PIA20194: Crater with Scarps in LAMO

Crater with Scarps in LAMO


NASA's Dawn spacecraft viewed this Cerean crater, which is covered in ridges and steep slopes, called scarps on Dec. 23, 2015. These features likely resulted when the crater partly collapsed during its formation. The curvilinear nature of the scarps resembles those on the floor of Rheasilvia, the giant impact crater on Vesta, which Dawn orbited from 2011 to 2012.

The 20-mile-wide (32-kilometer-wide) crater is located just west of the larger, named crater Dantu (see PIA20193 ), at northern mid-latitudes on Ceres. Both of these impact features were captured during Dawn's Survey orbit (see PIA19609 ).

Dawn took this image from its low-altitude mapping orbit (LAMO) at an approximate altitude of 240 miles (385 kilometers) above Ceres. The image resolution is 120 feet (35 meters) per pixel.

Background Info:

Dawn's mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science.
