RAYdiant Hovnatanian

Date acquired: May 01, 2013 Image Mission Elapsed Time (MET): 9751363, 9751355, 9751351 Image ID: 3986986, 3986984, 3986983 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: -7.39° Center Longitude: 172.9° E Resolution: 394 meters/pixel Scale: Hovnatanian crater is about 34 km (21 miles) long. Incidence Angle: 15.7° Emission Angle: 40.0° Phase Angle: 28.0° Of Interest: Today's color image features Hovnatanian crater, named for Armenian painter Hakop Hovnatanian. The crater's elliptical shape and the bright rays' butterfly pattern indicate that a very oblique impact produced Hovnatanian. The brightness of the rays indicate that they are relatively young features on Mercury's surface. This image was acquired as a targeted high-resolution 11-color image set. Acquiring 11-color targets is a new campaign that began in March 2013 and that utilizes all of the WAC's 11 narrow-band color filters. Because of the large data volume involved, only features of special scientific interest are targeted for imaging in all 11 colors. 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. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
