Unraveling the origin of lunar features like this one is a primary focus of LROC science.ġ00 m/px WAC context image of Atlas crater. When investigating floor-fractured craters, geologists often look for signs of volcanic activity related to an intrusion of magma. A second possibility is that the fractures may be due to an intrusion of magma into the crust below the crater, which uplifted and disrupted the crater floor as it rose. This rebound would supply the uplift that forms the fractures on the floor of Atlas crater.

However, over time the crust can rebound to its original, pre-impact position. During an impact, the energy released compresses the crust. Fractured Atlas is a non-profit organization that serves a national community of artists and arts organizations. Although historically thought as a benign injury with lower neurological risks, current data suggests that this may not hold true for geriatric patients (aged 65 y and older) who may be. One possibility is the slow readjustment of the crust after the crater-forming impact. Fractures of the C1 vertebrae (atlas) are commonly the result of falls and other trauma, which cause hyperextension, or axial compression of the cervical spine. There are two theories for the cause of the uplift. In the case of Atlas, eventually uplift caused the floor to break and pull apart, forming the graben, or fractures. Fractured Atlas is a non-profit technology company that provides business tools for artists. LROC NAC frames allow for a look at the interiors of the fractures, and with stereo images we can measure their shapes.Īfter the impact that created Atlas, the floor of the crater was molten. The question is, what caused the uplift? Floor-fractured craters have been a known lunar feature since the days of the Lunar Orbiters, but with LROC images, geologists are working to better understand how they formed. It is thought that the fractures have wide, flat floors, like a trough (or graben) and that they record a period of uplift of the crater floor. The cause of the fractures that cut the crater's floor is not well understood. The floor-fractured Atlas crater, located at 46.7°N, 44.4☎, is 87 km in diameter. Image number M157303976L, incidence angle 47°, image scale 0.5 m/pixels. (3) Previous prospective studies have reported an association between higher serum cystatin C and an increased risk of hip fracture among postmenopausal women.
