The Edge of Erte

August 28, 2013
Date acquired: April 20, 2013 Image Mission Elapsed Time (MET): 8771355 Image ID: 3917367 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 28.14° Center Longitude: 242.8° E Resolution: 29 meters/pixel Scale: The image is 44 km (27 miles) across. Incidence Angle: 40.8° Emission Angle: 20.4° Phase Angle: 61.3° Of Interest: The crater Erte, the pseudonym of Romain de Tirtoff was a Russian born French artist and designer who passed away in 1990. The crater that bears his name is a complex crater that is 48.5 km in diameter (30 miles). Here the flat floor of the crater meets the crater rim and the surrounding ejecta blanket. 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.
