This image from NASA’s MESSENGER spacecraft is a colour view of the impact crater Sor Juana on the planet Mercury. The crater interior contains smooth material, probably impact melt, that embays the central peak. The rim is relatively sharp, with well developed terraces. Sor Juana does not have its own rays – the bright ray patches containing chains and clusters of secondary craters that are dotted around the scene originated at Hokusai.
The MESSENGER spacecraft is the first ever to orbit the planet Mercury.
