Cratered Lineated Valley Fill
HiRISE PICTURE OF THE DAY: 2 AUGUST 2021

A Cluster of Craters

A Song of Impact and Ice? Craters appear commonly in clusters on top of mesas in this area but only rarely do the clusters also cover the valley floors which are thought to be ice rich. One of our goals with this observation is to look for deformation of craters at small and large sizes.



Strange Terrain
This image shows material almost completely filling an impact crater northeast of Hale Crater, perhaps water-rich ejecta from the crater itself.

It is often unclear where and why sediment is mobile on today’s Mars. A new paper takes a deeper look.
