HiRISE: Layers in Danielson Crater
This image shows sedimentary rock and sand within Danielson Crater, an impact crater 67 kilometers in diameter, located in the southwest Arabia Terra region of Mars. The rock was formed millions or billions of years ago when loose sediments settled … Continue reading

HiRISE: Wonderful world of Arabia Terra
The wonderful world of Arabia Terra. It’s one of our favorite regions, not the least because of the incredible layered sedimentary rock but also for the composition of the bedrock. Arabia Terra might be one of the oldest regions on … Continue reading

HiRISE: Sedimentary infill
Interaction. This crater and many of those surrounding it are filled with layered sedimentary material. There are various theories for the origin of this layered fill, and this image will help to constrain the relationship of the fill to the … Continue reading

HiRISE: Layers in Tikhonravov
Layers in Tikhonravov. The objective of this observation is to examine layers outside of a crater within the 344-kilometer diameter Tikhonravov Crater. Tikhonravov is believed to have once held a giant lake and was named after Mikhail Tikhonravov, a Russian … Continue reading
Evidence for fluvial deposition in Arabia Terra
[Editor’s note: From a paper by Joel Davis and six co-authors recently published in the Journal of Geophysical Research.] A Diverse Array of Fluvial Depositional Systems in Arabia Terra: Evidence for mid‐Noachian to Early Hesperian Rivers on Mars • Fluvial … Continue reading

HiRISE: Abstract art in Ius Chasma
Sometimes Mars’ surface is just beautiful as seen through the eyes of HiRISE. This is one example on the floor of Ius Chasma, part of Valles Marineris. The region has had a complex history of sediment deposition, deformation, erosion, and … Continue reading
