caption_attribution_description: English: MESSENGER image of Mercury’s horizon about 56 minutes before the spacecraft’s closest pass by the planet. The peak-ring basin Dürer (named from Mariner 10 photos for the German artist Albrecht Dürer) is visible. The smaller crater Mickiewicz (named for the Polish poet Adam Mickiewicz) can also be seen, with a smaller central peak-ring structure in the middle of its crater floor. In the lower part of the image the 86 km diameter Glinka crater with a bright central pit can be seen.
context_page_description: Glinka is a pit-floored crater on Mercury, which was discovered in 1974 by Mariner 10 spacecraft. Its floor is covered by the smooth plain material and displays a kidney-shaped collapse feature, which is also called a central pit. The size of the pit, which was first noticed in MESSENGER images obtained in January 2008, is 20 × 8.5 km. It is surrounded by a bright pyroclastic deposit. Such a feature may have resulted from collapse of a magma chamber underlying the central part of the crater. The collapse feature is an analog of Earth's volcanic calderas.
