Opportunity: Ulysses Crater strewn field
Sol 3780, September 11, 2014. Off the rear of the rover lies a strewn field of rocks, most of them likely ejecta from the Ulysses Crater impact. The lower slopes of the crater lie at upper right in this three-frame-Navcam … Continue reading

Opportunity: Ejecta rock collection in color
Sol 3778, September 9, 2014. The Pancam made close-up views of several of the rocks lying near the rover, which were probably thrown out by the Ullysses Crater impact (see previous post). These false-color images were created by Holger Isenberg … Continue reading

Opportunity: Ejecta from Ulysses Crater
Sol 3778, September 9, 2014. Sharp-edged rocks lie scattered across the ground near Opportunity. These rocks were likely ejected by the meteorite impact that blasted Ulysses Crater, which sits at the southwest end of Wdowiak Ridge. The lower parts of … Continue reading

HiRISE: Sunken and pitted ejecta
The objective of this observation was to examine the edge of impact ejecta from a crater to the north-west of this area (north is up, west is to the left). The ejecta visible in the top left of this image … Continue reading

HiRISE: Ejecta in excess
When impact craters are formed, the material that once resided in the subsurface is blown upward and outward. This material falls back and settles around the newly formed crater into what is called an “ejecta blanket.” It often appears as … Continue reading

Water-carved channels on crater debris
Medium-size craters less than 3 billion years old often show water-carved channels in their debris aprons, according to a new study of mid-latitude craters in Arabia Terra. Previous studies had reported that such features on ejecta aprons were rare. Nicolas … Continue reading
