HiPOD: A Layered Mesa near Mawrth Vallis
This target comes from the public via HiWish: “Similar HiRISE images of mounds around Chryse Planitia have revealed stunning and complex stratigraphy, indicative of widespread, regional-scale processes.”

HiPOD: Cracks in a Debris Apron
The apron could be (or could have been) ice-rich, so one possibility is that the fissures are related to ice loss. Scientists think that extensive glaciers covered this region several hundred million years ago.

Wanted to be an astronaut. Wrote to NASA c. 1975 who replied they were designing a space shuttle, and you could go as a scientist instead of a pilot (RAF didn’t train female pilots back then!). So got a PhD in planetary science, did work for NASA, but never as an astronaut.
