Inside a Crater
Release Date: August 22, 2012
Topics: NAC



Date acquired: July 09, 2012
Image Mission Elapsed Time (MET): 250306754
Image ID: 2166386
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Center Latitude: 36.24
Center Longitude: 181.8 E
Resolution: 25 meters/pixel
Scale: The crater floor is 37 km (23 miles) in diameter.
Incidence Angle: 83.5
Emission Angle: 54.6
Phase Angle: 138.2

Of Interest: This unnamed crater north of March crater is seen in this dramatic close up of the crater floor and central peak. The floor, while relatively flat and smooth, is marred by multiple smaller craters. The walls of the crater have collapsed down producing small terraces.

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.
