The Man Who Set Mercury to Music

May 10, 2012
Date acquired: January 12, 2012 Image Mission Elapsed Time (MET): 234830851 Image ID: 1254970 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: -17.75° Center Longitude: 44.65° E Resolution: 147 meters/pixel Scale: Holst crater is 170 km (106 mi.) in diameter Incidence Angle: 67.0° Emission Angle: 0.5° Phase Angle: 67.2° Of Interest: This image, taken with the Narrow Angle Camera (NAC), shows Holst crater. A peak-ring basin, Holst is one of 23 Mercury craters recently assigned names by the IAU. Holst was named for English composer Gustav Holst, who is best known for his orchestral suite The Planets — the third movement of which is "Mercury, the Winged Messenger". This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week. 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.
