HiRISE: Pits in Hale Crater ejecta
The pits visible here aren’t impact craters. The material they’re embedded into is ejecta (stuff thrown out of an impact crater when it forms) from a large crater called Hale which is not seen in this image. Substances called “volatiles” … Continue reading

HiRISE: Giant cave on a giant volcano
Pavonis Mons is a giant shield volcano similar to (although larger than) those on the Big Island of Hawaii. These volcanoes are mostly made of stacks of overlapping lava flows. These images and digital terrain model (DTM) show a collapse … Continue reading
