PIA18533: A Flower in Egonu

A Flower in Egonu


This image is a high-resolution view of the polar crater Egonu . The 'flower' in the crater is Egonu's central peak . Egonu is named after Uzo Egonu, a Nigerian artist (1931-1996). He was known for crossing the boundary between Western and African painting, as he lived in England for most of his life.

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.
