, 2012, at 2 p.m. EST for new findings about Mercury's polar regions. Due to its nearly vertical spin axis, Mercury's north pole is never fully sunlit. If it were, it might look something like this image, which is an orthographic projection of a global mosaic. The dark area towards the center of the image contains the north pole. 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, MESSENGER acquired 88,746 images and extensive other data sets. MESSENGER is now in a yearlong extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.
