THEMIS: Chaos in Morava Valles
THEMIS Image of the Day, September 5, 2019. Located in Margaritifer Terra, Morava Valles is one of several channels that empty northward towards Chryse Planitia. Chaos terrain is typified by regions of blocky, often steep sided, mesas interspersed with deep … 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

HRSC: A chaos found only on Mars
The cracked, uneven, jumbled landscape seen in this image from ESA’s Mars Express forms an intriguing type of terrain that cannot be found on Earth: chaotic terrain. The feature visible here, Aurorae Chaos, is located in the ancient and equatorial … Continue reading

THEMIS: Secondary craters in Margaritifer Terra
THEMIS Image of the Day, March 15, 2017. Today’s false color image shows part of the plains of Margaritifer Terra. The swarm of craters at right was likely produced by the impact of debris ejected from a bigger impact elsewhere … Continue reading
