THEMIS: Wind-etched sediments in Gordii Dorsum
THEMIS Image of the Day, July 10, 2019. The most common active process affecting the surface of Mars today is erosion by the wind. In areas of poorly cemented surface materials, the effect is more easily seen. This image near … Continue reading

HiRISE: Linear ridge network north of Antoniadi Crater
A linear ridge network to the north of Antoniadi Crater. The objective of this observation is to examine a linear ridge network. This network may have been a consequence of fluids raised along faults created by impacts. They have also … Continue reading

HiRISE: Ridges near Nirgal Valles
In this observation, we see a set of straight ridges in ancient bedrock near Nirgal Valles. The patterns indicate fractures from tectonic stresses, but how have they been hardened to now stand in positive relief after billions of years of … Continue reading
