To Ngoc Van's Central Pit
Release Date: May 2, 2011
Topics: Named Craters, WAC



Date acquired: April 22, 2011
Image Mission Elapsed Time (MET): 211938059
Image ID: 161520
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 7 (748 nanometers)
Center Latitude: 53.40
Center Longitude: 245.4 E
Resolution: 216 meters/pixel
Scale: The crater containing the pit is 71 km (44 mi) in diameter.
Incidence Angle: 66.8
Emission Angle: 0.1
Phase Angle: 66.7

Of Interest:

The two largest craters in this image are Burns (43 km in diameter) and To Ngoc Van (71 km in diameter). To Ngoc Van contains an irregularly shaped pit, similar to those seen inside of the craters Beckett, Picasso, and Gibran, among others.

This image was acquired as part of MDIS's high-resolution surface morphology base map. The surface morphology base map will cover more than 90% of Mercury's surface with an average resolution of 250 meters/pixel (0.16 miles/pixel or 820 feet/pixel). Images acquired for the surface morphology base map typically have off-vertical Sun angles (i.e., high incidence angles) and visible shadows so as to reveal clearly the topographic form of geologic features.

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, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
