PIA18803: Crossing Paths

Crossing Paths


At the left edge of this color view is a relatively fresh crater, featured previously in this oblique view . Chains of secondary craters can be seen emanating from the crater, but its bright rays have already nearly faded into the background. Bright, relatively blue rays do cross the scene from northwest to southeast, but these are the famous rays of Hokusai crater , located over 1000 km away.

This image was acquired as a high-resolution targeted color observation. Targeted color observations are images of a small area on Mercury's surface at resolutions higher than the 1-kilometer/pixel 8-color base map. During MESSENGER's one-year primary mission, hundreds of targeted color observations were obtained. During MESSENGER's extended mission, high-resolution targeted color observations are more rare, as the 3-color base map covered Mercury's northern hemisphere with the highest-resolution color images that are possible.

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.
