The MESSENGER spacecraft is still going strong around Mercury the closest planet to the Sun. Considering the environment this spacecraft is doing spectacular work.
This is Mena crater, nice resolution too as this crater is 15 km (9 mi) across. I keep thinking “wings” coming out of the crater. Check the links in the image caption below to put things in perspective.
From the MESSENGER website:
Here we get a closer look at the fresh, bright-rayed crater Mena. Solidified impact melt forms a smooth pond on the western side of the crater floor. This asymmetry is due to the fact that Mena formed on the sloping rim of an older crater, as seen in this wider view.
This image was acquired as a targeted set of stereo images. Targeted stereo observations are acquired at resolutions much higher than that of the 200-meter/pixel stereo base map. These targets acquired with the NAC enable the detailed topography of Mercury’s surface to be determined for a local area of interest.
