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. 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. One possibility is the slow readjustment of the crust after the crater-forming impact. The floor-fractured Atlas crater, located at 46.7N, 44.4E, is 87 km in diameter. 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. 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. Fractured Atlas will receive grants for the charitable purposes of PROJECT NAME, provide oversight to ensure that grant funds are used in accordance with grant agreements, and provide reports as required by the grantor. The cause of the fractures that cut the crater's floor is not well understood. PROJECT NAME is a sponsored project of Fractured Atlas, a non-profit arts service organization. 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. The interior of a crater-floor fracture within Atlas crater. Historian Don Meadows said he always started any new project by studying all the relevant maps of the area. ![]()
