HiRISE: Bedrock riddles of Nili Fossae
This image of the Nili Fossae region, to the west of the great Isidis basin, shows layered bedrock with many impact craters. Nili Fossae is one of the most mineralogically important sites on Mars. Remote observations by the infrared spectrometer … 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: Bedrock on the floor of Kaiser Crater
HiRISE has often imaged inside Kaiser Crater to monitor active sand dunes and gullies. Surrounding these dunes, we often find clean bedrock exposures, because the actively moving sand clears off the dust. Kaiser Crater is 207 kilometers wide and was … 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

HiRISE: Bedrock in the central peaks of Hale Crater
This long image is entirely over the extensive central peak complex of Hale Crater. Of particular interest are bedrock outcrops and associated fine-grained sediments with different colors. This 153-kilometer diameter crater was named after American astronomer George Ellery Hale. [More … Continue reading

HiRISE: In the gullies and bedrock of Ius Chasma
This image was acquired in Ius Chasma, a major section of the western portion of the giant Valles Marineris trough. We see a portion of a steep slope with gullies extending downhill (towards bottom of image). Many of the gully … Continue reading

HiRISE: Living on the edge
Living on the edge. The rim of this crater looks fairly sharp, meaning it hasn’t degraded too much even though it is likely very old. The exposed, light-toned bedrock is a bonus. HiRISE Picture of the Day archive [More at … Continue reading
