PIA18440: Tears Roll Down

Tears Roll Down


This targeted image is a highly detailed view of the wall and floor of an unnamed crater to the north of To Ngoc Van . In the upper-left portion of the image, several small teardrop-shaped craters are present. The elongated shape results from formation on the sloping face of the larger crater's wall. The image is not map projected

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.

Background Info:

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. MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
