Beckett (crater)

Beckett is a pit-floored crater on Mercury, which was discovered in January 2008 during the first flyby of the planet by MESSENGER spacecraft. Its floor is not smooth and displays a telephone or arc-shaped collapse feature, which is also called a central pit. The size of the pit is 35 × 7.5 km. Such a feature may have resulted from the collapse of a magma chamber underlying the central part of the crater. The collapse feature is an analog of Earth's volcanic calderas.
