Mission: MESSENGER.

Instrument: Mercury Dual Imaging System – Narrow Angle Camera.

This image, taken with the Angle Camera (NAC), gives us a stunning close-up view of the floor of Eminescu crater. The high-reflectance patches surrounding the central peaks and scattered across the crater floor are hollows, an unexpected landform found in MESSENGER high-resolution images. Hollows are shallow, irregular, bright depressions whose formation may involve loss of volatile material.

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 Mercuryʼs entire surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.
