Summary
[edit]DescriptionRing of Ridges MESSENGER 2frame.mos.jpg |
English: Unnamed crater (as of Nov. 2024) in Borealis Planitia, located northeast of Hokusai crater, defined by wrinkle ridges in a circular pattern.
Of Interest: A large (180-km diameter) crater occupies the scene, but it has been almost completely buried by the volcanic plains that make up the northern smooth plains. The rim of the buried crater, especially in the southeast, has helped to localize compressional deformation, leading to a wrinkle-ridge ring. The center is criss-crossed by extensional graben. These images were acquired as part of MDIS's high-incidence-angle base map. The high-incidence-angle base map complements the surface morphology base map of MESSENGER's primary mission that was acquired under generally more moderate incidence angles. High incidence angles, achieved when the Sun is near the horizon, result in long shadows that accentuate the small-scale topography of geologic features. The high-incidence-angle base map was acquired with an average resolution of 200 meters/pixel. |
