Most impact craters are circular, but not all. The crater on Mars has a unique oblong shape and is an impact crater. What happened?
Most craters are circular in shape because of the impact. There are impact craters in Noachis Terra, a large region on Mars. Simple craters are small bowl-shaped, smooth-walled craters.
Complex craters are large craters with complicated features, such as terraces, central peaks, and rims and walls. One of the craters in the lead image is located in Noachis Terra and can be created by impacts at a very low angle.
Scientists from the HiRISE camera don't think that would explain the crater's shape. It is a complex crater with some tell-tale features that might explain its shape.
Blocks of material in the northeast and northwest corners look like they have slid into the crater, according to the HiRISE team. The crater has been extended in 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110 888-739-5110
This is an oblong impact crater where the shape is due to a small body hitting the surface at a very shallow angle. The depression is called Orcus Patera since newer impact craters dot its surface.
You can see all of the craters at the website. HiRISE is the most powerful camera ever sent to another planet, and is one of six instruments onboard the Mars Reconnaissance Orbiter. It has taken hundreds of thousands of high-resolution images of the Mars surface.
