A Late Holloween

Release Date: November 18, 2013 Topics: Albedo Contrasts, Hollows, NAC, Named Craters Date acquired: September 23, 2013 Image Mission Elapsed Time (MET): 22253846 Image ID: 4875892 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: -2.55° Center Longitude: 354.1° E Resolution: 79 meters/pixel Scale:Warhol is about 91 km (~57 mi.) in diameter Incidence Angle: 78.5° Emission Angle: 35.1° Phase Angle: 113.6° Of Interest: The Warhol crater hosts one of the best collections of hollows found on Mercury's surface. The crater's central peak is surrounded by a network of small hollows and a smooth floor formed from impact melt. The hollows seen in the Warhol crater have high albedos, making them easy to see. 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. 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.
