Date acquired: June 29, 2012
Image Mission Elapsed Time (MET): 249498646, 249498642, 249498638
Image ID: 2108963, 2108962, 2108961
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filters: 9, 7, 6 (996, 748, 433 nanometers) in red, green, and blue
Center Latitude: 32.24°
Center Longitude: 95.65° E
Resolution: 216 meters/pixel
Scale: Fonteyn crater is 29 km (18 miles) in diameter
Incidence Angle: 46.0°
Emission Angle: 25.8°
Phase Angle: 71.9°
Of Interest: This color image of the rayed crater Fonteyn, shows the central portion of its ray system. Rays on Mercury are usually maturity rays, meaning they are composed of fresh material from young craters and over geologic time they are weathered by space until they blend in with the background. Fonteyn is also interesting because of the bright material near the crater.
This image was acquired as a high-resolution targeted color observation. Targeted color observations are images of a small area on Mercury's surface at resolutions higher than the 1-kilometer/pixel 8-color base map. During MESSENGER's one-year primary mission, hundreds of targeted color observations were obtained. During MESSENGER's extended mission, high-resolution targeted color observations are more rare, as the 3-color base map is covering Mercury's northern hemisphere with the highest-resolution color images that are possible.
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.
